[0031] according to Figure 1 - Figure 3 As shown, the bottom of the left and right ends of the body 1 are respectively connected with an air intake valve pipe 5 and a liquid intake valve pipe 4, and high-precision detection sensors are built in the interior of the air intake valve pipe 5 and the liquid intake valve pipe 4. The bottom wall surface of the body 1 is connected with a decontamination and discharge valve pipe 7. When the heat exchanger needs to be operated, the air intake valve pipe 5 is opened to allow air or specific gas to enter the bottom of the body 1 through the high-precision detection sensor. The high-precision detection sensor monitors the gas flow and pressure in this process.

[0033] according to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a sealing partition plate 23 is installed inside the air intake partition end 9 and the tube bundle bent connecting end 8, the top of the air intake partition end 9 is connected to a heat transfer channel 21, the top of the heat transfer channel 21 is connected to a secondary heat exchange pipeline 20, and the top of the secondary heat exchange pipeline 20 is connected to the device body 14. After the gas enters the device body 1 from the air intake valve pipe 5, the sealing partition plate 23 inside the air intake partition end 9 and the tube bundle bent connecting end 8 can make the airflow entering the device body evenly distributed to avoid direct impact, and the evenly distributed gas then enters the heat transfer channel 21, and is transported to the device body 14 through the secondary heat exchange pipeline 20, thereby further improving the heat exchange efficiency.

[0034] according to Figure 5 As shown, the inside of the heat transfer channel 21 is slidably plugged with a regulating valve plate 24, and a double-axis pneumatic gas rod 25 is installed on the side end of the regulating valve plate 24. When entering the device body 14, the PLC controller 3 sends a command to the double-axis pneumatic gas rod 25, driving the regulating valve plate 24 to move left and right in the heat transfer channel 21, thereby changing the cross-sectional area of ​​the heat transfer channel 21, finely adjusting the gas flow rate and flow rate, and forming a dynamic adjustment that helps to maintain the ideal heat exchange efficiency and system stability, and further ensures the pressure regulation during the operation of the device body 1.

[0035] according to Figure 1 - Figure 3As shown, the top wall surface of the body 1 is connected to a circulation exchange tube 19, and the top end of the circulation exchange tube 19 is connected to an exchange filter 18. The exchange filter 18 is installed on the outside of the body 2 14 and is connected to the body 2 14.

A heat exchange discharge valve pipe 16 is connected to the top of the right end of the body 14. The temperature control regulator 17 installed at the left end of the body 14 is responsible for monitoring and adjusting the temperature of the medium inside the body 14. When it is detected that the temperature deviates from the set value, the temperature control regulator 17 will automatically adjust the heating or cooling mechanism to ensure that the heat exchange process is carried out under the most suitable temperature conditions.

[0038] according to Figure 3 As shown, the outer equally divided sleeve of the tube bundle is connected with a curved baffle 22, which is used to change the flow path of the shell-side fluid inside the body 1 and the body 2 14, so as to cause the fluid to bypass the tube bundle in a more complex and tortuous manner, thereby increasing the contact time and area between the fluid and the tube bundle. The curved baffle 22 is used to guide the fluid to flow along a non-straight path through its unique curved structure, thereby enhancing the turbulence of the fluid and forming a higher turbulent force, facilitating the mixing of fluid micro-clusters, promoting the continuous renewal of the thermal boundary layer, reducing thermal resistance, thereby accelerating heat transfer, and forcing the fluid to flow in a tortuous manner, so that its contact area with the surface of the tube bundle is greatly increased, thereby improving the overall heat exchange efficiency, reducing local hot spots, and making the heat flow more evenly distributed in the shell.

[0039] according to Figure 1 As shown, a PLC controller 3 is installed on the side wall surface of the liquid inlet control end 2. The PLC controller 3 is used to perform signal control connection on the overall device. The PLC controller 3 can be used to control the liquid inlet valve tube 4, the air inlet valve tube 5, the pneumatic regulator 1091, the micro electric guide rod 1094, the electromagnetic screw conveying guide rail 11, the temperature control regulator 17, the exchange filter 18, the dual-axis pneumatic gas rod 25 and the small ultrasonic generator 26 in the overall device.

[0040] The wiring diagram of the high-precision detection sensor, attachment detection sensor, PLC controller 3, pneumatic regulator 1091, micro electric guide rod 1094, temperature control regulator 17, exchange filter 18 and small ultrasonic generator 26 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring layout of the high-precision detection sensor, attachment detection sensor, PLC controller 3, pneumatic regulator 1091, micro electric guide rod 1094, temperature control regulator 17, exchange filter 18 and small ultrasonic generator 26 will no longer be explained in detail.

[0041] The method of use and working principle of the device are as follows: first, when the heat exchanger needs to be operated, the air inlet valve pipe 5 is opened to allow air or specific gas to enter the bottom of the body 1 through the high-precision detection sensor. The high-precision detection sensor monitors the gas flow and pressure during this process. Subsequently, the liquid inlet valve pipe 4 is opened, and the liquid is accurately measured and introduced into the body 1 under the monitoring of the high-precision detection sensor, and the attachment detection sensor is used to monitor the internal condition of the body 1. When contaminants are detected on the inner wall of the body 1, the small ultrasonic generator 26 is precisely positioned by the electromagnetic spiral conveying guide rail 11, and moves along a spiral trajectory along a specified position outside the body 1, so that the small ultrasonic generator 26 is started and emits ultrasonic vibrations, which effectively The attachments or fine particles on the wall of the body 1 are stripped off, and at the same time, the attachment detection sensor continuously monitors the cleaning effect and any abnormal conditions that may occur, such as excessive vibration or incomplete cleaning of the area, and with the cooperation of the decontamination discharge valve pipe 7, it is convenient to discharge the adhered dirt generated inside the body 1 and the body 2 14 at a regular time. After the gas enters the body 1 from the intake valve pipe 5, the sealing partition plate 23 inside the intake partition end 9 and the tube bundle bending connecting end 8 can make the airflow entering the body evenly distributed to avoid direct impact. The evenly distributed gas then enters the heat transfer channel 21 and is transported to the body 2 14 through the secondary heat exchange pipeline 20, further improving the heat exchange efficiency, and the PLC controller 3 sends a command to the dual-axis pneumatic The gas rod 25 drives the regulating valve plate 24 to move left and right in the heat transfer channel 21, thereby changing the cross-sectional area of ​​the heat transfer channel 21, finely adjusting the gas flow and flow rate, and forming dynamic regulation, which helps to maintain the ideal heat exchange efficiency and system stability, and further ensures the pressure regulation during the operation of the device body 1, and uses the circulation exchange pipe 19 to make the heat exchange materials inside the device body 1 and the device body 2 14 can selectively form a circulation exchange according to the heat exchange performance, and with the cooperation of the exchange filter 18, the impurities, pollutants or unnecessary components in the medium in the circulation exchange can be effectively removed, ensuring the quality of the circulating medium, cooperating with the fine adjustment of temperature and pressure to meet different exchange efficiencies, and at the same time using the left end of the device body 2 14 installed The temperature control regulator 17 is responsible for monitoring and adjusting the temperature of the medium inside the body 2 14. When it is detected that the temperature deviates from the set value, the temperature control regulator 17 will automatically adjust the heating or cooling mechanism to ensure that the heat exchange process is carried out under the most suitable temperature conditions. The connecting flange seal 15 ensures the sealing connectivity of the body 2 14 and is convenient for subsequent disassembly, maintenance and cleaning. The heat exchange discharge valve pipe 16 is the control pipeline used for guiding the discharge of the overall heat exchange. Then, with the cooperation of the built-in pressure detection sensor, the pneumatic regulator 1091 and the micro-electric guide rod 1094 first receive the pressure adjustment signal sent by the PLC controller 3. According to the signal instruction, the micro-electric guide rod 1094 is started and pushes the in-and-out pneumatic rod 1093 to advance.The pneumatic regulator 1091 synchronously regulates the gas flow and pressure entering the piston and entering and exiting the pneumatic rod 1093, so that the pneumatic rod 1093 can drive the piston rod 107 and the connecting end 106 to push the rack 1090 to slide on the top wall surface of the bracket plate 102, and according to the displacement of the rack 1090, the meshing formed by the multiple sets of pinions 109 and the rack 1090 and the rack 2 105 is used to make the rack 2 105 slide synchronously in the rack slide rail 104, thereby driving the memory metal blocking tube 108 to form a one-way sealing plug connection in the multiple sets of corresponding holes 27, so that in the heat exchange process, it can be controlled according to the control. The pressure and flow rate of the fluid flowing into the heat exchanger are controlled to form dynamic pressure regulation, thereby improving the service life of the overall operation. The setting of the curved baffle 22 guides the fluid to flow along a non-linear path through its unique curved structure, thereby enhancing the turbulence of the fluid and forming a higher turbulent force, facilitating the mixing of fluid micro-groups, promoting the continuous renewal of the thermal boundary layer, reducing thermal resistance, thereby accelerating heat transfer, and forcing the fluid to flow in a tortuous manner, thereby greatly increasing its contact area with the surface of the tube bundle, improving the overall heat exchange efficiency, reducing local hot spots, and making the heat flow more evenly distributed in the shell.
