Description

Technical Field

[0001] This invention relates to the field of hydrogen production and dissolution methods, and particularly to a hydrogen production and dissolution system and method. Background Technology

[0002] Hydrogen energy is a clean, efficient, and renewable energy source. One developing application technology is the dissolution of hydrogen in water to create hydrogen-rich water. Hydrogen-rich water not only possesses unique health benefits but also demonstrates significant application potential in water purification and wastewater treatment. Traditional hydrogen production technologies mainly include water electrolysis and fossil fuel-based hydrogen production. In practice, water electrolysis is more common. Traditional water electrolysis typically relies on core equipment such as electrolyzers and collection tanks. The electrolyzer decomposes water into hydrogen and oxygen, while the collection tank stores the produced hydrogen. However, when hydrogen is needed for use, it requires transportation and dissolution in water using specific equipment or technologies. This process faces several challenges. First, traditional production technologies require transporting hydrogen from the electrolyzer to the dissolution equipment, a process involving multiple steps and equipment, increasing operational complexity and potentially leading to hydrogen loss during transport. Second, hydrogen is a highly flammable and explosive gas, posing potential safety hazards during storage and transfer. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a hydrogen production and dissolution system that can directly dissolve the produced hydrogen in water, thereby saving storage and transportation equipment and reducing safety hazards.

[0004] To address the aforementioned technical problems, the present invention provides a hydrogen production and dissolution system, comprising a power supply component, an electrolysis component, a processing component, a reaction component, and a safety component. The power supply component is electrically connected to an external power source. The electrolysis component includes a water tank, an electrolyzer, and a pump. The water tank is connected to the pump, the pump is connected to the electrolyzer, and the electrolyzer is electrically connected to the power supply component.

[0005] The processing component includes a gas-liquid separator connected to the electrolyzer. The reaction component includes a booster and a reaction vessel. One end of the booster is connected to the gas-liquid separator, and the other end is connected to the reaction vessel. The booster pressurizes the reaction vessel. An ultrasonic generator is installed inside the reaction vessel. The safety component includes a leak sensor located on the side of the reaction vessel.

[0006] As an improvement to the above solution, the electrolysis assembly further includes a chiller unit, the pump is located below the water tank, the input end of the pump is connected to the water tank, the output end of the pump is connected to the inlet of the chiller unit, and the outlet of the chiller unit is connected to the electrolyzer.

[0007] As an improvement to the above solution, the electrolyzer includes a water inlet, a hydrogen outlet, an oxygen outlet, a negative electrode connection port, and a positive electrode connection port. The water inlet is connected to an external chiller unit, the hydrogen outlet is connected to the gas-liquid separator, the oxygen outlet is connected to the water tank, and the negative electrode connection port and the positive electrode connection port are respectively connected to the electrodes of the power supply component.

[0008] As an improvement to the above solution, the processing assembly further includes a purifier, a cooling chamber, and a precision filter. The gas-liquid separator includes a hydrogen outlet, which is connected to the inlet of the purifier, and the purifier is connected to an external heat source. One end of the cooling chamber is connected to the outlet of the purifier, and the other end of the cooling chamber is connected to the booster. The cooling chamber is connected to an external cooling device. The precision filter is located between the gas-liquid separator and the purifier, and between the purifier and the cooling chamber.

[0009] As an improvement to the above solution, the gas-liquid separator is connected to an external cooling device, and the gas-liquid separator also includes a liquid outlet, which is connected to the bottom of the water tank.

[0010] As an improvement to the above scheme, the number of reaction vessels is multiple and they are arranged at an angle. The angle between the center line of the reaction vessel and the horizontal plane is in the range of 40°-50°. An electromagnetic valve is provided between the booster and each of the reaction vessels.

[0011] The present invention also provides a method for producing and dissolving hydrogen, applied to the hydrogen production and dissolving system described above, comprising the following steps:

[0012] a) Real-time monitoring of water level and temperature in the water tank. When the water level in the water tank rises to the preset water level value and the water temperature reaches the preset water temperature value, the pump is started.

[0013] b) Start the electrolyzer to electrolyze the water, monitor the hydrogen flow rate in real time, and start the booster to pressurize the reaction tank after the hydrogen flow rate reaches the preset value.

[0014] c) Real-time monitoring of the pressure inside the reaction vessel. When the pressure inside the vessel reaches the preset reaction pressure value, the ultrasonic generator is activated to maintain the pressure in the reaction vessel and start timing. When the time reaches the preset reaction time value, the ultrasonic generator and the pressure booster are turned off and the pressure in the reaction vessel is released.

[0015] As an improvement to the above solution, the following steps are also included:

[0016] The water temperature in the water tank is controlled by a chiller unit to ensure that the water temperature reaches the preset value and remains within the preset range.

[0017] After the electrolyzer is started to electrolyze water to produce hydrogen, the hydrogen first passes through a gas-liquid separator for gas-liquid separation. The liquid level in the gas-liquid separator is monitored in real time. Once the liquid level reaches the preset value, the liquid in the gas-liquid separator is introduced into the water tank.

[0018] The hydrogen gas exiting the gas-liquid separator first enters the purifier for purification. During the purification process, an external heat source is used to heat the purifier. After heating to the set purification temperature, the temperature is maintained. The purified hydrogen gas then enters the cooling chamber, where an external cooling device cools the hydrogen gas. Once the hydrogen gas temperature drops to the preset cooling temperature, it is introduced into the reaction vessel.

[0019] As an improvement to the above solution, the following steps are also included:

[0020] The booster is connected to multiple reaction vessels, which alternately perform pressurization, pressure holding, and pressure release.

[0021] After the previous reaction vessel has completed pressurization, pressure holding and pressure release in sequence, the next reaction vessel will start pressurization, pressure holding and pressure release in sequence.

[0022] Before the current reaction vessel completes pressurization, pressure holding, and pressure release, the solenoid valves corresponding to the other reaction vessels are closed; after the current reaction vessel completes pressurization, pressure holding, and pressure release, the solenoid valve corresponding to that reaction vessel is closed, and the solenoid valve corresponding to the next reaction vessel is opened.

[0023] As an improvement to the above scheme, the preset water temperature is between 20℃ and 28℃, and the preset reaction pressure and reaction time of each reaction tank can be set independently, with the preset reaction pressure between 1.5MPa and 2.5MPa.

[0024] Implementing this invention has the following beneficial effects:

[0025] The hydrogen production and dissolution system of this invention includes a power supply component, an electrolysis component, a processing component, a reaction component, and a safety component. The electrolysis component includes a water tank, an electrolyzer, and a pump. The pump pumps water from the water tank into the electrolyzer, where the water is electrolyzed. The processing component includes a gas-liquid separator connected to the electrolyzer. The reaction component includes a pressure booster and a reaction tank. The pressure booster pressurizes the reaction tank, which contains an ultrasonic generator capable of generating ultrasonic waves. Hydrogen gas generated in the electrolyzer is introduced into the gas-liquid separator for gas-liquid separation. The pure hydrogen produced by separation can be directly introduced into the reaction vessel through the pressurizer. The pressurizer can pressurize the reaction vessel to form a high-pressure container. Under the ultrasonic vibration generated by the ultrasonic generator, the hydrogen quickly dissolves into water in the high-pressure container. Therefore, in this invention, the produced hydrogen can be directly dissolved in water, saving storage and transportation equipment, avoiding leakage of hydrogen during storage and re-transport, and reducing safety hazards. At the same time, the safety component includes a leakage sensor located on the side of the reaction vessel, which can continuously monitor the system, making it safer. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0032] See Figure 1This invention discloses a hydrogen production and dissolution system, including a power supply component 1, an electrolysis component 3, a processing component 4, a reaction component 5, and a safety component 2. The power supply component 1 is electrically connected to an external power source to supply power to the electrolysis component 3, the processing component 4, the reaction component 5, and the safety component 2. The electrolysis component 3 includes a water tank 31, an electrolyzer 32, and a pump 33. The water tank 31 contains water for electrolysis and can be replenished from an external water source. The water tank 31 is connected to the pump 33, which is also connected to the electrolyzer 32. The pump 33 pumps the water from the water tank 31 into the electrolyzer 32. The electrolyzer 32 is electrically connected to the power supply component 1 and electrolyzes the pumped water to produce hydrogen and oxygen. The pump 33 is preferably a water pump.

[0033] The processing component 4 is used to process the produced hydrogen gas to obtain hydrogen gas with higher purity and suitable for dissolution. The processing component 4 includes a gas-liquid separator 41, which is connected to the electrolyzer 32. Since the produced hydrogen gas will have a small amount of liquid attached, in order to purify the hydrogen gas, the produced hydrogen gas enters the gas-liquid separator 41. The liquid is condensed and discharged in the gas-liquid separator 41, and the remaining hydrogen gas is introduced into the reaction component 5. The reaction component 5 includes a booster 51 and a reaction tank 52. One end of the booster 51 is connected to the gas-liquid separator 41, and the other end of the booster 51 is connected to the reaction tank 52. Hydrogen gas discharged from the liquid separator 41 enters the reaction tank 52 through the booster 51. The reaction tank 52 is filled with pure water. The booster 51 pressurizes the reaction tank 52, making it a high-pressure container. An ultrasonic generator 521 is installed inside the reaction tank 52. The ultrasonic generator 521 can promote the dissolution and diffusion of hydrogen molecules by generating high-frequency vibration waves, thereby accelerating the dissolution of hydrogen in water to form hydrogen-rich water. In this process, there is no need to store hydrogen or build a conveying device between the storage container and the reaction container; the hydrogen produced by electrolysis can directly undergo the hydrogen dissolution reaction, thus saving on storage and transportation equipment. In addition, the safety component 2 includes a leak sensor 21, which is located on the side of the reaction tank 52. The leak sensor 21 can detect the area around the reaction tank 52. Once a hydrogen leak is detected, the system will be shut down to prevent accidents, thereby further improving safety.

[0034] The beneficial effects of the embodiments of the present invention are as follows:

[0035] This invention provides a hydrogen production and dissolution system comprising a power supply component 1, an electrolysis component 3, a processing component 4, a reaction component 5, and a safety component 2. The electrolysis component 3 includes a water tank 31, an electrolyzer 32, and a pump 33. The pump 33 pumps water from the water tank 31 into the electrolyzer 32, where the water is electrolyzed. The processing component 4 includes a gas-liquid separator 41 connected to the electrolyzer 32. The reaction component 5 includes a pressure booster 51 and a reaction tank 52. The pressure booster 51 pressurizes the reaction tank 52, which contains an ultrasonic generator 521 capable of generating ultrasonic waves. Hydrogen produced within the electrolyzer 32... Gas is introduced into the gas-liquid separator 41 for gas-liquid separation. The generated pure hydrogen can be directly introduced into the reaction tank 52 through the booster 51. The booster 51 can pressurize the reaction tank 52 to form a high-pressure container. Under the ultrasonic vibration generated by the ultrasonic generator 521, the hydrogen quickly dissolves into water in the high-pressure container. Therefore, in this invention, the produced hydrogen can be directly dissolved in water, saving storage and transportation equipment, avoiding leakage of hydrogen during storage and re-transportation, and reducing safety hazards. At the same time, the safety component 2 includes a leakage sensor 21, which is located on the side of the reaction tank 52 and can continuously monitor the system, making it safer.

[0036] Specifically, the electrolysis assembly 3 further includes a chiller unit 34. The pump 33 is located below the water tank 31. The input end of the pump 33 is connected to the water tank 31, and the output end of the pump 33 is connected to the chiller unit 34. The chiller unit 34 is connected to the electrolyzer 32. Water in the water tank 31 enters the input end of the pump 33 by gravity and negative pressure. The pump 33 then pumps the water into the chiller unit 34. The chiller unit 34 controls the water temperature, ensuring that the water reaches a set temperature before being introduced into the electrolyzer 32. This prevents the water temperature from becoming too high, thus avoiding affecting the electrolysis efficiency and damaging the electrolyzer 32.

[0037] See Figure 2The electrolyzer 32 includes a water inlet 321, a hydrogen outlet 322, an oxygen outlet 323, a negative electrode connection 324, and a positive electrode connection 325. The water inlet 321 is connected to an external chiller unit, the hydrogen outlet 322 is connected to the gas-liquid separator 41, and the oxygen outlet 323 is connected to the water tank 31. The negative electrode connection 324 and the positive electrode connection 325 are respectively connected to the electrodes of the power supply assembly 7. The hydrogen produced in the electrolyzer 32 enters the gas-liquid separator 41 through the hydrogen outlet 322 for processing, while the produced oxygen and excess water vapor return to the water tank 31 through the oxygen outlet 323. The oxygen is discharged from the water tank 31, while the excess water vapor can return to the water tank 31 for recycling. Separate discharge of oxygen and hydrogen can minimize safety risks.

[0038] To further process hydrogen and improve hydrogen dissolution efficiency, the processing component 4 also includes a purifier 42. The purifier 42 further purifies the hydrogen. The gas-liquid separator 41 includes a hydrogen outlet 411, which is connected to the inlet of the purifier 42. The purifier 42 is connected to an external heat source for preliminary filtration. The dried hydrogen enters the purifier 42, where the external heat source heats the hydrogen. Utilizing the differences in diffusion rates and adsorption characteristics between hydrogen and other substances, impurities such as water vapor, oxygen, carbon dioxide, and chlorine are removed from the hydrogen, further purifying it. The purified hydrogen improves the purity of the dissolved hydrogen, thereby increasing the hydrogen dissolution efficiency.

[0039] To cool the purified hydrogen for subsequent hydrogen dissolution, the processing assembly 4 also includes a cooling chamber 43. One end of the cooling chamber 43 is connected to the outlet of the purifier 42, and the other end is connected to the booster 51. The cooling chamber 43 is also connected to an external cooling device. The purified hydrogen enters the cooling chamber 43, where it is cooled by the external cooling device. After cooling, the hydrogen is then introduced into the booster 51 and from there into the reaction tank 52 for hydrogen dissolution.

[0040] The processing component 4 also includes a precision filter 44, which is located between the gas-liquid separator 41 and the purifier 42, and between the purifier 42 and the cooling chamber 43. Typically, the hydrogen produced by water electrolysis may contain some impurities or particles, which may affect the purity and stability of the hydrogen, and may even damage the equipment. The precision filter 44, through its designed micropores or filter media, can effectively trap these impurities and particles inside the filter, making the hydrogen after filtration purer. This protects the purifier 42 and the cooling chamber 43, and also helps to improve the purity of the hydrogen.

[0041] The gas-liquid separator 41 is connected to an external cooling device. The gas-liquid separator 41 also includes a liquid outlet 412, which is connected to the bottom of the water tank 31. The external cooling device can condense the liquid in the hydrogen and discharge it from the liquid outlet 412 back to the water tank 31.

[0042] The reaction vessels 52 are multiple and inclined. This inclined arrangement reduces the overall height of the reaction vessels 52, facilitating operations such as adding materials to their openings. Furthermore, the inclined arrangement results in a horizontal cross-sectional area at a certain height that is larger than the diameter at that height. Therefore, compared to a vertical arrangement, a larger area is available for the hydrogen and water to react and dissolve, further improving hydrogen dissolution efficiency. Simultaneously, the ultrasonic generator 521 at the bottom reduces the accumulation of bottom bubbles, causing them to rise. Due to the inclined wall of the reaction vessel 52, these bubbles gradually approach the inclined sidewall during their ascent, forcing them to move to the wall of the reaction vessel 52. This prevents the bubbles from affecting the reaction in the middle, thereby improving hydrogen dissolution efficiency.

[0043] Specifically, see Figure 3 The angle α between the centerline of the reaction vessel 52 and the horizontal plane ranges from 40° to 50°. A solenoid valve 58 is provided between the booster 51 and each of the reaction vessels 52, and the solenoid valve 58 individually controls whether each reaction vessel 52 undergoes hydrogen dissolution.

[0044] See Figure 4 This invention also discloses a method for producing and dissolving hydrogen, applied to the hydrogen production and dissolving system described above. The method includes the following steps:

[0045] S01, real-time detection of water level and water temperature in water tank 31. When the water level in water tank 31 rises to the preset water level value and the water temperature reaches the preset water temperature value, start pump 33.

[0046] S02, start the electrolyzer 32 to electrolyze water, monitor the hydrogen flow rate in real time, and start the booster 51 to pressurize the reaction tank 52 after the hydrogen flow rate reaches the preset value.

[0047] S03, Real-time monitoring of the pressure inside the reaction vessel 52. When the pressure inside the vessel reaches the preset reaction pressure value, the ultrasonic generator 521 is activated to maintain the pressure in the reaction vessel 52 and start timing. When the time reaches the preset reaction time value, the ultrasonic generator 521 and the pressure booster 51 are turned off and the pressure in the reaction vessel 52 is released.

[0048] Before electrolysis, it is necessary to ensure smooth water circulation to prevent dry burning of the electrolyzer 32. Therefore, before starting the electrolyzer 32, the pump 33 needs to be started to circulate water between the water tank 31, the electrolyzer 32, and the gas-liquid separator 41. To improve electrolysis efficiency, the water in the water tank 31 needs to be treated, specifically by controlling the water temperature. The chiller unit 34 controls the water temperature. When the water temperature reaches the preset value and the water level in the water tank 31 rises to the preset level, the pump 33 can be started. The preset water temperature and water level values ​​can be set in advance.

[0049] After the electrolyzer 32 is started to electrolyze water, it takes a period of time for the hydrogen production rate and flow rate to gradually stabilize. During this process, hydrogen is continuously fed into the reaction tank 52. After the hydrogen flow rate reaches the preset value, the reaction tank 52 is filled with enough hydrogen. At this time, the booster 51 is started to pressurize the reaction tank 52, making the reaction tank 52 a high-pressure container.

[0050] When the pressure inside the reaction vessel 52 reaches the preset reaction pressure value, it enters a pressure-holding state and begins timing. At this time, the ultrasonic generator 521 is activated, generating high-frequency ultrasonic vibrations. Under high pressure and high-frequency vibrations, hydrogen dissolves in water more quickly. After a period of time, when the accumulated time reaches the preset reaction time value, the hydrogen dissolution operation is complete. At this point, the ultrasonic generator 521 and the pressure booster 51 are shut off, and the pressure in the reaction vessel 52 is released, discharging the excess hydrogen and ensuring system safety.

[0051] The above process does not require hydrogen storage or the construction of a conveying system between the storage and reaction containers. It can directly perform a hydrogen dissolution reaction on the hydrogen produced by electrolysis, thus saving storage and transportation equipment and reducing safety hazards during the storage and retransport of hydrogen.

[0052] Further, see Figure 5It also includes the following steps:

[0053] S11, the chiller unit 34 is used to control the temperature of the water in the water tank 31, so that the water temperature reaches the preset value and is maintained within the preset range.

[0054] S21, after the electrolyzer 32 is started to electrolyze water to produce hydrogen, the hydrogen first passes through the gas-liquid separator 41 for gas-liquid separation. The liquid level in the gas-liquid separator 41 is detected in real time. After the liquid level reaches the preset value, the liquid in the gas-liquid separator 41 is introduced into the water tank 31.

[0055] S31, the hydrogen gas from the gas-liquid separator 41 first enters the purifier 42 for purification. During the purification process, the purifier 42 is heated by an external heat source. After being heated to the set purification temperature, it is kept at that temperature. The purified hydrogen gas then enters the cooling chamber 43. An external cooling device cools the hydrogen gas through the cooling chamber 43. After being cooled to the preset cooling temperature, the hydrogen gas is introduced into the booster 51.

[0056] S11 is the process of treating the water in the water tank 31. The preset water temperature value is within the preset water temperature range. In this embodiment of the invention, the preset water temperature value can be selected within the range of 20℃-28℃. The preset water temperature range differs from the preset water temperature value by 2℃. The chiller unit 34 controls the water temperature within the range of 18℃-30℃ to improve the efficiency of electrolysis.

[0057] The gas-liquid separator 41 is connected to an external cooling device, which can cool the separation part of the gas-liquid separator 41, so that all the liquid in the mixed gas is condensed out, and the condensed liquid returns to the water tank 31, thereby forming a cycle.

[0058] To further filter and purify the hydrogen, the hydrogen from the gas-liquid separator 41 first enters the purifier 42 for purification. The purifier 42 is filled with a specific adsorbent that selectively adsorbs impurities in the hydrogen. When the impurity-containing hydrogen enters the purifier 42, under a certain pressure, the adsorbent adsorbs impurity molecules such as water, oxygen, and other gaseous components, while the hydrogen molecules, due to their small molecular size and weak interaction with the adsorbent, can pass through the adsorption layer, thus achieving hydrogen purification. Heating the purifier 42 can improve the efficiency of impurity adsorption, thereby improving the purification efficiency. During this process, the hydrogen is heated. To control the temperature of the hydrogen within an optimal range before dissolution, the cooling chamber 43 can cool the hydrogen. After cooling to a preset temperature, the hydrogen is introduced into the reaction vessel 52 to prepare for the reaction.

[0059] Furthermore, it also includes the following steps:

[0060] The booster 51 is connected to multiple reaction vessels 52, which take turns pressurizing, holding, and depressurizing. Specifically, after one reaction vessel 52 completes pressurization, holding, and depressurization in sequence, the next reaction vessel 52 starts pressurization, holding, and depressurization in sequence. Before the current reaction vessel 52 completes pressurization, holding, and depressurization, the solenoid valves 53 corresponding to the other reaction vessels 52 are closed. After the current reaction vessel 52 completes pressurization, holding, and depressurization, the solenoid valve 53 corresponding to that reaction vessel 52 is closed, and the solenoid valve 53 corresponding to the next reaction vessel 52 is opened.

[0061] Pressurizing multiple reaction vessels 52 one by one ensures the safety of the operation. Since the materials, structures, and sealing performance of each reaction vessel 52 may differ, and pressurization may cause a rapid increase in internal pressure, if all reaction vessels 52 are pressurized simultaneously, any abnormality, such as a leak or rupture in one vessel, could trigger a chain reaction, increasing the risk of accidents. Pressurizing one by one allows for the timely detection and handling of potential safety hazards, ensuring the safe and stable operation of each reaction vessel 52. Secondly, pressurizing one by one facilitates precise control of the hydrogen dissolution process within each reaction vessel 52. The volume, shape, and internal hydrogen-water mixing conditions of different reaction vessels 52 may vary, affecting hydrogen dissolution efficiency. By pressurizing one by one, the pressurization rate and pressure level can be adjusted according to the actual conditions of each reaction vessel 52, and preset reaction pressure and reaction time values ​​can be set individually for each vessel 52, ensuring that hydrogen is fully dissolved in each vessel, thereby improving hydrogen dissolution efficiency and hydrogen utilization. In this embodiment of the invention, the preset reaction pressure is between 1.5 MPa and 2.5 MPa, and the preset reaction pressure of each reaction vessel 52 can be set according to different dissolution requirements.

[0062] Before the current reaction vessel 52 completes pressurization, pressure holding, and pressure release, the solenoid valves 53 corresponding to the other reaction vessels 52 are closed to prevent hydrogen from entering the other reaction vessels 52. After the current reaction vessel 52 completes pressurization, pressure holding, and pressure release, the solenoid valve 53 corresponding to that reaction vessel 52 is closed, and the solenoid valve 53 corresponding to the next reaction vessel 52 is opened to prevent the pressure release operation of the previous reaction vessel 52 from affecting the next reaction vessel 52. Therefore, the pressure release operation of the previous reaction vessel 52 and the pressurization operation of the next reaction vessel 52 can be carried out simultaneously, improving the overall operating efficiency.

[0063] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.

The liquid level in the gas-liquid separator is monitored in real time. Once the liquid level reaches the preset value, the liquid in the gas-liquid separator is introduced into the water tank. The hydrogen gas exiting the gas-liquid separator first enters the purifier for purification. During the purification process, an external heat source is used to heat the purifier. After heating to the set purification temperature, the temperature is maintained. The purified hydrogen gas then enters the cooling chamber, where an external cooling device cools the hydrogen gas. Once the hydrogen gas temperature drops to the preset cooling temperature, it is introduced into the reaction vessel.

9. The method for producing and dissolving hydrogen according to claim 7, characterized in that, It also includes the following steps: The booster is connected to multiple reaction vessels, which alternately perform pressurization, pressure holding, and pressure release. After the previous reaction vessel has completed pressurization, pressure holding and pressure release in sequence, the next reaction vessel will start pressurization, pressure holding and pressure release in sequence. Before the current reaction vessel completes pressurization, pressure holding, and pressure release, the solenoid valves corresponding to the other reaction vessels are closed; after the current reaction vessel completes pressurization, pressure holding, and pressure release, the solenoid valve corresponding to that reaction vessel is closed, and the solenoid valve corresponding to the next reaction vessel is opened.
