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.
