Operation principle：
The workflow of LNG storage tank adjusting saturated vapor pressure is combined in the utility model specifically, B tanks 3 are in fueling process
In it is in operating status, A tanks 2 are in standby.B tanks 3 will produce BOG in operational process, increase B tanks 3 with BOG amounts
LNG saturated vapor pressures can increase, will be to the aerating of LNG when the LNG saturated vapor pressures of B tanks 3 are increased to beyond normal value
Journey has an adverse effect, and causes the exceeded alarm of aerating pressure, filling machine safety valve superpressure the problems such as diffusing with aerating pipeline superpressure.
Open at this time B tanks 3 be responsible for and A tanks 2 be responsible between connection pneumatic control valve 12, the BOG in B tanks 3 will be responsible for 11 by B,
A supervisors 10 in pneumatic control valve 12 and A tanks 2, enter the top in A tanks 2, when the saturated vapor pressure in B tanks 3 drops to normally
After value, pneumatic control valve 12 is closed, realizes the effect for adjusting LNG saturated vapor pressures in B tanks 3.
The workflow that LNG composite cans BOG is recycled in the utility model is specifically, B tanks 3 are in operation in fueling process
State, A tanks 2 are in standby.B tanks 3 will produce BOG in operational process, be steamed as the LNG for increasing B tanks 3 of BOG amounts is saturated
Vapour pressure can increase, and the temperature of the LNG of B tanks 3 also can accordingly rise, in order to avoid the BOG in discharge B tanks 3 causes unnecessary wave
Take and pollute the environment, opens the valve V8 being located on B tanks supervisor 11 at this time, then open and 52 communicating pipe of inlet under A
Valve on road, BOG in B tanks 3 by inlet 52 under B supervisors 11, valve V8, B gas phase pipe, composite can exterior line, A,
The lower part for entering A tanks 2 is entered the BOG of A tanks 2 by B tanks 3 since the LNG temperature of A tanks 2 is less than the temperature of the generation of B tanks 3 BOG
It is liquefied again by the LNG of A tanks 2, BOG is recycled recycling.
LNG unloads workflow specifically, when the LNG of the B tanks 3 of composite can is in low liquid level in the utility model,
LNG tank cars, which drive into, to be unloaded parking stall connection and unloads hose, is ready for LNG and is unloaded operation.A tanks 2 are in operating status at this time, unloading
Aerating can be carried out to LNG automobiles in the process.Due to A tanks 2 operating pressure be adjusted saturated vapor pressure and recycling BOG with
Afterwards, it is higher than the operating pressure of B tanks 3, before LNG tank cars unload LNG to B tanks 3, needs the saturated vapour pressure for suitably reducing A tanks 2,
So as to normal aerating.Specifically, opening the valve V7 being located on A supervisors 10, LNG tank car liquid phase valves are opened, in A tanks 2
BOG is by A supervisors 10, valve V7 and the A gas phase mouth 14 on A supervisors 10, then by unloading gas phase hose and LNG tank cars go out
Liquid valve enters the lower part of LNG tank cars, and through the lower LNG of excess temperature, cooling is liquefied as LNG to BOG again again, the pressure in A tanks 2
Power reach normal value, LNG tank car pressure reaches unload pressure after, close valve V7 and LNG tank car liquid valve, start in B tanks 3
LNG is unloaded, full LNG is unloaded until 3 liquid level of B tanks reaches the upper limit.At this point, B tanks 3 enter working condition, LNG tank cars unload remaining LNG
To A tanks 2, completion entirely unloads liquid process.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
