Description
Technical field
The utility model relates to natural gas storage and transportation fields, and in particular to a kind of gas pipeline dehumidification device.
Background technique
Natural gas is of great significance to the adjustment of China's energy resource structure as clean fuel, whole year in 2015, China
Natural Gas Consumption Using is more than 1900 × 108m3, the accounting in primary energy structure reaches 5.8%, and global natural gas is primary
Accounting in energy resource structure is 24%, so the following China's natural gas potential of demand is huge.In this context, the long defeated pipe of natural gas
The safe operation in road is most important.Natural gas is in the natural gas conveyed by gas pipeline due to the stream of the various aspects of acquisition
Journey so that a certain amount of moisture can be carried in gas, in gas pipeline due to high flow rate, cryogenic high pressure, fluid agitation etc. because
The influence of element, easily generation gas hydrates.This can not only reduce gas flow area, cause to impact to pipeline valve, very
Cause pipeline burst to can also block valve, seriously threaten the operation security of gas pipeline, so the dehumidifying for gas pipeline
Drying is particularly important.
In the dehumidification device used, generally to have the drawback that structure is complicated bulky, maintenance cost is high, is difficult at present
Various environment are adapted to, therefore in view of the above-mentioned problems, it is very necessary for designing the adaptable gas pipeline dehumidification device of one kind.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of gas pipeline dehumidification device, the utility model devices
Structure is simple, maintenance cost is low, replacement easy to disassemble is used for multiple times, and can be applied to well site or the offshore platform of various environment, removes
Wet effect is good, and large-scale promotion is suitble to use.
The utility model embodiment provides a kind of gas pipeline dehumidification device, which is characterized in that utility model device packet
Include crust of the device, air inlet hole wall, filter screen, sealing cover, pressure relief opening, relief valve, air inlet connection valve, air inlet switch, pressure
Sensor, gas outlet switch, gas outlet connection valve, watch window, filter screen are located at air inlet pars intramuralis and form annular compartment,
Air inlet hole wall inner wall is connected with pressure sensor, air inlet switch, air inlet connection valve, and air inlet hole wall outer wall is opened with gas outlet
Pass, gas outlet connection valve are connected, and sealing cover is located at below air inlet hole wall, and pressure relief opening, relief valve are located above air inlet hole wall, institute
It states watch window and is located at crust of the device surface.
A kind of gas pipeline dehumidification device beneficial effect of the utility model embodiment is: 1) utility model device uses
It is convenient, it is low in cost, it is suitable for large-scale promotion；2) the utility model apparatus structure is simple, maintenance cost is low, easy to disassemble repeatedly makes
With can be applied to well site or the offshore platform of various environment；3) utility model device can be by observing pressure sensor numerical value
Or it is directly observed by watch window, it is known that impurity content in filter screen, in order to replace in time.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
