Abstract
The utility model provides a kind of knot screen of liquefied natural gas, belongs to liquefied natural gas purification technique field.Its structure includes the first manifold (9) and the second manifold (10) is spirally wound on core (11), and first manifold (9) and the second manifold (10) respectively have two inlet manifold and outlet manifold.First inlet channel (6), convection current exhaust duct (7) and the second air intake duct (8) are arranged on base (3), described that flow inlet port (4) and outlet passageway (5) are arranged on radome fairing (1).The pressure-air entered from manifold convection current air inlet pipe takes away impurity air-flow to blowing, purified gas after processing is discharged from the other end of membrane channels, almost without the pressure loss, film is dutiful from not needing circulating liquid, therefore also with regard to No leakage and blowdown problem, environment will not be polluted and is not easy to be influenceed by external environment condition.
Description
Technical field
The utility model is related to liquefied natural gas purification technique field, the removal of impurities dress of specifically a kind of liquefied natural gas
Put.
Background technology
Membrane separation technique originated from for 19 end of the centurys, on the basis of many liquid-liquid separation technologies, by further hair
Exhibition, so that as the current new technology that natural gas is handled suitable for industrially scalableization.In gas industry, using UF membrane
Method carbon dioxide removal and hydrogen sulfide have become the strong rival of the techniques such as conventional amine, Physical Absorption and glycol dehydration,
Its main cause is, it have construction investment and operating cost it is low, simple to operate, without running device, floor space be small and weight
Light many advantages, such as.
Utility model content
Technical assignment of the present utility model is to solve the deficiencies in the prior art to fill there is provided a kind of removal of impurities of liquefied natural gas
Put.
The utility model solves the technical scheme that its technical problem used：
The operation principle of the design is, filter membrane does not have a hole as filter medium, the separation of gas be according to
It is dissolved in by some gas components in film and spreads this principle through solid material and is completed.There is speed during due to air penetrating film
Difference, it is achieved that two kinds of gas is separated into possibility.According to the difference of separation condition, the speed ratio of the polymer of carbon dioxide
Methane is higher by 15-40 times.
In the processing of typical sulfur-containing gas, the pressure limit of feeding gas is generally 4.14-13.8MPa, and passes through stream
Outer output pressure be then less than 69Kpa, methane stays in high-pressure side, almost without the pressure loss.
A kind of knot screen of liquefied natural gas, a kind of knot screen of liquefied natural gas, first manifold (9) and
Two manifolds (10) are spirally wound on core (11), and first manifold (9) and the second manifold (10) respectively have two inlet manifold
And outlet manifold.First inlet channel (6), convection current exhaust duct (7) and the second air intake duct (8) are arranged on base (3), institute
State and flow inlet port (4) and outlet passageway (5) are arranged on radome fairing (1).The base (3) and the radome fairing (1) are installed
At housing (2) two ends.
The utility model prior art compares produced beneficial effect：
1) the design using film be dutiful from, during work do not need circulating liquid cooled down, in the mistake of separation
No longer changed in journey after liquid natural gas gasification to liquid phase, than therefore also being asked in traditional condensation with regard to No leakage and blowdown
Topic, will not pollute to environment and be not easy to be influenceed by external environment condition.
2) solvent need not be additionally added when working, using the pressure of natural gas in itself as motive force, and natural gas
The pressure of itself does not almost lose.
3) the first manifold and the second manifold spiral winding, increase the path of natural gas flow, improve purification efficiency, together
When, natural gas flow-type in manifold can roll due to ceaselessly converting direction of advance, and then produce flow-disturbing, improve
The uniformity coefficient of purification.

Embodiment
Embodiment of the present utility model is illustrated with reference to accompanying drawing.
A kind of knot screen of liquefied natural gas, a kind of knot screen of liquefied natural gas, first manifold (9) and
Two manifolds (10) are spirally wound on core (11), and first manifold (9) and the second manifold (10) respectively have two inlet manifold
And outlet manifold.First inlet channel (6), convection current exhaust duct (7) and the second air intake duct (8) are arranged on base (3), institute
State and flow inlet port (4) and outlet passageway (5) are arranged on radome fairing (1).The base (3) and the radome fairing (1) are installed
At housing (2) two ends.
Further, outlet passageway is sealed stainless steel lathe dog joint.
Further, to the sealed stainless steel lathe dog joint of flow inlet port.
Further, the first inlet channel, the second air intake duct use sealed stainless steel lathe dog joint.
Further, convection current exhaust duct uses sealed stainless steel lathe dog joint.
During work, unstrpped gas enters film core one end, and the duct between being sealed then along film is flowed, when unstripped gas is along film table
Surface current is out-of-date, and certain pore fillers can promote gas stirring, and the gas component of easy permeability passes through film, seals middle into film, Ran Houyan
Helical duct to enter in steel pipe, form one transmission air-flow for supporting low pressure, the purified gas after processing is arranged from the other end of film core
Go out, almost without the pressure loss.The purity of purified gas depends on the quantity of series connection film core, can if the gas flow of processing is big
Film device is used in parallel.
It should be noted that above content is only illustrating the technical solution of the utility model, rather than to the utility model
The limitation of protection domain, although the embodiment part is explained to the utility model, this area it is common
It will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this reality
With the spirit and scope of new technique scheme.
