Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a shell and tube heat exchanger. Background Art

[0002] Steam heat exchangers are a common type of heat exchange equipment used in industrial production, and are widely used in the chemical, pharmaceutical, and food processing industries. Traditional shell-and-tube heat exchangers are primarily composed of a shell, tube bundles, and headers. Their basic principle is to transfer heat through heat exchange between the fluid in the tubes and the fluid in the shell.

[0003] However, traditional heat exchangers have some shortcomings in practical applications, such as low heat exchange efficiency. Due to the uneven distribution of fluid inside the traditional heat exchanger, local overheating or overcooling can easily occur, thereby affecting the heat exchange effect. Especially in application scenarios that require rapid heating or cooling, traditional heat exchangers often cannot meet the needs of high efficiency and rapid response. For some temperature-sensitive processes, this uneven temperature distribution may lead to a decline in product quality. Utility Model Content

[0020] The present application provides a shell-and-tube heat exchanger that utilizes a circulation assembly to effectively control the circulation of hot steam within the main body, thereby avoiding uneven heat exchange caused by hot air concentrating at the top, thereby effectively improving heat exchange efficiency. The flow tubes and heat exchange fins arranged in a serpentine structure greatly increase the contact area between the liquid and the steam, extending the residence time of the liquid within the heat exchanger, thereby improving heat exchange efficiency. The shell-and-tube heat exchanger is described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments.

[0021] The following describes the present application in detail with reference to the accompanying drawings and specific implementation methods. Figure 1-5 In the embodiment 1 provided in this embodiment, the shell and tube heat exchanger mainly includes a shell and tube heat exchanger, including: a main body 1, the main body 1 is configured as a frame structure as a whole, and the bottom of the main body 1 is hollowed out; a heat conducting component, the heat conducting component is arranged inside the main body 1, and is used to guide water flow through and heat it quickly; and a circulation component, the circulation component is arranged on both sides of the main body 1, and is used to control the circulation of hot steam inside the main body 1 to improve heating efficiency;

[0022] During use, the main body 1 serves as the basic frame of the entire heat exchanger, providing space for installing and fixing other components. The main body 1 is arranged in a frame structure as a whole, and the bottom is hollowed out to allow external hot steam to enter the interior of the device, and use the heat conduction component and circulation component to quickly heat the water flow.

[0023] Furthermore, the heat conduction component includes: a heat exchange chamber 101 provided inside the main body 1 for accommodating high-temperature steam; a flow pipe 102 provided inside the main body 1, the flow pipe 102 is located inside the heat exchange chamber 101, and the two ends of the flow pipe 102 are respectively connected to a liquid inlet pipe 102a and a liquid outlet pipe 102b that pass through the main body 1, and the flow pipe 102 is arranged in a serpentine structure as a whole;

[0024] During use, liquid enters flow tube 102 through liquid inlet pipe 102a, exchanges heat with steam within flow tube 102, and is then discharged through liquid outlet pipe 102b. Heat exchange chamber 101, located within main body 1, accommodates high-temperature steam. After entering the heat exchange chamber, the high-temperature steam contacts flow tube 102, exchanging heat. The serpentine structure increases the contact area between the liquid and steam, prolonging the liquid's residence time within the heat exchanger and improving heat exchange efficiency.

[0025] Furthermore, a plurality of heat exchange fins 103 are provided on the surface of the flow tube 102, and the plurality of heat exchange fins 103 are equidistantly distributed along the axial direction of the flow tube 102. During use, the heat exchange fins 103 increase the surface area of ​​the flow tube 102, which helps to enhance heat exchange and thereby improve the efficiency of heat exchange.

[0026] Furthermore, a convex plate 103a is provided at the bottom of the heat exchange plate 103, and a conical structure is formed between the heat exchange plate 103 and the convex plate 103a. The conical structure formed between the convex plate 103a and the heat exchange plate 103 helps to improve the fluid dynamic characteristics through design, so that water condensed from steam is quickly formed around the flow tube 102 and discharged downward, preventing water droplets from adhering to and affecting heat exchange.

[0027] Furthermore, a console 3 is provided on one side of the main body 1 , and two control ports 301 are provided on the surface of the console 3 for connecting to a production line host.

[0028] Example 2

[0029] On the basis of Example 1, the circulation component includes: two pairs of mounting pads 105 provided on both sides of the main body 1, each pair of mounting pads 105 is composed of two long plates, and the two pairs of mounting pads 105 are distributed along the longitudinal direction; a plurality of drive motors 2 provided on one side of the main body 1, and the plurality of drive motors 2 are respectively provided in the two pairs of mounting pads 105; a plurality of matching platforms 201 provided on the other side of the main body 1, and the plurality of matching platforms 201 are respectively opposite to the plurality of drive motors 2; a central shaft 202 provided between the drive motor 2 and the matching platform 201, the drive motor 2 and the central shaft 202 are driven and connected, and a plurality of groups of annular fan blades 203 are provided on the surface of the central shaft 202, and the fan blades 203 located above and the fan blades 203 located below are arranged in opposite directions;

[0030] During use, the mounting pad 105 is used to fix the drive motor 2 and the matching platform 201, thereby providing a stable mounting foundation and ensuring the position accuracy of the drive motor 2 and the matching platform 201. During the heating process, the fan blades 203 are driven to rotate by rotating the central axis 202 of the drive motor 2, providing power for the circulation of steam. At this time, the steam will circulate above and below the flow tube 102. The circulating flow prevents the hot air from being at the top and difficult to contact the flow tube 102 and exchange heat, thereby improving the efficiency of the heat exchange.
