Treatment process of UV oil paint spraying exhaust gas

Abstract

The invention relates to a treatment process of ultraviolet (UV) oil paint spraying exhaust gas, and belongs to the technical field of environment protection. A cyclone centrifugal spraying tower is connected with a circulating water tank; an air inlet is formed in one end of the cyclone centrifugal spraying tower; the top part of the cyclone centrifugal spraying tower is connected with a centrifugal blower; the other end of the centrifugal blower is mutually matched with one end of a demisting filter cabinet while the other end of the demisting filter cabinet is mutually matched with an activated carbon adsorption cabinet; an outlet of the activated carbon adsorption cabinet is connected with a sampling platform; the two ends of a catalytic combustion device are mutually connected with the two ends of the activated carbon adsorption cabinet; a discharge hole is formed in the outer side of the sampling platform. The occupied area of the whole project is small, the space utilization rate is high, and manual operation is simple and convenient; moreover, the treatment process disclosed by the invention has the advantages of a stable effect, complete removal of exhaust gas pollutants, convenient operation, flexible operation and the like.

Description

technical field [0001] The invention relates to a process for treating waste gas from UV paint spraying, and belongs to the technical field of environmental protection. Background technique [0002] There are two main components of UV paint exhaust gas: paint mist and VOC. Among them, paint mist is in liquid state and VOC is in gaseous state. UV paint mist contains a large amount of paint mist particles, and is highly viscous. Generally, exhaust gas treatment facilities are located on the roof. The paint mist molecules in UV paint exhaust gas are quickly cured by sunlight, which brings difficulties to the maintenance of exhaust gas treatment facilities. . Therefore, the separation and removal of paint mist molecules is the core of the whole exhaust gas treatment process. If the paint mist problem is not solved, the subsequent VOC treatment facilities will not be able to operate normally. Contents of the invention [0003] The object of the invention is to provide a kind ...

AI Technical Summary

Problems solved by technology

UV paint mist contains a large amount of paint mist particles, and is highly viscous. Generally, exhaust gas treatment facilities are located on the roof. The paint mist molecules in UV paint exhaust gas are quickly cured by sunlight, which brings difficulties to the maintenance of exhaust gas treatment facilities.

Therefore, the separation and removal of paint mist molecules is the core of the entire waste gas treatment process. If the paint mist problem is not solved, the subsequent VOC treatment facilities will not be able to operate normally.
