Description

Technical Field

[0001] This utility model belongs to the field of biological trickling filtration technology, specifically a biological trickling filtration device. Background Technology

[0002] A bio-trickling filtration system is an environmental treatment device that utilizes the metabolic processes of microorganisms to degrade pollutants (organic matter and malodorous substances in waste gas or wastewater). Through microbial metabolism, volatile organic compounds (VOCs), hydrogen sulfide, ammonia, and other substances in waste gas are broken down into harmless carbon dioxide, water, and inorganic salts. For example, in odor control at paper mills, the removal rate of hydrogen sulfide exceeds 94%, and the removal rate of ammonia exceeds 90%.

[0003] In the existing technology, bio-trickling filters purify gases using packing material. However, the packing material needs to be dripped during gas purification to ensure the growth of microorganisms in the packing. But the packing material is prone to clumping during the spraying operation, which affects the purification effect of the packing.

[0004] Therefore, this utility model provides a biological trickling filter device. Utility Model Content

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The bio-trickling filter device of this utility model allows gas to enter through the inlet pipe, be purified by the packing material, and then be sprayed out through the outlet pipe. At the same time, the liquid outlet pipe facilitates the flow of liquid for recycling. The packing material can be replaced and intermittently shaken back and forth to avoid clumping.

[0016] 2. The biological trickling filter device of this utility model, when it is necessary to shake the packing box, the servo motor drives the disc and pin to rotate, thereby pushing the U-shaped plate to move left and right. Then, through the connection of the fixed shaft and the through shaft, the packing box is shaken left and right. At the same time, the partition plate can facilitate the shaking of the entire packing and avoid clumping. At the same time, the first cover box and the second cover box are provided on the left and right to effectively prevent gas from escaping. When it is necessary to replace the packing in the packing box, the second cover box and the cover plate are opened to remove the first bolt, thereby disengaging the fixed shaft and the through shaft, allowing the packing box to be taken out from the through groove for packing replacement. Then, the packing box is placed in the through groove, and the through shaft is inserted into the first cover box and connected to the fixed shaft through the first bolt. Then, the second cover box and the cover plate are installed to complete the replacement operation. The packing in the packing box is organic natural packing and inorganic artificial packing, which will not be described in the prior art. At the same time, the shaking of the packing box is only intermittent, not continuous. Attached Figure Description
