Description

Air purification device for steel plate paint spraying

Background

In order to maintain the aesthetic appearance and extend the service life of the steel sheet, painting operations are required to be performed on the surface of the steel sheet after the steel sheet product is finished.

Paint mist and organic waste gas pollution are mainly generated in the paint spraying process. The paint is atomized into particles under the action of high pressure, and when the paint is sprayed, part of the paint does not reach the surface of a painted object and is dispersed with air flow to form paint mist. The diluent (organic solvent) is used to dilute the paint for the purpose of achieving a smooth appearance of the paint surface. The organic solvent is easy to volatilize gradually in the process of paint spraying and air drying to form organic waste gas. Benzene, toluene and xylene which are organic solvents in the paint mist belong to highly toxic solvents, are emitted into air of a workshop during operation, and can cause acute and chronic poisoning after workers inhale through respiratory tracts, mainly cause damage to a central nervous system and a hematopoietic system, and cause aplastic anemia by inhaling high-concentration benzene vapor for a short time; the frequent inhalation of low-concentration benzene vapor can also cause nausea, leaf vomiting, mental confusion and other neurological symptoms, and a few can also cause neurasthenia syndrome, so that the development of an air purification device for steel plate paint spraying is urgently needed to overcome the defects in the current practical application.
