背景技术Background technique
医疗机构日常工作中会产生医疗废水，这些废水基本配置了污水处理系统来进行处理。因医疗卫生场所自身特殊性，该污水、处理污水伴随产生的废气(气溶胶)、渣、泥常携带病菌、微生物等。通常状态下，医疗卫生机构本身常常位于人员流通密集区域；这些水、气(气溶胶)、泥、渣与人的流通存在大量交集，有着巨大的安全隐患。Medical institutions generate medical wastewater in their daily work, and these wastewater are basically equipped with sewage treatment systems for treatment.

The waste gas treatment unit deodorizes and harmlessly treats the waste gas and then discharges it.
作为本发明优选的方案，所述伴生废气处理单元具体为：As a preferred solution of the present invention, the associated waste gas treatment unit is specifically:
在容积上依照污水处理量进行配置，但各单元结构上均为密闭容器，根据上述A类、B类单元中容器内部配置液位传感器与气压传感器(Pn)；The volume is configured according to the sewage treatment capacity, but each unit is a closed container in structure. According to the above-mentioned type A and type B units, the liquid level sensor and air pressure sensor (Pn) are configured inside the container;
该容器结构上除配置该单元特定处理物质的正常可控进、出口外，其物质为污水、渣、泥，进、出口为阀的进、出口和管道进、出口，容器上部配置2路气体进出口，容器上留出的气体进出口均配置可控阀，出口为管道的出口，其中一路作为备用调压口，实现容器内部与特定压力环境的连通，特定气压环境实际上构成整个系统中的基准参考气压，此路气体通道默认状态时关闭的，在特定情况下比如容器内部压力环境出现超设定、无法平衡的偏差后，开启此通道以恢复容器内部压力环境；另外一路是容器内部气体抽取通道，当压力传感器感知到容器内部压力超出预定范围后，就打开阀门，配合外部动力装置对容器内部气体抽取，维持容器内部气体压力；In addition to the normal controllable inlet and outlet of the unit's specific processing materials, the container structure is configured with sewage, slag, and mud. The inlet and outlet are the inlet and outlet of the valve and the inlet and outlet of the pipeline. The upper part of the container is equipped with 2 gases. The inlet and outlet, the gas inlet and outlet left on the container are equipped with controllable valves, and the outlet is the outlet of the pipeline. One of them is used as a backup pressure regulating port to realize the connection between the inside of the container and the specific pressure environment. The specific pressure environment actually constitutes the entire system. The base reference air pressure. This gas channel is closed by default. Under certain circumstances, such as when the pressure environment inside the container exceeds the set and cannot be balanced, this channel is opened to restore the pressure environment inside the container; the other gas channel is inside the container. Gas extraction channel, when the pressure sensor senses that the pressure inside the container exceeds a predetermined range, it opens the valve and cooperates with the external power device to extract the gas inside the container to maintain the gas pressure inside the container;
对于废气产生量较小的A类单元，废气产生、收集原理如下：For Class A units with small waste gas generation, the principles of waste gas generation and collection are as follows:
A类单元在正常工作进行污水处理时，内部呈现气液双相形态；且液体水因挥发或其他原因会持续转化成为气态，改变容器内上半部分空间的气相物质的成份与气压等物理性质，进而影响到容器内气压的变化；When a Class A unit is operating normally for sewage treatment, the interior will be in a gas-liquid two-phase state; and the liquid water will continue to transform into a gaseous state due to volatilization or other reasons, changing the composition and pressure of the gas phase substances in the upper half of the container. , which in turn affects the changes in air pressure inside the container;
如前所述，容器内配置气体压力传感器(Pn),用于感知该单元容器内部气体压力变化；As mentioned before, a gas pressure sensor (Pn) is installed in the container to sense changes in gas pressure inside the unit container;
当气压传感器检测到容器内实时压力(Pn)与设定压力上限值(Ph)接近到一定范围内时，则系统判断容器内压力偏大，需进行抽气降压；则会打开排气阀门，抽取气体，降低容器内压力；When the air pressure sensor detects that the real-time pressure (Pn) in the container and the set pressure upper limit (Ph) are close to a certain range, the system determines that the pressure in the container is too high and needs to be pumped to reduce the pressure; it will open the exhaust Valve, extract gas and reduce the pressure in the container;
当排气进行一定量后，气压传感器检测到容器内实时压力(Pn)与设定压力下限值接近到一定范围时，则系统判断容器内压力合适，停止排气，关闭阀门；After exhausting for a certain amount, the air pressure sensor detects that the real-time pressure (Pn) in the container is close to the lower limit of the set pressure to a certain range, and the system determines that the pressure in the container is appropriate, stops exhausting, and closes the valve;
单元的密闭容器内，在污水挥发效应与系统根据压力变化进行排气的主动干预下，容器内气体压力大致呈现波动形态；In the closed container of the unit, under the active intervention of the volatilization effect of sewage and the system's exhaust according to pressure changes, the gas pressure in the container generally fluctuates;
对于废气产生量大的B类单元，废气收集原理如下：For Class B units that generate large amounts of waste gas, the waste gas collection principle is as follows:
相对于A类单元，就废气而言B类单元最大的不同在于废气来源主要不是源自液体挥发，而是污水处理工艺中需进行主动供气进入污水处理单元，因此产生的废气量大，且因单元内是主动供气，所以废气收集配置相对供气能力要为强大的的气体抽取能力，以保证单元内在供气、抽气同步进行情况下维持微弱负压状态；Compared with Class A units, the biggest difference in the waste gas of Class B units is that the source of waste gas is not mainly from liquid volatilization, but the active air supply into the sewage treatment unit is required in the sewage treatment process, so the amount of waste gas generated is large, and Since the unit is actively supplied with air, the exhaust gas collection configuration must have a strong gas extraction capacity relative to the air supply capacity to ensure that the unit maintains a weak negative pressure state when the air supply and extraction are synchronized;
B类单元(Ubn)中配置气压传感器(Pbn)；The Class B unit (Ubn) is equipped with a pressure sensor (Pbn);
定义通过进气口进入单元的气体流速为Vbi,定义通过出气口抽取到C单元的气流速度为Vbo；Define the gas flow rate entering the unit through the air inlet as Vbi, and define the air flow rate extracted to unit C through the air outlet as Vbo;
状态1：当气压传感器检测到容器内气压Pbn<P0,且|Pbn-P0|<a，即a为一自定义常数，表示为两个气压值的差值范围时，系统控制Vbo＝Vbi即可，也就是说，此时单元容器内，维持合理负压状态，则抽气速度与进气速度保持一致，尽量维持系统工作在这个状态；State 1: When the air pressure sensor detects the air pressure in the container Pbn < P0, and |Pbn-P0| < a, that is, a is a custom constant, expressed as the difference range of two air pressure values, the system controls Vbo = Vbi, that is Yes, that is to say, if a reasonable negative pressure is maintained in the unit container at this time, the air extraction speed will be consistent with the air intake speed, and the system will be kept in this state as much as possible;
状态2：当气压传感器检测到容器内气压：Pbn>＝P0时，此时容器内外气压相等，或者内压大于外部环境气压，系统调整运行状态，使得Vbo>Vbi；即增大出气速度，加大抽气力度，尽快达到Pbn<P0,且|Pbn-P0|<a的状态；State 2: When the air pressure sensor detects the air pressure in the container: Pbn>=P0, the air pressure inside and outside the container is equal, or the internal pressure is greater than the external ambient air pressure. The system adjusts the operating state so that Vbo>Vbi; that is, the air outlet speed is increased, and the air pressure inside the container is increased. Use high pumping force to reach the state where Pbn<P0 and |Pbn-P0|<a as soon as possible;
C类单元由三部分构成：废气与气溶胶负压收集子系统、废气消毒处理子系统、管路与阀，气与气溶胶收集的动力发生机构是“气体操作装置”，根据实际上处理量的需求，气体操作装置可能配置一组以上。Class C unit consists of three parts: exhaust gas and aerosol negative pressure collection subsystem, exhaust gas disinfection treatment subsystem, pipelines and valves. The power generating mechanism for gas and aerosol collection is a "gas operating device". According to the actual processing volume Depending on the needs, the gas operating device may be configured with more than one set.
气体操作装置产生动力，用于将特定容器内的气体通过物理手段转移到“废气消毒处理专用设备”，在废气消毒处理专用设备内通过化学、或者电、热、光、化学方法与物理吸附方法的综合应用对废气与气溶胶进行消毒、杀菌，确保废气与气溶胶中可能存在的病毒被灭杀；The gas operating device generates power and is used to transfer the gas in a specific container to "special equipment for waste gas disinfection treatment" through physical means. In the special equipment for waste gas disinfection treatment, it uses chemical, or electricity, heat, light, chemical methods and physical adsorption methods. The comprehensive application of disinfection and sterilization of exhaust gas and aerosols ensures that viruses that may be present in exhaust gases and aerosols are killed;
废气与气溶胶负压收集子系统针对A类、B类单元废气产生机理、废气量的不同，设置两类管路；The exhaust gas and aerosol negative pressure collection subsystem is equipped with two types of pipelines based on the different exhaust gas generation mechanisms and exhaust gas volumes of Class A and Class B units;
A类单元气量少，主要源自挥发，则A类单元并联在一条管路上，每个单元通过阀(Fa1,Fa2,Fa…,Fan)与管路连接，管路另一端与气体操作装置连接，在检测到某单元(Fan)内部气体压力触发气体抽取设定值，即上述压力上限值(Ph)时，则打开该容器对应的阀门Fan，并启动气体操作装置进行抽气操作，抽气过程中，持续检测Fan内压力值(Pan)，待压力值降低到设定值(Pa l)时，关闭阀门，停止抽气；Class A units have small gas volume, mainly due to volatilization, so Class A units are connected in parallel on a pipeline. Each unit is connected to the pipeline through a valve (Fa1, Fa2, Fa..., Fan), and the other end of the pipeline is connected to the gas operating device. , when the internal gas pressure of a certain unit (Fan) is detected to trigger the gas extraction set value, that is, the above-mentioned pressure upper limit value (Ph), the valve Fan corresponding to the container is opened, and the gas operating device is started to perform the gas extraction operation. During the gas pumping process, the pressure value (Pan) inside the fan is continuously detected. When the pressure value drops to the set value (Pa l), the valve is closed and the pumping is stopped;
A类单元内部主动供气，气量大，则需要气体操作装置持续操作，要求抽气量略大于供气量，正常情况下阀门Pbn处于常开状态。There is an active air supply inside the Class A unit. If the air volume is large, the gas operating device needs to be continuously operated. The air extraction volume is required to be slightly larger than the air supply volume. Under normal circumstances, the valve Pbn is in a normally open state.

No more than 24 hours. For the treatment of infectious hospital sewage (epidemic sewage), pre-disinfection is a process that requires priority treatment. The disinfected sewage enters the pretreatment unit; the ordinary sewage from general hospitals is collected by the pipe network and directly enters the pretreatment unit;
预处理单元：综合医院普通污水与传染病医院污水(疫情污水)经预消毒处理后的污水导入预处理单元。本工艺阶段，污水初步实现有机物散化，大块无机物、塑料等不能生化处理物质实现第一次分离；Pretreatment unit: The sewage from general hospitals and infectious disease hospital sewage (epidemic sewage) that has been pre-disinfected is introduced into the pretreatment unit.

物理安全冗余单元：在特定情况下，渣液分离单元分离出来的污水进入物理安全冗余单元。特定情况是指“水量平抑单元”以及之后工艺环节故障不能运行。在此意外情况下，为确保前端医疗工作一定时间内(6小时、24小时等)产生的污水能安全存放在此处。在系统正常工作后，物理安全冗余单元内存储的污水应尽快转移到“水量平抑单元”，进行后续处理。物理安全冗余单元在正常工作状态下，应尽可能保持空置状态。在实际应用中，预处理单元；Physical security redundant unit: Under certain circumstances, the sewage separated by the slag-liquid separation unit enters the physical security redundant unit. The specific situation refers to the failure of the "water volume stabilization unit" and subsequent process links to fail to operate. In this unexpected situation, in order to ensure that the sewage generated by the front-end medical work within a certain period of time (6 hours, 24 hours, etc.) can be safely stored here. After the system is in normal operation, the sewage stored in the physical security redundant unit should be transferred to the "water volume stabilization unit" as soon as possible for subsequent processing. Physical security redundant units should remain vacant as much as possible under normal operating conditions. In practical applications, preprocessing units;
生化处理单元：从水量平抑单元流出的污水进入生化处理单元，生化处理单元进行污水的生化降解处理。该单元真正进行污水中污染物的消除、降解工作，并确保出水到达排放标准。该工艺环节内实现大量基于传统污水处理方法，如AO、AAO等具体工艺方法与实现；Biochemical treatment unit: The sewage flowing out from the water volume stabilization unit enters the biochemical treatment unit, and the biochemical treatment unit performs biochemical degradation treatment of the sewage. This unit truly eliminates and degrades pollutants in sewage and ensures that the effluent meets discharge standards. A large number of specific process methods and implementations based on traditional sewage treatment methods, such as AO and AAO, are implemented in this process link;
生化处理单元处理完的污水进入泥液分离单元，泥液分离单元完成生化处理后污水、污泥分离；该工艺具体实现方法多数基于物理沉降方式，也有采用膜过滤方式来实现泥水分离。分离后的污水进入水消毒单元，污泥则进入泥无害化处理单元；The sewage treated by the biochemical treatment unit enters the mud-liquid separation unit. After the mud-liquid separation unit completes the biochemical treatment, the sewage and sludge are separated. Most of the specific implementation methods of this process are based on physical sedimentation, and membrane filtration is also used to achieve mud-water separation. The separated sewage enters the water disinfection unit, and the sludge enters the mud harmless treatment unit;
污水进入水消毒单元后，按照既定方式完成消毒，实现无害化、水质达标排放；After the sewage enters the water disinfection unit, it is disinfected according to the established method to achieve harmless discharge and water quality standards;
污泥进入无害化处理单元后，按照既定方法进行消毒，实现污泥无害化。如系统不配置污泥深度处理，则污泥暂存在本环节，后续专业服务清掏处理。如配置污泥深度处理单元，则将污泥排入污泥深度处理单元；After the sludge enters the harmless treatment unit, it is disinfected according to established methods to achieve harmless sludge. If the system is not equipped with advanced sludge treatment, the sludge will be temporarily stored in this link and will be cleared and processed by subsequent professional services. If an advanced sludge treatment unit is configured, discharge the sludge into the advanced sludge treatment unit;
污泥深度处理单元内对污泥进行干化、封包处理，以便后续清运工作进行；The sludge is dried and packaged in the advanced sludge treatment unit for subsequent cleaning and transportation;
预消毒单元、预处理单元、渣液分离单元、水量平抑单元、物理安全冗余单元、生化处理单元、泥液分离、污泥无害化处理单元中，均有废气产生。各环节废气统一收集到废气处理单元。废气处理单元对废气进行除臭、无害化处理后排出；Waste gas is generated in the pre-disinfection unit, pre-treatment unit, slag-liquid separation unit, water volume stabilization unit, physical safety redundancy unit, biochemical treatment unit, mud-liquid separation, and sludge harmless treatment unit. The waste gas from each link is collected uniformly into the waste gas treatment unit. The exhaust gas treatment unit deodorizes and harmlessly treats the exhaust gas and then discharges it;
药剂配给单元则内置各种药剂，以及输送药剂的泵阀机构，通过药剂配送管道将药剂送入预消毒单元、污泥无害化处理单元、废气无害化处理单元、水消毒单元，满足各功能单元中药剂需求；The pharmaceutical distribution unit has built-in various pharmaceuticals, as well as a pump and valve mechanism for transporting pharmaceuticals.

Pharmaceutical requirements in functional units;

It is used to ration power and wind (oxygen) to each unit, and to quantitatively and based on the perception of the unit's operating process and results. The result is the execution of a specific institutional action;
根据污水处理的实际情况，各单元可相对独立部署，也可在满足安全、达标排水的基础上进行部分单元的合并与简化部署。现在绝大多数医疗卫生机构通常只部署其中的5、7、8、9、11几个单元；According to the actual situation of sewage treatment, each unit can be deployed relatively independently, or some units can be merged and simplified on the basis of ensuring safe and up-to-standard drainage. Nowadays, most medical and health institutions usually only deploy units 5, 7, 8, 9, and 11;
2、整个处理系统中，除药剂配给、电控与动力单元外，其他污水处理单元均与废气(气溶胶)有关。这些与废气(气溶胶)相关单元中(单元1～12)，废气处理单元(单元10)是收集、处理其他单元(单元1、2、3、4、5、6、7、8、9、11、12)中产生的废气的功能单元，确保整个系统运行中伴生的气(气溶胶)排放可控、无害化。2. In the entire treatment system, except for the chemical distribution, electronic control and power units, other sewage treatment units are related to waste gas (aerosol). Among these exhaust gas (aerosol)-related units (units 1 to 12), the exhaust gas treatment unit (unit 10) collects and processes other units (units 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12) The functional unit of the waste gas generated in the system ensures that the gas (aerosol) emissions associated with the operation of the entire system are controllable and harmless.
3、实际上医疗污水处理中伴生气(气溶胶)处理单元，具体包括三类功能子单元。3. In fact, the associated gas (aerosol) treatment unit in medical sewage treatment specifically includes three types of functional sub-units.
整体医疗污水处理系统中各单元依照从废气(气溶胶)产生机理、气量、处理角度，伴生废气(气溶胶)的单元分为：Each unit in the overall medical sewage treatment system is divided into units that produce waste gas (aerosol) based on the waste gas (aerosol) generation mechanism, gas volume, and treatment perspective:
A类：废气主要源自污水挥发，气量产生较少的单元，主要包括单元1、2、3、4、5、6、8、9、11、12。图2中，这类单元表示为Uan。Category A: The waste gas mainly comes from the volatilization of sewage and the units that produce less gas, mainly including units 1, 2, 3, 4, 5, 6, 8, 9, 11, and 12. In Figure 2, this type of unit is represented as Uan.
B类：废气主要源自污水处理特定工艺段需要的主动曝气(动力系统主动通风供氧)，产生大量气体的单元，主要是生化处理单元(单元7)。图2中，这类单元表示为Ubn。Category B: Waste gas mainly originates from active aeration (active ventilation and oxygen supply of power system) required in specific process sections of sewage treatment. Units that produce a large amount of gas are mainly biochemical treatment units (Unit 7). In Figure 2, this type of unit is represented as Ubn.
C类：不产生废气，收集其他单元产生的废气，并进行处理的单元(单元10)。图2中，这类单元表示为Ucn。Category C: A unit that does not produce waste gas but collects waste gas generated by other units and processes it (unit 10). In Figure 2, this type of unit is represented as Ucn.
4、本专利所述医疗污水处理的单元，容积上依照污水处理量进行配置，但各单元结构上均为(可)密闭容器。上述A类、B类单元中容器内部配置液位传感器与气压传感器(Pn)。4. The medical sewage treatment unit described in this patent is configured in volume according to the sewage treatment capacity, but each unit is a (possibly) sealed container in structure. The above-mentioned type A and type B units are equipped with a liquid level sensor and a pressure sensor (Pn) inside the container.
该容器结构上除配置该单元特定处理物质(污水、渣、泥)的正常可控进、出口(阀、管道)外，容器上部配置2路气体进出口。容器上留出的气体进出口(管道)均配置可控阀。其中一路作为备用调压口，实现容器内部与特定压力环境的连通。这个特定气压环境实际上构成整个系统中的基准参考气压。这路气体通道默认状态时关闭的，在特定情况下比如容器内部压力环境出现超设定、无法平衡的偏差后，开启此通道以恢复容器内部压力环境。In addition to the normal controllable inlet and outlet (valves, pipes) of the unit's specific treatment materials (sewage, slag, mud), the upper part of the container is equipped with 2 gas inlets and outlets. The gas inlet and outlet (pipeline) left on the container are equipped with controllable valves. One of them serves as a backup pressure regulating port to connect the inside of the container to a specific pressure environment. This specific air pressure environment actually constitutes the base reference air pressure in the entire system. This gas channel is closed by default. Under certain circumstances, such as when the internal pressure environment of the container deviates beyond the set value and cannot be balanced, this channel can be opened to restore the internal pressure environment of the container.
另外一路是容器内部气体抽取通道，当压力传感器感知到容器内部压力超出预定范围后，就打开阀门，配合外部动力装置对容器内部气体抽取，维持容器内部气体压力在一定范围。The other path is the gas extraction channel inside the container. When the pressure sensor senses that the pressure inside the container exceeds a predetermined range, it opens the valve and cooperates with the external power device to extract the gas inside the container to maintain the gas pressure inside the container within a certain range.
5、对于废气产生量较小的A类单元，废气产生、收集原理如图4下。5. For Class A units with small waste gas generation, the principle of waste gas generation and collection is as shown in Figure 4.
A类单元在正常工作进行污水处理时，内部呈现气液双相形态；且液体水因挥发或其他原因会持续转化成为气态，改变容器内上半部分空间的气相物质的成份与气压等物理性质，进而影响到容器内气压的变化。When a Class A unit is operating normally for sewage treatment, the interior will be in a gas-liquid two-phase state; and the liquid water will continue to transform into a gaseous state due to volatilization or other reasons, changing the composition and pressure of the gas phase substances in the upper half of the container. , which in turn affects the changes in air pressure inside the container.
如前所述，容器内配置气体压力传感器(Pn),用于感知该单元容器内部气体压力变化。As mentioned before, a gas pressure sensor (Pn) is installed in the container to sense changes in gas pressure inside the unit container.
当气压传感器检测到容器内实时压力(Pn)与设定压力上限值(Ph)接近到一定范围内时，则系统判断容器内压力偏大，需进行抽气降压。则会打开排气阀门，抽取气体，降低容器内压力。When the air pressure sensor detects that the real-time pressure (Pn) in the container and the set pressure upper limit (Ph) are close to a certain range, the system determines that the pressure in the container is too high and needs to be pumped to reduce the pressure. The exhaust valve will be opened to extract gas and reduce the pressure in the container.
当排气进行一定量后，气压传感器检测到容器内实时压力(Pn)与设定压力下限值接近到一定范围时，则系统判断容器内压力合适，停止排气，关闭阀门。After exhausting for a certain amount, the air pressure sensor detects that the real-time pressure (Pn) in the container is close to the lower limit of the set pressure to a certain range, then the system determines that the pressure in the container is appropriate, stops exhausting, and closes the valve.
单元的密闭容器内，在污水挥发效应与系统根据压力变化进行排气的主动干预下，容器内气体压力大致呈现波动形态(如图3)。In the closed container of the unit, under the active intervention of the volatilization effect of sewage and the system's exhaust according to pressure changes, the gas pressure in the container generally fluctuates (Figure 3).
6、对于废气产生量大的B类单元，废气收集原理如下：6. For Class B units that generate large amounts of waste gas, the waste gas collection principle is as follows:
相对于A类单元，就废气而言B类单元最大的不同在于废气来源主要不是源自液体挥发，而是污水处理工艺中需进行主动供气进入污水处理单元。因此产生的废气量大，且因单元内是主动供气，所以废气收集配置相对供气能力要为强大的的气体抽取能力，以保证单元内在供气、抽气同步进行情况下维持微弱负压状态。Compared with Class A units, the biggest difference in Class B units in terms of exhaust gas is that the source of exhaust gas is not mainly from liquid volatilization, but requires active air supply into the sewage treatment unit during the sewage treatment process. Therefore, the amount of waste gas generated is large, and because the unit is actively supplied with air, the waste gas collection configuration must have a strong gas extraction capacity relative to the gas supply capacity to ensure that the unit maintains a weak negative pressure when the gas supply and extraction are synchronized. state.
B类单元(Ubn)中配置气压传感器(Pbn)。The type B unit (Ubn) is equipped with a pressure sensor (Pbn).
定义通过进气口进入单元的气体流速为Vbi,定义通过出气口抽取到C单元的气流速度为Vbo。Define the gas flow rate entering the unit through the air inlet as Vbi, and define the air flow rate extracted to unit C through the air outlet as Vbo.
状态1：当气压传感器检测到容器内气压Pbn<P0,且|Pbn-P0|<a(a为一自定义常数，表示为两个气压值的差值范围)时，系统控制Vbo＝Vbi即可。也就是说，此时单元容器内，维持合理负压状态，则抽气速度与进气速度保持一致，尽量维持系统工作在这个状态。State 1: When the air pressure sensor detects the air pressure in the container Pbn < P0, and |Pbn-P0| < a (a is a custom constant, expressed as the difference range of two air pressure values), the system controls Vbo = Vbi, that is Can. In other words, if a reasonable negative pressure is maintained in the unit container at this time, the air extraction speed will be consistent with the air intake speed, and the system will be kept in this state as much as possible.
状态2：当气压传感器检测到容器内气压：Pbn>＝P0时(此时容器内外气压相等，或者内压大于外部环境气压)，系统调整运行状态，使得Vbo>Vbi。即增大出气速度，加大抽气力度，尽快达到Pbn<P0,且|Pbn-P0|<a的状态。State 2: When the air pressure sensor detects the air pressure in the container: Pbn>=P0 (at this time, the air pressure inside and outside the container is equal, or the internal pressure is greater than the external ambient air pressure), the system adjusts the operating state so that Vbo>Vbi. That is, increase the air outlet speed, increase the air pumping intensity, and reach the state of Pbn<P0 and |Pbn-P0|<a as soon as possible.
6、C类单元(图1中用Ucn代表)由三部分构成：废气与气溶胶负压收集子系统、废气消毒处理子系统、管路与阀。6. Class C unit (represented by Ucn in Figure 1) consists of three parts: exhaust gas and aerosol negative pressure collection subsystem, exhaust gas disinfection treatment subsystem, pipelines and valves.
废气与气溶胶收集的动力发生机构是“气体操作装置”，根据实际上处理量的需求，气体操作装置可能配置一组以上。The power generation mechanism for waste gas and aerosol collection is a "gas operating device". Depending on the actual processing capacity requirements, more than one set of gas operating devices may be configured.
气体操作装置产生动力，用于将特定容器内的气体通过物理手段转移到“废气消毒处理专用设备”。在废气消毒处理专用设备内通过化学、或者电、热、光、化学方法与物理吸附方法的综合应用对废气与气溶胶进行消毒、杀菌，确保废气与气溶胶中可能存在的病毒被灭杀。The gas operating device generates power and is used to physically transfer the gas in a specific container to "special equipment for waste gas disinfection treatment". In special equipment for waste gas disinfection treatment, waste gas and aerosols are disinfected and sterilized through the comprehensive application of chemistry, electricity, heat, light, chemical methods and physical adsorption methods to ensure that viruses that may be present in waste gas and aerosols are killed.
废气与气溶胶负压收集子系统针对A类、B类单元废气产生机理、废气量的不同，设置两类管路。The exhaust gas and aerosol negative pressure collection subsystem is equipped with two types of pipelines based on the different exhaust gas generation mechanisms and exhaust gas volumes of Class A and Class B units.
A类单元气量少，主要源自挥发。则A类单元并联在一条管路上，每个单元通过阀(Fa1,Fa2,Fa…,Fan)与管路连接。管路另一端与气体操作装置连接。在检测到某单元(Fan)内部气体压力触发气体抽取设定值(上述压力上限值：Ph)时，则打开该容器对应的阀门Fan，并启动气体操作装置进行抽气操作。抽气过程中，持续检测Fan内压力值(Pan)，待压力值降低到设定值(Pa l)时，关闭阀门，停止抽气。Class A units have less gas volume, mainly due to volatilization. Then Class A units are connected in parallel on a pipeline, and each unit is connected to the pipeline through valves (Fa1, Fa2, Fa..., Fan). The other end of the pipeline is connected to the gas operating device. When the internal gas pressure of a certain unit (Fan) is detected to trigger the gas extraction set value (the above-mentioned pressure upper limit value: Ph), the valve Fan corresponding to the container is opened, and the gas operating device is started to perform the gas extraction operation. During the pumping process, the pressure value (Pan) inside the fan is continuously detected. When the pressure value drops to the set value (Pa l), the valve is closed and the pumping is stopped.
A类单元内部主动供气，气量大，则需要气体操作装置持续操作，要求抽气量略大于供气量。正常情况下阀门Pbn处于常开状态。There is an active air supply inside the Class A unit. If the air volume is large, the gas operating device needs to be continuously operated, and the air extraction volume is required to be slightly larger than the air supply volume. Under normal circumstances, valve Pbn is in a normally open state.
