Abstract: With the rapid development of catering industry in China,a large number of cooking fumes containing harmful gases and carcinogens have been emitted directly into the air,which need to be treated urgently. However,the purification efficiency of traditional methods is low and cannot meet the emission standard. To solve this problem,a composite cooking fume purifier was developed using technologies of centrifuge,filtration,corona discharge and photolysis. The purification efficiency,discharge current,and ozone concentration were studied. The results showed that when using the technologies of centrifuge,filtration and corona discharge,the purification efficiency was the most stable and kept about 95% with the increase of working hours. When there were filter layers,the discharge current in the electrostatic section decreased slowly over time,and it was more slowly at the negative corona discharge at the same voltage. When there was electrostatic section,the ozone concentration of cooking fume purifier was the highest,and it decreased most slowly after adding filter layers. Overall,the filtration technology could effectively improve the purification efficiency,slow down the decline of discharge current and ozone concentration.

Key words: cooking fume composite purifier, purification efficiency, discharge current, ozone concentration

摘要: 随着我国餐饮业的迅速发展,大量含有有害气体和致癌物质的烹调油烟直接排放到空中,亟需治理,而传统方法净化效率不高,无法满足排放标准。为了解决这一问题,本文利用离心技术、过滤技术、电晕放电技术和光解技术组合成复合式油烟净化器,并对其净化效率、放电电流和臭氧浓度进行了相关研究。研究结果表明,随着工作时间的增加,离心技术、过滤技术和电晕放电技术组合的净化效率最为平稳,保持在95%左右;有过滤层时,静电段放电电流随工作时间的增加衰减的较慢,且相同电压下,负电晕放电时放电电流随工作时间衰减的更慢;有静电段时,油烟净化器的臭氧浓度最高,且添加过滤层技术后臭氧量减少趋势最慢。总体而言,过滤技术有效地提高了净化效率,减小了放电电流和臭氧浓度的衰减。
