Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, and in particular to a graphite-based corrosion-resistant heat exchange equipment. Background Technology

[0002] Heat exchange equipment is used to transfer heat from a hot fluid to a cold fluid. It is an industrial application of convective heat transfer and heat conduction. It plays a core role in industrial and daily life by efficiently transferring heat between different media to achieve temperature control and energy conversion. In the existing technology, the tube sheet and heat exchange tube of heat exchangers are usually made of metal. The overall heat exchange effect of the equipment is poor, the corrosion resistance is not good, it is easy to crystallize and stick to the wall, and pitting corrosion exists. Utility Model Content

[0003] Therefore, it is necessary to provide a graphite-based corrosion-resistant heat exchange device to address the above problems, which can effectively avoid the occurrence of easy damage to heat exchange tubes and low heat exchange efficiency.

[0004] A graphite-based corrosion-resistant heat exchange device includes a heat exchange shell, a first liquid inlet pipe installed on one side of the heat exchange shell, a first liquid outlet pipe installed on the side of the heat exchange shell opposite to the first liquid inlet pipe, a second liquid inlet pipe and a second liquid outlet pipe installed on the heat exchange shell, and a graphite tube array installed inside the heat exchange shell, with one end of the graphite tube array connected to the second liquid inlet pipe and the other end of the graphite tube array connected to the second liquid inlet pipe.

[0005] As a preferred embodiment, a first heating plate is installed on the inner top surface of the heat exchange shell, and a second heating plate is installed on the inner bottom surface of the heat exchange shell. Both the first heating plate and the second heating plate are equipped with metal guide plates.

[0006] As a preferred embodiment, a mounting plate is provided on the side of the heat exchange housing, and first clamping plates are installed on both the left and right sides of the mounting plate. Two second clamping plates are installed on the mounting plate to cooperate with the first clamping plates to clamp the heat exchange housing. The first clamping plates are connected to the second clamping plates by fasteners.

[0007] The advantages of this utility model are:

[0008] The heat exchange shell has two flow paths for the fluid medium to facilitate heat exchange between two media at different temperatures. The tube bank is composed of multiple continuous graphite tubes connected as one unit, forming multiple S-shaped sections. Both media inside and outside the graphite tube bank are in contact with the tube walls. Compared to metal heat exchange tubes, the graphite tube bank has better corrosion resistance and improves the overall heat conversion efficiency by increasing the heat exchange area.

[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] like Figures 1-4 As shown,

[0018] As an optional embodiment,

[0019] A graphite-based corrosion-resistant heat exchange device includes a heat exchange shell 1, a first liquid inlet pipe 2 installed on one side of the heat exchange shell 1, a first liquid outlet pipe 3 installed on the side of the heat exchange shell 1 opposite to the first liquid inlet pipe 2, a second liquid inlet pipe 4 and a second liquid outlet pipe 5 installed on the heat exchange shell 1, and a graphite tube array 9 installed inside the heat exchange shell 1, with one end of the graphite tube array 9 connected to the second liquid inlet pipe 4 and the other end of the graphite tube array 9 connected to the second liquid inlet pipe 4.

[0020] Specifically, two fluid media at different temperatures both operate within a heat exchange shell, which has two flow paths for the fluid media. The first path involves the fluid entering the heat exchange shell through a first inlet pipe and exiting through a first outlet pipe. The second path involves the fluid entering through a second inlet pipe, then flowing into multiple graphite tube arrays, and finally exiting through a second outlet pipe. One of these paths allows the higher-temperature fluid to enter, thus heating the medium in the other path and achieving heat exchange. Furthermore, the graphite tube array 9, as the heat transfer material for both media, has an extremely low coefficient of thermal expansion and excellent heat resistance. Both media are in contact with the tube walls of the graphite tube array 9, providing better corrosion resistance compared to metal heat exchange tubes. The array consists of multiple continuous graphite tubes connected together, forming an overall S-shape. (See reference for details.) Figure 2 ,or Figure 3 The diameter of the graphite tubes in the tube bank is relatively smaller than that of the second liquid inlet pipe 4 and the second liquid outlet pipe 5. Therefore, after multiple graphite tube banks 9 are connected to the inlet and outlet pipes, the medium flowing inside them can flow into multiple graphite tube banks 9, increasing the contact area with the high-temperature medium, thereby improving the overall heat conversion efficiency.

[0021] Based on the above embodiments, further improvements are made as follows:

[0022] Firstly, a first heating plate 10 is installed on the inner top surface of the heat exchange shell 1, and a second heating plate 11 is installed on the inner bottom surface of the heat exchange shell 1. Metal guide plates 13 are installed on both the first heating plate 10 and the second heating plate 11. Furthermore, to further reduce the impact of heat loss, heating plates are installed on both the upper and lower surfaces of the inner wall of the heat exchange shell 1, and metal guide plates are installed on the heating plates. This allows the metal guide plates to be heated to provide more heat and reach the desired temperature. Additionally, see [further details omitted]. Figure 4 The metal guide vane can guide the directional flow of high-temperature media.

[0023] Secondly, a mounting plate 6 is provided on the side of the heat exchange housing 1. First clamping plates 7 are installed on both the left and right sides of the mounting plate 6. Two second clamping plates 8 are installed on the mounting plate 6 to cooperate with the first clamping plates 7 to clamp the heat exchange housing 1. The first clamping plates 7 are connected to the second clamping plates 8 by fasteners. The mounting plate 6 can be fixed to the external workbench or wall. The first clamping plates 7 and the second clamping plates 8 can cooperate to quickly clamp and fix the heat exchange housing 1. Subsequently, the distance between the first clamping plates 7 and the second clamping plates 8 can be adjusted by operating the fasteners to clamp and fix heat exchange housings 1 of different sizes.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
