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.
