[0003] Existing organic waste gas collection devices have poor purification effects on waste gas and cannot effectively purify it. The treated gas is then discharged into the atmosphere and pollutes the air. Summary of the Invention

[0004] Based on the problems mentioned in the background technology above, this utility model provides a gas collection device for treating organic waste gas, which solves the problem that existing gas collection devices for treating organic waste gas have poor purification effect on waste gas, cannot effectively purify waste gas, and pollute the air after the treated gas is discharged into the atmosphere.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An organic waste gas collection device for treatment includes:

[0007] The main tank body has a main tank cover on its top, and an air inlet pipe is provided on the main tank cover;

[0008] The probe fork includes a sleeve, which is disposed at the bottom opening of the air intake pipe. Multiple branch pipes are arranged in an array on the sleeve, and multiple nozzles are provided on the straight rod portion of each branch pipe.

[0009] The auxiliary tank includes a lower auxiliary tank and an upper auxiliary tank. The upper part of the main tank is connected to the lower part of the lower auxiliary tank through a gas supply pipe. The top of the upper auxiliary tank is provided with an auxiliary tank cover, and an exhaust pipe is provided on the auxiliary tank cover.

[0010] A layered filter assembly is disposed within the auxiliary tank.

[0011] Based on the above technical solution, the present invention has made the following improvements:

[0012] Furthermore, the layered filtration assembly includes four functional filtration components, which include an activated alumina filter layer, a silica gel layer, a zeolite molecular sieve layer, and an activated carbon layer. The activated alumina filter layer, silica gel layer, zeolite molecular sieve layer, and activated carbon layer are arranged sequentially from bottom to top within the sub-tank body.

[0013] Furthermore, the activated alumina filter layer includes a container basket, which is installed in the lower auxiliary tank via a hanging platform. The bottom of the container basket is provided with multiple air supply pipes, and the container basket is filled with activated alumina.

[0014] Furthermore, the silicone layer includes a second container basket, which is mounted on the lower part of the upper auxiliary tank via a support platform.

[0017] Furthermore, a drain pipe is provided at the bottom of the main tank, and a control valve is provided on the drain pipe.

[0018] The beneficial effects of this utility model are:

[0019] 1. The main tank, main tank cover, air inlet pipe and probe fork are combined. The main tank can be filled with neutralizing liquid. The lower half of the probe fork is immersed in the neutralizing liquid. When the organic waste gas is sent in through the air inlet pipe, the organic waste gas enters the probe fork and is then sprayed into the neutralizing liquid through each nozzle. This promotes the organic waste gas to undergo a preliminary dissolution reaction with the neutralizing liquid in the main tank, so that the impurities in the organic waste gas are dissolved in the neutralizing liquid.

[0020] 2. Through the set auxiliary tank, gas supply pipe, auxiliary tank cover, exhaust pipe and layered filter assembly, after the organic waste gas is initially dissolved by the neutralizing liquid, the pre-treated organic waste gas can be sent into the auxiliary tank through the gas supply pipe. When the organic waste gas passes through the layered filter assembly in the auxiliary tank and is discharged along the exhaust pipe, the layered filter assembly can adsorb the pollutants in the pre-dissolved organic waste gas.

Detailed Implementation

[0026] As shown in Figures 1 and 2, a gas collection device for treating organic waste gas includes:

[0027] The main tank 101 has a main tank cover 104 on top and an air inlet pipe 105 on the main tank cover 104. The air inlet pipe 105 can supply organic waste gas into the main tank 101. The probing fork includes a sleeve 201, which is located at the bottom of the air inlet pipe 105. Multiple branch pipes 202 are arranged in an array on the sleeve 201. Multiple spray holes 203 are provided on the straight part of each branch pipe 202. The main tank 101 can hold neutralizing liquid, and the depth of the neutralizing liquid is located at the intersection of the inclined part and the straight part of the branch pipe 202.

[0028] When organic waste gas is introduced through the inlet pipe 105, it enters the casing 201, then the branch pipes 202, and finally is ejected from the nozzles 203 into the neutralizing liquid in the main tank 101. Subsequently, the organic waste gas permeates through the neutralizing liquid and gathers at the top of the main tank 101. During this process of ejecting the organic waste gas from the nozzles 203 into the neutralizing liquid in the main tank 101 and then permeating through it, the organic waste gas undergoes a preliminary dissolution reaction with the neutralizing liquid in the main tank 101, causing impurities in the organic waste gas to dissolve in the neutralizing liquid.

[0029] The bottom of the main tank 101 is provided with a drain pipe 102, and a control valve 103 is provided on the drain pipe 102. Opening the control valve 103 allows the drain pipe 102 to be open, so that the neutralized liquid in the main tank 101 can be discharged.

[0030] The auxiliary tank includes a lower auxiliary tank 301 and an upper auxiliary tank 302. The upper part of the main tank 101 is connected to the lower part of the lower auxiliary tank 301 through the gas supply pipe 4. The top of the upper auxiliary tank 302 is provided with an auxiliary tank cover 303, and an exhaust pipe 304 is provided on the auxiliary tank cover 303.

[0031] The layered filter assembly is located inside the sub-tank. The layered filter assembly includes four functional filter components: an activated alumina filter layer, a silica gel layer, a zeolite molecular sieve layer, and an activated carbon layer. The activated alumina filter layer, silica gel layer, zeolite molecular sieve layer, and activated carbon layer are arranged sequentially from bottom to top inside the sub-tank.

[0032] The activated alumina filter layer includes a container basket 501, which is installed in the lower auxiliary tank 301 via a hanging platform 305. Multiple air supply pipes 502 are installed at the bottom of the container basket 501. The container basket 501 is densely filled with activated alumina 503. The activated alumina 503 can dry the gas and adsorb chlorides and fluorides.

[0033] The silica gel layer includes a second container 601, which is set at the lower part of the upper auxiliary tank 302 via a support platform 306. Multiple gas supply pipes 602 are provided at the bottom of the second container 601. The second container 601 is filled with silica 603, which is silica 603 with a high specific area, used to adsorb polar molecules of acidic gases.

[0034] The zeolite molecular sieve layer includes a container basket 3 701, which is stacked on top of a container basket 2 601. The container basket 3 701 contains aluminosilicate 702, which is a synthetic porous aluminosilicate 702. The porous aluminosilicate 702 can adsorb small molecule gases such as NH3 and H2S.

[0035] The activated carbon layer includes a container basket 4 801, which is stacked on top of a container basket 3 701. The container basket 4 801 is filled with activated carbon 802, which can adsorb VOCs and sulfides.

[0036] After the organic waste gas undergoes preliminary dissolution reaction treatment by the neutralizing liquid, the pre-treated organic waste gas can be sent to the bottom area of ​​the lower auxiliary tank 301 of the auxiliary tank through the gas transmission pipe 4. Then, the organic waste gas enters the activated alumina 503 through the first gas transmission pipe 502 and passes through it. Subsequently, it passes through the second gas transmission pipe 602 and enters the silica 603, aluminosilicate 702 and activated carbon 802 in sequence. Finally, it collects at the auxiliary tank cover 303 and is discharged from the exhaust pipe 304. During the process of the organic waste gas passing through the activated alumina 503, silica 603, aluminosilicate 702 and activated carbon 802 in sequence, the pollutants in the organic waste gas can be captured by physical or chemical adsorption, so that the discharged gas meets the corresponding environmental protection requirements.
