Abstract
The invention provides a method for removing the sprayed-on asbestos, the method comprising the steps of: (1) removing the asbestos-containing materials sprayed, and sucking up the asbestos-containing materials by a suction hood before they drop onto the floor or the ground; (2) conveying the absorbed asbestos-containing air by transport means to a receiver tank containing a liquid wherein the air is bubbled, and sucking up the bubbled air by a suction blower; and (3) transferring the asbestos-containing liquid in the receiver tank to a dehydrator by a discharge pump to separate the asbestos-containing solids from the liquid, and delivering the separated liquid directly to the receiver tank or to the transport means by a return pump for returning the liquid to the receiver tank, and an apparatus therefor.
