DMC type pulse bag roof collector

DMC type pulse bag roof collector
  DMC type pulse bag roof ash collector is proper to be arranged on the top of various powder materials storehouse to capture different fine dry non-fiber dusts.

Main technical parameters:
  In main technical parameters of DMC type pulse bag roof collector the ash density at the inlet should be noticed during type selection. In technical performance the air flow through filter-bag (i.e. filtering air speed) is in reverse proportion to the ash density contained in air, therefore, the ash accumulating capability of the filter-bag (i.e. the maximal permissive ash accumulating quantity in unit area of the filter-bag during two ash removals) must also be satisfied when filtering area is determined, in general the ash accumulating capability is not over 400g/m2 and can be calculated based on the equation as follows:
  Ash accumulating capability=ash density contained in air at the inlet×filtering air speed×interval between two ash removals. If the calculated result exceeds the ash accumulating capability, the filtering air speed should be adjusted and the filtering area be added.
