Description

Technical Field

[0001] The present invention belongs to the field of new energy technology, and in particular relates to a multi-channel solid-state hydrogen storage tank activation and hydrogen charging device. Background Art

[0002] The hydrogen storage materials filled in the solid-state hydrogen storage tank will inevitably come into contact with air during the filling process, causing deactivation, and the hydrogen storage materials cannot absorb hydrogen. Therefore, after the hydrogen storage tank is filled, it needs to be activated to have normal hydrogen storage capacity. In addition, after the solid-state hydrogen storage tank has been used for a period of time, it also needs to be activated to improve the hydrogen storage capacity of the material. At present, ordinary activation devices can only activate one solid-state hydrogen storage tank at a time. The activation can only be completed by heating the solid-state hydrogen storage tank and purging it with inert gas (such as nitrogen), vacuuming, pressurizing and filling it with hydrogen. This can barely meet the needs of experiments and small-scale applications at this stage. Once the demand for hydrogen energy explodes, the current activation devices are far from meeting the activation needs of a large number of solid-state hydrogen storage tanks.

[0003] The invention patent with application number CN02146722.6 and titled "Hydrogen Tank Charging and Activation Treatment Device" discloses a hydrogen tank charging and activation treatment device, which includes a hydrogen tank container, which is equipped with a plurality of partitions to form a plurality of receiving spaces for receiving a plurality of inserted hydrogen tanks, a spacer back plate is arranged inside the hydrogen tank container, and a plurality of hydrogen tank snap-on seats are arranged at intervals to be combined with the inserted hydrogen tanks; a hydrogen storage tank for supplying the hydrogen tank The invention also provides a hydrogen storage tank with a hydrogen source required for hydrogen filling and activation operations; a cold water tank for supplying cold water required for cooling the hydrogen storage tank during the hydrogen filling operation; a vacuum pump for extracting gas from the hydrogen storage tank during the activation operation of the hydrogen storage tank; a warm water tank for supplying warm water required for heating the hydrogen storage tank during the activation operation; the hydrogen storage tank integrated processing device of the invention can perform the hydrogen filling operation procedure of hydrogen storage alloys and the activation operation procedure of hydrogen storage alloys, but requires a lot of manual operation, and the efficiency and safety need to be improved.

[0004] At present, with the successful application of small solid-state hydrogen storage tanks in electric bicycles (with small battery stacks), a 2L solid-state hydrogen storage tank can drive a national standard electric bicycle for 50 kilometers. It has many advantages such as no charging and quick replacement. If the application of solid-state hydrogen storage tanks in electric bicycles is promoted, the demand for activation and hydrogen filling of solid-state hydrogen storage tanks will undoubtedly be huge.

[0005] Small solid-state hydrogen storage tanks currently used in electric bicycles, in order to reduce the risk of hydrogen leakage, should generally be equipped with a manual switch valve in addition to a quick-connect plug. Users can open the valve according to their needs when using it to establish a passage and drive the electric bicycle. At present, the main method of hydrogen filling or activation for such solid-state hydrogen storage tanks with switch valves is to manually connect the pipeline to the solid-state hydrogen storage tank and then perform hydrogen filling or activation operations, which is inefficient. Workers must also strictly follow the operating procedures when operating to avoid safety problems.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below through examples so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof. Example

[0031] like Figure 1-2As shown, a multi-channel solid-state hydrogen storage tank activation and hydrogen charging device is used to activate or charge a solid-state hydrogen storage tank, comprising a cabinet and a gas circuit system arranged in the cabinet, wherein the gas circuit system at least comprises a hydrogen pipeline, an inert gas purge pipeline, an exhaust pipeline, and a vacuum pipeline; and further comprises a tank body connecting pipeline extending out of the cabinet, wherein the tank body connecting pipeline comprises an air pipe 1 and a plurality of connecting devices, wherein one end of the air pipe 1 is respectively connected to the hydrogen pipeline, the inert gas purge pipeline, the exhaust pipeline, and the vacuum pipeline, and the other end of the air pipe 1 is connected to the plurality of connecting devices in series or in parallel;

[0032] The connecting device comprises an upper connector 3 with a pneumatic diaphragm valve 2 and a lower connector for connecting to the valve of a solid hydrogen storage tank, and the upper connector 3 and the lower connector are connected through a connecting pipe 4; when the solid hydrogen storage tank is activated or charged with hydrogen, the lower connector is connected to the valve of the solid hydrogen storage tank through the lower connector; when the lower connector is disconnected from the valve of the solid hydrogen storage tank, at least the lower connector of the upper connector 3 and the lower connector is automatically sealed;

[0033] The solid-state hydrogen storage tank heating device 6 is provided on the outside of the cabinet, and a plurality of solid-state hydrogen storage tank placement positions 601 are provided inside the solid-state hydrogen storage tank heating device 6. The tank body connecting pipeline is provided above the solid-state hydrogen storage tank heating device 6, and each connecting device corresponds to a solid-state hydrogen storage tank placement position 601. In this embodiment, the solid-state hydrogen storage tank heating device 6 adopts a water bath pot with a heating upper limit temperature of 80-100°C, and the solid-state hydrogen storage tank heating device 6 has an upper cover 602, which is opened or removed when the equipment is in operation.

[0034] The tank connecting pipeline also includes a mass flow controller 7 to control the amount of hydrogen released by a single hydrogen storage tank at a specific position on the activation line and calculate the cumulative flow rate, thereby realizing the function of spot checking the activation effect of a batch of hydrogen storage tanks.

[0035] The connecting pipe 4 is a high-pressure resistant stainless steel hose; when activating or charging the solid-state hydrogen storage tank, first place a plurality of solid-state hydrogen storage tanks on the solid-state hydrogen storage tank placement position 601, then manually connect the lower connector to the solid-state hydrogen storage tank valve, and then manually turn the knob to open the valve for activation or hydrogen charging operations.

[0036] The number of the connection devices and the solid hydrogen storage tank placement positions 601 are both 12. The number of the connection devices and the solid hydrogen storage tank placement positions 601 can reach 100, so that the activation task of nearly 1,000 solid hydrogen storage tanks can be completed at most in one night. At present, the commercial version has 12 activation hydrogen charging positions as a better choice. Example

[0037] like Figure 3As shown, it is similar to Example 1, except that a knob-type valve with a quick-connect plug is provided on the upper part of the solid-state hydrogen storage tank, and the valve is switched on and off by turning the knob. The solid-state hydrogen storage tank with a quick-connect plug and a knob-type valve has a better application prospect due to its safety. Compared with the solid-state hydrogen storage tank with only a quick-connect plug, it has an additional manual knob-type valve, and when applied to an electric bicycle, it has better operability and safety.

[0038] The connecting pipe includes an upper high-pressure hose 16 and a lower high-pressure telescopic pipe 8, the high-pressure telescopic pipe 8 includes a high-pressure inner pipe 11 and an outer pipe 10 which is slidably mounted on the high-pressure inner pipe through a spring 13, and the lower connector is arranged at the lower end of the high-pressure inner pipe;

[0039] The outer tube 10 is provided with a replaceable bracket 9, and the travel of the bracket 9 is not less than 1 / 2 of the total travel of the knob, so that the bracket 9 can completely close the valve or at least half open the valve. In this embodiment, the bracket 9 has a long side 902 and a short side 901; the short side 901 of the bracket 9 is connected to the outer tube 10, and the long side 902 of the bracket 9 is arranged vertically downward; the long side of the bracket 9 is processed with a rack 903 or a rough surface (the rack can be arranged on the side, inner side or outer side of the long side, depending on the specific position of the rack knob) to promote the knob to rotate; in this embodiment, the side of the long side is provided with a rack 903.

[0040] It also includes a lifting frame rod 12 with a driving device; the lifting frame rod 12 is connected to the outer tube 10. When the lifting frame rod 12 is in operation, it drives the high-pressure resistant telescopic tube 8 to move up and down, first connecting the lower connector 5 with the quick-connect plug of the solid hydrogen storage tank valve (in this embodiment, the downward movement of the lifting frame rod 12 makes it possible for the lower connector 5 to always maintain a certain pressure on the quick-connect plug of the solid hydrogen storage tank valve due to the action of the spring during the hydrogen filling or activation process, thereby achieving a sealed connection); then the lifting frame rod 12 drives the outer tube 10 to continue to move downward, the long side of the bracket 9 contacts the knob of the valve and causes the knob to rotate to open the valve, after the activation or hydrogen filling is completed, the lifting frame rod 12 drives the outer tube 10 to rise, so that the knob closes the valve, and then the lifting frame rod 12 continues to rise, and the outer tube 10 drives the lower connector 5 on the inner tube to disengage from the quick-connect plug of the solid hydrogen storage tank valve.

[0041] When the solid-state hydrogen storage tank is placed in the solid-state hydrogen storage tank placement position 601, the placement postures of the multiple solid-state hydrogen storage tanks are consistent, and the edge of the solid-state hydrogen storage tank valve knob on the opening direction is directly below the long side of the bracket 9 without obstruction, so that when the lifting frame rod 12 drives the outer tube 10 to move up and down, the long side of the bracket 9 can smoothly turn the knob. The solid-state hydrogen storage tank should be stably fixed in the solid-state hydrogen storage tank placement position 601, so that when the lifting frame rod 12 drives the long side of the bracket 9 to turn the knob, the bracket 9 maintains stable contact with the knob.

[0042] The outer tube 10 is provided with a strip-shaped limiting hole 14 along the length direction, and the inner tube is adapted to be provided with a limiting column 15 sliding along the strip-shaped limiting hole, thereby playing a role in limiting the stroke of the outer tube 10 .

[0043] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
