Technical field
One kind be the utility model is related to from ejection circulation backflow supersonic cyclone separator, belong to supersonic condensing separation dress
Technical field is put, is widely used in that natural gas, coal bed gas, shale gas and tight gas etc. are aqueous, hydrocarbon-containifirst gas are dehydrated, take off
Hydrocarbon.
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
Rate and operating flexibility scope etc. still suffer from some limitations.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 form（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 established 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 when destroying 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）Although the shortcomings that overcoming eddy flow postposition type separator, because fluid is entering
Just have begun to rotate before entering 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 with the continuous change of operating parameter, swashing for this device can be caused
Ripple occur position scope constantly change, very big probability can enter jet pipe in, can to service behaviour produce dramatic impact.This

The ring-type discharge opeing interstitial structure that pipe is formed, reach the purpose for excluding condensed liquid., it is necessary to increase in the case of condensation output of fluid is excessive
It when adding the size of this annular space, can cause to produce shock wave in supersonic speed la farr pipe diffuser, cause static temperature in jet pipe to raise,
Condensed liquid evaporates, larger so as 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 discharge opeing
The moisture of intracavitary carries out repeatedly circulation so as to the dry gas for the liquid that is removed, but the device is using 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, and it is relatively low not to be suitable for inlet pressure
Operating mode.There is also the defects of double throat self-starting ultrasonic cyclone separators similar drip ring gap structure for the equipment simultaneously.
Therefore, it is necessary to develop a kind of new supersonic speed separation equipment for overcoming drawbacks described above.
