The electric energy is stored in the energy storage battery module 5 or is supplied to household loads 3 such as electric equipment of a refrigerator, an air conditioner and the like after being subjected to voltage reduction, voltage transformation and current stabilization. The cogeneration unit 300 is an existing process equipment complex capable of simultaneously producing electric energy and heat energy, and generates electricity by using fuel (such as clean energy sources of natural gas, coal gas, biogas and the like), and simultaneously recovers waste heat generated in the electricity generation process. In this design, in order to comprehensively utilize the waste heat energy generated by the cogeneration unit 300, i.e. high temperature flue gas, we design a set of flue gas heat energy exchanger 1 for recovering heat energy and storing the heat energy in the energy storage device 4. The energy storage device 4 comprises a tank body 41, a heat exchange water tank 42, an electric heating part 43, a plurality of heat bars 44 and a circulating pump 45, wherein the tank body 41 is internally filled with phase change energy storage materials, particularly molten salt, and the electric heating part 43 is inserted into the phase change energy storage materials. When the energy storage device 4 is required to store energy, the electric heating portion 43 is electrified to generate heat, and a specific electric energy source can be provided by the energy storage battery module 5 or the power grid. The phase-change energy storage material is heated and melted to store energy, the phase-change energy storage material stores large heat energy, and the phase-change energy storage can store more energy by using a smaller volume, so that the size of the tank 41 is reduced, the occupied area is reduced, and the phase-change energy storage material is suitable for personal families. and the heat storage time is long, the heat loss is small, and the heat energy utilization time can be greatly prolonged. In the design, the tank 41 and the heat exchange water tank 42 are made of heat insulation materials, so that heat loss is reduced. The phase-change energy storage material in the tank 41 is utilized to absorb heat, and the energy storage battery module 5 is matched to fully receive the garbage power generated by wind and light, so that the problem that the garbage power with large fluctuation directly gets on the internet to cause loss is avoided. Meanwhile, in order to efficiently utilize the heat energy stored in the tank 41, the heat energy is replaced by the heat exchange water tank 42 and the heat rod 44. The heat bar 44 is a hollow metal bar body, the inside is filled with phase change material, the evaporation section 441 of the heat bar 44 is inserted into the phase change energy storage material of the tank 41, and the condensation section 442 of the heat bar 44 is inserted into the heat exchange water tank 42 in an extending manner and is in contact with the liquid in the heat exchange water tank 42. The heat exchange water tank 42 is installed above the tank 41, and the plurality of heat bars 44 are vertically arranged, so that it is understood that when the temperature in the condensation section 442 of the heat bars 44 is lower than the temperature in the evaporation section 441 of the heat bars 44, the liquid phase change material in the heat bars 44 is heated, gasified and risen, and after the heat exchange between the condensation section 442 and the liquid in the heat exchange water tank 42, the liquid is cooled and re-liquefied, thereby realizing the design purpose of carrying heat energy from the tank 41 to the heat exchange water tank 42 through the heat bars 44. Specifically, the heat rod 44 is used as a high-efficiency heat conduction device, and has unique unidirectional heat conduction property, after absorbing the heat energy in the tank 41, the medium in the heat rod 44 rises to the condensation section 442 under the action of pressure difference to conduct the heat to the heat exchange water tank 42, and after cooling, the heat is naturally returned to the bottom evaporation section 441, and the heat rod 44 is used as a high-efficiency heat conduction device, so that the heat energy is automatically carried, and the energy is very saved. It is further understood that the liquid in the heat exchange water tank 42 may also absorb waste heat energy generated by the cogeneration unit 300 through the flue gas heat exchanger 1. The main pipeline 11 for introducing high-temperature flue gas is buried in the heat exchange water tank 42, the main pipeline 11 is a metal pipeline, and when the high-temperature flue gas passes through the heat exchange water tank 42, the high-temperature flue gas can exchange heat with liquid in the heat exchange water tank 42, so that the direct output of the high-temperature flue gas is avoided, and the heat energy is wasted. It will be appreciated that temperature sensors are provided in the main pipe 11, the heat exchange water tank 42 and the tank 41, and are electrically connected to the control terminal 6. If the temperature sensor in the main pipe 11 detects that the temperature of the passing flue gas is lower than the water temperature in the heat exchange water tank 42, in order to avoid reverse heat exchange, namely, the heat exchange water tank 42 transmits heat energy to the flue gas, we close the valve 12 on the main pipe 11, so that the flue gas is output through the bypass pipe 13, and the low-temperature flue gas does not pass through the heat exchange water tank 42, thereby preventing reverse heat energy transmission. And the temperature sensor in the tank 41 is used for detecting the temperature of the phase change energy storage material and controlling the power output of the electric heating part 43. Further, in order to prevent the smoke from polluting the atmosphere, a filtering device is arranged at the output port of the main pipeline 11 for filtering pollutants. In order to utilize the heat energy in the heat exchange water tank 42, the floor heating pipeline 2 is communicated with the heat exchange water tank 42, and when the circulating pump 45 is started, the hot water in the heat exchange water tank 42 can be pumped into the floor heating pipeline 2 buried in each room of the residence, so that a warm environment is provided for the room where the user lives. The design is extremely suitable for the living environment of northern Europe and the land, and the environment of remote areas in China, provides an all-round energy guarantee for users, and has extremely high energy storage and comprehensive utilization rate.
As shown in fig. 3-5, a necking section 443 is disposed between the evaporation section 441 and the condensation section 442 of the heat rod 44, an inner tube 444 is disposed in the heat rod 44, a gap is formed between the outer wall of the inner tube 444 and the inner wall of the heat rod 44, a plurality of spaced conical rings 445 are disposed on the outer side of the condensation section 442, the conical rings 445 are umbrella-shaped and hollow, and the upper end of the inner tube 444 is communicated with the conical rings 445 on the top end. Specifically, when the heat rod 44 is designed into three sections for heat conduction, the evaporation section 441 is inserted into the phase change energy storage material in the tank 41 and fully contacts with the phase change energy storage material, heat is absorbed, the phase change material in the heat rod 44 begins to evaporate into a gaseous state after being heated, the inner tube 444 is inserted into the heat rod 44, the cross section area of the inner tube 444 is larger than the circular ring area between the inner tube 444 and the inner wall of the heat rod 44, the evaporated airflow begins to float up under the action of the hot pressure difference in the initial state, and the airflow flow rate passing through the inner tube 444 is larger in unit time, so that most of the airflow is upwelled through the inner tube 444 and enters the condensation section 442, and in order to increase the heat exchange area of the condensation section 442 and the liquid in the heat exchange water tank 42, the tapered rings 445 are umbrella-shaped and hollow, and after the airflow enters the tapered rings 445 at the top end, the tapered rings 445 are spread out to perform large-area heat exchange with the low-temperature liquid in the heat exchange water tank 42, and the number of tapered rings 445 are stacked up and down, and the number of the tapered rings are three are mutually fully communicated, the heat exchange efficiency is greatly increased, and the heat exchange efficiency is fully increased, and the heat exchange efficiency is greatly increased from the inside the tapered rings and the heat exchange area is fully increased. When heat exchange is carried out, part of hot air flows are condensed into liquid, the liquid slides downwards under the action of gravity, the temperature of part of hot air flows is reduced, the hot air flows sink under the action of air pressure, and the subsequent hot air flows also extend above the inner tube 444 in the same direction, so that the hot air flows reciprocate, and the heat exchange is finished under the action of air pressure. The reduced temperature air flows back to the evaporator section 441 along the gap between the inner wall of the heat bar 44 and the inner tube 444, thereby forming a cycle. The air flow state of the whole heat exchange is laminar circulation exchange, the thermal resistance is relatively small, the air circulation is accelerated, and the heat exchange is more sufficient and rapid. Instead of the traditional convection exchange in the heat pipe, the heat resistance of the heat exchange is larger during convection, turbulent flow is easy to form in the heat rod, and airflow fluid molecules move randomly during turbulent flow, so that the heat resistance is increased.
As shown in fig. 5, the conical ring 445 is internally provided with a conical head 446, and the pointed cone of the conical head 446 is downward and faces the central axis of the inner tube 444. Specifically, the air flow floating up along the inner tube 444 flows out of the inner tube 444 to the topmost end, the gushed air flow is guided by the cone head 446 and spread out in all directions, the inner space of the cone ring 445 at the topmost layer is fully distributed, the heat exchange is carried out with the liquid in the heat exchange water tank 42, and the cone head 446 can rapidly increase the heat exchange area and improve the heat exchange efficiency.
Specifically, the heat bar 44 is liftable. Specifically, it can be understood that the photovoltaic storage generated by the solar power generation unit 100 only occurs in daytime, at this time, the temperature of each room in the house is suitable, and the floor heating pipeline 2 is not suitable to be opened for heating, in addition, when the energy storage battery module 5 is full of electricity, and the floor heating pipeline 2 is not required for heating, and only the tank 41 is required for energy storage under the two working conditions. At this time, in order to reduce the amount of heat energy stored in the tank 41 and dissipated into the heat exchange water tank 42 through the heat rod 44, the heat energy loss is reduced, and the heat rod needs to be pulled out of the phase change energy storage material in the tank 41, so that the contact area between the heat rod and the phase change energy storage material is reduced. The heat rod 44 is designed to be liftable, under the two working conditions, the heat rod 44 is driven to move upwards by a lifting device, such as a cylinder, an electric push rod or other screw rod structures, only the tail end of the heat rod 44 is left in the tank 41, the contact area between the heat rod 44 and the phase-change energy storage material is greatly reduced, the heat energy conduction efficiency is reduced, most of heat energy is ensured to be stored in the tank 41, and the heat energy cannot be automatically replaced into the heat exchange water tank 42 by the heat rod 44 and is wasted. After the floor heating pipeline 2 starts heating, the lifting device drives the hot rod to reset, the hot rod is reinserted into the tank 41, the contact area between the hot rod and the phase change energy storage material is increased, the heat conduction efficiency is improved, and the heating effect is ensured.
As shown in fig. 2, the tank body 41 includes an inner tank 411, an outer tank 412, a vacuum pump 413, a sealing cover 414 and a driving member 415, a gap exists between the inner tank 411 and the outer tank 412, the vacuum pump 413 is communicated with the gap, air in the gap is pumped away, the sealing cover 414 covers the outer tank 412 and seals the gap, a necking section 443 of the hot rod 44 is located in the sealing cover 414, and an output end of the driving member 415 is connected with the necking section 443 to drive the hot rod 44 to move up and down. Specifically, in this embodiment, the tank 41 is designed as a double-layer tank, and has good protection and service life enhancement due to the structural strength. The inner tank 411 and the outer tank 412 are sleeved with each other, a gap exists between the inner tank 411 and the outer tank 412, a heat insulation gasket is used for supporting and isolating the inner tank 411 and the outer tank 412, heat conduction of the inner tank 411 to the outer tank 412 is reduced, meanwhile, the inner tank 411 is supported, the vacuum pump 413 is used for vacuumizing the gap between the inner tank 411 and the outer tank 412, heat radiation of the inner tank 411 to the outer tank 412 is reduced, and loss amount of heat energy stored in the inner tank 411 is reduced.
