Description

Technical Field

[0001] The utility model relates to the technical field of waste gas deodorization, in particular to an industrial waste gas deodorization biological filter tank structure. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in enterprise factories. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, lead and mercury, beryllium, smoke and industrial dust. When discharged into the atmosphere, it will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have a cumulative effect, which will more seriously endanger human health. Different substances will have different effects. Industrial waste gas generally needs to be treated before it can be discharged.

[0003] For example, a Chinese patent (CN216630329U) discloses an industrial waste gas deodorization biological filter structure, including a filter, a main inspection port and a side inspection port, the main inspection port and the side inspection port are respectively installed on the front side and the left side of the upper end of the filter, a packing bed assembly is arranged inside the filter, and the packing bed assembly includes a main spray pipe, a main nozzle, a composite filler, a biological deodorization section, a multi-faceted hollow ball filler and a pre-washing section, and the composite filler is stored above the interior of the biological deodorization section. The industrial waste gas deodorization biological filter structure, through the cooperation between the pre-washing section, the air distribution pipe, the air inlet, the air outlet pipe, the main spray pipe and the composite filler, the air flow enters the biological deodorization section from the air outlets on the front and rear sides of the pre-washing section along the externally arranged air distribution pipe, so as to achieve the purpose of purifying the waste gas, and the outlet branch pipes are finally gathered into the outlet pipe, avoiding the problems of complex arrangement of the filtering structure in the prior art, low removal efficiency, need for special maintenance and high investment cost.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for cooling and removing impurities from the waste gas. Since the waste gas generated in industrial production often carries a large amount of heat and solid impurities, if the heat in the waste gas is not removed in advance, it will enter the filter tank, thereby causing the filter tank to heat up, making it impossible for microorganisms to produce and reproduce at a suitable temperature, which will lead to a reduction in the effect of biological deodorization. At the same time, solid impurities will accumulate on the surface of the composite filler and require frequent cleaning. Based on this, an industrial waste gas deodorization biological filter tank structure is proposed. Utility Model Content
