Problems solved by technology
However, the chemical demulsification method uses chemicals mixed with emulsified oil, and it is very difficult to deal with oil and chemical compounds, which is prone to secondary pollution
The ultrasonic demulsification method is complicated in process, difficult in operation, and too expensive, so it is only suitable for the treatment of a small amount of oily water

The invention discloses a method and device for separating emulsified oil. The device for separating the emulsified oil comprises an ultrafiltration shell; the upper end of the ultrafiltration shell is connected with an upper separating shell in a sealing manner, and the lower end of the ultrafiltration shell is connected with a discharge shell in a sealing manner; the wall of the ultrafiltrationshell is connected with an emulsified oil inlet pipe; the ultrafiltration shell is internally provided with an emulsified oil cavity; an ultrafiltration membrane is arranged in the emulsified oil cavity; a separating outlet at the upper end of the ultrafiltration membrane is arranged in the separating shell which is internally provided with an upper oil-water separation storage cavity; and the separating shell is provided with an oil outlet pipe. The device is simple in structure, can be used for realizing the separation of the emulsified oil in a physical way; and the ultrafiltration membrane is skillfully hung upside down for use, so that the separated oil can be recovered, and the secondary pollution is not generated. Furthermore, the device is simple and low in manufacturing cost and operating cost.
Description
technical field [0001] The invention belongs to oil-water treatment technology, and in particular relates to an emulsified oil separation method and a device thereof. Background technique [0002] Emulsified oil is a mixture of oil and water. The oil contained in emulsified oil will cause great pollution to the environment. Especially the pollution of water bodies. [0003] In recent years, as countries around the world have strengthened their awareness of the protection of oceans, especially adjacent seas and inland rivers, on the basis of Annex IV of MAR-POL73 / 78, various regional discharge standards have been issued, requiring more effective treatment of oily sewage from ships. The National Marine Environment Committee (MEPC) of the International Maritime Organization (IMO) issued Resolution MEPC.107(49) in 2004. New regulations have been made on the treatment and discharge standards of oily sewage from ships. Higher requirements are put forward for oily sewage treatm...
