袋式除尘器来说,使用温度与除尘效率关系并不明显,这一点不同于电除尘,对电除尘器来说,温度的变化会影响到粉尘的比电阻等影响除尘效率。
 
For bag filter, the relationship between the service temperature and the efficiency of dust removal is not obvious, which is different from the electrostatic precipitator. For the electrostatic precipitator, the change of temperature will affect the specific resistance of dust and so on.
 
入口含尘浓度(g/m³):即入口粉尘浓度,这是由扬尘点的工艺所决定的,在设计或选择袋式除尘器时,它是仅次于处理风量的又一个重要因素。
 
The entrance of dust concentration (g/m: entrance dust concentration fand), which is decided by the process of dust, in the design or selection of bag type dust collector, it is also an important factor behind the air quantity.

以g/m3或g/Nm3来表示。对于袋式除尘器来说,入口含尘浓度将直接影响下列因素:压力损失和清灰周期。入口浓度增大,同一过滤面积上积灰速度快,压力损失随之增加,结果是不得不增加清灰次数。
 
It is represented by g/m3 or g/Nm3. For the bag type dust collector, the dust concentration at the entrance will directly affect the following factors: the pressure loss and the ash clearing period. With the increase of the inlet concentration, the speed of ash accumulation on the same filter area is fast, and the pressure loss increases. The result is that the number of ash clearing times has to be increased.
 
滤袋和箱体的磨损。在粉尘具有强磨蚀性的情况下,其磨损量可以认为与含尘浓度成正比。预收尘有无必要。预收尘就是在袋式除尘器入口处前再增加一级除尘设备,也称前级除尘。排灰装置的排灰能力。
 
The wear of the filter bag and the box. In the case of strong abrasiveness, the amount of wear and tear can be considered to be proportional to the dust concentration. There is no need to pre collecting. The advance is in the dust bag dust collector at the entrance before the increased level of dust removal equipment, also known as the dust before. Ash discharging capacity of ash discharging device.
