袋式除塵器具有設定的處理空氣量范圍。通常，在設計和使用過程中，灰塵過濾器不能在設定的風量范圍之外運行。如果將風量設置得太大，則會阻塞過濾器材料，并且過濾器的壓力和壓力損失將顯著增加，從而導致除塵。
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.
設備的效率下降。
The efficiency of the equipment is reduced.
如果風量小于設計風量，則必須相應增加設備投資和占地面積。
If the air volume is less than the design air volume, the equipment investment and floor area must be increased accordingly.
計算合理的處理風量對集塵器的穩(wěn)定運行和除塵效果具有重要意義。袋式除塵器處理風量的計算方法袋式除塵器風量的計算方法：處理風量÷過濾器風速過濾面積，一般袋式除塵器風速約為0.8-1.2 / sec；袋式除塵器的截面積*過濾器風速* 60每小時
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
處理風量m3 / h;袋式除塵器的處理空氣量是指除塵設備在運行過程中每單位時間可凈化的氣體量。
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.
布袋除塵器設備入口處的粉塵濃度由粉塵點處的粉塵濃度決定。確定布袋除塵設備的處理空氣量時，首先需要查看每個防塵罩下的處理氣體量，還要考慮布袋
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

還應考慮集塵設備本身的空氣泄漏。
Air leakage of dust collection equipment itself should also be considered.
1：煙氣進入袋式除塵器之前的平均速度X過濾器入口的橫截面積。應該注意的是，該單位必須統(tǒng)一，通常為每小時每小時立方米。
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：如果由重建工程部門根據(jù)引風機的風量計算得出，則實際風量引風機的X95是布袋除塵器處理的近似空氣量。
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.
支撐風扇的風量必須大于布袋除塵器處理的空氣量，并且必須考慮風扇的壓力損失，因為集塵器，管道，彎頭等的壓力損失會導致風扇的氣壓不足，并且空氣量實際上無法達到風扇標簽上標記的空氣量。
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.
