Operation principle of the present utility model
When LNG tank car enters after the unloading deck of LNG gasification station, the liquid in groove is because Action of Gravity Field is from flowing to booster, liquidAfter booster absorbs heat gasification, return to the gas-phase space on LNG tank car top, make the interior gas-phase space pressure of tank carRaise, so the LNG in tank car can flow into LNG storage tank by another liquid pipe, completes and unloads; The LNG of LNG storage tankBecause Action of Gravity Field flows to booster, liquid after gasifier absorbs heat gasification, return storage tank top gas-phase space, useTank inside gaseous pressure raises, and so the LNG in storage tank can be flowed into and be used gas point by another liquid pipe, for.
Unloading in pressurization. By tank car respectively with the supercharging liquid phase mouth a that unloads, the supercharging gas phase mouth c that unloads, unload liquid mouth b and be connected,Open pipe valve a, b, c, the pipe valve f5 of storage tank supercharging liquid phase mouth (storage tank inlet) f of storage tank, blinds off a lineValve d, pipe valve I, the liquid in tank car enters into booster by the supercharging liquid phase mouth a that unloads, and is gaseous state by liquid state gasification,Enter in tank car by the supercharging gas phase mouth c that unloads again, tank car pressure is raise, higher than pressure of storage tank. Under the effect of pressure reduction,Liquid in tank car is transported in storage tank, thereby is reached by storage tank supercharging liquid phase mouth (storage tank inlet) f that unloads liquid mouth b, storage tankTo the supercharging object of unloading.
In storage tank pressurization, open pipe valve d, f, e, h, i, blind off a line valve a, b, c, g, in storage tankLiquid, flows out from storage tank supercharging liquid phase mouth (storage tank inlet) f of storage tank, enters in booster liquid state by valve f, iLNG by booster, be gasificated as gaseous state. The natural gas of gaseous state enters into storage by valve d, storage tank supercharging gas phase mouth dIn tank, thereby improve pressure of storage tank, ensure that LNG is by storage tank liquid outlet e, client's supply opening h is to downstream feed flow.
