Description

Stainless steel oil separation tank capable of preventing heavy oil from sinking back

Technical Field

The application relates to the field of oil separation tanks, in particular to a stainless steel oil separation tank capable of preventing heavy oil from sinking back.

Background

The oil separation tank is a wastewater pretreatment structure for removing floatable oil substances in oily wastewater by utilizing the floating effect generated by the density difference of oil drops and water. The structure of the oil separation tank mostly adopts a horizontal flow type, the oily wastewater enters the oil separation tank with a rectangular plane through the water distribution tank, slowly flows along the horizontal direction, floats on the water surface of the oil in the flowing process, and is pushed into the oil collection pipe by the oil collection pipe or the oil scraping machine arranged on the tank surface to flow into the dehydration tank. Heavy oil and other impurities precipitated in the oil separation tank are accumulated in a sludge bucket at the bottom of the tank and enter a sludge pipe through a sludge discharge pipe. The wastewater after oil removal treatment overflows into a drainage channel to be discharged out of the tank, and is subjected to subsequent treatment to remove emulsified oil and other pollutants.

When the horizontal flow type oil separation tank is used, a part of waste water mixed oil product still flows into the oil collecting pipe, so that the oil separation effect is poor, most of oil separation equipment is operated by adopting a passive oil separation method, and oil-containing waste water is required to be naturally separated, so that other impurities such as heavy oil are easily removed, and the oil separation effect is poor due to the fact that the heavy oil is sunk into the oil separation tank.
