Imported dust concentration:
That is the concentration of imported dust, which is determined by the process of raising the dust point, is an important factor next to the processing volume when designing or selecting a bag filter. Expressed in g/m3 or g/Nm3. For bag filter, the imported dust concentration will directly affect the following factors: (1) Pressure loss and cleaning cycle. As the import concentration increases, the ash accumulation speed on the unified filter area increases and the pressure loss increases. As a result, the number of cleaning operations has to be increased. (2) Wear of filter bags and boxes. In the case of dust with strong abrasiveness, the amount of wear can be thought of as being proportional to the dust concentration. (3) It is not necessary to collect dust in advance. Pre-collection of dust is to add an additional level of dust removal equipment before the dust collector inlet, also known as pre-dust. (4) The ash discharging capacity of the ash discharging device. The ash discharging capacity of the ash discharging device shall be based on the ability to discharge all received dust, and the amount of dust is the imported dust concentration times the treated air volume.
