METHOD OF AND APPARATUS FOR REMOVING OIL FROM A WASTE OBJECT

摘要

A WASTE OBJECT (W) CONTAINING OIL HAS A FIRST OPENING (8) FORMED THEREIN AT AN UPPER PORTION THEREOF AND A SECOND OPENING (10) POSITIONED BELOW THE FIRST OPENING (8). THE FIRST AND SECOND OPENINGS (8, 10) ARE CONNECTED TO A RECOVERY TANK (18). HOT WATER OF A PREDETERMINED TEMPERATURE IS HELD IN THE RECOVERY TANK (18) AND IS CAUSED TO ACCUMULATE INSIDE THE WASTE OBJECT (W) VIA THE SECOND OPENING (10). OIL THAT HAS FLOATED UPWARDS IS RECOVERED IN THE RECOVERY TANK (18) VIA THE FIRST OPENING (8).
