Description
技术领域technical field
本发明涉及工业废气处理设备，具体说是一种可清洗粉尘和颗粒、并有效减少有害气体分子含量的工业用废气清洗器。The invention relates to industrial waste gas treatment equipment, in particular to an industrial waste gas cleaner which can clean dust and particles and effectively reduce the content of harmful gas molecules.
背景技术Background technique
随着我国工业化程度的逐步提高，工厂在日常生产中排放的废旧物料日益增多，因而其对周围环境的污染也越来越严重。在工厂的排放物中，废气是主要的污染源之一，特别是如水泥厂、铸造厂或饲料厂等企业，其排放的废气中含有大量的颗粒、粉尘或重金属碎屑等。为减少工厂废气对环境的影响，现有的工业厂房一般都会设置空气净化装置，其目的是减少空气中有害物质的含量，使从厂房内排放的空气不会对周围环境产生污染，目前的工业空气净化装置主要分喷淋式和吸附式两种。With the gradual improvement of the degree of industrialization in our country, the waste materials discharged by factories in daily production are increasing day by day, so the pollution to the surrounding environment is becoming more and more serious. Among the emissions from factories, exhaust gas is one of the main sources of pollution, especially in enterprises such as cement factories, foundries or feed factories, where the exhaust gas contains a large amount of particles, dust or heavy metal debris. In order to reduce the impact of factory waste gas on the environment, existing industrial plants are generally equipped with air purification devices, the purpose of which is to reduce the content of harmful substances in the air, so that the air discharged from the plant will not pollute the surrounding environment. The current industrial Air purification devices are mainly divided into spray type and adsorption type.
其中，中国专利ZL201420527312.3公开了一种多层喷淋的空气净化装置，该装置利用交错排列的隔离板构成蛇形风道，并在隔离板上设置喷淋头，使空气在通过风道时受到喷淋头的多次水洗，实现减少空气中颗粒、粉尘含量的效果。然而，该装置仅是以喷淋的方式使空气中的颗粒、粉尘重量增大并沉淀，不能对气体进行彻底清洗。并且，该装置在喷淋时产生的水流冲力会减慢风道中空气的流动速度，使风道内的空气带有水汽而变重，不利于空气的排出。Among them, Chinese patent ZL201420527312.3 discloses an air purification device with multi-layer spraying. The device uses staggered partition plates to form a serpentine air duct, and sprinklers are arranged on the partition plates to make the air pass through the air duct. It is washed by the sprinkler head for many times to achieve the effect of reducing the content of particles and dust in the air. However, this device only increases and precipitates the particles and dust in the air in the form of spraying, and cannot thoroughly clean the gas. Moreover, the force of the water flow generated by the device during spraying will slow down the flow velocity of the air in the air duct, making the air in the air duct heavy with water vapor, which is not conducive to the discharge of air.
另外，中国专利ZL201320094064.3公开了一种利用光触媒网和活性炭网相结合的空气净化器，通过活性炭的吸附作用及光触媒的降解作用，减少空气中有害气体分子的含量。但是，该净化器存在两个较大的缺陷。其一，由于颗粒较大、碎屑较多的废气会阻塞活性炭网及光触媒网的网眼，在如水泥厂、铸造厂或饲料厂等场合，使用者需要频繁对滤网进行清理，其使用十分不便；其二，该净化器内具有电器元件，当废气的湿度过大时候，会使电器元件出现短路而损坏，严重影响其使用寿命。因此，该净化器在工业上的应用具有很大的局限性。In addition, Chinese patent ZL201320094064.3 discloses an air purifier that uses a combination of photocatalyst net and activated carbon net to reduce the content of harmful gas molecules in the air through the adsorption of activated carbon and the degradation of photocatalyst. However, this purifier suffers from two major flaws. First, because the exhaust gas with larger particles and more debris will block the mesh of the activated carbon net and the photocatalyst net, in places such as cement plants, foundries or feed factories, users need to clean the filter screen frequently, which is very difficult to use. Inconvenience; its two, have electric element in this purifier, when the humidity of waste gas is too large, can make electric element appear short-circuit and damage, have a strong impact on its service life. Therefore, the industrial application of the purifier has great limitations.

本发明对现有技术的工业废气净化器进行改进，其优点如下：The present invention improves the industrial waste gas purifier of the prior art, and its advantages are as follows:
1、本发明的工业用废气清洗器结构中，箱体内设置利用粗滤液泵、粗滤网、粗滤回液管及吸附液泵、吸附网、吸附回液管构成的双循环过滤体系。通过相互独立的循环过滤，使粗滤网和吸附网可以分别对粒径较大的颗粒、粉尘和废气中有害微小粒子进行单独过滤，大大提高了粗滤网和吸附网的过滤效率。由于粗滤和吸附两个过程之间相互独立，在实际工作时粗滤和吸附可严格按照顺序进行，因而粗滤和吸附两种过滤方式在工作时不会产生干扰现象，极大加强了清洗器对废气的清洗效果。1. In the structure of the industrial exhaust gas cleaner of the present invention, a dual-circulation filtration system consisting of a crude filtrate pump, a coarse filter screen, a coarse filter liquid return pipe, an adsorption liquid pump, an adsorption network, and an adsorption liquid return pipe is arranged in the box. Through independent circulating filtration, the coarse filter and the adsorption net can separately filter the larger particles, dust and harmful tiny particles in the exhaust gas, which greatly improves the filtration efficiency of the coarse filter and the adsorption net. Since the two processes of coarse filtration and adsorption are independent of each other, the coarse filtration and adsorption can be carried out strictly in sequence during actual work, so the two filtration methods of coarse filtration and adsorption will not cause interference during work, which greatly enhances cleaning The cleaning effect of the device on the exhaust gas.
2、本发明的工业用废气清洗器结构中，储液槽上设置有隔层，吸附液槽通过隔层的阻隔相对于箱体构成密闭腔体。由于隔层使吸附液槽形成相对于箱体的密闭空间，在箱体内因粗滤产生的颗粒沉淀物不会进入吸附液槽内。在清洗液从吸附液槽内抽取至吸附网上时，避免粒径较大的颗粒、粉尘堵塞吸附网的网眼，改善了吸附网使用的稳定性。另外，粗滤液槽与粗滤液泵连通处设置过滤网，由于粗滤网用于过滤大粒径的粉尘和颗粒，在粗滤液泵处设置过滤网，可有效防止空气清洗时沉淀的粉尘和颗粒随着粗滤泵的抽取与清洗液一起流至粗滤网的背面，堵塞粗滤网的网眼。2. In the structure of the industrial waste gas cleaner of the present invention, a partition is arranged on the liquid storage tank, and the adsorption liquid tank forms a closed cavity relative to the box through the barrier of the partition. Because the interlayer makes the adsorption liquid tank form a closed space relative to the box body, the particle sediment produced by coarse filtration in the box body will not enter into the adsorption liquid tank. When the cleaning liquid is extracted from the adsorption liquid tank to the adsorption net, particles and dust with larger particle diameters are prevented from clogging the mesh of the adsorption net, and the stability of the adsorption net is improved. In addition, a filter screen is set at the connection between the crude filtrate tank and the crude filtrate pump. Since the coarse filter screen is used to filter large-sized dust and particles, a filter screen is installed at the crude filtrate pump, which can effectively prevent dust and particles deposited during air cleaning. With the suction of the coarse filter pump, the cleaning liquid flows to the back of the coarse filter, blocking the mesh of the coarse filter.
3、本发明的工业用废气清洗器结构中，吸附液槽中盛装有可发泡清洗液，可发泡清洗液的表面张力较大，其可粘附在吸附网的网眼上。当废气通过网眼时，清洗液在表面张力的作用下形成气泡，液膜对废气中的有害气体微粒进行吸附。当气泡内压力过大时，气泡即破裂，液膜形成液滴落至吸附网上，并再次粘附至网眼上。通过成膜-破泡-成膜的循环过程，使已经粗滤掉粉尘和颗粒的废气得到充分清洗。3. In the structure of the industrial waste gas cleaner of the present invention, the adsorption liquid tank is filled with a foamable cleaning liquid. The foamable cleaning liquid has a relatively high surface tension and can adhere to the meshes of the adsorption net. When the exhaust gas passes through the mesh, the cleaning liquid forms bubbles under the action of surface tension, and the liquid film adsorbs the harmful gas particles in the exhaust gas. When the pressure inside the bubble is too high, the bubble will burst, and the liquid film formed droplet will fall to the adsorption net and adhere to the mesh again. Through the cycle process of film formation-foam breaking-film formation, the exhaust gas that has been coarsely filtered out of dust and particles can be fully cleaned.
4、本发明的工业用废气清洗器结构中，吸附网与吸附液泵出水端连通的端部及粗滤网与粗滤液泵连通的端部均设有导液槽，吸附网与吸附回液管连通处设有集液槽，且吸附网为锥状网体、粗滤网为倒锥状网体。通过导液槽及集液槽的设置，使粗滤网和吸附网上的清洗液存在缓冲区，有效保障清洗液在粗滤网和吸附网上的均匀分布，提高清洗和吸附的稳定性。4. In the structure of the industrial exhaust gas cleaner of the present invention, the end of the adsorption net connected to the water outlet of the adsorption liquid pump and the end connected to the coarse filter net and the coarse filtrate pump are all provided with a liquid guide groove, and the adsorption net and the adsorption return liquid A liquid collection tank is provided at the connecting part of the pipe, and the adsorption net is a cone-shaped net body, and the coarse filter net is an inverted cone-shaped net body. Through the setting of the liquid guide tank and the liquid collection tank, the cleaning liquid on the coarse filter screen and the adsorption network has a buffer zone, which effectively ensures the uniform distribution of the cleaning liquid on the coarse filter screen and the adsorption network, and improves the stability of cleaning and adsorption.
5、本发明的工业用废气清洗器结构中，出气管内壁与箱体连通处设有吸湿层。吸湿层可对清洗完成的空气进行吸湿处理，有效防止湿气带至出气管的抽风装置上，避免损坏抽风装置的电器元件。5. In the structure of the industrial exhaust gas cleaner of the present invention, a hygroscopic layer is provided at the connection between the inner wall of the outlet pipe and the box body. The hygroscopic layer can perform hygroscopic treatment on the cleaned air, effectively preventing moisture from being brought to the exhaust device of the air outlet pipe, and avoiding damage to the electrical components of the exhaust device.

另外，储液槽上设有隔层43，隔层43把储液槽分为粗滤液槽41和吸附液槽42。粗滤液槽41与粗滤回液管61连通，吸附液槽42与吸附回液管71连通。所述隔层43呈弯折结构，其一边与箱体3的侧壁接触，另一边与箱体3的箱底接触，吸附液槽42通过隔层43的阻隔相对于箱体3构成密闭腔体。吸附液槽42通过隔层43的阻隔相对于箱体3构成密闭腔体。形成密闭腔体的吸附液槽42可有效避免经粗滤网6清洗后的粒径较大的颗粒、粉尘落至吸附液槽42内。粗滤液槽41的下部设有粗滤液排污口44，吸附液槽42的下部设有吸附液排污口45。上述排污口的作用是便于使用者在废气清洗器长时间使用后可分别对粗滤液槽41和吸附液槽42进行单独清洗，并更换清洗液。由于粗滤网6过滤的粒径较大的颗粒、粉尘会落至粗滤液槽41内，为避免颗粒和粉尘随着粗滤液泵51的作用被抽取至粗滤网6的背面，堵塞粗滤网6的网眼，在粗滤液槽41内与粗滤液泵51连通处设有一个过滤网46。隔层43上与吸附回液管71连通处设有密封件47，保障了吸附液槽42的密封性能。而为了实现吸附网7可对粗滤后的废气进行吸附处理，吸附液槽42内盛装有可发泡清洗液，利用液膜吸附的原理，以废气通过吸附网7时不断产生的成膜-破泡-成膜循环对废气进行充分清洗。本发明中，吸附网7可利用两层或以上的细孔网叠合而成，细孔网之间的间隙可加快吸附网7上成膜泡沫的破裂速度，提高了吸附网7的吸附效率。In addition, an interlayer 43 is provided on the liquid storage tank, and the interlayer 43 divides the liquid storage tank into a crude filtrate tank 41 and an adsorption liquid tank 42 . The crude filtrate tank 41 communicates with the crude filtration liquid return pipe 61 , and the adsorption liquid tank 42 communicates with the adsorption liquid return pipe 71 . The interlayer 43 has a bent structure, one side of which is in contact with the side wall of the box body 3, and the other side is in contact with the bottom of the box body 3, and the adsorption liquid tank 42 forms a closed cavity relative to the box body 3 through the barrier of the interlayer 43 . The adsorption liquid tank 42 forms a closed cavity relative to the box body 3 through the barrier of the interlayer 43 . The adsorption liquid tank 42 forming a closed cavity can effectively prevent particles and dust with larger particle diameters after being cleaned by the coarse filter 6 from falling into the adsorption liquid tank 42 . The lower part of the crude filtrate tank 41 is provided with a crude filtrate sewage outlet 44 , and the lower part of the adsorption liquid tank 42 is provided with an adsorption liquid sewage outlet 45 . The function of the above-mentioned sewage outlet is to facilitate the user to clean the crude filtrate tank 41 and the adsorption liquid tank 42 separately and replace the cleaning solution after the exhaust gas cleaner has been used for a long time. Because the larger particles and dust filtered by the coarse filter screen 6 will fall into the coarse filtrate tank 41, in order to prevent the particles and dust from being drawn to the back of the coarse filter screen 6 with the action of the coarse filtrate pump 51, the coarse filter will be blocked. The mesh of the net 6 is provided with a filter screen 46 at the place where the crude filtrate tank 41 communicates with the crude filtrate pump 51 . A seal 47 is provided on the interlayer 43 where it communicates with the adsorption liquid return pipe 71 to ensure the sealing performance of the adsorption liquid tank 42 . In order to realize that the adsorption net 7 can adsorb the coarsely filtered exhaust gas, the adsorption liquid tank 42 is filled with a foamable cleaning solution, and the film-forming process continuously produced when the exhaust gas passes through the adsorption net 7 is utilized by using the principle of liquid film adsorption. The bubble breaking-film forming cycle fully cleans the exhaust gas. In the present invention, the adsorption net 7 can be formed by laminating two or more layers of fine meshes, and the gap between the fine meshes can accelerate the bursting speed of the film-forming foam on the adsorption net 7, thereby improving the adsorption efficiency of the adsorption net 7. .
此外，进气管1设置在箱体3的下部，由于进气管1的上方为带液体的粗滤网6及吸附网7，为防止粗滤网6及吸附网7的液体积聚在进气管1内，进气管1自外向内往下倾斜设置，进气管1与粗滤网6相对的一侧设有出气孔11，另一侧设有排液孔12，排液孔12可设置于进气管1向下倾斜的端部，并于储液槽的液面相对。出气孔11与粗滤网6相对，可加快废气与粗滤网6的接触速度，避免气流在箱体3内产生乱流的现象。出气管2设于箱体3上部，出气管2内壁与箱体3连通处设有吸湿层21，且出气管2内设有抽风装置22。吸湿层21可对清洗后的气体进行吸湿处理，避免气体中的水汽带至抽风装置22上而损坏电器元件。抽风装置22的设置则是为了加快箱体3内气体的流速，利于清洗后的气体排出箱体3。In addition, the intake pipe 1 is arranged at the bottom of the box body 3. Since the top of the intake pipe 1 is a coarse filter screen 6 and an adsorption net 7 with liquid, in order to prevent the liquid of the coarse filter screen 6 and the adsorption net 7 from accumulating in the intake pipe 1 , the air intake pipe 1 is arranged inclined downward from the outside to the inside, the side of the air intake pipe 1 opposite to the coarse filter 6 is provided with an air outlet 11, and the other side is provided with a drain hole 12, and the drain hole 12 can be arranged on the air intake pipe 1 The end slopes downward and is opposite to the liquid level of the reservoir. The air outlet hole 11 is opposite to the coarse filter screen 6, which can speed up the contact speed between the exhaust gas and the coarse filter screen 6, and avoid the turbulent flow of the airflow in the box body 3. The air outlet pipe 2 is arranged on the upper part of the box body 3 , a hygroscopic layer 21 is provided at the communication part between the inner wall of the air outlet pipe 2 and the box body 3 , and an exhaust device 22 is arranged in the air outlet pipe 2 . The hygroscopic layer 21 can perform hygroscopic treatment on the cleaned gas, so as to prevent the water vapor in the gas from being brought to the exhaust device 22 and damage the electrical components. The setting of the exhaust device 22 is then in order to speed up the flow velocity of the gas in the box body 3 , which is beneficial to the gas discharged from the box body 3 after cleaning.
为了减少废气在过滤清洗后的流速损失，箱体3可以采用呈上小下大的锥状结构，提高废气在通过粗滤网6和吸附网7后的流速，具体如附图1所示。当然箱体3也可以采用非锥状结构，具体如图2所示。In order to reduce the flow rate loss of the exhaust gas after filtering and cleaning, the box 3 can adopt a conical structure with a small top and a large bottom to increase the flow rate of the exhaust gas after passing through the coarse filter 6 and the adsorption net 7, as shown in Figure 1. Of course, the box body 3 may also adopt a non-tapered structure, as shown in FIG. 2 .
本发明中，废气自上而下顺次通过粗滤网6和吸附网7，而吸附液槽42内的清洗液与粗滤液槽41的清洗液相互隔离。即使在正常使用时吸附网7上的清洗液滴落至粗滤网6上，并回流至粗滤液槽41内，因吸附液槽42的清洗液具有成膜的功能，同样可改善粗滤网6的过滤大型颗粒、粉尘的效果。因此清洗器使用时间越长，粗滤液槽41内可发泡的清洗液含量就越高，粗滤网6的过滤效果就越好。In the present invention, the exhaust gas passes through the coarse filter screen 6 and the adsorption screen 7 sequentially from top to bottom, and the cleaning liquid in the adsorption liquid tank 42 is isolated from the cleaning liquid in the crude filtrate tank 41 . Even if the cleaning liquid on the adsorption net 7 drops onto the coarse filter screen 6 during normal use, and returns to the coarse filtrate tank 41, because the cleaning liquid in the adsorption liquid tank 42 has a film-forming function, the coarse filter screen can also be improved. 6. The effect of filtering large particles and dust. Therefore, the longer the cleaning device is used, the higher the foamable cleaning solution content in the coarse filtrate tank 41 is, and the better the filtering effect of the coarse filter screen 6 is.
上述具体实施例仅为本发明效果较好的具体实施方式，凡与本发明的工业用废气清洗器相同或等同的结构，均在本发明的保护范围内。The above-mentioned specific embodiments are only specific implementations with better effects of the present invention, and all structures identical or equivalent to the industrial exhaust gas cleaner of the present invention are within the scope of protection of the present invention.
