[0002] With the global industrialization process accelerating, the consumption of primary fossil energy fuel is increasing, and the pollution to the environment is also becoming more and more serious, so it is urgent to find a clean fuel as a substitute. Hydrogen energy, as a kind of high-efficiency, clean, low-carbon, environmental protection and sustainable development secondary energy, is regarded as the most potential clean energy. Hydrogen energy, as the inevitable direction of new energy power automobile, is one of the ideal solutions to replace oil fuel. In addition to higher requirements on purity, the control of trace impurities in hydrogen is more important, otherwise it will seriously affect the operation efficiency and service life of the battery.

[0040] Example 1

[0041] like Figures 1-7 As shown, this embodiment discloses an apparatus for timed and quantitative absorption of inorganic halides in hydrogen gas, including a housing 1. The housing 1 is equipped with an absorption tank 2, a liquid addition device 3, and a gas inlet device 4. The liquid addition device 3 is connected to the absorption tank 2 through a first pipe 5 to add a dissolving liquid. The gas inlet device 4 is connected to the absorption tank 2 through a second pipe 6 to introduce the gas to be absorbed into the dissolving liquid in the absorption tank 2 to form an absorption liquid. The absorption tank 2 is also connected to a pressurizing device through a third pipe 7. The second pipe 6 is also connected to a collection pipe 9 for collecting the absorption liquid through a first three-way valve 8.

[0042] It also includes a control system, which is electrically connected to the liquid dispensing device 3 and the air intake device 4.

[0043] During operation, the system first performs a rinse, then turns on the liquid addition device 3 and injects sodium hydroxide solution into the absorption tank 2 through the first pipe 5. Then, it turns on the gas inlet device 4 and injects the hydrogen to be absorbed into the sodium hydroxide solution through the second pipe 6. When the sodium hydroxide solution absorbs the inorganic halides of the hydrogen to be absorbed for a set time, it turns on the pressurization device and injects high-pressure nitrogen into the top of the absorption tank 2 through the third pipe 7. Since the absorption tank 2 is sealed, the high pressure inside the absorption tank 2 forces the saturated sodium hydroxide solution towards the collection liquid pipe 11 and into the collector. By detecting the saturated sodium hydroxide solution in the collector, analytical data of inorganic halides and other substances can be obtained.

[0044] When the rinse is carried out, the liquid adding device 3 is opened first, then the first pipeline 5 is used to inject the sodium hydroxide solution (15-25 mL) into the absorption tank 2, so that the sodium hydroxide solution flushes the absorption tank 2; then the pressurizing device is opened, the high-pressure nitrogen is injected into the top of the absorption tank 2 through the third pipeline 7, because the absorption tank 2 is in a sealed state, the high pressure in the absorption tank 2 presses the rinsed sodium hydroxide solution to the waste liquid pipeline 12 and flows into the waste liquid tank; and the circulation and repeated flushing are discharged for 3 times; finally, the gas inlet device 4 is opened, the second pipeline 6 is used to inject the hydrogen to be absorbed into the absorption tank 2, the hydrogen absorbed by the absorption tank 2 is discharged through the exhaust pipeline 15, so that the mixed gas is prevented from participating in the measurement, and the error of the saturated sodium hydroxide to be detected during the detection is prevented.

[0045] Specifically, the hydrogen inorganic halide is efficiently absorbed through the modular design; the liquid adding device 3 and the gas inlet device 4 provided in the system ensure the sufficient reaction of the dissolved liquid and the gas to be measured; through the cooperation of the multi-pipeline system and the control system, the operation steps are simplified, the automation, the absorption rate, the absorption time, the accuracy and the efficiency are significantly improved.

At this time, the liquid enters the collecting liquid pipeline 11 through the collecting pipeline 9 and flows into the collector for storage;

[0049] After the target liquid is collected, if waste liquid is generated, the second three-way valve 10 can be adjusted to the state of communicating with the waste liquid pipeline 12, and the passage of the collecting liquid pipeline 11 is closed at the same time, the waste liquid is guided into the waste liquid tank for discharge or treatment through the waste liquid pipeline 12, the efficient control of the separation of the target liquid and the waste liquid is realized, the problem of liquid mixing is avoided, the precision of liquid collection and the convenience of waste liquid treatment are improved, and the device is suitable for various liquid treatment scenes.

[0051] The enclosure 1 is equipped with a display screen 16 on the outside, and the control system is electrically connected to the pressurization equipment and the display screen 16.

[0052] When pressurization is required, the control system is activated, and the pressurization equipment is operated through its circuit. Then, the third three-way valve 13 is operated to connect the pressurization pipeline 14 with the third pipeline 7, while the exhaust pipeline 15 is closed. At this time, the pressurization equipment applies pressure to the third pipeline 7 through the pressurization pipeline 14 to meet the needs of liquid or gas processing.

[0053] When the process is complete and the gas in the third pipe 7 needs to be discharged, the passage of the pressurized pipe 14 is closed by adjusting the third three-way valve 13, and the connection between the exhaust pipe 15 and the third pipe 7 is opened at the same time.

[0054] The gas in the third pipe 7 is discharged to the outside through the exhaust pipe 15, completing the exhaust operation.

[0055] Specifically, the display screen 16 is electrically connected to the control system and can display information such as method parameters, real-time flow rate of the gas being measured, and operating status in real time.
