袋式除尘器处理风量计算应该注意什么?

袋式除尘器具有设定的处理空气量范围。通常,在设计和使用过程中,灰尘过滤器不能在设定的风量范围之外运行。如果将风量设置得太大,则会阻塞过滤器材料,并且过滤器的压力和压力损失将显着增加,从而导致除尘。
The bag filter has a set range of air handling capacity. Generally, in the process of design and use, the dust filter can not operate outside the set air volume range. If the air volume is set too high, the filter material will be blocked, and the pressure and pressure loss of the filter will increase significantly, resulting in dust removal.
设备的效率下降。
The efficiency of the equipment is reduced.
如果风量小于设计风量,则必须相应增加设备投资和占地面积。
If the air volume is less than the design air volume, the equipment investment and floor area must be increased accordingly.
计算合理的处理风量对集尘器的稳定运行和除尘效果具有重要意义。袋式除尘器处理风量的计算方法袋式除尘器风量的计算方法:处理风量÷过滤器风速过滤面积,一般袋式除尘器风速约为0.8-1.2 / sec;袋式除尘器的截面积*过滤器风速* 60每小时
It is very important to calculate the reasonable treatment air volume for the stable operation and dust removal effect of the dust collector. Calculation method of air volume of bag filter calculation method of air volume of bag filter: treated air volume ÷ The air velocity of the filter is about 0.8-1.2/sec; Sectional area of bag filter * air velocity of filter * 60 per hour
处理风量m3 / h;袋式除尘器的处理空气量是指除尘设备在运行过程中每单位时间可净化的气体量。
Treatment air volume m3 / h; The air handling capacity of bag filter refers to the amount of gas that can be purified per unit time during the operation of dust removal equipment.
布袋除尘器设备入口处的粉尘浓度由粉尘点处的粉尘浓度决定。确定布袋除尘设备的处理空气量时,首先需要查看每个防尘罩下的处理气体量,还要考虑布袋
The dust concentration at the entrance of the bag filter is determined by the dust concentration at the dust point. When determining the air handling capacity of bag type dust removal equipment, it is necessary to check the air handling capacity under each dust cover first, and also consider the bag type dust removal equipment
沸石转轮+催化燃烧
还应考虑集尘设备本身的空气泄漏。
Air leakage of dust collection equipment itself should also be considered.
1:烟气进入袋式除尘器之前的平均速度X过滤器入口的横截面积。应该注意的是,该单位必须统一,通常为每小时每小时立方米。
1: Average velocity of flue gas before entering bag filter x cross-sectional area of filter inlet. It should be noted that the unit must be uniform, usually cubic meters per hour.
2:如果由重建工程部门根据引风机的风量计算得出,则实际风量引风机的X95是布袋除尘器处理的近似空气量。
2: If the Reconstruction Engineering Department calculates the actual air volume according to the air volume of the induced draft fan, the x95 of the actual air volume of the induced draft fan is the approximate air volume of the bag filter.
支撑风扇的风量必须大于布袋除尘器处理的空气量,并且必须考虑风扇的压力损失,因为集尘器,管道,弯头等的压力损失会导致风扇的气压不足,并且空气量实际上无法达到风扇标签上标记的空气量。
The air volume supporting the fan must be greater than the air volume handled by the bag filter, and the pressure loss of the fan must be considered, because the pressure loss of the dust collector, pipe, elbow, etc. will lead to insufficient air pressure of the fan, and the air volume can not reach the air volume marked on the fan label.
