Oil and water separator based on micron-nano hiberarchy net membrane and preparation and application method thereof

Abstract

The invention provides an oil and water separator based on a micron-nano hiberarchy net membrane and a preparation and application method thereof. The oil and water separator comprises an oil and water separation device with a micron-nano hiberarchy net membrane, a constant water surface device, a drainage device and a water collection device, wherein the oil and water separation device with a micron-nano hiberarchy net membrane comprises an oil and water mixture liquid collection device and the micron-nano hiberarchy net membrane; the micron-nano hiberarchy net membrane comprises hole-shapedstructure fabric net matrix material with the micron structure and a nanorod array structure material layer vertical to the surface of the material; and the nanorod array structure material layer vertically grows on the surface of the hole-shaped structure fabric net matrix material with the micron structure. The oil and water separator has the characteristics of super hydrophile and underwater super oleophobic performance. The oil and water separator based on a micron-nano hiberarchy net, which is provided by the invention, is stable, efficient and environmentally friendly and the like. Whenthe oil and water separator is used for separating oil and water, water can permeate through the net membrane but oil can not permeate through the net membrane, and therefore the oil and water separator can be reused several times.

Description

technical field [0001] The invention belongs to the technical fields of chemical engineering and functional materials, and in particular relates to an oil-water separation device based on a micro-nano hierarchical structure mesh and a preparation and application method. Background technique [0002] At present, water pollution, especially oil-polluted water incidents occur frequently, mainly including oil exploitation, oil spills, and food, textile, mechanical processing, tanning and other industries producing or discharging a large amount of oil-polluted water into the environment. These polluted water sources seriously threaten the safety and living environment of human beings and creatures, and have become a common problem in the world. Recently, how to achieve effective oil-water separation has attracted more and more attention, and has gradually become an important research topic for researchers. [0003] The emergence of nano-interface materials with self-cleaning pro...

Problems solved by technology

Oil-water separation using omentum coated with hydrogel material has made great progress in solving the problem of oil pollution separation net or omentum, but due to the property of water-swelling hydrogel material, it cannot withstand long-term The water scours, which makes the hydrogel material easy to fall off from the screen substrate, thus limiting its application.

Therefore, there are still considerable challenges in achieving stable, efficient, and environmentally friendly fabrication of water-oil separation devices.
