Description
Technical field
The utility model relates to natural gas transportation field, particularly relates to a kind of natural gas output channel with buffer gear.
Background technology
Many natural gas facilities and corresponding facility are all equipped with natural gas buffering area (being conventionally also surge tank), and they can be usedRegulate different load conditions. The utility model is mainly used to improve the natural gas buffer capacity of buffering area.
Liquefied natural gas truck is equipped with natural gas surge tank conventionally, and it can be adjusted according to acceleration or no-load running state.In other the natural gas facility such as compressed natural gas gas station, liquefied natural gas terminal, also exist similar situation, such as oneThe compressed natural gas gas station of individual standard can seal natural gas with four-stage compressor, simultaneously in order to adapt to different loaded work piecesCondition, can be equipped with 4～5 different big or small surge tanks on compressor. All surge tanks are all standard types, mainly by skyPressure vessel composition. As a rule, the volume that reduces surge tank (or buffering area) is absolutely necessary. But existingBuffering area can cause energy loss, and also has certain potential safety hazard simultaneously.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of natural gas with buffer gearOutput channel is large and have a problem of certain potential safety hazard for solving existing natural gas buffer unit energy loss.
For achieving the above object and other relevant objects, the utility model provides following technical scheme:
There is a natural gas output channel for buffer gear, comprise that one is suitable for exporting the carrier pipe of natural gas, at this carrier pipeOn transport path, be provided with a buffer gear, this buffer gear comprises that one has pressure appearance hermetically-sealed construction and that be communicated with carrier pipeDevice and the absorbed natural gas adsorbent of confession, offer the air inlet and the gas outlet that are suitable for connecting conveying pipe, adsorbent on pressure vesselBe wrapped in a porous flexible sealing bag, and be communicated with this porous flexible sealing bag and be jointly positioned in pressure vessel.
Preferably, described adsorbent is methane adsorbent.
Preferably, described methane adsorbent is one or more in active carbon, carbon black, zeolite, Activated Graphite, molecular sieveCombination.
Preferably, described porous flexible sealing bag is by spinning cloth or nonwoven is made.
Preferably, between the inwall of described pressure vessel and porous flexible sealing bag, be provided with air baffle.
Preferably, at air inlet and gas outlet place, one filtering container is respectively set.
As mentioned above, the utlity model has following beneficial effect: the utility model is slow by arranging in natural gas transmission pipelinePunch mechanism adds the liquefied natural gas such as zeolite or active carbon adsorbent in buffer gear, under low pressure condition (lower than 35bar),The buffer capacity of liquefied natural gas can significantly be increased, for identical buffer capacity, under normal circumstances Adsorption Natural GasBuffering area can be less a lot of times than ordinary buffer district.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can be by this descriptionDisclosed content is understood other advantages of the present utility model and effect easily.
Refer to Fig. 1. Notice, appended graphic the illustrated structure of this description, ratio, size etc., all only say in order to coordinateThe content that bright book discloses, understands and reads for person skilled in the art scholar, not enforceable in order to limit the utility modelQualifications, thus the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size,Do not affect under effect that the utility model can produce and the object that can reach, all should still drop on the skill that the utility model disclosesArt content obtains in the scope that can contain. Meanwhile, in this description, quote as " on ", D score, " left side ", " right side ", " centre "And the term of " " etc., also only for ease of the understanding of narration, but not in order to limit the enforceable scope of the utility model, it is relativeThe change of relation or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
Referring to Fig. 1, is a kind of schematic diagram of the natural gas output channel with buffer gear, and as shown in the figure, this has bufferingThe natural gas output channel of mechanism comprises that one is suitable for exporting the carrier pipe 2 of natural gas, on the transport path of this carrier pipe 2, arrangesHave a buffer gear, this buffer gear comprises that one has pressure vessel 1 hermetically-sealed construction and that be communicated with carrier pipe 2 and supplies absorptionThe adsorbent 3 of natural gas, offers the air inlet 11 and the gas outlet 12 that are suitable for connecting conveying pipe 2, adsorbent on pressure vessel 13 are wrapped in a porous flexible sealing bag 4, and are communicated with this porous flexible sealing bag 4 and are jointly positioned in pressure vessel 1.
In concrete enforcement, described porous flexible sealing bag 4 is by spinning cloth or nonwoven is made.
In concrete enforcement, described adsorbent 3 can be methane adsorbent 3, wherein, methane adsorbent 3 can by active carbon,The combination of one or more in carbon black, zeolite, Activated Graphite, molecular sieve.
In concrete enforcement, pressure vessel 1 is interior can arrange multiple porous flexible sealing bags 4 having, can be at pressure vessel 1Inwall and porous flexible sealing bag 4 between air baffle is set, for facilitate natural device flow, reduce potential safety hazard simultaneously.In addition, can also one filtering container 5 be respectively set at air inlet and gas outlet place, for filtering the impurity of natural gas, place intoGas port and gas outlet place porous flexible sealing bag 4 accumulated impurities, cause buffering effect to reduce.
In sum, the utility model, by buffer gear being set in natural gas transmission pipeline, adds zeolite in buffer gearOr the liquefied natural gas adsorbent such as active carbon, under low pressure condition (lower than 35bar), the buffer capacity of liquefied natural gas can obtainTo significantly increasing, for identical buffer capacity, Adsorption Natural Gas buffering area can be little more a lot of than ordinary buffer district under normal circumstancesDoubly.
In addition, can also effectively improve storage or buffering methane content, the function of this storage and buffering be by use active carbon,The methane adsorbent of point sub level such as molecular sieve, zeolite, Activated Graphite is realized. Buffer gear in the utility model is all rightThe oligosaprobic unknown various harm that simultaneously reduce, fall in effectively adsorbed gas. So the utility model has effectively overcome existing skillVarious shortcoming in art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model. AnyPerson skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable is not departing under the spirit and technological thought that the utility model disclosesAll equivalences that complete are modified or change, and must be contained by claim of the present utility model.
