Abstract
The utility model discloses an assorted spherical steam-water extractor for enhancing the steam dryness for the thermal recovery steam injecting boiler in the oilfield, comprising a casing and an internal extracting device. The casing is spherical; a plurality of cyclone extractors are arranged in the casing; the side surface of each cyclone extractor is provided with a pipe barrel for inputting the steam; the inlet of the pipe barrel is communicated with a steam pipe line communicated with the outside of the casing; a valve is arranged on the steam pipe line. The cyclone extractor is a very effective steam-water extractor with the extraction efficiency of one time as high as 99% more or less, which completely satisfies the requirement of the dryness of the injected steam in the thermal power recovery, and better exerts the effect of the thermal power recovery.
Description
One, technical field
The utility model relates to a kind of supporting special device of oil thermal recovery steam boiler raising steam quality that is.
Two, background technique
Along with deepening continuously of thickened oil recovery, the growing needs of thickened oil recovery new technology can not have been satisfied with the method for conventional boiler (80% steam quality) steam injection.Show that according to newest research results the steam quality effect that the high round exploitation in viscous crude later stage must be injected more than 95% is just better.And at present at the steam boiler of usefulness, owing to be subjected to the restriction of its water-treating equipment, its highest steam quality is 80%, and only is about 70% during actual motion, and this has had a strong impact on the performance of heating exploitation effect.
The carbonated drink separation equipment is applied to steam boiler has had the history of more than ten years, but for various reasons, equipment is difficult to adapt to each oil field complex geological conditions, causes defectives such as its separation effect is low, operating conditions is unstable, noise is big, makes equipment not give full play to due effect.
Three, summary of the invention
The purpose of this utility model provides a kind of spherical steam-water separator, and its good separating effect can improve steam quality significantly.Spherical steam-water separator is made of housing and inner segregating unit thereof, housing is spherical, is provided with a plurality of cyclone separators in the spherical shell, and there is the socket of input steam the side of each cyclone separator, the socket inlet is communicated with the steam pipe line that leads to outside, and valve is arranged on the steam pipe line.
The separation process of two-phase fluid is quite complicated, realizes by the comprehensive effect of several centrifugations often.Cyclone separator combines centrifugation, gravity separation and membrane type centrifugation and carries out carbonated drink separation.Tangentially introduce the cylindrical shell of cyclone separator by the next steam water interface of boiler export with very big kinetic energy, it is changed into by straight line motion rotatablely moves, form centrifugal force (force of gravity is big 17.9～47.5 times), because vapour and water exist severe poor, vapour spiral in the whirlwind tube rises, form water column, water then throws to barrel and rotation descends, and forms parabolic in tube; Also have small quantity of water droplets to be brought into the air space at whirlwind tube middle part by steam flow, these water droplets are pushed to wall gradually in the process that rises with the steam flow rotation.When the venetian blind corrugated sheet top cap of steam by whirlwind tube top, separate making steam further separated again by membrane type, water then imports the water space reposefully by the guide vane of bottom in annulus.
Cyclone separator in the housing is a kind of very effective water separator, and its separation effect has satisfied the mass dryness fraction requirement that heating exploitation injects steam fully up to about 99%, can bring into play the effect of heating exploitation preferably.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment
The utility model calculates through the check to various parameters, under the prerequisite that obtains the maximum separation space according to the characteristics of oil field service condition (pressure and flow shakiness).Be optimized design, selected spherical shell 1, four independently cyclone separators 2 are set in the housing, can increase and decrease the open and close quantity of cyclone separator according to load condition.For making the flow that enters each cyclone separator even, outside housing, be provided with distributor 10, distributor 10 is the distribution tank bodies that are connected with a plurality of pipelines, and its each output tube is communicated with a cyclone separator, and the steam inlet pipe of each cyclone separator all connects main steam range through distributor.For further fine liquid particles in the steam being separated, steam outlet is provided with the secondary separation element on cyclone separator top---horizontal venetian blind corrugated sheet separator 4, louver separator 4 is common components of present water separator, the venetian blind corrugated sheet of horizontal positioned imports to separately the pipeline of drawing respectively with water and steam, introduction pipe through being arranged on vapour, water space is continuously drawn vapour, water, reaches the purpose with vapour, water separation at last.For measuring steam quality, be provided with saturated vapour sampler 5 at steam outlet.Because stove water salinity is very big, for preventing isolated stove water generates foam to influence separation effect, the place is provided with drainage device 6 especially at the stove water out.At the cyclone inlet place for preventing vapour, the inhomogeneous separating effect that influences of water flow velocity, be provided with equal steam vent plate 7, all steam vent plate 7 is flat boards of a porous, its plane and vapour, water travel direction are vertical, vapour, current are during by equal steam vent plate 7, it is admixed together again to be divided into a plurality of equal portions, so can enter into separator equably by flow velocity.For monitoring that liquid level is provided with double colored indicator 8, be provided with Liquid level adjusting valve 9 for regulating liquid level.For follow-up work pressure is provided with pressure gauge 3, for sample examination is provided with sample cooler 11.For preventing that the current rotation from causing the water level deflection, one cruciform baffles agitated vessel is installed to eliminate rotatablely moving of current in the housing at housing bottom, the cross baffle plate is the riser of the criss-crossing of horizontal positioned, when current when tank base forms vortex, stopped by the cross baffle plate and weaken elimination.
Steam-water separator is provided with a safety valve on apparatus body, prevent boiler superpressure in running, carries out self-protection.Boiler is realized interlocking control automatically with steam-water separator on control system.
The liquid level of equipment is the accumulation of the difference of influx and discharge just.The stable balance that just will control influx and discharge that keeps liquid level remains in the highest and the nil-norm scope amount of savings.The characteristic of liquid level is a single order, does not have unstable problem so liquid level is regulated.
System adopts the single loop ratio to regulate the quality of regulation that satisfies liquid level.Adjustment process is: at first the electrical signal that liquid level in the separator converts standard to is compared 4 by once showing (differential pressure transmitter)---20mm A.Mathematic(al) representation: Io=4+Hx/H (20-4) sends into regulator and given signal by behind the scale operation of regulator, and corresponding one outputs signal to modulating valve, valve is on the position of some apertures.When liquid level (Hx) when changing corresponding again one of regulator export to modulating valve, valve is on the position of another aperture, the size of flow is opened and is changed along with modulating valve, finally reaches to keep the stable of liquid level.The variation of liquid level and height directly and are indirectly observed by level meter and secondary meter (regulator).
In order to prevent that liquid level that fortuitous event causes from transfiniting or to spend the low carbonated drink separation that influence, set up the indication of reporting to the police of the high lower bound of liquid level, operator can in time be handled, guarantee stablizing of liquid level.
