技术领域technical field
本发明涉及一种高温余热回收装置，属于工业高温余热回收与节能技术领域。The invention relates to a high-temperature waste heat recovery device, which belongs to the technical field of industrial high-temperature waste heat recovery and energy saving.
背景技术Background technique
在电石、石墨化和金属冶炼等工业生产中，产出的物料产品均具有较高温度。例如，目前常用的石墨提纯设备为艾奇逊炉和串接石墨化炉。石墨化生产过程中，需要电加热方式将待石墨化产品加热至3000℃，且需要加热17-48小时才能完成石墨提纯。此时，保温料表面平均温度可达1700℃，如采用自然冷却方式，约需10天才能完成冷却。电石炉是另一种产出高温物料的工业用炉，在其生产过程中，电石出炉温度为1800-2000℃，经过自然冷却至60-80℃后，用吊车将电石移至库房进行堆积处理。这给工业生产带来的问题是：一是自然冷却降温周期较长，影响生产效率；二是大量高温余热被浪费。In industrial production such as calcium carbide, graphitization and metal smelting, the output materials and products all have relatively high temperatures. For example, the currently commonly used graphite purification equipment is Acheson furnace and serial graphitization furnace. During the graphitization production process, electric heating is required to heat the product to be graphitized to 3000°C, and it takes 17-48 hours to complete the graphite purification. At this time, the average surface temperature of the insulation material can reach 1700°C. If the natural cooling method is adopted, it will take about 10 days to complete the cooling. Calcium carbide furnace is another industrial furnace that produces high-temperature materials. During its production process, the calcium carbide furnace is released at a temperature of 1800-2000°C. After natural cooling to 60-80°C, the calcium carbide furnace is moved to the warehouse for stacking by a crane. . The problems that this brings to industrial production are: first, the cooling cycle of natural cooling is long, which affects production efficiency; second, a large amount of high-temperature waste heat is wasted.
现有技术中，在工业生产的余热回收方面，中国专利文献CN201420177764.3、CN201610259982.5和CN201520441390.5公开了采用空气回收余热的装置。其中，文献CN201420177764.3公开的是一种石墨化炉余热回收发电供热系统，该系统将冷却盘管置于石墨化炉内，进行余热回收，该方案不适用于现有炉型的改造升级，且所采用的空气载热能力差、冷却效率低、回收热量不稳定，影响余热的再利用。文献CN201520441390.5公开了一种熔融电石余热回收系统，通过输送空气将电石高温表面进行热交换，使用气-水换热器达到余热回收目的。文献CN201610259982.5公开一种熔融电石余热回收的方法，通过控制风流量大小达到电石在强迫风冷过程中均匀放出热量的目的。上述技术均是以空气作为热量输运介质，冷却效率低；同时，受间歇式生产方式的限制，存在余热回收不稳定、余热再利用难的问题。In the prior art, in terms of waste heat recovery in industrial production, Chinese patent documents CN201420177764.3, CN201610259982.5 and CN201520441390.5 disclose devices that use air to recover waste heat. Among them, the document CN201420177764.3 discloses a graphitization furnace waste heat recovery power generation and heat supply system. In this system, the cooling coil is placed in the graphitization furnace for waste heat recovery. This scheme is not suitable for the transformation and upgrading of existing furnace types. , and the air used has poor heat carrying capacity, low cooling efficiency, and unstable heat recovery, which affects the reuse of waste heat. Document CN201520441390.5 discloses a waste heat recovery system for molten calcium carbide, which exchanges heat on the high-temperature surface of calcium carbide by conveying air, and uses an air-water heat exchanger to achieve the purpose of waste heat recovery. Document CN201610259982.5 discloses a method for recovering waste heat from molten calcium carbide, which achieves the purpose of uniformly releasing heat from calcium carbide in the process of forced air cooling by controlling the air flow rate. The above-mentioned technologies all use air as the heat transport medium, and the cooling efficiency is low. At the same time, due to the limitation of the intermittent production mode, there are problems of unstable waste heat recovery and difficult reuse of waste heat.

具体实施方式Detailed ways
下面结合附图和具体实施例对本发明的结构、工作原理和工艺过程进行详细阐述。The structure, working principle and technological process of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
如图1和2所示，本发明提供的一种周期性高温余热回收装置，其包括反射板1、辐射换热储热复合体2和高温热源面4；反射板1、辐射换热储热复合体2和高温热源面4围成一个辐射空腔3；所述的反射板1设置在辐射空腔3上面，辐射换热储热复合体2设置在辐射空腔3的周围；高温热源面4的下面放置高温物料12。所述的辐射换热储热复合体2由里向外依次包括金属吸热板5、吸热管6、金属导热板7、高温蓄热层8、低温隔热层9和保护层10；所述的金属导热板7、吸热管6和吸热板5紧密地接触；在吸热管6内充满载热工质，载热工质优选采用水。As shown in Figures 1 and 2, a periodic high-temperature waste heat recovery device provided by the present invention includes a reflector 1, a radiation heat exchange and heat storage complex 2, and a high-temperature heat source surface 4; the reflector 1, the radiation heat exchange and heat storage The complex 2 and the high-temperature heat source surface 4 form a radiation cavity 3; the reflector 1 is arranged on the radiation cavity 3, and the radiation heat exchange and heat storage complex 2 is arranged around the radiation cavity 3; the high-temperature heat source surface Place high-temperature material 12 below 4. The radiation heat exchange heat storage complex 2 sequentially includes a metal heat absorbing plate 5, a heat absorbing pipe 6, a metal heat conducting plate 7, a high temperature heat storage layer 8, a low temperature heat insulation layer 9 and a protective layer 10 from the inside to the outside; The metal heat conducting plate 7, the heat-absorbing pipe 6 and the heat-absorbing plate 5 are in close contact; the heat-absorbing pipe 6 is filled with a heat-carrying working medium, and the heat-carrying working medium is preferably water.
为了提高吸收热量的能力，在与辐射空腔3接触的吸热板5表面上涂有一层高发射率的涂层，高发射率涂层的发射率不低于0.8。例如高发射率涂层可选择碳化硅、三氧化二钴以及丙烯树脂、有机硅树脂等为基材的涂层等。所述的吸热板5和辐射空腔3接触的表面可制成凸凹粗糙面，以增加其吸热能力。In order to improve the ability to absorb heat, a layer of high-emissivity coating is coated on the surface of the heat-absorbing plate 5 in contact with the radiation cavity 3, and the emissivity of the high-emissivity coating is not lower than 0.8. For example, high-emissivity coatings can choose silicon carbide, dicobalt trioxide, acrylic resin, silicone resin, etc. as substrates. The contact surface of the heat absorbing plate 5 and the radiation cavity 3 can be made into a convex and concave rough surface to increase its heat absorbing capacity.
所述的反射板1是由多层金属板和金属板之间的空气夹层组成，所述的反射板1表面涂有低发射率涂层，低发射率涂层的发射率不高于0.3。其中低发射率涂层为无机氧化物或有机氧化物涂层，无机氧化物涂层如氧化锌、二氧化钛或二氧化锆等，有机氧化物涂层如有机硅和丙烯酸等。The reflector 1 is composed of multi-layer metal plates and an air interlayer between the metal plates. The surface of the reflector 1 is coated with a low-emissivity coating, and the emissivity of the low-emissivity coating is not higher than 0.3. The low-emissivity coating is inorganic oxide or organic oxide coating, inorganic oxide coating such as zinc oxide, titanium dioxide or zirconium dioxide, etc., organic oxide coating such as organic silicon and acrylic acid, etc.
所述的高温蓄热层8优选采用钢渣、高铝混凝土、三氧化二铝或卵石中的一种或几种作为蓄热材料。所述的保护层10可为铸钢；所述的低温储热层9可采用膨胀珍珠岩、硅酸铝制品等。The high-temperature heat storage layer 8 preferably uses one or more of steel slag, high-aluminum concrete, aluminum oxide or pebbles as heat storage materials. The protective layer 10 can be cast steel; the low-temperature heat storage layer 9 can be made of expanded perlite, aluminum silicate products and the like.
以冶炼完成后的高温物料为例，待冶炼完成时，物料的温度常常高于1700℃(即高温物料12)，此时高温物料12被放置在保温墙体11内。辐射换热储热复合体2将高温物料从四周围住，且本装置的反射板1将物料盖住，保证了物料及物料附近的热空气、灰尘不会向周围环境扩散。高温物料12的上面为高温热源面4，高温物料12通过高温热源面12向外传热。由于高温热源面4的温度较高，它将以热辐射和热对流的形式向包围高温物料的辐射换热储热复合体2以及顶部的反射板1进行传热。Take the high-temperature material after smelting as an example. When the smelting is completed, the temperature of the material is usually higher than 1700° C. (ie, the high-temperature material 12 ). At this time, the high-temperature material 12 is placed in the insulation wall 11 . The radiation heat exchange and heat storage complex 2 surrounds the high-temperature materials, and the reflector 1 of the device covers the materials, so as to ensure that the materials and the hot air and dust near the materials will not spread to the surrounding environment. The top of the high-temperature material 12 is a high-temperature heat source surface 4 , and the high-temperature material 12 conducts heat outward through the high-temperature heat source surface 12 . Due to the high temperature of the high-temperature heat source surface 4, it will transfer heat to the radiation heat exchange heat storage complex 2 surrounding the high-temperature material and the reflection plate 1 on the top in the form of heat radiation and heat convection.
由于辐射换热储热复合体2的发射率较高，它能几乎将辐射进来的80％以上的热量全部吸收掉。反射板1具有不高于0.3的低发射率涂层和空气隔热夹层。因此反射板1将其得到的总热量中的98％热量反射给辐射换热储热复合体2和高温热源面4，从而提高了辐射换热储热复合体2的辐射热流强度。结果是从高温热源面4辐射出来的热量源源不断地流向了辐射换热储热复合体2，有效强化了高温余热的热回收效率。Due to the high emissivity of the radiative heat exchange heat storage complex 2, it can almost completely absorb more than 80% of the radiated heat. The reflection plate 1 has a low-emissivity coating not higher than 0.3 and an air heat-insulating interlayer. Therefore, the reflecting plate 1 reflects 98% of the total heat obtained by it to the radiation heat exchange and heat storage complex 2 and the high-temperature heat source surface 4 , thereby increasing the radiation heat flow intensity of the radiation heat exchange and heat storage complex 2 . The result is that the heat radiated from the high-temperature heat source surface 4 continuously flows to the radiation heat exchange and heat storage complex 2, which effectively enhances the heat recovery efficiency of high-temperature waste heat.
同时，高温热源面以导热和对流的方式加热了与其接触的空气，热空气浮升力增加，使得热空气上升并与反射板1和辐射换热储热复合体2所接触的表面相互作用。由于辐射换热储热复合体2的温度相对较低，辐射换热储热复合体2不断对热空气进行冷却，导致辐射换热储热复合体2附近气流温度较低、密度较大，这使得冷空气不断下沉并返回至高温热源面4附近，冷空气再次被高温热源面加热。最终，空气在以高温热源面4为热源、以辐射换热储热复合体2为冷源的闭式系统中进行周期性循环流动，热量则以对流换热的形式从高温热源面4传递到辐射换热储热复合体2上，实现了热量由不断地高温热源4流向辐射换热储热复合体2迁移。At the same time, the high-temperature heat source surface heats the air in contact with it through heat conduction and convection, and the buoyancy of the hot air increases, making the hot air rise and interact with the surface in contact with the reflective plate 1 and the radiation heat exchange heat storage complex 2 . Since the temperature of the radiation heat exchange and heat storage complex 2 is relatively low, the radiation heat exchange and heat storage complex 2 continuously cools the hot air, resulting in lower temperature and higher density of the airflow near the radiation heat exchange and heat storage complex 2. The cold air continuously sinks and returns to the vicinity of the high-temperature heat source surface 4, and the cold air is heated by the high-temperature heat source surface again. Finally, the air circulates periodically in a closed system with the high-temperature heat source surface 4 as the heat source and the radiation heat exchange heat storage complex 2 as the cold source, and the heat is transferred from the high-temperature heat source surface 4 to the air in the form of convective heat exchange. On the radiative heat exchange heat storage complex 2 , heat transfer from the continuous high-temperature heat source 4 to the radiative heat exchange heat storage complex 2 is realized.
辐射换热储热复合体2接收到热量后，传递给与其接触的金属导热板7，金属导热板7上设置了凹槽7a，吸热管嵌在凹槽7a内，凹槽7a既实现了吸热管6的固定，同时又增加了金属导热板7和吸热管之间的传热面积，根据牛顿冷却公式，强化了辐射换热储热复合体2内的传热，金属板7对吸热管加热的同时，吸热管内的液体工质也被加热。在吸热管6载热工质被加热后，携带热量流出本装置，实现了高温余热的再利用。After the radiation heat exchange and heat storage complex 2 receives the heat, it transmits it to the metal heat conducting plate 7 in contact with it, and the metal heat conducting plate 7 is provided with a groove 7a, and the heat absorbing pipe is embedded in the groove 7a, and the groove 7a realizes The fixing of the heat-absorbing pipe 6 increases the heat transfer area between the metal heat-conducting plate 7 and the heat-absorbing pipe at the same time. According to Newton’s cooling formula, the heat transfer in the radiation heat exchange and heat storage complex 2 is strengthened. The metal plate 7 pairs When the heat-absorbing tube is heated, the liquid working medium in the heat-absorbing tube is also heated. After the heat-carrying working medium in the heat-absorbing pipe 6 is heated, it carries heat and flows out of the device, realizing the reuse of high-temperature waste heat.
在本装置启动阶段时，高温热源面4温度较高，因此传入辐射换热储热复合体2内的热量较多，金属导热板将多余的热量传递给高温蓄热层8进行蓄热，随着辐射和对流换热的进行，高温热源面4的温度逐渐降低，当高温物料完成冷却后，高温物料变成常温物料，此时常温物料将被转移走，此时，高温蓄热层承担着吸热管6内工质吸热的热源，实现了间断性高温热源余热的回收和持续稳定输出。此外，本装置设置的高温蓄热层8外部的低温隔热层9和保护层10能够有效地避免本装置向环境散热。During the start-up stage of the device, the temperature of the high-temperature heat source surface 4 is relatively high, so more heat is transferred into the radiation heat exchange and heat storage complex 2, and the metal heat conducting plate transfers excess heat to the high-temperature heat storage layer 8 for heat storage. With the progress of radiation and convective heat transfer, the temperature of the high-temperature heat source surface 4 gradually decreases. When the high-temperature material is cooled, the high-temperature material becomes a normal-temperature material. At this time, the normal-temperature material will be transferred away. At this time, the high-temperature heat storage layer bears The heat source of the working fluid in the heat-absorbing pipe 6 realizes the recovery of waste heat from the intermittent high-temperature heat source and continuous and stable output. In addition, the low-temperature thermal insulation layer 9 and protective layer 10 outside the high-temperature heat storage layer 8 provided in the device can effectively prevent the device from dissipating heat to the environment.
通过本装置回收的周期性高温余热，可用于持续稳定的工业用蒸汽、附近居民区冬季采暖等。The periodic high-temperature waste heat recovered by this device can be used for continuous and stable industrial steam, winter heating in nearby residential areas, etc.
