Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

Therefore, they should not be understood as limiting this application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0028] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] See also Figure 1 、 Figure 2 as well as Figure 3 The electrolytic water oxygen supply system for the hydrogen battery multifunctional cabin includes a water electrolysis device 10, a filtering mechanism 20, a purification mechanism 40, a purification mechanism 50 and a drying mechanism.

[0030] Among them, the electrolysis device 10 is used to electrolyze water to produce hydrogen and oxygen; the filtering mechanism 20 is used to filter the oxygen generated by the electrolysis device 10; the purification mechanism 40 has a purification chamber carrying a purification liquid, the purification liquid is hydrogen peroxide, the purification chamber is used to receive the filtered oxygen and purify it using the purification liquid; the purification mechanism 50 is used to receive and decompose hydrogen peroxide in the purified oxygen to output purified oxygen; the drying mechanism is used to dry the purified oxygen to a first preset humidity and control the temperature of the oxygen to a preset temperature.

[0031] Since oxygen comes from electrolyzed water, the impurities produced may be organic matter and dissolved ions in the raw water, as well as metal ions produced by electrode corrosion and organic fragments such as sulfonic acid groups that may be released by the proton exchange membrane (PEM). Therefore, there are organic matter and large-particle impurity ions in the impurities. Therefore, the use of the filtering mechanism 20 can not only physically remove large-particle organic matter and ions but also reduce some impurities to increase the purification rate of the subsequent purification liquid, and then use the purification liquid (high-purity hydrogen peroxide) to remove small-particle organic matter and small-particle metal ions through chemical reaction.

[0032] Among them, there may be a certain amount of hydrogen peroxide in the purified oxygen, so the purification mechanism 50 can be used to heat and decompose the hydrogen peroxide into oxygen and water. This not only improves the purity of the oxygen, but also hydrogen peroxide only produces water and oxygen during the reaction. Therefore, there is no need for additional humidification. It only needs to be dried later to obtain oxygen with a preset humidity to meet the oxygen humidity requirement.

[0033] The electrolytic water oxygen supply system for a hydrogen battery multifunctional cabin provided in the present application is arranged in sequence along the oxygen output direction through a filtering mechanism 20, a purification mechanism 40, a purification mechanism 50 and a drying mechanism. The oxygen generated by the electrolytic water device 10 can be filtered and impurity-removed, purified and impurity-removed, the purification liquid removed and dried in sequence. Without the need for an additional humidification mechanism, pure oxygen with a preset humidity and a first preset temperature can be obtained, which can effectively improve the utilization efficiency of oxygen while reducing costs.

[0034] In some optional embodiments, see Figure 1 、 Figure 2 as well as Figure 3 The filtering mechanism 20 includes a filter chamber, a filter screen 23, a scraper 22 and a driving mechanism. The air inlet of the filter chamber is connected to the oxygen outlet of the water electrolysis device 10. The filter screen 23 is detachably arranged at the air inlet of the filter chamber. The air outlet of the filter chamber is connected to the air inlet of the purification chamber. The scraper 22 is located in the filter chamber. The driving mechanism is transmission-connected to the scraper 22 to drive the scraper 22 to reciprocate along the filter screen 23.

[0035] See also Figure 2 as well as Figure 3 The filter cavity can be a cavity formed by a hollow pipe.

[0036] In order to facilitate the replacement of the filter screen 23, the pipe wall constituting the filter chamber may be provided with an opening and a cover for selectively closing the opening. The filter screen 23 may be output from the filter chamber through the opening, or the filter chamber may be connected by two sections of pipes and then detachably connected by means of a clamp, a hoop, etc., and the filter screen 23 is located at the joint.

[0037] The two sides of the filter screen 23 can be connected to the filter screen bracket 21 to support the filter screen 23, and it is also convenient to install it in the filter cavity.

[0038] The filter 23 is cleaned by the scraper 22, thereby improving the filtration quality on the basis of improving the operating efficiency of the electrolyzed water oxygen supply system for the hydrogen battery multifunctional cabin. At the same time, the filter 23 is detachably arranged in the filter cavity, which is also convenient for its replacement.

[0039] Exemplarily, the mesh size of the filter 23 is 2-5 mm, for example, 3 mm, which can block large particles of impurities while substantially not affecting the oxygen flow rate.

[0040] In order to prevent the filter 23 from being damaged by excessive air pressure, the pressure of oxygen on the filter 23 can be controlled to be maintained at 4.0 MPa or less during actual use.

[0041] In order to reduce the frequency of replacing the filter 23, the filter 23 may include a plurality of interconnected filter units 23, the area of ​​each filter unit 23 being greater than or equal to the size of the air inlet of the filter cavity, and the filter 23 being slidably disposed at the air inlet of the filter cavity so that when the filtering effect of one of the filter units 23 is poor, another filter unit 23 can be slidably replaced by sliding.

[0042] The filter screen 23 can be slidably arranged at the air inlet of the filter cavity in ways including but not limited to slots and guide rails. For details, please refer to relevant technologies and are not limited here.

[0043] The driving mechanism includes but is not limited to a telescopic rod, a micro cylinder or a motor. It can be understood that when a motor is used as the driving mechanism, a reversing mechanism needs to be configured between the driving mechanism and the scraper 22. The reversing mechanism is used to convert the received rotational motion and output it into reciprocating translation. For details, please refer to the relevant technology.

[0044] It should be noted that a filter screen 23 transport bracket, a flushing device 25 and a sewage pipe 24 can also be set. The flushing device 25 is used to flush the filter screen 23. The flushing device 25 may have a flushing chamber and a nozzle. The filter screen 23 transport bracket is used to transport the filter screen 23 into the flushing chamber. The sewage pipe 24 is connected to the flushing chamber for discharging the sewage after flushing.

[0045] When cleaning the flushing device 25, quantitative adjustment can be performed, that is, scraping is performed once or multiple times when the oxygen filtering flow is certain to increase the filtering amount and effective filtering time of the filter 23. When the system is not reacting, the filter 23 is transported to the flushing device 25 through the filter 23 transport bracket to flush the filter 23.

[0046] In some optional embodiments, see Figure 1 The air inlet of the filter chamber is connected to the oxygen outlet of the water electrolysis device 10 through an air pipe 101. The air pipe 101 is provided with a control valve 102, a first detection mechanism 103 and a first alarm mechanism (not shown). The first detection mechanism 103 includes a flow sensor. The first alarm mechanism is configured to trigger an alarm when the actual flow detected by the flow sensor exceeds a preset flow.

[0047] The preset flow rate refers to the rated flow rate of oxygen that the filter 23 and the scraper 22 can process without being damaged.

[0048] Through the above arrangement, when the oxygen flow detected by the first detection mechanism 103 exceeds the rated flow value processed by the filter 23 and the scraper 22, the alarm mechanism is triggered to alarm to notify relevant personnel that the system is overloaded. At the same time, the opening and closing degree of the control valve 102 can also be controlled to be reduced to reduce the oxygen flow.

[0049] In some optional embodiments, see Figure 1 The hydrogen battery multifunctional cabin electrolyzed water oxygen supply system further includes an atomizing mechanism 30, which is configured to atomize the filtered oxygen and deliver it to the purification chamber.

[0050] By atomizing the filtered oxygen and delivering it into the purification chamber, the contact area between the oxygen and the purification liquid is increased, thereby improving the purification efficiency.

[0051] Exemplarily, the atomizing mechanism 30 is an atomizing nozzle, which is disposed at the air inlet of the purification chamber. At the same time, for better purification, the air inlet of the purification chamber is lower than the air outlet of the purification chamber in the direction of gravity, so that the air inlet of the purification chamber is always submerged in the purification liquid. Exemplarily, the air inlet of the purification chamber is located on the bottom wall of the purification chamber, and the air outlet of the purification chamber is located on the top wall of the purification chamber.

[0052] The number of the atomizing nozzles can be one or more, and the air inlets of the purification chamber can be arranged in a one-to-one correspondence with the atomizing nozzles.

[0053] In some optional embodiments, see Figure 1 The purification mechanism 50 includes a purification chamber, a heating mechanism (not shown) and a hydrogen peroxide sensor 51.

[0054] The purification chamber is used to accommodate oxygen. The air inlet of the purification chamber is connected to the purification chamber via a first pipe 521, which is provided with a first valve 522. The air outlet of the purification chamber is connected to the drying mechanism via a second pipe 523, which is provided with a second valve 524. The heating mechanism is used to heat the temperature within the purification chamber to a temperature greater than or equal to the decomposition temperature of hydrogen peroxide. The hydrogen peroxide sensor 51 is used to measure the concentration of hydrogen peroxide in the purification chamber.

[0055] Exemplarily, the hydrogen peroxide sensor 51 is disposed in the second pipe 523 , and the hydrogen peroxide sensor 51 is located on a side of the second valve 524 close to the purification chamber.

[0056] With the above arrangement, the first valve 522 and the second valve 524 can be closed first, and the temperature in the purification chamber can be heated by the heating mechanism to a temperature greater than or equal to the decomposition temperature of hydrogen peroxide, thereby decomposing the hydrogen peroxide entering the purification chamber. When the hydrogen peroxide sensor 51 detects that the actual concentration of hydrogen peroxide in the purification chamber is less than or equal to a preset concentration (oxygen less than the preset concentration is regarded as purified oxygen), the second valve 524 can be opened to deliver the purified oxygen to the drying mechanism.

[0057] In some optional embodiments, see Figure 1 The drying mechanism includes a high-temperature and high-pressure drying device 62 , a condensation drying device 63 and a conduit 64 .

[0058] The high-temperature and high-pressure drying device 62 has a high-temperature and high-pressure reaction chamber, which is configured to receive part of the purified oxygen. The high-temperature and high-pressure drying device 62 is used to dry the oxygen to a second preset humidity by high-temperature and high-pressure drying.

[0059] The condensation and drying device 63 is configured to receive the remaining purified oxygen and is used to freeze-dry the oxygen to a third preset humidity.

[0060] The conduit 64 is respectively connected to the air outlet of the high-temperature and high-pressure drying device 62 and the air outlet of the condensation drying device 63 to obtain oxygen with a first preset humidity and a preset temperature.

[0061] Among them, the high-temperature and high-pressure drying device 62 and the condensation drying device 63 can be directly purchased on the market.

[0062] It is understood that the high-temperature, high-pressure drying device 62 includes a heating mechanism and a pressurizing mechanism. The heating mechanism is used to heat the high-temperature, high-pressure reaction chamber, and the pressurizing mechanism is used to pressurize the high-temperature, high-pressure reaction chamber, thereby achieving high-temperature, high-pressure drying of the oxygen in the high-temperature, high-pressure reaction chamber to a second preset humidity. The condensing device is used to condense and dry the remaining purified oxygen.

[0063] By diverting the oxygen and drying it separately in the high-temperature and high-pressure drying device 62 and the condensation drying device 63 and then converging them, not only can the oxygen dried by the high-temperature and high-pressure drying device 62 be urgently input when the temperature is too high to avoid high-temperature damage, but it can also provide a certain proportion of low-temperature oxygen to combine with the high-temperature oxygen dried by the high-temperature and high-pressure drying device 62 to lower the temperature and form oxygen at a preset temperature (30-42°C), thereby avoiding the oxygen temperature being too high and causing a decrease in oxygen activity, which may cause oxygen poisoning to the people in the multi-functional cabin, and avoiding the oxygen temperature being too low and causing a decrease in the oxygen content in the body of the people in the multi-functional cabin, leading to hypoxia.

[0064] Among them, the proportion of oxygen delivered to the high-temperature and high-pressure drying device 62 and the condensation drying device 63 should be selected during actual debugging based on the oxygen temperature output by the high-temperature and high-pressure drying device 62 and the condensation drying device 63 and the preset temperature of the oxygen output after final mixing.

[0065] In some optional embodiments, a first desiccant is provided in the high-temperature and high-pressure reaction chamber, and the first desiccant includes at least one of silica gel, aluminum oxide, and calcium oxide.

[0066] Among them, the first desiccant can be selected according to the temperature and pressure of the high-temperature and high-pressure reaction. For example, silica gel can be used when the temperature is 100-120°C (regeneration is required above 120°C). At ultra-high temperatures, activated alumina and calcium oxide and other desiccants with good drying effects at high temperatures can be used to reduce the purchase and transportation costs increased by the first catalyst to better meet the usage conditions in high-altitude and cold areas.

[0067] Reference may be made to related technologies to determine the overall drying efficiency of the desiccant based on the selected first desiccant component and the temperature and pressure of the high-temperature and high-pressure drying reaction, and then determine the humidity of the oxygen after the high-temperature and high-pressure drying based on the oxygen flow rate. Alternatively, a humidity sensor may be provided at the outlet of the high-temperature and high-pressure reaction chamber to obtain the humidity of the oxygen after the high-temperature and high-pressure drying.

[0068] In some optional embodiments, a second desiccant is provided in the condensation chamber, and the second desiccant includes at least one of molecular sieve and silica gel.

[0069] By providing a second desiccant in the condensing chamber, the drying efficiency can be improved.

[0070] Among them, condensed water can be extracted during condensation drying. At this time, relevant technologies can be referred to, and the humidity can be predicted based on the drying efficiency of the second desiccant and the degree of extraction of condensed water combined with the flow rate of oxygen, which is conducive to obtaining oxygen with a first preset humidity; a humidity sensor can also be provided at the air outlet of the condensation chamber to obtain the humidity of the oxygen after condensation drying.

[0071] In some optional embodiments, see Figure 1 The manifold 64 has a main pipe 640 for outputting oxygen, and a third pipe 642 and a fourth pipe 644 respectively connected to the main pipe 640. The third pipe 642 is used to transport oxygen to the filtering mechanism 20, and the third pipe 642 is provided with a third valve 643. The fourth pipe 644 is used to output oxygen, and the fourth pipe 644 is provided with a fourth valve 645. The main pipe 640 is connected to a second detection mechanism 641, which includes a temperature sensor, a humidity sensor and an oxygen purity analyzer.

[0072] It is understandable that the third valve 643 and the fourth valve 645 are normally closed.

[0073] The temperature, humidity and purity of the oxygen at the output end can be detected and obtained through the second detection mechanism 641. If the usage requirements are met, the fourth valve 645 can be opened to improve the efficiency of oxygen use. If the requirements are not met, the third valve 643 can be opened to re-process the oxygen.

[0074] It is understandable that the first detection mechanism 103 and the second detection mechanism 641 can be integrated together to form a detection mechanism 70 to improve space occupancy.

[0075] It is understandable that the gas delivery end of the fourth pipeline 644 can directly deliver oxygen to the hydrogen battery multifunctional cabin, or the gas delivery end of the fourth pipeline 644 can be connected to a storage facility to store oxygen according to actual needs.

[0076] In some optional embodiments, the electrolyzed water oxygen supply system for the hydrogen battery multifunctional cabin also includes a second alarm mechanism (not shown), which is respectively connected to the temperature sensor, humidity sensor and oxygen purity analyzer. The second alarm mechanism is configured to alarm when any detection result of the temperature sensor, humidity sensor and oxygen purity analyzer does not meet the preset value.

[0077] By setting the alarm mechanism, an alarm can be issued when any of the temperature, humidity and purity of the oxygen at the output end does not meet the use requirements, so that the user can take relevant measures in time.

[0078] In some optional embodiments, the electrolyzed water oxygen supply system for the hydrogen battery multifunctional cabin also includes an adsorption drying mechanism 61, which includes an adsorption chamber and a third desiccant located in the adsorption chamber. The air inlet of the adsorption chamber is used to receive purified oxygen, and the air outlet of the adsorption chamber is respectively connected to the high-temperature and high-pressure drying device 62 and the condensation drying device 63.

[0079] The third desiccant includes at least one of activated alumina, silica gel, molecular sieve, anhydrous magnesium sulfate, activated carbon, anhydrous calcium chloride, soda lime, solid caustic soda, anhydrous copper sulfate, phosphorus pentoxide, and calcium sulfate.

[0080] Among them, reference can be made to relevant technologies, and the drying efficiency can be inferred based on the third desiccant and its reaction time, and the humidity can be predicted in combination with the oxygen flow rate. A humidity sensor can also be provided at the air outlet of the adsorption chamber to obtain the oxygen humidity after adsorption and drying.

[0081] The adsorption drying mechanism 61 uses the third desiccant to adsorb and dry the purified oxygen to remove part of the moisture, which is beneficial to improving the drying efficiency of the high-temperature and high-pressure drying device 62 and the condensation drying device 63 and reducing the energy consumption of the high-temperature and high-pressure drying device 62 and the condensation drying device 63.

[0082] For example, the waste heat generated by the high-temperature and high-pressure drying device 62 may be transferred to the adsorption drying mechanism 61 to improve the drying efficiency of the adsorption drying mechanism 61 .

[0083] The electrolytic water oxygen supply system for the hydrogen battery multifunctional cabin further includes a desiccant storage box 60, which is used to store spare desiccants for replacing the desiccants in the electrolytic water oxygen supply system for the hydrogen battery multifunctional cabin.

[0084] The present application also provides a method for post-processing oxygen using the above-mentioned hydrogen battery multifunctional cabin electrolysis water oxygen supply system, which includes: using a filtering mechanism 20 to filter the oxygen generated by the electrolysis water device 10, purifying the filtered oxygen through a purification liquid, purifying the purified oxygen through a purification mechanism 50, and drying the purified oxygen to a first preset humidity and a preset temperature by a drying mechanism, the preset temperature being 30-42°C.

[0085] The oxygen post-processing method of the electrolytic water oxygen supply system for the hydrogen battery multifunctional cabin adopted in the present application is simple to operate and controllable, and can filter and remove impurities, purify and remove impurities, remove the purification liquid and dry the oxygen generated by the electrolytic water device 10 in sequence. Without the need to introduce an additional humidification mechanism, pure oxygen with a preset humidity and a first preset temperature can be obtained, which can effectively improve the utilization efficiency of oxygen while reducing costs.

[0086] In summary, the electrolytic water oxygen supply system and oxygen post-processing method for the hydrogen battery multifunctional cabin can improve the purity, humidity and temperature of the oxygen provided by the electrolytic water oxygen supply system for the hydrogen battery multifunctional cabin, and can effectively improve the utilization efficiency of oxygen while reducing costs.

[0087] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
