[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figure 1-2 A high-temperature resistant and high-efficiency tubular heat exchanger includes a support frame 1, on which a horizontally arranged heat exchange shell 2 is mounted. The support frame 1 serves as the supporting structure for the entire heat exchanger, ensuring its stability and safety. The horizontal arrangement of the heat exchange shell 2 on the support frame 1 effectively utilizes its internal space, facilitating the formation of multiple heat exchange chambers and improving heat exchange efficiency. Preferably, the heat exchange shell 2 is mounted on the support frame 1 using several spring dampers 15, which effectively reduces vibration and noise generated during operation. An elastic buffer pad 16 is also installed at the bottom of the support frame 1, further enhancing the shock absorption effect and improving the stability and safety of the heat exchanger.

[0022] An input inner liner 3 and an output inner liner 4 are rotatably mounted on both sides of the heat exchange shell 2. Both the input inner liner 3 and the output inner liner 4 are installed inside the heat exchange shell 2 through a rotary dynamic seal 12, allowing the input inner liner 3 and the output inner liner 4 to rotate relative to the heat exchange shell 2, thereby enhancing the heat exchange effect. An input heat exchange cavity 6 is formed in the heat exchange shell 2 at the input inner liner 3, and an output heat exchange cavity 8 is formed in the heat exchange shell 2 at the output inner liner 4. An intermediate heat exchange cavity 7 is formed in the heat exchange shell 2 between the input inner liner 3 and the output inner liner 4. The arrangement of the input heat exchange cavity 6, the intermediate heat exchange cavity 7, and the output heat exchange cavity 8 allows the fluid to undergo sufficient heat exchange in different chambers. Several heat exchange pipes 5 are connected between the input inner liner 3 and the output inner liner 4, passing through the intermediate heat exchange cavity 7, to connect the input inner liner 3 and the output inner liner 4, forming an effective heat exchange channel. Preferably, the heat exchange fins installed on the heat exchange pipes 5 further increase the heat exchange area and improve the heat exchange efficiency.

[0023] An input pipe 9, penetrating the heat exchange shell 2, is connected to the input inner liner 3. An output pipe 11, also penetrating the heat exchange shell 2, is connected to the input inner liner 3. Rotary dynamic seals 12 are installed at the junctions of the input pipe 9, the output pipe 11, and the heat exchange shell 2. Rotary joints 13 are installed on both the input pipe 9 and the output pipe 11. A power device 10 for driving the rotation of the input pipe 9 or the output pipe 11 is also installed on the support 1. The input pipe 9 and the output pipe 11 are connected to the input inner liner 3 and the output inner liner 4, respectively, realizing the input and output of fluid. The rotary joints 13 installed on the input pipe 9 and the output pipe 11 allow the pipes to maintain fluid flow while rotating. The introduction of the power device 10 provides power for the rotation of the input pipe 9 or the output pipe 11. Preferably, the power device 10 is a geared motor, and the motor shaft of the geared motor is connected to the input pipe 9 or the output pipe 11 via a transmission gear.

[0024] To facilitate cleaning of the interior of the input inner tank 3 and the output inner tank 4, such as to facilitate the insertion of a flexible hose to drain condensate, water extraction holes are provided on the input pipe 9 and the output pipe 11 on the outside of the heat exchange shell 2. The water extraction holes are sealed by a sealing plug 17.

[0025] In order to allow fluid to enter and exit, inlet and outlet pipes 14 are connected to the inlet heat exchange chamber 6, the intermediate heat exchange chamber 7 and the outlet heat exchange chamber 8.

[0026] The input inner liner 3, the output inner liner 4, and the heat exchange pipe 5 are all made of high-temperature resistant materials, such as titanium alloys and high-temperature resistant ceramic materials, which can maintain stable physical and chemical properties in high-temperature environments, thus ensuring the long-term stable operation of the heat exchanger.

[0027] Description of the specific working process of this application:

[0028] I. Fluid Input and Preliminary Heat Exchange

[0029] Hot fluid enters the input liner 3 through the input pipe 9, and cold fluid is input into the input heat exchange chamber 6 through the corresponding pipe, so that the hot fluid and cold fluid can carry out preliminary heat exchange in the input heat exchange chamber 6;

[0030] II. High-efficiency heat exchange process

[0031] Hot fluid flows from the input inner tank 3 to the output inner tank 4 through the heat exchange pipe 5, while cold fluid is simultaneously introduced into the intermediate heat exchange chamber 7 through corresponding pipes.

[0032] Since the heat exchange pipe 5 is installed through the intermediate heat exchange chamber 7, the hot fluid will also exchange heat with the cold fluid in the intermediate heat exchange chamber 7 during the flow process.

[0033] Secondly, the power equipment 10 drives the input pipe 9 to rotate the heat exchange pipe 5 through the input inner tank 3, which enhances the disturbance and mixing of the cold fluid and improves the heat exchange efficiency.

[0034] III. Fluid Output and Heat Recovery

[0035] After sufficient heat exchange, the hot fluid is discharged from the output inner tank 4 through the output pipe 11, while at the same time, cold fluid is input into the output heat exchange chamber 8 through the corresponding pipe, so that the hot fluid and cold fluid can exchange heat again.

[0036] Through three heat exchange processes—input heat exchange chamber 6, intermediate heat exchange chamber 7, and output heat exchange chamber 8—the hot fluid has transferred most of its heat to the cold fluid, achieving heat recovery and utilization.

[0037] The recovered heat can be used in various industrial processes or heating systems, improving energy efficiency.

[0038] Meanwhile, because the heat exchanger is made of high-temperature resistant materials, it can operate stably for a long time in high-temperature environments, ensuring the continuous recovery and utilization of heat.

[0039] IV. Vibration Reduction and Stability

[0040] The heat exchange shell 2 is mounted on the bracket 1 by a spring damper 15, which effectively reduces the vibration and noise generated by the heat exchanger during operation.

[0041] The elastic buffer pad 16 at the bottom of the bracket 1 further enhances the shock absorption effect and improves the stability and safety of the heat exchanger.

[0042] In summary, this high-temperature resistant and high-efficiency tubular heat exchanger, through its unique design and structure, achieves efficient heat exchange and heat recovery and utilization between fluids. At the same time, its vibration damping design and stability assurance also ensure the long-term stable operation of the heat exchanger in high-temperature environments.
