The relationship between the inlet concentration and the selection of the filter cartridge dust collector

The theoretical limit value of the inlet concentration that the cartridge filter can accept is 15g/m³. Generally, we refer to the concentration lower than 5g/m³ as the relatively low inlet concentration. At this time, a horizontally installed filter cartridge dust collector can be used, which is convenient for disassembly, assembly and maintenance. The biggest disadvantage of this method is that the cleaning effect is not good, and the cost is slightly higher. The filtering area of its single filter cartridge needs to be smaller to ensure its back-blowing effect. For those with low dust concentration, generally we use a filter cartridge of 325mm or 350mm, a height of 600mm or 660mm, and a single filter area of about 10-12m² or 20m². For this low concentration, we can use pulse valve blowing. However, once the dust concentration is higher than 5g/m³, in this case, only a one-dozen-one injection method can be adopted. This injection method can ensure that its filter cartridge can be operated stably for a long time without clogging, and ensure the uninterrupted operation of the filter cartridge dust collector at the same time. If the dust concentration is higher than 15g/m³, in this case, for the filter cartridge dust collector, theoretically it is necessary to install a secondary dust removal, which can ensure its filtering effect.
