Description

Technical Field

[0001] The present invention relates to the technical field of waste gas separation and filtration, and particularly relates to an organic waste gas separation and filtration device, a treatment system, a treatment method and an application. Background Art

[0002] Organic waste gas has problems such as strong odor and high nitrogen content, and cannot be directly discharged. It needs to be treated before discharge. The odor gases in the waste gas mainly include methane, hydrogen, hydrogen sulfide, ammonia, methanethiol, etc.

[0003] For the odor waste gas generated during garbage decomposition, distillation in a distillation tank, and waste gas generated during slag drying, in addition to problems such as strong odor and high nitrogen content, it also contains water vapor, oil stains and particulate matter, and the treatment of this type of waste gas is relatively difficult.

[0004] Currently, the treatment methods for the above-mentioned odor waste gas mainly include activated carbon adsorption method and pyrolysis incineration method. Among them, although the activated carbon adsorption method can achieve the purpose of deodorization, the water vapor, oil stains and particulate matter in the odor waste gas are likely to cause problems such as rapid decline in the adsorption capacity of activated carbon and poisoning and inactivation, resulting in the treatment equipment invested in the early stage basically becoming a decoration, and the activated carbon consumed during operation and the disposal cost are high. The pyrolysis incineration method is to promote the molecular decomposition and chemical bond breakage of organic substances in the pyrolysis furnace through a high-temperature environment for organic waste gas, so as to generate combustible gas, and completely burn in the incinerator. That is, the essence of the pyrolysis incineration method is based on the combustibility of odor gases. Among them, the reaction equation for methane combustion is: CH 4 + 2O 2 → CO 2 +2H 2 O. This reaction is an exothermic reaction, indicating that methane and oxygen react to form carbon dioxide and water; the reaction equation for hydrogen combustion is: 2H 2 + O 2 → 2H 2 O. This reaction is an exothermic reaction, indicating that hydrogen and oxygen react to form water; the chemical equation for hydrogen sulfide combustion is: 2H 2 S + 3O 2 → 2S + 2H 2 O. This reaction is an exothermic reaction, indicating that hydrogen sulfide and oxygen react to form sulfur and water; the chemical equation for ammonia combustion‌: 4NH 3 + 3O 2 → 6H 2 O + 2N 2 . This reaction is an exothermic reaction, indicating that ammonia and oxygen react to form nitrogen and water; the chemical equation for methanethiol combustion: CH 4 S (methanethiol) +3O 2 =SO 2+CO 2 +4H 2 O. This reaction is an exothermic reaction, indicating that methanethiol reacts with oxygen to produce sulfur dioxide, carbon dioxide and water. For organic waste gas containing water vapor, oil and particulate matter, if directly fed into pyrolysis incineration, it will not only affect the combustion efficiency, but also affect the service life of the incinerator.

[0005] Therefore, it is necessary to separate and filter the organic waste gas containing water vapor, oil and particulate matter to remove the water vapor, oil and particulate matter in the organic waste gas. Summary of the Invention

[0006] The purpose of the present invention is to provide an organic waste gas separation and filtration device to remove water vapor, oil and particulate matter in the organic waste gas.

[0007] In addition, the present invention also provides an organic waste gas separation and filtration device and a treatment system thereof, as well as a treatment method and application.

[0008] The present invention is realized through the following technical solutions: An organic waste gas separation and filtration device, comprising: A housing, with an air outlet pipe provided at the top thereof; A cooling air intake mechanism for introducing cooling waste gas into the housing; it includes an intake pipe penetrating through the housing, and a cooling component is arranged in the intake pipe; An oil absorption component is arranged at the outlet end of the intake pipe for adsorbing oil in the cooling waste gas. It includes a housing, and at least two oil absorption members are relatively arranged in the housing. A plurality of relatively arranged oil absorption members are alternately arranged from top to bottom. The oil absorption members are inclined, and the high end of the oil absorption member is connected to the inner wall of the housing through a telescopic member. When the oil absorption member is impacted by the cooling waste gas, the telescopic member reciprocates in the vertical direction; A spraying component is arranged above the oil absorption component for spraying the cooling waste gas treated by the oil absorption component; A moisture absorption component is arranged above the spraying component for treating the waste gas after spraying treatment to remove water vapor in the waste gas.

[0009] The present invention adds a cooling air intake mechanism, an oil absorption component, and a moisture absorption component on the basis of an existing spray tank. Among them, the function of the cooling air intake mechanism is to cool and lower the temperature of organic waste gas, so that the oil stain in the organic waste gas cools down to form oil droplets, and the oil droplets are easier to be adsorbed than the dispersed oil stains; the oil absorption component uses its oil absorption parts to adsorb the oil droplets in the organic waste gas to remove the oil stains in the organic waste gas. The present invention adopts a plurality of oil absorption parts arranged alternately from top to bottom, which can ensure that the organic waste gas led out by the cooling air intake mechanism can impact on the oil absorption parts. Moreover, the oil absorption parts of the present invention are inclined. When the oil absorption parts adsorb more oil droplets, the oil droplets can move downward along the oil absorption parts, reducing the adhesion amount of the oil droplets on the oil absorption parts and ensuring the oil droplet adsorption effect of the oil absorption parts. In addition, the high end of the oil absorption part of the present invention is connected to a telescopic part. When the oil absorption part is impacted by the cooling waste gas, the telescopic part reciprocates in the vertical direction to drive the oil absorption part to vibrate up and down, which is beneficial to make the oil droplets adsorbed on the oil absorption part move downward along the oil absorption part, further reducing the adhesion amount of the oil droplets on the oil absorption part; the spray component removes the particulate matter in the waste gas and further removes the oil stain through the spray liquid, that is, a small part of the oil stain that has not been adsorbed by the oil absorption component in time can be further removed by the spray component, and the moisture absorption component can remove the water vapor in the waste gas after spray treatment.

[0010] In summary, the organic waste gas separation and filtration device of the present invention can remove water vapor, oil stain, and particulate matter in the organic waste gas. Moreover, due to the adsorption of the oil stain by the front-end oil absorption component and the spraying of the particulate matter by the spray component, the blockage risk of the moisture absorption component can be greatly reduced.

[0011] In addition, the present invention integrates the cooling air intake mechanism, the oil absorption component, the spray component, and the moisture absorption component in the same housing, which has the advantages of high integration degree and small floor area.

[0012] In a preferred mode, an annular space interlayer is formed inside the side wall of the intake pipe, and a cooling water outlet pipe and a spray liquid pipe are installed in the annular space interlayer; the spray liquid pipe is used to supply spray liquid to the spray component; the cooling water outlet pipe, the cooling component, and an external water supply end form a circulation loop; both the spray component and the moisture absorption component are fixed on the outer wall of the intake pipe.

[0013] By forming an annular space interlayer inside the side wall of the intake pipe, the present invention can integrate the cooling water outlet pipe for cooling and the spray liquid pipe for spraying, so as to avoid the problem of affecting the sealing performance by setting multiple inlets on the housing.

[0014] In a preferred mode, the spray component includes a second annular main pipe, the second annular main pipe is coaxially arranged outside the intake pipe, a plurality of second branch pipes are arranged on the second annular main pipe, and a plurality of nozzles are arranged on the second branch pipes; the second annular main pipe is connected to the spray liquid pipe through a second joint.

[0015] The spray component structure set as above in the present invention is to arrange the second annular main pipe at the central position and on the outer wall of the intake pipe. This can not only cover the waste gas that moves upward after being adsorbed and treated by the oil absorption component to ensure that all waste gas passes through the spray, but also the second annular main pipe arranged at the central position can cooperate with the spray liquid pipe in the annular space layer.

[0016] In a preferred embodiment, the moisture absorption component includes a fixing frame arranged on the outer wall of the intake pipe, and the fixing frame is filled with water-absorbing filler.

[0017] The above setting of the present invention can ensure that the waste gas moving upward after spraying can all enter the moisture absorption component for moisture removal treatment.

[0018] In a preferred embodiment, the cooling component includes a number of relatively arranged cooling plates. A number of relatively arranged cooling plates are alternately arranged from top to bottom, and there is a gap between two adjacent upper and lower cooling plates; the cooling plate is a hollow plate, and two adjacent upper and lower cooling plates are connected by a connecting pipe, that is, a number of hollow plates are connected in series through the connecting pipe to ensure that each hollow plate is on the same circulation loop.

[0019] The cooling component set as above in the present invention can not only cool down the organic waste gas entering the intake pipe, but also, due to the certain blocking effect of the cooling plate on the organic waste gas, can extend the time of the organic waste gas in the intake pipe to ensure the cooling effect of the organic waste gas.

[0020] In a preferred embodiment, the cooling plate is arranged horizontally or obliquely.

[0021] In a preferred embodiment, the top of the housing is connected to the outlet end of the intake pipe, and the housing is arranged outside the intake pipe. The oil absorption member is arranged below the outlet end of the intake pipe. The bottom of the housing is an open end, and there are a plurality of air guiding through grooves on the side wall of the housing above the oil absorption member.

[0022] The above setting of the present invention can prevent the spray liquid from entering the housing and affecting the adsorption effect of the oil absorption member. And compared with the open structure of the top of the housing, it can not only increase the time of the organic waste gas in the housing, but also ensure that there is a relatively large pressure in the housing to realize the reciprocating movement of the telescopic member up and down, which is beneficial to shake off the oil droplets on the oil absorption member.

[0023] In a preferred embodiment, the oil absorption member includes a first oil absorption plate, and the surface of the first oil absorption plate is a rough surface, or the surface of the first oil absorption plate has a number of protrusions.

[0024] The present invention can utilize the rough surface and several protrusions to increase the adsorption force of oil droplets on the first oil absorption plate, improve the adsorption effect of the first oil absorption plate on oil droplets in the waste gas. When the cooled waste gas moves downward and impacts on the first oil absorption plate, since the oil and grease in the cooled waste gas form oil droplets with relatively large adhesion force, and when they impact on the first oil absorption plate with a rough surface or several protrusions under a certain pressure, the oil droplets can be adsorbed by the first oil absorption plate.

[0025] In a preferred embodiment, the oil absorption member includes a first oil absorption plate and a second oil absorption plate arranged in parallel; the high end of the first oil absorption plate is connected to the telescopic member, and the high end of the second oil absorption plate is fixedly connected to the inner wall of the housing; both the first oil absorption plate and the second oil absorption plate are of a hollow structure, and several sponge columns are arranged between the first oil absorption plate and the second oil absorption plate.

[0026] The first oil absorption plate, the sponge columns and the second oil absorption plate of the present invention form a three - stage oil and grease adsorption, which can improve the adsorption effect. And since the first oil absorption plate can move up and down while the second oil absorption plate is fixed, when the first oil absorption plate moves downward, it can squeeze the sponge columns, and squeeze out the oil droplets adsorbed in the sponge columns, so that the sponge columns can recover the adsorption effect on oil droplets, thereby ensuring that the sponge columns always have a good adsorption effect on oil and grease.

[0027] In a preferred embodiment, several positioning cylinders are arranged on the upper end surface of the second oil absorption plate, one end of the sponge column is embedded in the positioning cylinder, and the other end is in contact with the lower end surface of the first oil absorption plate.

[0028] In a preferred embodiment, it further includes: A drying assembly, which is arranged between the spraying assembly and the moisture absorption assembly, is connected to the external dry air flow supply end, and is used for drying the moisture absorption assembly.

[0029] When the moisture absorption assembly reaches saturation or its ability to absorb water vapor is poor, dry hot air can be passed into the moisture absorption assembly through the drying assembly to dry the moisture absorption assembly, so that the moisture absorption assembly can recover the ability to absorb water vapor.

[0030] In a preferred embodiment, the drying assembly includes a first annular main pipe, which is coaxially arranged on the outer wall of the intake pipe. The first annular main pipe is connected with a plurality of first branch pipes, and a plurality of air outlet cylinders are arranged on the first branch pipes. The outlet of the air outlet cylinder is arranged upward, and a one - way air - permeable membrane is arranged in the air outlet cylinder.

[0031] The one - way air - permeable membrane of the present invention only allows the gas in the air outlet cylinder to flow out, but does not allow the outside gas to enter the air outlet cylinder, that is, the drying assembly of the present invention will not affect the filtration and separation treatment of the organic waste gas.

[0032] In a preferred embodiment, an annular space is formed within the sidewall of the intake pipe, and a drying air flow pipe is disposed within the annular space. One end of the drying air flow pipe is connected to the drying assembly, and the other end is connected to an external drying air flow supply end.

[0033] In a preferred embodiment, the outlet end of the intake pipe is of a reduced diameter structure or is provided with a pressurizing unit.

[0034] The above arrangements of the present invention are all for increasing the air flow pressure at the outlet end of the intake pipe, providing an impact force during the impact between the cooling exhaust gas and the moisture-absorbing member, and facilitating improving the adsorption effect of the moisture-absorbing member on the oil droplets in the cooling exhaust gas.

[0035] An organic waste gas treatment system includes: An organic waste gas separation and filtration device; An incinerator, connected to the outlet pipe of the organic waste gas separation and filtration device through an exhaust main pipe; It further includes a spray tank and an activated carbon adsorption tank sequentially arranged at the rear end of the incinerator.

[0036] In a preferred embodiment, the organic waste gas treatment system further includes: A preheating chamber; an intake air passage and an exhaust air passage are formed therein through a partition; Both ends of the intake air passage are respectively connected to the exhaust main pipe and the inlet end of the incinerator; One end of the exhaust air passage is connected to the outlet end of the incinerator through a bypass pipe, and the other end is connected to the spray tank through a pipe, and a blower is provided on this pipe.

[0037] In a preferred embodiment, an exhaust branch pipe is provided on the exhaust main pipe, and this exhaust branch pipe can be used for discharging moisture during the drying of the moisture-absorbing component.

[0038] By providing the preheating chamber in the present invention, when the gas burned by the incinerator enters the exhaust air passage, it can preheat the organic waste gas in the intake air passage, and can improve the incineration efficiency of the incinerator.

[0039] A treatment method for an organic waste gas treatment system includes the following steps: S1. The odor waste gas generated during the decomposition of garbage and the distillation in the distillation tank, and the waste gas generated during the drying of the slag are filtered and separated through the organic waste gas separation and filtration device to remove water vapor, oil stains, and particulate matter in the waste gas; S2. The filtered waste gas enters the incinerator for incineration treatment to burn the organic gas; S3. The gas after combustion is sequentially subjected to spray filtration and activated carbon adsorption filtration and then discharged.

[0040] Specifically, step S1 includes the following steps: S11. The odor exhaust gas generated during garbage decomposition and distillation in the distillation tank, and the exhaust gas generated during the drying of the slag are respectively introduced into the intake pipe through three exhaust gas inlets. The exhaust gas is cooled and temperature-reduced by the cooling component to obtain cooled exhaust gas, and the oil stain in the exhaust gas forms oil droplets after cooling. S12. The cooled exhaust gas enters the oil absorption component, and the oil absorption part adsorbs the oil droplets. S13. The exhaust gas after adsorbing the oil droplets enters the housing, and is subjected to spray treatment by the spray component to further remove the oil stain and particulate matter. S14. The gas after spray treatment enters the moisture absorption component to remove water vapor.

[0041] The application of the above-mentioned organic waste gas separation and filtration device or the above-mentioned organic waste gas treatment system in the treatment of organic waste gas containing oil stains.

[0042] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. By adding a cooling air intake mechanism, an oil absorption component and a moisture absorption component in the existing spray tank, the cooling air intake mechanism is used to cool and temperature-reduce the organic waste gas, so that the oil stain in the organic waste gas cools down to form oil droplets. The oil droplets are easier to be adsorbed compared with the dispersed oil stains. The oil absorption component, the spray component and the moisture absorption component form a three-stage filtration, which are respectively used to remove the oil stain, particulate matter and water vapor in the organic waste gas, realizing the removal of water vapor, oil stain and particulate matter in the organic waste gas by the organic waste gas separation and filtration device. And because the oil stain is adsorbed and removed by the front-end oil absorption component and the particulate matter is removed by spraying of the spray component, the risk of blockage of the moisture absorption component can be greatly reduced.

[0043] 2. By arranging a drying component between the spray component and the moisture absorption component, the moisture absorption component can be dried, so that the moisture absorption component can restore its ability to absorb water vapor, that is, the desorption of the moisture absorption component can be completed without disassembling the moisture absorption component, ensuring the adsorption ability of the moisture absorption component and being convenient to operate.

[0044] 3. First, the organic waste gas separation and filtration device is used to filter and separate the organic waste gas to remove the oil stain, particulate matter and water vapor in the organic waste gas, and then the incinerator is used for incineration treatment, which can not only realize the degradation treatment of the organic waste gas, but also avoid affecting the incineration efficiency and service life of the incinerator.

Detailed implementation manners

[0047] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with embodiments. The illustrative implementation manners and descriptions of the present invention are only used to explain the present invention and do not limit the present invention. The following described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0048] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present invention. However, it is obvious to those of ordinary skill in the art that the present invention does not have to employ these specific details.

The technical means used in the embodiments, unless otherwise specified, are all conventional means well-known to those skilled in the art.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0050] Embodiment 1: The odor-containing waste gas generated during garbage decomposition and distillation tank distillation and the waste gas generated during residue drying are waste gases generated by the same factory. Separately treating them requires a large number of equipment and high costs. Therefore, it is considered to use the same set of equipment to treat the odor-containing waste gas generated during garbage decomposition and distillation tank distillation and the waste gas generated during residue drying. Since the above-mentioned organic waste gas contains organic gases that can produce odors, as well as water vapor, oil stains, and particulate impurities, if it is directly incinerated using the incinerator 300, the incineration efficiency will be affected and the service life of the incinerator 300 will be greatly reduced. If activated carbon is used for adsorption and filtration, it will cause the activated carbon to be poisoned.

[0051] To solve the above problems, this embodiment provides an organic waste gas separation and filtration device to achieve separation and filtration treatment of the above-mentioned organic waste gas, remove water vapor, oil stains, and particulate impurities in the organic waste gas, and avoid the impact on subsequent incineration, as Figures 1-4 、 Figures 6-8 shown, which includes: A housing 1, which forms a sealed environment inside. An air outlet pipe 11 is provided at the top of the housing 1, and the air outlet pipe 11 is used to export the organic waste gas after separation and filtration treatment out of the housing 1; a drain pipe 12 is provided at the bottom of the housing 1, and the drain pipe 12 is provided with a drain valve for discharging the waste liquid generated by spraying out of the housing 1.

[0052] A cooling air intake mechanism 2, which is used to introduce cooling waste gas into the housing 1; it includes an intake pipe 21 passing through the housing 1. The top of the intake pipe 21 is located outside the housing 1, the bottom of the intake pipe 21 is located inside the housing 1 and has a spacing from the bottom of the housing 1, and a cooling component is provided inside the intake pipe 21; the cooling component can be any existing structure capable of cooling the gas. For example, as Figure 2As shown in the figure, in this embodiment, the cooling assembly includes a spiral tube 30 disposed on the inner wall of the intake pipe 21. An inlet 24 and an outlet 23 communicating with the spiral tube 30 are provided on the side wall of the intake pipe 21. A second valve 241 and a first valve 231 are respectively provided on the inlet 24 and the outlet 23. The spiral tube 30 forms a circulation loop with an external cooling device through the inlet 24 and the outlet 23. Specifically, both ports of the spiral tube 30 in this embodiment are disposed outside the housing 1, that is, the spiral tube 30 in this embodiment is a vertical spiral, that is, a pipe extends from top to bottom to the bottom and then bends and extends upward to the top and then extends downward to the bottom and then bends, repeating like this, and the inlet 24 and the outlet 23 are both disposed outside the housing 1; or the spiral tube 30 is composed of several vertical cooling tubes 301, as Figure 3 shown, several vertical cooling tubes 301 are arranged circumferentially, and adjacent two vertical cooling tubes 301 are connected by a connecting cooling tube 302. The adjacent two connecting cooling tubes 302 in the circumferential direction are arranged vertically. For example, for the adjacent vertical cooling tubes 301 numbered 1#, 2#, and 3#, the upper ends of 1# and 2# are connected by a connecting cooling tube 302, and the lower ends of 2# and 3# are connected by a connecting cooling tube 302, and so on.

[0053] An oil absorption assembly 6 is disposed at the outlet end of the intake pipe 21 and is used for adsorbing oil stains in the cooling waste gas. It includes a housing 61. At least two oil absorption members are relatively disposed in the housing 61. A plurality of relatively disposed oil absorption members are alternately arranged from top to bottom, and there is a vertical distance between adjacent two oil absorption members up and down. The end portions of adjacent two oil absorption members away from the housing 61 have an overlapping portion in the horizontal direction to ensure that the organic waste gas entering the housing 61 can contact the oil absorption members and prevent the organic waste gas not adsorbed by the oil absorption members from overflowing the housing 61. Preferably, the oil absorption member is inclined, and the high end of the oil absorption member is connected to the inner wall of the housing 61 through a telescopic member 63. When the oil absorption member is impacted by the cooling waste gas, the telescopic member 63 reciprocates in the vertical direction; specifically, the telescopic member 63 includes two fixed cylinders 631 fixed on the inner wall of the housing 61. The two fixed cylinders 631 are relatively disposed, and the opposite ends are open ends and the other ends are closed ends. The telescopic member 63 further includes a connecting rod 632 and a spring 633. Springs 633 are respectively disposed at both ends of the connecting rod 632, and the springs 633 at both ends are respectively embedded in the two fixed cylinders 631. The high end of the oil absorption member is connected to the connecting rod 632. The elastic force of the spring 633 is used to realize the vertical reciprocating movement of the connecting rod 632, and further drive the vertical reciprocating movement of the oil absorption member.

[0054] In this embodiment, by arranging the oil absorption member inclined and connecting its high end with the telescopic member, it is beneficial to make the oil droplets adsorbed on the oil absorption member slide off, reduce the oil droplet content on the oil absorption member, and ensure the adsorption capacity of the oil absorption member.

[0055] In a specific case, the housing 61 has a square structure. The top of the housing 61 is connected to the outlet end of the intake pipe 21, and the housing 61 is arranged outside the intake pipe 21. The oil suction member is arranged below the outlet end of the intake pipe 21. And its bottom is an open end. An oil suction member is arranged on each of the two symmetric side walls of the housing 61. Among them, the lower end of the oil suction member on the right side is located above the lower end of the oil suction member on the left side, and there is a vertical distance between the two for realizing the sliding of oil droplets.

[0056] Preferably, the top of the housing 61 is connected to the connecting cylinder 62, and the connecting cylinder 62 is connected to the intake pipe 21, so that the oil suction assembly 6 is arranged at the outlet end of the intake pipe 21. And a plurality of air guiding grooves 68 are arranged above the oil suction member on the side wall of the housing 61. The organic waste gas that has adsorbed oil droplets through the oil suction member is led out of the housing 61 through the air guiding grooves 68 and enters the outer shell 1. The above setting can prevent the spraying liquid from entering the housing 61 and affecting the adsorption effect of the oil suction member. And compared with the open structure at the top of the housing 61, it can not only increase the residence time of the organic waste gas in the housing 61, but also ensure that there is a relatively large pressure in the housing 61 to realize the reciprocating up and down movement of the telescopic member 63, which is beneficial to shake off the oil droplets on the oil suction member.

[0057] The oil suction member can be any structure that can realize the adsorption of oil droplets. In this embodiment, as Figures 6-8 shown, the oil suction member includes a first oil suction plate 64. The surface of the first oil suction plate 64 is a rough surface, or the surface of the first oil suction plate 64 has a number of protrusions. The first oil suction plate 64 is inclined, and the high end of the first oil suction plate 64 is connected to the connecting rod 632.

[0058] In a preferred case, the outlet end of the intake pipe 21 is a reduced diameter structure or is provided with a pressurizing unit to increase the gas pressure at the outlet end of the intake pipe 21, improve the pressure of the organic waste gas hitting the first oil suction plate 64, improve the vertical reciprocating movement effect of the first oil suction plate 64, facilitate shaking off the oil droplets on the first oil suction plate 64, and can also increase the pressure when the organic waste gas hits the first oil suction plate 64, which is beneficial to improving the adsorption effect of the first oil suction plate 64 on the oil droplets in the organic waste gas.

[0059] The spraying assembly 5 is arranged above the oil suction assembly 6 and is used for spraying the cooled waste gas processed by the oil suction assembly 6. The spraying assembly 5 can be any existing structure that realizes spraying. In this embodiment, as Figure 4As shown, the spraying assembly 5 includes a second annular main pipe 51, which is coaxially arranged outside the intake pipe 21. A plurality of second branch pipes 52 are provided on the second annular main pipe 51, and a number of spray nozzles 53 are provided on the second branch pipes 52; the second annular main pipe 51 is connected to the spraying liquid pipe 9 through a second joint 55. Specifically, a plurality of second fixing plates 54 are provided at the top or bottom of the second annular main pipe 51, and the second fixing plates 54 are fixed to the outer wall of the intake pipe 21 by bolts. In this embodiment, a number of spray nozzles 53 provided on the same second branch pipe 52 are arranged at equal intervals.

[0060] The moisture absorption assembly 3 is arranged above the spraying assembly 5 and is used for absorbing moisture from the organic waste gas that has undergone spraying treatment to remove water vapor. The moisture absorption assembly 3 includes water absorption fillers 32, such as calcium oxide, resin, etc. In this embodiment, in order to facilitate the fixation of the water absorption fillers 32, the moisture absorption assembly 3 includes a fixing frame 31 provided on the outer wall of the intake pipe 21, and the water absorption fillers 32 are filled in the fixing frame 31. The center of the fixing frame 31 has an annular fixing plate, and the annular fixing plate is fixed to the outer wall of the intake pipe 21 by bolts. A placement frame for placing the water absorption fillers 32 is provided on the outer wall of the annular fixing plate.

[0061] In a preferred case, an annular cavity sandwich 22 is formed inside the side wall of the intake pipe 21, and a cooling water outlet pipe 8 and a spraying liquid pipe 9 are installed in the annular cavity sandwich 22; the spraying liquid pipe 9 is used to supply spraying liquid to the spraying assembly 5; the cooling water outlet pipe 8, the cooling assembly and an external water supply end form a circulation loop; a liquid inlet 25 is provided on the outer wall of the intake pipe 21, a third valve 251 is provided on the liquid inlet 25, one end of the liquid inlet 25 is connected to an external liquid supply device, and the other end is connected to the second joint 55 through the spraying liquid pipe 9.

[0062] In this embodiment, a cooling air intake mechanism 2, an oil absorption assembly 6 and a moisture absorption assembly 3 are added to the existing spraying tank. Among them, the function of the cooling air intake mechanism 2 is to cool and lower the temperature of the organic waste gas, so that the oil stains in the organic waste gas are cooled to form oil droplets. The oil droplets are easier to be adsorbed compared with the dispersed oil stains. The oil absorption assembly 6, the spraying assembly 5 and the moisture absorption assembly 3 form a three-stage filtration, which are respectively used to remove oil stains, particulate matters and water vapor in the organic waste gas, realizing the removal of water vapor, oil stains and particulate matters in the organic waste gas by the organic waste gas separation and filtration device. And, since the oil stains are adsorbed and removed by the front-end oil absorption assembly 6 and the particulate matters are removed by spraying through the spraying assembly 5, the blockage risk of the moisture absorption assembly 3 can be greatly reduced.

[0063] Embodiment 2: This embodiment is based on Embodiment 1, and the difference from Embodiment 1 is that, as Figure 5 shown, a number of spray nozzles 53 provided on the same second branch pipe 52 are arranged at unequal intervals, and the distance between two adjacent spray nozzles 53 shows a gradually decreasing trend from the end connected to the second annular main pipe to the other end.

[0064] Example 3: This example is based on Example 1, and the difference from Example 1 is that as Figure 9 shown, the structure of the oil absorption member is different. In this example, in order to further improve the oil absorption effect of the oil absorption member, the oil absorption member includes a first oil absorption plate 64 and a second oil absorption plate 67 arranged in parallel; the high end of the first oil absorption plate 64 is connected to the telescopic member 63, and the high end of the second oil absorption plate 67 is fixedly connected to the inner wall of the housing 61 or fixedly connected to the fixed cylinder 631 to ensure that the second oil absorption plate 67 is fixed differently; both the first oil absorption plate 64 and the second oil absorption plate 67 are of a hollow structure, and a number of sponge columns 65 are arranged between the first oil absorption plate 64 and the second oil absorption plate 67. A three-stage adsorption is formed among the first oil absorption plate 64, the sponge columns 65, and the second oil absorption plate 67, and the sponge columns 65 have a good adsorption effect on oil droplets.

[0065] In this example, the specific fixing method of the sponge columns 65 is that a number of positioning cylinders 66 are arranged on the upper end surface of the second oil absorption plate 67. The positioning cylinders 66 are arranged in one-to-one correspondence with the sponge columns 65. One end of the sponge column 65 is embedded in the positioning cylinder 66, and the other end contacts the lower end surface of the first oil absorption plate 64. When the first oil absorption plate 64 is not subjected to a downward pressure, the top of the sponge column 65 contacts the lower end surface of the first oil absorption plate 64. When the first oil absorption plate 64 is subjected to a downward pressure, the first oil absorption plate 64 squeezes the sponge column 65 to squeeze out the oil droplets in the sponge column 65 to ensure the adsorption effect of the sponge column 65 on the oil droplets.

[0066] Example 4: This example is based on Example 1, and the difference from Example 1 is that as as Figure 10 、 Figure 11As shown, the structures of the cooling components are different. In this embodiment, in order to further improve the cooling effect of the cooling components, the cooling components include a plurality of cooling plates 27 arranged oppositely. The plurality of cooling plates 27 arranged oppositely are alternately arranged from top to bottom, and there is a vertical distance between two adjacent cooling plates 27 up and down, and the projections of the ends of two adjacent cooling plates 27 away from the inner wall of the intake pipe 21 in the horizontal direction have an overlapping part, so as to ensure that the organic waste gas entering the intake pipe 21 can contact the cooling plates 27. Not only is the cooling realized by using the cooling plates 27, but the cooling plates 27 also block the organic waste gas, which can increase the residence time of the organic waste gas in the intake pipe 21 and improve the cooling effect. Specifically, the cooling plate 27 is a hollow plate, and two adjacent cooling plates 27 up and down are connected by a connecting pipe 28. The cooling plate 27 is horizontally arranged or inclined, and preferably inclined. More specifically, the topmost cooling plate 27 is connected to the water inlet 24 provided on the side wall of the intake pipe 21, and the lowermost cooling plate 27 is connected to the water outlet 23 provided on the side wall of the intake pipe 21 through the cooling water outlet pipe 8.
