An exhaust pipe is fixedly connected to a slot on the top of the tank cover 12. 13. Activated carbon plate 14 is connected to the exhaust pipe 13. The outside of slider 15 is slidably connected to the inner wall of slide groove 16. Multiple connecting blocks 17 are provided between the two activated carbon plates 14. A sealing sleeve 18 is provided on the outside of the end of exhaust pipe 13 away from the can cover 12. The two ends of the connecting block 17 are fixedly connected to the opposite side of the two activated carbon plates 14 respectively. The inner wall of the slot opened at the end of exhaust pipe 13 away from the can cover 12 is fitted with the sealing sleeve 18. A filter sleeve 19 is provided at the end of exhaust pipe 13 away from the can cover 12. A filter membrane 110 is provided inside the can body 11. Four limiting blocks 111 are fixedly connected to the outside of filter membrane 110 in a ring array. Four limiting grooves 112 are opened in a ring array on the inner wall of can body 11. The inner wall of filter sleeve 19 is threadedly connected to the end of air pipe away from can cover 12. The outside of limiting block 111 is slidably connected to the inner wall of limiting groove 112. An auxiliary mechanism 2 is provided on one side of can body 11.

[0025] In this embodiment, when it is necessary to purify the waste gas generated by Bacillus subtilis fermentation, the exhaust fan 34 can be started. The resulting airflow will draw the gas in the tank 11 into the exhaust pipe 13. The waste gas will undergo initial filtration through the filter membrane 110 before entering the exhaust pipe 13. Harmful substances in the waste gas will be adsorbed in the filter membrane 110. The waste gas can be purified and filtered by the two layers of activated carbon plates 14. The purified gas will be discharged to the outside through the filter sleeve 19. The sealing sleeve 18 ensures that the gas does not...

[0028] This utility model provides a waste gas treatment device for Bacillus subtilis fermentation, the specific working principle of which is as follows:

[0029] When treating the waste gas generated during the fermentation of Bacillus subtilis, a certain amount of acetic acid solution needs to be pre-stored in the storage tank 21. By starting the water pump 22 connected to the storage tank 21, the acetic acid solution in the storage tank 21 can be extracted and transported to the special storage pipe 23 through the pipeline. When the acetic acid solution flows through the atomizing nozzle 24, it will be converted into fine droplets and sprayed evenly into the tank 11 containing the waste gas. The purpose of this is to ensure that the acetic acid solution can fully contact and cover every space in the tank 11, thereby maximizing the absorption and neutralization of ammonia and reducing the number of microorganisms. By starting the exhaust fan 34, the airflow generated will draw the gas in the tank 11 into the exhaust pipe 13. The waste gas will be initially filtered through the filter membrane 110 before entering the exhaust pipe 13. The harmful substances in the waste gas will be adsorbed in the filter membrane 110. The waste gas can be purified and filtered through the two layers of activated carbon plates 14. The purified gas will be discharged to the outside through the filter sleeve 19.
