Novel oil, mud and water separation device

Abstract

The invention discloses a novel oil, mud and water separation device. A separation pool is a circular pool, and a stirrer, a steam floatation component, a heating coil and an oil receiving tank are arranged in the inner pool of the separation pool. A pool body oil receiving pipe orifice, a pool body water outlet pipe orifice and a pool body liquid inlet pipe orifice are formed in the pool wall of the separation pool, and a pool body mud discharging pipe orifice, a pool body heating pipe orifice and a pool body steam floatation pipe orifice are formed in the pool bottom of the separation pool. The separation pool is connected with a mud lifting pump, a water receiving pump, a mud discharging pump and heat source equipment through a liquid inlet manifold, an oil receiving manifold, a water outlet manifold, a mud discharging manifold, a heating manifold and a steam floatation manifold. The device integrates water purification and mud removal functions of stewing pyrolysis, stirring scrubbing, gas floatation for oil removal, vortex coagulation and static settling, and realizes integration replacing multiple stages and one machine with multiple purposes. The device is small in size, light in weight, easy in prying mounting, and convenient for a vehicle-carried site for mobile use.

Description

technical field [0001] The invention relates to an oil-containing mud oil, mud and water separation device for treating waste mud from drilling in an oil field and deposition mud in a station oil and water storage tank, in particular to a novel oil, mud and water separation device. Background technique [0002] At present, in the treatment of waste drilling mud in oilfields, hauling, recycling and centralized treatment are mostly used. The purified water after treatment is discharged or recharged into the formation, which has high freight costs and waste of water resources. In the process of crude oil storage and transportation, oily mud is deposited at the bottom of the tank. Many of them are stored in ponds, which will take up a large area after storage for a long time, and will be oxidized and deteriorated. It is difficult to process and recycle after becoming aged oil, which is a waste of crude oil resources and pollutes the environment. In order to solve this problem...

Problems solved by technology

[0002] At present, in the treatment of oilfield drilling waste mud, hauling, recycling and centralized treatment are mostly used. The purified water after treatment is discharged or recharged into the formation, resulting in high freight costs and waste of water resources. In the process of crude oil storage and transportation, oily mud is deposited at the bottom of the tank. It is often used for storage in ponds, which takes up a large area after storage for a long time, and oxidizes and deteriorates. It is difficult to process and recycle after it becomes aged oil, which wastes crude oil resources and pollutes the environment.

In order to solve this problem, the Chinese patented oil, mud and water separation device (ZL201220640 557.5) was used to carry out the separation test of oil, mud and water in oily mud. A lot of aging oil, low liquid temperature, and poor mud fluidity. The treatment of oily mud is not well considered, resulting in serious blockage of the device and making it impossible to operate. For this reason, the problems of high freight, heavy pollution of the environment, waste of oil and water resources have not been solved.
