Experimental comparison between dry and wet processes for paint mist separation
[Introduction]As one of the key pollutants generated during painting operations,the effectiveness of paint mist treatment is pivotal to the success of treating other pollutants. There are few reports on comparative studies under the same operating conditions for the common paint mist treatment methods i.e. dry and wet processes.[Method]The treatment of paint mist generated in the spray painting workshop was studied experimentally by a dry process combining ball filtration and glass fiber filtration and a wet process using a hydrocyclone,respectively.[Result]The average removal efficiency of paint mist was 95％ for the dry process and 98％ for the wet process. Wet process demonstrated a lower emission concentration and more stable performance as compared to the dry process. However,both methods exhibited the issue of paint mist adhering to the inner walls of the treatment equipment.[Conclusion]In engineering applications,the selection of paint mist treatment process should be tailored to the specific circumstances of the project.
