Description
Technical field
Purifying and separating device for eddy gas of the present invention belongs to thermal technology's energy saver, mainly is the gas that is transported to before the pipe-line system is carried out isolation of purified.
Background technology
For moisture and the heavy component liquid that prevents natural gas in pipeline is carried causes corrosion or erosion to facilities such as compressor and pipelines, prevent to stop up, must before entering pipe-line system, these harmful moisture and heavy components in the natural gas be separated because of the critical component of separating out in the induction systems such as causing valve of solid matter (as ice).So treatment technologies such as gas water separation are the hot issues that people study always.
At present, Chang Yong separation or the treatment technology that removes wet gas mainly contain: chemisorbed-method of reproduction, physical absorption--method of reproduction, adiabatic throttling method, mechanical refrigeration method and turbine expander refrigeration method etc.These conventional methods have a series of advantage, and are big as good separating effect, the dehumidifying degree of depth, can reach lower dew-point temperature etc., so these conventional methods have all obtained should having widely to a certain extent.But also there are many shortcomings in these methods,, construction investment huge as facility greatly, want the more merit of consumption rate, and also can cause to a certain degree pollution to environment.
Fig. 9 is the udex process dehumidifying of generally adopting at present, the process flow diagram of purified natural gas both at home and abroad: wet gas at first enters unstripped gas separator 23, isolate free fluid and solid impurity, gas after the separation enters that glycol solution is reverse in absorption tower 24 and the tower contacts, steam in the gas is absorbed by glycol solution, the dry gas that leaves absorption tower 24 is through gas/poor glycol heat exchanger (poor glycol cooler) 25, enter the glycol solution (poor glycol) on absorption tower with cooling, then, entering pipeline fails outward.
After poor glycol behind process gas/poor glycol heat exchanger 25 enters absorption tower 24, the steam that absorbs in the wet gas becomes rich glycol, then, from absorption tower 24, flow out, enter flash tank 28 again with after good hot glycol lean solution (the hot poor glycol) heat exchange of regeneration, separate through low pressure flash, isolate the hydrocarbon gas that is absorbed by glycol solution.
The rich glycol of discharging from flash tank 28 passes through solid filter (fabric filter) 29 and active carbon filter 30 successively, removes small amount of solid, hydro carbons chemical agent and other impurity that glycol solution absorbs in the absorption tower and carries.
The rich glycol of being come by solid filter (fabric filter) 29 and active carbon filter 30 enters regenerator 26 through after poor/rich glycol heat exchanger 31 preheatings, and the steam in the rich glycol is removed, and becoming concentration is the above poor glycol of 99% (ω).
The poor glycol that is come out by regenerator 26 is introduced into surge tank 27, and the poor/rich glycol heat exchanger 31 of flowing through again cools off, and recycles by entering absorption tower 24 after glycol pump 32 pressurizations then.
By above flow process as can be seen, the regenerative system in udex process dehumidifying, the purified natural gas system is very complicated, and this will certainly increase investment of equipment, and the operation and maintenance cost of equipment is raise, and operation is also inconvenient, and floor space increases; In addition, at sea therefore platform, should not use udex process to handle natural gas because the heaving of the sea meeting influences glycol solution proper flow in the absorption tower; Glycol contaminated or decompose after have corrosivity, can corrosion pipeline etc. equipment.
Summary of the invention
The objective of the invention is to overcome prior art and structural deficiency, the purifying and separating device for eddy gas of developing a kind of simple in structure, easy to operate, environmental friendliness, integrated cost is low and has the works fine performance.
Technical scheme of the present invention is referring to Fig. 1, the present invention is provided with gas and separates and gas purification portion branch, be characterised in that it includes the De Laval noz(zle) 1 that is used for gas speedup, heat sink, be used for the cyclone 2 that gas purification separates, and the separator tube 3 that is connected with cyclone 2, the diffuser pipe 4 that is used for gas boosting and deceleration reaches the cyclone housing 5 that De Laval noz(zle) 1 is connected with cyclone 2, the diffuser pipe housing 6 that is connected with separator tube 3; The mid portion of apparatus structure is cyclone 2 and separator tube 3, cyclone 2 inserts the inner chamber of the cyclone housing 5 that links to each other with an end of De Laval noz(zle) 1, the other end of De Laval noz(zle) 1 is natural gas gas feed 10, separator tube 3 is communicated with diffuser pipe 4, an annular channel 14 is arranged between separator tube 3 and the diffuser pipe 4, the other end of diffuser pipe 4 is dry gas outlet 11, and the bottom of diffuser pipe housing 6 is provided with the liquid outlet 12 of separating liquid from gas, and liquid outlet 12 communicates with annular channel 14.
