Waste oil and Water Separation System and Pretreatment Apparatus of the Separation System

摘要

The pretreatment apparatus of the present invention includes a waste oil inflow line installed at the inlet side to introduce waste oil into the pretreatment tank, a diaphragm installed in the pretreatment tank, a water separation chamber installed in the pretreatment tank by diaphragm, A waste water discharge line provided on the lower side of the pretreatment tank for discharging water located below the oil water separation chamber and a drain line provided on the bottom of the oil water separation chamber . According to the present invention, the capacity of the waste oil drain tank can be increased by separating the water again from the waste oil introduced into the waste oil drain tank at the inlet side of the waste oil drain tank, without having a dirty drain tank, The waste oil treatment cost can be greatly reduced because the waste oil can be collected.
