袋式真空吸尘器与水过滤式真空吸尘器道路尘土收集方法对比研究

摘要

针对袋式真空吸尘器采集道路尘土存在的问题,提出了水过滤式真空吸尘器采集道路尘土的方法.试验表明,该方法可以较完整地收集道路上各种粒径的尘土,细颗粒物收集率超过85％,全部尘土收集率达98％以上.对采集到的道路尘土样品进行粒径分析表明,道路尘土中含有约1.6％的细颗粒物成分.%In order to solve the problem of collecting road dust with bag vacuum cleaner,water filter vacuum collector was proposed.The tests showed that this method can collect all kinds of dust particles on the road,the collection rate of fine particles is over 85％,and the overall dust collection rate is above 98％.The particle size analysis of the collected road dust samples showed that the road dust contains about 1.6％ of fine particles.
