布袋除尘器的阻力由3部分组成：
1、除尘设备本体结构的阻力指气体从除尘器人口，至除尘器出口产生的阻力；
The resistance of the body structure of the dust removal equipment refers to gas exports generated resistance from the the precipitator population to precipitator;
2、滤袋的阻力，指来滤粉尘时滤料的阻力，约50～150Pa；
The resistance of the filter bag, filter media to filter the dust resistance, from about 50 to 150Pa;
3、滤袋表面粉尘层的阻力，粉尘层的阻力约为干净滤布阻力的1～10倍。如果把滤袋及其表面附着的粉尘层的阻力叫做过滤阻力，那么过滤阻力可按下式计算：
此外，过滤阻力还可以利用计算滤尘量的办法查表来求出过滤阻力的近似值。滤尘量可由下式计算：除尘器本体结构阻力随过滤风速的提高而增大，而且各种不同大小和类别的袋式除尘器阻力均不相同，因此，很难用某一表达方式进行计算。一般的过滤风速为0.5～3m/h时，本体阻力大体在50～500Pa之间。但是，在考虑本体结构阻力时，应同时考虑一定的储备量。Bag surface resistance of the dust layer, the resistance of the dust layer is about 1 to 10 times a clean filter cloth resistance. If the filter filter bag attached to the surface of the dust layer resistance is called resistance, filtration resistance can be calculated as follows:
In addition, the filtration resistance can also take advantage of the approach of the amount of calculation precipitator lookup approximation of the filtration resistance is obtained. Calculated the precipitator amount by the following formula: the precipitator body structure resistance with filtration the Winds improve increasing, and a variety of different sizes and classes of baghouse resistance is not the same, therefore, it is difficult to calculate with a certain expression. The general filter Winds 0.5 ~ 3m / h, bulk resistance is substantially between 50 to 500 Pa. However, in considering the body structure resistance, taking into account a certain amount of reserve.
袋式除尘器的种类很多，因此，其选型计算显得特别重要，选型不当，如设备过大，会造成不必要的流费；设备选小会影响生产，难于满足环保要求。 |
