A kind of constant current mode oil eliminator
?
Technical field
The present invention relates to a kind of oily(waste)water treatment facility, particularly a kind of constant current mode oil eliminator.
Background technology
Along with constantly rising up into of oil-field development, all can produce the extraction of cubical more than 200,000,000 sewage every year, but the utilization ratio of sewage is merely 80%, a large amount of residue sewage is invalid to be recharged the stratum or effluxes, and also will consume more than 2,000 ten thousand cubical clear water simultaneously.Solve the treatment process of recovered water, with effectively alleviating the contradiction that petroleum industry wastewater disposition and clear water consume.
At present, already extract surplus liquid to metallurgy, the oil removing in the chemical industry oily liq, general oil eliminator adopts charcoal absorption, filtration, unit efficiency a little less than, and generally remove the structure imperfection that oil system adopted, filler is prone to overflow, has increased cost greatly.
Summary of the invention
Goal of the invention: to the deficiency of prior art, the invention discloses a kind of simple in structurely, can effectively remove smeary constant current mode oil eliminator in the waste water.
Technical scheme: the invention discloses a kind of constant current mode oil eliminator; Said constant current mode oil eliminator comprises that casing vertically is arranged on the division plate in the casing; Be horizontally set on the last screen plate in the casing; Be horizontally set on the following screen plate in the casing, division plate is provided with overflow plate, and overflow plate is the swash plate that tilts to the clean water basin direction; Said screen plate down is arranged on the screen plate below, and said going up between screen plate and the following screen plate left one section space; The upper limb of said division plate is higher than the level height of screen plate, and said division plate is divided into filtering basin and clean water basin with casing; Said overflow plate is lower than the casing top; Said filtering basin bottom is provided with water-in, and the clean water basin bottom is provided with water outlet; Said casing top is provided with oil outlet, height such as the upper limb of overflow plate and oil outlet.
Beneficial effect: constant current mode oil eliminator disclosed by the invention, solved the problem that floating oil can not fully be removed and collect, easy and simple to handle, no energy consumption, low cost.
Description of drawings
Accompanying drawing is the structural representation of constant current mode oil eliminator.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
The invention discloses a kind of constant current mode oil eliminator; Said constant current mode oil eliminator comprises, casing 1 vertically is arranged on the division plate 2 in the casing 1; Be horizontally set on the last screen plate 4 in the casing 1; Be horizontally set on the following screen plate 5 in the casing 1, division plate 2 is provided with overflow plate 3, and overflow plate 3 is the swash plate that tilts to clean water basin 7 directions; Said screen plate 5 down is arranged on screen plate 4 belows, and said going up between screen plate 4 and the following screen plate 5 left one section space; The upper limb of said division plate 2 is higher than the level height of screen plate 4, and said division plate 2 is divided into filtering basin 6 and clean water basin 7 with casing 1; Said overflow plate 3 is lower than casing 1 top; Said filtering basin 6 bottoms are provided with water-in 8, and clean water basin 7 bottoms are provided with water outlet 9; Said casing 1 top is provided with oil outlet 10, the upper limb of overflow plate 3 and oil outlet 10 height such as grade.
When said constant current mode oil eliminator was worked, solution was got into by water-in, filtered through screen plate from bottom to top; Through the overflow plate overflow; Profit produces and separates, the water level come-up that separated elaioleucite rises along constant current, and the oil reservoir on the liquid level is reclaimed by oil outlet; Solution is discharged by water outlet after then filtering for 2 times through the screen plate in the clean water basin.
The invention provides a kind of thinking and method of constant current mode oil eliminator, realize that specifically the method for this technical scheme and approach are a lot, the above only is a preferred implementation of the present invention; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching; These improvement and retouching also should be regarded as protection scope of the present invention, and all available prior art of each integral part not clear and definite in the present embodiment realizes.
