The defects of certain, such as structure are complex, and processing has difficulty, simultaneously as it is complicated, shock-wave effect is easily produced,
Cause vapor and heavy constituent easily to occur double evaporation-cooling phenomenon after condensation, be decreased obviously the removal efficiency of water, heavy constituent.
The content of the invention
To solve problems of the prior art, the present invention proposes a kind of simple in construction, working stability for natural
The flaring cyclone-type supersonic nozzle of gas disposal, the technical scheme that it is specifically used are as follows：
The present invention proposes a kind of flaring cyclone-type supersonic nozzle, mainly including nozzle entry, jet pipe converging transition, jet pipe larynx
Portion, jet pipe divergent segment, nozzle exit, positioned at cyclone of jet pipe divergent segment etc..
Above-mentioned jet pipe converging transition using bicubic curve method design, this method cause flow field excessively naturally, vortex it is smaller, can
Uniform air flow is obtained in contraction section exit, its curvilinear equation meets：
In aforesaid equation, x is jet pipe axial distance；rcrFor nozzle throat section radius；R is any axial distance of jet pipe
Section radius at x；L is the tapered segment length of jet pipe；XmFor the relative coordinate of front and rear two sections of curve tie points.
The selection of above-mentioned nozzle throat diameter is limited by air flow rate, and nozzle throat diameter dimension uses actual gas
State BWRS equations are calculated, and throat's curvilinear motion can not be too fast, therefore select one section of circular arc as jet pipe converging transition and jet pipe
The rounding off of divergent segment.
Above-mentioned jet pipe divergent segment is designed using conical pipe, and the angle of flare is 1~10 degree, and it is uniform that guarantee flows through cyclone air-flow.
Above-mentioned cyclone is made up of 2~8 part-structure identical wind sectors, and the structure can be such that gas produces at a high speed
Eddy flow, huge centrifugal force gets rid of drop to supersonic nozzle wall caused by eddy flow.
Natural gas containing vapor, heavy hydrocarbon component enters supersonic nozzle expansion through gas access and accelerated, by throat
Supersonic speed is accelerated to afterwards, and in jet pipe in the environment of low-temp low-pressure, vapor and heavy hydrocarbon component therein congeal into drop, then flow
Cyclone through jet pipe divergent segment, realizes high-speed rotational under the conditions of supersonic speed, and huge centrifugal force caused by eddy flow gets rid of drop
To supersonic nozzle wall, it is separated or absorbs in subsequent handling, so as to realize the removing of natural gas reclaimed water and heavy hydrocarbon component.
Natural gas supersonic vortex separation system beneficial effect provided by the invention is：Revolved compared to complicated supersonic speed
Stream separator processing is very convenient, easily realizes water, the condensation of heavy hydrocarbon and cyclonic separation, while avoids shock-wave effect with condensing
The double evaporation-cooling phenomenon of drop, traditional supersonic speed separator can be replaced to realize being dehydrated, taking off the complicated technologies such as heavy hydrocarbon for natural gas.
