[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1As shown, a ship combustion-supporting emission-reducing system includes a controller 10, a water tank area 20, an electrolysis area 30, a drying area 40, a water supplement unit, a water level sensor, a temperature sensor, a gas pressure sensor, and a housing 50; the controller 10 is connected with a power supply for controlling the power supply to be powered off or powered on; the water tank area 20 is connected with the controller 10 for providing alkaline water to be electrolyzed; the electrolysis area 30 is connected with the controller 10 for electrolyzing the alkaline water to generate hydrogen-oxygen mixed gas and introducing the hydrogen-oxygen mixed gas into the water tank area 20; the drying area 40 is connected with the water tank area 20 for drying the hydrogen-oxygen mixed gas and introducing the dried hydrogen-oxygen mixed gas into a combustion chamber of a ship engine; the water supplement unit is connected with the controller 10 for supplementing electrolyte to the water tank area 20; the water level sensor is arranged in the water tank area 20 and connected with the controller 10, and the water level sensor is used to send the liquid level information of the water tank area 20 to the controller 10; the controller 10 is further used to issue an alarm or control the water supplement unit to start supplementing liquid to the water tank area 20 or control the water supplement unit to stop supplementing liquid to the water tank area 20 according to the received liquid level information; the temperature sensor is arranged in the electrolysis area 30 and electrically connected with the controller 10, and the temperature sensor is used to detect the temperature of the electrolysis area 30 and send the detected temperature information to the controller 10, and the controller 10 is further used to control the power supply to be powered off when the temperature of the electrolysis area 30 is abnormal according to the temperature information; the gas pressure sensor is arranged in a gas conveying pipeline between the gas outlet of the drying area 40 and the combustion chamber of the engine, and the gas pressure sensor is used to send the gas pressure information in the gas conveying pipeline to the controller 10, and the controller 10 is further used to issue an alarm when the pressure in the gas conveying pipeline is abnormal according to the gas pressure information; the drying area 40, the water tank area 20, and the electrolysis area 30 are arranged in the housing 50 from top to bottom in sequence; wherein the power supply is connected with a main power supply of the ship.

[0034] Specifically, the shell 50 serves as the support structure of the entire system, with the drying area 40, the water tank area 20 and the electrolysis area 30 arranged in the interior from top to bottom in sequence, ensuring the stability and safety of each component. The controller 10 serves as the central command unit, connected to the power supply, responsible for the power-on and power-off control of the entire system. When the control system is on, the controller 10 also receives information from other sensors and makes decisions accordingly to control the water replenishment unit, issue alarms or control power-on and power-off, etc., to ensure the safe and stable operation of the emission reduction system. Among them, the controller 10 is also installed inside the shell 50, and the display screen end of the controller 10 can be embedded on the shell 50, and the display screen end can display real-time fault information of the emission reduction system. The entire emission reduction system has high integration and small space occupation. In addition, the shell 50 at the position of the electrolysis area 30 is provided with a ventilation port. During the electrolysis process, a certain amount of heat will be generated, causing the temperature of the electrolysis area 30 to rise. The setting of the ventilation port can effectively promote air circulation and carry away heat, thereby reducing the temperature of the electrolysis area 30 and maintaining the stability of the electrolysis process. The shell 50 is made of lightweight 304 stainless steel material, which not only provides a solid structure, but also ensures the lightweight of the equipment, facilitating transportation and installation. The 304 stainless steel has good corrosion resistance and processing performance, which can protect the internal components from external environmental erosion.

[0035] Hydrogen-oxygen mixed gas has catalytic properties. Dry CO reacts slowly with oxygen. When the gas contains 20 ppm of hydrogen, a multiphase reaction occurs, and active atoms such as O, H and OH are generated during high-temperature combustion, which can promote the high-temperature cracking of long carbon-hydrogen chains in diesel fuel and accelerate the oxidation reaction. Hydrogen-oxygen mixed combustion is a typical branched chain reaction process. When a molecule of water is formed, two new active substances are obtained. The production process of hydrogen-oxygen gas only consumes water and electricity, and 1 liter of water can produce 705 liters of hydrogen-oxygen gas, consuming about 3kWH of electricity.

[0036] The electrolysis zone 30 electrolyzes the alkaline water into hydrogen and oxygen in a ratio of 2:1. The two gases are mixed inside the electrolysis zone 30 to form a hydrogen-oxygen mixture, i.e., Brown gas, which is output to the water tank zone 20. After passing through the water tank zone 20, the hydrogen-oxygen mixture enters the drying zone 40 for gas-liquid separation to obtain dried hydrogen-oxygen mixture. The hydrogen-oxygen mixture enters the engine combustion chamber through the engine intake manifold, mixes with fuel, and burns with the help of oxygen and the catalysis of hydrogen, which promotes more complete combustion of fuel, reduces harmful emissions, and improves fuel utilization, achieving the dual effects of emission reduction and energy saving. In addition, the hydrogen-oxygen mixture entering the engine combustion chamber can also clean the engine carbon deposit. Specifically, because the combustion speed of hydrogen is very fast, and the combustion temperature is relatively high, it can produce a strong thermal shock. When this high-temperature flame spreads in the combustion chamber, it will directly impact the carbon deposit attached to the surface of the engine components. Carbon deposit is a carbonaceous deposit formed due to incomplete combustion of fuel, etc. Under the strong thermal shock of high-temperature flame, the carbon deposit becomes loose, and its internal chemical bonds are broken under high temperature, so that the carbon deposit is not easily left on the surface of the engine components; hydrogen has reducing properties, and oxygen has oxidizing properties. Under the specific environment in the engine combustion chamber, a series of redox reactions occur during the combustion of hydrogen-oxygen mixture. For carbon deposit, hydrogen can react with carbon in the carbon deposit to reduce carbon to gaseous substances such as carbon monoxide or carbon dioxide. For example, hydrogen and carbon in the carbon deposit can react under certain conditions to generate carbon monoxide. These generated gaseous products can naturally be discharged out of the engine with the engine exhaust process, thereby achieving the purpose of removing carbon deposit from the engine components. After the combustion of hydrogen-oxygen mixture in the combustion chamber, it will rapidly expand to form a gas flow with high pressure and flow rate. These gases will produce a scouring effect on the surface of the engine components during combustion in the combustion chamber and through the exhaust passage. The scouring effect carries away the loose carbon deposit particles from the surface of the engine components such as pistons, valves, and cylinder walls, so that they are discharged from the engine with the exhaust, thereby achieving the purpose of cleaning the carbon deposit.

[0037] The hydrogen-oxygen mixture gas directly enters the intake manifold of the diesel engine group through the gas pipeline. During the intake stroke of the diesel engine, the introduced hydrogen-oxygen mixture gas can be preliminarily mixed by using the movement of the intake airflow. When the piston descends, the air (containing hydrogen-oxygen mixture gas) at the intake port rapidly rushes into the cylinder, and in this process, turbulence is generated. This turbulence can preliminarily mix the hydrogen-oxygen mixture gas with the diesel fuel (which enters the cylinder during the subsequent fuel injection process). When the diesel engine is operating normally, the high-speed intake airflow generates turbulence that can entrain and partially mix the hydrogen-oxygen mixture gas with the diesel spray. In addition, the diesel engine injects diesel fuel into the cylinder through the fuel injection nozzle, which usually causes the diesel fuel to form a spray. When the hydrogen-oxygen mixture gas is present in the cylinder, the spray-shaped diesel fuel can increase the contact area with the hydrogen-oxygen mixture gas. The diesel fuel injection nozzle generally has a high injection pressure, which can atomize the diesel fuel into fine particles that disperse in the cylinder and interpenetrate with the hydrogen-oxygen mixture gas. Since the hydrogen-oxygen mixture gas also has fluidity, during the diffusion of the diesel particles, the hydrogen-oxygen mixture gas and the diesel particles can be uniformly mixed. The uniform mixing of the hydrogen-oxygen mixture gas with the engine fuel can further accelerate the combustion process of the fuel and make the combustion more complete, thereby improving the combustion efficiency. After hydrogen combustion, only water is produced, and no carbon dioxide or other greenhouse gases are produced, so the use of hydrogen mixed with fuel can reduce greenhouse gas emissions. At the same time, hydrogen can also promote the complete combustion of fuel, reduce the generation of harmful emissions such as unburned hydrocarbons (HC) and carbon monoxide (CO), and achieve the purpose of combustion promotion and emission reduction.

[0038] The mixed gas generated by the electrolysis zone 30 enters the water tank zone 20, and then some water is attached after it comes out from the water tank zone 20. In order to ensure that the hydrogen-oxygen mixture gas can be efficiently and safely burned when input into the combustion chamber of the ship engine, it is necessary to pass through the drying zone 40 for gas-liquid separation to remove the water in the hydrogen-oxygen mixture gas input into the engine combustion chamber.

[0039] The water replenishment unit realizes automatic water replenishment function through connection with the controller 10. When the water level sensor of the water tank zone 20 detects that the water level is lower than the set value, the controller 10 will automatically start the water replenishment unit to replenish the electrolyte to the water tank zone 20, ensuring that the water tank zone 20 always has enough alkaline water for the electrolysis zone 30 to use, thereby ensuring the stable operation of the entire system. The water level sensor can monitor the water level change of the water tank zone 20 in real time, and when the water level is lower than the safety threshold, the water level sensor will immediately send a signal to the controller 10. In the electrolytic hydrogen production system, if the water level of the water tank zone 20 is too low, it may cause dry burning of the electrolysis zone 30 and damage the equipment; if the water level is too high, it may cause water overflow and other safety problems. The real-time monitoring function of the water level sensor can timely discover these potential risks and take corresponding preventive measures through the joint controller 10.

[0040] The temperature sensor arranged in the electrolysis area 30 monitors the temperature of the electrolysis area 30 and sends the temperature information to the controller 10. When the temperature exceeds the preset safety value, the controller 10 controls the power supply to be powered off. By effectively cutting off the heat source of the electrolysis process, the temperature continues to rise, ensuring the safety of the equipment and personnel.

[0041] The air pressure sensor can monitor the air pressure in the gas pipeline in real time. When the air pressure is abnormal (such as too high or too low), the controller 10 will immediately issue an alarm, allowing the operator to discover and handle potential safety hazards in a timely manner, preventing equipment damage or safety accidents caused by abnormal air pressure. In addition, by monitoring the air pressure in real time, the controller 10 can ensure that the hydrogen-oxygen mixed gas maintains an appropriate pressure before being delivered to the engine combustion chamber, optimizing the engine's combustion efficiency and improving the ship's power performance and fuel economy.

[0042] The ship combustion-supporting and emission-reducing system in the present application is highly integrated, achieving effective emission reduction and energy saving of the ship engine. The controller 10 as the central control unit can accurately control the water replenishment, power-off, and alarm functions based on the information from each sensor, ensuring the stable operation and safety of the system. The electrolysis area 30 can efficiently electrolyze alkaline water into hydrogen-oxygen mixed gas, providing catalysis and combustion support for the engine fuel combustion process, significantly improving the engine fuel combustion efficiency and reducing harmful emissions. At the same time, the drying area 40 ensures that the hydrogen-oxygen mixed gas can remove the water before entering the engine combustion chamber, ensuring efficient and safe combustion. In addition, the ship combustion-supporting and emission-reducing system in the present application also has multiple safety measures such as water level monitoring, temperature monitoring, and air pressure monitoring, which can alarm or power off in time when abnormal conditions occur, effectively avoiding equipment damage and safety accidents. Therefore, the system not only achieves the dual effects of emission reduction and energy saving, but also has high automation and safety performance, providing strong support for the environmental protection and energy-saving operation of the ship.

[0043] In one possible implementation, the water tank area 20 includes a water tank 21, a water tank inlet pipe 22, a water tank outlet pipe 23, and a water tank gas outlet pipe 24; the water tank 21 is used to temporarily store alkaline water to be electrolyzed; the water tank inlet pipe 22 is connected to the water replenishment unit, the water tank inlet pipe 22 penetrates the top cover of the water tank 21, extends to the bottom plate of the water tank 21 without contacting the bottom plate, and the water tank outlet pipe 23 is arranged at the bottom of the water tank area 20, the water tank outlet pipe 23 is used to guide the electrolysis liquid in the water tank 21; the water tank gas outlet pipe 24 is arranged on the top cover of the water tank 21, and the water tank gas outlet pipe 24 is used to guide the gas in the water tank 21.

[0044] Specifically, the water tank 21 mainly temporarily stores the alkaline water to be electrolyzed, providing a stable and continuous source of electrolyzed water for the electrolysis process. It can ensure the continuity and stability of the electrolysis process and improve the electrolysis efficiency. As shown in Figure 2 The water tank inlet pipe 22 is connected to the water replenishment unit, and the water tank inlet pipe 22 penetrates the top cover of the water tank 21, extends to the bottom plate of the water tank 21 without contacting the bottom plate. The water tank outlet pipe 23 is arranged at the bottom of the water tank 21, which can ensure that the alkaline water is smoothly discharged under the action of gravity, improve the discharge efficiency of the electrolyte, and also maintain the stability of the liquid level in the water tank 21, avoiding the problem of unstable supply of electrolyte caused by fluctuation of the liquid level. Because gas is lighter than liquid, it will naturally rise to the top of the water tank 21 and be discharged through the water tank gas outlet pipe 24. The volume of the water tank 21 in this application is 50-70 liters, which can meet the amount of electrolyzed water required during the operation of the ship. The water tank 21 is made of 316 stainless steel material which is corrosion-resistant and has stability at high temperature. 316 stainless steel has better resistance to chloride ions, and is particularly suitable for environments that may contain chloride ions or other corrosive media. In addition, its high-temperature stability ensures that the water tank 21 can still maintain its structure and performance under high-temperature conditions.

[0045] In one possible implementation, the electrolysis area 30 includes multiple groups of parallel electrolysis reactors 31 and electrolysis reactor gas outlet pipes 32; the liquid inlet at the bottom of the electrolysis reactor 31 is connected to the liquid outlet of the water tank liquid outlet pipe 23; the electrolysis reactor 31 is used for electrolyzing alkaline water; one end of the electrolysis reactor gas outlet pipe 32 penetrates the bottom plate of the water tank 21 and extends to the top cover of the water tank 21 without contacting the top cover, and the other end is connected to the gas outlet at the top of the electrolysis reactor 31; the electrolysis reactor gas outlet pipe 32 is used to guide the hydrogen-oxygen mixed gas generated by the electrolysis reactor 31 into the water tank 21.

[0046] Specifically, multiple groups of parallel electrolysis reactors 31 can work simultaneously, increasing the capacity and speed of electrolysis, thereby improving the overall electrolysis efficiency. The liquid inlet at the bottom of the electrolysis reactor 31 allows the alkaline water to enter each electrolysis reactor 31 uniformly and stably, ensuring the continuity and stability of the electrolysis process. Similarly, gas is lighter than liquid, and the generated hydrogen and oxygen gas mixture will naturally rise to the top of the electrolysis reactor 31 and be discharged from the gas outlet at the top of the electrolysis reactor 31, then enter the water tank 21 through the electrolysis reactor gas outlet pipe 32. In addition, one end of the electrolysis reactor gas outlet pipe 32 extends through the bottom plate of the water tank 21 towards the top cover of the water tank 21 without contacting the top cover. In this way, the gas accumulates in the upper part of the internal space of the water tank 21 after being discharged, forming pressure on the liquid surface in the water tank 21, which facilitates the flow of electrolyte in the water tank 21 into the electrolysis reactor 31. Since the internal chamber of the electrolysis reactor 31 is connected to the water tank 21, under the action of pressure, the liquid in the electrolysis reactor 31 will also be discharged from the gas outlet of the electrolysis reactor 31 into the water tank 21, mixed with the electrolyte in the water tank, and then re-enter the electrolysis reactor 31, forming a cycle. The circulation of electrolyte between the electrolysis reactor 31 and the water tank 21 not only helps to maintain the electrolyte level in the reactor, but also accelerates heat transfer and dissipation through continuous flow, achieving cooling of the electrolysis reactor 31. During the circulation process, the electrolyte continuously removes heat from the electrolysis reactor 31 and transfers it to the crude oil electrolyte in the water tank 21, thereby achieving effective heat transfer and heat dissipation, ensuring the smooth progress of the electrolysis reaction.

[0047] The gas outlet of the electrolysis reactor 31 is also connected to a drain pipe that communicates with the outside. When it is necessary to clean the internal cavity of the electrolysis reactor 31, the drain pipe is opened, and water flows in from the top of the reactor and is discharged through the drain pipe at the bottom, thereby achieving effective internal cleaning. The electrolysis reactor 31 is made of 316 stainless steel and EPDM insulation material. The corrosion resistance and high temperature stability of 316 stainless steel ensure the stable operation of the electrolysis reactor 31 in harsh environments. The EPDM insulation material provides good electrical insulation and chemical stability, ensuring the electrical safety and chemical stability of the electrolysis reactor 31.

[0048] In this application, the electrolysis reactor 31 has at least 4 groups, and in other embodiments, it can have more groups.

[0049] In one possible implementation, the drying zone 40 includes a plurality of filter bottles 41, a return water pipe 42, and a filter bottle outlet pipe 43; each of the plurality of filter bottles 41 is equipped with a gas-liquid separator, and the filter bottles 41 are used to separate the liquid-containing gas entering the filter bottles 41; the return water pipe 42 is connected to the water tank inlet pipe 22, and the return water pipe 42 is used to guide the liquid filtered from the filter bottles 41 into the water tank 21; the filter bottle outlet pipe 43 is connected to the engine combustion chamber, and the filter bottle outlet pipe 43 is used to introduce the filtered hydrogen-oxygen mixture into the engine combustion chamber.

[0050] Specifically, the air inlet of filter bottle 41 is connected to the air outlet pipe 24 of the water tank. The hydrogen-oxygen mixture discharged from the air outlet pipe 24 sequentially enters multiple filter bottles 41. Each filter bottle 41 is equipped with a gas-liquid separator, which efficiently separates the liquid-containing gas entering the filter bottle 41, ensuring the purity of the hydrogen-oxygen mixture. The liquid filtered from the filter bottles 41 is returned to the water tank 21 via the return water pipe 42, achieving resource recycling. The number of filter bottles 41 can be increased or decreased according to the gas processing capacity to meet different needs.

[0051] In one possible implementation, the water tank area 20 further includes a gas-liquid separation net 25; the gas-liquid separation net 25 is disposed inside the water tank 21 and located between the liquid surface of the water tank 21 and the air inlet of the water tank outlet pipe 24, and is used to separate the hydrogen-oxygen mixture coming out of the water tank 21.

[0052] Specifically, the liquid level in water tank 21 refers to the highest liquid level that water tank 21 can reach after being filled with water, such as... Figure 2 As shown, the gas-liquid separation mesh 25 is located between the air inlet of the water tank outlet pipe 24 and the liquid surface of the water tank 21, and the gas-liquid separation mesh 25 is higher than the air outlet of the electrolysis reactor outlet pipe 32. The hydrogen-oxygen mixture introduced into the water tank 21 from the electrolysis reactor 31 rises through the water in the water tank 21 to the space between the liquid surface of the water tank 21 and the gas-liquid separation mesh 25. Since the hydrogen-oxygen mixture still contains some liquid, the gas-liquid separation mesh 25 can separate the liquid. The separated liquid enters the water tank 21, while the separated hydrogen-oxygen mixture enters the water tank outlet pipe 24 from the air inlet and further enters the drying zone 40 from the air outlet of the water tank outlet pipe 24 for further drying.

[0053] In one possible implementation, the water replenishment unit includes a water replenishment tank 21 and a delivery pump; the water replenishment tank 21 is pre-stored with alkaline water to be electrolyzed; the delivery pump is connected to a controller 10; the controller 10 is used to control the water replenishment tank 21 to replenish the water tank 21 or to control the water replenishment tank 21 to stop replenishing the water tank 21 by controlling the opening and closing of the delivery pump.

[0054] Specifically, in the present application, the delivery pump is placed on the top cover of the water tank 21 in the shell 50, and the delivery pump is connected with the controller 10. The controller 10 adjusts the liquid supplementing amount of the water tank 21 to the water tank 21 by controlling the opening and closing of the delivery pump, and the automatic control improves the operation efficiency of the system.

[0055] In a possible implementation, a standby water inlet is further arranged on the water tank 21, which is used to manually open the standby water inlet to supplement water to the water tank 21 when the water supplementing unit fails.

[0056] Specifically, when the water supplementing unit fails, the standby water inlet can be quickly manually opened, and water is manually added to the water tank 21 through a kettle or a bucket or the like, so that the water level in the water tank 21 does not decrease due to water shortage, thereby maintaining the normal operation of the system, reducing the risk of system shutdown caused by failure of the water supplementing system, and improving the reliability and stability of the entire system. The standby water inlet is provided with a small window on the shell 50 on one side, and the small window is manually opened before the standby water inlet is opened when manual water addition is needed.

[0057] In a possible implementation, the marine combustion-supporting and emission-reducing system further comprises a rotation speed collector connected with the controller 10, the rotation speed collector is used to collect engine rotation speed information and send the engine rotation speed information to the controller 10, and the controller 10 adjusts the electrolysis current of the electrolysis area 30 according to the engine rotation speed information.

[0058] Specifically, the engine rotation speed information is collected in real time through the rotation speed collector, and the controller 10 can accurately master the working state of the engine. The electrolysis current of the electrolysis area 30 is adjusted according to the engine rotation speed, so that the electrolysis process can be matched with the output power of the engine, and energy waste caused by too large electrolysis current or low electrolysis efficiency caused by too small electrolysis current can be avoided.

[0059] The present application further provides a marine combustion-supporting and emission-reducing control method applied to the marine combustion-supporting and emission-reducing system in the present application, and the control method comprises the following steps:

[0060] When the electric power of the ship is sufficient, the main power supply of the ship is used to supply power to the power supply;

[0061] When the water level of the water tank area 20 reaches the first preset water level threshold, the water level sensor sends the first water level information to the controller 10, and after the controller 10 receives the first water level information, the controller 10 sends the first alarm information and controls the water supplement unit to supplement water to the water tank area 20; if the controller 10 does not receive the second water level information after the first time length after sending the first alarm information, the controller 10 sends the second alarm information; if the controller 10 still does not receive the second water level information after the second time length after sending the second alarm information, the controller 10 controls the power supply to be powered off; the second water level information is the water level information sent by the water level sensor to the controller 10 when the water level of the water tank area 20 reaches the second preset water level threshold;

[0062] When the water level of the water tank area 20 reaches the second preset water level threshold, the water level sensor sends the second water level information to the controller 10, and after the controller 10 receives the second water level information, the controller 10 controls the water supplement unit to stop supplementing water to the water tank area 20;

[0063] The controller 10 receives the temperature information sent by the temperature sensor and compares the temperature value in the temperature information with the preset temperature threshold, and the controller 10 controls the power supply to be powered off when judging that the temperature value is higher than the preset temperature threshold.

[0064] The controller 10 receives the pressure information sent by the pressure sensor and compares the pressure value in the pressure information with the preset pressure threshold, and the controller 10 controls the power supply to be powered off when judging that the pressure value is higher than the preset pressure threshold.

[0065] Specifically, under the normal operation condition of the ship, the generator set is designed according to the power demand of the whole ship and continuously runs. Various types of electrical equipment form a relatively stable but not constant power consumption curve according to their respective work tasks and operation modes. From the design redundancy and reliability principle of the power system, the rated power of the ship generator set must be able to cover all possible power demand peaks in extreme conditions and leave a certain safety margin. In actual daily operation, the ship will not be in this extreme power demand state most of the time, which leads to the existence of continuous residual current after the generated electric energy of the generator set meets the actual power consumption of the electrical equipment, that is, the excess current. The power supply of the power supply of the present application is supplied by the excess current of the main power supply, thereby improving the comprehensive utilization efficiency of the ship energy. Since the power supply is connected with the main power supply of the ship, when the ship engine starts to work (that is, the engine is powered on), the ship combustion-supporting emission-reducing system will start simultaneously.

[0066] The water level sensor is provided with a highest liquid level threshold and a lowest liquid level threshold, the first preset water level threshold is the lowest water level threshold, and the second preset water level threshold is the highest liquid level threshold.

[0067] In the electrolysis process in the electrolysis area 30, when the electrolyte level drops to the minimum liquid level threshold, the water level sensor sends a water level information signal to the controller 10, and the controller 10 immediately issues a first alarm, i.e. the first alarm information, and the controller 10 starts the water replenishment unit to add electrolyte to the water tank area 20. If the controller 10 does not receive the second water level information after a first time period after issuing the first alarm information, it means that the water replenishment unit fails to normally add electrolyte, and the controller 10 issues a second alarm to remind the operator again. If the controller 10 still does not receive the second water level information after a second time period after issuing the second alarm information, it means that the water replenishment unit still fails to normally add electrolyte, at this time it means that the water replenishment unit has a fault, in order to prevent the electrolysis area 30 from burning dry, the controller 10 controls the power supply to be powered off, so as to ensure the safety and stability of the system operation. The first time period is the time period for the water tank area 20 liquid level to rise from the minimum liquid level threshold to the maximum liquid level threshold when the water replenishment unit is working normally. The second time period is the time period for the water tank area 20 liquid level to increase from zero to the minimum liquid level threshold.

[0068] If the controller 10 starts the water replenishment unit and receives the second water level information sent by the water level sensor after the first time period, it means that the electrolyte in the water tank 21 has reached the maximum liquid level threshold, and the controller 10 controls the water replenishment unit to stop replenishing liquid to the water tank area 20.

[0069] The temperature sensor transmits the monitored temperature information to the controller 10, and the controller 10 compares the temperature value in the received temperature information with the preset temperature threshold. When the controller 10 judges that the actual temperature value of the electrolysis area 30 is higher than the preset temperature threshold, it means that the current electrolysis area 30 has an overheating risk, and if timely measures are not taken, it may cause equipment damage. Therefore, the controller 10 will immediately start the emergency protection mechanism, quickly cut off the power supply of the equipment by sending a power-off instruction to the power supply, so as to effectively curb the further rise of temperature and protect the safety of equipment and personnel.

[0070] The gas pressure sensor is installed in the gas outlet pipeline of the electrolysis area 30. When the hydrogen-oxygen mixed gas generated by the electrolysis area 30 flows through the gas pressure sensor, the I / O port of the gas pressure sensor will convert the gas pressure signal into a digital signal and send it to the controller 10, and after calculation, the instantaneous pressure value is displayed. Once the detected pressure value exceeds the preset pressure threshold in the controller 10, the controller 10 controls the power supply to be powered off, so that the system stops running, thereby ensuring the safety and stability of the system and avoiding potential dangerous conditions or equipment failures caused by excessive pressure.

[0071] In one possible implementation, the control method further comprises:

[0072] The controller 10 receives the engine speed information sent by the rotation speed collector,

[0073] When the controller 10 judges that the engine speed is greater than or equal to the first speed threshold and less than the second speed threshold, the controller 10 adjusts the electrolysis current value of the electrolysis area 30 to the first preset current value;

[0074] When the controller 10 judges that the engine speed is greater than or equal to the second speed threshold and less than the third speed threshold, the controller 10 adjusts the electrolysis current value of the electrolysis area 30 to the second preset current value;

[0075] When the controller 10 judges that the engine speed is greater than or equal to the third speed threshold, the controller 10 adjusts the electrolysis current value of the electrolysis area 30 to the third preset current value;

[0076] Wherein, the first preset current value is less than the second preset current value, and the second preset current value is less than the third preset current value.

[0077] Specifically, the amount of hydrogen-oxygen mixed gas required to achieve the best working condition improvement effect is different at different engine speeds. The controller 10 adjusts the current size according to the engine speed. The engine speed increases, and the controller 10 increases the electrolysis current of the electrolysis area 30. The engine speed decreases, and the controller 10 reduces the electrolysis current of the electrolysis area 30. The working condition of the engine mainly includes three categories: low speed working condition, medium speed working condition and high speed working condition.

[0078] Wherein, the low speed working condition, the speed of the engine is greater than or equal to the first speed threshold and less than the second speed threshold. The low speed working condition mainly includes:

[0079] I. Low speed of the ship: When the ship slowly drives near the port, enters and exits the port, or low speed in the narrow waterway, the main engine speed is at a low level, for example, the main engine speed of large ships is about 50-100 revolutions / minute. The power demand of the ship is small under this working condition, and the intake and fuel injection amount are relatively small. At this time, a small amount of hydrogen-oxygen mixed gas is introduced into the intake system, which has a significant effect on improving the fuel combustion condition. The commonly used fuel of the ship, such as heavy oil, has high viscosity and is difficult to atomize and burn. The hydrogen in the hydrogen-oxygen mixed gas has high activity, which can reduce the ignition energy of the fuel, so that the heavy oil can be ignited at a lower temperature, thereby making the combustion process more stable and effectively reducing the shaking phenomenon of the engine.

[0080] II. Ship berthing idling:

[0081] During the period of berthing, the main engine is in idle state, mainly to maintain the basic equipment such as power supply, the speed is generally 30-50 revolutions per minute (depending on the type and size of the ship). Even in the idle state, the addition of a small amount of hydrogen-oxygen mixed gas can optimize the combustion process. If the fuel is not fully combusted at idle, more carbon monoxide and sulfur oxides and other pollutants will be produced. Hydrogen in hydrogen-oxygen mixed gas can accelerate the combustion reaction, making fuel combustion more complete and reducing pollutant emissions. Carbon monoxide emissions can be reduced by about 10%-15%, and sulfur oxide emissions can also be reduced, which helps to improve air quality around the port and reduce environmental pollution.

[0082] In the low speed range, only a small amount of hydrogen-oxygen mixed gas is needed to assist combustion, stabilize engine operation, reduce vibration and reduce pollutant emissions, so in the low speed operating condition, the controller 10 controls the electrolysis current of the electrolysis zone 30 to the first preset current value.

[0083] The medium speed operating condition mainly includes the normal cruising condition of the ship. When the ship is cruising normally, the speed of the main engine is usually 100-200 revolutions per minute (depending on the type and size of the ship). Increasing the supply of hydrogen-oxygen mixed gas has a significant effect on improving fuel economy. During cruising, fuel consumption is a key part of ship operating costs. Oxygen in hydrogen-oxygen mixed gas can promote more uniform mixing of fuel and air, and the rapid combustion characteristics of hydrogen can accelerate the combustion reaction, greatly improving the efficiency of fuel energy release. For example, for a medium-sized cargo ship, under normal cruising conditions, after adding an appropriate amount of hydrogen-oxygen mixed gas, fuel consumption can be reduced by about 8%-12%. This not only reduces operating costs, but also reduces dependence on fuel resources. In addition, optimizing the combustion process makes the power output of the ship's main engine more stable. The improvement of combustion efficiency avoids fluctuations in power output, reducing vibration and noise. For precision instruments and equipment on the ship, a stable operating environment can reduce failure rates and extend service life; for the crew, a quiet and comfortable working environment helps to improve work efficiency and comfort. In this operating condition, the controller 10 controls the current of the electrolysis zone 30 to the second preset current value.

[0084] High speed operating conditions mainly include:

[0085] I. High-speed sailing of the ship:

[0086] When the ship needs to sail at high speed, such as to catch up with time or to avoid bad weather, the main engine speed will rise to 200-300 rpm or even higher. At this time, the ship needs to overcome a large water resistance, and the demand for power is extremely urgent. The supply of more hydrogen-oxygen mixed gas can effectively meet this high power demand. The combustion heat of hydrogen is higher, about 142.9 kJ / g, and it can release a large amount of energy when it burns, providing strong power supplement for the main engine of the ship. At the same time, the oxygen in the hydrogen-oxygen mixed gas ensures that the fuel is fully burned, so that the power output of the main engine can be maximized.

[0087] II. Emergency acceleration of the ship:

[0088] When an emergency occurs and the ship needs to accelerate, the speed of the main engine will instantaneously increase significantly. At this time, more hydrogen-oxygen mixed gas quickly participates in combustion to provide additional and rapid energy support for the ship. The high activity and high combustion heat characteristics of hydrogen enable it to release a large amount of energy in a very short time, significantly shortening the acceleration time of the ship. After adding hydrogen-oxygen mixed gas, the time for the ship to accelerate to the specified speed can be shortened by about 0.8-1.2 seconds. And during and after the emergency acceleration, the addition of hydrogen-oxygen mixed gas ensures the stable operation of the main engine, avoiding the occurrence of adverse conditions such as sudden power drop or abnormal vibration of the main engine, greatly improving the maneuverability and safety of the ship in emergency situations.

[0089] In the high-speed working condition, the controller 10 controls the current of the electrolysis area 30 to increase to a third preset current value.

[0090] In this application, the first speed threshold is 30 rpm, the second speed threshold is 100 rpm, and the third speed threshold is 200 rpm. In other embodiments, it can also be set to other specific values according to specific needs.

[0091] In summary, when the engine speed changes, the controller 10 adjusts the electrolysis current of the electrolysis area 30 according to the ideal hydrogen-oxygen mixed gas supply amount corresponding to the current speed. By setting different speed thresholds and corresponding preset current values, the controller 10 can accurately match the hydrogen-oxygen mixed gas demand of the engine under different working conditions, ensuring that the engine can obtain the best combustion effect and power performance at different speeds. In addition, adjusting the electrolysis current according to the engine speed can avoid unnecessary energy waste. At low speed, reducing the amount of hydrogen-oxygen mixed gas generated can reduce energy consumption during electrolysis; at medium and high speed, increasing the supply of hydrogen-oxygen mixed gas can ensure that the engine obtains sufficient power while maintaining high combustion efficiency. The entire adjustment process is automatically completed by the controller 10 without the need for manual intervention, improving the intelligent level of the system and reducing the operation difficulty and complexity.

[0092] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
