Combined electric ash collector

This is a smoke ash purifying device in industry. It is not only a co-axle combination of several tube electric ash collection, but also a series combination of single area and two area electric ash collector. It also combines the electric field and rotary wind collection, it itself may be as an element to be combined parallelly or seriesly. The upper ends of its inner and outer tubes are isolated by collector cylinder, and the low ends are penetrable through ash bucket. Smoke tangentially enters the inner tube electric field from the collector cylinder to perform the first ash collection by electric rotary wind and then, perform the second time collection in the ash bucket by subsiding and electricity, the outer tube performs two-area electric ash collection, the ash is recharged in the ionization region and then, in the homogeneous stronge electric field of the collection area the smoke purification is completed, the purified smoke is then exhausted from the collector cylinder.
