Title:
APPARATUS AND METHOD FOR CONVERTING HAZARDOUS WASTE CONTAINING UNREACTED RESIN AND SOLVENTS INTO DISPOSABLE NON-HAZARDOUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/043642
Kind Code:
A3
Abstract:
A hazardous waste mixture including incompletely polymerized resin and volatile solvents from production of artificial stone and similar products is converted into non-hazardous material by passing it through a horizontal reactor, where it is heated in a first zone to just below its polymerization temperature, driving off any solvents with low boiling points, and then heated in a second zone above its polymerization temperature, thereby fully polymerizing the waste while driving off any solvents with high boiling points. An exit dam maintains some waste in the reactor while excess waste flows over the dam and out of the reactor. An airflow can be used to carry away the solvents. Chopping blades can break up the waste into small granules. Agitating paddles can mix the waste with air, dislodge waste from reactor walls, and direct waste to the blades. Compounds needed for complete polymerization can be added through a feeder port.
