Centrifugation and dynamic adsorption combination oil-water separation device

Abstract

The invention relates to a centrifugation and dynamic adsorption combination oil-water separation device, and belongs to the field of oil pollution treatment. The centrifugation and dynamic adsorptioncombination oil-water separation device mainly comprises a motor, a rotating device, an oil-water separation device, an oriented nanofiber oil conveying pipe and a collection device. According to thecentrifugation and dynamic adsorption combination method, by use of the principle that oil is light and water is heavy and combination of oleophylic and hydrophobic modification of a fiber membrane,efficient oil-water separation of oil-containing sewage is realized under the action of centrifugal force. The oil-containing sewage in an emulsified state is demulsified through a demulsification filter net membrane, and then enters nanofiber oil adsorption cotton which is of a fluffy space structure, is irregularly arrayed and has high oil adsorption rate, with water blocked outside; the oriented nanofiber oil conveying pipe is embedded into the fiber cotton, so that the adsorbed oil dirt can be sucked out in time under the action of the gravity or external suction, and is conveyed into an oil storage barrel, and then the oil adsorption capacity of the nanofiber oil adsorption cotton is recovered. According to the centrifugation and dynamic adsorption combination oil-water separation device disclosed by the invention, oil-containing sewage treatment which has high separation efficiency and separation capacity and can repeatedly use oil is finally realized.

Description

technical field [0001] The invention relates to an energy-saving and high-efficiency oil-water separation device combined with centrifugal and dynamic adsorption, which belongs to the field of oil pollution treatment. Background technique [0002] With the sharp increase in the demand and utilization of oil products in society, the pollution caused by various oil products is also on the rise. This pollution not only reduces the utilization rate of oil products, but more importantly threatens human health, pollutes the environment, and destroys ecological balance. The sources of oily sewage are very wide, such as petrochemical, mining, mechanical processing, leather, textile, food and other industries, and the discharge volume is large. If it is directly discharged into the water body, it will cause great harm to the natural ecological balance. The traditional treatment methods for oily sewage include physical methods, chemical methods, physicochemical methods and microbial ...
