The economic development has increasingly increased demands for new energy, and in order to solve the problems of insufficient energy supply and environmental pollution, the use of fossil fuels must be reduced, and the input of renewable energy sources is increased. Among them, renewable energy sources such as hydrogen energy, solar energy, biomass energy and the like are popular choices, and particularly, hydrogen energy is recognized as the most promising energy carrier at present due to the characteristics of no pollution, storability, transportable, wide source, cleanliness, high heat value, rich application scene, low ignition point and the like.

Hydrogen energy sources are in gaseous form under normal conditions and are flammable and explosive, which presents great difficulties in their storage and transportation.

In this embodiment, as shown in fig. 2 and 4, in order to make the volume of purified water added into the water tank 102 not overflow due to too much or not too little for subsequent electrolysis, a first liquid level sensor 1025 and a second liquid level sensor 1024 connected to the controller module 108 are disposed outside the water tank 102, where the first liquid level sensor 1025 is a high liquid level sensor and the second liquid level sensor 1024 is a low liquid level sensor, so that when purified water is added into the water tank 102, the water level is enough when the first liquid level sensor 1025 is reached, at this time, the controller module 108 controls the corresponding alarm 113 to alarm, thereby reminding the operator to stop adding water, and when the water level is reached to the second liquid level sensor 1024, the corresponding alarm 113 is controlled to alarm, thereby reminding the operator to add water into the water tank.

In this embodiment, as shown in fig. 2 and 4, in order to prevent the purification resin 1032 in the purification chamber 103 from being damaged due to the excessive water temperature, on the one hand, the water temperature has an important effect on the operation efficiency, operation performance, etc. of the PEM electrolyzer 104, and in order to maintain the temperature of the PEM electrolyzer 104 in an optimal temperature range, the temperature of purified water entering the PEM electrolyzer 104 needs to be controlled. Therefore, a water temperature sensor 1026 is provided in the water tank 102, and the water temperature sensor 1026 is electrically connected to the controller module 108, so that the water temperature in the water tank 102 can be monitored in real time; if the water temperature in the water tank 102 is detected to be too high (e.g., above 60 ℃), the controller module 108 will stop the electrolysis operation of the PEM electrolyzer 104 and send a corresponding high temperature warning signal to prompt the operator to replace purified water in the water tank 102 or to cool the water tank 102 until the water temperature is below 60 ℃, thereby ensuring that the water temperature entering the PEM electrolyzer 104 is always no higher than 60 ℃.

In this embodiment, as shown in fig. 2 and 4, in the process of generating hydrogen and oxygen by using the PEM electrolyzer 104, the purification chamber 103 and the water tank 102, since the PEM electrolyzer 104, the purification chamber 103 and the water tank 102 are communicated with each other, the oxygen is released to the outside of the housing 101 through the purification chamber 103 and the water tank inlet 1021 for exhausting, and in order to maintain the gas pressures of the PEM electrolyzer 104, the purification chamber 103 and the water tank 102 at a constant value (for example, not more than 2 MPa), the gas pressures in the PEM electrolyzer 104, the purification chamber 103 and the water tank 102 need to be controlled. Therefore, the pressure sensor 1027 is disposed in the water tank 102, the pressure sensor 1027 is electrically connected with the controller module 108, so that the pressure in the water tank 102 can be monitored in real time, and the cover can be automatically opened and closed by the controller module 108, if the pressure in the water tank 102 is detected to be too high (for example, more than 2 MPa), the controller module 108 can control the cover to be automatically opened to release the pressure in the water tank, so that the pressure in the water tank 102 is prevented from being too high, the phenomenon of bursting of the water tank 102 occurs, and after the pressure of the water tank 102 is released, the controller module 108 can also control the cover to be automatically closed.

In this embodiment, as shown in fig. 1 and 3, before the hydrogen generated by the water electrolysis in the PEM electrolyzer 104 enters the gas-water separator 106, the pressure of the hydrogen entering the gas-water separator 106 needs to be ensured, therefore, a first control valve 109, which is an automatic valve, is disposed on the pipeline where the hydrogen outlet 1041 communicates with the hydrogen inlet 1062, when the pressure of the hydrogen generated in the PEM electrolyzer 104 is not less than 2Mpa, the first control valve 109 will be automatically opened to enable the hydrogen to enter the gas-water separator 106, and when the pressure of the hydrogen is less than 2Mpa, the first control valve 109 will be closed, and of course, the first control valve 109 may also be manually opened.

In addition, as shown in fig. 3, a small amount of moisture and oxygen are added to the hydrogen generated by the water electrolysis in the PEM electrolyzer 104 during the process of entering the gas-water separator 106, so that the gas-water separator 106 is sequentially filled with a gas-water separation material 1066, a hydrogen drying material 1067 and a hydrogen impurity removal material 1068 from bottom to top, thereby ensuring that the hydrogen added through the hydrogenation gun 112 can reach the required purity. In addition, when the hydrotreater is continuously operated for a long time (more than or equal to 24 h), waste water exists in the gas-water separator 106, so that a third liquid level sensor 1064 is arranged outside the gas-water separator 106, and the third liquid level sensor 1064 is a high liquid level sensor, when the third liquid level sensor 1064 detects the water level in the gas-water separator 106, the waste water content in the gas-water separator 106 is too high, a third control valve 111 which is an automatic valve and is arranged at the pressure relief port 1061 is automatically started to release pressure and discharge water, so that redundant waste water is discharged to the outside of the shell 101 through the pressure relief port 1061, the pressure relief port is closed again after 30s, the service life of the gas-water separator 106 and the purity of hydrogen are improved, and the third control valve 111 can be opened manually.

In this embodiment, as shown in fig. 3, in order to ensure the purity and pressure of the hydrogen gas added to the solid hydrogen storage device, a hydrogen purity sensor 1065 is further disposed on the pipe of the gas-water separator 106 leading to the hydrogenation gun 112, and optionally, the hydrogen purity sensor 1065 also has a function of detecting the pressure. Specifically, a second control valve 110 with an automatic valve is disposed on a gas pipeline communicating the hydrogenation port 1063 with the hydrogenation gun 112, when the hydrogen purity sensor 1065 detects that the hydrogen pressure in the gas-water separator 106 reaches 2MPa and the hydrogen purity reaches 99.99%, the hydrogenation gun 112 is started, at this time, the second control valve 110 is automatically opened to hydrogenate the solid hydrogen storage device, when the hydrogen pressure in the gas-water separator 106 is less than 2MPa or the hydrogen purity is less than 99.99%, at this time, the hydrogenation gun 112 cannot be started, and the second control valve 110 is in a closed state, i.e. the hydrogenation machine is in a standby state. In addition, the hydrogenation guns used in the present embodiment can monitor the pressure of hydrogen gas injected into the solid-state hydrogen storage in real time to prevent the risk of explosion caused by excessive pressure of hydrogen gas injected into the solid-state hydrogen storage.

In addition, as shown in fig. 2, the water quality condition in the water tank 102 also affects the electrolysis efficiency, so that the water quality sensor 1023 is arranged in the water tank 102, and the water quality sensor 1023 is electrically connected with the controller module 108, so that the water quality condition in the water tank 102 can be monitored in real time; if it is detected that the total dissolved solids in the water is too high (e.g., TDS. Gtoreq.1), the controller module 108 will stop the electrolysis of the PEM electrolyzer 104 and issue a corresponding warning signal to prompt the operator to replace the water in the water tank, at which point the pressure sensor 1027, third control valve 111 and first control valve 109 are activated to release all pressure in the hydrogenation machine until the water in the water tank 102 is replaced, thereby ensuring good water quality entering the PEM electrolyzer 104.
