Description

Technical Field

[0002] Providing energy security for single-family homes in remote areas of my country and abroad is a thorny issue. In order to obtain sufficient energy and reduce energy costs, users currently use composite energy to provide sufficient energy for electrical appliances and heating equipment in their homes.

At present, the utilization of composite energy does not logically compare the generation and storage of solar energy, wind energy, and natural gas-biogas at the same time to select the best utilization and storage methods. The electricity generated by solar energy and wind energy is generally directly stored in household batteries, and the remaining is sold to the grid. After the large fluctuation of garbage power is connected to the grid, it will cause fluctuations in the voltage and frequency of the grid, affecting the stable operation of the grid, especially in remote areas of China and foreign countries where the grid infrastructure is poor.

[0027] like Figure 1~2As shown, a clean energy storage and regulation system includes a solar power generation unit 100, a wind power generation unit 200, a cogeneration unit 300, a flue gas heat exchanger 1, a floor heating pipe 2, a plurality of household loads 3, an energy storage device 4, an energy storage battery module 5 and a control terminal 6. The solar power generation unit 100, the wind power generation unit 200 and the cogeneration unit 300 are electrically connected to the household load 3, the energy storage battery module 5 and the power grid through the control terminal 6. The energy storage device 4 includes a tank body 41, a heat exchange water tank 42, an electric heating part 43, a plurality of heat rods 44 and a circulation pump 45. The interior of the tank body 41 is filled with a phase change energy storage material. The functional part of the electric heating part 43 is extended and arranged in the tank body 41 for heating the phase change energy storage material. The energy storage battery module 5 and the power grid respectively supply power to the electric heating part 43 and the circulation pump 45. The heat exchange water tank 42 is installed at the upper end of the tank body 41. The heat rod 44 is hollow. The interior is filled with phase change material, the evaporation section 441 of the heat rod 44 is inserted into the tank body 41, and the condensation section 442 of the heat rod 44 is inserted into the heat exchange water tank 42. The heat exchange water tank 42 is provided with a water inlet hole 421 and a water outlet hole 422. The water inlet hole 421 and the water outlet hole 422 are connected to both ends of the floor heating pipe 2. The circulating pump 45 is installed on the floor heating pipe 2 to drive the water flow to circulate in the floor heating pipe 2. The flue gas heat energy exchanger 1 includes a main Pipeline 11, valve 12 and bypass pipe 13, the main pipeline 11 is connected with the heat energy pipeline of the cogeneration unit 300, the main pipeline 11 runs through the water exchange tank 42, the bypass pipe 13 is arranged outside the water exchange tank 42, the two ends of the bypass pipe 13 are connected with the main pipeline 11, two sets of valves 12 are respectively arranged at the entrance of the main pipeline 11 and the bypass pipe 13, and the main pipeline 11, the water exchange tank 42 and the tank body 41 are all provided with temperature sensors. Specifically, in this embodiment, the electric energy generated by the solar power generation unit 100, the wind power generation unit 200 and the cogeneration unit 300 is distributed, stored and used through the control terminal 6, or directly connected to the power grid to sell electric energy. Specifically, the electric energy is stored in the energy storage battery module 5, or after step-down, transformation and current stabilization, it is supplied to the household load 3, such as refrigerators, air conditioners and other electrical equipment. Among them, the cogeneration unit 300 is an existing process equipment complex that can simultaneously produce electricity and heat energy. It uses fuel (such as natural gas, coal gas, biogas and other clean energy) to generate electricity and recovers waste heat generated during the power generation process. In this design, in order to comprehensively utilize the waste heat energy generated by the cogeneration unit 300, that is, high-temperature flue gas, we designed a flue gas heat exchanger 1 for recovering heat energy and storing it in the energy storage device 4. The energy storage device 4 includes a tank body 41, a water exchange water tank 42, an electric heating part 43, a number of heat rods 44 and a circulating pump 45. The inside of the tank body 41 is filled with phase change energy storage material, specifically molten salt, and the electric heating part 43 is inserted in the phase change energy storage material.When the energy storage device 4 needs to store energy, the electric heating part 43 is powered on to generate heat. The specific source of electric energy can be provided by the energy storage battery module 5 or the power grid. The phase change energy storage material is melted by heat to store energy. The phase change energy storage material has a large heat storage capacity, and the phase change energy storage can use a smaller volume to store more energy, thereby reducing the size of the tank body 41 and reducing the floor space, which is suitable for personal and household use. In addition, the heat storage time is long and the heat loss is small, which can greatly extend the utilization time of thermal energy. In this design, the tank body 41 and the heat exchanger tank 42 are both made of heat insulation materials to reduce heat loss. The phase change energy storage material in the tank body 41 is used to absorb heat, and the energy storage battery module 5 is used to fully receive the garbage electricity produced by wind and solar power, so as to avoid the garbage electricity with large fluctuations from being directly connected to the Internet and causing losses. At the same time, in order to efficiently utilize the thermal energy stored in the tank body 41, we use the heat exchanger tank 42 in conjunction with the heat rod 44 to replace the thermal energy for use. The heat rod 44 is a hollow metal rod filled with phase change material. The evaporation section 441 of the heat rod 44 is inserted into the phase change energy storage material of the tank 41, and the condensation section 442 of the heat rod 44 is extended and inserted into the heat exchange water tank 42 to contact the liquid in the heat exchange water tank 42. The heat exchange water tank 42 is installed above the tank 41, and a number of heat rods 44 are arranged vertically. It can be understood that when the internal temperature of the condensation section 442 of the heat rod 44 is lower than the temperature of the evaporation section 441 of the heat rod 44, the liquid phase change material inside the heat rod 44 is heated and vaporized and rises. After the condensation section 442 exchanges heat with the liquid in the heat exchange water tank 42, it is cooled and reliquefied, thereby achieving the design purpose of transporting heat energy from the tank 41 to the heat exchange water tank 42 through the heat rod 44. Specifically, the heat rod 44 does not need to be connected to provide kinetic energy output externally to carry heat energy. As a highly efficient heat conducting device, the heat rod 44 has a unique unidirectional heat conducting performance. After the medium inside absorbs the heat energy in the tank body 41, it rises to the condensation section 442 under the action of the pressure difference, and conducts the heat to the heat exchange water tank 42. After cooling, it naturally flows back to the evaporation section 441 at the bottom. This reciprocating cycle automatically carries heat energy, which is very energy-saving. It is further understandable that the liquid in the heat exchange water tank 42 can also absorb the waste heat energy generated by the cogeneration unit 300 through the flue gas heat energy exchanger 1. The specific design is to bury the main pipeline 11 for high-temperature flue gas in the heat exchange water tank 42. The main pipeline 11 is a metal pipeline. When passing through the heat exchange water tank 42, the high-temperature flue gas can exchange heat with the liquid in the heat exchange water tank 42, avoiding the direct output of high-temperature flue gas and wasting heat energy. It is understandable that temperature sensors are provided in the main pipeline 11, the heat exchange water tank 42 and the tank body 41, and the temperature sensor is electrically connected to the control terminal 6. If the temperature sensor in the main pipeline 11 detects that the temperature of the flue gas passing through is lower than the water temperature in the water exchange tank 42, in order to avoid reverse heat exchange, that is, the water exchange tank 42 transmits heat energy to the flue gas, we close the valve 12 on the main pipeline 11, so that the flue gas is output through the bypass pipe 13, and the low-temperature flue gas does not pass through the water exchange tank 42 to prevent reverse heat energy transmission.The temperature sensor in the tank 41 is used to detect the temperature of the phase change energy storage material and to regulate the power output of the electric heating unit 43. Furthermore, in order to prevent smoke from polluting the atmospheric environment, we set a filtering device at the output port of the main pipeline 11 to filter pollutants. In order to utilize the thermal energy in the water exchange tank 42, we connect the floor heating pipe 2 to the water exchange tank 42. When the circulating pump 45 is started, the hot water in the water exchange tank 42 can be pumped to the floor heating pipe 2 buried in each room of the house, providing a warm environment for the room where the user lives. This design is extremely suitable for the sparsely populated living environment in Northern Europe, as well as the environment in remote areas of my country, providing users with a comprehensive energy guarantee, and the energy storage and comprehensive utilization rate are extremely high.

[0028] like Figures 3-5As shown, a necking section 443 is provided between the evaporation section 441 and the condensation section 442 of the heat rod 44, an inner tube 444 is provided inside the heat rod 44, and there is a gap between the outer wall of the inner tube 444 and the inner wall of the heat rod 44, and a plurality of spaced conical rings 445 are provided on the outer side of the condensation section 442, and the conical rings 445 are umbrella-shaped and hollow, and the upper end of the inner tube 444 is connected to the conical ring 445 at the top. Specifically, we design the heat rod 44 into a three-stage type. When heat conduction is performed, the evaporation section 441 is inserted into the phase change energy storage material in the tank body 41, fully contacts with it, absorbs heat, and the phase change material in the heat rod 44 begins to evaporate into a gaseous state when heated. An inner tube 444 is inserted into the heat rod 44, and the cross-sectional area of ​​the inner tube 444 is larger than the area of ​​the annular ring between the inner tube 444 and the inner wall of the heat rod 44. In the initial state, the evaporated airflow begins to float up under the action of the thermal pressure difference. Since the airflow flow area of ​​the inner tube 444 is larger and the gas flow rate passing through per unit time is more, most of the hot airflow flows up through the inner tube 444 and enters the condensation section 442. In order to increase the condensation section In order to increase the heat exchange area between the condenser section 442 and the liquid in the heat exchange water tank 42, we set several conical rings 445 on the condensing section 442. The conical rings 445 are umbrella-shaped and hollow. After the hot air flow enters the conical ring 445 at the top, it spreads out and performs large-area heat exchange with the low-temperature liquid in the heat exchange water tank 42. Several conical rings 445 are stacked up and down. In this embodiment, there are three conical rings 445, which are interconnected so that the hot air flow inside them extends downward, and several conical rings 445 are filled with hot air flow from top to bottom in sequence, so as to fully contact with the low-temperature liquid outside, increase the heat exchange area, greatly improve the efficiency of heat exchange, and make heat exchange more sufficient. When performing heat exchange, part of the hot air flow condenses into liquid and slides down under the action of gravity, while part of the hot air flow temperature decreases and sinks under the action of air pressure. The subsequent hot air flow also extends above the inner tube 444, and so on. Under the action of air pressure, the heat exchange is completed. The airflow with reduced temperature returns to the evaporation section 441 along the gap between the inner wall of the heat rod 44 and the inner tube 444, thus forming a cycle. The airflow state of the entire heat exchange is a laminar circulation exchange, and the thermal resistance is relatively small, which accelerates the gas circulation and makes the heat exchange more sufficient and rapid. In contrast, in the non-traditional heat pipe convection exchange, the thermal resistance of the heat exchange is large during convection, and turbulence is easily formed in the heat rod. During turbulence, the airflow fluid molecules move in a disordered manner, increasing the thermal resistance.

[0029] like Figure 5As shown, a cone head 446 is provided at the inner top of the conical ring 445, and the pointed cone portion of the cone head 446 is provided downward and directly facing the central axis of the inner tube 444. Specifically, the airflow that floats up along the inner tube 444 flows out of the inner tube 444 at the top, and the gushing airflow is guided by the cone head 446 and spreads in all directions, filling the inner space of the topmost conical ring 445, and fully exchanging heat with the liquid in the water exchange tank 42. The cone head 446 can quickly increase the heat exchange area and improve the heat exchange efficiency.

[0030] Specifically, the heat rod 44 is liftable. Specifically, it is understandable that the photovoltaic storage generated by the solar power generation unit 100 will only occur during the day, when the temperature of each room in the house is suitable and it is not suitable to open the floor heating pipe 2 for heating. In addition, when the energy storage battery module 5 is fully charged and the floor heating pipe 2 is not needed for heating, the above two working conditions only require the tank body 41 to store energy. At this time, in order to reduce the amount of heat energy stored in the tank body 41 that is dissipated into the water exchange tank 42 through the heat rod 44 and reduce heat energy loss, it is necessary to pull the heat rod out of the phase change energy storage material in the tank body 41 to reduce the contact area between the heat rod and the phase change energy storage material. We design the heat rod 44 to be liftable. Under the above two working conditions, we use a lifting device, such as a cylinder, an electric push rod or other screw structure, to drive the heat rod 44 to move up, leaving only the end of the heat rod 44 in the tank body 41, which greatly reduces the contact area between the heat rod 44 and the phase change energy storage material, reduces the heat energy conduction efficiency, and ensures that most of the heat energy is stored in the tank body 41, and will not be automatically replaced by the heat rod 44 to the water exchange tank 42 and wasted. After the local heating pipe 2 starts heating, the lifting device drives the heat rod to reset and reinsert it into the tank body 41, increasing the contact area with the phase change energy storage material, improving the heat conduction efficiency, and ensuring the heating effect.

[0031] like Figure 2As shown, the tank body 41 includes an inner tank 411, an outer tank 412, a vacuum pump 413, a cover 414 and a driving member 415. There is a gap between the inner tank 411 and the outer tank 412. The vacuum pump 413 is connected to the gap to extract the air in the gap. The cover 414 covers the outer tank 412 and blocks the gap. The necking section 443 of the heat rod 44 is located in the cover 414. The output end of the driving member 415 is connected to the necking section 443 to drive the heat rod 44 to move up and down. Specifically, in this embodiment, the tank body 41 adopts a double-layer tank body design, which has a strong structure, good protection, and enhances its service life. The inner tank 411 and the outer tank 412 are set together, and there is a gap between them. A heat insulating gasket is used to support and isolate the inner tank 411 and the outer tank 412, thereby reducing the heat conduction from the inner tank 411 to the outer tank 412 and supporting the inner tank 411. The vacuum pump 413 is used to evacuate the gap between the inner tank 411 and the outer tank 412, thereby reducing the heat radiation from the inner tank 411 to the outer tank 412 and reducing the loss of heat energy stored in the inner tank 411. The cover 414 covers and seals the inner tank 411 and the gap, and supports the water exchange tank 42. A heat insulating coating is applied to the side of the cover 414 that is in contact with the inner tank 411 to reduce heat conduction. Most of the necking section 443 of the heat rod 44 is located in the cover 414, and the two ends of the necking section 443 extend into the inner tank 411 and the heat exchange water tank 42. The two ends of the necking section 443 pass through the bottom of the cover 414 and the bottom of the heat exchange water tank 42 through the sealing ring. The sealing ring is a metal ring, and a number of high-temperature resistant rubber rings are set on the inner ring. When the necking section 443 and the sealing ring are relatively displaced, gas and liquid can be prevented from leaking out. The necking section 443 is connected to the output end of the driving member 415. Specifically, the driving member 415 can adopt a screw structure to drive the necking section 443 to move up and down as a whole, thereby driving the heat rod 44 to rise and fall. In other embodiments, the driving member 415 can also directly use an electric push rod.

[0032] Specifically, a spiral pattern is provided on the inner wall of the inner tube 444 , and the spiral pattern serves to guide the airflow generated when the phase change material in the heat rod 44 evaporates.

[0033] like Figure 2As shown, a ceramic joint 111 is provided at the connection between the main pipe 11 and the wall of the heat exchange water tank 42, and the pipe body of the main pipe 11 located in the heat exchange water tank 42 is spiral. Specifically, the main pipe 11 adopts a metal pipe. When the high-temperature flue gas generated by the cogeneration unit 300 flows in the main pipe 11, the heat exchange with the liquid in the heat exchange water tank 42 is sufficient to ensure the heat exchange efficiency. We design the part of the main pipe 11 located in the heat exchange water tank 42 to be spiral. When the high-temperature flue gas flows in the spiral pipe, the gas flow rate is reduced to ensure sufficient heat exchange with the liquid. At the same time, the length of the main pipe 11 in the heat exchange water tank 42 is extended to increase the heat exchange area. The ceramic joint 111 is sleeved on the pipe where the main pipe 11 contacts the wall of the heat exchange water tank 42 to prevent the heat exchange water tank 42 from directly contacting the pipe body of the main pipe 11, causing the main pipe 11 made of metal to transfer heat energy to the wall of the heat exchange water tank 42, resulting in a reduction in the heat energy transferred to the liquid in the heat exchange water tank 42.

[0034] like Figure 2 As shown, the energy storage device 4 also includes an external water system 46, which includes an external water pipe 461, a water inlet valve 462 and a water outlet valve 463. The pipeline of the external water pipe 461 runs through the heat exchange water tank 42, and the water inlet valve 462 and the water outlet valve 463 are respectively arranged on the pipeline of the external water pipe 461 entering and exiting the heat exchange water tank 42. Specifically, when the local heating pipe 2 is not opened, and the cogeneration unit 300 is working, the high-temperature flue gas generated passes through the flue gas heat energy exchanger 1, and transmits heat energy to the liquid in the heat exchange water tank 42. At this time, the water flow flowing in the external water system 46 is used to drain the heat energy out. It can be understood that the part of the external water pipe 461 buried in the heat exchange water tank 42 is a metal pipe. The user opens the inlet valves at both ends of the external water pipe 461 entering and exiting the heat exchange water tank 42, and tap water enters the heat exchange water tank 42 through the external water pipe 461, and heat exchange can be carried out to output hot water, which is convenient for users to wash in winter. There is no need to turn on the fire to boil water in winter, and the user experience is excellent.

[0035] A scheduling method for a clean energy storage regulation system comprises the following steps:

[0036] S1, the control terminal 6 is used to manage and distribute the generated electric energy of the solar power generation unit 100, the wind power generation unit 200 and the cogeneration unit 300, and distribute the generated electric energy to the energy storage battery module 5 and the energy storage device 4 for storage, or supply it to the DC household load 3, or sell it to the power grid. The cogeneration unit 300 stores the waste heat energy generated by power generation in the heat exchanger tank 42 of the energy storage device 4 through the flue gas heat exchanger 1. Specifically, the control terminal 6 controls the distribution of the generated electric energy of the solar power generation unit 100, the wind power generation unit 200 and the cogeneration unit 300, specifically, the electric energy is stored through the energy storage battery module 5, and the household load 3 uses the electric energy. When the energy storage battery module 5 is fully charged, the energy storage battery module 5 and the cogeneration unit 300 respectively transmit the electric energy and the waste heat energy to the energy storage device 4 for storage, thereby improving energy utilization and reducing losses.

[0037] S2, the control terminal 6 starts the circulation pump 45 in the energy storage device 4, and cooperates with the floor heating pipe 2 to heat several rooms of the residence. Specifically, the control terminal 6 opens the valve in the floor heating pipe and starts the circulation pump 45, so that the heat exchange water tank 42 automatically replaces the heat from the tank body 41 through the heat rod 44, the internal water temperature rises, and the circulation pump 45 pumps the hot water to each room, so that the room can be heated.

[0038] S3, the control terminal 6 detects condition parameters of several rooms through a detection device, and adjusts the output power of the electric heating part 43 of the energy storage device 4 according to the condition parameters.

[0039] Specifically, in step S3, the detection device first detects whether there is someone in the current room through an infrared detection head. If not, the control terminal 6 closes the valve in the floor heating pipe 2 in the current room. If yes, the detection device detects the temperature and humidity of the current room through a temperature sensor and a humidity sensor, and adjusts the output power of the electric heating part 43 of the energy storage device 4 according to the temperature and humidity information.

[0040] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
