The oil vapor distilled from the top of the deoiling tower exchanges heat with the raw materials, and then flows into the deoiling receiving tank automatically for oil-water separation after being cooled by a condensing cooler at the top of the deoiling tower, the separated water enters the drainage tank, and the oil enters the distillate receiving tank.
