Description
Technical field
The utility model relates to the pressurized container field, particularly relates to a kind of cryogenic liquid basin with maximum charge limitation function.
Background technique
Usually when in basin, filling cryogenic liquid; Confirm a maximum filling weight; Guarantee to leave certain safety space in the jar; Holding the basin gas that liquid produces because of the heat absorption vaporization in the basin in actual use, reach safety valve and preestablish discharge pressure and the time of the gas of outwards releasing thereby prolong gas pressure, we claim thisly to be " holding time " from the cryogenic liquid vaporization until the time of the gas of outwards releasing usually.If 100% fills cryogenic liquid in the basin, there is not to hold the safety space of gasifying liquid in the basin, " holding time " of basin can be shortened greatly.
Prior art has 3 kinds for the measure of confirming maximum filling weight at present: first kind is weight method.Promptly judge the maximum filling weight whether reached regulation, reached and just stop to charge with weighing apparatus.But implementation methods that should technology bothers very much, and limited by equipment itself and environmental conditions.Second kind is press over system.The maximum of promptly in basin, stipulating fills the liquid level place spill pipe is set, and when liquid reached the regulation liquid level, cryogenic liquid cognition flowed out from spill pipe, and stops topping up immediately.But being suitable for, this method do not forbid direct cryogenic liquid, like liquid hydrogen and LNG Liquefied natural gas etc. to the nature overflow.The third is the instrument check method.Whether the cryogenic liquid that promptly adopts responsive element of liquid level or level meter to detect in the basin reaches the regulation liquid level, reaches promptly to stop topping up.But owing to have great amount of bubbles in the cryogenic liquid when charging, the liquid level that instrument is sensed with jar in an actual liquid level have very mistake, inadvisable.
The patent No. is that 200420027074.6 patent " has the cryogenic liquid basin that charges from limitting function " and solves the defective in the above-mentioned technology basically, aspect the basin of the disclosed cryogenic liquid basin of this patent technology when tank body 100% fills held time very big improvement has been arranged.This technology is being carried out cryogenic liquid when charging for the cryogenic liquid basin of a sky, when in the main basin during 100% full of liquid, in auxilliary jar, also remain with main jar in the volume of said safety space equate or bigger spatial volume.But, because a jar interior vaporization space is not invariable.Such as for an idle a period of time; The basin of half the (50%) liquid still is housed in jar; In spacing auxilliary jar in the basin half the cryogenic liquid is arranged also; If this moment is when carrying out once more topping up to it because that the gas-phase space capable of using in the main basin spacing auxilliary jar has just reduced is half the, just can't be for main basin charge the safety space that provides enough once more.

Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Embodiment 1; See also Fig. 1, a kind of cryogenic liquid basin with maximum charge limitation function comprises: main body jar 1 and spacing auxilliary jar 2; Said main body jar is provided with liquid inlet pipe 3 and drain pipe 4; Said spacing auxilliary jars 2 are arranged on main body jar 1 inside, are provided with a pipeline 5 in said spacing auxilliary jar 2, and said spacing auxilliary jar 2 is connected through pipeline 5 with main tank body 1.
In addition, said spacing tank body 2 is connected with the tank skin of main tank body 1 and both are mutually one.
In addition, said pipeline 5 upper ends are positioned at main body jar 1 top, and said pipeline 5 lower ends are positioned at spacing auxilliary jar of 2 bottoms.
In addition; Said liquid inlet pipe 3 is arranged on main body jar 1 top, and said drain pipe 4 is arranged on main body jar 1 bottom, and said liquid inlet pipe 3 is provided with topping up connection set 7; Said liquid inlet pipe 3 is connected with liquid feeding rifle 10 through topping up connection set 7, and said liquid feeding rifle 10 is provided with monitoring device 6.
In addition, said monitoring device 6 is flow monitoring device or pressure monitoring device.
In addition, also be provided with relief valve 8 on said spacing auxilliary jars 2, when causing pressure excessive owing to reasons such as obstruction for spacing auxilliary jar 2, relief valve 8 is opened automatically, reduces the pressure in the spacing auxilliary jar 2.
In addition, be provided with heat-transfer apparatus 9 between said main body jar 1 and the spacing auxilliary jar 2.
The concrete working principle of cryogenic liquid basin that the utlity model has maximum charge limitation function is following: liquid enters into main body jar 1 through liquid inlet pipe 3, and when liquid in the main body jar 1 charges near 100% the time, gas enters into spacing auxilliary jar 2 through pipeline 5 in the main body jar 1; Make spacing auxilliary jar 2 pressure rise; Main body jar 1 interior quick minimizing this moment along with space in the jar, the pressure fast rise causes the flows in the liquid inlet pipe 3 to descend; The lasting decline of flow charges at last and stops; Charge stop after, spacing auxilliary jar of 2 temperature that are in the cryogenic liquid parcel descend, spacing auxilliary jar 2 the temperature with cryogenic liquid is consistent gradually; Pressure following temperature in spacing auxilliary jar 2 descends and descends, and a small amount of cryogenic liquid in the main body jar 1 enters in spacing auxilliary jar 2 through pipeline 5; After the liquid in the main body jar 1 slowly uses consumption; Pressure in the main body jar 1 continues to descend; Thereby make spacing auxilliary jar 2 pressure be higher than main body jar 1, under action of pressure, spacing auxilliary jar 2 interior liquid flow back in the main body jar 1 through pipeline 5; Thereby make when main body jar 1 fills once more that spacing auxilliary jar 2 is empty.
Embodiment 4, see also Fig. 4, a kind of cryogenic liquid basin with maximum charge limitation function; Comprise: main body jar 1 and spacing auxilliary jar 2; Said spacing auxilliary jars 2 are arranged on main body jar 1 top, are provided with a pipeline 5 in said spacing auxilliary jar 2, and said spacing auxilliary jar 2 is connected through pipeline 5 with main tank body 1; Pipeline 5 is not arc; Be said pipeline 5 upper end parts and stretch out spacing auxilliary jar 2 and be positioned at main body jar 1 top, said pipeline 5 lower ends are positioned at spacing auxilliary jar of 2 bottoms, and all the other structures and working principle are all with embodiment 1.
Be different from existing technology; The cryogenic liquid basin that the utlity model has maximum charge limitation function is simple and reasonable, safe and reliable, easy to operate, manufacturing and maintenance cost are low; Can guarantee repeatedly to dash repeatedly when irritating, the safety space of guaranteeing requirement is avoided overcharging accident effectively and is taken place.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
