Description
Technical field
The present invention relates to natural gas transportation field, particularly relate to a kind of rock gas knock out drum.
Background technique
Many natural gas facilities and corresponding facility are all equipped with rock gas buffer area (being usually also knock out drum), and they can be used for regulating different load conditions.The present invention is mainly used to the rock gas buffer capacity improving buffer area.
LNG Liquefied natural gas truck is equipped with rock gas knock out drum usually, and it can adjust according to acceleration or no-load running state.Also similar situation is there is in other the natural gas facility such as compressed natural gas gas station, LNG Liquefied natural gas terminal, the compressed natural gas gas station of a such as standard can use four-stage compressor to seal rock gas, the knock out drum of 4 ~ 5 different sizes compressor can be equipped with simultaneously in order to adapt to different load operating condition.All knock out drums are all standard types, form primarily of pneumatics force container.As a rule, the volume reducing knock out drum (or buffer area) is absolutely necessary.But existing buffer area can cause energy loss, and also there is certain potential safety hazard simultaneously.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of rock gas knock out drum, large and there is the problem of certain potential safety hazard for solving existing rock gas damping device energy loss.
For achieving the above object and other relevant objects, the invention provides following technological scheme:
A kind of rock gas knock out drum, comprise the pressurized container that has enclosed construction, described pressurized container offers suction port and air outlet, methane adsorption device is placed with in described pressurized container, wherein, described methane adsorption device comprises a filtering container and methane adsorbent, and described methane adsorbent is positioned in described filtering container closedly.
Preferably, described filtering container is porous flexible sealing package.
Preferably, described porous flexible sealing package is by spinning cloth or nonwovens is made.
Preferably, described methane adsorbent is by the combination of one or more in active carbon, carbon black, zeolite, Activated Graphite, molecular sieve.
As mentioned above, the present invention has following beneficial effect: by adding the LNG Liquefied natural gas such as zeolite or active carbon sorbent in LNG Liquefied natural gas buffer area, under lower pressure (lower than 35bar), the buffer capacity of LNG Liquefied natural gas can significantly be increased, for identical buffer capacity, Adsorption Natural Gas buffer area can be less than ordinary buffer district a lot of times under normal circumstances.
LNG Liquefied natural gas buffer area or knock out drum effectively can improve the methane content storing or cushion, and the function of this storage and buffering is by using the methane adsorbent of active carbon, molecular sieve, zeolite, Activated Graphite equimolecular level to realize.This buffer area or storage device can be applied in liquefied natural gas facility, haulage vehicle and compressed natural gas depot, to reduce by the energy loss efficiency of 5%.LNG Liquefied natural gas dashpot involved in this invention can effectively adsorbed gas, falls the oligosaprobic various harm simultaneously reducing the unknown.
