GAS COOLING AND OIL RECOVERY APPARATUS FOR WASTE PLASTICS LIQUEFACTION PLANT

PROBLEM TO BE SOLVED: To provide a gas cooling apparatus of a wastes plastic liquefaction plant which enables a generated hydrocarbon gas to be condensed and recovered as an oil, prevents both a liquid phase line and a gas phase line from being clogged by a sublimate, and enables the sublimate to be...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas cooling apparatus of a wastes plastic liquefaction plant which enables a generated hydrocarbon gas to be condensed and recovered as an oil, prevents both a liquid phase line and a gas phase line from being clogged by a sublimate, and enables the sublimate to be used as a fuel. SOLUTION: This apparatus is equipped with a melting vessel 1 for melting waste plastics containing PVC and PET mixed thereinto; a spray tower 12 for cooling a gas generated in the melting vessel 1 to condense a high-boiling- point fraction to give an oil and for depositing a sublimate from the gas into the oil; and a condenser 13 for cooling the gas having passed through the spray tower 12 to condense a low-boilingpoint fraction to give an oil. The spray tower 12 is equipped with a cooling section 15; a tank section 16; and an oil cooling system 17 for spraying an oil in the tank section 16 through an outer cooler 23 and from a spray 24 installed at the cooling section 15. The low- boiling-point fraction oil condensed in the condenser 13 is recovered as a fuel, and the high-boiling-point fraction oil containing a sublimate and condensed in the spray tower 12 is recovered as a slurried fuel.
