It cannot be discharged directly into the atmosphere and must be treated first.

[0003] After searching, Chinese patent announcement number: CN217119373U discloses a microbial fermentation tail gas treatment device, which uses a condensing plate to impedance the waste gas generated by fermentation, while increasing the contact area between the steam and the cavity, improving the heat exchange efficiency to achieve the purpose of condensing steam, and a water storage tank partition plate connected to the condensing plate is set inside the water storage tank, so that the steam condenses and enters the water storage tank through the condensation water inlet along the slope, and then flows into the bottom of the water storage tank along the water storage tank partition plate, so as to reduce steam discharge while collecting wastewater; the residual waste gas will enter the final filter device through the through hole, and the filter device will absorb the residual culture medium steam and odor to achieve the purpose of purification.

[0004] The above-mentioned device has the following defects. When microorganisms are fermenting, they will decompose organic matter and produce a large amount of metabolites. These will combine with the nutrients in the raw materials to form fermentation residue. When the fermentation residue follows the steam and enters the interior of the device, because several condensation plates are trumpet-shaped, most of the residue will adhere to the condensation plates. When the device is cleaned, some of the residue in the gaps may not be cleaned well. During long-term use, the device may be corroded, reducing the service life of the device. For this reason, a biotrickling filter is proposed for a fermentation exhaust gas treatment device to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution: the end of the spring damper away from the spring damper is clamped on the outer wall of one side of the movable frame, and the abutment plate is slidably connected to the inner walls on both sides of the sliding groove.

[0009] As a further description of the above technical solution: the threaded barrel is threadedly connected to the inner wall of the side of the processing tank, and the outer wall of the side of the abutment plate is fixedly connected with a wear-resistant pad.
