An exhaust pipe 22 is fixedly connected to the top of the processing box 20 at the position of the fan assembly 21. The exhaust pipe 22 is a hollow circular tube and its bottom can communicate with the cavity of the processing box 20. The fan assembly 21 is a conventional suction fan and is driven by a motor. The motor is electrically connected to the corresponding power supply. The top opening of the air inlet pipe 23 is connected to the pipe for conveying exhaust gas. A valve is installed at the drain outlet 24. This is existing technology and will not be described in detail here.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air filtration structure is located at the bottom of the cavity of the treatment box 20 for filtering exhaust gas. The air filtration structure includes: a fixed plate 30, a through groove 31, and a guide plate 32. The fixed plate 30 is fixedly connected to the cavity of the treatment box 20. The through groove 31 is opened through the top of the fixed plate 30. The guide plate 32 is fixedly connected to the bottom wall of the fixed plate 30. There is a gap between the bottom of the guide plate 32 and the bottom of the cavity of the treatment box 20.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixed plate 30 and the guide plate 32 are rectangular plates. The guide plate 32 is obliquely placed at the bottom of the fixed plate 30. The lowest point of the bottom of the guide plate 32 can be aligned with the top of the air inlet slot on the wall of the processing box 20. The through slot 31 is located on one side of the highest point of the top of the guide plate 32. The through slot 31 is rectangular. The air filtration structure also includes a clustering plate 33, a filter frame 34, and an activated carbon plate 35. The clustering plate 33 is fixedly connected to the bottom of the guide plate 32. The filter frame 34 is fixedly connected to the cavity of the processing box 20. The activated carbon plate 35 is fixedly connected to the wall of the filter frame 34. The filter frame 34 is located above the fixed plate 30. The clustering plate 33 is rectangular. Multiple clustering plates 33 are evenly arranged at the bottom of the guide plate 32. Each clustering plate 33 is located at... The bottom of the guide plate 32 is vertical. The filter frame 34 is composed of a rectangular plate in the middle and two rectangular plates symmetrically placed downwards on both sides. A rectangular groove for the activated carbon plate 35 is opened through the center of the top of the filter frame 34. The activated carbon plate 35 is installed in the rectangular groove at the top of the filter frame 34. The wall of the treatment box 20 is also provided with a recycling structure, which includes an inlet trough 40, an overflow trough 42, an inclined plate 44 and a baffle 45. The inlet trough 40 is opened on the left side wall of the cavity of the treatment box 20. The overflow trough 42 is also opened on the wall of the treatment box 20 with the same water inlet trough 40. The inclined plate 44 is fixedly connected to the wall of the cavity of the treatment box 20 with the same overflow trough 42. The baffle 45 is fixedly connected to the bottom of the side wall of the fixed plate 30.

[0034] In practical use, the agent used to purify the exhaust gas is first transported to the bottom of the treatment box 20 through the water inlet pipe 41 and the water inlet tank 40 for storage. Then, the exhaust gas to be purified is transported to the air inlet slot of the treatment box 20 through the air inlet pipe 23. When the exhaust gas passes through the air inlet slot of the treatment box 20, it directly enters the agent accumulated in the cavity of the treatment box 20. Then, it gradually moves from the bottom of the agent upwards. As the exhaust gas moves, the clumps of exhaust gas are separated into smaller clumps by each clump-forming plate 33 as it moves along the bottom slope of the guide plate 32. At this time, the exhaust gas comes into contact with the agent and reacts. Then, the exhaust gas gradually moves towards the through slot 31 along the bottom slope of the guide plate 32. Then it moves upward through the channel 31 and the motor power of the fan assembly 21 is turned on synchronously when conveying the exhaust gas. The fan assembly 21 can adsorb the exhaust pipe 22 in the treatment box 20. After the exhaust gas has come into contact with the agent, it will be guided upward through the channel 31 and pass through the activated carbon plate 35 due to the adsorption of the fan assembly 21. After the exhaust gas passes through the activated carbon plate 35, it will be adsorbed and filtered by the activated carbon plate 35, thus completing the treatment. Finally, it will be adsorbed by the fan assembly 21 and discharged from the treatment box 20 through the exhaust pipe 22. At this point, the exhaust gas treatment is completed. The agent in the treatment box 20 can be discharged by opening the valve of the drain outlet 24.

[0035] In summary, by setting up a gas filtration structure, the principle that the volume of gas is smaller than that of liquid can be utilized to allow the waste gas to pass through the reagent. The guide plate 32 extends the contact time between the waste gas and the reagent. In addition, the slugging plate 33 breaks down large clumps of waste gas, ensuring full contact between the waste gas and the reagent. Finally, the activated carbon plate 35 filters the waste gas, thus making this solution not only have high treatment quality but also high treatment efficiency.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the inlet tank 40 and the overflow tank 42 are rectangular tanks of the same size. The inlet tank 40 is located above the overflow tank 42 and is lower than the fixed plate 30. The inclined plate 44 is rectangular and is located on the inner wall of the treatment box 20 between the inlet tank 40 and the overflow tank 42. The inclined plate 44 is inclined downwards. The baffle 45 is rectangular and is located on one side of the through channel 31. The baffle 45 is close to the inclined plate 44. The recycling structure also includes an inlet pipe 41, an overflow pipe 43, and a storage box 46. The inlet pipe 41 is fixedly connected to the inlet tank 40. On the outer wall of the treatment box 20 at position 0, the overflow pipe 43 is fixedly connected to the side wall of the treatment box 20 at the overflow trough 42, and the storage box 46 is fixedly connected to the wall of the treatment box 20 on the same side as the overflow pipe 43. The water inlet pipe 41 is an L-shaped hollow rectangular tube, and the lower end of the water inlet pipe 41 can be connected to the water inlet trough 40. The overflow pipe 43 is an inverted L-shaped hollow rectangular tube, and the upper end of the overflow pipe 43 can be connected to the overflow trough 42. The storage box 46 is a hollow rectangular box with an open top, and the lower end of the overflow pipe 43 can be aligned with the top of the cavity of the storage box 46.

[0037] In actual use, when the agent enters the treatment tank 20 through the water inlet pipe 41 and the water inlet tank 40, the agent will slide down from the top of the inclined plate 44 and accumulate in the treatment tank 20. When the agent level gradually rises above the overflow tank 42, the agent will leak out from the overflow tank 42 and accumulate in the storage tank 46 through the overflow pipe 43.

[0038] In summary, by setting up a recycling structure, the overflow trough 42 can be used to prevent the reagent from overflowing into the treatment tank 20, thereby effectively improving the stability of the device during operation.

[0039] Working principle: First, the reagent used to purify the waste gas is transported to the bottom of the treatment tank 20 through the inlet pipe 41 and the inlet tank 40 for storage. Then, the waste gas to be purified is transported to the inlet slot of the treatment tank 20 through the inlet pipe 23. As the waste gas passes through the inlet slot of the treatment tank 20, it directly enters the reagent accumulated in the treatment tank 20 and then gradually moves upward from the bottom of the reagent. As the waste gas moves, the clumps of waste gas are separated into smaller clumps by each clump-forming plate 33 as it moves along the bottom slope of the guide plate 32. At this time, the waste gas comes into contact with the reagent and reacts. Then, the waste gas moves along the guide plate 32. The bottom slope gradually moves towards the through groove 31, and then moves upward through the through groove 31. When conveying the exhaust gas, the motor power of the fan assembly 21 is turned on simultaneously. The fan assembly 21 can adsorb the exhaust gas in the treatment box 20 cavity towards the exhaust pipe 22. After the exhaust gas has come into contact with the agent, it passes through the through groove 31 and is guided upward by the adsorption of the fan assembly 21 and passes through the activated carbon plate 35. After the exhaust gas passes through the activated carbon plate 35, it is adsorbed and filtered by the activated carbon plate 35, thus completing the treatment. Finally, it is adsorbed by the fan assembly 21 and discharged from the treatment box 20 cavity through the exhaust pipe 22. Thus, the exhaust gas treatment is completed.
