the micro-bubble that exists in the liquid is activated under the ultrasonic wave effect and shows vibration; expand; shrink; a series of dynamic processes such as collapse; the sound field concentration of energy is got up; follow air bubble to collapse moment; energy with its high concentration in the little space in liquid discharges; form thundering high temperature; high pressure; strong shock wave; the cavitation effect of extreme physical condition such as jet; thereby the oil that is attached on the sand grain is peeled off, and the colloid and the pitch particle of ageing smashed.Simultaneously the air supporting potential energy field is utilized the microbubble in the dissolved air water that the steam generator 8 of air dissolving system produces, and fitting together with suspension oil droplet in the water rises to liquid surface with bubble and form oil slick, makes profit obtain separating.The eddy flow guider 27 that while is provided with at cavitation air supporting three phase separator 7 tank body internal upper parts, make the greasy filth slurry with certain kinetic energy, promptly with the pressure of 0.1～0.4MPa, per hour 5～40 cubic metres flow is when tangentially entering tank body, in separator, form the eddy flow kinetic energy field of a liquid, profit sand grain in the greasy filth slurry is collided through mutual continuous high speed, cause tiny oil droplets to gather and float to the center, colloid, pitch are fully emulsified, and utilize the density variation of profit silt, the profit silt in the cavitation air supporting three phase separator 7 is well separated.By the flow of control slush pump 6 and slush pump 10, most of oil and low amounts of water are overflowed from cavitation air supporting three phase separator 7 tops, enter profit storage tank 9, enter oil-water separation tank 18 through oil pump 30.Be deposited on the mud and the water of cavitation air supporting three phase separator 7 bottoms, again through grug feeding jar 11 from the bottom of cavitation air supporting three phase separator 7 add contain the flocculant of 0.1%～0.2% PAMC (PAM) after, by slush pump 10 through the pressure of pipeline with 0.03～0.4MPa, 5～40 cubic metres flow per hour, tangential input column-shaped barrel from cyclone separator 12, the centrifugal force that the thick and heavy grains of sand are subjected in the strong cyclone field of cyclone separator 12 is big, thrown to the eddy flow wall and discharged to the bottom by the spiral trajectory backspin, after clean husky dewater unit 15 processing, be transported to the forming and hardening place; The centrifugal force that thin mud particle is subjected in thin and light is little, and being formed centrally in conical shell moves on the inside spin flow direction overflows, and makes most of liquid of thin mud in containing enter centrifuge 14 by gravity tank 13.In centrifuge 14 under the effect of centrifugal force field, the solid formation that proportion is bigger is deposited on the rotatory drum wall, under the effect of auger conveyor, rely on the difference rotating speed, mud after the dehydration after discharging, the small end mud mouth of circular cone rotary drum is delivered to the forming and hardening place, the oil of light specific gravity and water overflow from centrifuge 14 delivery ports through return duct, enter profit storage tank 16, enter oil-water separation tank 18 through centrifugal pump 17.The thin mud of oil-water separation tank 18 enters press type filter 20 under sludge pump 19 promotes, deliver to the forming and hardening place after thin mud is pressed into filter cake, and filtrate returning enters oil-water separation tank 18.After profits in the oil-water separation tank 18 utilized proportion separately different naturally sink-float is separated, the oil that the Oil scraper 21 by corresponding setting it on will float was scraped into oil sump, squeezes into the petroleum pipeline recycling through oil pump 31; And the water in the oil-water separation tank 18 after oil-water separation tank water pump 22 is squeezed into heating furnace 23 heating, is delivered to foreign material except that selecting machine 2 recycling by heat-exchanger pump 3 again.
After the clean husky dehydration that cyclone separator 12 is discharged, carry, after can stirring by 25 dosings of dosing mixer routinely, enter 26 moulding of forming and hardening machine again, be put into to solidify and hang the place and solidify and hang, make the higher construction material of intensity through belt conveyor 24; Mud is then made the lower slightly decoration construction material of intensity in the forming and hardening place by above-mentioned same process route.
The present invention not only makes discarded object be utilized effectively, and reduces the wasting of resources, greatly reduces the cost of oily sediment purified treatment simultaneously.This purifying treatment method and system are applicable to and handle the oily sediment that produces in the various oilfield processes.
Above-mentioned detailed description of this pollution-free oil-containing sediment and purification processing method and treatment system being carried out with reference to embodiment; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
