Description

Technical Field

[0001] This utility model relates to the technical field of shell-and-tube graphite heat exchangers, specifically a carbon fiber reinforced shell-and-tube graphite heat exchanger. Background Technology

[0002] Shell-and-tube graphite heat exchangers are widely used in many industrial fields such as chemical, pharmaceutical, and food processing. Thanks to the excellent corrosion resistance of graphite, they can meet the heat exchange requirements of various highly corrosive media. In strong acid environments such as sulfuric acid and hydrochloric acid, metal heat exchangers are easily corroded and damaged, while graphite heat exchangers can operate stably, ensuring normal production.

[0003] The existing carbon fiber reinforced shell-and-tube graphite heat exchangers have the following drawbacks: Traditional equipment has insufficient thermal insulation design, resulting in a large amount of ineffective heat loss. Heat energy is transferred to the equipment shell and supporting structure, which not only reduces heat exchange efficiency and increases energy consumption, but may also cause high temperature effects on the working environment and pose safety hazards. To address these issues, we propose a carbon fiber reinforced shell-and-tube graphite heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a carbon fiber reinforced shell-and-tube graphite heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber reinforced shell-and-tube graphite heat exchanger, comprising a rectangular fixing plate, a heat exchanger bottom shell, and a heat exchanger outer shell. Four expansion bolts are installed around the bottom perimeter of the rectangular fixing plate, and four vibration damping components are installed around the top perimeter of the rectangular fixing plate. When the four expansion bolts are installed around the bottom perimeter of the rectangular fixing plate, they provide stable support and fixation at the four corners of the rectangular fixing plate. The main function of the vibration damping components is to absorb and dissipate vibration energy. When equipment or structures mounted on the rectangular fixing plate vibrate, the vibration damping components... The damping component can convert vibration energy into other forms of energy such as heat energy, thereby reducing the transmission of vibration to the surrounding environment or other components. One end of the damping component is equipped with a heat insulation plate, and the heat exchanger bottom shell and heat exchanger outer shell are installed on both sides of the heat insulation plate through limiting and fixing rods. The main function of the limiting and fixing rods is to ensure the stability and accuracy of the heat exchanger bottom shell and heat exchanger outer shell during installation, and to prevent them from shifting or deforming during operation. The heat insulation plate effectively isolates the heat generated by the heat exchanger during operation from the surrounding environment, improves thermal efficiency, and also protects the surrounding equipment and personnel from the effects of high temperature.

[0006] Preferably, a fan is installed at the middle position of the rear side wall of the heat exchanger bottom shell, and an external power supply socket is fixed to the rear side wall of the heat exchanger bottom shell. During operation, the fan can generate airflow to accelerate the heat dissipation of the heat exchanger bottom shell and its internal components, effectively preventing performance degradation or damage caused by overheating. The external power supply socket allows users to provide a stable and reliable power supply to the fan, ensuring the continuous and efficient operation of the fan.

[0007] Preferably, two heating power seats are installed inside the bottom shell of the heat exchanger. Heating tubes are installed on the heating power seats and fixed to the heating power seats by limiting and fixing plates. The limiting and fixing plates not only enhance the connection stability between the heating tubes and the heating power seats, but also effectively prevent the heating tubes from shaking or falling off during operation, ensuring heating efficiency and safety. The heating tubes are filled with a heat-conducting medium with a high thermal conductivity, which can quickly respond to the heat transferred by the heating power seats and transfer the heat evenly and efficiently to the fluid inside the heat exchanger, thereby improving the overall heat exchange efficiency.

[0008] Preferably, a heat dissipation mesh is fixed on the front surface of the heat exchanger shell. The heat dissipation mesh is made of perforated metal mesh or woven metal wire mesh. This material has good air permeability and heat dissipation performance, which can effectively increase the heat dissipation area of ​​the heat exchanger shell and accelerate the dissipation of heat. The heat dissipation mesh enhances the heat dissipation performance of the heat exchanger and also ensures the robustness and durability of the structure, enabling it to operate stably in various harsh working environments.

[0009] Preferably, the heat exchanger shell and the heat exchanger bottom shell are made of carbon fiber composite material and are fixedly connected by a snap-fit ​​structure. Carbon fiber composite material has excellent properties such as high strength, high modulus, low density, corrosion resistance and high temperature resistance, which makes the heat exchanger shell and the heat exchanger bottom shell have better structural strength and thermal stability. The snap-fit ​​structure simplifies the assembly process, improves assembly efficiency, and can also ensure a tight connection between the heat exchanger shell and the heat exchanger bottom shell to prevent fluid leakage.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The main function of the limiting and fixing rod of this utility model is to ensure the stability and accuracy of the heat exchanger bottom shell and the heat exchanger outer shell during installation, preventing displacement or deformation during operation. The heat insulation plate effectively isolates the heat generated by the heat exchanger during operation from the surrounding environment, improving thermal efficiency and protecting surrounding equipment and personnel from high temperatures. The limiting and fixing plate not only enhances the connection stability between the heating tube and the heating power base, but also effectively prevents the heating tube from shaking or falling off during operation, ensuring heating efficiency and safety. The heating tube is filled with a heat-conducting medium with a high thermal conductivity, which can quickly respond to the heat transferred by the heating power base, and transfer the heat evenly and efficiently to the fluid inside the heat exchanger, improving the overall heat exchange efficiency.
