Description
Technical field
The utility model belongs to technical field of sewage, specifically, relates to a kind of oil trap.
Background technology
Oil trap (oil separator) is to utilize the difference of specific gravity of oil and water, separated a kind of pre-treatment structures of removing the suspension oil that in sewage, particle is larger.Petroleum industry, petrochemical industry and mechanical processing industry are discharged a large amount of oily(waste)waters in process of production.These oily(waste)waters can pollute as entered water body, and soil pores can be stopped up in irrigated farmland, harmful plant growth.As the oil product in waste water is recycled, not only can avoid the pollution to environment, can obtain considerable economic return again.
Existing oil trap is generally two tanks and forms, the first tank is isolated oil, sewage is passed in the second tank, again the sewage in the second tank is passed in next treatment facility, but find in reality, owing to can not reaching absolute static in oil trap, can be with a small amount of greasy dirt in sewage, the sewage after therefore processing like this still has a large amount of greasy dirts thoroughly not disposed.
Prior art shortcoming: existing oil trap deoiling effect is poor, and oil removal efficiency is low, contains more oil in water outlet.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of deoiling effect, oil trap that oil removal efficiency is high of improving.
The utility model object is achieved in that a kind of oil trap, its key is: comprise the first tank, the second tank and the 3rd tank, described the first tank communicates with the second tank bottom, described the second tank communicates with the 3rd tank top, this second tank is communicated with by unidirectional return water pipe with the bottom of the 3rd tank, make the 3rd tank can be by described unidirectional return water pipe to the second tank water flowing, described the first tank be provided with water inlet pipe, in described the second tank, is provided with rising pipe.
Adopt said structure, by water inlet pipe, in the first tank, pass into sewage, greasy dirt floating, contain a small amount of sewage and from bottom, pass into the second tank, greasy dirt floating, greasy dirt and sewage flow into the 3rd tank from top, under the first tank flowing water promotes, oil slick above the second tank flows into the 3rd tank, finally the 3rd, above tank, forbid, form oil slick layer, the 3rd tank stopping due to threeway, upper strata oil slick can not enter the second tank, and degreasing water level is below oil slick layer, by the unidirectional return water pipe sewage that will deoil, be back in the second tank, further deoil, effect and the efficiency of degreasing have been improved.
Above-mentioned unidirectional return water pipe is provided with unidirectional stop valve, and the mounting height of this unidirectional return water pipe feed-water end is 1/3rd of described the 3rd tank height, and the water side of described unidirectional return water pipe is positioned at the bottom of described the second tank.
Adopt said structure, unidirectional stop valve energy bonding can only reflux the sewage of the 3rd tank to return water pipe toward the second tank, and the feed-water end of certain mounting height, the one, for the sewage that can will deoil passes into the second tank, the 2nd, prevent the feed-water end of the unidirectional return water pipe of sludge blockage under deposition; The position sewage of rising pipe water side, without oil, has greatly reduced the greasy dirt content in water outlet, and facilitates the extracting of impeller pump.
Above-mentioned the first tank communicates by through hole with the second tank bottom, and the partition wall top of described the second tank and the 3rd tank is provided with "T"-shaped Y-tube.
Adopt said structure, the greasy dirt by liquid level in Y-tube the second tank can flow to the 3rd tank, and can prevent that greasy dirt from refluxing.
One end of above-mentioned Y-tube is vertically positioned at described the second tank through the partition wall of described the second tank and the 3rd tank, and another two ends are positioned at described the 3rd tank, and any two ends of described Y-tube is not all positioned at same level.
Adopt said structure, the greasy dirt by liquid level in Y-tube the second tank can flow to the 3rd tank, and the greasy dirt that prevents that can also the short period of time refluxes.
The above second bottom of gullet is provided with the dividing plate perpendicular to this bottom, this dividing plate is divided into two chambers by described the second tank, the height of described dividing plate is lower than described Y-tube installation site, higher than described through hole, the water side of described unidirectional return water pipe and described rising pipe are all positioned at the chamber near described the 3rd tank.
Adopt said structure, in two chambers, in a chamber, be the sewage that the first tank flows into, contain a small amount of greasy dirt, under the stopping of dividing plate, can not sneak into another chamber, and in another chamber, have that the first tank flows into, standing obtain without oily water, also have the 3rd tank to reflux and come without oily water, therefore further guaranteed that sewage that extracting goes out, without oil, has improved deoiling effect.
Above-mentioned rising pipe is provided with impeller pump, and this impeller pump is positioned at outside described the second tank, and the feed-water end of described rising pipe is near the bottom of described the second tank.Adopt said structure, guaranteed in sewage that rising pipe extracts without oil.
Beneficial effect:
The utility model is a kind of oil trap, simple in structure, and oily(waste)water enters the 3rd tank from top, without oily water, from the bottom of the 3rd tank, be back to the second tank, form circulation, guarantee that the oil content of wastewater extracting from the second bottom of gullet is lower, deoiling effect is better, and oil removal efficiency is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
