1 電除尘设备的类型与特性研究
从字面意义上来说,除尘设备就是用来除去尘埃的,其通过有效控制污染源起到保护环境与大气的效果,在实际应用的过程中,根据设备运行机理的不同,除尘设备可分为用被清除物本身重力除尘,像旋风除尘器、沉降室;用高压静电场力来除尘的高压静电除尘器;用水进行除尘的湿式除尘器;用过滤材料除尘的袋式除尘器、过滤式除尘器等。
1.1 旋风除尘器
这种除尘器的工作机理就是将含有尘埃的气体吸入后在其内部做旋转运动,这样颗粒物就会在离心力的作用下被甩飞到外壁上,从而达到气固分离的净化效果。旋风除尘器的内部构造并不复杂,往往是由铁板焊接而成,其中并未设置运动部件,加工方便、造价低。在使用过程中其耐高温、对高浓度粉尘的处理效果好等优势被彰显的淋漓尽致,给人安全、便利、操作简单的良好印象,其目前已被积极应用于小型锅炉烟尘污染治理中,也可参与到高浓度含尘气体初级净化阶段。……
