Furniture spray paint waste gas treatment apparatus

Abstract

The invention relates to a furniture spray paint waste gas treatment apparatus. The furniture spray paint waste gas treatment apparatus comprises a dry-type filter (2), a molecular sieve adsorption bed (4), a VOCs online monitoring instrument (5), a main fan (7), an exhaust cylinder (8), a PLC control system (9), a catalytic combustion bed (11) and a desorption fan (12); after paint particles in the waste gas are removed, the organic waste gas enters the dry-type filter, the waste gas with the paint mist and dust being removed enters the molecular sieve adsorption bed, volatile organic compound in the molecular sieve adsorption bed is adsorbed onto a porous surface of a molecular sieve, and the purified gas is discharged to high altitude in an up-to-standard manner by virtue of a main fanand the exhaust cylinder from an outlet of the molecular sieve adsorption bed; and the VOCs adsorbed in the molecular sieve adsorption bed enters the desorption fan and is desorbed by virtue of the blowing of hot air, and the desorbed VOCs enters the catalytic combustion bed to be catalytically oxidized and decomposed. The furniture spray paint waste gas treatment apparatus is suitable for treating low-concentration organic waste gas, and is good in treatment effect and easy in control.

Description

technical field [0001] The invention belongs to the field of VOCs waste gas treatment, and in particular relates to a treatment device for waste gas from spray painting in the furniture industry. Background technique [0002] With the continuous development of my country's manufacturing industry, the output and types of its follow-up products are increasing year by year. In the process of production, storage, transportation and use, the waste gas generated contains a certain amount of various organic substances, which are directly discharged into the atmosphere. Seriously Polluting the environment, the volatile organic compounds (Volatile Organic Compounds VOCs for short) can participate in photochemical reactions and form photochemical smog. Especially in the furniture spraying industry, the emission of industrial VOCs continues to increase, and has become one of the main causes of air pollution in urban agglomerations and local areas in my country. Therefore, the pollution...
