[0003] The current biological filter tank box structure is relatively simple, and the following problems exist in the actual use process:

[0004] 1. The air inlet of the box body is correspondingly arranged with the filter material layer filled in the interior, so that the waste gas always contacts the fixed position of the filter material layer during the entering process, which is not convenient for the uniform diffusion of the waste gas, and also makes the waste gas flow in a relatively fixed flow channel, which has an adverse effect on the subsequent degradation and treatment of the waste gas;

[0005] 2. The biological filter tank body is usually provided with a spraying pipeline, and the spraying pipeline directly sprays liquid to the filter material layer, which causes the filter material layer to be subjected to a large impact force, which not only has an adverse effect on the biological filter membrane on the surface of the filter material layer, but also affects the stability of the filter material layer structure;

[0006] 3. The current biological filter tank body usually uses a glass steel inner plate and a carbon steel framework as the main structure, and the glass steel plate is opaque, so that the spraying condition cannot be observed by the staff during the spraying process, and the problem of the internal spraying pipeline cannot be found in time when it affects the treatment efficiency of the equipment;

[0007] Therefore, there is an urgent need for a biological filter tank body structure that can overcome the above problems. UTILITY MODEL CONTENTS

[0031] In the process of deodorizing waste gas, the waste gas enters the tank body 2 through the air inlet 9, because the air inlet 9 is located in the lower part of the filter material layer 5, the waste gas first diffuses in the lower part of the filter material layer 5 and then floats upward into the filter material layer 5, so that the filter material layer 5 can be fully utilized, in the process of using the biological filter in daily life, the atomized liquid sprayed by the spray pipeline 4 is sprayed upward, and then the liquid naturally falls on the filter material layer 5, effectively reducing the impact force of the liquid on the filter material layer 5, ensuring the stability of the structure of the filter material layer 5, and providing strong support for the degradation of microorganisms.
