Description
Technical field
The utility model relates to a kind of natural gas preswirl supersonic speed cyclone separator.
Background technology
Gas industry dewatering commonly used has expansion cooling method, pressurization cooling method, solid absorbent method, solvent absorption etc.For bigger device, equipment investment and operating cost are all than higher.The dehydration of natural gas ultrasonic eddy flow is a kind of novel dehydration technique, is an emerging technology in gas dehydration field.It utilizes the steam condensation of natural gas under the supersonic speed state to carry out gas dehydration, on thermodynamic principles and system's formation, with the traditional natural gas dewatering significant difference is arranged.Natural gas ultrasonic dehydration focuses on the function of decompressor, separator and compressor in the pipeline, have simple and compact for structure, no-rotary part, reliability is high, no chemical processing system, the low investment and advantage such as maintenance cost.The operation principle of the technology of stating all is to utilize pressure to accelerate to supersonic speed step-down cooling through De Laval noz(zle) to produce condensation in the patent both at home and abroad, produces high-speed eddy and before or after quickening, be provided with vortex generator.The cryogen of rotation makes the liquid that produces that condenses be attached to tube wall under action of centrifugal force at a high speed, and gas is realized gas-liquid separation then in the pipeline center position through the gas, liquid collecting pipe of different tube diameters.Gas phase part is outer failing after diffuser pipe partly recovers pressure.These technology all do not have to consider to alleviate the liquid phase separation load, and aqueous water and sand are to the influence of the erosive wear of supersonic speed cyclone separator runner.In addition, a large amount of liquid phase waters flow into Laval nozzle, and circulation area reduces, and make the separator service behaviour unstable.
The utility model content
The purpose of the utility model is to provide a kind of preswirl supersonic speed cyclone separator, sloughs original liquid phase component and solid granulates in the natural gas, to alleviate the load of supersonic speed cyclone separator, strengthens the job stability of complete machine, improves its separating property.
The described preswirl supersonic speed of the utility model cyclone separator by a center cone be positioned at that a shell constitutes the preswirl device respectively, the shrink nozzle of prewhirling, the disengagement chamber of prewhirling, cyclone, Laval nozzle, separator, diffuser and diffusion support collector ring and form; The coaxial installation of center cone and shell forms a ring cavity; The preswirl device is positioned at front end gas inlet place, and center cone surface circumferential arrangement has curved blade, and established angle matees with coming flow path direction; Connect cyclone and preswirl device by the flaring shrink nozzle of prewhirling, the disengagement chamber of prewhirling is positioned at outside the cyclone, is communicated with by the groove that is provided with on the cyclone shell; Prewhirl disengagement chamber below is free liquid phase and solid particle outlet; Cyclone center cone surface circumferential arrangement has curved blade, and established angle matees with coming flow path direction; Flaring Laval nozzle entrance connects cyclone and Laval nozzle straight length, and the Laval nozzle straight length is connected with disengagement chamber through tubaeform separator; Diffuser is arranged in disengagement chamber, and an end is the wedge taper, is complementary with the tubaeform shape of separator, and separator is inserted in taper, and its outer wall forms the circular passage with the separator inwall and is communicated with disengagement chamber; The straight center cone of Laval nozzle straight length is connected with the conical centre's awl that is positioned at diffuser; The outer wall and the diffuser inwall of conical centre's awl form the circular passage; Support collector ring and be positioned at diffuser, the end of conical centre's awl is communicated with the dry gas outlet by being arranged on the centre bore that supports collector ring; The moisture outlet is arranged on the disengagement chamber bottom.
Its operation principle is following; Under the well head pressure condition, flow into the preswirl device from the natural gas of underground extraction; Produce strong eddy flow through the curved blade water conservancy diversion, band revolves the gas shrink nozzle of prewhirling of flowing through, according to the conservation of angular momentum; Centrifugal acceleration increases along with reducing of radius of turn, and free liquid phase and solid particle flow out with air-flow under powerful action of centrifugal force.Revolve gas flow through blade angle and the cyclone that flows to coupling through the band that takes off liquid phase water and solid particle, the swirl strength of air-flow is enhanced again; Through Laval nozzle, adiabatic expansion is to supersonic speed, and gas internal energy reduces simultaneously, and kinetic energy increases, and forms low-temp low-pressure.When temperature is reduced to when making the gas supersaturation, the water vapour in the natural gas just is condensed out, and powerful centrifugal force makes it be collected at the ring cavity skin, and more the superior is attached on the outside wall surface.The taper burble point of diffuser is positioned at the Laval nozzle end, and it is two-layer inside and outside air-flow is divided into.Air-flow begins to recover through one shock pressure, and shock-wave spot changes with the difference of blow down ratio.Outer wet gas current flows out from the moisture outlet through separator ring cavity, disengagement chamber; The internal layer dry gas stream flows out from the dry gas outlet through the diffuser ring cavity.Natural gas through the diffusion separator obtains recompression.
The natural gas that contains liquid phase component and solid granulates is carried out pre-separation handle, the natural gas after pre-separation is handled only contains gaseous component, to alleviate the load of supersonic speed cyclonic separation section, strengthens the job stability of complete machine, improves its separating property.
