Mobile air filter and air filter cleaning process - for building demolition with safe removal of asbestos residues

摘要

Mobile air filter and filter cleaning process for building demolition with safe removal of asbestos residues. In a demolition site assembly which sucks in and collects dust-laden air for filtration and removal, the novelty is that first the dust-bearing air inlet is closed and the dust filter chamber is exhausted; that the duct filter chamber air outlet is closed to seal and maintain low pressure in the filter chamber; that the low pressure is then relieved by opening and atmospheric air inlet to the filter chamber on the dust inlet side; that the resulting brief reverse pulse of air through the filter transports a portion of the dust through a slot at the base of the filter housing into the dust collection chamber. USE/ADVANTAGE - The arrangement facilitates the removal at intervals of a portion of asbestos dust form a filter used in building demolition works, without human exposure.
