CN2533932Y - Efficient turbulent phase change accelerating oil-water separator - Google Patents

Abstract

The utility model discloses a high efficient oil-water separator, which uses turbulence to stimulate transformation, pertains to the technical field of power supply and power transformation equipment. The structure is that a nozzle is arranged on the centerline in an inlet of a tubular turbulence generator. A diffusion tube shaped like a trumpet is arranged in the turbulence generator. A wide port of the diffusion tube faces an outlet of the turbulence generator. A thin port of the diffusion tube faces the nozzle of the turbulence generator. The utility model has the advantages of good effect in processing not only emulsified water but also micro water, leaving the processed oil with water content less than 5 milligrams per kilogram (ppm).

Description

High-efficiency turbulent flow is urged the phase transformation oily-water seperating equipment

Technical field:

The utility model belong to send out, for, converting equipment technical field.

Background technology:

Power station steam turbine and high-power transformer are in operation, to contact with steam inevitably and suck part moisture, also can produce pernicious gas during transformer work simultaneously, cause oil abominable, cause oily serious emulsification, reduce the greasy property and the insulating properties of oil, quicken the corrosion of oily oxidation deterioration and metal parts simultaneously, influence the safety of steam turbine and transformer, need handle.When handling, not only to remove impurity wherein, also to remove wherein moisture and pernicious gas.

At present domestic traditional oily-water seperating equipment is varied, and its operation principle is divided into two big classes: the one, and employing polywater element promptly makes water be condensed into that large water drop is old to fall draining with special substance.The 2nd, adopt vavuum pump, even the constantly evaporation under vacuum state of dissolving water is discharged through vavuum pump.They are not that to filter the oil emulsion performance poor, be exactly have power consumption height, complex structure, volume is big, clumsiness is heavy, cost is high and shortcoming such as filtration time length.

Existing a kind of vapour-liquid two-phase turbulent flow oily-water seperating equipment patented technology (01250463.7) through testing moisture and moisture in the transformer oil and the pernicious gas that can remove fast in the steam turbine oil, especially can be handled emulsified water.But owing to introduce air, total air content increases thereupon in the oil, and this air content does not influence the operate as normal of steam turbine oil, but the increase of air content influences the operate as normal of transformer with oil.Air has certain humidity simultaneously, water content after oil filters is minimum can only to reach about 20 milligrams/kilogram (ppm), though be significantly less than the index of steam turbine, can not reach the outstanding index 5 milligram/kilogram (ppm) of transformer with oil with oil 100 milligrams/kilogram (ppm).

Summary of the invention:

Technical problem to be solved in the utility model is:

Provide a kind of and dewater, pernicious gas is thorough, high-efficiency turbulent flow simple in structure is urged the phase transformation oily-water seperating equipment.

The technical solution of the utility model is as follows:

Be provided with nozzle on the center line in the import of tubular turbulent flow generator, be provided with tubaeform anemostat in turbulent flow generator, the wide-mouth of anemostat is facing to the outlet of turbulent flow generator, and the thin mouth of anemostat is facing to the nozzle of turbulent flow generator.

The beneficial effects of the utility model are:

Not only can handle emulsified water, and handle little water works very well, make oily water content after the processing less than 5 milligrams/kilogram (ppm).

Fig. 1 is the overall structure figure of vapour-liquid two-phase turbulent flow oily-water seperating equipment;

Fig. 2 is the overall structure figure of the utility model device;

Fig. 3 is a turbulent flow generator structure chart of the present utility model;

Fig. 4 is a carbonated drink separator box structure chart of the present utility model;

Fig. 5 is that figure cuts open in the oily vapour separating plate of the present utility model office of overlooking.

Wherein: 1 fore pump, 2 one-level filter screens, 3 heaters, 4 high-pressure pumps, 5 secondary filter screens, 6 turbulent flow generators, 7 carbonated drink separator boxs, 8 oil drain pumps.61 nozzles, 62 anemostats; 71 carbonated drink separator box shells, 72 vapor openings, 73 apopores, 74 oil outlets, 75 vapour collect covers, 76 sieve apertures, 77 oil pipes, 78 oily vapour separating plates.

The specific embodiment:

Behind the oil circuit of secondary filter screen, be connected to turbulent flow generator, two or more turbulent flow generator serial connections are used the better effects if of turbulent flow, the outlet of turbulent flow generator feeds the oil pipe of the oily vapour separating plate of carbonated drink separator box, and oily vapour separating plate base plate is a waveform, and upper plate is a sieve plate.When deep fat passes through turbulent flow generator, the W/O vaporization, formation oil, vapour mixture enter the carbonated drink separator box, oil, vapour mixture obtain oily vapour by oily vapour separating plate to be separated, the gas that do not condense is discharged by vapor opening, condensing water vapor flows out by apopore along inner cover is dirty after forming water, and oil enters in the circulating oil path by the oil outlet outflow of vapour collect cover bottom.

The main air that the utility model has removed the short phase transformation oily-water seperating equipment of high-efficiency turbulent flow is equipped with orifice plate and secondary air outfit orifice plate, though there is not the introducing of air, but the same two-phase flow that forms of water vapour body that the one-level turbulent flow generator is separated out and oil stream, to produce inflate compression pulsation circulation in outlet of one-level turbulent flow generator and secondary turbulent flow generator place, the contact area of vapour, liquid is increased, the easier escape of water in the liquid comes out to form water vapour, and the pernicious gas in the transformer oil is separated out thereupon simultaneously.

Claims (1)

1, the short phase transformation oily-water seperating equipment of a kind of high-efficiency turbulent flow, form by fore pump, one-level filter screen, heater, high-pressure pump, secondary filter screen, oil drain pump, carbonated drink separator box, it is characterized in that: be provided with nozzle on the center line in the import of tubular turbulent flow generator, in turbulent flow generator, be provided with tubaeform anemostat, the wide-mouth of anemostat is facing to the outlet of turbulent flow generator, and the thin mouth of anemostat is facing to the nozzle of turbulent flow generator.
