[0002] Fermentation tanks are needed in the process of manure fermentation. During the fermentation process, a certain amount of gas will be generated in the fermentation tank, especially in the early stage of fermentation, the amount of gas generated is often large. Therefore, it is necessary to perform corresponding pressure relief operations on the fermentation tank. After traditional pressure relief, the gas is usually discharged directly, affecting the nearby environment.

[0003] After searching, the Chinese patent document (authorization announcement number CN216404352U) discloses an automatic pressure relief enzyme fermentation tank, including a fermentation tank body; an automatic pressure relief mechanism is provided on the top of the fermentation tank body; the automatic pressure relief mechanism is composed of a connecting part, a filter part and an exhaust part that are interconnected; the bottom end of the connecting part is connected to the top of the fermentation tank body, and the top of the connecting part is connected to the bottom of the filter part; the filter part is large in the middle and small at both ends, and more than one layer of filter plates are provided in the inner cavity of the filter part, and a number of liquid-repelling holes are discretely arranged on the filter plate; a compression spring is provided in the upper part of the inner cavity of the exhaust part, the top of the compression spring is fixedly connected to the inner top wall of the exhaust part, the bottom end of the compression spring is connected to a plug part, and the outer circumferential surface of the plug part is in contact with the inner side wall of the exhaust part; an exhaust hole is provided on the side wall of the exhaust part. The fermentation tank can effectively avoid gas entrained with liquid and solid matter to block the exhaust hole during pressure relief, thereby ensuring the normal pressure relief. However, after the pressure relief, the depressurized gas is directly discharged, affecting the nearby environment. Utility Model Content

The deodorant sprayed from the spray bottle 8 can also deodorize the gas, and finally the gas is discharged from the connecting pipe.
