Embodiment 1

[0037] Use polypropylene filter as the first layer of separation material with a separation pore size of 70-100 μm, polyester non-woven fabric as the second layer of separation material with a separation pore size of 5-10 μm, and polypropylene microporous membrane as the third layer The separation material has a separation pore size of 0.1-0.5 μm, and the polysulfone ultrafiltration membrane is used as the fourth separation material with a separation pore size of 0.01-0.05 μm. Each layer of separation material is separated by a polyester grid with a thickness of 5 mm, and the grid is encapsulated with epoxy resin, and PVC pipelines are embedded in the epoxy resin, and the pipelines of each layer are connected to the four-channel valve On, the cleaning sequence is controlled by adjusting the valve. The whole separation device is a flat plate frame type.

[0038] The oil content in the influent water is 1000mg / L, the oil removal operation is carried out at 0.2MPa, and the flux ...

Embodiment 2

[0042] Use polypropylene filter as the first layer of separation material with a separation pore size of 60-80 μm, use polypropylene non-woven fabric as the second layer of separation material with a separation pore size of 5-10 μm, and use polyvinylidene fluoride microporous filter membrane as the second layer The three-pole separation material has a separation pore size of 0.1-0.5 μm, and the polyethersulfone ultrafiltration membrane is used as the fourth separation material with a separation pore size of 0.02-0.1 μm. Each layer of separation material is separated by a polyester grid with a thickness of 5 mm, and the grid is encapsulated with epoxy resin, and PVC pipelines are embedded in the epoxy resin, and the pipelines of each layer are connected to the four-channel valve On, the cleaning sequence is controlled by adjusting the valve. The entire separation device is a roll separator, the first layer of separation material is aligned with the central tube, and the water i...

Abstract

The invention provides a multi-layer oil-water separator and a working method therefor. The separator comprises a water inlet and a water outlet, wherein a plurality of layers of separating materials are arranged between the water inlet and the water outlet; separating holes are formed in the separating materials; a runner is formed among the separating layers by virtue of a grid; the two sides of the grid are sealed; and the hole diameter of the separating holes is gradually reduced layer by layer from the water inlet to the water outlet. The multi-layer oil-water separator adopts a layer-by-layer filter mode, has good separating effect and relatively high filtration flux, and has cleaning and back cleaning functions, so that the service life of the separator is prolonged. The separator is compact in mechanism, high in integration and convenient for automatic operation and large-scale amplification.

Description

technical field [0001] The invention relates to the technical field of oil-water separation, in particular to a multilayer oil-water separator and a working method thereof. Background technique [0002] The sources of oily sewage are very extensive, such as petroleum ore, textile, food, mechanical processing and many other industries discharge a large amount of oily sewage into the environment. Whether it is industrial oily sewage or domestic oily sewage, it will cause great pollution to the production and living environment. The resulting environmental problems cannot be ignored. Protecting and improving the marine environment and preventing oil pollution are environmental issues that are generally concerned by countries all over the world. Oil pollution not only loses precious oil, but also brings serious consequences to marine life. According to the state and particle size of dispersed oil droplets, oily sewage can be divided into five types: dissolved oil, slick oil...
