XDP Low-resistance dust collector

Adopt diameter-variable log spiral volute barrel divided into inside and external revolving barrels, the flow is distributed by centre joint, then use the plate to block the dust and base plate to remove the forced vortex flow for reducing resistance loss and separating the dust for entering into taper hopper, lastly, discharged from dust-exhausting port.  There is no driving part and guide impeller in dust collector, so the maintenance is less without blockage, even happen to special condition and cause dust-accumulation in barrel, just clean it from inspecting holes.  Divided into vertical type(II type)、horizontal(III type), thus it is more flexible and convenient to arrange the pipe connection.Simple structure、small floor space、lighter weight、less steel consumption and easy to discharge ash.Due to lower resistance, suitable for normal natural induced draft boiler or mechanical induced draft boiler, for the boiler and manufacturing equipments with high initial dust concentration needing secondary series connected dust removal device for reaching state standard of effluent discharge, if use the dust collector as the first stage purification, the system resistance will be reduced as well as power loss, generally, there is no need to use high pressure positive blower, and two series induced drafts more.With diameter-variable volute conforming to the moving track of grain, reduce the bouncing phenomenon of large grain, so there is less abrasion with long service life.
