The device of the oily water separation that the oil field is commonly used has: electrical dehydrator, free water knockout (FWKO), pressure slurry tank etc., wherein electrical dehydrator electric field fluctuation or the electric field play number that collapses is frequent, power-supply unit such as housing, dehydration transformer, insulation boatswain chair and silicon plate damage frequent, and increase the sewage disposal difficulty; Simultaneously free water knockout (FWKO), pressure slurry tank and electrical dehydrator discharge water and all contain the suspended solids of a large amount of not free settlings, poor processing effect, affect injection water quality.Both effectively processed in order to ensure the waterflood system wash-down water, alleviated again the impact to the processing load of built sewage works simultaneously, need to be carried out independent recycling.The employing magnetic separation technique that also has is at present processed the waterflood system wash-down water, and processing efficiency is higher, but the dosing expense is bigger than normal, is difficult to and actual the combining of production.
Summary of the invention
For the deficiency that overcomes existing wash-down water treatment unit poor processing effect, affects the sewage quality, reagent cost is high, the utility model provides a kind of oil field flood pattern wash-down water treatment unit, and this oil field flood pattern wash-down water treatment unit has the advantages that volume is little, processing efficiency is high, reagent cost is low, the secondary pollution product is few.
The technical solution of the utility model is: a kind of oil field flood pattern wash-down water treatment unit, comprise cyclone body, described cyclone body connects the baffle-box import by the one-level water outlet of its end, the outlet of baffle-box connects tubular reactor by lift pump, and tubular reactor is provided with dosing mouth, and the outlet of described tubular reactor connects air floatation machine;
Described air floatation machine inner and upper is provided with slag scraper, the middle part is fixed with several swash plates, and the air floatation machine upper portion side wall is provided with water outlet, be connected with molten gas release head on the sidewall at middle part, be provided with refluxing opening with the sidewall of the relative side of molten gas release head, the air floatation machine bottom is fixed with mud scraper, and has mud discharging mouth on the sidewall corresponding with mud scraper.
Described molten gas release head is relative with the one side that swash plate makes progress.
Corresponding water outlet is provided with regulating weir in the described air floatation machine.
The utlity model has following beneficial effect: owing to take such scheme, swirler connects baffle-box, tubular reactor, air floatation machine successively, and can be to dosing in the tubular reactor, make whole device have the function of eddy flow, flotation, sedimentation, separation, the equipment of having realized is integrated, reduces the volume of settlement separate equipment, has improved treatment effect, the secondary pollution product is few, thus cost saving.
