Description
Technical field
The present invention relates to one kind from ejection circulation backflow supersonic cyclone separator and its separation method, belong to Supersonic quickly cooling
Solidifying separator technical field.
Background technology
Supersonic speed separator has no-rotary part, high pressure resistant, low and reliable etc. without external impetus driving, cost
Advantage.There is very strong applicability in gas dehydration, de- heavy hydrocarbon and lighter hydrocarbons recovery field.At present, ultrasonic dehydration technology is in state
It is inside and outside all still in experiment and preliminary field application stage, although the example of existing business application, separate and imitate in supersonic speed
Some limitations are still suffered from terms of rate and operating flexibility scope.Supersonic speed separator mainly has U-shaped, eddy flow postposition type and eddy flow
The class of prefix type three.Garret etc. is the U-shaped supersonic speed separator of representative, and the device is by Laval jet pipes and a rectangular cross-section
U-shaped passage be connected constitute（US3528217）.The type device structure is excessively complicated, and part needs assistant electromagnetic field or note
Enter inhibitor to solve the problems, such as hydrate and frozen block.The Twister Mark I that Twister BV companies develop are the rotation of representative
Postpositional blade type supersonic speed separator is flowed, the eddy current model that the type equipment is set up is when increasing blade incidence, the interception effect of blade
Fruit and vortex are asymmetric.And when supersonic gas and swirl vane are collided, strong shock wave can be produced, this can cause very big
Energy loss, or even influence flow field, required low-temp low-pressure environment during destruction water vapour Spontaneous Condensation, so that condensing
Drop segregation section due to temperature, pressure rise occur secondary volatilization, ultimately result in larger and from efficiency the drop of the pressure loss
It is low.Before the 3S that the Twister Mark II and Translang companies that Twister BV companies develop develop is the eddy flow of representative
Put formula supersonic speed separator（US6372019）It is due to that fluid is entering although overcoming the shortcoming of eddy flow postposition type separator
Enter and rotation is just had begun to before jet pipe, though the intensity of rotation is high, when reaching gas-liquid separation outlet by jet pipe and straight length, rotation
Turn intensity to have declined, separation can be caused not thorough enough, and being continually changing with operating parameter, swashing for this device can be caused
Ripple occur position scope be continually changing, very big probability can enter jet pipe in, can to service behaviour produce dramatic impact.This
Outside, the type equipment still suffer from the problem of can not adapting to the inlet pressure condition being actually continually changing.In addition, Beijing Aviation navigates
A kind of pair of throat self-starting ultrasonic cyclone separator and its separation method of its university（CN102274805B）Using double venturi
The structure type of series connection, while passing through porous wall construction one diffusion of formation between diffuser contraction section and diffuser expansion segment
The adjustable pneumatic adjustment structure of device venturi actual internal area, is realized under diffuser contraction section and diffuser expansion segment differential pressure action
Pneumatic adjustability.But the discharge opeing gap of the supersonic speed separator of type equipment belt circulation uses outer radius set in difference
The ring-type discharge opeing interstitial structure that pipe is constituted, reaches the purpose for excluding condensed liquid., it is necessary to increase in the case of condensation output of fluid is excessive
Plus this annular space size when, can cause to produce shock wave in supersonic speed la farr pipe diffuser, cause in jet pipe static temperature to raise,
Condensed liquid evaporates, so that it is larger to cause the decline of separative efficiency, pressure loss of energy.So, on the annular space structure of discharge opeing is
State a defect of supersonic speed cyclonic separation equipment.Beijing University of Technology proposes a kind of moisture recycling supersonic speed gas-purification
Separator（CN 201534048 U）.The structure is using leakage fluid dram and the pressure difference in la farr pipe diffuser exit, by exhaust chamber
Interior moisture carries out repeatedly circulation so as to the dry gas for the liquid that is removed, but the device uses the rearmounted knot of cyclone
Structure, the supersonic airstream come out from jet pipe, which hits blade, can produce shock wave, and have larger crushing, not be suitable for inlet pressure relatively low
Operating mode.There is also the defect of the similar drip ring gap structure of double throat self-starting ultrasonic cyclone separators for the equipment simultaneously.
Therefore, it is necessary to develop a kind of new supersonic speed separation equipment for overcoming drawbacks described above.
