Description
Technical field
The utility model relates to a kind of coagulation electrolytic separation device in petrochemical industry, particularly a kind of coagulation electrolytic separation device for oil-bearing sewage for ternary combination flooding in oil field process.
Background technology
Current oil extraction-generated waste water oil removing, turbid, viscosity reduction is gone mainly to take the technology such as natural subsidence, coagulating sedimentation, filtration, air supporting.Wherein, natural sedimentation mainly utilizes oil and water-mass density official post oil to float, and reaches the object of oily water separation; Coagulating sedimentation mainly utilizes different coagulating agent, flocculation agent to combine, and makes water-borne glue body " de-steady ", takes off particle and small suspended substance in the colloid surely and assembles, thus remove the suspended matter in water; Filter and mainly refer to that water body flows through certain thickness filter bed, and then remove oil-containing, suspended substance, the colloid in water; Air supporting can be roughly divided into gas distribution By Bubble-floating Method, electric floating method, biology and chemical floatation treatment, dissolved air flotation, general electrolytic air supporting is the direct current passing into 5-10V in sewage, thus generation micro-bubble, and oil droplet and the solid particulate item water surface in bubble surface attached water are floated, thus obtain oil, solid is separated with water.Above-mentioned technique mainly has the following disadvantages: (1) Technology is numerous and diverse, single technical finesse function singleness; (2) natural sedimentation effectively can remove the suspension oil in water, but bearing sewage for ternary combination flooding in oil viscosity is large, and Zeta potential is high, uses natural sedimentation effectively cannot remove suspended substance in water and colloid; (3) coagulating sedimentation effectively can remove colloid in water and suspended substance, but due to the light specific gravity containing oil ratio water in water, therefore uses coagulative precipitation device to be difficult to remove oil-containing in water; (4) existing air-floating apparatus effectively can remove various hydrophobic substance in water, but its disengaging time is short, and inherently cannot change the stability of oily(waste)water.
Summary of the invention
Technical problem to be solved in the utility model overcomes the problem that the existing air-floating apparatus existed in background technology is difficult to effectively remove oil-containing in suspended substance and water, and a kind of coagulation electrolytic separation device for oil-bearing sewage for ternary combination flooding in oil field process is provided, this is used for the coagulation electrolytic separation device of oil-bearing sewage for ternary combination flooding in oil field process, effectively can remove the suspended substance in sewage and oil-containing, realize the solid-liquid separation of solution.
The invention for solving the technical problem reaches by following technical scheme: this is used for the coagulation electrolytic separation device of oil-bearing sewage for ternary combination flooding in oil field process, comprise coagulation bucket, air flotation zone, mobile receipts mud car, described coagulation bucket, mobile mud car of receiving are placed in both sides, air flotation zone respectively; Described air flotation zone is divided into exposure chamber and separate chamber by vertical steel plate; Described exposure chamber is communicated with separate chamber's opened upper end, and bottom has discharge outlet; Described coagulation bucket feeding line connects fresh feed pump and dosing import, and described top, separate chamber and bottom are screwed 2 mud scrapers respectively, and top is wheeled mud scraper, and bottom is spiral mud scraper, and described top, separate chamber has backwater interface; Described coagulation bucket is connected with exposure chamber by flexible pipe, top, exposure chamber and middle part grid for welding plate, dissolved air release respectively; Described dissolved air release pipeline connects dissolving, and dissolving connects reflux pump and air compressor machine; Described reflux pump pipeline connects backwater interface, and mobile receipts bottom mud car has discharge outlet, and mobile mud car upper opening of receiving is placed in the oblique below of wheeled mud scraper.
The utility model can have following beneficial effect compared with above-mentioned background technology: this coagulation electrolytic separation device being used for oil-bearing sewage for ternary combination flooding in oil field process is owing to adopting said structure, effectively the removal efficiency of bearing sewage for ternary combination flooding in oil can be reached 90%, viscosity clearance reaches 40%, reaches more than 50% containing oil removing rate.
