る。The oil content A discharged into the second oil / water separation tank 8
Is mixed with water B, the oil A and the water B are further separated. Since the lower side of the second oil / water separation tank 8 communicates with the storage tank main body 12, the water B in the second oil / water separation tank 8 flows into the storage tank main body 12, and the oil component A is the lower limit A 1 of the layer. The storage tank body 1 has a side through the oil discharge hole 9A of the partition plate 9.
2 flows into. The reason why the oil component A is discharged from the second oil / water separation tank 8 to the storage tank main body 12 through the oil discharge hole 9A is to prevent dust from being mixed. Further, in the above-described process of separating the oil component A and the moisture B, the washing water is sprayed from the washing water spray device 10 onto the oil surface. As a result, the dust that has increased in specific gravity due to the attachment of water droplets to the dust floating on the oil surface settles down in the moisture B layer, so that the dust can be removed from the oil component A.

On the other hand, the water B in the storage tank main body 12 is discharged by the drain pipe 14 to the same wastewater treatment facility as the sewage drain pipe 7. The oil content A in the oil amount adjusting tank 16 is discharged to the residual moisture removing device 18 by operating the on-off valve 17, and the residual moisture is evaporated by heating the oil component A by the steam heater 21 in the residual moisture removing device 18. Oil A from which water B has been completely removed
Is discharged to the oil cooling tank 24 through the communication pipe 25 and cooled. Thus, the high-purity oil component A from which dust and moisture B have been removed can be recovered. Note that the oil cooling tank 24 may be used as a recovered oil storage tank, but another recovered oil storage tank may be installed.
