Abstract
The utility model relates to a natural gas supply system. The natural gas supply system comprises a movable plate and a gas supply system body fixed to the plate in a skid-mounted mode. The natural gas supply system comprises at least one low-temperature storage tank, a vaporizer and a pressure reduction system. The gas outlet of the low-temperature storage tank is connected with a gas inlet of the vaporizer through a pipeline. The gas outlet of the vaporizer is connected with the gas inlet of the pressure reduction system through a pipeline. The gas outlet of the pressure reduction system is connected with the gas inlet of a buffer tank through a pipeline. The gas outlet of the buffer tank is connected with a gas-consuming point through a pipeline. The plate and the gas supply system body are arranged into a set through the skid-mounted process and can freely move, and therefore the gas supply system can be conveniently transported to a required position, gas can be safely and stably supplied when the gas supply system is communicated with the gas-consuming point, a large amount of construction input and a large number of installation expenses can be saved, application and acceptance of pressure pipelines are saved, the construction cycle can be greatly shortened, and greater, faster, better and more economical results are achieved.
Description
Technical field
The utility model relates to a kind of natural gas supply system, belongs to pipeline air feed field.
Background technique
The use of China's industrial gas is to be all supplied as master with bottled gas before the nineties, and has started central gas supply for a long time abroad.So-called " central gas supply " is exactly according to the size of gas consumption or delivered to and used gas point by pipeline after decompression with refrigerated storage tank, or deliver to and use gas point through pipeline by decompression unit with Dewar vessel, this plenum system has been saved a large amount of freights and a dead lift expense, energy-saving safety is reliable, so obtain popularizing energetically, China also progressively promotes this plenum system after the nineties.
Summary of the invention
The utility model provides a kind of natural gas supply system.
For achieving the above object, the technical solution adopted in the utility model is: a kind of natural gas supply system, comprise one movably column and with the fixing air supply system of column skid, this system comprises refrigerated storage tank, vaporizer and the depressurized system of at least one, the air outlet of refrigerated storage tank is connected with the suction port of vaporizer by pipeline, the air outlet of vaporizer is connected with the suction port of depressurized system by pipeline, the air outlet of depressurized system is connected with the suction port of knock out drum by pipeline, and the air outlet of knock out drum is connected and used gas point by pipeline.
In technique scheme, column becomes one group with air supply system by the process Installation of skid, and can move freely, convenient by air supply system be transported to the position needing connect use gas point just can air feed, safety and stability, can save a large amount of construction input and mounting cost, saves the report of pressure piping and builds examination, can greatly shorten the construction period, be that polylith is economized well.
Further, on every segment pipe, be equipped with valve.Can control speed and the convenient usage degree that detects pipeline of air feed.
Further, the valve between the valve between vaporizer and depressurized system and depressurized system and knock out drum is one-way cock.Can effectively avoid the refluence of gas
Further, vaporizer is air-heating type gasifier.
Further, between refrigerated storage tank and vaporizer, be provided with purifier near that side of vaporizer.Impurity in can Purge gas, ensures the quality of gas.
Further, the air outlet of knock out drum, is provided with device for adding odor near point of admission side.The gas leakage situation that can effectively avoid the Rig up error between knock out drum and point of admission to cause.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Natural gas supply system of the present utility model, can move freely, and air feed safety and stability has been saved to build and dropped into and mounting cost, has also saved the construction period; Valve can effectively be controlled air feed speed, especially uses individual event valve, can effectively avoid the refluence of gas; Purifier can effectively be removed the impurity in gas, ensures purity and the quality of gas; Whether device for adding odor can detect between knock out drum and point of admission and install and agree with, and reduces the leak case of gas.
Brief description of the drawings
Accompanying drawing 1 is the utility model schematic diagram.
In above accompanying drawing: 1, column; 2, air supply system; 21, refrigerated storage tank; 22, vaporizer; 23, depressurized system; 24, pipeline; 25, knock out drum; 26, use gas point; 27, purifier; 28, device for adding odor; 3, valve; 31, one-way cock.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
A kind of natural gas supply system, comprise one movably column 1 and with the fixing air supply system 2 of column 1 skid, this system comprises refrigerated storage tank 21, vaporizer 22 and the depressurized system 23 of at least one, the air outlet of refrigerated storage tank 21 is connected with the suction port of vaporizer 22 by pipeline 24, the air outlet of vaporizer 22 is connected with the suction port of depressurized system 23 by pipeline 24, the air outlet of depressurized system 23 is connected with the suction port of knock out drum 25 by pipeline 24, and the air outlet of knock out drum 25 connects use gas point 26 by pipeline 24.
In technique scheme, column 1 becomes one group with air supply system 2 by the process Installation of skid, and can move freely, convenient by air supply system be transported to the position needing connect use gas point just can air feed, safety and stability, can save a large amount of construction input and mounting cost, saves the report of pressure piping and builds examination, can greatly shorten the construction period, be that polylith is economized well.
Further, on every segment pipe 24, be equipped with valve 3.Can control speed and the convenient usage degree that detects pipeline 24 of air feed.
Further, the valve 3 between the valve 3 between vaporizer 22 and depressurized system 23 and depressurized system 23 and knock out drum 25 is one-way cock 31.Can effectively avoid the refluence of gas.
