ことにある。There are various problems in such a conventional technique. That is, in the method of increasing the pressure of the liquid using the liquid pump and then vaporizing the liquid, it is necessary to precool the pump before starting it, which requires a lot of labor and cost. Further, since the liquid pump has a rotating mechanism, troubles such as poor suction of liquid are likely to occur, and a great deal of labor and cost are required for countermeasures and maintenance. In addition, in the method of evaporating the liquid at low pressure and then boosting it with a high-pressure gas compressor, there are multiple compressors with multi-stage compression mechanism, or compression with a combination of reciprocating type and diaphragm type. A machine was required, the mechanism was complicated in any case, and troubles were likely to occur during its operation, and much labor and cost were spent for its use and maintenance. As described above, all of the conventional methods require a high-pressure rotating mechanism, which is highly dangerous, and it is necessary to always pay close attention to sudden failures, not to mention maintenance. . The present invention has been made to solve such conventional problems, and an object thereof is to provide a method for generating high-pressure gas that does not require a rotating mechanism, thereby reducing labor and cost required for operation and maintenance. Especially.

とが好ましい。In the high-pressure gas generating method of the present invention, the low-temperature liquid is first introduced into a pressure-insulating cylinder which has been heat-insulated and optionally pre-cooled to reach 80% or more of its volume. This liquid is
Next, when the valve between the pressure resistant cylinder and the evaporator is opened, the gas pressure in the pressure resistant cylinder sends the gas to the evaporator via the trap. Since the evaporator is maintained at the atmospheric temperature, the liquid absorbs atmospheric heat and is vaporized into a high-pressure gas. This high-pressure gas is sent to and stored in the air accumulator. When such an operation is repeated as a cycle, the gas pressure of the air accumulator sequentially rises,
It is possible to obtain a high-pressure gas of several hundred atmospheric pressure without using a rotating mechanism. The pressure that can be reached depends on the physical properties of the liquefied gas and the setting conditions such as temperature and pressure, but can be increased to 500 to 700 atm. At this time, the temperature of the liquid sent to the pressure-resistant tube must be kept as low as possible. For this reason, the pressure-resistant tube is thermally insulated, preferably cooled beforehand with liquefied nitrogen or the like, and then the liquid is introduced. Further, the compressed gas, which has a small volume left in the pressure-resistant cylinder when the liquid is introduced, is used as a thrust for sending the liquid to the evaporator, but is cooled to be a low-pressure gas when the sending is completed. Such gases could be released into the atmosphere prior to the next cycle,
It is preferable to collect it in consideration of economical efficiency and pollution.

ルに移行し、同様な操作が所定回数反復される。Next, a specific example of a method for generating high-pressure gas using this apparatus will be described. First, from the closed state of all the automatic valves and the manual valves, as a preparatory operation, the automatic valve V 4 is opened to allow liquefied nitrogen to flow into the coil tube 12 to cool the pressure resistant cylinder 10 to a desired temperature. Next, the automatic valves V 1 and V 2 are set by the timer.
However, when the manual valve V 9 is opened, the liquid flows from the liquid storage tank 40 into the pressure resistant cylinder 10 through the pipe 11 by its internal pressure. A part of the vaporized gas generated in this process is sent from the manual valve V 9 to the low pressure system. When the pressure cylinder 10 is filled with 80% or more of the liquid, the automatic valves V 1 , V 2 and V 4 are closed and the automatic valve V 3 is closed.
When opened, the liquid in the pressure resistant cylinder 10 is sent from the pipe 11 to the high-pressure evaporator 20 through the check valve V 5 , the room temperature trap T ′, and the check valve V 6 by the internal pressure. Here, the liquid absorbs atmospheric heat to become high-pressure gas at room temperature, and passes through the check valve V 7 to generate high-pressure gas accumulator 3
Stored at 0. After that , the automatic valve V 2 is opened, and the gas that has pushed out the liquid in the pressure resistant cylinder 10 freely expands into the low pressure system through the opened manual valve V 9 and the low pressure gas accumulator 60.
Will be collected. Due to this gas expansion, the pressure cylinder 10 has 2
It is kept at a low temperature of 52 to 143K. When one cycle of the driving operation is completed in this way, the operation automatically shifts to the next cycle, and the same operation is repeated a predetermined number of times.
