Introduction to the principle of filter dust removal equipme
Filter type is similar to the mask, dust removal equipment dust removal mechanism is through filtering material to mechanical block section of fly ash particles in the air, the other received first fly ash particles in the filter material surface formed a thick layer of the stability of the ash layer, known as the filter cake or feel secure on the bed, it was a very good filtering effect again. Filter element can be made of cotton fiber, glass fiber or all kinds of chemical fiber textile (or acupuncture) as filter material, and then sewn into a vertical suspension of filter bag, different occasions to choose different filter material. The dust collected on the filter bag can deform the cloth bag by means of periodic mechanical dithering, filtered flue gas, or compressed air.
过滤式除尘设备除尘机理类似于口罩，是通过过滤材料对空气中的飞灰颗粒进行机械拦 截来实现的，另先收到的飞灰颗粒在滤料表面形成了一层粘稠的稳定的灰层，称为滤饼或虑床，它又起了很好的过滤作用。过滤元件可以由棉毛纤维、玻璃纤维或各种化学纤维经过纺织（或针刺）成滤料，再缝制成垂直悬挂的滤袋，不同场合要选用不同的滤料。在滤袋上收集到的粉尘通过周期性的机械抖动、过滤后的烟气反吹或压缩空气的脉冲反吹等途径使布袋变形而将灰清除。
