本实用新型的工作原理：可以将含有烟尘的气体通过烟气进口3送入到烟气进管13内，使得含有烟尘的气流进入到沉降箱1内，进入到沉降箱1内的烟 气经过多个沉降腔14并反复与第一分隔板15和第二分隔板16碰撞，连续的碰撞形式使得烟尘更加容易沉降，提高了沉降的效果，且通过在第一分隔板15和第二分隔板16表面均设有合成蜡层19，可以避免灰尘堆积在第一分隔板15和第二分隔板16上，保证沉降效果好，同时，余热回收机构，可以将烟气进管13上的余热进行回收，可以利用循环水泵7将循环水箱5内的水抽出兵送入到上环形储水座11内，然后进入到多组导热水管10内进行余热回收，最后通过下环形储水座9和回水管8回收到循环水箱5内，具有一定的环保效果，降尘后的气流通过锥形进烟口17进入到烟气排管4内，锥形进烟口17增加气流的压力，并吹向震落组件上的叶片21进行转动，叶片21转动的同时通过橡胶拍打块22与过滤网23上的橡胶受力条12接触，从而对过滤网23进行拍打震落，使得过滤网23上粘附的灰尘掉落，避免过滤网23堵塞，可以进行连续过滤工作，同时活性炭过滤组件18可以对排出的气体进行过滤净化，增加排出气流的洁净度，便于使用。
