Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic structural diagram of a renewable energy hydrogen production and storage system provided by an embodiment of the present invention is shown, and the system includes a renewable energy power generation subsystem 100, a water electrolysis hydrogen production subsystem 200, a heat tracing subsystem 300, and an organic matter storage subsystem 400.
The renewable energy power generation subsystem 100 is configured to convert renewable energy into electric energy, and provide the obtained electric energy to the water electrolysis hydrogen production subsystem 200.
The renewable energy power generation subsystem 100 mainly includes a renewable energy power generation device 101 and a converter 102.
For example, the renewable energy power generation device 101 may be a photovoltaic power generation device, a wind power generation device, or the like.
The converter 102 is used for converting the voltage output by the renewable energy power generation device 101 and then providing a working power supply for the water electrolysis hydrogen production subsystem 200.
And the water electrolysis hydrogen production subsystem 200 is used for electrolyzing water to obtain hydrogen and oxygen and conveying the hydrogen to the organic matter hydrogen storage subsystem 400.
The water electrolysis hydrogen production subsystem 200 mainly comprises a water electrolysis hydrogen production device 201, a hydrogen storage tank 202 and an oxygen storage tank 203. The water electrolysis hydrogen production device 201 can be an electrolytic bath and is used for electrolyzing water to obtain hydrogen and oxygen, and delivering the hydrogen to the hydrogen storage tank 202 for storage so as to provide the hydrogen to a later-stage subsystem; meanwhile, the oxygen is delivered to the oxygen storage tank 203 for storage, and the oxygen in the oxygen storage tank 203 can be directly provided to the oxygen user.
The organic hydrogen storage subsystem 400 is configured to react hydrogen with an organic substance to obtain a hydrogenated organic substance, that is, store hydrogen obtained by the water electrolysis hydrogen production subsystem 200 into an organic hydrogen storage medium.
In one embodiment of the present application, the organic hydrogen storage medium includes, but is not limited to, an organic unsaturated compound such as an alkene, alkyne, or aromatic hydrocarbon, and the like.
After the hydrogen is stored in the organic hydrogen storage medium, the subsequent storage and transportation of the hydrogen are facilitated. And the organic matter has high hydrogen storage density, and compared with a high-pressure gaseous transportation mode, the transportation cost of hydrogen is reduced.
The heat tracing subsystem 300 is connected between the water electrolysis hydrogen production subsystem 200 and the organic matter hydrogen storage subsystem 400.
The heat tracing subsystem 300 is mainly used for transferring part of heat generated when the organic hydrogen storage subsystem 400 generates reaction products to the water electrolysis hydrogen production subsystem 200, so that the temperature of the water electrolysis hydrogen production device is increased.
In winter in northern China, the temperature of the external environment is very low, which may cause freezing and crystallization of wading equipment (such as an electrolytic bath) and liquid (such as electrolyte, water and the like) in a pipeline in the water electrolysis hydrogen production subsystem 200. Meanwhile, the organic hydrogen storage subsystem 400 generates a large amount of heat when hydrogen is added to the organic hydrogen storage medium to perform a chemical reaction to generate a reaction product. On the other hand, in order to avoid freezing and crystallization of the liquid in these apparatuses, it is necessary to keep the liquid in these apparatuses at a constant temperature by performing heat-insulating treatment. The heat tracing subsystem 300 is used for heating the relevant equipment in the water electrolysis hydrogen production subsystem 200 by using the heat generated by the organic hydrogen storage subsystem 400, so that the relevant equipment in the subsystem is maintained at a certain temperature.
The control process of the system is described below by taking renewable energy as light energy, such as photovoltaic off-grid hydrogen production, as an example:
in the daytime, the photovoltaic off-grid power generation subsystem generates power, the output power is supplied to the water electrolysis hydrogen production subsystem 200 for water electrolysis hydrogen production, the generated hydrogen is stored in the hydrogen storage tank 202, and part of the generated hydrogen is conveyed to the organic matter hydrogen storage subsystem 400. In the organic hydrogen storage subsystem 400, hydrogen chemically reacts with the organic hydrogen storage medium to generate a reaction product and simultaneously generates a large amount of heat, and the heat is taken away by cooling water. A portion of the hydrogen continues to be stored in the hydrogen storage tank 202.
At night, the photovoltaic off-grid power generation subsystem does not work, so the water electrolysis hydrogen production subsystem also stops working at night, the temperature of the electrolyte and the water system is reduced, and particularly at night in winter, the electrolyte and water can be crystallized and frozen to cause accidents. Under the scene, hydrogen stored in the hydrogen storage tank 202 is continuously conveyed to the organic hydrogen storage subsystem 400 to carry out chemical reaction with the organic hydrogen storage medium to generate reaction products and simultaneously generate a large amount of heat, and the heat is transferred to the water electrolysis hydrogen production device in the water electrolysis hydrogen production subsystem 200 by the heat tracing subsystem to be heated, so that the electrolyte and water in the water electrolysis hydrogen production subsystem are maintained within a certain temperature range, and freezing and crystallization are avoided. And when the water electrolysis hydrogen production subsystem is started up again, the water electrolysis hydrogen production subsystem can be started up quickly, the starting-up time is shortened, the energy consumption is reduced, and the hydrogen production efficiency of the water electrolysis hydrogen production subsystem is further improved.
In addition, the water electrolysis hydrogen production device is heated by the heat generated by the organic hydrogen storage subsystem, the temperature of reaction products can be reduced, and the usage amount of cooling media required for cooling the reaction products is reduced, namely the amount of cooling water is reduced.
The renewable energy hydrogen production and storage system comprises a renewable energy power generation subsystem, a water electrolysis hydrogen production subsystem, a heat tracing subsystem and an organic matter hydrogen storage subsystem, wherein the heat tracing subsystem is connected between the organic matter hydrogen storage subsystem and the water electrolysis hydrogen production subsystem, and partial heat generated when the organic matter hydrogen storage subsystem generates hydrogenated organic matters is transferred to the water electrolysis hydrogen production subsystem through the heat tracing subsystem to heat a water electrolysis hydrogen production device. The scheme utilizes the heat generated when hydrogen is added into the organic hydrogen storage medium to heat the water electrolysis hydrogen production device, and ensures that the liquid in the device can not be frozen and crystallized in cold seasons. The safety of the system is guaranteed, and meanwhile, the next starting time is reduced, namely, the production efficiency of the water electrolysis hydrogen production device is improved. Meanwhile, the cooling water consumption of the organic hydrogen storage subsystem for cooling the hydrogenated organic is reduced, and the energy utilization rate of the system is improved.
Referring to fig. 2, a schematic structural diagram of another renewable energy hydrogen production and storage system according to an embodiment of the present invention is shown, and the operation of the heat tracing subsystem will be described in detail in this embodiment.
As shown in FIG. 2, the heat tracing subsystem 300 basically includes: a first heat exchanger 301, a tracing water pump 302, a tracing water tank 303, and a first flow control valve 304.
The water inlet of the first heat exchanger 301 is connected with one end of a first flow control valve 304, the other end of the first flow control valve 304 is connected with the water outlet of the heat tracing water pump 302, the water inlet of the heat tracing water pump 302 is connected with the water outlet of the heat tracing water tank 303, the water inlet of the heat tracing water tank 303 is connected with the heat exchange water outlet of the water electrolysis hydrogen production device 201, and the heat exchange water inlet of the water electrolysis hydrogen production device 201 is connected with the water outlet of the first heat exchanger 301.
The first heat exchanger 301 exchanges heat with the reaction product generated by the organic hydrogen storage subsystem 400 by using the input cooling water, so that the cooling water absorbs heat and is changed into heat tracing water, namely hot water; then, the first heat exchanger 301 delivers the heat tracing water to the low-temperature electrolyte and water system in the water electrolysis hydrogen production device 201 for heat exchange, and the heat tracing water is changed into cooling water (i.e., heat tracing backwater), and the heat tracing backwater flows into the heat tracing water tank 303. The cooling water in the heat tracing water tank 303 is conveyed to the first heat exchanger 301 again by the heat tracing water pump 302, and thus, the cooling water circulation process of the heat tracing subsystem is completed.
The first flow control valve 304 is used for controlling the amount of cooling water entering the first heat exchanger 301, so as to control the heat exchange speed of the first heat exchanger 301, further adjust the temperature of the heat tracing water, and maintain the stable operation of the heat tracing water pump 302.
In general, the heat generated by the reactant generated by the organic hydrogen storage subsystem 400 is large, and the hydrogen production apparatus 201 by water electrolysis is not enough to be consumed, in this case, in order to ensure the temperature stability of the finally obtained reaction product, a second heat exchanger is arranged in the organic hydrogen storage subsystem 400 for controlling the temperature of the reaction product. Meanwhile, in order to maintain the temperature of the water electrolysis hydrogen production apparatus 201 stable, the flow rate of the hydrogenated organic matter flowing through the first heat exchanger 301 needs to be controlled, that is, the heat quantity involved in the heat exchange in the first heat exchanger 301 needs to be controlled, so as to maintain the temperature of the heat tracing water.
As shown in fig. 2, the organic hydrogen storage subsystem 400 mainly includes: a hydrogenation reactor 401, a second heat exchanger 402, a cooling device 403, a second temperature controller 404, a third flow control valve 405, a hydrogenated organic matter storage tank 406, a first temperature controller 407 and a second flow control valve 408.
In this embodiment, the second flow control valve 408 is used to control the flow of the hydrogenated organic matter flowing through the cross line connected in parallel with the first heat exchanger 301, so as to control the flow of the hydrogenated organic matter flowing through the first heat exchanger 301.
The hydrogenation reactor 401 is configured to perform a chemical reaction between hydrogen and an organic hydrogen storage medium to generate a corresponding reaction product, i.e., a hydrogenated organic substance.
The first temperature controller 407 is disposed at the water outlet of the first heat exchanger 301, and the second flow control valve 408 is disposed on the crossover line connecting the hydrogenation reactor 401 and the second heat exchanger 302.
The first temperature controller 407 is configured to detect a water temperature at the water outlet of the first heat exchanger 301, and control an opening degree of the second flow control valve 408 according to the detected water temperature, so as to adjust a flow rate of a reaction product entering the first heat exchanger 301, that is, to control an amount of the reaction product participating in a heat exchange process of the first heat exchanger 301, that is, to control heat participating in the heat exchange of the first heat exchanger 301, and finally to maintain a temperature of the heat tracing water within a first preset temperature range. The temperature of the heat tracing water can be flexibly controlled through the first temperature controller and the second flow control valve.
The second heat exchanger 402 is disposed between the first heat exchanger 301 and the hydrogenated organic material storage tank 406.
A part of the reaction product passes through the first heat exchanger 301 and then enters the second heat exchanger 402, and the rest of the reaction product directly enters the second heat exchanger 402. That is, a part of the reaction product is heat-exchanged via the first heat exchanger 301 and the second heat exchanger 402; another portion of the reaction product is heat exchanged only through the second heat exchanger 402. The reactant flow rates of the two branches are controlled by adjusting the opening degree of the second flow control valve 408.
The water inlet of the second heat exchanger 402 is connected to the water outlet of the cooling device 403 via a third flow rate control valve 405, and the water outlet of the second heat exchanger 402 is connected to the water inlet of the cooling device 403.
The cooling device 403 provides cooling water to the second heat exchanger 402, the cooling water exchanges heat with the reaction product passing through the second heat exchanger 402 to reduce the temperature of the reaction product, and the heat exchanged water (i.e., cooling return water) flows back to the cooling device 403 to be cooled and then is provided to the second heat exchanger 402 again.
The amount of cooling water entering the second heat exchanger 402 is controlled by a third flow control valve 405. Wherein, the opening degree of the third flow control valve 405 is controlled according to the temperature of the reaction product output by the second heat exchanger 402 measured by the second temperature controller 404, so as to maintain the final temperature of the reaction product within a second preset temperature range.
The hydrogenated organic output from the second heat exchanger 402 is sent to a hydrogenated organic storage tank 406 for storage and transportation to the site of the hydrogen user.
In one embodiment of the present application, the system further includes a dehydrogenation unit 500. After the reaction product output by the organic hydrogen storage subsystem 400 is transported to a hydrogen user, dehydrogenation is performed by using the dehydrogenation device 500, that is, hydrogen is obtained from the reaction product and is used by the hydrogen user. The dehydrogenated organic may be re-delivered to the organic hydrogen storage subsystem 400 as an organic hydrogen storage medium.
According to the renewable energy hydrogen production and storage system provided by the embodiment, partial heat generated by the organic matter hydrogen storage subsystem is transferred to the water electrolysis hydrogen production subsystem by the first heat exchanger to heat the water electrolysis hydrogen production device, so that liquid crystallization and congealing in the water electrolysis hydrogen production device are avoided. Meanwhile, the temperature of the hydrogenated organic matters output by the organic matter hydrogen storage subsystem is stabilized by utilizing the second heat exchanger. And controlling the temperature of the heat tracing water in the heat tracing subsystem to be stabilized within a certain range by using the first temperature controller and the second flow control valve. The system can effectively utilize the heat in the system, and the energy utilization rate is improved.
Referring to fig. 3, a schematic structural diagram of another renewable energy hydrogen production and storage system provided in the present invention is shown, and this embodiment is applied to a wind power generation application scenario.
In the wind power generation application scene, the difference with the embodiment shown in fig. 2 is that no matter day or night, only the wind power generation device can generate electric energy, and the water electrolysis hydrogen production subsystem can work, namely heat preservation is not needed. The photovoltaic power generation device can only generate power in the daytime and cannot generate power at night, so that the working state of the heat tracing subsystem cannot be controlled in the daytime or at night in the application scene of wind power generation.
In a wind power generation application scenario, the water electrolysis hydrogen production device 201 in the water electrolysis hydrogen production subsystem 200 is further provided with a third temperature controller 204.
