Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As illustrated in fig. 1 and 2, this utility model provides a kind of gas supply device, including LNG low-temperature storage tank 1, gasifier
2, surge tank 4, pressure regulator 5 and effusion meter 6；Described gasifier 2 is connected with the liquid outlet of LNG low-temperature storage tank 1 by liquid-transport pipe-line 8
Arranging, described surge tank 4 is arranged by the outlet of gas pipeline 9 with gasifier 2, and described pressure regulator 5 and effusion meter 6 pass through
Gas pipeline 9 is sequentially connected with the outlet side at surge tank 4.
In this utility model, also including heater 3, heater 3 is water-bath type electric heater, is arranged on described gas transmission
On the bypass duct of pipeline, its object is to ensure that gas is changed into room temperature under low temperature state.
In this utility model, also include odorization machine 7, connect setting with gas pipeline 9, it is therefore an objective to when preventing gas leak
It is found in time.
In this utility model, gasifier 2 is air-heating type gasifier.
In use, its groundwork process is gas supply device of the present utility model: LNG low-temperature storage tank 1 is as storage
Available is to LNG liquid container, and LNG low-temperature storage tank 1 uses dual-layer high vacuum winding arrangement, top filler can be connected with tank car into
Row storage tank topping up, LNG low-temperature storage tank 1 is from belt controling valve, instrument system, the safe diffusion system of storage tank, by opening bottom row
Liquid root valve, pneumatic stopping valve, liquid is entered air-heating type gasifier 2 by liquid-transport pipe-line 8 after flowing through check valve and carries out liquid supply,
LNG low-temperature storage tank 1 gas phase mouth is connected self BOG gas of recyclable LNG low-temperature storage tank 1 with air-heating type gasifier 2, can be by opening
Gas phase mouth root valve is exhausted, and air-heating type gasifier 2 i.e. carries out storage tank supercharging as LNG low-temperature storage tank 1 from supercharging equipment,
Open discharge opeing root valve bottom LNG low-temperature storage tank 1 during supercharging, pneumatic stopping valve is got rid of liquid and is gasified through air-heating type gasifier 2, then
Open LNG low-temperature storage tank 1 boost port root valve to carry out storage tank and also serve as the master of LNG cryogenic liquid from supercharging, air-heating type gasifier 2
Wanting equipment for gasification, moved towards by the import and export connecting formation flow process of flange with pipeline, LNG liquid and BOG gas are through air temperature type
Controlled to enter water-bath type electric heater 3 by bypass duct 10 by carbon steel ball valve after gasifier 2, be provided with carbon steel ball valve control herein
System gas pipeline 9, as through air-heating type gasifier 2 gasify after gas temperature reach customer demand then can through water-bath type electricity
Heater 3 heats directly unlatching gas pipeline 9 and circulates, and water-bath type electric heater 3 by adding the temperature of hot water, then can be flowed by self
Threading a pipe with cryogenic gas carries out heat exchange, the gas heating after reaching gasification improves the effect of temperature；Gas after heating
Entering and carry out deposit caching, the effect of the pipe safety performance that also improves in surge tank 4, after preventing LNG gasification, amount is too many
Loine pressure drastically raises, and gas can be stored by surge tank 4, and user can store one through above conversion process before making in advance
Portion gas, can save service life during use；Surge tank 4 gas is controlled outflow and the pass of gas by exporting carbon steel ball valve
Closing, gas flows through pressure regulator 5, after the function of pressure regulator 5 is setting certain pressure, controls the pressure size of gas outlet side, gas
Gas pressure, through this equipment, can be converted into the gas of user's desirable pressure value by body, the gas after regulation pressure again with odorization machine 7
The ozone mixing of the inside, after supplied by outlet conduit and Flange joint user's pipeline through effusion meter 6, effusion meter 6 is
A kind of can be set by the user uninterrupted value thus reach control gas flow size equipment, make effluent air in pipeline
Flow is maintained in user's setting value.
