Abstract

A kind of sewage plant Water Tank air-float degreasing device nitrogen reliever, comprising: housing (1), screw rod (2), spring (3), guide plate (4), block head (5), outlet (6), setting nut (7).Its housing (1) is round shape, the center, the left side of housing (1) is provided with tapered hole, four tapped through holes (A) are provided with around tapered hole, the right is provided with outlet (6), on have four screw rods (2) of setting nut (7) through the through hole (B) on the through hole (C) on guide plate (4), spring (3), block head (5), be connected with the tapped through hole (A) on housing (1), be arranged on the inner chamber of housing (1).The utility model to be applicable in the sewage primary oil removal tank of oilfield sewage station in nitrogen air flotation oil removal technique, the nitrogen dissolved in dissolved air water is easily separated out, the sump oil formed in microvesicle adhesion sewage floats, play quick deoiling effect, prevent solution gas from separating out in advance, improve daf efficiency, achieve the voltage stabilizing conveying of sewer line.

Description

Sewage plant Water Tank air-float degreasing device nitrogen reliever
Technical field
The utility model relates to oilfield sewage station sewage primary oil removal tank nitrogen-air-float degreasing device annex, specifically a kind of sewage plant Water Tank air-float degreasing device nitrogen reliever.
Background technology
Nitrogen-oil removal by air bubbling technique is used in the sewage primary oil removal tank of current oilfield sewage station, middle nitrogen formation dissolved air water soluble in water under the effect of the pressure in microvesicle generation tank, dissolved air water should transport to primary oil removal tank under the operating mode of equipressure, in tank, reliever enters oil removing pot central tube, because central tube internal pressure is low, therefore the nitrogen dissolved in dissolved air water is separated out, and the sump oil formed in microvesicle adhesion sewage floats, and plays the effect of quick deoiling.But in actual production, in oil removing pot, do not design reliever, the equipressure conveying of dissolved air water cannot be ensured, after dissolved air water flows out microvesicle generation tank, because pressure reduces, namely etc. do not enter oil removing pot central tube separates out nitrogen in pipeline, greatly have impact on deoiling effect.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of sewage plant Water Tank air-float degreasing device nitrogen reliever.
Technical solutions of the utility model comprise: housing, screw rod, spring, guide plate, block head, outlet, setting nut.The housing of described sewage plant Water Tank air-float degreasing device nitrogen reliever is round shape, the center, the left side of housing is provided with tapered hole, four tapped through holes are provided with around tapered hole, the right is provided with outlet, on have four screw rods of setting nut through the through hole on the through hole on guide plate, spring, block head, be connected with the tapped through hole on housing, be arranged on the inner chamber of housing.
Housing right-hand member outlet in above-mentioned sewage plant Water Tank air-float degreasing device nitrogen reliever is provided with annular flange flange.
The elastic force of the spring in above-mentioned sewage plant Water Tank air-float degreasing device nitrogen reliever is regulated by setting nut.
Block head in above-mentioned sewage plant Water Tank air-float degreasing device nitrogen reliever is the superimposed body of circular cone and plectane, and plectane periphery is provided with four through holes.
The circular cone of block head in above-mentioned sewage plant Water Tank air-float degreasing device nitrogen reliever coordinates with the tapered hole of housing.
The beneficial effects of the utility model are: to be applicable in the sewage primary oil removal tank of oilfield sewage station in nitrogen-oil removal by air bubbling technique, the nitrogen dissolved in dissolved air water is easily separated out, the sump oil formed in microvesicle adhesion sewage floats, play quick deoiling effect, prevent solution gas from separating out in advance, improve daf efficiency, realize the voltage stabilizing conveying of sewer line.
Accompanying drawing explanation
Fig. 1-the utility model master looks complete section structural representation.
In figure, 1. housing, 2. screw rod, 3. spring, 4. guide plate, 5. block head, 6. export, 7. setting nut; A. tapped through hole, B, C. through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, sewage plant Water Tank air-float degreasing device nitrogen reliever is made up of housing 1, screw rod 2, spring 3, guide plate 4, block head 5, outlet 6, setting nut 7.The center, the left side of the cylindrical shell 1 of described sewage plant Water Tank air-float degreasing device nitrogen reliever is provided with tapered hole, four tapped through hole A are provided with around tapered hole, the right is provided with outlet 6, on have four screw rods 2 of setting nut 7 through the through hole B on the through hole C on guide plate 4, spring 3, block head 5, be connected with the tapped through hole A on housing 1, be arranged on the inner chamber of housing 1.During use, the screw rod 2 on housing 1 being connected with dissolved air water water underwater flange, by regulating the regulating nut 7 of four springs 3 to adjust spring travel, ensureing that block head 5 has enough snap-in forces.When carrying out water pressure and exceeding the snap-in force of spring 3, current will promote block head 5 outwards movement, occur space between the tapered hole of block head 5 and housing 1, and current flow out and enter outlet 6 between space.Because the pressure exported in 6 is large tank static pressure, its value is much smaller than carrying out water pressure, and after therefore water enters outlet 6, nitrogen entrained in water is separated out and formed bubble, enters central tube, reaches the object of bubble removal sump oil and impurity.
