Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment and heat recovery technology, and in particular to a superconducting material waste gas heating carrier. Background Technology

[0002] Industrial production processes, especially in industries such as metallurgy, chemicals, and glass manufacturing, generate large amounts of high-temperature waste gas. Direct emission of this waste gas not only wastes energy but also causes thermal pollution to the environment. Currently, heat exchangers are commonly used to recover waste heat from waste gas; however, traditional heat exchangers suffer from low heat exchange efficiency, easy scaling, difficult cleaning and maintenance, and inability to adapt to fluctuations in waste gas temperature. In particular, when the waste gas contains dust or corrosive components, these particles easily deposit on the inner wall of the heat exchange tubes, severely affecting the heat exchange effect. Furthermore, cleaning is cumbersome, leading to decreased equipment operating efficiency and increased maintenance costs. Therefore, a superconducting material waste gas heating medium is needed to meet these needs. Summary of the Invention

[0003] The purpose of this invention is to provide a superconducting material waste gas heating carrier to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a superconducting material waste gas heating carrier, comprising a carrier body and a superconducting heat pipe. The carrier body is a cylindrical tank, with an injection pipe and a discharge pipe for injecting and discharging the carrier medium at its top and bottom, respectively. A first frame, which has an inverted U-shaped structure, is also fixedly installed on the top of the carrier body. A motor is installed on the top of the first frame, with the motor's output shaft extending downwards and connected to a first gear.

[0005] The superconducting heat pipe is an S-shaped coil, vertically arranged within the internal cavity of the carrier body. Both the top and bottom ends of the superconducting heat pipe are machined into right-angle bends, extending outwards through the center of the top and bottom ends of the carrier body, respectively. A core tube is fixedly installed on the vertical section of the right-angle bends extending from the top and bottom ends of the superconducting heat pipe. A second gear is installed on the outer wall of the core tube at the top end via a keyway and key connection. This second gear meshes with the first gear driven by the motor on the same horizontal plane.

[0006] A second frame is symmetrically arranged at the top and bottom of the carrier body. The second frame is L-shaped, and an electric telescopic rod is installed on its horizontal section. A connecting rod is installed on the output shaft of the electric telescopic rod, and a connecting pipe is fixed to the end of the connecting rod. A sleeve is provided at the end of the connecting pipe. The sleeve is used to fit over the core tube to achieve connection and sealing between the external pipe and the core tube.

[0007] Preferably, to ensure the airtightness of the carrier body and prevent leakage of the internal medium, the top center and bottom center of the carrier body are respectively sealed with the vertical sections of the right-angle bends at both ends of the superconducting heat pipe.

[0008] Preferably, one end of the core tube has a radially extending outer wall, forming a connecting portion with a smaller outer diameter. The second gear is then fitted and fixed onto this connecting portion with a smaller outer diameter.

[0009] Preferably, the height of the connecting portion with the smaller outer diameter of the core tube is greater than the thickness of the second gear. A sealing ring is embedded in the outer wall of the portion of the connecting portion that extends beyond the second gear to enhance the sealing effect when the tube sleeve is fitted.

[0010] Preferably, the depth of the cavity inside the sleeve is greater than the height of the part of the core tube that extends out of the second gear, ensuring that the sleeve can completely cover the extended section and make full contact with the sealing ring to achieve a reliable seal. At the same time, it prevents the friction between the end faces of the sleeve and the core tube from affecting the rotation of the second gear that drives the core tube and the superconducting heat pipe.

[0011] Preferably, inside the end of the core tube near the second gear, a plurality of circumferentially evenly arranged ball bearings are rolledly connected by bearings or similar structures. This ensures the smooth rotation of the core tube driven by the second gear, while the ball bearings exert an axial pressing effect on the second gear under the pressure of the sleeve, ensuring the meshing stability between the second gear and the first gear.

[0012] The beneficial effects of this utility model are: In this invention, an S-shaped coil structure superconducting heat pipe is used as the core heat exchange element, which increases the heat exchange area with the internal medium of the carrier body. At the same time, by utilizing the high thermal conductivity of superconducting materials, heat in the exhaust gas can be transferred to the carrier medium quickly and efficiently, which greatly improves the heat exchange efficiency.

[0013] In this invention, a motor drives a first gear, which in turn rotates a second gear fixed to the top of the superconducting heat pipe, causing the entire S-shaped superconducting heat pipe to rotate slowly within the carrier body. This rotation effectively disturbs the flow of the medium on its surface, improves the uniformity of heat exchange, and provides a self-cleaning effect on the pipe wall, preventing dirt deposition and maintaining long-term, high-efficiency heat exchange performance, making it particularly suitable for dusty exhaust gases.

[0014] This invention utilizes an electric telescopic rod to drive the connection and separation of the connecting pipe and sleeve from the core tube, enabling rapid connection and disconnection between the external pipe and the heating carrier. Combined with the sealing ring on the core tube and the internal ball bearing design, the connection process is smooth and reliably sealed, greatly facilitating the installation, maintenance, and repair of the equipment.

[0017] 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.

[0018] Reference Figure 1-5 A superconducting material waste gas heating carrier is mainly composed of a carrier body 1 and a superconducting heat pipe 2. The carrier body 1 is a sealed cylindrical metal tank used to hold the carrier medium such as the liquid or phase change material to be heated. A liquid injection pipe 3 is provided at the top and a liquid discharge pipe 4 is provided at the bottom.

[0019] The superconducting heat pipe 2 is made of superconducting material and is bent into an S-shaped coil, vertically installed inside the carrier body 1. Its top and bottom ends are both 90-degree right-angle bends, extending outwards through the central holes at the top and bottom of the carrier body 1, respectively. These two protruding parts are rigorously sealed with high-performance sealing material to ensure the airtightness of the carrier body 1. A core tube 8 is welded to the vertical sections of the right-angle bends extending from the top and bottom ends of the superconducting heat pipe 2. An exhaust gas duct (not shown in the figure) is connected to these two core tubes 8 via a connection mechanism described later, allowing exhaust gas to flow through the superconducting heat pipe 2, and heat to be transferred to the medium inside the carrier body 1 through the wall of the superconducting heat pipe 2.

[0020] To enable the rotation of the superconducting heat pipe 2 for efficient heat exchange and self-cleaning, a first U-shaped frame 5 is installed on the top of the carrier body 1, on which a motor 6 is fixed. The output axis of the motor 6 is downward and connected to a first gear 7 (small gear). On the core tube 8 at the top, a second gear 9 (large gear) is installed via a key connection, which meshes horizontally with the first gear 7. When the motor 6 is started, it drives the superconducting heat pipe 2 to slowly rotate around its central axis within the carrier body 1, agitating the medium and removing any dirt that may adhere to the pipe wall.

[0021] To facilitate the connection and disconnection of external exhaust gas pipelines with this device, and for the replacement of worn seals and equipment maintenance, an L-shaped second frame 10 is installed at the top and bottom of the carrier body 1. An electric telescopic rod 11 is installed on the horizontal section of each second frame 10. The output end of the electric telescopic rod 11 is connected to a connecting pipe 13 via a connecting rod 12, and a sleeve 14 is fixed to the end of the connecting pipe 13. When connection is needed, the electric telescopic rod 11 extends, pushing the sleeve 14 onto the corresponding core tube 8; when disconnection is needed, the electric telescopic rod 11 retracts, causing the sleeve 14 to separate from the core tube 8.

[0022] To improve the sealing and ease of connection, the core tube 8 is designed as a stepped shaft, with a smaller outer diameter at the portion that mates with the sleeve 14. The second gear 9 is fitted onto the smaller-diameter section of the core tube 8, where the height of the smaller-diameter section is greater than the thickness of the second gear 9. A groove is formed on the outer wall of the protruding part, and a sealing ring 15 is embedded within it. The depth inside the sleeve 14 is sufficient to completely cover this section of the shaft with the sealing ring 15, ensuring a good seal after connection. Furthermore, a ring of ball bearings 16 is installed inside the end of the core tube 8 to ensure smooth rotation of the core tube 8 driven by the second gear 9. Simultaneously, the ball bearings 16 exert an axial pressing effect on the second gear 9 under the pressure of the sleeve 14, ensuring stable meshing between the second gear 9 and the first gear 7.

[0023] Working principle: During operation, the electric telescopic rod 11 first securely attaches the sleeves 14 at both ends to the corresponding core tubes 8, achieving a sealed connection with the external exhaust gas pipeline system. High-temperature exhaust gas enters the superconducting heat pipe 2 through the core tube 8 from one end connecting pipe 13, flows through the S-shaped coil, and exits from the other end of the core tube 8. During this process, the heat carried by the exhaust gas is efficiently transferred through the tube wall of the superconducting heat pipe 2 to the medium (such as water, heat transfer oil, or phase change material) within the carrier body 1, raising its temperature. The heated medium can be drained and utilized through the drain pipe 4. Simultaneously, the motor 6 can be started intermittently or continuously to drive the superconducting heat pipe 2 to rotate slowly, achieving self-cleaning and enhanced heat exchange. When maintenance or repair is required, the external pipeline is disconnected, and the electric telescopic rod 11 is retracted, separating the sleeves 14 from the core tubes 8, thus isolating the device from the system. Operation is very convenient.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
