除尘设备是褐煤烘干机使用中少不了的，一般来说，厂家在烘干机出厂时都会配有相应的除尘器工用户配套选用。当然用户也可自行购置其他类型的除尘设备进行安装使用。但是总的原则就是所选设备的匹配性和除尘效果要理想。针对用户反应的除尘设备使用中达不到预期效果，一布袋除尘器为例，正科机械总结了一下几点原因。
   1、由于原料的含水量经常超标，有时达到 20％。经煤泥烘干机烘干后，每小时大约有1吨的水份蒸发进入烟气，烟气的湿度增加，增大了褐煤烘干机烟气在布袋除尘器内部的结露。因而除尘效果慢慢变得不理想。    
2、配套风机的选型存在误差。煤泥烘干机配备的风机由于除尘器结露导致布袋阻力增大，烟尘不能被正常抽滤。
   3、烟气温度过高。由于烟气温度过高导致布袋除尘器滤袋被烧结、焦化。有的厂家为了控制进入除尘器的烟气温度，在烟气管道上开孔，让外界冷风和烟气混合降低烟气温度以达到保护滤袋的目的。但是，由于烟气结露、尘粒吸潮，使烟气不能正常通过除尘器， 即褐煤烘干机的布袋除尘器处于失灵状态。  
 4、冷风反吹清灰存在的问题。由于使用外界冷风反吹清灰，滤袋中的烟气突然与大量冷空气混合，烟气温度急剧下降，同一湿度条件下降低温度，更增加了烟气在布袋难以除尘的情况。更多褐煤烘干机价格欢迎访问我们的网站查看。

Several causes lignite dryer dust removal equipment effect is not ideal Dust removal equipment is little not in lignite dryer use, in general, manufacturers in the dryer factory workers will be equipped with corresponding filter when customers choose. Of course the user can also buy other types of dust removal equipment used for installation. But there is the general principle of the selected equipment matching and dust removal effect is ideal. In view of the user response dust removal equipment using zhong da is less than the desired effect, a cloth bag dust collector, for example, are mechanical summarized the reason about. 1, because the water content of raw material is often exceeds bid, sometimes up to 20%. After coal slime dryer drying, about 1 ton per hour moisture to evaporate into the flue gas, flue gas humidity increase, increasing the lignite dryer flue gas condensation inside the bag dust collector. So not ideal dedusting effect. 2, form a complete set of fan selection error exists. Coal slime dryer equipped with fan due to dust catcher condensation bag
