Description

Technical Field

[0001] The present invention relates to the technical field of power supply or distribution systems, and in particular to a controllable fast-response hydrogen production reaction system based on slurry hydrogen storage and production materials and a use method thereof. Background Art

[0002] Hydrogen energy is rich in sources, high in energy density, clean and pollution-free, and perfectly fits the trend of green development today. In the hydrogen energy industry chain (i.e., hydrogen production, storage, transportation, hydrogen fuel and application), hydrogen production is an important link in the hydrogen energy application process. At present, the hydrogen production methods in this field include pyrolysis hydrogen production, electrolysis hydrogen production, photochemical hydrogen production, metal / water hydrogen production, biomass hydrogen production and other processes. Natural gas hydrogen production is one of the main hydrogen production methods, but this method has the disadvantages of high required temperature, low efficiency, many by-products and great harm to the environment. Although water electrolysis hydrogen production has the advantage of being environmentally friendly, it is overly dependent on electricity, which limits its application scenarios. Metal / water hydrogen production has high environmental safety, low cost and simple equipment, but the aluminum / water hydrogen production system currently used has problems such as long start-up time, slow hydrogen supply rate, poor control effect, high system design cost and low system integration. In addition, the aluminum / water hydrogen production system is subject to greater constraints in practical applications because it cannot produce hydrogen at any time, quickly and controllably.

[0003] In order to solve the technical problems of insufficient hydrogen supply and inability to adapt to the hydrogen demand of target equipment in the production of hydrogen from aluminum, a Chinese invention patent with publication number CN114291790A discloses a method and a device for controlling the production of hydrogen from aluminum. The method comprises: controlling each of the reactors to be opened in sequence, and when the reactor is opened, controlling the hydrogen production process to continue in the reactor; the opening time interval t between the i-th opened reactor and the i+1-th opened reactor i ≤A i +B i -A i+1 , where B i is the reaction period of the reaction stage in the hydrogen production process performed by the i-th opened reactor, A i The feeding cycle of the feeding stage in the hydrogen production process of the i-th opened reactor is applied to a hydrogen production device with n reactors, where n is greater than or equal to 3, to achieve the superposition of hydrogen production, and all reactors can produce hydrogen uninterruptedly, achieving the technical effect of large-scale hydrogen production and continuous hydrogen production and output. However, the joint use of multiple reactors to produce hydrogen together has technical problems such as high device cost, low volume utilization rate, and low integration. Therefore, it is necessary to design and develop a fast, controllable, low-cost and highly integrated hydrogen production reaction device to meet the dual needs of timely hydrogen supply and efficient utilization of resources.

[0004] The inventor team provided a multi-media composite slurry hydrogen storage and production material based on nano-microcrystalline metal powder and organic liquid hydride and its preparation method in the Chinese invention patent with publication number CN118598073A. This invention combines the advantages of metal powder and organic liquid hydride. By coating the metal powder in the organic liquid hydride, on the one hand, it solves the passivation problem of the metal powder surface, effectively isolates the metal powder from contact with the air, and prevents the formation of oxides; on the other hand, the heat generated by the reaction of metal and water is absorbed by the organic liquid hydride, thereby improving the mass transfer efficiency and reducing the energy loss in the heat transfer process. It is expected to replace the existing process of hydrogen production as a hydrogen production method. However, in practical applications, this kind of slurry liquid has the technical problems of being difficult to transport, low conversion rate and difficult to recover when used on a large scale. How to achieve rapid, accurate and stable delivery into the reactor under positive pressure conditions, and to achieve efficient hydrogen production at a high conversion rate in the reactor while realizing recovery is a technical problem that needs to be solved urgently.

[0005] In summary, a controllable fast-response hydrogen production reaction system based on slurry hydrogen storage and production materials is designed and provided to solve the above-mentioned technical problems existing in the prior art, which has a positive promoting effect on the further application of hydrogen energy.

DETAILED DESCRIPTION

[0025] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples. The experimental methods in the following examples without specifying specific conditions are carried out according to conventional methods and conditions, or selected according to the product specifications.

[0026] Example 1 The structure of the controllable rapid response hydrogen production reaction system based on the slurry hydrogen storage and production material of this embodiment is as follows: Figure 1 As shown, it includes a transport module, a reaction module, a recovery module, a purification module, and a hydrogen storage module. The structure of the reaction module is as follows Figure 2 As shown; its usage is as follows: S1. When the hydrogen production system is started, the multi-media composite slurry hydrogen storage and production material (metal hydride, organic liquid hydride and catalyst mixture) stored in the raw material tank 1 is injected into the reactor 3 from the feed port 304 at a feed rate of 5 g / min via the diaphragm pump 2; S2, the water in the water tank 7 enters the vaporizer 5 at a certain rate ratio (water: multi-media composite slurry hydrogen storage material = 5:1) under the start of the horizontal flow pump 6, is heated to 120 ° C and vaporized, and then is input into the reactor 3 through the water vapor inlet 307 to react with the multi-media composite slurry hydrogen storage material under the reaction conditions; the pressure gauge 301 shows 0.7 atm, the thermometer 302 shows 120 ° C, and the stirring of the 4-layer stirring paddle 306 (rotation rate is 100 rpm), the metal hydride in the multi-media composite slurry hydrogen storage and production material entering the reactor 3 first reacts with the high-temperature water vapor to rapidly undergo a hydrolysis reaction to produce hydrogen in the reactor 3, and the heat generated promotes the catalytic cracking of the organic liquid hydride to produce hydrogen, and synergistically produces a large amount of hydrogen; the generated hydrogen mixed with water vapor flows from the gas outlet 305 at the upper end of the reactor 3 to the inlet end of the membrane separator 4, and the vaporizer 5 stops vaporizing after a period of reaction, and uses the heat released by the reaction and the residual heat to continue the catalytic reaction. The heat insulation layer 303 of the reactor 3 is used to prevent heat loss so that the reaction continues; S3, after the low-purity hydrogen flow entering the membrane separator 4 is separated and purified, the high-purity hydrogen is input into the hydrogen storage tank 11 at a certain flow rate under the regulation of the flow meter 10 for storage, so as to realize rapid hydrogen production; S4. When a certain amount of hydrogen is stored in the hydrogen storage tank 11 or the process is terminated manually, the raw material tank 1 and the water tank 7 immediately stop supplying raw materials, the reactor 3 stops stirring, and hydrogen production in the reactor 3 immediately stops; the residual organic liquid after the reaction is completed enters the filter 8 through the drain port 308, and is recovered and stored in the recovery tank 9 after filtration.

[0027] Example 2 This embodiment is basically the same as Embodiment 1, with the only difference being that the feed rate of the multi-media composite slurry hydrogen storage and production material is 7 g / min, and the feed rate ratio of water to the multi-media composite slurry hydrogen storage and production material is 3.6:1, which is recorded as Operating Condition 1.

[0028] Example 3 This embodiment is basically the same as Embodiment 1, except that the feed rate of the multi-media composite slurry hydrogen storage and production material is 8 g / min, and the feed rate ratio of water to the multi-media composite slurry hydrogen storage and production material is 3.1:1, which is recorded as Operating Condition 2.

[0029] The hydrogen production rates and conversion rates of the multi-medium composite slurry hydrogen storage and production materials under different working conditions of Examples 2 and 3 were statistically analyzed. The results are as follows Figure 3 As shown in Figure 3, under the first working condition, the hydrogen production rate is stable at 12.5 SL / min, and the conversion rate of the slurry liquid is as high as 92.5%, achieving rapid, continuous and efficient hydrogen production; under the second working condition, the hydrogen production rate increases and stabilizes at 14.0 SL / min, and the conversion rate also increases to 94.7%, also achieving rapid, continuous and controllable hydrogen production.

[0030] Example 4 This embodiment is basically the same as the embodiment 1, and the only difference is that the type of feed pump is changed. This embodiment uses a gear pump, a screw pump, and a centrifugal pump for feeding, and combines the effect of the embodiment 1 to study the relationship between the feed stability under different feed pumps. The results are as follows: Figure 4 shown.

[0031] Depend on Figure 4 It can be seen that the gear pump cannot operate stably when pumping multi-media composite nano-microcrystalline aluminum-based slurry, and the gear pump can hardly work effectively in the later stage of feeding. Screw pumps and centrifugal pumps can feed continuously, but the actual flow value of the screw pump has a large deviation from the set flow value under different flow rate settings. When the centrifugal pump feeds at a large flow rate, the deviation between the actual flow rate and the set flow rate is small, but when the centrifugal pump feeds at a small flow rate, the deviation between the actual flow rate and the set flow rate is large, and the material cannot be reduced stably, and it does not have adjustability within a wide flow range. The diaphragm pump can maintain stable feeding when feeding at both large and small flow rates, and there is almost no deviation between the actual flow rate and the set flow rate.

[0032] Example 5 This example is basically the same as Example 1, except that the number of layers of stirring paddles (single layer, double layer, triple layer) is changed. In combination with Example 1, the relationship between the number of layers of stirring paddles and the residence time of the reactants is studied. The results are as follows: Figure 5 shown.

[0033] Depend on Figure 5 It can be seen that based on the special fluid mechanics properties of multi-media composite slurry hydrogen storage and production materials, with the increase of the number of agitator layers, the residence time distribution of the material in the reactor becomes narrower and narrower, and its residence time is significantly shortened, getting closer and closer to the ideal plug flow, which helps the hydrogen production reaction to proceed faster and more efficiently.

[0034] Example 6 This embodiment is Example 1. After the hydrogen production reaction, the upper and lower layers of the multi-media composite slurry hydrogen storage and production material in the reactor were subjected to SEM morphology characterization to observe the changes in the particle morphology in the slurry after the reaction. The results are as follows: Figure 6 shown.

[0035] Depend on Figure 6 It can be seen that the particles in the slurry are all spherical particles with uniform particle size distribution. After the reaction, the small-sized particles in the slurry adhere to the large-sized particles, the spherical particles have obvious agglomeration, and the particle size of the particles in the upper slurry is slightly smaller than that of the particles in the lower slurry, which means that the slurry after the reaction can achieve rapid solid-liquid separation. And under the action of the separator, most of the slurry liquid after the reaction is recovered.

[0036] Example 7 This embodiment is basically the same as step S1 in embodiment 1, except that the feed rate of the multi-media composite slurry hydrogen storage and production material is 10 g / min, and the continuous feeding is 120 min. The weight reduction of the slurry tank is monitored by an electronic balance to verify the stability of the slurry pump. The results are as follows: Figure 7 shown.

[0037] Depend on Figure 7 It can be seen that in the first 60 minutes of operation, the actual feed amount of the slurry pump is almost completely consistent with the theoretical feed amount. After 60 minutes, there is a slight deviation between the actual feed amount and the theoretical feed amount, but it does not affect the smooth feeding of the feed pump. This means that under the action of the diaphragm pump, the hydrogen production reaction system provides controllable and continuous feeding for the multi-media composite nano-microcrystalline aluminum-based slurry.

[0038] In summary, the hydrogen production reaction system of the present invention is based on the hydrogen production reaction of multi-media composite slurry hydrogen storage material and water, and uses the synergistic effect of different types of feed pumps and multi-stage stirring paddles to shorten the start-up time of the aluminum water hydrogen production reaction, reduce the residence time of the reactants, improve the fluidity of the slurry liquid, and improve the hydrogen production conversion rate and stability. At the same time, it can stop the reaction immediately, react again after stopping, and recycle the slurry liquid after the reaction, which greatly reduces the loss of resources, improves energy utilization, and eliminates the safety hazards caused by excess hydrogen. In addition, the system has a simple and compact structure, is easy to operate, has a low design cost, and has a high degree of integration.

[0039] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
