Abstract: Spraying coating has been extensively applied in the chemical engineering,automobile and ship industries. In the application process,the exhaust gas from spray paint process brought negative influences on environment and human health. This paper introduces the major components and damage of exhaust gas from spray paint process,comprehensively illustrates the purification techniques in waste gas from spraying and analyzes the pre-processing techniques of paint mists as well as the purification techniques in processing VOCs of the organic waste gas. Among them,paint mist pre-processing is mainly divided intro wet processing method and dry processing method. VOCs purification techniques including traditional purification processing techniques,such as adsorption method,absorption method,combustion method and condensation method. The new type purification processing techniques,for example,separation membrane method,photocatalysis method,bioanalysis method,plasma cleaning method and compound purification processing techniques was included. It explains the strengths and weakness of purification mechanism and process procedures,proposing that the compound-type purification processing technique is the development direction in processing exhaust gas from spray paint process in the future. Meanwhile,it points out that the running cost,operating difficulty and stability serve as the urgent problems which shall be solved for the compound-type processing techniques.
