Air purifying device for paint mixing room

Abstract

The invention provides an air purifying device for a paint mixing room. The air purifying device comprises a tank body, wherein an air inlet is formed in the right side of the tank body, and an air outlet is formed in the left side of the tank body; an inner cavity of the tank body is divided into a right processing cavity and a left power cavity by a partition board; a coarse filtration net, a light-emitting assembly, a photocatalyst and an middle filtration net are sequentially arranged in the processing cavity from right to left, and an exhausting machine is arranged in the power cavity; and the light-emitting assembly comprises a power distribution tank and a plurality of purple light tubes, the power distribution tank is arranged on the front side of the processing cavity, and the purple light tubes are arranged on the rear side of the power distribution tank. By virtue of respective filtration absorption, photo-catalytic oxidation decomposition and filtration absorption of the coarse filtration net, a photocatalyst plate and the middle filtration net which are sequentially arranged, filtered gas can meet the requirement on the direct indoor emission, so that the labor environment of workers is protected.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an air purification device for a paint mixing room. Background technique [0002] The air in the paint mixing room contains toxic substances such as benzene, toluene, xylene, ethyl acetate, butyl acetate, acetone, etc., which mainly come from the volatilization of diluents in the paint blending process; the above-mentioned toxic substances exist in the form of gas, of which benzene It is a highly toxic substance, which can cause death in large doses; toxic substances can enter the body of workers through breathing, skin contact and other channels. [0003] In the existing technology, a separate fan is used to transport the air in the paint mixing room to the large system for unified treatment. Usually, due to the design selection or the mismatch of pipeline resistance, the processing air volume of the paint mixing room cannot reach the design. As a res...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an air purification device for a paint mixing room, through the filtration and adsorption of the coarse filter set in sequence, the photocatalytic oxidation decomposition of the photocatalyst plate and the filtration and adsorption of the middle filter, so that the treated gas It meets the requirements of being able to be discharged directly into the room and protects the working environment of workers; it solves the problem that the processing air volume of the paint mixing room cannot meet the design requirements and the concentration of harmful substances in the room exceeds the standard due to the mismatch of design selection or pipeline resistance in the prior art And other issues
