<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for treating a mixture gas generated in the apparatus for thermally treating waste material containing plastic by liquefying this with a small amount of water. <P>SOLUTION: The mixture gas 1G including steam, a thermally decomposed gas and an odor component exhausted from a drying apparatus 100 is condensed and liquefied without contact with cooling water W2 in a cooling apparatus 1. An oil content OL is separated from a condensed liquid L1 in an oily water separating tank 4, and a water content placed at a lower layer of the separating tank 4 is extracted and purified by a purifying apparatus 7. Since the condensed liquid L1 is to condense only the mixed gas 1G, the treated amount thereof is substantially small, thus the entire apparatus can be miniaturized. Further, the cooling water W2 is not brought in contact with the mixed gas 1G, thereby basically not to be degraded and enable this to be circulated and flowed over a long period. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
