锅炉除尘器是锅炉及工业生产中常用的配套设备。它的功能是将锅炉燃料,燃烧排放烟气中的颗粒烟尘加以清除,从而大幅度降低排入大气层中的烟尘量,这是改善环境污染,提高空气质量的重要环保设备。

⑴ 重力沉降作用——含尘气体进入布袋除尘器时,颗粒大、比重大的粉尘,在重力作用下沉降下来,这和沉降室的作用完全相同。

⑵ 筛滤作用——当粉尘的颗粒直径较滤料的纤维间的空隙或滤料上粉尘间的间隙大时,粉尘在气流通过时即被阻留下来,此即称为筛滤作用。当滤料上积存粉尘增多时,这种作用就比较显著起来。  

⑶ 惯性力作用——气流通过滤料时,可绕纤维而过,而较大的粉尘颗粒在惯性力的作用下,仍按原方向运动,遂与滤料相撞而被捕获。    

⑷ 热运动作用——质轻体小的粉尘(1微米以下),随气流运动,非常接近于气流流线,能绕过纤维。但它们在受到作热运动(即布朗运动)的气体分子的碰撞之后,便改变原来的运动方向,这就增加了粉尘与纤维的接触机会,使粉尘能够被捕获。当滤料纤维直径越细,空隙率越小、其捕获率就越高,所以越有利于除尘。
