Description

Technical Field

[0001] This utility model belongs to the field of renewable energy utilization technology, and in particular relates to a new energy cogeneration regional zero-carbon energy supply system. Background Technology

[0002] With the rapid development of clean and renewable energy grid connection, wind and solar energy, as environmentally friendly and renewable energy sources, have received widespread attention. In the operation and evaluation of wind and solar power systems, the power consumption ratio is a key indicator, reflecting the proportion of electricity generated by the system that is effectively utilized. A higher ratio indicates higher utilization efficiency and less energy waste. Because renewable energy generation from wind and solar power has strong randomness and volatility, direct grid connection without control will cause significant impact on the grid, affecting its safe and stable operation. It will also lead to a series of problems such as unbalanced grid absorption capacity and insufficient grid connection capacity.

[0003] Therefore, to increase the grid's capacity to absorb renewable energy, coal-fired power plants are currently widely used to provide peak shaving and frequency regulation services. However, the load factor of coal-fired power plants is limited by factors such as boiler evaporation, often making it difficult to fall below 30%. Furthermore, peak shaving by coal-fired power plants emits air pollutants, causing environmental problems. Traditional wind-solar hybrid power plants utilize the strong complementarity of solar and wind energy resources, to some extent compensating for the resource deficiencies of independent wind and solar power systems. However, they still cannot currently meet the needs of ensuring grid stability. Therefore, to increase the grid's capacity to absorb renewable energy, it is urgent to optimize the design of renewable energy power plants to reduce their impact on the grid. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-2 This utility model provides a new energy cogeneration regional zero-carbon energy supply system, including: wind and solar power 1, used to output electricity to the outside, part of the electricity of wind and solar power 1 is directly transmitted to the power grid, and the other part of the electricity of wind and solar power 1 is respectively transmitted to molten salt cogeneration system 2 and heat source station system 3.

[0031] The molten salt thermoelectric system 2 is coupled with the wind and solar power 1 and performs energy storage and peak regulation for the power grid. The molten salt thermoelectric system 2 includes a first loop with molten salt as the heat exchange medium. The first loop is also equipped with a heating and stirring mechanism 216 to prevent the first loop from being blocked.

[0032] The heat source station system 3 provides heat storage and heating to the heat load system 5 based on the electricity from the wind and solar power 1.

[0033] The heat exchange station system 4 is located between the heat source station system 3 and the heat load system 5.

[0034] Understandably, both the molten salt cogeneration system 2 and the heat source station system 3 are powered by wind and solar power 1. The wind and solar power 1 produces electricity and outputs it to the outside world. Part of the electricity output is stably transmitted directly to the municipal power system, and the other part is transmitted to the molten salt cogeneration system 2 and the heat source station system 3 respectively for consumption.

[0035] Among them, the molten salt thermal power system 2 is coupled with the wind and solar power system 1 and flexibly adjusts the production and consumption of electricity according to the power supply and demand situation.

[0036] Specifically, during periods of low electricity consumption, the wind and solar power system 1 produces excess electricity, and the molten salt cogeneration system 2 begins to absorb the excess electricity and stores it through energy conversion. During periods of high electricity consumption, the wind and solar power system 1 produces insufficient electricity, and the molten salt cogeneration system 2 converts the stored energy into electrical energy for external output, thus maintaining a relative balance between electricity production and consumption.

[0037] Understandably, heat exchange station system 4 transfers the heat energy from heat source station system 3 to heat load system 5 to complete heat exchange.

[0038] Understandably, in the molten salt thermoelectric system 2, the heat exchange medium in the first loop is molten salt. Energy storage and conversion are completed through the conversion between low-temperature molten salt and high-temperature molten salt. The heating and stirring mechanism 216 heats and disperses the blocky crystals or crystal particles generated in the low-temperature molten salt to prevent blockage in the first loop.

[0039] In a further optimized scheme, the first loop includes a molten salt heater 203, a high-temperature molten salt storage tank 204, a superheater 210, an evaporator 207, a preheater 208, and a low-temperature molten salt storage tank 206, which are sequentially closed-loop connected by pipelines. A first circulation pump 201 is provided between the high-temperature molten salt storage tank 204 and the superheater 210, and a second circulation pump 205 is provided between the low-temperature molten salt storage tank 206 and the molten salt heater 203. The first loop also includes a reheater 211, the input end of which is connected to the input end of the superheater 210, and the output end of which is connected to the output end of the superheater 210.

[0040] The molten salt thermoelectric system 2 also includes a steam turbine 215, a condenser 212, and a generator 214. The steam turbine 215 is equipped with a high-pressure cylinder and a medium-low-pressure cylinder. The preheater 208, evaporator 207, superheater 210, high-pressure cylinder, reheater 211, medium-low-pressure cylinder, and condenser 212 are sequentially closed-loop connected by pipes to form a second loop. A third circulation pump 209 is provided between the condenser 212 and the preheater 208. The output shaft of the steam turbine 215 is connected to the input shaft of the generator 214, and the power of the generator 214 is directly transmitted to the power grid.

[0041] Understandably, in the first circuit, the low-temperature molten salt storage tank 206 stores low-temperature molten salt, and the high-temperature molten salt storage tank 204 stores high-temperature molten salt. The low-temperature molten salt is heated to high-temperature molten salt by the molten salt heater 203, thereby storing electrical energy as thermal energy.

[0042] The first circulation pump 201 is used to extract the high-temperature molten salt from the high-temperature molten salt storage tank 204 and continuously send it into the pipeline, while the second circulation pump 205 is used to extract the low-temperature molten salt from the low-temperature molten salt storage tank 206 and continuously send it into the pipeline.

[0043] Understandably, the heat exchange medium in the second loop is water. The water medium exchanges heat with the high-temperature molten salt to form high-temperature and high-pressure steam. The steam expands in stages to drive the steam turbine 215 to do work, which in turn drives the generator 214 to generate electricity.

[0044] In a further optimized design, the heating and stirring mechanism 216 includes a central ring 2161 and a rotating ring 2163 coaxially arranged. A plurality of dispersing blades 2162 are uniformly fixed circumferentially between the central ring 2161 and the rotating ring 2163. A conical head 2164 is fixedly arranged on one side of the feed end of the central ring 2161. The rotating ring 2163 is rotatably installed in the first circuit between the second circulating pump 205 and the low-temperature molten salt storage tank 206. An induction heating coil 2166 is arranged on the outer side of the first circuit relative to the position of the rotating ring 2163.

[0045] Understandably, the rotating ring 2163 is installed between the second circulation pump 205 and the low-temperature molten salt storage tank 206, and is rotatably installed on the inner surface of the pipe. An induction heating coil 2166 is installed on the outer side of the pipe corresponding to the rotating ring 2163. When the induction heating coil 2166 is turned on, the temperature at the pipe corresponding to the rotating ring 2163 rises. When the low-temperature molten salt flows to the central ring 2161, it will be heated. When the low-temperature molten salt flows to the feed end side of the central ring 2161, the conical head 2164 will first come into contact with the low-temperature molten salt and cause the low-temperature molten salt to spread to the surroundings and flow to the dispersing blade 2162. The dispersing blade 2162 then starts to rotate, breaking up the blocky crystals or crystal particles generated in the low-temperature molten salt.

[0046] The central ring 2161 and the conical head 2164 both have hollow internal structures, which reduces the overall weight.

[0047] Understandably, the rotating ring 2163 can rotate freely inside the pipeline. When the second circulation pump 205 draws the low-temperature molten salt from the low-temperature molten salt storage tank 206 and sends it into the pipeline, the low-temperature molten salt flows forward rapidly under the action of the second circulation pump 205. When it flows towards the central ring 2161, the induction heating coil 2166 on the outside of the pipeline will heat the low-temperature molten salt. At the same time, several dispersing blades 2162 on the outside of the central ring 2161 will start to rotate spontaneously. The hardness of the blocky crystals or crystal particles in the low-temperature molten salt is greatly reduced after being heated, and then they are broken up by the rotating dispersing blades 2162, thereby preventing them from causing pipeline blockage.

[0048] In a further optimized scheme, the heat source station system 3 includes a hot water storage tank 301, which is equipped with a heater 302 and a first heat exchanger 303. The first heat exchanger 303 and the condenser 212 are interconnected by a pipeline to form a third loop. The third loop is connected to the second loop through the condenser 212. A fourth circulation pump 213 is also provided between the first heat exchanger 303 and the condenser 212.

[0049] Understandably, the steam in the second loop is still at a high temperature after doing work on the turbine 215. When the steam enters the condenser 212, some of the steam will enter the third loop under the action of the fourth circulation pump 213. When the steam flows into the first heat exchanger 303, it will exchange heat with the hot water in the hot water storage tank 301. The temperature of the hot water will rise, while the temperature of the steam will drop further.

[0050] Understandably, when the temperature of the hot water supplied in the hot water storage tank 301 does not meet the heating demand, the heater 302 is activated to heat the hot water supplied in the hot water storage tank 301.

[0051] In a further optimized scheme, the heat exchange station system 4 includes a hot water tank 402 and a second heat exchanger 404. One side of the hot water tank 402 is connected to the hot water storage tank 301 via a pipe, and the other side of the hot water tank 402 is connected to the second heat exchanger 404 via a pipe, forming a fourth loop with the hot water storage tank 301. A fifth circulation pump 401 is installed between the hot water tank 402 and the hot water storage tank 301, and a sixth circulation pump 403 is installed between the hot water tank 402 and the second heat exchanger 404.

[0052] In a further optimized scheme, the heat load system 5 includes several heat energy users 501. The input ends of the several heat energy users 501 are connected to the second heat exchanger 404, and the output ends of the several heat energy users 501 are connected to a circulating water pump 502. The circulating water pump 502 is connected to the second heat exchanger 404 and forms a fifth loop with the several heat energy users 501.

[0053] Understandably, the hot water supplied from the hot water storage tank 301 is drawn by the fifth circulation pump 401 and the sixth circulation pump 403 and transported to the second heat exchanger 404. The fifth loop is a circulating water circuit. The circulating water exchanges heat with the hot water supplied through the second heat exchanger 404 and supplies heat to several heat energy users 501 under the action of the circulating water pump 502.

[0054] In a further optimized scheme, the first circuit also includes several control valves 202. The inlet ends of the high-temperature molten salt storage tank 204 and the low-temperature molten salt storage tank 206 are both equipped with the control valves 202. The control valves 202 are also provided between the third circulation pump 209 and the condenser 212.

[0055] Understandably, when control valve 202 is open, the pipeline is open and its interior can pass through; when control valve 202 is closed, the pipeline is closed and its interior cannot pass through.

[0056] In a further optimized design, the feeding end of the dispersing blade 2162 is provided with an inclined first inclined surface 2165, and the number of the dispersing blades 2162 is 6.

[0057] Understandably, the dispersing blades 2162 have a certain tilt angle. When the low-temperature molten salt flows rapidly to the heating and stirring mechanism 216 under the action of the second circulation pump 205, several dispersing blades 2162 on the inner side of the rotating ring 2163 will spontaneously start to rotate and disperse the low-temperature molten salt. In particular, by opening an inclined first inclined surface 2165 on one side of the feed end of the dispersing blades 2162, the contact area between the low-temperature molten salt and its surface when it flows through the dispersing blades 2162 can be increased, the force of the low-temperature molten salt on the dispersing blades 2162 can be increased, and the rotating ring 2163 can be made easier to rotate and the rotation speed of the rotating ring 2163 can be increased.

[0058] Understandably, the angle between any two adjacent 2162 scattering blades is 60°.

[0059] In a further optimized design, both the high-temperature molten salt storage tank 204 and the low-temperature molten salt storage tank 206 have an insulation cotton layer on their outer surfaces.

[0060] Understandably, the insulation cotton layer is spirally wound around the outer surface of the high-temperature molten salt storage tank 204 and the low-temperature molten salt storage tank 206 to increase their insulation properties.

[0061] The working principle of this utility model is as follows:

[0062] The wind and solar power 1 generates electricity and transmits it to the municipal power system, while simultaneously providing heat to the heat source station system 3, which in turn supplies heat to the heat load system 5.

[0063] When electricity consumption is at a low point, the wind and solar power 1 supplies power to the molten salt cogeneration system 2. The second circulation pump 205 transports the low-temperature molten salt in the low-temperature molten salt storage tank 206 to the molten salt heater 203. The low-temperature molten salt gradually heats up to become high-temperature molten salt, and under the action of the first circulation pump 201, it is transported and stored in the high-temperature molten salt storage tank 204 through the control valve 202. The electrical energy is stored in the form of heat energy, making full use of and consuming the electricity generated by the wind and solar power 1.

[0064] During peak electricity consumption periods, all control valves 202 are opened. The high-temperature molten salt in the high-temperature molten salt storage tank 204 is then pumped to the superheater 210 and reheater 211 via the first circulation pump 201. When the high-temperature molten salt flows into the superheater 210, it exchanges heat with the flowing water to generate primary high-temperature, high-pressure steam. This primary high-temperature, high-pressure steam is directly delivered to the high-pressure cylinder of the turbine 215, driving the turbine to perform work and thus powering the generator 214. After driving the turbine's high-pressure cylinder, the temperature and pressure of the primary high-temperature, high-pressure steam gradually decrease, and it is then delivered to the reheater 211. In the reheater 211, it exchanges heat with the high-temperature molten salt, increasing its temperature and pressure to become secondary high-temperature, high-pressure steam. The steam is compressed and enters the low- and medium-pressure cylinder of the turbine 215, driving the turbine 215 to perform work and continue to drive the generator 214 to generate electricity. The secondary high-temperature and high-pressure steam enters the condenser 212 after driving the turbine 215 to perform work. Part of the steam enters the third loop through the fourth circulation pump 213 and is transported to the first heat exchanger 303. In the first heat exchanger 303, the steam exchanges heat with the hot water supply. After the steam exchanges heat, it flows back to the condenser 212. Under the action of the third circulation pump 209, it flows through the preheater 208, evaporator 207, superheater 210 and exchanges heat with high-temperature molten salt in sequence, gradually increasing in temperature and pressure to become primary high-temperature and high-pressure steam, which continues to drive the turbine 215 to drive the generator to generate electricity, and so on in a cycle to generate electricity.

[0065] The high-temperature molten salt flows through the reheater 210 and reheater 211, and then continues to flow through the evaporator 207 and preheater 208 in sequence. During this process, it exchanges heat with the medium water to become low-temperature molten salt, and then flows into the low-temperature molten salt storage tank 206 under the action of the second circulation pump 205, and so on in a continuous cycle.

[0066] In addition, the hot water in the hot water storage tank 301 exchanges heat with steam through the first heat exchanger 303, storing part of the heat from the steam in the hot water, raising the temperature of the hot water, and turning on the heater 302 until the hot water in the hot water storage tank 301 reaches the required heating temperature. The high-temperature water is then transported to the second heat exchanger 404 by the fifth circulation pump 401 and the sixth circulation pump 403. The circulating water exchanges heat with the hot water through the second heat exchanger 404 and is then supplied to several heat energy users 501 under the action of the circulating water pump 502. At the same time, the low-temperature water after heat exchange is returned to the hot water storage tank 301 under the action of the fifth circulation pump 401 and the sixth circulation pump 403 to continue heating. This heat storage and heating cycle is repeated.

[0067] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
