Abstract
The utility model relates to a cavitation air flotation device which is an improved oily wastewater treatment. The utility model is characterized in that a sedimentation facility with inclined plates (tubes) is arranged at the rear side of a cavitation aerator of a flotation tank, and a precision filter is arranged behind the flotation tank. Utilizing the unique effect of the cavitation air flotation to the oil removal, and the re-separation as well as the subsequent precision filtering of the inclined plates (tubes) to micro oil or micro particle, the utility model not only can remarkably improve the discharge indices of the cavitation air flotation process to reach the oilfield reuse water standard by once treatment, but also has good treatment effect and economic processing. The inclined plates (tubes) in the flotation tank are obliquely arranged according to the treated water flow, so that the precision filter can be arranged in an oblique space below the rear side of the flotation tank, thereby not only increasing the occupied area, but also realizing gravity flow filtration by utilizing the air flotation outlet water potential and omitting the lifting power of the filtering.
Description
Technical field
Utility model is about the improvement to the cavitation air flotation device, relates in particular to a kind of oil-containing wastewater that is used for and handles improved cavitation air flotation device.
Background technology
Cavitation air flotation is used for the oil-polluted water oil removal treatment of oil field, oil plant etc. with its unique aeration mode, has the better treatment effect of more conventional air supporting, has report waste water to contain oil removing rate and can reach more than 95%, thereby be widely used in disposing polluted water in oil.
The prior art cavitation air flotation substantially all is the single cavitation aerator that is provided with in the aeration tank, and revolution Slag Scraping Device in top though people did different the improvement to cavitation air flotation, proposes the air flotation turbo slag-scraper is improved as Chinese patent CN2405925; Chinese patent CN2623676 proposes to install the bubble control valve on aerator, near in the aerator casing deflector is being set; Chinese patent CN2677364 proposes to adopt the V-arrangement housing, and the mud conveying device is set up in the V-arrangement bottom, but still the above-mentioned former basic structure of all basic maintenance.Because prior art cavitation air flotation device all only has only the single air floatation centrifugation, is difficult to reach the requirement of disposing polluted water in oil reuse standard, oil-containing≤5ppm, median particle size≤2 μ m, the high request of SS≤3ppm, therefore still having is worth improved place.
The utility model content
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of cavitation air flotation device that water outlet can reach oil field recycle-water standard of handling is provided.
The utility model purpose realizes that main the improvement is to set up swash plate (pipe) separator in the cavitation air flotation pond, handles water outlet again through smart filtration treatment, thereby oily waste water can be handled to reuse standard, realizes the utility model purpose.Specifically, utility model cavitation air flotation device comprises the air supporting treatment pond, and is arranged at cavitation aerator and revolution Slag Scraping Device in the flotation tank, it is characterized in that flotation tank cavitation aerator rear side has swash plate (pipe) separator, has fine filter behind swash plate (pipe) separator.
The said swash plate of utility model (pipe) separator for water treatment deposition and/or separate oil slick with swash plate or inclined tube, is mainly used in the further separation of fine suspended particulates and tiny oil droplet, handles separating effect to improve.
Fine filter can adopt existing various fine filtering apparatus, as forms such as media filtration, chimney filter filtrations; Can be arranged in the flotation tank, also can be arranged at outside the flotation tank.
For reducing the plant area area, a kind of better is that swash plate in the flotation tank (pipe) is obliquely installed by the processed water flow direction, can be flotation tank rear side below and stays an oblique space, to place fine filter, can reduce occupation area of equipment.
Utility model cavitation air flotation device, owing in the cavitation air flotation device, set up swash plate (pipe) separator, and air supporting is handled water outlet again through the smart filtration of subsequent fine filter, utilize the effect unique of cavitation air flotation to oil removing, add inclined board (pipe) to micro-droplet of oil and particulate separates and subsequent fine is filtered again, not only significantly improved cavitation air flotation and handled effluent index, make it single treatment and promptly can reach oil field recycle-water standard, treatment effect is good, handles economical.Swash plate in the flotation tank (pipe) flows to by processed water and is obliquely installed, and makes fine filter can be located at the oblique space of flotation tank rear side below, neither increases floor space, can utilize air supporting to go out water potential energy again and realize the gravity flow filtration, has omitted to filter to promote power.
Description of drawings
Accompanying drawing is a utility model example structure schematic diagram.
The specific embodiment
Embodiment: referring to accompanying drawing, utility model cavitation air flotation device, comprise flotation tank 13, the flotation tank inhalant region has cavitation aerator 2, there is swash plate Disengagement zone 4 rear end, aeration zone (processing water (flow) direction), there is the taper sludge hopper swash plate below, and there is chain type revolution slag scraper 3 the flotation tank top, and there is not the oil groove of going out 8 the end below.Swash plate is obliquely installed by handling current direction in the flotation tank, and making flotation tank present long down short trailing flank has the inclined-plane, and there is coagulating basin 1 flotation tank front end side, in agitator 1.1 is arranged, under the rear side inclined-plane by supernatant hydroecium 5, the filter formed of filter chamber 6 down.Filter bed of essence 6.1 and filtering layer bed course 6.2 are arranged in the filter chamber.Clean water chamber has outlet pipe 11 and external siphon pipe 7, and siphon pipe 7 is made up of outer tube 7.1 and inner sleeve 7.2.
Pending oil-polluted water enters coagulating basin 1 by top, stirs coagulation through agitator 1.1, enters flotation tank 13 bottoms by the bottom, and through cavitation aerator 2 aerations, coalescent oil slick rises, and is struck off by chain type revolution Slag Scraping Device 3 and enters out oil groove 8 discharges.Air-float water 4 times through the swash plate Disengagement zone is to stream, and subparticle impurity separates to glide through swash plate and enters the lower taper sludge hopper, is discharged by mud discharging mouth 4.1; It is further coalescent in swash plate not separate micro-droplet of oil, rises along swash plate and floats, and handles water outlet and enters gathering ground 12 by rear, mud-removing bucket side top under the swash plate.The air supporting water outlet enters the 6 one-tenth forward flow filterings in filter chamber by vertical water pipe 9, filters water outlet and enters clean water chamber 5 from bottom to top by outlet pipe 10, is discharged by outlet pipe 11.When filter chamber's inner filtration resistance increases, make water level rising in siphon sleeve pipe 7 interlayers, form the siphon backwash at last, make filtrate obtain regeneration, hold back dirt and discharge.
In addition, also available inclined tube replaces swash plate, and the smart filtrate that filters can also adopt other smart filter elements, for example hollow microfiltration tube.
