Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
The structure of this utility model a kind of crude oil emulsion oil-water separation system is as it is shown in figure 1, include sedimentation
Tank 1, settling tank 1 is connected with filter, and filter is connected with crude heat exchanger 2, crude heat exchanger 2
Being connected with pipe-line mixer 3, pipe-line mixer 3 is connected with electric pulse 4, electric pulse 4 and centrifuge 5
Connecting, the outlet of centrifuge 5 is connected with water tank 6, and the oil-out of centrifuge 5 is connected with fuel tank 7,
The centrifugal slag outlet of centrifuge 5 is connected with dreg-storing box 8；Have dosing mouth 9 on pipe-line mixer 3, add
Medicine mouth 9 is provided with medicine storage box.Wherein, filter is y-type filter 10 and accurate filter 11.
Connected by force (forcing) pump 12 between y-type filter 10 and accurate filter 11.Force (forcing) pump 12 is G type
Screw rod booster pump.The filter element precision of accurate filter 11 is 75～150 mesh.The model of electric pulse is
FJDC-15/T, centrifuge 5 is DHK Y470 type centrifuge, is provided with tee T at dosing mouth 9, three
The other two port of siphunculus outlet pipe with two dosing pumps respectively is connected, the water inlet pipe of two dosing pumps

Operation principle and the process thereof of this utility model produced water treatment system be:
Crude oil emulsion in settling tank is entered in y-type filter by wired hose, filters out emulsion
Middle mesh number, more than the impurity of 20 mesh, runs for follow-up equipment and reduces abrasion and mechanical breakdown, Impurity removal
Amount is about total solid 10%；Then pass through the emulsion after primary filter and enter G type screw rod booster pump,
This pump has the supercharging transport adapting to thickness emulsion, and emulsion passes through G type screw rod booster pump front and back end pair
Clip butterfly valve controls liquid inlet volume, to maintain relatively stable equipment treating capacity；Emulsion after supercharging
By double-filtration precision 75 mesh accurate filter, then through one-level 150 mesh accurate filter, by breast
Changing the overwhelming majority filtering foreign such as graininess impurity and felt plastic bag in liquid, accurate filter is isolated
Impurity type material then by filter lower end slag-drip opening, outer flow back to settling tank bottom, then as
Bottom settling tank, sediment together enters body refuse processing system, and the purest emulsion is fed directly to crude oil
In heat exchanger, through secondary filter, emulsion is removed about 60% amount of solid, is carried for follow-up precision equipment
Supply preferable operational effect；
Enter the emulsion in steam crude heat exchanger, through 90 DEG C of high-temperature steam heat exchange, pass in and out emulsion
Temperature difference is 10～15 DEG C, promotes that emulsion carries out further breakdown of emulsion；Emulsion after heating enters pipe
In road blender, two dosing pumps that blender connects, 50mg/L PAM (polyacrylamide) chemicals dosing plant
Liquid inlet volume is 15%～20% aperture, 50mg/L bodied ferric sulfate chemicals dosing plant 20% aperture, medicine and breast
After changing liquid mixing, further breakdown of emulsion；Emulsion mixed with medicament enters in electric pulse emulsion breaking device,
Its Main Function is to introduce charged particles by ultrasonic dither to produce emulsion demulsification,
Ultrasound wave in the range of 20KHz～40KHz has good dehydrating effect to emulsion, can deviate from emulsifying
The moisture of 70% in liquid；Emulsion after preliminary hydro-extraction, enters crude oil emulsion specialized high-speed centrifuge,
Through centrifuge 6000r/min high speed rotating, crude oil and water and SOLID ORGANIC impurity are because of density variation quilt
Being successfully separated, then oil, water, slag three-phase discharge high speed centrifuge by respective passage, so that emulsifying
The thorough breakdown of emulsion of liquid；Separated oil enters fuel reserve tank, reaches certain liquid level booster pump and starts, is beaten by crude oil
Enter in sewage network；Slag enters dreg-storing box, the most periodically packs outward transport.
