[0002] Hydrogen is a secondary energy source. As an industrial raw material, it boasts a wide range of sources, diverse applications, and is clean and efficient. Hydrogen production through water electrolysis is a technology well-suited to the conversion, storage, and utilization of renewable energy. It features readily available raw materials, excellent efficiency, a simple system, high product purity, environmental friendliness, and a high cost-effectiveness.

[0003] However, there is a large amount of electrolyte and heat-absorbing metal components inside the electrolyzer of the alkaline water electrolysis hydrogen production system. During the cold start process, a large amount of heat is transferred to the metal components through the electrolyte, resulting in slow heating and high energy consumption of the alkaline water electrolysis hydrogen production system, which in turn leads to slow cold start speed. A large amount of waste hydrogen and waste oxygen is discharged during the cold start process, affecting the stability of the water electrolysis hydrogen production system. Summary of the Invention

The electrolyte flows into the flow distribution valve from the water inlet and flows out from the first water outlet or the second water outlet. The first water outlet is connected to the second node of the main water pipe via a first water pipe.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Hydrogen is a secondary energy source with diverse sources, multiple uses, and a clean, efficient, and efficient design. It is a crucial energy medium and production raw material for achieving zero-carbon goals in the future. Hydrogen production through water electrolysis involves using direct current (DC) as an energy source to decompose water into hydrogen and oxygen. Hydrogen production relies on readily available raw materials, produces high-purity products, and boasts a simple system architecture. It is environmentally friendly and cost-effective, making it the most suitable hydrogen production technology for the conversion, storage, and utilization of renewable energy.

[0038] At present, the energy consumption, lifespan and cost of alkaline water electrolysis hydrogen production systems basically meet current needs. However, due to the presence of a large amount of electrolyte and heat-absorbing metal components inside the alkaline electrolyzer, a large amount of heat is transferred to the metal components through the electrolyte during the cold start process, resulting in slow heating and high energy consumption of the alkaline water electrolysis hydrogen production system, which in turn leads to a slow cold start speed. A large amount of waste hydrogen and waste oxygen is discharged during the cold start process, affecting the stability of the water electrolysis hydrogen production system.

[0039] Therefore, an embodiment of the present invention provides a cold start control system, which achieves the effect of increasing the cold start speed by setting a flow distribution valve.

[0040] In this embodiment, a cold start control system is provided. Figure 1 is a structural diagram of a cold start control system according to an embodiment of the present invention. Figure 1 As shown, the system includes an alkaline electrolyzer, a heater, a first temperature sensor, and a control unit, wherein the alkaline electrolyzer is used to electrolyze the electrolyte in the main water pipe to produce hydrogen. A flow distribution valve is arranged at the first node of the main water pipe, including a water inlet, a first water outlet, and a second water outlet. The electrolyte flows into the flow distribution valve from the water inlet and flows out from the first water outlet or the second water outlet. The first water outlet is connected to the second node of the main water pipe through the first water pipe. The second water outlet is connected to the second node of the main water pipe through the alkaline electrolyzer. The heater is used to heat the electrolyte. The first temperature sensor is used to measure the temperature of the electrolyte flowing through the first water pipe. The control unit is used to control the flow ratio of the first water outlet and the second water outlet in the flow distribution valve according to the temperature measurement result of the first temperature sensor.

[0041] Cold start control is to control the cold start process of the electrolysis water hydrogen production system. When the electrolysis water hydrogen production system is started cold, the control unit of the cold start control system starts the electrolyte circulation and turns on the heater to heat the electrolyte. The flow distribution valve diverts the electrolyte flowing into the water inlet to the first water outlet and the second water outlet according to the initially set flow ratio, or the control unit adjusts the flow ratio of the flow distribution valve before the cold machine is started. When the cold machine is started, the flow distribution valve diverts the electrolyte according to the flow ratio adjusted by the control unit. After the electrolyte is diverted, a part of the electrolyte directly flows into the second node of the main water pipe through the first water pipe, that is, the outlet of the alkaline electrolytic cell, without flowing through the alkaline electrolytic cell. This avoids the heat loss caused by heat exchange between this part of the electrolyte and the alkaline electrolytic cell body, speeds up the electrolyte heating rate, shortens the time from cold start to normal operation of the electrolysis water hydrogen production system, and improves the efficiency of the cold start. When the temperature measurement result of the first temperature sensor received by the control unit reaches the first temperature threshold, that is, when the temperature of the electrolyte flowing through the first water pipe reaches the preset threshold, the control unit controls the flow ratio of the flow distribution valve so that the electrolyte flows into the alkaline electrolyzer. The cold start ends, the control unit turns on the alkaline electrolyzer, and the electrolysis water hydrogen production system begins the final heating process before entering the normal hydrogen production state (that is, the heating process of all electrolytes passing through the alkaline electrolyzer).

[0042] Optionally, the flow distribution valve allocates a large flow ratio to the first water outlet and the second water outlet at the beginning of the cold start, for example, greater than 0.6, so that most of the electrolyte does not pass through the alkaline electrolyzer; the flow ratio at the end of the cold start is small, for example, 0, so that the electrolyte basically flows into the alkaline electrolyzer to participate in hydrogen production.

[0043] In a possible embodiment, the system further includes a second temperature sensor for measuring the temperature of the electrolyte flowing through the alkaline electrolysis cell.

[0044] When the temperature measurement result of the second temperature sensor received by the control unit reaches the second temperature threshold, that is, when the temperature of the electrolyte flowing through the alkaline electrolyzer reaches the second temperature threshold, the final heating process ends, indicating that the electrolysis of water to produce hydrogen has reached the required temperature and will not produce a large amount of waste oxygen and waste hydrogen due to the low temperature. At this time, the control unit can determine that the alkaline electrolyzer is in normal working condition, that is, the electrolysis of water to produce hydrogen system has entered a normal hydrogen production state.

[0045] In a possible implementation manner, the heater is provided on the main water pipe; or, the heater is provided on the first water pipe.

[0046] The position of the heater can be set according to needs. For example, it can be set on the main water pipe to directly heat the electrolyte flowing through the setting location, or it can be set on the first water pipe to heat the electrolyte flowing through the branch where the first water pipe is located. Both settings can heat the electrolyte.

[0047] Optionally, the system further includes a third temperature sensor for measuring the temperature of the electrolyte flowing through the main water pipe. The control system can also directly determine whether the alkaline electrolytic cell is in normal working condition based on the temperature of the main water pipe measured by the third temperature sensor.

[0048] It should be noted that Figure 1 In the figure, the manifold is the first water pipe, x represents the flow rate proportion of the first water outlet, 1-x represents the flow rate proportion of the second water outlet, T1 is the first temperature sensor, T2 is the second temperature sensor, and T3 is the third temperature sensor.

[0049] The cold start control system provided in this embodiment is configured with a flow distribution valve so that at the beginning of a cold start, the flow distribution valve can divert the electrolyte flowing through, so that a portion of the electrolyte does not flow through the alkaline electrolytic cell. This avoids heat loss due to heat exchange between this portion of the electrolyte and the alkaline electrolytic cell body, accelerates the temperature rise of the electrolyte, shortens the time from cold start to normal operation of the water electrolysis hydrogen production system, and improves the efficiency of the cold start.

[0050] According to an embodiment of the present invention, an embodiment of a cold start control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0051] In this embodiment, a cold start control method is provided, which is applied to Figure 1 The control unit of the cold start control system shown in the embodiment, Figure 2 FIG. 1 is a flow chart of a cold start control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0052] Step S201 , setting a first flow ratio between the first water outlet and the second water outlet, starting electrolyte circulation, and starting a heater to heat the electrolyte.

[0053] When the electrolysis hydrogen production system is started, the control unit sets a first flow rate ratio between the first and second water outlets, starts electrolyte circulation, and turns on the heater to heat the electrolyte. Optionally, the first flow rate is relatively large, for example, greater than 0.6, so that most of the electrolyte does not flow through the alkaline electrolytic cell and lose heat.

[0054] Step S202 : comparing a first temperature result of a first temperature sensor with a first temperature condition; if the first temperature result satisfies the first temperature condition, adjusting the first water outlet and the second water outlet to a second flow ratio, and starting the alkaline electrolytic cell.

[0055] The first temperature condition may be a temperature condition for the final heating process (that is, the heating process of all electrolytes passing through the alkaline electrolyzer) before the electrolysis water hydrogen production system begins to enter the normal hydrogen production state, and may be set according to actual needs, for example, to 60 to 80°C. When the first temperature result satisfies the first temperature condition, that is, when the temperature of the electrolyte flowing through the first water pipe satisfies the first temperature condition, the control unit adjusts the first water outlet and the second water outlet to a second flow ratio, which is less than the first flow ratio, so that the electrolyte can flow into the alkaline electrolyzer to participate in the subsequent hydrogen production process. The second flow rate is relatively small, for example, 0, so that the electrolyte basically flows into the alkaline electrolyzer to participate in hydrogen production.

[0056] The cold start control method provided in this embodiment sets a first flow ratio between the first water outlet and the second water outlet at the beginning of the cold start, which can divert the electrolyte flowing through the flow distribution valve so that a portion of the electrolyte does not flow through the alkaline electrolytic cell, thereby avoiding heat loss due to heat exchange between this portion of the electrolyte and the alkaline electrolytic cell body, accelerating the electrolyte heating rate, and shortening the time from cold start to normal operation of the electrolysis water hydrogen production system. In addition, when the first temperature result meets the first temperature condition, the first water outlet and the second water outlet are adjusted to the second flow ratio, so that the electrolyte can flow into the alkaline electrolytic cell to participate in the subsequent hydrogen production process, thereby improving the efficiency of the cold start.

[0057] In this embodiment, a cold start control method is provided, which is applied to Figure 1 The control unit of the cold start control system shown in the embodiment, Figure 3 FIG. 1 is a flow chart of a cold start control method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0058] Step S301, setting a first flow ratio between the first water outlet and the second water outlet, starting electrolyte circulation, and starting a heater to heat the electrolyte.

[0059] Optionally, the cold start control system also includes a second temperature sensor for measuring the temperature of the electrolyte flowing through the alkaline electrolyzer. When the temperature measurement result of the second temperature sensor reaches a second temperature threshold, that is, when the temperature of the electrolyte flowing through the alkaline electrolyzer reaches the second temperature threshold, the final heating process ends, indicating that the electrolysis of water to produce hydrogen reaction reaches the required temperature and does not produce a large amount of waste oxygen and waste hydrogen due to the low temperature. At this time, the control unit can turn on the alkaline electrolyzer, and the electrolysis of water to produce hydrogen system enters a normal hydrogen production state.

[0060] Optionally, the first flow ratio is that the cold start control test system sets the temporary flow ratio in sequence from 0 to 1 according to a preset numerical interval, and records the time consumed by starting the heater to heat the electrolyte to the second temperature under each temporary flow ratio to meet the second temperature condition, and determines it according to the temporary flow ratio with the smallest consumption time. The second temperature condition is the temperature at which the electrolysis water hydrogen production system can produce hydrogen normally, which can be set according to actual needs, for example, to about 60°C. The cold start control test system has the same structure as the cold start control system, and the temporary flow ratio is the flow ratio of the first water outlet to the second water outlet in the cold start control test system. In other words, an actual experiment can be carried out in advance with a cold start control test system with the same structure as the cold start control system to determine the first flow ratio that can make the electrolysis water hydrogen production system consume the shortest time from cold start to entering the normal hydrogen production state. It should be noted that the first flow ratios corresponding to different first temperature conditions and second temperature conditions are not necessarily the same. For example, taking the second temperature condition as 60°C and the first temperature condition increasing from 60°C to 80°C, the consumption time (unit: seconds) under each temporary flow ratio is as follows:

[0061] Table 1: Consumption time under different temporary traffic ratios.

[0062]

[0063] Step S302 : comparing a first temperature result of a first temperature sensor with a first temperature condition; if the first temperature result satisfies the first temperature condition, adjusting the first water outlet and the second water outlet to a second flow ratio, and starting the alkaline electrolytic cell.

[0064] The second flow ratio is smaller than the first flow ratio.

[0065] For details, please see Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0066] Step S303 : comparing the second temperature result of the second temperature sensor with the second temperature condition. If the second temperature result satisfies the second temperature condition, it is determined that the alkaline electrolytic cell is in a normal working state.

[0067] When the temperature measurement result of the second temperature sensor received by the control unit reaches the second temperature threshold, that is, when the temperature of the electrolyte flowing through the alkaline electrolyzer reaches the second temperature threshold, the final heating process ends, indicating that the electrolysis of water to produce hydrogen has reached the required temperature and will not produce a large amount of waste oxygen and waste hydrogen due to the low temperature. At this time, the control unit can determine that the alkaline electrolyzer is in normal working condition, that is, the electrolysis of water to produce hydrogen system enters the normal hydrogen production state, and then collects qualified hydrogen produced by normal hydrogen production.

[0068] Optionally, the cold start control system further includes a third temperature sensor for measuring the temperature of the electrolyte flowing through the main water pipe. The control system can also directly determine whether the alkaline electrolytic cell is in normal working condition based on the temperature of the main water pipe measured by the third temperature sensor.

[0069] For example, Figure 4 A temperature change curve diagram related to an embodiment of the present application is shown. The electrolyzer outlet temperature is the temperature measured by the second temperature sensor, and the electrolyzer temperature is the temperature of the electrolyzer body, which can be measured by corresponding temperature sensors. This shows that the temperature rise of the electrolyte after diversion through this solution is less affected by the electrolyzer body, resulting in faster temperature rise, thereby improving cold start efficiency and allowing the water electrolysis hydrogen production system to enter normal hydrogen production more quickly.

[0070] The cold start control method provided in this embodiment sets a first flow ratio between the first water outlet and the second water outlet at the beginning of the cold start, which can divert the electrolyte flowing through the flow distribution valve so that a portion of the electrolyte does not flow through the alkaline electrolytic cell, thereby avoiding heat loss due to heat exchange between this portion of the electrolyte and the alkaline electrolytic cell body, accelerating the electrolyte heating rate, and shortening the time from cold start to normal operation of the electrolysis water hydrogen production system. In addition, when the first temperature result meets the first temperature condition, the first water outlet and the second water outlet are adjusted to the second flow ratio, so that the electrolyte can flow into the alkaline electrolytic cell to participate in the subsequent hydrogen production process, thereby improving the efficiency of the cold start.

[0071] This embodiment also provides a cold start control device for implementing the above-mentioned embodiments and preferred implementations. Details already described will not be repeated. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0072] This embodiment provides a cold start control device for use in Figure 1 The control unit of the cold start control system shown in the embodiment is as follows: Figure 5 As shown, including:

[0073] A starting module 501 is used to set a first flow ratio between the first water outlet and the second water outlet, start the electrolyte circulation, and start the heater to heat the electrolyte;

[0074] The comparison module 502 is used to compare the first temperature result of the first temperature sensor with the first temperature condition. If the first temperature result meets the first temperature condition, the first water outlet and the second water outlet are adjusted to a second flow ratio and the alkaline electrolytic cell is started; the second flow ratio is less than the first flow ratio.

[0075] In an optional embodiment, the system further includes a second temperature sensor for measuring the temperature of the electrolyte flowing through the alkaline electrolytic cell. The system further includes a working status determination module for comparing a second temperature result of the second temperature sensor with a second temperature condition. If the second temperature result meets the second temperature condition, it is determined that the alkaline electrolytic cell is in a normal working state.

[0076] In an optional embodiment, the first flow ratio is that the cold start control test system sets the temporary flow ratio in sequence from 0 to 1 according to a preset numerical interval, and records the time consumed by starting the heater to heat the electrolyte to the second temperature under each temporary flow ratio so that the second temperature condition is met, and is determined based on the temporary flow ratio with the smallest consumption time; the cold start control test system has the same structure as the cold start control system; the temporary flow ratio is the flow ratio of the first water outlet to the second water outlet in the cold start control test system.
