<p>PURPOSE:To continuously obtain a fuel oil in high yield, by conducting thermal decomposition of a resin waste in the absence of air, cooling the resultant carbonization gas and separating into a liquid product and a gas. CONSTITUTION:A resin waste is crushed into chips of 10-15mm by a crusher 1, and fed through a cyclone and a hopper 3 in the absence of air into a carbonization oven 5, where the waste is heated by a burner 6. The carbonization gas generated when the temp. in the oven is below 200 deg.C is fed through a distilling device 12 into a cooler 13 where cooling is performed. On the other hand, the carbonization gas generated when the temp. in the oven is 200 deg.C or above is directly fed into the cooler 13 where cooling is performed. The cooled gas mixture is collected through the oil of a condenser 14 in a tank 15. The content of the tank is purified by passing through a dust separator 16, an oil separator 17 and a centrifuge 18, thereby obtaining a fuel oil. The has having not condensed in the condenser 14 is fed through the tank 14 to a gas cushion 21 where the gas is brought into contact with a contact material and converted to an oil, while promoting dew condensation. The resultant oil is washed with an alkali in a scrubber 22 and then with water in a washer 23. The thus obtd. oil is fed to the burner 6 for use as a fuel for the oven 5.</p> |
