VOC biological breathable purifier and purifying method

Abstract

The invention relates to the field of waste gas treatment, in particular to a VOC biological breathable purifier and a purifying method and aims to treat volatile gas generated during spraying treatment of an injection molding product. A process of combining a spraying tower with a biological filler tower is adopted to treat spraying waste gas. Equipment is simple, extra adding of assistant treatment agents is not needed, and construction cost is low; the VOC biological breathable purifier is simple to operate, low in energy consumption, low in running cost, good in treatment effect, free of secondary pollution and high in safety.

Description

technical field [0001] The invention relates to the field of waste gas treatment equipment, in particular to a VOC biological breathable purifier and a purification method. Background technique [0002] VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). In actual production, VOC gas is mainly volatile gas generated during the processing of products that require spraying treatment. It mainly comes from the use of raw and auxiliary materials containing VOCs in paint, isobutanol, anti-white water and boiled oil water in the spraying process. The organic waste gas from painting is mainly generated in the stages of paint mixing, painting and drying. Further, the main components of the paint are acrylic resin, ethyl acetate, butyl acetate, cellulose, ethylene additives, pigments; Ethanol (ethylene glycol butyl ether). [0003] The main treatment methods for VOC waste gas at this stage are as follows: [0004] 1. If the amount is small, ...

Problems solved by technology

[0004] 1. If the amount is small, discharge directly to the outside;

[0005] 2. If the amount is large, use the way of biological packing tower to decompose

[0006] However, in the prior art, the air purification effect is mostly unsatisfactory, especially because the equipment is huge, the degree of automation is low, there are many inconveniences in the use process, there are potential safety hazards, and a lot of working hours are consumed.

At the same time, with the substantial improvement of national standards, the standards for environmental protection standards have been increased year by year, and the current technology is becoming more and more difficult to meet the work requirements.
