Technical Field

[0001] The present application relates to the field of internal combustion engine power systems, and in particular to a slurry hydrogen storage and production internal combustion engine power system based on in-situ acquisition of seawater and a method of using the same. Background Art

[0002] Marine economy is an important aspect of national strategy. As an important support for marine economy, ocean shipping industry is playing an increasingly important role. As a carrier of global cargo transportation, ocean-going ships play a pivotal role in it. As the source of transportation power for ships, the performance of internal combustion engine power system is directly related to navigation efficiency, transportation cost and environmental protection. At present, the internal combustion engines of ocean-going ships are mainly divided into diesel engines and gasoline engines. Among them, diesel engines occupy a dominant position in ship power systems due to their high thermal efficiency and reliability. With my country's "carbon peak and carbon neutrality" goals and the background of energy conservation and emission reduction, the use of green renewable energy to replace the original fossil energy in new internal combustion engine power systems is an effective measure to promote the development of "green shipping". Hydrogen energy is currently the most ideal clean energy. The product is only water, which can be recycled and has high heat of combustion. It is an ideal new fuel. However, the storage and transportation of hydrogen energy limits the development of hydrogen energy. The relatively mature high-pressure gaseous hydrogen storage technology has a small hydrogen storage capacity and cannot be promoted on a large scale. The liquid organic hydrogen carrier has poor absorption and dehydrogenation kinetics.

[0003] At present, in order to improve the hydrogen storage capacity and controllability of hydrogen storage and production, slurry hydrogen storage and production materials have emerged, which include organic liquid hydrogen storage materials, metal materials, catalysts and other components. For example, CN118598072A discloses a multi-medium composite slurry hydrogen storage and production material and a preparation method thereof, wherein the multi-medium composite slurry hydrogen storage and production material includes nano-microcrystalline metal powder, coordinated hydride and organic liquid hydride. By utilizing the hydrothermal characteristics of nano-microcrystalline metal powder and coordinated hydride and the catalytic effect of coordinated hydride, the amount of hydrogen released under low temperature conditions is increased, and an efficient and controllable hydrogen storage and production process of multi-medium composite slurry hydrogen storage and production materials is achieved. However, how to use slurry hydrogen storage and production materials in internal combustion engine power systems is a problem that urgently needs to be solved. Summary of the invention

[0020] The following combination Figure 1 This application is described in further detail.

[0021] Example 1 Example 1 of the present application discloses a slurry hydrogen storage and production internal combustion engine power system based on in-situ acquisition of seawater.

[0022] Reference Figure 1, a slurry hydrogen storage and production internal combustion engine power system based on seawater in-situ acquisition, including a slurry storage tank 2 for storing slurry hydrogen storage and production materials, a water vapor supply module 3 for converting seawater into water vapor, a hydrogen production module 4, a hydrogen internal combustion engine 1 for receiving hydrogen output by the hydrogen production module 4 and converting the chemical energy of hydrogen combustion into mechanical energy, an oxygen storage module 5 for storing oxygen and supplying it to the hydrogen internal combustion engine 1, and a material recovery module 6 for classifying and storing residual materials after the hydrogen production reaction. When the slurry hydrogen storage and production internal combustion engine 1 power system is started, seawater is obtained through the water vapor supply module 3 and converted into water vapor and synchronously input into the hydrogen production module 4 with the slurry hydrogen storage and production materials in the slurry storage tank 2, the slurry hydrogen storage and production materials and water vapor react with hydrogen production in the hydrogen production module 4, the generated hydrogen and the oxygen output by the oxygen storage module 5 are input into the hydrogen internal combustion engine 1 together, the chemical energy of hydrogen combustion is converted into mechanical energy to provide power output, and at the same time, the residual materials generated in the hydrogen production module 4 are transported to the material recovery module 6 for classification and storage.

[0023] Reference Figure 1 The water vapor supply module 3 includes a pretreatment box 31, a sedimentation tank 32, a first filter 33, a water storage tank 34 and an electric heater 35 which are connected in sequence. After the seawater passes through the pretreatment box 31 to remove suspended matter such as silt in the seawater, it enters the sedimentation tank 32 and the filter in sequence to further remove impurities and is stored in the water storage tank 34; the sedimentation tank 32 is a secondary sedimentation tank 32, which includes two dosing bins containing alum and barium chloride respectively. When the seawater is transported to the sedimentation tank 32, alum is first added, and the sediment is allowed to stand for a period of time to remove suspended particles, colloids, algae, calcium, magnesium, and iron metal ions in the water; then barium chloride is added, and the sediment is allowed to stand for a period of time. Remove excess sulfate ions; the filter is a three-stage filter filled with quartz sand, PP cotton and activated carbon in sequence. When seawater enters the filter, it filters out sediment particles and colloids larger than 50 microns, filters out sediment particles and colloids larger than 20 microns, and filters out sediment particles and colloids larger than 20 microns in sequence, adsorbs metals and residual chlorine, and removes odor and color; the seawater that has passed through the pretreatment box 31, the sedimentation tank 32 and the filter is transported to the water storage tank 34 for storage. When the hydrogen production reaction is started, the electric heater 35 is used to convert the seawater output from the water storage tank 34 into water vapor and supply it to the hydrogen production module 4, and the concentrated seawater is directly discharged.

[0024] The water vapor and slurry hydrogen storage and production materials are transported to the hydrogen production module 4 for hydrogen production reaction. For details, refer to Figure 1The hydrogen production module 4 includes a reactor 41 for providing an environment for hydrogen production reaction, a membrane separator 42 for separating water vapor and hydrogen, and a hydrogen storage tank 43 for storing separated hydrogen. The reactor 41 is connected to the electric heater 35 and the slurry storage tank 2 respectively, and the membrane separator 42 is connected to the reactor 41 and the hydrogen storage tank 43 respectively. Further, in order to improve the uniformity of mixing of water vapor and slurry hydrogen storage material in the reactor 41, the slurry storage tank 2 is connected to the top of the reactor 41, the electric heater 35 is connected to the bottom of the reactor 41, and a dispersion plate with multiple dispersion holes is provided in the middle of the reactor 41, which improves the uniformity of mixing and increases the contact area between water vapor and slurry hydrogen storage material. In the reactor 41, the organic liquid hydrogen storage material undergoes a dehydrogenation reaction under the activation of the catalyst to release hydrogen, and the metal material undergoes a hydrolysis reaction with water vapor to produce hydrogen while releasing heat. The hydrogen generated in the reactor 41 is purified by the membrane separator 42 and stored in the hydrogen storage tank 43.

[0025] In order to recover and store other materials except hydrogen after the reaction, refer to Figure 1 The material recovery module 6 includes a second filter 61, a liquid storage tank 62 and a slag storage tank 63. The second filter 61 is used to separate the residual material after the hydrogen production reaction output by the hydrogen production module 4 into solid and liquid, and the obtained organic liquid hydrogen storage material after dehydrogenation is transported to the liquid storage tank 62, and the obtained catalyst and solid hydrolysis product are transported to the slag storage tank 63.

[0026] In order to improve the completeness of hydrogen combustion and thus improve the power output and thermal efficiency of the slurry hydrogen storage and production internal combustion engine 1 power system, refer to Figure 1 The oxygen storage module includes a liquid oxygen tank 51 and an oxygen storage tank 52. The liquid oxygen tank 51, the oxygen storage tank 52 and the internal combustion engine are connected in sequence. The liquid oxygen in the liquid oxygen tank 51 is converted into oxygen and stored in the oxygen storage tank 52 when output. Then, the oxygen is transported to the hydrogen internal combustion engine 1 through the oxygen storage tank 52 to react with the hydrogen transported by the hydrogen storage tank 43 in the hydrogen internal combustion engine 1, and the chemical energy of the hydrogen combustion is converted into mechanical energy, thereby providing power output.

[0027] Furthermore, in order to improve the heat utilization rate in the entire power system. Figure 1On the one hand, the water vapor supply module 3 also includes a first heat exchanger 36, which is connected to the water storage tank 34, the membrane separator 42 and the reactor 41. Since the hydrogen production reaction in the reactor 41 releases a large amount of heat, the water vapor temperature rises, so the water vapor separated by the membrane separator 42 in the reactor 41 is high-temperature water vapor. In contrast, the water vapor obtained by heating the seawater by the electric heater 35 is low-temperature water vapor. The first heat exchanger 36 exchanges heat between the high-temperature water vapor and the seawater output from the water storage tank 34 to the first heat exchanger 36 to obtain low-temperature water vapor, which is input into the reactor 41, and the concentrated seawater is directly discharged. On the other hand, the oxygen storage module also includes a second heat exchanger 53, which is connected to the liquid oxygen tank 51, the oxygen storage tank 52 and the internal combustion engine. The second heat exchanger 53 is used to exchange heat between the high-temperature exhaust gas output by the internal combustion engine and the liquid oxygen output by the liquid oxygen tank 51 to obtain oxygen, which is input into the oxygen storage tank 52, thereby improving the efficiency of converting liquid oxygen into oxygen. In addition, the second heat exchanger 53 is connected to the first heat exchanger 36. The second heat exchanger 53 returns the water liquefied from the high-temperature exhaust gas to the first heat exchanger 36 to generate low-temperature water vapor, and the remaining exhaust gas is directly discharged.

[0028] The implementation principle of the slurry hydrogen storage and production internal combustion engine power system based on in-situ acquisition of seawater in Example 1 of the present application is as follows: the seawater is obtained and processed in sequence through a pretreatment box 31, a sedimentation tank 32 and a first filter 33 and then stored in a water storage tank 34, and then the seawater in the water storage tank 34 is converted into water vapor through an electric heater 35 and a first heat exchanger 36 and synchronously input into a reactor 41 together with the slurry hydrogen storage and production material in a slurry storage tank 2, the separated hydrogen is input into a hydrogen internal combustion engine 1 through a membrane separator 42 to provide power output, the separated high-temperature water vapor is returned to the first heat exchanger 36 to utilize the waste heat and recycle the water, and the high-temperature exhaust gas generated by the hydrogen internal combustion engine 1 is input into a second heat exchanger 53, which, on the one hand, improves the efficiency of converting liquid oxygen into oxygen, and on the other hand, returns the water in the high-temperature exhaust gas to the first heat exchanger 36 for recycling. Under the combined effect, the use of seawater, which is easy to obtain, and slurry hydrogen storage and production materials to carry out hydrogen production reactions is conducive to the continuous and stable production of hydrogen, which can continuously and stably provide fuel for the internal combustion engine power system, meet the energy needs of the internal combustion engine, and is conducive to long-distance navigation of ships using slurry hydrogen storage and production internal combustion engine 1 power system.

[0029] Example 2 Embodiment 2 of the present application provides a method for using a slurry hydrogen storage and production internal combustion engine power system based on in-situ acquisition of seawater, comprising the following steps: in the initial stage of starting the internal combustion engine power system, seawater is obtained and processed in sequence through a pretreatment box 31, a sedimentation tank 32 and a first filter 33 and then stored in a water storage tank 34; the seawater in the water storage tank 34 is then converted into water vapor through an electric heater 35 and a first heat exchanger 36 and simultaneously input into a reactor 41 together with the slurry hydrogen storage and production material in the slurry storage tank 2; the separated hydrogen and the oxygen provided by the oxygen storage tank 52 are input into the hydrogen internal combustion engine 1 through a membrane separator 42 to provide power output; the separated high-temperature water vapor is returned to the first heat exchanger 36 to utilize the waste heat and recycle the water; the high-temperature exhaust gas generated by the hydrogen internal combustion engine 1 is input into the second heat exchanger 53, which, on the one hand, improves the efficiency of converting liquid oxygen into oxygen; on the other hand, the water in the high-temperature exhaust gas is returned to the first heat exchanger 36 for recycling.

[0030] When the temperature in the reactor 41 reaches a predetermined temperature and the internal combustion engine power system operates stably, the heating of the electric heater 35 is stopped, and the first heat exchanger 36 serves as the main steam generator, and the electric heater 35 serves as a backup steam generator. The water in the high-temperature exhaust gas and the high-temperature steam separated by the membrane separator 42 are used as raw materials for the hydrogen production reaction with the slurry hydrogen storage and production material. The heat provided by the high-temperature steam, high-temperature exhaust gas and the hydrogen production reaction converts water into steam, thereby realizing the recycling of water and heat in the power system, reducing the use cost and energy consumption, and reducing emissions.
