Abstract

PURPOSE:To recover the chloric acid of high concentration or the like by carrying the gas generated by heat decomposition during heat treatment of the waste such as vinyl chloride from the heat composition chamber which was previously purged with the gas by combustion of hydrocarbon fuel. CONSTITUTION:Before the heat treatment, the heat decomposition chamber 2 is heated by a heating furnace 2a and fed with the gas generated by a combustion-gas product generator 5 to make an inactive atmosphere by purging the active atmosphere and then, a material to be treated of a vinyl chloride and a synthetic thermoplastic waste is charged from an inlet 3. The material is decomposed in the chamber and a produced gas containing hydrochlorine, hydrogen, methane and the like is introduced into a condensing column 9 by a combustion product gas fed from the generator 5 to separate the hydrochlorine and organic substances above about 60 deg.C of the boiling point. The hydrochlorine or the like thus obtained is gravity-separated into chloric acid and oil, and after the organic substance as malodorous component is removed with activated charcoal adsorption column, a chloric acid about 30-35% in concentration can be obtained.
