A biological deodorization filter with a fiberglass sandwich composite panel structure

Abstract

This utility model discloses a biological deodorization filter with a fiberglass sandwich composite panel structure, relating to the field of biological deodorization technology. It includes: a foundation, with a filter tank body fixedly connected to the top of the foundation. The outer wall of the filter tank body has an observation window. The filter tank body includes a support plate, which comprises a carbon steel corrosion-resistant profile. An outer fiberglass plate and an inner fiberglass plate are fixedly connected to both sides of the carbon steel corrosion-resistant profile. A stainless steel plate is fixedly connected to the outer wall of the outer fiberglass plate. Insulation cotton is fixedly connected between the outer and inner fiberglass plates. The insulation cotton between the outer and inner fiberglass plates, combined with the overall sealed structure, effectively reduces heat exchange between the inside and outside of the filter tank, ensuring stable operation of the equipment in low-temperature environments. This avoids the decrease in microbial activity caused by low temperatures and reduces the shortcomings of traditional equipment where insufficient insulation affects deodorization efficiency.

Description

Technical Field

[0001] This utility model relates to the field of biological deodorization technology, specifically to a biological deodorization filter with a fiberglass sandwich composite panel structure. Background Technology

[0002] Odors are volatile gases whose molecules diffuse in the air, corroding mechanical equipment. When inhaled, they cause an unpleasant odor sensation. To reduce the concentration of odors during equipment operation, it is required to deodorize wastewater and sludge facilities that generate odorous gases to ensure that the treated exhaust gas meets emission standards. Existing biological deodorization filters mostly use single-material shells or simple composite structures, which have significant drawbacks: while traditional carbon steel frames provide a certain strength, they lack sufficient insulation measures in the design, making it impossible to ensure uninterrupted operation of the equipment year-round. In summary, to solve the above problems, improve the efficiency and quality of biological deodorization, and reduce losses, this utility model has emerged. Utility Model Content

The foundation 1 provides stable support for the filter tank 2. The filter tank 2 achieves overall structural strength through the support plate 22. The stainless steel plate 221 is located on the outside to resist external corrosion. The outer fiberglass plate 222 and the inner fiberglass plate 225 sandwich the insulation cotton 224. The rigidity is enhanced by the carbon steel anti-corrosion profile 223. The internal working condition can be viewed in real time through the observation window 3 to ensure stable operation of the filter tank in complex environments and meet the long-term deodorization treatment needs.

The treated gas is discharged upwards, and the waste liquid permeates into the sewage tank 26 for collection. The inner fiberglass plate 225 provides installation conditions for the filter structure 25. The sewage tank 26 temporarily stores the waste liquid for subsequent treatment, forming a complete gas-liquid treatment cycle.

The organic composite filter material 252 adsorbs small molecule malodorous substances, and the inorganic composite filter material 253 enhances the mass transfer efficiency. The two work together to improve the deodorization effect. The treated gas is discharged through the upper space.

[0021] Working principle:

[0022] During use, the foundation 1 provides stable support for the filter tank 2. The filter tank 2 achieves overall structural strength through the support plate 22.

The top cover plate 21 seals the top of the filter tank 2. The base 23 is tightly connected to the foundation 1. The liquid sprayed from the nozzles 24 on the inner wall of the support plate 22 acts evenly on the filtration structure 25, and after treatment... The gas is discharged upwards, and the waste liquid permeates into the sewage tank 26 for collection. The inner fiberglass plate 225 provides installation conditions for the filter structure 25. The sewage tank 26 temporarily stores the waste liquid for subsequent treatment, forming a complete gas-liquid treatment cycle. In the filter structure 25, the filter grid 251 is fixed on the inner fiberglass plate 225 of the support plate 22, supporting the upper organic composite filter material 252 and inorganic composite filter material 253.
