The process of testing the optimal hydrogen charging and discharging parameters by utilizing the magnesium-based solid hydrogen storage material performance testing system comprises the following steps:
(1) when charging, in a hydrogen system: the hydrogen of the hydrogen source 1 is introduced into the system, the hydrogen flow rate measured by the flow detection member 6 is observed, the hydrogen flow rate is adjusted by the first flow adjustment member 3 to reach the preset hydrogen absorption flow rate, and then the hydrogen is introduced into the storage cavity of the heat exchange member 12. In a hot oil system: the circulation means 13 and the second flow rate adjustment means 16 are opened to circulate the hot oil between the heat exchange means 12 and the heating means 14, the opening degree of the second flow rate adjustment means 16 is adjusted to control the flow rate of the hot oil to a set value, and then the heating means 14 heats the hot oil, and when the temperature detected by the temperature detection means 11 reaches the hydrogen absorption temperature, the hydrogen absorption of the hydrogen storage material is started.
Since heat is released in the charged state, when the temperature detected by the observation temperature detecting means 11 is higher than the set maximum temperature, the cooling means 15 is turned on to cool down the hot oil.
During the hydrogen charging process, whether the pressure detected by the pressure detection component 10 drops too fast is observed, if the hydrogen flow is too large, the first flow regulation component 3 is adjusted to reach the pressure balance of the storage cavity in the heat exchange component 12.
After the charging mass of the flow rate detection means 6 reaches the set value, the heating means 14, the cooling means 15, the circulation means 13, the second flow rate adjustment means 16, and the hydrogen source 1 are turned off, and the charging is completed.
(2) After entering the hydrogen discharge state, in the hot oil system: and opening the circulating member 13 and the second flow regulating member 16 to circulate the hot oil between the heat exchange member 12 and the heating member 14, regulating the opening degree of the second flow regulating member 16, controlling the flow of the hot oil to reach a set value, heating the hot oil by the heating member 14, and setting the temperature required by the chemical reaction of the materials in the heat exchange member 12. When the temperature of the temperature detecting member 11 reaches the hydrogen discharge temperature, the hydrogen gas is discharged from the heat exchange member 12 containing the hydrogen storage material and finally is led to the device to be charged 5, which is not limited to the device to be charged 5, but may be a storage container. After the hydrogen discharge quality detected by the flow detection component 6 reaches the set value (note that the experiment aim is not only to measure the maximum hydrogen discharge amount, but also to measure the maximum hydrogen discharge efficiency under the corresponding test conditions, and the maximum time for which the maximum efficiency lasts, such as the maximum hydrogen discharge efficiency and the maximum time for which the maximum efficiency lasts, often appears in the test process of discharging 90% of the total amount of hydrogen, so we will focus on the test process of discharging 90% of the total amount of hydrogen, in the process, the data such as temperature, pressure and flow rate corresponding to the maximum hydrogen discharge efficiency can be found according to the measured data, and the time spent on discharging the remaining 10% of the total amount of hydrogen in the later period is long and the research significance is not large, so it is not necessary to discharge the remaining 10% of the total amount of hydrogen, so a set value is set for the flow detection component 6 to control the timing of cutting off with the hydrogen charging equipment 5), the heating member 14, the circulating member 13, and the second flow rate adjusting member 16 are turned off, and the communication with the apparatus to be charged 5 is cut off, and the hydrogen discharge is ended.
Therefore, the system can completely test two processes of hydrogen charging and hydrogen discharging of the hydrogen storage material, particularly the magnesium alloy hydrogen storage material, and finally obtain the optimal hydrogen charging and discharging parameters, specifically, parameters such as hydrogen pressure, hydrogen flow, heat transfer oil temperature, heat transfer oil flow and actual reaction temperature of the hydrogen storage material in the hydrogen charging process and the hydrogen discharging process can be controlled, so that a corresponding environment is provided for experimental requirements, the parameters can be detected constantly by using corresponding equipment, a data curve is recorded for experimental analysis, and further the optimal hydrogen charging and discharging parameters are finally obtained, thereby laying a solid foundation for researching the properties and characteristics of the magnesium alloy solid hydrogen storage material.
In this embodiment, preferably, as shown in fig. 1, the gas inlet path communicating between the inlet end of the storage chamber and the hydrogen gas source 1 includes a first hydrogen inlet path and a second hydrogen inlet path communicating in sequence, the inlet end of the first hydrogen inlet path communicating with the hydrogen gas source 1, and the outlet end of the second hydrogen inlet path communicating with the inlet end of the storage chamber;

wherein the inlet end of the storage chamber coincides with the outlet end of the storage chamber, and the second hydrogen inlet path and the first hydrogen outlet path coincide to form a common path.
As can be seen from the above-described structure, when filling hydrogen gas, the hydrogen gas can be transported to the storage chamber of the heat exchange member 12 through the first hydrogen inlet path and the second hydrogen inlet path in sequence; when discharging hydrogen gas, the hydrogen gas generated in the heat exchange member 12 may be discharged to the device to be charged 5 through the first hydrogen discharge path and the second hydrogen discharge path in sequence. Wherein the second hydrogen intake path and the first hydrogen discharge path are overlapped to form a common path, which can save the piping, and in addition, the second flow rate detection member 6 described below can be saved, reducing the cost.
In this embodiment, preferably, as shown in fig. 1, the first hydrogen intake path is provided with a first control valve 2 and a first flow rate regulation member 3 in this order, and the first control valve 2 is provided near the hydrogen source 1 side.

Further, preferably, as shown in fig. 1, the second control valve 7 is also connected in parallel with a third control valve 8;
a first filter is arranged on a path of the second control valve 7 connected with the third control valve 8 in parallel, and the first filter is arranged close to one side of the cooling unit 9;
a second filter is arranged on a path of the third control valve 8 connected in parallel with the second control valve 7, and the second filter is arranged close to one side of the flow detection member 6;
the second exhaust hydrogen path is provided with a fourth control valve 4.
According to the above-described structure, during hydrogenation, the second control valve 7 is opened, the third control valve 8 and the fourth control valve 4 are both in a closed state, and hydrogen gas sequentially passes through the first hydrogen inlet path, the second control valve 7, the first filter, the cooling unit 9 and the pressure detection member 10 and enters the storage cavity of the heat exchange member 12, wherein the first filter plays a role in filtering impurities in the hydrogen gas.
When hydrogen is discharged, the first control valve 2 and the second control valve 7 are both in a closed state, the third control valve 8 and the fourth control valve 4 are opened, and the hydrogen generated in the heat exchange member 12 finally flows into the equipment to be inflated through the pressure detection member 10, the cooling unit 9, the third control valve 8 and the second filter in sequence. The cooling unit 9 plays a role in cooling high-temperature hydrogen, so that damage to other parts in a hydrogen discharge path and the equipment 5 to be charged can be effectively avoided, and the use safety can be ensured; the second filter plays a role in filtering hydrogen, and the purity of the hydrogen is ensured.
The above mentioned filters are unidirectional, so the first filter is arranged close to the cooling unit 9 side with respect to the second control valve 7 for filtering the hydrogen gas during charging, and the second filter is arranged close to the flow detection member 6 side with respect to the third control valve 8 for filtering the hydrogen gas during discharging.
In this embodiment, the cooling member 15 is preferably a cooling fan, which has good cooling effect and low cost, and helps to reduce the cost.

The pressure detecting member 10 is a pressure transmitter capable of accurately detecting the pressure of hydrogen intake and the pressure of hydrogen discharge.
The temperature detection component 11 is a temperature transmitter, and can accurately detect the temperature of the storage cavity of the heat exchange component 12.
In summary, the process of testing the optimum hydrogen charging and discharging parameters by the magnesium-based solid hydrogen storage material performance testing system is described in conjunction with the detailed components mentioned above as follows:
when charging, in a hydrogen system: the third control valve 8 and the fourth control valve 4 are in a closed state, the first control valve 2 is opened, the hydrogen provided by the hydrogen source 1 is introduced into the system, the hydrogen flow rate measured by the flow detection component 6 is observed, the first flow regulation component 3 is used for regulating the hydrogen flow rate to achieve a preset hydrogen absorption flow rate, and the second control valve 7 is opened, so that the hydrogen with a fixed flow rate finally enters the storage cavity of the heat exchange component 12 through the cooling unit 9. In a hot oil system: the circulation member 13 and the second flow rate adjustment member 16 are opened to circulate the hot oil between the heat exchange member 12 and the heating member 14, the opening degree of the second flow rate adjustment member 16 is adjusted to control the flow rate of the hot oil to reach a set value, then the heating member 14 is enabled to heat the hot oil, and when the temperature of the temperature detection member 11 reaches the hydrogen absorption temperature, the hydrogen storage material starts to absorb hydrogen.
Since heat is released in the charged state, when the temperature detected by the observation temperature detecting means 11 is higher than the set maximum temperature, the cooling means 15 is turned on to cool down the hot oil. During the hydrogen charging process, whether the pressure detected by the pressure detection component 10 drops too fast is observed, if the hydrogen flow is too large, the first flow regulation component 3 is adjusted to reach the pressure balance of the storage cavity in the heat exchange component 12. After the hydrogen charge mass of the flow rate detection means 6 reaches the set value, the heating means 14, the cooling means 15, the circulation means 13, the second flow rate adjustment means 16, the first control valve 2, and the second control valve 7 are closed, and the hydrogen charge is completed.
After entering the hydrogen release state, in the hydrogen system, the first control valve 2 and the second control valve 7 are both closed, and the third control valve 8 and the fourth control valve 4 are both opened. In a hot oil system: and opening the circulating member 13 and the second flow regulating member 16 to circulate the hot oil between the heat exchange member 12 and the heating member 14, regulating the opening degree of the second flow regulating member 16, controlling the flow of the hot oil to reach a set value, heating the hot oil by the heating member 14, and setting the temperature required by the chemical reaction of the materials in the heat exchange member 12. When the temperature of the temperature detection component 11 reaches the hydrogen discharge temperature, hydrogen gas is discharged from the heat exchange component 12 filled with the hydrogen storage material, the high-temperature hydrogen gas discharged from the heat exchange component 12 is cooled to normal temperature through the water chiller, and the high-temperature hydrogen gas passes through the third control valve 8, the flow detection component 6 and the fourth control valve 4 and then is led to the equipment to be charged with hydrogen 5, such as a fuel cell or other hydrogen-using equipment, and is easy to be or is a storage container. When the hydrogen release mass detected by the flow rate detecting means 6 reaches the set value, the heating means 14, the circulating means 13, the second flow rate adjusting means 16, the third control valve 8, and the fourth control valve 4 are closed, and the hydrogen release is completed.
The two processes of hydrogen charging and hydrogen discharging of the hydrogen storage material, particularly the magnesium alloy hydrogen storage material, can be mastered through the test process, and the optimal hydrogen charging and discharging parameters can be obtained finally.
