布袋除尘器技术应用及过滤原理分析

发布日期: 2018-05-14 作者: 新科环保 点击:

布袋除尘器在运行过程中灰斗处有大量粉尘缓慢下落,而逆流而上的漏风气流造成下落粉尘的二次飞扬,多次循环,排灰口处漏风情况可使除尘器的含尘浓度大大高于进气的含尘浓度,如果不堵住除尘器排灰口的漏风处,会因为恶化除尘器的工作条件而影响布袋除尘器的除尘效率。

分析布袋除尘器滤尘工作原理一般会用到关于惯性撞击、重力、拦截以及静电力、扩散等粉尘粒子的物力沉降原理。通常来说,布袋除尘器在捕集上粉尘粒子的沉降也就是分离过滤,并不是只有一种过滤机理起作用,而是有很多的过滤机理在起作用。
专家依据工业粉尘不同的粒径在流体运动中体现的不同的力学特点,过滤原理会涉及以下几个内容:
