Description

TECHNICAL FIELD [0001] The present invention relates to a particulate matter and volatile organic compound treating system for automotive paint coating,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a particulate matter and volatile organic compound treatment system for use in automotive paint applications and, more particularly, to a particulate matter and volatile organic compounds Volatile organic compounds (VOCs), and odor-effectively removing particulate matter and volatile organic compound treatment systems for automotive coating applications.

Generally, in automobile repair booths and other various painting equipment used for painting automobiles and their accessories in an automobile maintenance factory or a transportation company, painting and drying work for the articles are alternately performed. In addition to the particulate matter such as paint mist scattered during the painting process, the organic solvent contained in the paint stream is volatilized into the air during the drying process of the painted article, and various volatile organic compounds such as toluene Is contained in a large amount in the air inside the painting equipment.

When such volatile organic compounds are released into the atmosphere as they are, the volatile organic compounds react with light to generate photochemical oxides such as ozone, nitrogen compounds in aldehydes or smog, thereby causing environmental pollution such as photochemical smog and global warming in large cities In addition, most of the volatile organic compound substances cause irritation and unpleasant odor even at low concentrations. They are carcinogens that cause skin disorders such as nervous system when they come into contact with human skin or respiratory system. Recently, Legal emissions regulations are being set up for facilities.

Particularly, in paint coatings such as automobile paint booths, paint mist can be easily removed by using various filters in the case of paint polluting materials. However, in the case of volatile organic compounds generated by volatilization of organic solvents in paint components Since the exhaust air flow rate during painting is medium and large, the processing is relatively complicated due to factors such as economical efficiency.

To solve this problem, particulate matter and volatile organic compounds precipitated by filling the water at the bottom of the painting booth are removed, or a filtering filter is installed on the entire bottom surface to treat the particulate matter, and then a separate activated carbon adsorption device is installed outside It has become common to treat volatile organic compounds.

An example of such a volatile organic compound processing apparatus for painting equipment is disclosed in Korean Utility Model Registration No. 20-0280005 (registered on June 17, 2002, hereinafter referred to as Patent Document 1).

However, according to the prior art, when the volatile organic compound is treated by sedimentation in a state filled with water, a high concentration of wastewater can be generated, resulting in secondary environmental pollution, and a filtration filter In addition, when a separate activated carbon adsorption apparatus is installed outside, the treatment efficiency of the particulate matter and the volatile organic compound may be lowered, and a large installation area may be required, and maintenance may also be difficult.
