Abstract

The invention discloses a waste emulsified oil low-temperature separation system, which comprises a stock solution input pipe, a heat exchanger, an evaporator, an oil / water separating device, a condenser and a smell removal device; the evaporator comprises a heating chamber, an evaporating chamber and a steam conveyer pipe; a vapor compressor is arranged on the steam conveyer pipe; the stock solution input pipe passes through the heat exchanger and is connected to the heating chamber of the evaporator; a distilled water conveyer pipe passes through the heat exchanger and is connected to the oil / water separating device; a distilled water output tube and an oil exit pipe are arranged on the oil / water separating device; and the oil exit pipe is connected to the condenser and the smell removal device in order. Based on a purely physical mode, gasification separation can be carried out according to boiling point difference of different liquid, distilled water and a concentrate are separated through pure distillation, usually, distilled water can be taken as industrial water for recycling, the concentrate can be recovered and reused according to different source, zero waste water discharge in industrial enterprises can be realized, the waste emulsified oil low-temperature separation system is convenient for systematization and equipment, so that land occupation area is greatly reduced by comparing with that in a traditional method.

Description

technical field [0001] The invention relates to a low-temperature separation system for waste emulsified oil. Background technique [0002] Oily wastewater is a kind of industrial wastewater, and it is a large discharge of industrial wastewater. Oily wastewater mainly comes from petroleum, petrochemical, steel, coking, gas generation stations, mechanical processing and other industrial sectors, including oilfield wastewater, wastewater from refineries and petrochemical plants, ballast water, tank washing water, engine room water of tankers, Oil tank (tank) car cleaning water, etc. Oily wastewater is the main source of environmental oil pollution, especially marine oil pollution (such as oil pollution). Wastewater from gas plants and coking plants contains coal tar, and waste water from tanneries and food processing plants contains animal and vegetable oils. These also belong to oily wastewater, but the proportion is not large. [0003] Usually oily wastewater treatment te...
