Working principle:
in the assembling process of the ultrahigh-pressure liquid oxygen storage equipment, the first heat insulation cavity 9 and the second heat insulation cavity 14 are respectively filled with the pearly-luster sand material and the novel gel felt material, the density and the heat conductivity of the two materials are very small, the materials are not burnt, are not mildewed or rotten, are nontoxic and odorless, are not corroded, have good fluidity, and can be conveyed by wind pressure to realize automatic filling. The filling process is that after equipment is assembled, the equipment is connected with a flange adapter five 39 through a vacuumizing device, gas in a vacuum insulation cavity one 9 is pumped out, after the vacuum insulation cavity one 9 is pumped out to a certain vacuum degree, the filling compaction is filled with pearly-luster sand, the filling ratio of the filling compaction is more than 1.4, the vacuumizing can be continued while the cavity is filled in the filling process, and three layers of silk screens below 40 meshes are covered on the fully-distributed vacuumizing holes of the vacuumizing pipe wall in order to prevent the vacuumizing pipe from being blocked by the pearly-luster sand. After the pearlescent sand is filled, and the vacuum degree of the equipment is detected to reach the preset value, the vacuumizing valve is closed, the vacuum degree of the equipment is monitored at any time by using the vacuum meter, and once the vacuum degree is higher than the preset value, the vacuumizing valve is required to be opened to continue vacuumizing operation.
After the installation and pre-detection of the equipment are confirmed, the equipment is firstly connected with the flange 44 of the liquid level meter and one group of flange adapter pieces I22 respectively through a low-temperature tank wagon, low-temperature liquid oxygen is filled into the inner cylinder 2 through the liquid oxygen filling pipe 24 and the liquefied medium supply pipe 21, and the equipment can be connected with the other group of flange adapter pieces I22 through a liquid oxygen pressurizing device in the filling process. The liquid oxygen is filled at the two sides simultaneously to avoid the liquid oxygen from absorbing heat and vaporizing as much as possible, after the liquid oxygen in the inner cylinder 2 is vaporized to a certain degree and the pressure is increased and the filling cannot be continued, the inner cylinder 2 is filled with high-pressure nitrogen for pressurization so as to re-liquefy the liquid oxygen medium, the liquid oxygen medium is filled while being pressurized to reach the preset pressure and the liquid level height, and then the liquid oxygen medium is supplied to a test bed for test after the test is completed. And on the same day, the internal pressure of the inner cylinder 2 is released to be within a safe value and kept, if the test is planned to be continuously carried out every day, the liquid oxygen in the inner cylinder 2 cannot be completely released, if the test is planned to be not carried out for a long time, the whole liquid oxygen in the inner cylinder 2 needs to be discharged, and the filling is carried out before the next test.
In addition, in practical use, it should be noted that:
1. when liquid oxygen is filled for the first time, the liquid oxygen is slowly filled (a valve on a cryogenic tank car is slowly opened) and then gradually accelerated, so that the thermal shock damage to the inner cylinder 2 is reduced, and the evaporation amount of liquid is reduced. The valve is opened and closed slowly in the running process, so that the valve is prevented from being too fast and strong, and electrostatic spark is avoided.
2. The pressurizing valve on the liquid oxygen pressurizing device is closed in all the time without pressurizing, so that the evaporation loss is increased due to air leakage in the pressurizing valve is avoided.
3. The ultra-high pressure liquid oxygen storage device in use generally does not need to drain the liquid of the inner cylinder 2, so that the inner cylinder 2 is prevented from recovering to normal temperature, excessive liquid is prevented from being lost when the liquid is refilled, if the device is deactivated for a long time and the liquid is drained economically, the liquid is drained completely, all valves are closed, the inner cylinder 2 is kept at the pressure of about 0.02MPa, and therefore moist air and dust are prevented from entering the pipeline and the inner cylinder 2, the tube valve is prevented from being blocked, and the gas purity is influenced.
The equipment is a fixed vacuum powder adiabatic cryogenic storage tank, the medium is liquid oxygen/liquid nitrogen medium, the temperature of the medium of the inner cylinder 2 is minus 183 ℃, and the working pressure is 0-42 MPa alternating pressure. The outer jacket 1 is vacuumized after being filled with the pearly-lustre sand powder, the working pressure is less than or equal to 10pa, and the working temperature is-20 to normal temperature.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
