[0019] As Figures 1 to 4As shown, a water guide plate 2 is fixedly connected to the top of the biological filter tank 1. An external water pipe 21 is connected to the top of the water guide plate 2 and is fixedly connected to the biological filter tank 1. Multiple nozzles 22 are connected to the bottom of the water guide plate 2. A first partition 23 is provided on one side of the water guide plate 2 and is fixedly connected to the biological filter tank 1. An air vent plate 24 is fixedly connected to one side of the first partition 23. A second partition 25 is fixedly connected to one side of the air vent plate 24 and is fixedly connected to the biological filter tank 1. A drain pipe 26 is provided on one side of the second partition 25 and is connected to the biological filter tank 1. During operation, the first partition 23, air vent plate 24, and second partition 25 will... The biological filter tank 1 is divided into two areas. The air inlet 11 conducts odor into the biological filter tank 1, where it accumulates at the bottom of the water guide plate 2. The external water pipe 21 connects to the water source, and the nozzle 22 atomizes the water to spray the odor. This removes particulate matter from the odor and regulates humidity. The sprayed water accumulates on one side of the second partition 25, and excess water is discharged from the drain pipe 26.

[0020] like Figures 1 to 5 As shown, a horizontal plate 3 is fixedly connected to the middle of the exhaust pipe 19, and a first spring 31 is fixedly connected to the top of the horizontal plate 3. A float 32 is fixedly connected to the top of the first spring 31. The float 32 is slidably connected to the exhaust pipe 19. During operation, the odor needs to remain in the grid plate 12 for a period of time. Opening the exhaust pipe 19 is not conducive to the full decomposition of the odor. When the air pressure in the biological filter tank 1 is too high, it will push the float 32 up and stretch the first spring 31. At this time, the amount of odor being introduced into the biological filter tank 1 can be reduced. After the reaction in the biological filter tank 1 is sufficient, the odor will continue to be introduced into the biological filter tank 1. The air pressure in the biological filter tank 1 will increase, pushing the float 32 out, and the treated odor will be discharged.
[0021] like Figure 3 As shown, two second springs 4 are fixedly connected to the bottom of the slide groove 14, and a pad 41 is fixedly connected to the top of the second springs 4. The pad 41 is slidably connected to the second springs 4. When the locking block 15 is installed in the slide groove 14, it will press down on the pad 41, and the second springs 4 will be compressed. When the locking block 15 is pulled out of the slide groove 14, the elastic sheet 18 is released from the restraint of the locking groove 17, and the second spring 4 rebounds to lift the pad 41, thereby pushing the locking block 15 out of the slide groove 14. This makes it convenient to replace the filter screen 16.
[0022] like Figure 3As shown, a protective cloth 5 is provided on one side of the second spring 4. One end of the protective cloth 5 is fixedly connected to the slide groove 14, and the other end of the protective cloth 5 is fixedly connected to the pad 41. During operation, the protective cloth 5 protects the second spring 4, reduces the corrosion of the second spring 4 by substances in the odor, and extends the service life of the second spring 4.
[0023] like Figures 1 to 3 As shown, a sealing ring 6 is provided on the outer side of the card block 15. The sealing ring 6 is fixedly connected to the slide groove 14. During operation, the sealing ring 6 fills the gap between the slide groove 14 and the card block 15 to reduce the leakage of odor.
[0024] Working principle: The air inlet 11 is connected to an air pump to extract the odorous gas generated during yam processing. The gas enters the biological filter tank 1 through the air inlet 11 and is filtered by the filter screen 16. The filter screen 16 separates the impurities attached to the odorous gas. Then the odorous gas enters the biological filter tank 1. The grid plate 12 is filled with biological filter media, such as volcanic rock, activated carbon fiber, and modified plant fiber, which provides an attachment carrier for microorganisms. The odorous gas stays in the biological filter media and passes through. The microorganisms on the grid plate 12 target components such as hydrogen sulfide, ammonia, and VOCs. Targeted degradation is performed, and the treated gas is discharged from the exhaust pipe 19. The discharge pipe 13 discharges wastewater from microbial metabolism on the grid plate 12. The filter screen 16 can be replaced. The locking block 15 is placed in the slide groove 14, and the elastic sheet 18 is compressed by the slide groove 14. The locking block 15 slides in the slide groove 14 until the locking groove 17 and the elastic sheet 18 are aligned. The elastic sheet 18 then springs back and locks into the locking groove 17. When removing it, the locking block 15 is pulled outward, and the elastic sheet 18 is compressed by the pressure of the corner of the locking groove 17. Then, remove the card block 15 from the chute 14 and replace or clean the filter screen 16 on the card block 15; by setting up the biological filter tank 1, air inlet 11, grid plate 12, and discharge pipe 13, the various parts of the structure constitute a biological filter. By simulating the natural microbial degradation process, the odor generated during yam processing is converted into harmless substances. The filter screen 16 performs preliminary filtration of the odor entering the air inlet 11, reducing the number of impurity particles entering the biological filter tank 1 and affecting the microbial degradation efficiency on the grid plate 12. The first partition plate 23. The permeable plate 24 and the second partition 25 divide the biological filter tank 1 into two areas. The air inlet 11 conducts odor into the biological filter tank 1, where it gathers at the bottom of the water guide plate 2. The external water pipe 21 connects to the water source, and the nozzle 22 atomizes the water to spray the odor. This removes particulate matter from the odor and regulates the humidity. The sprayed water gathers on one side of the second partition 25, and excess water is discharged from the drain pipe 26. The treated odor passes through the permeable plate 24 into the area of the grid plate 12, where it is degraded by microorganisms.The biological filter tank 1 is divided into zones by setting a first partition 23, a permeable plate 24, and a second partition 25. A water guide plate 2, an external water pipe 21, and a nozzle 22 pre-treat the odor, thus improving the efficiency of odor degradation by microorganisms on the grid plate 12. The odor needs to remain within the grid plate 12 for a period of time; leaving the exhaust pipe 19 open is not conducive to the full decomposition of the odor. When the air pressure inside the biological filter tank 1 is too high, it will lift the float 32 and stretch the first spring 31. At this time, the amount of odor introduced into the biological filter tank 1 can be reduced. After the reaction in the biological filter tank 1 is sufficient, the odor continues to be introduced into the biological filter. Odor is introduced into tank 1, increasing the air pressure inside the biological filter tank 1. This pushes out the float 32, allowing the treated odor to be discharged. When the locking block 15 is installed in the slide chute 14, it presses down on the pad 41, compressing the second spring 4. When the locking block 15 is pulled out of the slide chute 14, the elastic sheet 18 disengages from the restraint of the locking groove 17, and the second spring 4 rebounds, lifting the pad 41 and pushing the locking block 15 out of the slide chute 14. This facilitates the replacement of the filter screen 16. The protective cloth 5 protects the second spring 4, reducing the corrosion of the second spring 4 by substances in the odor and extending its service life.
