Definitions
- the present invention relates to a container and a pump system.
- liquefied gas pumps deal with the risk of LNG leaking to the outside by placing a temporary plate on the flange at the top of the column (see Patent Document 1, for example). Because LNG is heavier than air in the low temperature range, it is not released into the atmosphere. On the other hand, in the case of cryogenic fluids such as liquefied hydrogen and liquefied ammonia, the specific gravity of the gasified gas is lighter than air, so there is a risk of liquefied hydrogen or liquefied ammonia being released.
- cryogenic fluids such as liquefied hydrogen and liquefied ammonia
- the boiling point of liquefied hydrogen is -253°C
- air mainly oxygen and nitrogen
- liquid oxygen is produced, which poses the risk of explosion
- air freezes both the nitrogen and oxygen pose the risk of damaging the pump.
- ammonia is toxic if it leaks outside, which could pose a health hazard to humans.

- Table 1 below shows the results of tests conducted to confirm the flexibility, airtightness, and presence or absence of fraying or chipping on the surface at extremely low temperatures for four materials (materials A to D).
- material A used was the para-aramid fiber "Kevlar (registered trademark)" manufactured by Toray DuPont Co., Ltd.
- material B used “Silicone-coated heat-resistant sheet flame retardant KW-031” manufactured by Kikuchi Sheet Kogyo Co., Ltd.
- material C used "Double-sided silicone-coated synthetic heat-resistant sheet” manufactured by Kikuchi Sheet Kogyo Co., Ltd.
- test specimens of materials A to D were immersed in liquid nitrogen and cooled sufficiently, then removed from the liquid nitrogen and twisted. The test specimens were then visually inspected to see if they maintained their flexibility and if there were any defects such as chips or fraying on the surface. The airtightness of the test specimens was also checked by a simple gas test (for example, a test in which the test device is divided into two chambers for each material, one chamber is filled with a specific gas and the other chamber is filled with air, and after leaving it for a certain period of time, the increase in the gas concentration in the other chamber is measured). From the results in Table 1, it was found that it is desirable to use material B or material C as the material for the pair of upper and lower cloths 17.
- the rotating ring 15 is provided with a rotating lever 18, and the size of the opening diameter of the pair of upper and lower cable insertion holes 13 can be adjusted at the same time by inserting a hand from the glove box and operating the rotating lever 18 to rotate the rotating ring 15.
- the cloth 17 is twisted, the diameter of the cylinder is narrowed, and as a result, the cloth 17 can be tightly attached to the outer periphery of the cable 8. Therefore, the cloth 17 clings to the installation/pulling cable 8, narrowing the gas flow path and making it possible to suppress gas leakage.
- the opening diameter adjustment mechanism 14 not only adjusts the degree of constriction according to the diameter of the cable 8, but also changes the opening diameter according to the task, allowing it to be opened and closed repeatedly.
- the rotating ring 15, the linear ring 16, and the cloth 17 can each be split into two, from a closed state to an open state. This makes it possible to attach and detach the stuffing box 12 with the cable 8 passing through the container. Also, by adjusting the degree of constriction according to the diameter of the cable 8, leakage can be suppressed even for cables 8 with locally different diameters.
- the rotating ring 15 is provided with a gas inlet 19 for introducing a purge gas into the rotating ring 15.
- a purge gas for example, nitrogen gas or helium gas is used as the purge gas.
- the purge gas flows from the inside of the stuffing box 12 to the top and from the inside of the stuffing box 12 to the bottom, which has the effect of preventing the flow of gas falling from the top to the bottom of the container, and the effect of preventing the flow of gas leaking from the bottom to the top of the container. This makes it possible to prevent highly dangerous gases such as ammonia and hydrogen from leaking to the outside, and to prevent air and nitrogen from falling into the column 2.
- the rotation lever 18 depending on whether the cable 8 is not moving or is moving up and down, the space between the outer circumference of the cable 8 and the cloth 17 can be closed or opened to an appropriate interval, so that the flow rate passing through the space can be adjusted appropriately and the wasteful use and release of a large amount of purge gas can be prevented.
- a stuffing box 12 is provided around the cable through holes 9, 10, and 11, and the stuffing box 12 is provided with an opening diameter adjustment mechanism 14 that adjusts the opening diameter of the cable insertion hole 13. Therefore, by adjusting the opening diameter of the cable insertion hole 13 using the opening diameter adjustment mechanism 14 of the stuffing box 12, it is possible to reduce gas leaking from the cable through hole.
- the opening diameter adjustment mechanism 14 is made up of the rotating ring 15, a pair of upper and lower linear rings 16, and cloth 17, and the pair of upper and lower cloths 17 form a pair of upper and lower cable insertion holes 13. By rotating the rotating ring 15, the opening diameters of the pair of upper and lower cable insertion holes 13 can be adjusted simultaneously.
- purge gas can be introduced into the interior of the rotating ring 15 from the gas inlet 19 provided in the rotating ring 15.
- the purge gas that has flowed into the interior of the rotating ring 15 flows upward and downward inside the rotating ring 15.
- the purge gas flowing upward even if gas attempts to flow downward from above the linear ring 16 on the upper side of the rotating ring 15, the inflow of gas can be prevented by the purge gas flowing upward.
- the purge gas flowing downward even if gas attempts to flow upward from below the linear ring 16 on the lower side of the rotating ring 15, the inflow of gas can be prevented by the purge gas flowing downward.
- the rotating ring 15, the linear motion ring 16, and the fabric 17 can be split into two, so that by changing the rings from an open state to a closed state inside the container, the opening diameter adjustment mechanism 14 can be attached to the cable 8 at the midpoint of the cable 8. Also, by changing the rings from a closed state to an open state, the opening diameter adjustment mechanism 14 can be removed from the cable 8 at the midpoint of the cable 8.
- the containers (buffer container 3, purge container 4) of this embodiment may also be provided with a glove box 30 that is provided inside the container and configured so that a user can insert their hands from outside the container to operate the stuffing box 12, and a work window 31 that is located near the glove box 30 and the stuffing box 12 so that the glove box 30 and the stuffing box 12 can be viewed from outside the container.
- the user when performing maintenance on the liquefied gas pump, the user can insert their hand from outside the container into the glove box 30 inside the container (purge container 3) and adjust the size of the opening diameter of the cable insertion hole 13 using the opening diameter adjustment mechanism 14 of the stuffing box 12, thereby reducing the amount of gas leaking out from the cable penetration hole.
- the opening diameter adjustment mechanism 20 may include an annular main body 21 having a cable insertion hole 13 in the center, and a pair of left and right plate-shaped seal members 22 that are provided on the upper and lower sides of the main body 21 in an openable and closable manner.
- the cable insertion hole 13 is formed in the center of the pair of left and right seal members 22, and the pair of left and right seal members 22 are biased in a direction to close toward the center by the elastic force of a pressing spring 23. Then, the pair of left and right seal members 22 move in the opening direction against the elastic force of the pressing spring 23, whereby the size of the opening diameter of the cable insertion hole 13 can be adjusted.
- the opening diameter of the cable insertion hole 13 can be changed simply by lifting and lowering the cable 8, improving workability.
- the main body 21 of the opening diameter adjustment mechanism 20 is provided with a gas inlet 19 for allowing purging gas to flow into the main body 21.
- the main body 21 of the opening diameter adjustment mechanism 20 can be split into two in the direction in which the pair of left and right sealing materials 22 open.
- the opening diameter adjustment mechanism 20 is also made up of the main body 21, the seal material 22, and the pressing spring 23, and the cable insertion hole 13 is formed in the center of the pair of left and right seal materials 22. Then, by moving the pair of left and right seal materials 22 in the opening direction against the elastic force of the pressing spring 23, the opening diameter of the pair of upper and lower cable insertion holes 13 can be adjusted simultaneously.
- purge gas can be introduced into the main body 21 through the gas inlet 19 provided in the main body 21.
- the purge gas that has flowed into the main body 21 flows upward and downward inside the main body 21.
- the inflow of gas can be prevented by the purge gas flowing toward the upper side.
- the inflow of gas can be prevented by the purge gas flowing toward the lower side.
- the main body 21 of the opening diameter adjustment mechanism 20 can be split into two, so the opening diameter adjustment mechanism 20 can be attached to the cable 8 at the middle of the cable 8 inside the container, or the opening diameter adjustment mechanism 20 can be detached from the cable 8 at the middle of the cable 8.
- the container of the present invention has the effect of preventing gas leakage from the cable penetration hole, and is useful as a pump system equipped with a liquefied gas pump that delivers extremely low temperature liquefied gas such as liquefied hydrogen or liquefied ammonia.
