Carry out most of fluid in cooler bin, only to sacrifice small portion of fluid as cost, it is possible to realize the elimination of fluid thermally stratified layer in case
And the control of tank pressure, be most prospect at present cryogenic propellant tank pressure control mode.
Existing thermodynamics gas extraction system mainly include low-temperature storage tank body, circulating pump, Concentric casing heat exchanger, choke valve,
Air bleeding valve and other pipelines facility.It is that downflow type is concentric that U.S. NASA, which studies core heat exchanger components in thermodynamics gas extraction system,
Double-tube heat exchanger, its heat exchange efficiency are relatively low；Although the Patents CN105444591A of domestic applications is done on heat exchangers
Improve, employ three double-tube heat exchangers, while the interlayer between inner tube and intervalve sets spiral winding to disturb silk, but do not have
There is the flow direction for changing two heat exchanging fluids, still limited by parallel flow heat exchanger heat exchange efficiency.In addition, above-mentioned two systems dress
Put the cold energy use for not accounting for exhaust.Therefore, heat-exchange system, the cooling insulation system of a set of high efficient and reliable are designed, to having
Effect reduces casing leakage heat, realizes the good control of tank pressure and eliminate fluid thermally stratified layer in case have important value and meaning.
The content of the invention
The defects of it is an object of the invention to overcome above-mentioned prior art to deposit, propose a kind of low temperature with pressure control device

The present invention operation principle be：
The invasion of external environment condition leakage heat raises the temperature for causing cryogen, and produces serious thermal stratification；Thermally stratified layer
The phase transformation evaporation of cryogen is will further facilitate, in turn results in the rise of tank pressure.To realize rationally decompression, need to take
The pressure control measure of effect.For apparatus of the present invention, when box house cryogen has certain degree of supercooling, only open the circulation pump
Can realizes the reduction of tank pressure.
Now, cryogenic propellant is under the suction of circulating pump, from bottom half through big fluid streams circulation line, from casing top
Portion enters reverse-flow double-tube heat exchanger inner tube, through heat exchanger after through vertical spray wands spray into box house gas-liquid phase space.
Under the cooling of supercooling cryogen, gas phase temperature reduces, so that tank pressure also reduces.Once tank pressure is reduced to institute
When setting low pressure limit, circulating pump is stopped.Under outside leakage heat, tank pressure will raise again, once it is increased to set
The tank pressure upper limit is put, now circulating pump is again turned on, and under the cooling of injection fluid, tank pressure reduces again, therefore
The stage, fluctuating change of the tank pressure by experience between pressure control bound.
However, continuing over time, invade the outside of casing and leak that hot total amount is more and more, although simple injection mixing
Can reach reduces the purpose of tank pressure, but the temperature of cryogen gradually rises in case.When fluid temperature (F.T.) liter in case
During high certain limit（Saturation temperature corresponding to casing pressure control lower limit）, now only by individually projecting the fluid onto gas-liquid phase region
Good pressure control effect can not be not only played, can also cause increasing sharply for tank pressure.Therefore, now need to open throttling refrigeration
Pattern carries out tank pressure control.
Cryogenic propellant, from bottom half through big fluid streams pipeline, enters from casing top and covered under the suction of circulating pump
Heat exchange of heat pipe inner tube；Simultaneously under the effect of casing inside and outside differential pressure, small portion of fluid is through choke valve reducing pressure by regulating flow, through shallow bid fluid hose
The annular chamber that road enters between inner tube of heat exchanger and outer tube；Inner tube of heat exchanger monophasic fluid flows into the two-phase in inner and outer pipes annular chamber
Row reverse flow exchanges heat；Two-phase fluid absorbs the heat of inner tube and box house high temperature fluid and the gasification that heats up, and eventually becomes
Saturated gas or high-temperature gas discharge casing；Under the cooling of two-phase fluid, temperature reduces inner tube of heat exchanger monophasic fluid, and most
Heat exchanger bottom is converged in eventually；The spray wands that are arranged symmetrically of the cooled fluid of heat exchanger bottom through setting are converged in directly to spray
Gas-liquid phase region in case is mapped to, by bringing cold into liquid phase, gas-liquid phase region thermal stratification is eliminated, realizes tank pressure control.
It is changed into the expanded machine decompression cooling of high-temperature exhaust air of saturation or superheat state, into being wrapped in casing between outer tank body
Cooling coil, be high-temperature gas by absorbing leakage thermal change outside most of casing, through air bleeding valve discharge cooling coil, effectively
Reduce casing leakage heat.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various change and change, the ordinary skill people of this area
