Gas purification device for paint drying equipment

Abstract

The invention discloses a gas purification device for paint drying equipment. The gas purification device comprises a cylindrical shell and a rotating cylinder, a gas inlet pipe is arranged at one end of the shell, the other end of the shell is a gas outlet end, one side of the shell is a heat conduction area, other parts of the shell are non-heat conduction areas, and the heat conduction area is made of a material with better heat conduction performance than that of the non-heat conduction areas; the rotating cylinder is rotationally arranged in the shell through a rotating shaft and is close to the gas inlet end, the rotating shaft is located on the axis of the shell, the interior of the rotating cylinder is divided into a plurality of mutually independent fan-shaped sealed spaces through a plurality of partition plates, the sealed spaces are filled with magnetic fluid, a semicircular shielding plate is arranged below the rotating cylinder, the shielding plate is located on the side close to the heat conduction area and is made of a non-heat-conduction material, and a permanent magnet is arranged on the outer side of the shell. A part of heat of the gas is absorbed by the magnetic fluid and is finally converted into kinetic energy of the rotating cylinder, so that the problem of the gas is solved, and subsequent filtering treatment is facilitated.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and in particular relates to a gas purification device for paint drying equipment. Background technique [0002] The use of paint is very common, and it also plays an increasingly important role in our life and work. Paint needs to be dried after use. During the drying process of the paint drying equipment, a large amount of toxic gas is generated by the volatilization of the paint, which needs to be purified by the corresponding gas purification device. The main toxic component in the paint volatilized gas is formaldehyde, which is generally purified by activated carbon adsorption. [0003] Different from the toxic gas produced by the direct volatilization of paint, the gas produced during drying has a high temperature and contains a lot of heat; it directly reacts with activated carbon, which will affect the adsorption efficiency of activated carbon; The cumbersome cost is high, and a...
