多层喷雾洗涤塔对粉尘颗粒的脱除特性
Performance of dust removal in a multi-layer spray column scrubber
摘要
Abstract
An experimental device was built up to study the dust removal characteristics in multi-layer spray column scrubber.The operating parameters which influence dust removal efficiency were analyzed,such as volume ratio of liquid to gas,average velocity of gas in column,inlet dust loading and spray pressure.The results showed that the spray layer have most significant influence to dust removal.The efficiency of three-layer column scrubber increased by more than 15％ compared with the traditional washing tower,and inlet dust loading have little impact on it.Increasing spray pressure can enhance the efficiency of dust removal obviously.When spray pressure is 0.5-0.6MPa,the dust removal efficiency will be stable.Under the same operating parameters,reducing the average velocity of gas in scrubber will help to improve dust removal efficiency.For the three-layer column scrubber,the best average velocity of gas is 0.6-0.8m/s.In this experiment,dust removal efficiency can reach 98.3％ in three-layer spray column scrubber,when spray pressure is 0.6MPa,the average velocity of gas in column is 0.6m/s,and volume ratio of liquid to gas is 5.27.关键词
