METHOD FOR SEPARATING HEAT-MELTABLE PLASTIC FROM WASTE, METHOD FOR VOLUME REDUCING TREATMENT OF WASTE, AND APPARATUS FOR HEAT TREATMENT OF WASTE

摘要

PROBLEM TO BE SOLVED: To facilitate the recovery of plastics separated from waste by a method in which heat-melted plastics are dropped into water tank installed in the lower part of the lower part chamber of a heating container through a partition and solidified. SOLUTION: A partition plate 5 having a heater is installed in the inside lower part of a heating container 2, an openable/closable treatment material charging port 6 is formed at the upper end, and a generated gas discharging opening 10 is formed in the upper part, molten plastics are charged from the port 6 into the container 2, the port 6 is closed, a pump Pu is operated to actuate a neutralizing agent showering apparatus 17, and a gas hot plate 18 is ignited. Next, the pressure of the container 2 is reduced by actuating a suction blower 12, the heating of the container 2 is started by actuating a heater, after the inside temperature reached 250 deg.C, the heater is stopped, molten slag cooled naturally is dropped into water seal container 9 and solidified.
