[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , in an embodiment of the present invention, a biological deodorization device for waste gas includes a first filtration box 1. A second filtration box 2 is integrally formed at the top of the first filtration box 1. A partition box 3 is integrally formed at the center of the first filtration box 1. A first biological filling layer 4 is installed between one side of the partition box 3 and the inner wall of the first filtration box 1. A second biological filling layer 5 is installed inside the second filtration box 2. The inner cavity of the first filtration box 1 is filled with a flushing liquid whose top surface is higher than the bottom plate of the partition box 3. One side bottom end of the first filtration box 1 is connected to a spraying assembly extending to the tops of the first biological filling layer 4 and the second biological filling layer 5. The other side of the first filtration box 1 is communicated with an air inlet pipe 6. The top end of one side of the second filtration box 2 is communicated with an air extraction assembly.

[0019] During use, the waste gas to be treated enters the interior of the first filtration box 1 from the air inlet pipe 6. After being filtered by the first biological filling layer 4, the waste gas continues to rise, passes through the second biological filling layer 5, and is then extracted by the air extraction assembly. It can effectively remove the odor in the waste gas. And there is a spraying assembly for spraying to the top of the biological filling layer, which can facilitate further filtration of the waste gas. The air extraction assembly extracts the waste gas from the interior of the filtration box, which can facilitate improving the filtration efficiency of the waste gas.

[0020] In one embodiment, specifically, the spraying assembly includes that the bottom end on one side of the first filtration box 1 is communicated with a water extraction pump 8 through a water extraction pipe 7. The output end of the water extraction pump 8 is communicated with a first water spraying pipe 9 extending to the top of the second biological filling layer 5. The first water spraying pipe 9 is communicated with a second water spraying pipe 10 extending to the top of the first biological filling layer 4. When the water extraction pump 8 is started, the water extraction pump 8 uses the water extraction pipe 7, the first water spraying pipe 9, and the second water spraying pipe 10 to pump the flushing liquid inside the first filtration box 1 to the top of the biological filling layer for spraying and filtration. The sprayed water can flow back to the bottom of the first filtration box 1 for recycling after being filtered.

[0021] Among them, filter plates 11 higher than the flushing liquid are installed between both sides of the partition box 3 and the inner wall of the first filtration box 1. The air inlet pipe 6 is installed on the top of the filter plate 11. When the water flowing downward after being sprayed passes through the filter plate 11 for filtration, the actual filtration effect of the flushing liquid can be improved.

[0022] In one embodiment, specifically, the air extraction assembly includes an air extraction pipe 12 communicating with the second filter box 2. The end of the air extraction pipe 12 is communicated with a fan 13. The output end of the fan 13 is communicated with a filtration assembly through an air outlet pipe 14. When the fan 13 is started, the fan 13 uses the air outlet pipe 14 and the air extraction pipe 12 to quickly send the exhaust gas after filtration inside the second filter box 2 to the filtration assembly for further filtration and purification.

[0023] Specifically, the filtration assembly includes a purification box 15 communicating with the air outlet pipe 14. Inside the purification box 15, a primary filter screen 16, a secondary filter screen 17 and a tertiary filter screen 18 are sequentially arranged in the direction away from the air outlet pipe 14. One side of the purification box 15 away from the air outlet pipe 14 is communicated with an exhaust pipe 19. Among them, the primary filter screen 16 is made of fiberglass filter material, the secondary filter screen 17 is made of activated carbon filter material, and the tertiary filter screen 18 is made of polyester fiber filter material, which can effectively improve the filtration effect on the exhaust gas and prevent harmful gases from diffusing into the air and polluting the environment.
