Description

Technical Field

[0001] This application relates to the technical field of solar energy utilization, and particularly to an energy supply system. Background Art

[0002] At present, China's development and exploration of solar energy mainly focus on directions such as photovoltaic power generation, solar thermal concentrating heating, and photovoltaic power generation coupled with direct current electrolytic hydrogen production. However, at present, the large-scale popularization and replicability of such technologies still need to be further studied, which is closely related to the fluctuating intermittency of solar energy and the reliability of energy conversion devices. In addition, the utilization of solar spectrum photons at the source by such technologies is not very sufficient. For example, in a single photovoltaic power generation process, only about 50% of the photons are absorbed and utilized, and most of the photon energy is wasted. Moreover, the parasitic waste heat caused by absorption differences affects the power generation efficiency and safety of the photovoltaic. Therefore, the development of the full-spectrum utilization of solar energy is the key research direction in the current scientific research community, aiming to improve the comprehensive utilization efficiency of solar energy.

[0003] The cascade frequency division utilization of solar energy is inseparable from the spectral absorption, transmission, refraction, reflection, etc. of optical media. Currently, it is relatively common to directly construct a solid frequency division film by coating. It can transmit solar energy in a certain wavelength band to drive the photovoltaic power generation process, and a part of the reflected photons can provide energy for reactions such as carbon dioxide hydrogenation or Fischer-Tropsch synthesis, thus constituting the coordinated production of electric energy and chemical energy. Similarly, a typical photocatalytic hydrogen production particle suspension that absorbs energy in the ultraviolet light region can also be used as an excellent optical frequency division device. The energy transmitted through this device can excite the photo-generated electrons and holes in the photovoltaic device to form an energy potential difference and form a stable voltage output. In this way, a combined supply system of hydrogen energy and electric energy driven by the full solar spectrum can be constructed. However, for a micro-nano particle working medium such as a photocatalyst, its particle interface surface energy is very high, and obvious sedimentation and particle aggregation will occur during the reaction process or when flowing in a tube flow reactor. Of course, when the system does not work due to cloudy days or rainy days, the particle group will also undergo obvious coagulation and adhere to the inner side of the pipe wall. When the system is restarted, it is still very difficult to return to the original uniformly dispersed state and frequency division effect. Therefore, for such special working conditions, how to realize the cyclic regeneration and high-dispersion reuse of the reaction material working medium is very crucial. Summary of the Invention

The heat exchanger includes a first flow path and a second flow path, and heat exchange can be carried out between the first flow path and the second flow path.

The second reaction chamber, the second pump, the second liquid storage tank, and the first flow path are connected end to end to form a second loop.

[0026] As Figure 1 shown, the energy supply system according to an embodiment of the present application includes a concentrator 10, a reactor 20, a first liquid storage tank 30, a first pump body 40, a second pump body 50, a second liquid storage tank 60, a heat exchanger 70, a third liquid storage tank 90, a heat supply chamber 100, and at least one evaporation tank 110. The concentrator 10 and the reactor 20 are relatively spaced apart in the vertical direction. The reactor 20 includes a first reaction chamber 21 and a second reaction chamber 22. The heat exchanger 70 includes a first flow path and a second flow path, and heat exchange can be carried out between the first flow path and the second flow path. The first reaction chamber 21 and the first liquid storage tank 30 are connected end to end to form a first loop, and a first pump body 40 is connected between the first reaction chamber 21 and the first liquid storage tank 30. The second reaction chamber 22, the second pump body 50, the second liquid storage tank 60, and the first flow path are connected end to end to form a second loop. The second flow path, the third liquid storage tank 90, and the heat supply chamber 100 are connected end to end to form a third loop. The evaporation tank 110 is disposed opposite to the heat supply chamber 100. The first liquid storage tank 30 is used to store the photocatalyst particle suspension.

[0027] Specifically, the concentrator 10 is used to converge solar rays. The first liquid storage tank 30 is used to store the photocatalyst particle suspension. The first pump 40 can drive the photocatalyst particle suspension into the first reaction chamber 21, where a photocatalytic reaction occurs under the action of the solar rays converged by the concentrator 10 to generate hydrogen. The photocatalyst particle suspension is in a semi-full state in the first liquid storage tank 30. The generated hydrogen enters the first liquid storage tank 30 through the first loop from the first reaction chamber 21 for storage to supply energy to the hydrogen fuel cell of the end user. The second liquid storage tank 60 is used to store the heat conversion particle suspension, which is driven by the second pump 50 into the second reaction chamber 22 to absorb the heat of the solar rays. The heat conversion particle suspension after heat conversion flows through the first flow path in the heat exchanger 70. The heat storage medium stored in the third liquid storage tank 90 enters the second flow path to exchange heat with the heat conversion particle suspension after heat conversion in the first flow path, fully absorbing the heat of the heat conversion particle suspension after heat conversion. After exchanging heat with the heat storage medium, the heat conversion particle suspension flows out of the first flow path and then returns to the second reaction chamber 22 through the second loop for re-heat conversion to absorb solar heat energy. After absorbing heat, the heat storage medium enters the heating chamber 100 to generate heat. The evaporation box 110 is arranged opposite to the heating chamber 100 and can heat and dry the materials in the evaporation box 110. When inevitable particle aggregation and sedimentation occur in the photocatalyst particles, heat conversion particles or heat storage medium, the materials are taken out from the first liquid storage tank 30, the second liquid storage tank 60 or the third liquid storage tank 90 and placed into the evaporation box 110 for evaporation and drying treatment. Then, they can be broken or stirred by themselves and re-prepared into a solution for secondary use, and re-filled into the first liquid storage tank 30, the second liquid storage tank 60 or the third liquid storage tank 90 to complete the corresponding reaction and energy conversion process, thereby using the solar heat waste to reprocess and utilize the photocatalyst particles, heat conversion particles or heat storage medium, improving the overall energy efficiency and integration of the energy supply system.

[0028] In some embodiments, a third pump is provided on the third loop. After absorbing heat, the heat storage medium enters the heating chamber 100 to generate heat under the pumping action of the third pump. Among them, the third pump can be arranged between the third liquid storage tank 90 and the second flow path, or between the second flow path and the heat exchanger 70, or between the heat exchanger 70 and the third liquid storage tank 90, and can be set according to needs and the power required for the circulation of the heat storage medium.

[0029] It should be noted that the photocatalyst particle suspension mainly consists of photocatalytic hydrogen production semiconductor materials with ultraviolet light response such as TiO2, C3N4, Cu2O, CdS, etc.; in some specific embodiments, the thermal conversion particle suspension is a particle suspension composed of particles such as Cu, graphene oxide, carbon black, etc. suspended in pure water. Its main function is to absorb solar photons in the infrared region and convert them into its own sensible heat. The flow rate and the flow pressure in the second reaction chamber 22 can be controlled by the second pump body 50; in some specific embodiments, the heat storage medium stores a hybrid working fluid nanofluid of CuO nanoparticles and K2CO3 or Li2CO3 or Na2CO3. Its material working fluid has a high specific heat capacity and can fully transfer the sensible heat of the thermal conversion particle suspension through the heat exchanger 70.

[0030] Under the action of light, the photocatalyst particle suspension absorbs the light energy of solar energy, stimulates electrons to transition from the valence band to the conduction band, forming electron-hole pairs. These electrons and holes participate in reduction and oxidation reactions respectively, generating hydrogen and oxygen. Specifically, the electrons on the surface of the photocatalyst react with water molecules to produce hydrogen, while the holes react with water molecules to produce oxygen, thus realizing the conversion of solar energy into chemical energy. Among them, the photocatalyst particle suspension releases energy during the process of decomposing water to produce hydrogen, which belongs to an exothermic reaction.

[0031] It can be understood that the light absorption range of the photocatalyst nanoparticle suspension is different from that of the thermal conversion particle suspension, which can improve the absorption utilization rate of the solar spectrum, reasonably allocate and utilize the solar spectrum energy, and thus achieve efficient energy conversion.

[0032] In some specific embodiments, the light absorption range of the photocatalyst nanoparticle suspension is 280nm - 420nm, for example, 280nm, 290nm, 300nm, 310nm, 320nm, 330nm, 340nm, 350nm, 360nm, 370nm, 380nm, 390nm, 400nm, 410nm, and 420nm, etc.; the light absorption range of the thermal conversion particle suspension is 1200nm - 2500nm, for example, 1200nm, 1300nm, 1400nm, 1500nm, 1600nm, 1700nm, 1800nm, 1900nm, 2000nm, 2100nm, 2200nm, 2300nm, 2400nm, and 2500nm, etc.

[0033] In addition, heat exchange can be carried out between the first flow path and the second flow path. In some specific embodiments, the first pipeline defines the first flow path, the second pipeline defines the second flow path, the first pipeline and the second pipeline, the heat storage medium and the heat-converted heat-converted particle suspension enter from both ends of the heat exchanger 70 respectively, and flow in the same direction in the heat exchanger 70, and then exit from the other end. That is to say, the first pipeline and the second pipeline are arranged in parallel, and can be arranged in parallel or wound around each other; in some embodiments, the heat storage medium and the heat-converted heat-converted particle suspension enter from both ends of the heat exchanger 70 respectively, but flow in opposite directions inside, and higher heat exchange efficiency can be obtained.

[0034] Since the photocatalyst particle suspension releases energy during the process of decomposing water to generate hydrogen, which is an exothermic reaction, according to the energy supply system of the embodiments of the present application, the first reaction chamber 21 penetrates through the second reaction chamber 22. In this way, while the heat-converted particle suspension in the second reaction chamber 22 absorbs the solar spectrum energy, it can also absorb the heat generated by the reaction in the first reaction chamber 21, increasing the heat exchange area between the second reaction chamber 22 and the first reaction chamber 21, thereby realizing the heat exchange between the photocatalyst particle suspension and the heat-converted particle suspension, improving the heat conversion efficiency of the heat-converted particle suspension in the second reaction chamber 22, effectively improving the heat exchange performance of the first reaction chamber 21 and the second reaction chamber 22. At the same time, the spectral regions absorbed by the photocatalyst particle suspension and the heat-converted particle suspension are different, so that the heat-converted particle suspension first absorbs the corresponding region of the spectrum and then passes through the photocatalyst particle suspension, which can ensure the effective utilization of the solar spectrum energy.

[0035] Among them, the radial cross-sectional shape of the first reaction chamber 21 includes but is not limited to square, rectangle, triangle, ellipse, and polygon (more than four sides), etc.; the radial cross-sectional shape of the second reaction chamber 22 includes but is not limited to square, rectangle, triangle, ellipse, and polygon (more than four sides), etc.

[0036] As Figure 1 shown, in some embodiments, the radial cross-sectional shape of the first reaction chamber 21 is circular, the radial cross-sectional shape of the second reaction chamber 22 is circular, and the radial cross-sectional contour of the first reaction chamber 21 and the radial cross-sectional contour of the second reaction chamber 22 form concentric circles. It can be understood that such a setting can reduce the volume of the reactor 20 while meeting the heat exchange efficiency of the first reaction chamber 21 and the second reaction chamber 22, thereby reducing the space volume occupied by the reactor 20.

[0037] In some embodiments, the evaporation tank 110 can be arranged on the side, below or above the heating chamber 100, and can be arranged according to needs.

[0038] As Figure 1As shown in the figure, for the energy supply system according to the embodiments of the present application, the number of evaporation tanks 110 is at least one, and at least one evaporation tank 110 is located directly above the heat supply chamber 100.

[0039] It can be understood that the evaporation tank 110 is arranged directly above the heat supply chamber 100 based on enhancing the heat exchange efficiency between the evaporation tank 110 and the heat supply chamber 100. When the evaporation tank 110 is arranged directly above the heat supply chamber 100, the heat transfer path is the shortest and the heat transfer efficiency is high. If the evaporation tank 110 is arranged on the side of the heat supply chamber 100, the heat of the heat supply chamber 100 needs to be transferred horizontally first and then vertically to the evaporation tank 110, and the heat transfer process is more complex, and some radiant heat will be directly dissipated to the surrounding environment.

[0040] Among them, at least one evaporation tank 110 is located directly above the heat supply chamber 100, and the number of evaporation tanks 110 is one or more. For example, the number of evaporation tanks 110 is two, three, four, five, etc., and it needs to be set according to the volume specifications of the heat supply chamber 100 and the volume specifications of the evaporation tank 110. For example, in a specific embodiment, at least one of the evaporation tanks 110 is a high-speed evaporation tank 110, and at least one other evaporation tank 110 is a low-speed evaporation tank 110. The high-speed evaporation tank 110 adopts a smaller evaporation cavity, a high-speed rotating evaporation rotor, and uses centrifugal force to promote the rapid evaporation of the liquid; the low-speed evaporation tank 110 adopts a larger evaporation cavity and a stirring device with a lower rotation speed, and uses natural convection to promote the evaporation of the liquid. Setting the heat supply chamber 100 directly below the high-speed evaporation tank 110 and the low-speed evaporation tank 110 can assist the high-speed evaporation tank 110 and the low-speed evaporation tank 110 in liquid evaporation. Among them, the high-speed evaporation tank 110 can meet the high-speed evaporation of photocatalyst particles, heat conversion particles or heat storage media, and the low-speed evaporation tank 110 can meet the low-speed evaporation of photocatalyst particles, heat conversion particles or heat storage media, so that the end user can adaptively select according to needs, improving the selectable diversity of the energy supply system, being able to adaptively meet the needs of users, and assisting the energy supply system in stable operation and efficient energy conversion.

[0041] In the actual application process, due to the heat exchange process, the temperature of the heat storage medium inside the heat supply chamber 100 gradually decreases from left to right. When there are multiple evaporation tanks 110, the heat exchange efficiency of the heat supply chamber 100 for the evaporation tanks 110 arranged from left to right is different.

[0042] Such as Figure 1As shown, the energy supply system according to an embodiment of the present application further includes at least one auxiliary heater 120. The auxiliary heater 120 is adjacent to the heat supply chamber 100, and the auxiliary heater 120 is used to heat the heat supply chamber 100. In this way, the auxiliary heater 120 can be used to perform corresponding electric heating assistance on the heat supply chamber 100, and the heating efficiency of the heat supply chamber 100 for the evaporation box 110 can be assisted and improved.

[0043] As Figure 1 shown, in some embodiments, there are multiple auxiliary heaters 120, and the heating ranges of the multiple auxiliary heaters 120 are not exactly the same. In this way, the respective heating temperature ranges can be flexibly adjusted, and the heating efficiency of the heat supply chamber 100 for the evaporation box 110 can be assisted and improved. Among them, the auxiliary heater 120 includes at least one low-temperature auxiliary heater 120 and one high-temperature auxiliary heater 120. The temperature control range corresponding to the low-temperature auxiliary heater 120 is 30 o °C - 80 o °C. For example, 30 o °C, 40 o °C, 50 o °C, 60 o °C, 70 o °C, and 80 o °C, etc. The temperature control range corresponding to the high-temperature auxiliary heater 120 is 60 o °C - 200 o °C. For example, 60 o °C, 70 o °C, 80 o °C, 90 o °C, 100 o °C, 110 o °C, 120 o °C, 130 o °C, 140 o °C, 150 o °C, 160 o °C, 170 o °C, 180 o °C, 190 o °C, and 200 o °C, etc.

[0044] In a specific embodiment, the maximum temperature of the heat supply chamber 100 can reach 90 o °C.

[0045] As Figure 1As shown, in some embodiments, the energy supply system further includes a grinding stirrer 130 configured to grind the material dried by the evaporation tank 110. After the photocatalyst particles, heat conversion particles or heat storage medium are evaporated and dried in the evaporation tank 110, the photocatalyst particles, heat conversion particles or heat storage medium particles can be transferred to the grinding stirrer 130 for further particle size refinement and uniform dispersion treatment, obtaining a more uniform particle size distribution and further enhancing the activity of the photocatalyst, heat conversion particles or heat storage medium.

[0046] It should be noted that appropriate grinding media and container materials need to be selected to avoid contaminating the material to be ground; the grinding time and rotation speed also need to be appropriately controlled to avoid structural changes caused by over-grinding.

[0047] Exemplarily, the particle size range of some grinding balls is 1mm - 20mm. For example, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, and 20mm, etc. The size of the appropriate grinding balls can be selected according to the actual working effect of the material working medium.

[0048] As Figure 1 As shown, in some embodiments, the energy supply system further includes an acoustic ultrasonic device 140 configured to disperse the material ground by the grinding stirrer 130.

[0049] Specifically, the acoustic ultrasonic device 140 can destroy and disperse the material structure by generating high-frequency ultrasonic waves. The ultrasonic waves will cause relative movement between the material particles, carefully destroying the internal structure of the material, thereby breaking the internal structure and aggregation state of the material, and can further restore the occurrence form of the material particles (photocatalyst particles, heat conversion particles or heat storage medium particles) in the liquid phase matrix, and then enhance the activity of the material particles. The material processed by the acoustic ultrasonic device 140 can be re-injected into the first liquid storage tank 30, the second liquid storage tank 60 or the third liquid storage tank 90 for repeated use and continuous and stable hydrogen and electricity complementary output.

[0050] In some embodiments, the working frequency of the acoustic ultrasonic device 140 is 100Hz - 200000Hz, and the base liquid that can be placed inside includes pure water, oil, etc., substances that are resistant to a certain temperature range and stable.

[0051] As Figure 1As shown in the figure, the energy supply system according to an embodiment of the present application further includes a concentrating photovoltaic 150 and an electricity storage device 160. The concentrating photovoltaic 150 is disposed below the reactor 20 and is spaced apart from the reactor 20 relatively. The concentrating photovoltaic 150 is electrically connected to the electricity storage device 160.

[0052] Specifically, after the solar energy passes through the reactor 20, a part of the visible light and infrared light that penetrate the reactor 20 are radiated to the concentrating photovoltaic 150 to generate direct current electricity, and the electricity is stored in the electricity storage device 160, so as to provide electricity for end users. By using the concentrating photovoltaic 150, the utilization rate of solar energy can be improved. At the same time, the turbulent flow effect on the particle suspension in the reactor 20 can effectively alleviate the processes such as agglomeration and coalescence of the particle group during the reaction process, and improve the light absorption rate of the suspension and the photon distribution uniformity on the concentrating photovoltaic 150. Among them, the electricity storage device 160 can store the generated electricity for a long time, so as to facilitate the subsequent use by end users at any time.
