Spraying line VOCs waste gas treatment device

Abstract

The invention discloses a spraying line VOCs waste gas treatment device which comprises a spraying box body, a flow guide mechanism, a supporting platform, circular supporting through pipes, a catalytic decomposition mechanism and a flow guide cover. Supporting legs are arranged at the bottom of the spraying box body, and the flow guide mechanism is arranged in the spraying box body. The supporting platform is arranged at the top of the spraying box body; a pair of the circular supporting through pipes are arranged at the upper part of the supporting platform; the flow guide cover is arranged between the flow guide mechanism and the circular supporting through pipes; the catalytic decomposition mechanism is arranged on the upper portions of the circular supporting through pipes and connected with a centrifugal fan through a pipeline. Organic waste gas and paint mist volatilized by a spraying line are effectively separated, the waste gas is subjected to segmented treatment and catalytic decomposition, the flow of the treated waste gas is large, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, in particular to a VOCs waste gas treatment device for a spraying line. Background technique [0002] At present, the ductility of the aluminum sheet is excellent, and the aluminum sheet is often rolled into a thin plate structure in industrial production, such as brushed aluminum coils and painted aluminum coils. In the production process of Caihui aluminum coil, the aluminum coil needs to be dyed by paint spraying equipment, but for the existing aluminum coil spraying process, there are the following major technical problems: 1) If the existing spraying device is used for aluminum After spraying, the drying speed is slow. During the spraying process, the volatilized organic waste gas in the paint is under the action of the induced draft fan, and the paint mist is also mixed with the air flow and the volatilized organic waste gas, which makes the organic waste gas treatment process c...

Problems solved by technology

In the production process of Caihui aluminum coil, the aluminum coil needs to be dyed by paint spraying equipment, but for the existing aluminum coil spraying process, there are the following major technical problems: 1) If the existing spraying device is used for aluminum After spraying, the drying speed is slow. During the spraying process, the volatilized organic waste gas in the paint is under the action of the induced draft fan, and the paint mist is also mixed with the air flow and the volatilized organic waste gas, which makes the organic waste gas treatment process complicated. 1. It is difficult to purify and treat organic waste gas; 2) In time, the drying equipment is added in the prior art to accelerate the drying of paint, but the heat of heating makes the organic waste gas in the paint volatilize faster, and the flow rate of organic waste gas is large, and the treatment time is long
