Spraying drying room

Abstract

The invention discloses a spray drying room. The spray drying room is provided with an air supply system and a waste gas treatment system as a whole. The air supply system comprises a fresh air box fixedly connected to one side of the spray drying room, the fresh air box is equipped with a fresh air inlet and an air supply outlet communicated with the inside of the spray drying room, and an air supply fan equipped with a heating unit is arranged between the fresh air inlet and the air supply outlet. The waste gas treatment system comprises a paint mist filtering box and a waste gas purifying box which are fixedly connected to the other side of the spray drying room in sequence, the paint mist filtering box is equipped with a paint mist filtering inlet communicated with the inside of the spray drying room and a paint mist filtering outlet communicated with the waste gas purifying box body, and at least two stages of filtering sections are arranged between the paint mist filtering inletand the paint mist filtering outlet; and an adsorption module and an adsorption fan are arranged in the waste gas purifying box, the adsorption module is located between an air inlet of the adsorptionfan and the paint mist filtering outlet, and an air outlet of the adsorption fan is communicated with an adsorption purification discharging pipeline.

Description

technical field [0001] The invention belongs to the field of painting and industrial waste gas purification, and in particular relates to a spray drying room integrated with a waste gas treatment device. Background technique [0002] In recent years, the emission of volatile organic compounds (VOCs) is very large and has attracted widespread attention. There are many industries that produce VOCs, such as petrochemical, painting, ink printing, electronics, rubber products, etc. Among them, the VOCs produced by the painting industry account for about one-third, and small painting workshops for automobile maintenance are also part of the painting industry. With the accelerated development of my country's economy and the growth of people's material needs, cars are gradually becoming popular in families, and the number is still increasing. The paint mist and exhaust gas pollution generated by the painting operation during automobile maintenance must be treated. [0003] The sp...
