背景技术Background technique
焦化行业是关系国民经济命脉的重要产业，近年来发展迅速，但焦化生产所带来严重的环境污染问题也日渐突出。在焦炉生产过程中，装煤、推焦、出焦等生产环节会向大气中排放大量阵发性烟尘；炉门、炉顶装煤孔、看火孔等部位也会逸散无组织排放烟尘。烟尘内包含有焦油类物质的煤气和大量粉尘，对周边环境造成重大危害。The coking industry is an important industry related to the lifeline of the national economy. It has developed rapidly in recent years, but the serious environmental pollution problems caused by coking production have become increasingly prominent. During the coke oven production process, coal loading, coke pushing, coke extraction and other production links will emit large amounts of burst smoke into the atmosphere; unorganized emissions will also escape from the furnace door, furnace roof coal loading holes, fire viewing holes and other parts. Soot. The smoke contains gas containing tar-like substances and a large amount of dust, causing great harm to the surrounding environment.
目前焦化生产中，对装煤、推焦、出焦操作时排放的烟尘可以通过焦炉机械、炉头烟收集装置等配合对应的集尘干管进行收集，再送到对应的除尘地面站进行处理，但对逸散烟尘并没有很好的控制手段。随着国家对环保要求的不断提高，焦炉现有除尘技术已很难满足要求，只有不断发展先进、节能、高效的环保新工艺，才能积极推动焦化行业持续稳定的健康发展。At present, in coking production, the smoke and dust emitted during coal loading, coke pushing, and coke removal operations can be collected through coke oven machinery, burner smoke collection devices, etc. in conjunction with the corresponding dust collection trunk pipes, and then sent to the corresponding dust removal ground station for processing , but there is no good control method for escaping smoke and dust. As the country's environmental protection requirements continue to increase, it is difficult for the existing dust removal technology in coke ovens to meet the requirements. Only by continuously developing advanced, energy-saving, and efficient new environmentally friendly processes can we actively promote the sustainable, stable and healthy development of the coking industry.

本发明所述一种焦炉烟尘全封闭分散收集、集中处理装置的工作原理是(以顶装焦炉为例进行说明)：设置一个全封闭的烟尘收集罩1，将焦炉2及其附属设施如焦炉机械(包括炉顶装煤车5、机侧推焦机3及焦侧拦焦机4)、多个集尘干管17、18、19均置于该烟尘收集罩1内部，这样可以全面收集焦炉2生产过程中产生的烟尘。在烟尘收集罩1的顶部高点位置设逸散烟尘收集口6，通过烟尘输送管道9与除尘系统(除尘地面站10)连接，借助抽吸风机11的吸力将收集到的焦炉逸散烟尘送至除尘地面站10；同时，原有焦炉系统设置的装煤集尘干管17、推焦集尘干管18及出焦集尘干管19也连接烟尘输送管道9，即焦炉产生的所有烟尘最终均通过烟尘输送管道9送入除尘系统中，经集中净化处理后的净烟气达标排放。The working principle of a fully enclosed dispersed collection and centralized treatment device for coke oven smoke described in the present invention is (taking a top-mounted coke oven as an example): a fully enclosed smoke collection cover 1 is provided, and the coke oven 2 and its accessories are Facilities such as coke oven machinery (including furnace top coal loading car 5, machine side coke pusher 3 and coke side coke blocker 4) and multiple dust collection main pipes 17, 18, 19 are placed inside the smoke collection hood 1. In this way, the smoke and dust generated during the production process of coke oven 2 can be comprehensively collected. An escaping smoke collection port 6 is provided at the top high point of the smoke collection hood 1. It is connected to the dust removal system (dust removal ground station 10) through the smoke transport pipe 9. The collected coke oven escaping smoke is collected by the suction of the suction fan 11. sent to the dust removal ground station 10; at the same time, the coal loading dust collection main pipe 17, coke pushing dust collection main pipe 18 and coke discharge dust collection main pipe 19 set up in the original coke oven system are also connected to the smoke and dust transportation pipe 9, that is, the coke oven generates All the smoke and dust are finally sent to the dust removal system through the smoke and dust conveying pipe 9, and the clean flue gas after centralized purification is discharged up to the standard.
烟尘收集罩1为全封闭结构，采用钢结构骨架，外部设围护系统，其中屋面板和墙面板可采用彩钢板或采光板，在局部温度较高部位，钢结构骨架需涂耐高温漆并外包耐火陶瓷纤维或其它耐高温隔热材料。The smoke collection hood 1 is a fully enclosed structure, using a steel structure skeleton with an external enclosure system. The roof panels and wall panels can be made of color steel plates or lighting panels. In parts with higher local temperatures, the steel structure skeleton needs to be coated with high-temperature resistant paint and Wrapped with refractory ceramic fiber or other high temperature resistant insulation materials.
焦炉2正常生产时，炉门、炉顶装煤孔、看火孔等部位逸散的烟尘由逸散烟尘收集口6收集，装煤作业时产生的烟尘由装煤集尘系统收集到装煤集尘干管17中，推焦作业时产生的烟尘由推焦集尘系统收集到推焦集尘干管18中，出焦作业时产生的烟尘由出焦集尘系统收集到出焦集尘干管19中，这3个集尘干管17、18、19中的烟尘分别通过对应的连接管8进入到烟尘输送管道9中，然后所有收集到的烟尘统一进入除尘地面站10，经过净化后从烟囱排入大气中。抽吸风机11采用变频控制形式，其转速可以根据烟尘发生量进行实时调节，以实现节能降耗的目的。When the coke oven 2 is in normal production, the smoke and dust emitted from the furnace door, the coal loading hole on the top of the furnace, the fire sight hole and other parts are collected by the fugitive dust collection port 6. The smoke and dust generated during the coal loading operation are collected by the coal loading dust collection system In the coal dust collection main pipe 17, the smoke and dust generated during the coke pushing operation are collected by the coke pushing dust collection system into the coke pushing dust collection main pipe 18, and the smoke and dust generated during the coke removal operation are collected by the coke removal dust collection system to the coke removal collection system. In the dust main pipe 19, the smoke in the three dust collecting main pipes 17, 18, and 19 enters the smoke conveying pipe 9 through the corresponding connecting pipe 8, and then all the collected smoke enters the dust removal ground station 10 uniformly. After purification, it is discharged into the atmosphere from the chimney. The suction fan 11 adopts frequency conversion control, and its rotation speed can be adjusted in real time according to the amount of smoke and dust generated to achieve the purpose of energy saving and consumption reduction.
在烟尘收集罩1的四周设有多个反吹风口15，反吹风机16定期启动自反吹风口15向烟尘收集罩1内鼓入新鲜空气，使焦炉区域保持良好的通风状况，并改善焦炉区域的作业环境。事故状态下，焦炉区域放散的荒煤气会聚集在焦炉区域无法外排，造成重大安全隐患，此时如供电正常，反吹风机15会立即启动，通过向烟尘收集罩1内鼓入大量的空气将可燃组分浓度降低到爆炸极限以下；如此时处于停电情况下，反吹风机16可以在柴油发电机的驱动下继续工作。此外，在烟尘收集罩1的顶部还设置了多个自力式风帽12，在事故状态下可以与反吹风机16实现同步开启，辅助反吹风机16将烟尘收集罩1内的荒煤气放散至其外部。A plurality of back-blowing air vents 15 are provided around the smoke collection hood 1. The back-blowing fan 16 is regularly started to blow fresh air into the smoke collection hood 1 from the back-blowing air openings 15, so as to maintain good ventilation in the coke oven area and improve coking. The working environment in the furnace area. In the event of an accident, the waste gas emitted from the coke oven area will gather in the coke oven area and cannot be discharged, causing a major safety hazard. At this time, if the power supply is normal, the back blower 15 will start immediately and blow a large amount of gas into the smoke collection hood 1. The air reduces the concentration of flammable components below the explosion limit; if there is a power outage at this time, the back blower 16 can continue to work driven by the diesel generator. In addition, a plurality of self-operated wind caps 12 are provided on the top of the smoke collection hood 1, which can be turned on synchronously with the back blower 16 in an accident state, and the auxiliary back blow fan 16 can release the waste gas in the smoke collection hood 1 to the outside.
在事故状态下，焦炉2原有的荒煤气自动放散点火装置应自动开启进行荒煤气放散，但实际生产中点火装置有时不能及时响应，荒煤气压力过高时会将焦炉上升管13的水封盖顶开，荒煤气燃烧的火焰和高温将会直接炙烧烟尘收集罩1，对其造成毁灭性损害；为此，本发明在焦炉上升管13的上方加设导火装置14，导火装置14与焦炉上升管13一一对应设置，导火装置14的入口位于焦炉上升管13的正上方，出口高于烟尘收集罩1的顶面；当荒煤气自动放散而点火装置失灵时，导火装置14可与焦炉上升管13的水封盖同步开启，将荒煤气导出并外排至大气中，以达到保护烟尘收集罩1的目的。In the event of an accident, the original automatic waste gas release ignition device of the coke oven 2 should be automatically turned on to release the waste gas. However, in actual production, the ignition device sometimes cannot respond in time. When the waste gas pressure is too high, the coke oven riser pipe 13 will be damaged. When the water seal cover is opened, the flame and high temperature of the raw gas combustion will directly burn the smoke collection cover 1, causing devastating damage to it. For this reason, the present invention adds a fire guide 14 above the coke oven riser 13. The ignition device 14 is arranged in a one-to-one correspondence with the coke oven rising pipe 13. The inlet of the ignition device 14 is located directly above the coke oven rising pipe 13, and the outlet is higher than the top surface of the smoke collection hood 1; when the waste gas is automatically released, the ignition device When it fails, the ignition device 14 can be opened synchronously with the water sealing cover of the coke oven riser 13 to lead out the waste gas and discharge it into the atmosphere to achieve the purpose of protecting the smoke collection hood 1 .
烟尘收集罩1内设置有消防装置用于迅速熄灭事故状态下焦炉区域出现的明火；另外，烟尘收集罩1内还设有可燃及有毒气体检测报警装置，当烟尘收集罩1内的可燃及有毒气体达到浓度上限时，通过报警器发出警示提醒相关作业人员进行处理或者及时撤离，从而确保作业人员的人身安全。The smoke collection hood 1 is equipped with a fire-fighting device to quickly extinguish open flames in the coke oven area during accidents; in addition, the smoke collection hood 1 is also equipped with a flammable and toxic gas detection alarm device. When the flammable and toxic gases in the smoke collection hood 1 When the concentration of toxic gases reaches the upper limit, a warning will be issued through the alarm to remind relevant workers to deal with it or evacuate in time, thereby ensuring the personal safety of workers.
