A gas-assisted oil film dispersion extraction device applied to industrial wastewater and its method

Abstract

The invention discloses an air-assisted oil film dispersion extraction device applied to industrial wastewater, comprising a pressurization unit, a separation pressurization device, a fixing frame, a three-phase centrifuge, a support frame, a waste water tank and a base; the pressurization unit includes The first booster pump, the second feed port, the first feed port and the pressurization chamber, the separation pressurization device includes a fixed foot, a third feed port, an extraction unit, an extraction membrane partition, a first oil outlet The three-phase centrifuge includes a centrifugal motor, a centrifugal chamber, a liquid inlet, a slag outlet, a second oil outlet and a second water outlet, which can solve the problem that existing industrial wastewater treatment devices cannot effectively separate The problem of water and grease affecting the treatment of industrial wastewater can also solve the problem of incomplete separation of water and grease in industrial wastewater treatment devices, which increases the cost of industrial wastewater treatment, and can also solve the problem that existing industrial wastewater treatment devices do not treat grease Problems that affect the normal operation of oil purification treatment.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment devices, in particular to an air-assisted oil film dispersion extraction device and a method thereof applied to industrial wastewater. Background technique [0002] At present, the industrial wastewater treatment devices on the market have poor separation effect on the waste water and the oil in the wastewater, which makes it difficult to affect the next step of industrial wastewater treatment. In addition, most industrial wastewater treatment devices, due to their own conditions and process limitations, make industrial wastewater The treatment device does not completely separate water and grease, so multiple treatments are required to separate water and grease, which increases the treatment cost of industrial wastewater. Industrial wastewater treatment devices on the market do not treat the initially separated grease, thus There are cases where oil purification treatment is difficul...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a gas-assisted oil film dispersion extraction device and its method applied to industrial wastewater, which can solve the problem that the existing industrial wastewater treatment devices cannot effectively separate water and grease, thereby affecting the treatment of industrial wastewater, and can also solve the problem of industrial wastewater The treatment device does not completely separate water and oil, which increases the cost of industrial wastewater treatment. At the same time, it can solve the problem that the existing industrial wastewater treatment device does not process oil and affects the normal process of oil purification.
