Paint mist removal method of paint booth using micro bubble

摘要

Problem to be solved: to provide a paint mist removing method of a paint booth using a microbubble having high adsorption and decomposition functions of paint mist and VOC contained in a coating booth exhaust and high decomposition ability of paint sludge and VOC in a paint sludge processing tank.Solution: Venturi in a paint mist collecting chamber which discharges a micro bubble generated by a micro bubble generating means into a paint booth circulating water in a paint sludge processing vessel of a paint booth, adjacent to a paint space of a paint booth and disposed above a paint sludge processing tank The paint booth exhaust water and the paint booth circulating water are discharged from the paint booth circulating water, and the paint mist in the paint booth exhaust is contacted into the paint booth circulating water spray, and spray paint circulating water is sprayed in the paint mist collection room.The paint mist in the paint booth exhaust is brought into contact with fine particles of the sheath circulating water.Diagram
