A continuous oil-water separation device

Abstract

The invention discloses a continuous oil-water separation device. The continuous oil-water separation device comprises an oil drawing unit and a separation unit, wherein the oil drawing unit is communicated with the separation unit through a pipeline with a pump; the separation unit comprises a separation tank, and a liquid inlet, a buffer area, an oil-water separation area and a return area are arranged in the separation tank. When the oil-water separation device works, the oil drawing unit is fixed on the liquid surface of waste liquid containing oil, floating oil containing a small amount of solution enters the oil drawing unit and is conveyed into the separation tank, pure oil after treatment is separated and collected to an oil tank, and the separated waste liquid is returned into the original tank liquid and can be used continuously. The continuous oil-water separation device has the advantages that the device is simple and compact in structure, low in cost, energy-saving, environmentally friendly, capable of performing continuous oil removing on various water containing oil, simple in process flow, and high in purity of recycled oil; in addition, the device does not need any electric control, can stably operate for a long time, and is less prone to damage and widely applicable to fields such as environment protection, chemical industry, medicine industry, metal smelting and machinery.

Description

technical field [0001] The invention relates to a continuous oil-water separation device, which belongs to the field of machinery. Background technique [0002] Oil-water separation in wastewater treatment is an important separation process, which is widely used in the production and life processes of food, life and industry, such as the recovery and separation of oil spilled on the water surface, the oil-water separation of crude oil in the modern oil exploitation process, and the filtration of fuel oil for engines. And recovery of industrial lubricants. At present, common oil-water separators mainly use the difference in oil-water density to separate oil-water through gravity, centrifugal force, etc., and have defects such as high energy consumption, low processing capacity, inconvenient operation, or incomplete separation. Therefore, it is of great significance to research on oil-water separators that are energy-saving, environmentally friendly, high-efficiency, low-cost...

AI Technical Summary

Problems solved by technology

However, when the device is working, all the sewage water body needs to pass through to separate the slick oil. It is not suitable for treating the sewage water body produced by large-scale industrial production or the water body with a large water area, and consumes a lot of energy. At the same time , the slick oil obtained after treatment by this device still contains a lot of water, and it needs to be further treated before it can be recycled.

In addition, if the device is used to deal with highly corrosive chemical reaction liquids containing slick oil, etc., the whole device will be easily corroded, thus shortening its service life.
