Energy-saving universal oil-water separation device

Abstract

The invention discloses an energy-saving universal oil-water separation device which comprises an oil-water mixed liquid injection unit, a light oil / water separation unit, a heavy oil / water separation unit, a drainage unit and a fixing unit, the fixing unit is used for fixing the oil-water separation device; the oil-water mixed liquid injection unit comprises an infusion pump and an injection pipe which are used for realizing continuous injection of oil-water mixed liquid; the light oil / water separation unit comprises a filtering module based on a super-hydrophobic-super-oleophylic metal net and a light oil discharge channel; the drainage unit comprises a partition plate used for preventing oil from being brought out of the drainage unit, an automatic drainage module and an overflow valve. The heavy oil / water separation unit comprises a super-hydrophobic-super-oleophylic filter screen for filtering a heavy oil / water mixed solution and a fixing module of the super-hydrophobic-super-oleophylic filter screen. When a light oil (or heavy oil) / water mixed solution or an oil-water mixed solution of three components of heavy oil / water / light oil is continuously injected into the separation device, oil-water separation can be automatically completed in an energy-saving manner; the device is simple, and is easy to operate and implement.

Description

technical field

[0001] The invention belongs to the technical field of oil-water separation, and in particular relates to an energy-saving general-purpose oil-water separation device. Background technique

[0002] With the acceleration of industrialization, environmental pollution has become increasingly serious; among them, the continuous discharge of industrial oily wastewater and frequent oil spill accidents have caused serious damage to water resources and ecological environment. Although traditional oil-water separation technologies such as gravity sedimentation method, centrifugal method, adsorption method, etc., can achieve the purpose of oil-water separation, there are common problems such as low separation efficiency and insufficient separation purity. Therefore, how to achieve effective oil-water separation has received great attention from academia and industry.
