Abstract

The utility model discloses a transformer accident oil pool oil-water separation device which comprises a floating box, a plurality of floating barrels are arranged on the periphery of the floating box, the floating box floats in an oil pool through the floating barrels, a water collecting bin is arranged in the inner space of the floating box, and a floating oil collecting box and an annular oil collecting box arranged around the floating oil collecting box are arranged at the inner top of the water collecting bin. A floating oil collecting inlet is formed in the top of the floating oil collecting box, and the box bottom of the floating oil collecting box is open and is closed through an oil-water separating film; the oil well pump is arranged at the top end of the floating box and is used for pumping an oil-water mixture in the oil pool into the floating oil collecting box through the floating oil collecting inlet; the motor stirring mechanism is mounted at the top end of the floating box and is used for stirring an oil-water mixture in the floating oil collecting box; and the oil collecting pump is arranged at the top end of the floating box and used for pumping floating oil in the floating oil collecting box into the annular oil collecting box through an oil collecting pipe. According to the device, efficient oil-water separation is completed by adopting gravity pre-separation, oil film enhanced separation and motor driving acceleration.
