[0002] In the blast furnace gas ammonia synthesis process, heat exchange equipment is a key component for achieving heat energy transfer and utilization. However, traditional heat exchange equipment often adopts an integral or welded structure, which leads to many inconveniences in equipment maintenance, replacement or cleaning.

[0003] Traditional heat exchange equipment has a compact structure and lacks sufficient disassembly space between components, which makes the disassembly process take a lot of time. In addition, since the connection parts are welded or otherwise fixed, special tools are required for disassembly, and even destructive disassembly of the equipment may be required, resulting in equipment damage and increased repair costs. It may also affect the normal operation and production efficiency of the equipment, and has poor applicability. Utility Model Content

[0013] The temperature measuring component comprises a temperature sensor fixedly connected to the outer end of the spring bracket, and the top end of the support rod passes through the machine body and is fixedly connected to a display screen.

[0014] The bottom of the exchange tube is in contact with and connected above the support plate and the spring bracket, and the top of the support plate is provided with a groove adapted to the exchange tube.

[0028] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0029] like Figure 1-8 As shown, a new type of heat exchange equipment in the blast furnace gas synthesis ammonia process includes a base 10, the top of the base 10 is fixedly connected to the body 11, and the inner cavity of the body 11 is welded with a support plate 13:

[0030] The heat exchange structure 20 includes an exchange tube 21 fixedly connected to the body 11, and a flange 22 is fixedly connected to the exchange tube 21;

[0031] The bracket structure 30 includes a support rod 31 fixedly connected to the top of the base 10, the outer ring of the support rod 31 is fixedly connected to a spring bracket 32, and the outer end of the spring bracket 32 ​​is connected to a temperature measuring component 33;

[0032] When the hot material and the cold material are located in the exchange tube 21, heat exchange is completed by the hot material and the cold material radiating and absorbing heat in the exchange tube 21;

[0033] The exchange tube 21 is a modular structure, which is convenient for maintenance. The temperature measuring component 33 detects the temperature in different exchange tubes 21 to determine whether the exchange tube 21 is blocked by detecting the temperature.

[0034] It should be noted that an arc-shaped bracket is provided at the outer end of the spring bracket 32, and the main body of the spring bracket 32 ​​is a spring folding rod.

[0035] In this embodiment, when heat exchange is performed, hot material and cold material are respectively introduced into the inner cavity of the exchange tube 21, and heat transfer is performed in the exchange tube 21. After the heat exchange is completed, the hot material and cold material are discharged from the bottom of the exchange tube 21. At the same time, during the heat exchange process, the temperature measurement component 33 detects the temperature of the hot material cavity of each section of the exchange tube 21 in real time, so as to determine whether blockage or other conditions occur through the different temperatures of each section of the exchange tube 21. If blockage or other faults occur, the flanges 22 at the upper and lower ends of the faulty exchange tube 21 can be removed and removed separately, which is convenient for precise disassembly and maintenance.

[0036] like Figure 2 As shown, the outer ring of the middle section of the body 11 is threadedly connected with a foldable protective cover 12 via bolts.

[0037] It should be noted that the bottom of the exchange tube 21 passes through the foldable protective cover 12, and the foldable protective cover 12 is divided into two parts, and the middle parts of the two parts are hinged together by a hinge.

[0038] In this embodiment, the bolts connecting the foldable protective cover 12 and the machine body 11 are unscrewed, and the half of the foldable protective cover 12 that is not in contact with the exchange tube 21 is rotated to fold the two foldable protective covers 12 together, and then the foldable protective cover 12 is pulled outward and separated from the exchange tube 21 to complete the disassembly of the foldable protective cover 12.

[0039] like Figure 5-7 As shown, a middle heat conduction plate 211 is welded to the inner cavity of the exchange tube 21, and the inner cavity of the exchange tube 21 is divided by the heat conduction plate 211. The upper half of the inner cavity of the exchange tube 21 is divided into a cold material cavity, and the lower half is a hot material cavity, and inlets and outlets are provided at the upper and lower ends of the hot material cavity and the cold material cavity.

[0040] It should be noted that the heat conducting plate 211 is an S-shaped spiral heat conducting plate, and the main body of the heat conducting plate 211 is made of copper.

[0041] In this embodiment, the hot material and the cold material are introduced into the hot material cavity and the cold material cavity respectively, and the temperature is transferred over a large area through the S-shaped heat conducting plate to achieve heat exchange.

[0042] like Figure 8 As shown, the temperature measuring component 33 includes a temperature sensor 331 fixedly connected to the outer end of the spring bracket 32, and the top end of the support rod 31 passes through the body 11 and is fixedly connected to a display screen 332.

[0043] It should be noted that the inner cavity of the support rod 31 is pre-buried with data lines and electrical wires for connecting the temperature sensor 331 and the display screen 332 .

[0044] In this embodiment, the temperature of the hot material chamber of each section of the exchange tube 21 is detected in real time by the temperature sensor 331, and the detected temperature is transmitted to the display screen 332. If the temperature difference between adjacent exchange tubes 21 is too large, it can be determined that the front section of the exchange tube 21 is blocked, thereby affecting the heat exchange.

[0045] like Figure 3-4 As shown, the bottom of the exchange tube 21 is in contact with the support plate 13 and the top of the spring bracket 32 ​​, and the top of the support plate 13 is provided with a groove adapted to the exchange tube 21 .

[0046] In this embodiment, when the exchange tube 21 is removed, the spring bracket 32 ​​needs to be pushed and folded to separate the exchange tube 21 from the support and limit of the spring bracket 32 ​​before the exchange tube 21 can be removed.

[0047] The working principle of the utility model is as follows: when performing heat exchange work, the hot material and the cold material are respectively introduced into the hot material cavity and the cold material cavity of the exchange tube 21, and the hot material and the cold material transfer heat to each other through the heat conducting plate 211 in the exchange tube 21 to realize heat exchange, and are discharged through the outlet at the bottom of the exchange tube 21 after completion. When performing heat exchange, the spring bracket 32 ​​is close to the bottom of the hot material cavity of the exchange tube 21, so that the temperature of the hot material cavity of each section of the exchange tube 21 is detected by the temperature sensor 331, and the real-time temperature is transmitted to the display screen 332. By observing the temperature of each section of the exchange tube 21, it is judged whether a fault occurs. If the temperature difference between adjacent exchange tubes 21 is too large, it can be judged that the front section of the exchange tube 21 has a blockage or other fault, then the folding cover 12 is removed, and the flanges 22 at the upper and lower ends of the faulty exchange tube 21 are unscrewed, and then the spring bracket 32 ​​is pushed to fold and shrink, so that the exchange tube 21 is separated from the support and limit of the spring bracket 32, and then the exchange tube 21 is taken out, so as to realize the separate disassembly of the faulty exchange tube 21, which is convenient for maintenance.

[0048] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be regarded as the protection scope of this utility model. The structures, devices and operating methods not specifically described and explained in this utility model shall be implemented according to the conventional means in this field unless otherwise specified and limited.
