Abstract
The invention discloses a kind of method that utilization LNG gas stations also serve as city emergency peak regulation source of the gas, after the BOG gases of LNG storage tank are gasified by EAG heaters, after voltage stabilizing to pipeline network of fuel gas in city distribution pressure, then pipeline network of fuel gas in city is metered into.The method that the present invention also serves as city emergency peak regulation source of the gas using LNG gas stations, effectively reclaims BOG, also serves as city emergency peak regulation source of the gas, improves the economy of yard operation, environmental pollution is reduced, with good practicality.
Description
Technical field
The invention belongs to LNG Technology field, it is specifically related to one kind and also serves as city emergency using LNG gas stations
The method of peak regulation source of the gas.
Background technology
Existing skid-mounted gas filling station, typically all by bottom framework, basin, unloading system, pump pond, immersed pump, filling machine with
And the structure member such as booster composition, wherein, booster has supercharging muffler and a supercharging liquid-phase tube, supercharging muffler respectively with
Unload gas returning port and inner pressurd vessel connection, supercharging liquid-phase tube respectively with unloading boost port and immersed pump connect, liquid phase of unloading mouth with it is interior
Reservoir；Basin, filling machine and booster are both secured on bottom framework, and liquid is by boost port and the supercharging liquid phase of unloading in tank car
Pipe enters booster, and liquid returns to tank car after gasifying by charger boost by supercharging muffler, gas returning port of unloading, and completes to increase
Liquid is entered the inner pressurd vessel of basin by liquid phase mouthful of unloading in pressure, tank car, completes to unload.This skid-mounted gas filling station can be in factory
Interior to complete assembling and debugging, being transported to through hole behind scene can come into operation after being fixed by fixing bolt etc., and make gas station
Liquid status to be unloaded are rapidly introduced into, the construction of gas station is improved and unloads liquid efficiency.
But due to the limitation of this liquefied natural gas (LNG) Vehicle Fueling Station technique and operation characteristic so that yard was runed
There is BOG (boil-off gas) irretrievable problem in journey, the economy for both having influenceed yard to run also causes certain shadow to environment
Ring.
The content of the invention
Goal of the invention：For the deficiencies in the prior art, the invention aims to provide one kind to utilize LNG
The method that gas station also serves as city emergency peak regulation source of the gas, effectively reclaims BOG, also serves as city emergency peak regulation source of the gas, improves yard fortune
Capable economy, reduces environmental pollution.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of method that utilization LNG gas stations also serve as city emergency peak regulation source of the gas, the BOG gases of LNG storage tank are added by EAG
After hot device gasification, after voltage stabilizing to pipeline network of fuel gas in city distribution pressure, then pipeline network of fuel gas in city is metered into.
The method that described utilization LNG gas stations also serve as city emergency peak regulation source of the gas, increases pressure regulation meter after EAG heaters
Sledge is measured, urban pipe network is delivered to after the gas progress pressure regulation, metering to emptying.
The BOG gases of the method that described utilization LNG gas stations also serve as city emergency peak regulation source of the gas, storage tank and LNG systems
Enter people's urban pipe network, when accident occurs in yard, system safety valve is opened, excessive gas in emptying station, it is ensured that whole yard peace
Entirely.
The BOG gases of the method that described utilization LNG gas stations also serve as city emergency peak regulation source of the gas, storage tank and LNG systems
Enter people's urban pipe network, when pipeline network of fuel gas in city needs emergency peak regulation, LNG in storage tank can be entered to the gasification of EAG heaters, voltage stabilizing
Enter pipeline network of fuel gas in city afterwards, ensure city dweller's gas.
Beneficial effect：Compared with prior art, the present invention also serves as the side of city emergency peak regulation source of the gas using LNG gas stations
Method, effectively reclaims BOG, also serves as city emergency peak regulation source of the gas, improves the economy of yard operation, environmental pollution is reduced, with very
Good practicality.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the implementation of the present invention
Example, technical scheme is clearly and completely described, it is clear that described embodiment is that a part of the invention is real
Apply example, rather than whole embodiments.
A kind of method that utilization LNG gas stations also serve as city emergency peak regulation source of the gas, the BOG gases of LNG storage tank are added by EAG
After hot device gasification after voltage stabilizing to pipeline network of fuel gas in city distribution pressure, then it is metered into pipeline network of fuel gas in city.
Increase pressure regulation metering sledge after EAG heaters, the gas of emptying is carried out being delivered to city pipe after pressure regulation, metering
Net.
Storage tank and the BOG gases of LNG systems enter people's urban pipe network, when accident occurs in yard, and system safety valve is opened, and is put
Excessive gas in sky station, it is ensured that whole yard safety.
When pipeline network of fuel gas in city needs emergency peak regulation, LNG in storage tank can be entered to the gasification of EAG heaters, entered after voltage stabilizing
Pipeline network of fuel gas in city, ensures city dweller's gas.
The method that the present invention also serves as city emergency peak regulation source of the gas using LNG gas stations, effectively reclaims BOG, and also serving as city should
Anxious peak regulation source of the gas, improves the economy of yard operation, environmental pollution is reduced, with good practicality.
