OPERATING EFFICIENCY AND HYDRODYNAMICS OF CONICAL DUST COLLECTORS WITH SWIRLING COUNTERFLOWS

摘要

The operating principle of dust collectors with swirling counterflows (SC) is examined. An efficiency of 80-85% is achieved during tests of an SC vessel under industrial conditions. The velocity fields of the gas flow in different sections are analyzed over the height of the SC vessel. The influence exerted by the taper of the effective zone of the SC vessel on the dust-entrapment efficiency is investigated. Results are presented for comparative hydrodytxamic tests of cylindrical and conical SC dust collectors.
