Currently, the commercial applications of hydrogen mainly include high-pressure gaseous hydrogen storage, liquid hydrogen storage, and metal hydrogen storage. Among them, high-pressure gaseous hydrogen storage has problems such as low energy density, easy leakage, and poor safety; liquid hydrogen storage has the problem of insulation failure, resulting in short hydrogen storage time and high cost; metal hydrogen storage has the advantages of immediate production and high energy density, and has been widely researched, developed and applied. Hydrogen is regarded as an ideal energy carrier for its advantages such as green, low-carbon, high efficiency, storability and transportability.

The purity of the direct hydrogen meets the requirements.

[0029] Working principle of the present invention: When hydrogen is produced in the preparation box 1, the first water pump 4 is started, and the reaction water is transported to the spray pipe 6 through the first water suction pipe 5 and the first water delivery pipe 7, so that the spray pipe 6 can spray the reaction water toward the metal hydrogen storage material in the preparation box 1, so as to realize the reaction between the metal hydrogen storage material and the water body to produce hydrogen.

In addition, the purity of the produced hydrogen is detected by the purity detection module, and the hydrogen with insufficient purity can be returned to the impurity removal module for further impurity removal, so as to realize multi-stage impurity removal of hydrogen.

[0030] By utilizing the adsorption force of the first water suction pipe 5 on the water flow and the drainage force of the second water delivery pipe 10, the water flow can push the baffle 302, and the baffle 302 drives the rotating column 301 to rotate under the force of the water flow, so that the rotating column 301 can drive the stirring blade 303 to stir the reaction water in the reaction water tank 3, which is beneficial to improving the cooling and heat dissipation treatment of the reaction water by the refrigeration plate 11.

[0031] When the reaction water is rapidly transported in the first water pipe 7, the first water pipe 7 forms a negative pressure in the working cylinder 1202 through the limiting effect of the electrically controlled one-way valve on the connecting pipe 1204, so that the piston 1203 can move downward in the working cylinder 1202, and the piston 1203 drives the transmission shaft 1205 to move downward synchronously. The spiral slide 1207 exerts an extruding force on the drive shaft 1209 during the movement, so that the transmission shaft 1205 can drive the transmission ring 1208 to rotate during the movement, and the transmission ring 1208 drives the driving ring wheel 1210 to rotate. The pulley transmission composed of the driving ring wheel 1210, the transmission wheel 1212 and the transmission chain 1213 can drive the adsorption fan 1214 to rotate, thereby forming an upwelling airflow in the preparation box 1, which is beneficial to the rapid transportation of the produced hydrogen.

[0032] When the touch controller 1216 is squeezed, the electric one-way valve is controlled to close and the electric pressure relief valve is controlled to open. When the height sensor 1217 reaches the highest point, the height sensor 1217 controls the electric one-way valve to open and the electric pressure relief valve to close through the touch controller 1216. Through the cooperation of the height sensor 1217 and the touch controller 1216, the piston 1203 can move downward under the action of negative pressure and move upward under the elastic force of the supporting spring, which is conducive to the longitudinal reciprocating movement of the piston 1203 in the working cylinder 1202, thereby continuously providing operating driving force for the cooling secondary utilization component 13.

[0033] When the transmission wheel 1212 rotates, the transmission wheel 1212 can drive the turntable 1307 to rotate synchronously. During the rotation of the turntable 1307, the second transmission column 1308 can be driven to move in a circular trajectory. Through the horizontal movement difference during the movement of the second transmission column 1308, the second transmission column 1308, the first transmission column 1306 and the traction plate 1309 can drive the linkage plate 1305 to move back and forth laterally. Since the spray pipe 6 can move laterally through the slider 1302, the linkage plate 1305 can drive the spray pipe 6 to move back and forth laterally synchronously through the linkage rod 1303 during the movement, which is beneficial for the spray pipe 6 to evenly spray reaction water on the metal hydrogen storage material.
