Description

Multi-functional oil, mud, water separation device

The utility model relates to a kind of oil, mud, water separation device, particularly goes out the separator of silt particle, highly aqueous real estate fluid, also can be used for the purification of water quality of high turbid oil-polluted water.

The mixed liquor of the oil of oil field output, mud, water, adopt method thousands of or that go up big jar of sedimentation of ten thousand stere carry out oil, mud, moisture from, after the sedimentation isolated low wet crude carry a spot of thin silt particle enter carry out oil in oil, gas, water three-phase separator or the electric dehydrator, water separates again.This cover technology exists that equipment volume is big, quantity is many, investment and operating cost height, efficient are low, the silt particle mechanical removal difficulty of sedimentation, artificial clear jar environment are abominable, human body is had injury etc.In addition three phase separator can only carry out oil, gas, moisture from; Electric dehydrator also can only carry out oil, moisture from, all remove the silt particle function.Long-play, silt particle deposit in container and can't discharge, and the back that can only stop production is artificial removes.---liquid separate or liquid---separation Gu cyclone separation process of Yin Jining also can only carry out liquid in recent years, all because of function singleness, be subjected to flow and influence of temperature change can not satisfy the production needs greatly.

For addressing this problem, common way is to adopt centrifugal separation technology.The OFPX-413 centrifugal separator rotating speed that Sweden Alfa Laval company produces reaches the separation that 6000r/min can realize oil, mud, water when above.But concerning general centrifugal separator, all need at a high speed rotation, exist that power consumption is high, consumable accessory is many and little density contrast under the problem of medium separation difficulty.

The purpose of this utility model is that a kind of improved oil, mud, water separation device will be provided, and it can be effectively with the oil under the different densities difference, mud, water separately.

The purpose of this utility model is achieved in that fixed cylinder is housed that cylinder top is welded with the filter cylinder cap in cylindrical shell; Filter cylinder cap center is welded with swirler, and the import of swirler links to each other with tube feed tube outward; Swirler outside filter cylinder crown and shade hoop are welded with oil guide pipe; Between the oil guide pipe on the filter cylinder cap corrugated plating is housed, the filter cylinder cap links to each other with filter cylinder by welding.Liquid at first enters in the swirler, carries out the centrifugation of eddy current coagulation and oil, water, and the oil of separating floats to tank deck, discharges from flowline; High turbid sewage behind the coagulation advances in the circumferential wave card labyrinth, assembles by corrugated plating and carries out the secondary oil removing, and the oil of gathering floats and discharges to tank deck, and sewage is facilitated oarse-grained generation once more by the micro-vortex of " it " font runner generation in corrugated plating labyrinth; Sewage after the secondary oil removing advances annular space and carries out gravitational settling slagging-off, at the bottom of the bulky grain silt particle is deposited to jar; The water side direction flows into filter cylinder, hold back tiny oil droplets and solid particle by filter medium, the oil of filtrate adsorpting aggregation enters in the filter cylinder cap, float to tank deck by oil guide pipe and to discharge, solid particle is discharged by backwash discharge pipeline at the bottom of the jar, water after the purification is discharged from the center outlet pipe of bottom, thereby finishes the separation of oil, mud, water.

The utility model by liquid in tank body, repeatedly change flow direction realize oil, mud, moisture from, so structure does not have running gear; Simultaneously because the starting point does not lie in the high speed rotation of equipment, so it does not have special requirement to the rotary speed and the temperature of liquid; Because falling eddy current coagulation separation, micro-vortex scrubbing in this device, functions such as turbid, corrugated plating oil removing, gravity settling separation slagging-off, filter cylinder filtration, purification are integrated in one, realized that a device multipotency and one are for multistage, simplify handling process, reduced construction investment and energy consumption, made things convenient for production management.
