Description

Combined type sump oil separating and reclaiming device in jar

Technical field

The utility model relates to the petro-chemical waste water treatment retrieving arrangement, is specifically related to combined type sump oil separating and reclaiming device in the jar.

Background technology

In the sewage treatment process such as oil field, refinery, mainly be to handle through floor space big settling bowl or slurry tank, equipment manufacturing cost is very high; Oily(waste)water gets in the slurry tank, need the regular hour to carry out sedimentation and handle and could oil product be separated to the liquid level surface, but the liquid level of this liquid separated is not very stable, is difficult to collect at any time water-free surperficial oil slick.

Owing to itself have a large amount of silt, suspended substance and other impurity in the oily(waste)water; In the sewage settling process, because action of gravity, the silt that particle is bigger in the oily(waste)water, suspended substance and other impurity can be through gravity settling to pot bottoms; Form slurry tank bottom mud; In the oily water treatment process, add flocculation agent particle and suspended substance and the flocculation of other impurity in the oily(waste)water are generated under the bigger settling of floccus, just possibly get into filtering system with the sedimentation water outlet at any time after in slurry tank, running up to certain altitude, understand serious harm like this to Sewage treatment systems; Form the WWT vicious cycle, influence water conditioning.

Spoil disposal in the existing slurry tank in the oily water treatment, oil slick reclaim main rely on artificial, but manual handling exist labour intensity big, to surperficial oil slick collect untimely, profit natural sedimentation disengaging time is long, blowdown is untimely, discharge mud causes new problems such as environmental pollution.

Summary of the invention

The purpose of the utility model is to deficiency of the prior art; A kind of minimizing environmental pollution is provided, reduces labor intensive, in time separates oil slick in the sewage, and can oil slick, silt reasonably be discharged into combined type sump oil separating and reclaiming device in jar outer jar.

For accomplishing above-mentioned purpose; The technical scheme that the utility model adopts is: combined type sump oil separating and reclaiming device in jar; Comprise slurry tank, be installed in sedimentation device, used oil pipe, return water pipe in the interior liquid-inlet pipe of slurry tank, cyclone separator, take off pipe, oil spilling mouth, the oil-collecting device that floats, the jar; Wherein liquid-inlet pipe connects cyclone separator, and cyclone separator is installed in the jar on the sedimentation device, its underpart with jar in sedimentation device be communicated with, the oil spilling mouth is installed on the cyclone separator; Unsteady oil-collecting device comprises oil header, oil outlet pipe, traversing mechanism, transition pipeline, the unsteady oil receiving equipment structure that connects successively; Said used oil pipe is connected sedimentation device top in the jar, and said return water pipe is installed in sedimentation device bottom in the jar, and said take off pipe is installed in the slurry tank middle part.

The beneficial effect of the utility model: the setting of used oil pipe, return water pipe has guaranteed that discharging smeary separating effect is thorough; Unsteady oil-collecting device has been guaranteed the timely recovery of oil product; Sedimentation device makes sediment deposition separation and discharging in time in jar, can not cause secondary environmental pollution; Spoil disposal during oily water is handled, oil slick reclaim and no longer rely on manual work, have reduced operator's labor intensive.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the utility model structural representation.

Among the figure: 1, slurry tank, 2, liquid-inlet pipe, 3, cyclone separator, 4, take off pipe, 5, the oil spilling mouth; 6, oil header, 7, transition pipeline, 8, traversing mechanism, 9, the oil receiving equipment structure floats; 10, float, 11, used oil pipe, 12, jar in settling vessel, 13, return water pipe; 14, mounting bracket, 15, oil outlet pipe, 16, shore pipe, 17, receiving port.

Embodiment

As shown in Figure 1, combined type sump oil separating and reclaiming device in jar, comprise slurry tank 1, be installed in liquid-inlet pipe 2 in the slurry tank, cyclone separator 3, take off pipe 4, oil spilling mouth 5, the oil-collecting device that floats, jar in sedimentation device, used oil pipe 11, return water pipe 13; Wherein liquid-inlet pipe 2 connects cyclone separators 3, and cyclone separator 3 is installed in the jar on the sedimentation device, and sedimentation device is communicated with in its underpart and the jar, and oil spilling mouth 5 is installed in cyclone separator 3 upper ends; Unsteady oil-collecting device comprises oil header 6, oil outlet pipe 15, traversing mechanism 8, transition pipeline 7, the unsteady oil receiving equipment structure 9 that connects successively; Said used oil pipe 11 is connected sedimentation device top in the jar, and said return water pipe 13 is installed in sedimentation device bottom in the jar, and said take off pipe 4 is installed in slurry tank 1 middle part.

Sedimentation device comprises settling vessel 12 in the jar, mounting bracket 14, shore pipe 16 in said jar, and settling vessel 12 is installed on the mounting bracket 14 in the said jar, and shore pipe 16 is installed in settling vessel 12 bottoms in the jar.

Said unsteady oil receiving equipment structure 9 two ends are provided with two floats 10, centres a receiving port 17 are set.

Liquid gets into cyclone separator 3 through liquid-inlet pipe 2; In cyclone separator 3, produce rotational flow separation; Oil, water, silt are separated; Oil product is injected into the liquid surface in the slurry tank 1 through oil spilling mouth 5, and water, silt get into settling vessel 12 in the jar, and the oil slick that is injected into the liquid surface can be collected oil header 6 then by outside oil outlet 15 drain tanks with oil through transition pipeline 7, traversing mechanism 8, the oil receiving equipment structure 9 of the oil-collecting device that floats; Water, silt get into settling vessel 12 in subordinate's jar; Sediment settlement is in the bottom; And the sewage that is separated imports in the slurry tank 1 through return water pipe 13 once more; Owing in jar, inevitably can sedimentation go out a small amount of oil product in the settling vessel 12, so this part oil product imports through used oil pipe 11 again, and liquid is surperficial in the slurry tank compiles with the oil slick of separating; Import a jar interior sewage through return water pipe 13, through in slurry tank, carrying out gravity settling once more; Mud is discharged from shore pipe 16, can pass through the direct collection and treatment of collecting device, and the water after separating can be discharged from water port 4.

This covering device has been realized three grades of separating effects on technology, promptly a rotational flow separation, twice gravity separation, oily water are handled and reached thorough separation.
