Abstract

This invention discloses a molten salt electrode boiler with energy storage function, relating to the technical field of molten salt electrode boilers. It solves the technical problem of heat loss due to the lack of corresponding preheating measures, resulting in uneven temperature distribution between the high-temperature molten salt that first falls to the bottom of the containment cavity and the high-temperature molten salt falling subsequently into the containment cavity. The boiler includes a boiler body with a distribution pipe for conveying low-temperature molten salt inside, and nozzles on the upper side of the distribution pipe. This invention utilizes the low-temperature molten salt sprayed onto a rotating blade assembly in a conversion component. The kinetic potential energy drives the central shaft to rotate, cutting magnetic field lines to generate electrical energy, which is stored. This stored electrical energy is then used to preheat the bottom of the boiler body, reducing heat loss from the high-temperature molten salt falling to the bottom of the boiler body and maintaining the high-temperature molten salt within a suitable temperature range.

Description

Technical Field

[0001] This invention belongs to the technical field of molten salt electrode boilers, specifically a molten salt electrode boiler with energy storage function. Background Technology

[0002] Molten salt electrode boilers are a type of electrode boiler. Electrode boilers use alternating current to heat molten salt, which acts as a heating resistor to heat the medium (such as water or steam).

[0003] For example, an electrode boiler for heating molten salt, with announcement number CN111306789B, includes: a shell forming a receiving cavity; a low-temperature molten salt distribution header extending vertically into the receiving cavity and capable of spraying molten salt in at least one direction; and an electrode heating unit including an electrode plate capable of being electrically connected, the electrode plate being arranged in the receiving cavity along a direction substantially parallel to the low-temperature molten salt distribution header, the electrode plate being capable of connecting and heating molten salt when molten salt is sprayed onto it, and being capable of disconnecting the connection and stopping heating when no molten salt is sprayed onto it.

[0004] In the aforementioned patent, the low-temperature molten salt falls to the bottom of the containment cavity after being heated, but there is a lack of corresponding preheating measures. This results in a relatively lower temperature for the high-temperature molten salt that falls to the bottom of the containment cavity first, causing an overall decrease in the temperature of the high-temperature molten salt and an uneven temperature distribution with the high-temperature molten salt that falls into the containment cavity later.

Detailed Implementation

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1 - Figure 6 This application provides a molten salt electrode boiler with energy storage function, comprising:

[0047] The boiler body 100 has a distribution pipe 101 for conveying low-temperature molten salt inside. The upper side of the distribution pipe 101 is equipped with nozzles. The number of nozzles can be set according to actual needs. Low-temperature molten salt is supplied to the distribution pipe 101 from the outside, and the low-temperature molten salt is sprayed out from multiple nozzles.

[0048] An energy storage and conversion structure 200, installed outside the nozzle, utilizes the kinetic potential energy of the low-temperature molten salt spray to convert and store energy. Using this structure 200, the low-temperature molten salt spray acts on the conversion component 202, using the kinetic potential energy to drive the central shaft 2025 to rotate, cutting magnetic field lines and generating electrical energy. This electrical energy is stored and used to power the preheating component 300, allowing it to preheat the bottom of the boiler body 100, reducing heat loss from the high-temperature molten salt falling onto the bottom of the boiler body 100 and maintaining a high temperature. Molten salt is used within a suitable temperature range. The energy storage conversion structure 200 includes a conversion component 202 sleeved on the nozzle, an energy storage box 201 installed on the outer surface of the boiler body 100 for energy storage, and a wiring conduit 203 installed between the conversion component 202 and the energy storage box 201. The energy storage box 201 is equipped with an energy storage battery. The wiring conduit 203 is made of high-temperature resistant ceramic fiber tubes. The wiring conduit 203 is equipped with a cable connecting the winding 2023 and the energy storage box 201. The wiring conduit 203 is used to protect and insulate the cable.

[0049] And a preheating component 300 installed at the lower end of the boiler body 100 for preheating.

[0050] In this embodiment, preferably, the conversion component 202 utilizing the kinetic potential energy conversion of low-temperature molten salt includes:

[0051] The heat-resistant outer shell 2021 is fixedly sleeved on the nozzle. Both the heat-resistant outer shell 2021 and the heat-resistant inner shell 2022 are made of high-temperature resistant zirconia shells, which have the function of high-temperature protection. A rotating blade assembly 2028 is set inside the left end of the heat-resistant outer shell 2021 near the nozzle. The structure of the nozzle can be set according to actual production needs, and it can be a high-pressure nozzle. The force sprayed out meets the potential energy required for the rotation of the rotating blade assembly 2028.

[0052] The heat-resistant inner shell 2022 is located inside the heat-resistant outer shell 2021, and multiple reinforcing brackets are provided between the two. This does not affect the flow of low-temperature molten salt, and can also fix the heat-resistant inner shell 2022. A reinforcing seat 2029 is provided between two adjacent heat-resistant outer shells 2021. A winding 2023 is provided on the inner surface of the heat-resistant inner shell 2022.

[0053] The central shaft 2025 installed at the center of the heat-resistant inner shell 2022 can rotate as the rotating blade assembly 2028 rotates, thereby driving the permanent magnet 2024 to rotate. The permanent magnet 2024 that cooperates with the winding 2023 is sleeved on the central shaft 2025.

[0054] In this embodiment, preferably, a guide nozzle 20210 is connected to the left end of the heat-resistant inner shell 2022. The guide nozzle 20210 is conical, which facilitates the guidance of the low-temperature molten salt passing through the rotating blade assembly 2028, so that the low-temperature molten salt can continue to flow and act on the electrode plate 103. A sealed bearing 20212 is embedded between the guide nozzle 20210 and the central shaft 2025, so that the low-temperature molten salt will not enter the heat-resistant inner shell 2022. The specific sealing technology is existing technology and will not be described in detail in this application. A stabilizing bearing 20211 is provided between the left end of the heat-resistant inner shell 2022 and the central shaft 2025, which provides support and stability for the central shaft 2025 and does not affect the rotation of the central shaft 2025.

[0055] In this embodiment, preferably, a bearing seat 2026 is provided at the right end of the heat-resistant inner shell 2022 to fix the right end of the central shaft 2025, which supports the right end of the central shaft 2025. A material cavity 2027 is left between the heat-resistant inner shell 2022 and the heat-resistant outer shell 2021 for the low-temperature molten salt to pass through. The annular material cavity 2027 plays a role in distributing and diffusing the low-temperature molten salt, which facilitates the diffusion of the columnar low-temperature molten salt. The diffused low-temperature molten salt fully contacts the surface of the electrode plate 103. The diffused low-temperature molten salt is relatively thin. Heating the thinly diffused low-temperature molten salt increases the heating sufficiency of the low-temperature molten salt.

[0056] In this embodiment, preferably, the preheating component 300 for preheating the bottom of the boiler body 100 includes:

[0057] A protective shell 301 is fixedly sleeved on the outer side of the lower end of the boiler body 100. The protective shell 301 is a ceramic fiber shell with poor thermal conductivity. A preheating cavity is left between the inside of the protective shell 301 and the outer surface of the boiler body 100 to facilitate the installation of the heating coil in the preheating cavity.

[0058] A side heating coil 302 is installed on the lower side of the boiler body 100, and the side heating coil 302 heats the side of the boiler body 100.

[0059] And a bottom heating coil 303 installed at the bottom of the preheating chamber, which heats the bottom of the boiler body 100. A connecting pipe 304 is provided between the bottom heating coil 303 and the side heating coil 302 and the energy storage box 201 to facilitate the supply of energy to the bottom heating coil 303 and the side heating coil 302.

[0060] In summary, during operation, cryogenic molten salt is supplied to the distribution pipe 101 from the outside. The cryogenic molten salt is then sprayed out at high speed through the nozzle. The high-speed sprayed cryogenic molten salt acts on the blades of the rotating blade assembly 2028, causing the blades to rotate and driving the central shaft 2025 to rotate. The central shaft 2025 then drives the permanent magnet 2024 to rotate. The permanent magnet 2024 cuts the magnetic field lines of the winding 2023 to generate electrical energy. The generated electrical energy is transmitted through the cable in the wiring pipe 203 to the battery in the energy storage box 201 for storage. The stored electrical energy is discharged to power the bottom heating coil 303 and the side heating coil 302. The bottom heating coil 303 and the side heating coil 302 heat the boiler body 100 and conduct the heat to the bottom of the boiler body 100 for preheating. The entire process realizes the conversion of the potential energy of the cryogenic molten salt into mechanical energy and then into electrical energy. Finally, it is converted into heat energy, playing a role in energy storage and conversion, and preheating the bottom of the boiler body 100, reducing the heat loss of the high-temperature molten salt falling to the bottom of the boiler body 100, keeping the high-temperature molten salt in a relatively suitable temperature range. The low-temperature molten salt passing through the rotating blade assembly 2028 flows into the material chamber 2027 along the guide nozzle 20210 and continues to flow to the right. During the flow, it diffuses through the annular material chamber 2027. The diffused low-temperature molten salt is relatively thin and acts on the electrode plate 103, allowing the columnar low-temperature molten salt to diffuse into a thinner annular low-temperature molten salt, which facilitates the full heating of the low-temperature molten salt. This solves the problem that the middle of the columnar low-temperature molten salt cannot be fully heated, increases the full heating of the low-temperature molten salt, and solves the problem of heat loss when the heated high-temperature molten salt falls to the bottom of the boiler body 100.

[0061] Example 2

[0062] Reference Figure 7 and Figure 8 This is the second embodiment of the present invention.

[0063] In this embodiment, preferably, by providing a mixing component 400, when the high-temperature molten salt falls to the bottom of the boiler body 100, the potential energy of the falling salt can drive the bottom blades 402 to rotate, thoroughly mixing the high-temperature molten salt at the bottom, ensuring that the overall temperature of the high-temperature molten salt remains uniform and does not exhibit temperature errors. This solves the problem of uneven heating caused by uneven temperature of the discharged high-temperature molten salt. Furthermore, the materials of all components in the mixing component 400 meet the temperature requirements of the high-temperature molten salt, ensuring that the use is not affected by high temperatures. The mixing component 400, installed inside the boiler body 100 for mixing high-temperature molten salt, includes:

[0064] A bottom ring 401 is horizontally installed inside the boiler body 100. An annular groove 403 is provided on the lower surface of the bottom ring 401. The cross-sectional shape of the annular groove 403 is not limited to the rectangle shown in this application, but can also be circular or wedge-shaped, etc.

[0065] Multiple bottom blades 402 are installed on the upper surface of the bottom ring 401 and are inclinedly distributed along its circumference. The curvature and inclination of the bottom blades 402 are convenient to adapt to the falling high-temperature molten salt and facilitate rotation under force.

[0066] An arc-shaped support block 404 extending into the annular groove 403 is provided on the inner surface of the lower end of the boiler body 100. The upper surface of the arc-shaped support block 404 is provided with ball bearings to reduce the contact area with the annular groove 403 and facilitate the rotation of the bottom ring 401.

[0067] In summary, during use, the low-temperature molten salt is heated to high-temperature molten salt on the electrode plate 103. The high-temperature molten salt is then pressurized by the pressurizing component 500 and falls onto the bottom blade 402. The bottom blade 402, under pressure, drives the bottom ring 401 to rotate, and the annular groove 403 rotates along the arc-shaped support block 404. The two do not separate vertically. As the bottom blade 402 rotates, the arc-shaped and inclined bottom blade 402 stirs the high-temperature molten salt at the bottom of the boiler body 100. The rotation of the bottom ring 401 does not restrict the distribution pipe 101 and the discharge pipe 102. The continuously falling high-temperature molten salt drives the bottom blade 402 to rotate, ensuring that the high-temperature molten salt is fully mixed. This results in a uniform temperature of the high-temperature molten salt in the boiler body 100, which is within a suitable temperature range. There will be no temperature errors in different parts of the high-temperature molten salt, increasing the convenience and stability of using the high-temperature molten salt.

[0068] Example 3

[0069] Reference Figure 9 This is the third embodiment of the present invention.

[0070] In this embodiment, preferably, an electrode plate 103 is vertically arranged inside the boiler body 100, located on the right side of the nozzle. The electrode plate 103 heats the low-temperature molten salt falling on its surface, heating it into high-temperature molten salt. A pressure member 500 is arranged at the lower end of the electrode plate 103, located above the right end of the bottom ring 401. Each component of the pressure member 500 is a high-temperature resistant component. The pressure member 500 can collect the high-temperature molten salt and pressurize it to fall onto the bottom blade 402. The high-temperature molten salt is then tilted onto the bottom blade 402 by the inclined pressure feed pipe 503, causing the bottom blade 402 to rotate and fully mix the high-temperature molten salt at the bottom of the boiler body 100.

[0071] In this embodiment, preferably, the pressurizing member 500 for pressurizing the high-temperature molten salt flowing along the surface of the electrode plate 103 includes:

[0072] A collection box 501 is fixedly sleeved on the lower end of the electrode plate 103. The lower end of the electrode plate 103 is flush with the top of the collection box 501. A groove is opened on the upper surface of the collection box 501 for collecting the high-temperature molten salt, which facilitates the collection of the high-temperature molten salt.

[0073] A piston plate 502 is vertically installed inside the collection box 501. The piston plate 502 fits against the inner wall of the collection box 501, which facilitates pushing the high-temperature molten salt to be discharged from the pressurized feed pipe 503. A miniature electric cylinder 505 is provided on the right side of the collection box 501 to drive the piston plate 502 to move.

[0074] In this embodiment, preferably, a plurality of pressurized feeding pipes 503 are provided on the lower surface of the collection box 501 near the right side. The shape of the pressurized feeding pipes 503 can be set as needed, and the pressurized feeding pipes 503 are inclined so that the discharged high-temperature molten salt acts inclined on the bottom blade 402, which facilitates the rotation of the bottom blade 402. The pressurized feeding pipes 503 are located on the left side of the piston plate 502. The right side of the collection box 501 is provided with an electric cylinder shell 504 that surrounds and protects the micro electric cylinder 505. The electric cylinder shell 504 is a high-temperature resistant shell, specifically referring to the material of the heat-resistant shell 2021, which can protect the micro electric cylinder 505.

[0075] In this embodiment, preferably, a discharge pipe 102 is provided through the bottom of the boiler body 100 to facilitate the discharge of high-temperature molten salt. Both the discharge pipe 102 and the distribution pipe 101 are equipped with switch valves.

[0076] In summary, during use, the high-temperature molten salt flows downward along the electrode plate 103 and is collected by the collection box 501. Then, the piston plate 502 is driven to move to the left by the micro electric cylinder 505, pushing the high-temperature molten salt in the collection box 501 to converge to the left. Part of it is discharged through the slot and falls onto the bottom blade 402 through gravitational potential energy, driving the bottom blade 402 to rotate. The other part is discharged through the pressurized feeding pipe 503. The pressurized high-temperature molten salt acts obliquely on the bottom blade 402, accelerating the rotation of the bottom blade 402 and driving the bottom ring 401 to rotate along the arc-shaped support block 404. The rotation of multiple bottom blades 402 allows the high-temperature molten salt gathered at the bottom of the boiler body 100 to be fully mixed, making the temperature of the high-temperature molten salt at the bottom uniform and preventing temperature errors. This increases the convenience and stability of using the high-temperature molten salt. When the low-temperature molten salt stops spraying, the bottom blade 402 stops rotating.

[0077] Example 4

[0078] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0079] In use, the potential energy of the low-temperature molten salt injection acts on the rotating blade assembly 2028, driving the central shaft 2025 to rotate, converting the potential energy into mechanical energy. The central shaft 2025 drives the permanent magnet 2024 and the winding 2023 to rotate relative to each other, cutting the magnetic field lines, converting the mechanical energy into electrical energy and storing it. The stored electrical energy is discharged to power the preheating component 300, converting the electrical energy into heat energy to preheat the bottom of the boiler body 100. This reduces heat loss when the high-temperature molten salt falls to the bottom of the boiler body 100. At the same time as the high-temperature molten salt falls, the pressurizing component 500 heats and acts on the mixing component 400, thoroughly mixing the high-temperature molten salt, making the temperature of the high-temperature molten salt uniform and maintaining a suitable temperature range, increasing the convenience and stability of using the high-temperature molten salt.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
