| Abstract: | "Environmental contamination issues have steadily surfaced with the rapid development of the cooking industry. In this paper, the front end of the cooking fume exhaust was filtered by the filter material, and then, the ultraviolet photolysis technology was used for in-depth treatment. The filter material filtration performance of glass fiber, molecular sieve, and composite filter material was studied by the filter efficiency, filter resistance, and quality factor three filter performance indexes. The results show that the filter wind speed has a significant influence on the filter material fume filtration characteristics. The filtration efficiency of the pre-filter material changes the least with the increase of the wind speed when the wind speed is 18 m.s(-1) and the filter material tilt Angle is 60 degrees ; meanwhile, the pressure drop of the two kinds of filter material is reduced, and the quality factor is improved. Under the optimal wind speed and angle, the composite filter material of glass fiber and molecular sieve combined with UV photolysis technology was used to study the treatment of formaldehyde and acrolein, which are two volatile organic pollutants with high content in cooking fume, and the mineralization mechanism of formaldehyde and acrolein under UV light was analyzed. The results showed that the removal rates of formaldehyde and acrolein could reach 99.84% and 99.75%, respectively" |
