[0003] However, existing thermal power plants generally use gas-fired boilers. Although gas-fired boilers have advantages such as high efficiency and cleanliness, there are also some problems and challenges in actual use. These include a significant decrease in the efficiency of gas-fired boilers when operating under load, resulting in unstable heat and low thermal efficiency. In addition, there are also problems such as emission pollution. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1:

[0024] Reference Figure 1-5A multi-energy integrated thermal power station includes a base plate 1, on which a hot water storage tank 2, a water supply component 3, a power distribution box 4, and a monitor 5 are installed. The hot water storage tank 2 has a double-layer structure, including an outer casing 20 and an inner casing 21. An insulation layer 22 is also provided between the outer casing 20 and the inner casing 21. The hot water storage tank 2 can not only store the heat pump energy heated by the water supply component 3, but also replenish the lost heat through gas energy, ensuring that the heat source is always maintained within a stable temperature range. The water supply components 3 consist of multiple sets. Taking water as the heat source, each set of water supply components 3 can divert the cold water from the main pipe 6, thus forming multiple sets to supply cold water separately. Each set of water supply components 3 also includes a cold water supply component 30 and a hot water supply component 31. The input end of the cold water supply component 30 is connected to an external water pump through the main pipe 6. The cold water supply component 30 is connected to the hot water supply component 31, and the hot water supply component 31 is connected to the inner tank 21. The main purpose of the cold water supply component 30 is to ensure... The cold water pressure is stable, and the cold water can be treated before being heated by the hot water supply component 31. After further treatment, it is finally stored inside the hot water storage tank 2. An air inlet pipe 7 and an air outlet pipe 8 are also provided on one side of the outer casing 20. These pipes can be connected to external heating equipment, forming a stable circulation loop to maintain a stable temperature inside the hot water storage tank 2. The power distribution box 4 and the monitor 5 are mounted on the base plate 1 via the first bracket 9 and the second bracket 10, respectively. The power distribution box 4 mainly provides power to the monitor 3 and various electronic devices.

[0025] The insulation layer 22 between the outer casing 20 and the inner casing 21 is made of polyurethane foam. The outer casing 21 is also wrapped with a heating coil 11. A water temperature sensor 12 and a pressure sensor 13 are also installed inside the inner casing 21. When the heat pump 311 cannot meet the demand (such as in extremely cold weather), the heating coil 11 can be used to heat the heat source inside the inner casing 21 or make up for the loss. The water temperature sensor 12 is used to monitor the water temperature, while the pressure sensor 13 mainly monitors the internal pressure change. When the pressure changes, the pressure relief valve 17 can be used to release the pressure to prevent the internal pressure from becoming too high. The water temperature sensor 12 and the pressure sensor 13 are respectively connected to the monitor 5 for signal transmission.

[0026] The outer casing 20 is also equipped with a liquid level pipe 14, both ends of which are connected to the inner casing 21. The main purpose of the liquid level pipe 14 is to know the liquid level inside the inner casing 21 for easy observation. The bottom of the outer casing 20 is also equipped with a water outlet valve 15, which can draw out the heat source inside the inner casing 21 and then directly transmit it to the user end through the pipeline. The air inlet pipe 7 and the air outlet pipe 8 are respectively connected to the two ends of the heating coil 11. The air inlet pipe 7 and the air outlet pipe 8 can introduce external boilers or other heat sources, which can assist in heating and maintain heat when the heat pump 311 is not working or cannot meet the demand.

[0027] The top of the outer casing 20 is also provided with a removable cover 16 and a pressure relief valve 17. The removable cover 16 is located in the middle of the outer casing 20. The inner wall of the inner casing 21 can be cleaned regularly through the removable cover 16 to prevent impurities from entering. Corner plates 18 are also fixedly installed at the four corners of the outer casing 20. The corner plates 18 can facilitate the movement of the hot water storage tank 2.

[0028] The substrate 1 has a frame structure, and migration plates 19 are installed on both sides of the substrate 1. The migration plates 19 have round holes. The frame structure of the substrate 1 not only saves material, but also makes it easy to move and transport.

[0029] Water meter 23 and pressure gauge 24 are also installed sequentially on the main pipeline 6. Water meter 23 and pressure gauge 24 can be used to understand the working conditions and real-time data information of the entire energy station.

[0030] The cold water supply assembly 30 includes a first branch pipe 301, a water supply valve 302, a check valve 303, a water quality monitor 304, and a pressure reducing valve 305. The output end of the first branch pipe 301 is connected to the output end of the main pipe 6. The water supply valve 302, check valve 303, water quality monitor 304, and pressure reducing valve 305 are installed sequentially on the first branch pipe 301. The water supply valve 302 mainly supplies water through an external water pipe when the water pressure is unstable. The check valve 303 mainly prevents cold water backflow. The water quality monitor mainly monitors the pH value, conductivity, dissolved oxygen content, etc. of the cold water to ensure the safety of hot water or meet specific process requirements. The output end of the first branch pipe 301 is also connected to the hot water supply assembly 31.

[0031] The hot water supply assembly 31 includes a second branch pipe 310, a heat pump 311, an exhaust valve 312, and an ultraviolet sterilizer 313. The input end of the second branch pipe 310 is connected to the output end of the first branch pipe 301, and the output end of the second branch pipe 310 is connected to the inner casing 21. The heat pump 311, the exhaust valve 312, and the ultraviolet sterilizer 313 are also installed sequentially on the second branch pipe 310. The heat pump 311 is fixedly installed on the base plate 1. The heat pump 311 can convert a low-level heat source into a high-level heat source. The exhaust valve 312 can reduce the air pressure in the second branch pipe 310, ensuring that the second branch pipe 310 can continuously deliver a stable heat source. The ultraviolet sterilizer 313 mainly plays a sterilization role.

[0032] Working principle:

[0033] When the main pipe 6 is pumped by an external water pump, the cold water flows through the water meter 23 and pressure gauge 24, and then is diverted into different first branch pipes 301. The cold water in the first branch pipe 301 enters the water quality monitor 304 for monitoring to prevent unqualified cold water from directly entering the heat pump 311. Then, it flows into the heat pump 311 through the second branch pipe 310. The heat pump 311 can circulate low-grade heat energy into high-grade heat energy through an electrically driven compressor to heat the heat source. After heating, the heat source is disinfected by an ultraviolet sterilizer 313 and then transported to the inner chamber 21 for storage. The inner chamber 21 not only ensures the stability of the heat, but also replenishes the heat loss in time or can replace the heat pump 311 in time when it cannot work, ensuring the stability of the entire output heat source.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
