Description

[0001] This invention relates to the field of solid thermal storage, and more particularly to a solid thermal storage steam device. Background Technology

[0002] Solid thermal storage steam systems mainly refer to applications that use electricity generated from off-peak electricity or green energy sources to store thermal energy in solid thermal storage bodies. When in use, heat exchange technology is used to release the thermal energy in the solid thermal storage bodies in the form of steam.

[0003] However, since steam generation primarily relies on the supersaturated section's thermal energy, and the condensed section's thermal energy, formed after heat exchange, flows back to the solid thermal storage body through the heat exchange medium, this portion of thermal energy needs to be reheated by the solid thermal storage body and the heat exchange process repeated before it can function again in the steam generator. This results in low heat exchange efficiency and energy waste in traditional solid thermal storage steam devices. Therefore, there is an urgent need for a solid thermal storage steam device to solve the aforementioned problems. Summary of the Invention

[0042] like Figures 1-7 As shown, a solid thermal storage steam device includes:

[0043] A heat storage box 1 has a solid heat storage chamber inside, in which a solid heat storage body 2 is installed. A fan 3 is connected to one side of the solid heat storage chamber. A heat release chamber is located inside the heat storage box 1, on the side of the solid heat storage chamber away from the fan 3. The heat release termination end of the heat release chamber is connected to the air inlet end of the fan 3. The temperature in the heat release chamber gradually decreases along the direction closer to the fan 3. A first heat exchange unit is located at the heat release initiation end of the heat release chamber. A second heat exchange unit is located inside the heat release chamber on the side close to the first heat exchange unit. A steam box 4 is located on one side of the heat storage box 1. An evaporation chamber 5 is defined inside the steam box 4. A steam outlet 29 is opened at the top of the evaporation chamber 5. The first heat exchange unit acts on the evaporation chamber 5 to release heat. A water storage tank 6 is fixed inside the steam box 4. A water supply pipe 7 is connected to one side of the water storage tank 6. The water outlet end of the water storage tank 6 is connected to the evaporation chamber 5. The second heat exchange unit acts on the water storage tank 6 to release heat.

[0044] This invention utilizes a solid heat storage body 2 installed within a heat storage tank 1 to convert off-peak electricity and green energy into thermal energy for storage. A heat release chamber is defined within the heat storage tank 1, positioned on the side of the solid heat storage chamber opposite the fan 3. The fan 3 blows air into the heat release chamber, and the temperature inside the heat release chamber gradually decreases towards the fan 3, thus forming a circulating air duct. A first heat exchange unit and a second heat exchange unit are sequentially distributed, with the first heat exchange unit attached to the heat release initiation end of the heat release chamber. The first heat exchange unit absorbs supersaturated heat and applies it to the steam tank 4 for steam release. After some heat is absorbed, the second heat exchange unit can recover secondary heat and transfer it to the water storage tank 6 for preheating the water to be evaporated. This not only increases the steam release rate but also effectively utilizes secondary heat, significantly improving energy efficiency.

[0045] Specifically, traditional heat storage steam devices typically directly feed external water into the evaporator. In cold regions, where the normal water temperature is low, the heat exchanged directly evaporates the low-temperature water, resulting in a large amount of heat consumption and a high heat requirement. In contrast, this application utilizes the first and second heat exchange units to fully absorb heat and pre-treats the low-temperature water using a gradient heating method. Then, it uses supersaturated heat to evaporate the treated warm water, effectively improving the overall heat exchange-evaporation efficiency of the device.

[0046] Furthermore, it also includes:

[0047] The first heat-releasing pipe 8 is connected and fixed to the side of the solid heat storage chamber away from the fan 3. Several first heat-releasing pipes 8 are provided, and the several first heat-releasing pipes 8 are distributed in a matrix along the vertical direction. The first heat exchange unit is attached to the first heat-releasing pipe 8.

[0048] The second heat-dissipating pipe 9 is located below the lowest first heat-dissipating pipe 8. Several first heat-dissipating pipes 8 and the second heat-dissipating pipe 9 are connected by a connecting pipe 10. The side of the second heat-dissipating pipe 9 facing the fan 3 is connected to an outlet pipe 11. The second heat exchange unit is attached to the outlet pipe 11.

[0049] By fixing the first heat release pipe 8 and the second heat release pipe 9 in the heat storage box 1, the heat release pipe 8 absorbs higher heat and the second heat release pipe 9 recovers the remaining heat in the direction of decreasing temperature in the heat release chamber. The heat is systematically graded so that the supersaturated heat can be fully applied to the evaporation chamber 5 to release steam, while the lower temperature heat energy is used to heat up the low temperature water in the water storage tank 6.

[0050] A number of first heat-exchanging pipes 8 and second heat-exchanging pipes 9 are connected by a connecting pipe 10, and the heat exchange gas in the second heat-exchanging pipe 9 is finally released through the outlet pipe 11, so that the heat decreases step by step and is exchanged and utilized through the first heat exchange unit and the second heat exchange unit.

[0051] Furthermore, the first heat exchange unit includes:

[0052] The heat exchange network 12 is set inside the heat release chamber and is formed by connecting and fixing several heat exchange pipes. The heat exchange network 12 is attached to several first heat release pipes 8. The two sides of the heat exchange network are respectively connected to the first water inlet pipe 13 and the first water outlet pipe 14.

[0053] The heat-dissipating plate 15 is fixed inside the heat storage box 1. The heat-dissipating plate 15 is attached to the evaporation chamber 5. The opposite sides of the heat-dissipating plate 15 are respectively connected to the first water inlet pipe 13 and the first water outlet pipe 14.

[0054] The heat exchange network 12, which is arranged in a mesh structure, is used to exchange and absorb heat with a number of first heat-dissipating tubes 8 arranged in an array, so as to maximize the contact area and improve the heat exchange efficiency. Water is circulated in the heat exchange network 12 through the first water inlet pipe 13 and the first water outlet pipe 14 to maintain the heat transfer effect of the heat exchange medium.

[0055] Heat is transferred to the heat-dissipating plate 15 through the first water outlet pipe 14. The heat-dissipating plate 15 is attached to the evaporation chamber 5, thereby heating the evaporation chamber 5 and releasing steam.

[0056] Furthermore, a first control valve 16 is provided on both the first water inlet pipe 13 and the first water outlet pipe 14; the first water outlet pipe 14 is connected to the starting end of a capillary tube 17 on the side near the heat dissipation plate 15, the capillary tube 17 is configured to extend into the heat dissipation plate 15 in a coiled manner, and the terminating end of the capillary tube 17 extends out of the heat dissipation plate 15 and is connected to the first water inlet pipe 13 through a pipe 18.

[0057] Heat is fully transferred to the heat-dissipating plate 15 through a coil-shaped capillary tube 17 (the structure is not shown in the figure and is a conventional technology), and the water circulation in the heat exchange system is controlled by the first control valve 16 to regulate the release of steam and the absorption and utilization of heat from the solid heat storage body 2.

[0058] Furthermore, the second heat exchange unit includes:

[0059] Heat exchanger 19 is fixed to the bottom of the heat storage box 1. Heat exchanger 19 is in contact with outlet pipe 11. A cavity is opened in heat exchanger 19. The second water inlet pipe 20 and the second water outlet pipe 21 are respectively connected to the opposite sides of the cavity.

[0060] The heat pipe 22 is fixed inside the steam box 4. A channel is opened in the middle of the water storage tank 6. The heat pipe 22 passes through the channel. The two ends of the heat pipe 22 are connected to the second water inlet pipe 20 and the second water outlet pipe 21 respectively. A second control valve 23 is provided on both the second water inlet pipe 20 and the second water outlet pipe 21.

[0061] The heat exchange medium is stored in the cavity opened in the heat exchanger 19 and circulated and released through the second inlet pipe 20 and the second outlet pipe 21. The heat released by the outlet pipe 11 is absorbed and transferred to the heat conduction pipe 22. By inserting the heat conduction pipe 22 in the middle of the water storage tank 6, the heat pretreatment of the inside of the water storage tank 6 is realized. At the same time, the second control valve 23 is used to regulate the temperature rise of the water storage tank 6.

[0062] Specifically, a water supply pipe (not shown in the figure) can be selectively connected to the first water inlet pipe 13 and the second water inlet pipe 20, and an on / off valve is provided on the water supply pipe for replenishing the heat exchange medium.

[0063] Furthermore, a first heat insulation plate 24 is fixedly connected to the bottom of the heat storage box 1, and a second heat insulation plate 25 is fixedly connected to the top surface of the first heat insulation plate 24 away from the fan 3. The top of the second heat insulation plate 25 is fixedly connected to the top surface of the heat storage box 1. The first heat insulation plate 24 and the second heat insulation plate 25 cooperate to define the solid heat storage cavity.

[0064] A solid heat storage cavity is enclosed inside the heat storage box 1 by the first heat insulation plate 24 and the second heat insulation plate 25, and the solid heat storage body 2 is placed on the first heat insulation plate 24 to achieve heat preservation and isolation of the solid heat storage body 2.

[0065] Specifically, the second heat insulation plate 25 is the side wall of the solid heat storage chamber away from the fan 3. Several first heat release pipes 8 are connected and fixed on the second heat insulation plate 25. The first heat release pipes 8 are bent pipes. Both ends of the first heat release pipes 8 are connected to the interior of the solid heat storage chamber. Hot air is sent from the first heat release pipes 8 to the second heat release pipes 9 through the connecting pipe 10.

[0066] Furthermore, a first gap is provided between the first heat insulation plate 24 and the inner bottom surface of the heat storage box 1, and a second gap is provided between the inner wall surface of the heat storage box 1 opposite to the fan 3 and the second heat insulation plate 25. The first gap and the second gap are connected, and the two cooperate to define the heat release cavity.

[0067] By defining the first and second gaps within the heat storage tank 1, a circulating air duct for the heat release chamber is formed. The heat release initiation end of the heat release chamber is attached to the second heat insulation plate 25. High-temperature heat is absorbed from the heat exchanger and transferred to the steam chamber for steam production, while low-temperature heat is released towards the fan 3 through the second heat release pipe 9 and the outlet pipe 11. The fan 3 then re-introduces the gas into the solid heat storage chamber for repeated heating. During this process, the heat exchanger 19 can perform secondary recovery of this portion of heat and apply it to the water storage tank 6 to pre-treat the low-temperature water.

[0068] Furthermore, the diameter of the heat exchange tube is smaller than the diameter of the first heat release tube 8, and the diameter of the connecting tube 10 does not exceed the diameter of the first heat release tube 8.

[0069] In one embodiment of this technical solution, the diameter of the first heat-releasing pipe 8 is larger than that of the heat exchange pipe. When distributing the heat exchange pipe, the heat exchange pipe is arranged horizontally at the joint between the connecting pipe 10 and the first heat-releasing pipe 8. Due to the diameter difference between the first heat-releasing pipe 8 and the connecting pipe 10, the heat exchange gas will form a hot air agglomeration when it flows into the connecting pipe 10, which will fully enhance the heat in this part. By directly arranging the heat exchange pipe here, the heat absorption efficiency of the entire heat exchange system for the first heat-releasing pipe 8 can be fully improved, thereby achieving the purpose of accelerating the heat exchange efficiency.

[0070] Furthermore, the evaporation chamber 5 is enclosed by a heat-conducting material, and fins 26 are fixed to opposite sides of the inner wall of the evaporation chamber 5. A gap is provided between the two fins 26 that are distributed opposite to each other, and several fins 26 located on the same side are distributed at equal intervals in the vertical direction.

[0071] Common thermally conductive materials such as copper, aluminum, and stainless steel are used. Heat is transferred to the evaporation chamber 5 through the heat dissipation plate 15, and the heat is fully released through the fins 26. The spaced distribution of the fins 26 accelerates the heating efficiency of the water, increases the heating contact area, and effectively promotes the release of steam.

[0072] Furthermore, a water pump 27 is fixedly connected to the top surface of the water storage tank 6, and the outlet end of the water pump 27 is connected to the evaporation chamber 5 through a water delivery pipe 28.

[0073] Specifically, a level gauge can be connected to the outside of the evaporation chamber 5, which, together with the water supply pump 27, can effectively control the water supply and prevent excessive water from overflowing from the steam outlet 29. This is a conventional design structure and will not be described in detail.

[0074] This invention provides a working principle for a solid thermal storage steam device:

[0075] By feeding low-temperature water into the water storage tank 6 through the water supply pipe 7 and starting the fan 3, the heat stored in the solid heat storage body 2 is transferred to the first heat release pipe 8. The heat exchange network 12, which is arranged in a mesh structure, performs heat exchange absorption on the array of first heat release pipes 8. The heat is transferred to the heat release plate 15 through the first water outlet pipe 14. The heat release plate 15 is attached to the evaporation chamber 5 and the heat is fully applied to the heat release plate 15 through the capillary tube 17. The remaining heat is transferred to the second heat release pipe 9 and released from the outlet pipe 11 toward the fan 3. The heat exchange medium is stored in the cavity opened in the heat exchanger 19 and circulated through the second water inlet pipe 20 and the second water outlet pipe 21. The heat released from the outlet pipe 11 is absorbed and transferred to the heat conduction pipe 22, thereby pre-treating the low-temperature water in the water storage tank 6 to improve the heat exchange steam release efficiency.
