Description

Technical Field

[0001] This utility model belongs to the field of heat exchange, specifically relating to AI intelligent control heat exchange units. Background Technology

[0002] Plate heat exchangers are commonly used in the heat exchange field, often for waste heat recovery from exhaust gases and wastewater. Because the operation of heat exchangers requires corresponding piping and monitoring instruments, after purchasing a heat exchanger, the manufacturer needs to provide on-site adjustments to the piping and testing instruments, which affects efficiency and increases labor costs. To improve ease of use, manufacturers offer heat exchanger assemblies, where the necessary piping and testing instruments are assembled at the manufacturer's location and sold as a complete unit. However, selling the entire unit requires controlling its dimensions for transportation, inevitably requiring multiple bends and loops in the piping. This makes pressure changes within the piping more complex than with straight pipe connections during heat exchange, necessitating more pressure gauges and increasing the frequency of pump and valve adjustments by the user. This not only increases workload but also raises the error rate. Furthermore, the bends in the pipes make it easier for impurities to accumulate at the bends, thus increasing the impact of impurities on the flow rate of the heat exchange medium and heat exchange efficiency. Utility Model Content

[0003] To address the aforementioned issues, this application proposes an AI-controlled heat exchanger unit. By setting up control components to monitor and control the pressure of various pipelines within the heat exchanger unit, the accuracy of pressure control within the pipelines during the heat exchange process is improved, enabling automatic water replenishment and pressure regulation, as well as automatic circulation control. Simultaneously, a filtration device is included, which, in conjunction with the slag discharge port, removes impurities. The control components also monitor the pressure at both the filtration device and the slag discharge port, automatically monitoring slag discharge.

[0004] The technical solution is: an AI-controlled heat exchanger unit, including a heat exchange mechanism, a primary side pipe assembly, a secondary side pipe assembly, a circulation mechanism, and a water replenishment mechanism;

[0005] Both the primary and secondary side pipe groups are connected to the heat exchange mechanism; the secondary side pipe group is connected to the circulation mechanism; the circulation mechanism is connected to the water supply mechanism.

[0006] Both the circulation mechanism and the primary side pipe assembly are equipped with filtration devices; both the filtration devices and the circulation mechanism are equipped with pressure detection devices.

[0007] The circulation mechanism, water replenishment mechanism, filtration device, and pressure detection device are all connected to the control components.

[0008] Furthermore, the circulation mechanism includes a conveying pipe, a circulation pump, and a circulation pipe; the secondary side pipe assembly includes a secondary side inlet pipe and a secondary side outlet pipe; the conveying pipe and the secondary side inlet pipe are connected, the circulation pipe is located between the secondary side inlet pipe and the secondary side outlet pipe, the circulation pump is located in the conveying pipe, and both the secondary side outlet pipe and the circulation pipe are equipped with shut-off valves.

[0009] The medium to be heated enters the secondary side inlet pipe through the conveying channel and then enters the heat exchanger, which is a plate heat exchanger; the medium to be heated is driven by the circulating pump to circulate repeatedly in the heat exchanger and is heated by the high temperature medium.

[0010] Furthermore, the primary side pipe assembly includes a primary side inlet pipe; the filter device is respectively installed at the inlet end of the conveying pipeline and the primary side inlet pipe, and pressure detection devices are installed upstream and downstream of the filter device to detect the pressure of the filter device.

[0011] Furthermore, the primary side tube assembly also includes a primary side outlet tube; both the primary side outlet tube and the secondary side outlet tube are equipped with pressure detection devices; the pressure detection devices are used to monitor the pressure discharged after the two media exchange heat and compare it with the pressure when it enters, so as to reflect the scaling situation in the heat exchanger.

[0012] Furthermore, the water replenishment mechanism includes a water replenishment pipe, a water replenishment pump, and a check valve; the water replenishment pump is connected to the water replenishment pipe, the water replenishment pipe is connected to the circulation pipe, and the water replenishment pipe is connected upstream of the filtration device; so that the water replenishment mechanism filters the water replenished in the delivery pipe through the filtration device.

[0013] When the pressure detection device detects insufficient pressure, the control component controls the water replenishment mechanism to replenish the heated medium to increase the pressure in the delivery pipeline.

[0014] Furthermore, the filtration device includes an inlet, an outlet, and a filter end; the inlet and the filter end are connected by a bend, with the filter end pointing vertically downwards; the outlet is connected to the side opposite to the filter end and the inlet; guide lines are provided on the inner wall from the inlet to the filter end; the filter end is provided with a filter cartridge; a solenoid valve port is provided at the port of the filter end, and the solenoid valve port is connected to the control component.

[0015] During filtration, the medium flows into the filter end from the inlet, and then enters the filter cartridge for filtration along the guide line before flowing out from the outlet. Impurities settle and accumulate inside the filter cartridge. When too many impurities accumulate, they will clog the outlet and increase the pressure. At this time, the control component detects and automatically opens the solenoid valve at the filter end, using water flow to remove the settled impurities.

[0016] Furthermore, an air jet device is connected through the sidewall of the filter end, and the air jet device has multiple air jet ports along the filter end.

[0017] When too many impurities accumulate and water flow alone is insufficient to remove them, the air jet device can be turned on to spray air onto the filter screen to remove the impurities. After the impurities are removed, the control component closes the filter end.

[0018] Furthermore, the bottom of the filter end is provided with a sliding track along the edge of the filter cartridge, and a slider is provided at the bottom of the filter cartridge, with the slider connected to the sliding track;

[0019] The jet device is positioned facing the side wall of the filter end, and a jet nozzle is located on the sliding track. The jet nozzle sprays air to push the slider to slide.

[0020] When sewage discharge is required, the jet device is turned on. At this time, the jet device drives the slider to slide and rotate the filter cartridge. At the same time, it also drives the liquid in the filter end to rotate, thereby forming a turbulent vortex, which accelerates the sewage discharge efficiency. At the same time, the high-speed rotating vortex will flush the side wall of the filter end, causing the impurities deposited on the filter end wall to fall off and enhance the sewage discharge effect.

[0021] Alternatively, the exhaust vents can be evenly distributed along the sidewall of the filter end.

[0022] Furthermore, temperature detection devices are installed in the conveying pipeline, primary side inlet pipe, primary side outlet pipe, and secondary side outlet pipe.

[0023] Furthermore, the connection between the conveying pipeline and the secondary side inlet pipe is a U-shaped pipe. The bottom end of the U-shaped pipe is provided with a gradually concave sedimentation tank, and the bottom end of the sedimentation tank is provided with a slag discharge port. An electric control valve is provided at the slag discharge port, and the electric control valve is also connected to the control component. When the pressure of the pressure detector at the secondary side inlet pipe increases, it indicates that too many impurities have been deposited in the sedimentation tank. The control component controls the slag discharge port to open and discharge the impurities.

[0024] A filter device can be installed instead of a slag discharge port; both the slag discharge port and the filter end are connected to a sewage pipe.

[0025] The slag discharge port is detachably equipped with an adsorption filter element, which is filled with pretreated activated carbon beads to enhance the adsorption of impurities. The adsorption filter element is detachable and can be manually replaced periodically.

[0026] Furthermore, the filtration device, water replenishment mechanism, circulation mechanism, and pressure detection device are all connected to control components; the control components are connected to an AI module, and by combining the data transmitted by the pressure detection device and temperature detection device, the AI ​​model can dynamically adjust its flow rate, temperature, and pressure; compared with existing controllers, its control is more precise; the AI ​​module based on the analysis of temperature difference and pressure drop data can provide early warning of scaling, and existing AI module technologies can be used here.

[0027] When the upstream pressure detection device of the filter at the inlet of the pipeline shows an increase in pressure and the downstream pressure shows a decrease in pressure, the control component needs to open the filter end of the filter to discharge sewage; when both pressures decrease, the water replenishment mechanism is opened to replenish water.

[0028] When the pressure of the pressure detection device in the primary side inlet pipe increases and the pressure of the primary side outlet decreases, the pressure detection device needs to open the filter device of the primary side inlet pipe to drain the sewage.

[0029] Furthermore, the pressure detection device includes a pressure gauge and a pressure transmitter; the temperature detection device includes a bimetallic thermometer and a temperature transmitter.

[0030] The beneficial effects of this utility model are as follows:

[0031] (1) The heat exchanger unit of this utility model can automatically adjust pressure, automatically drain sewage, and automatically circulate. By using pressure detection device and control components together, the manual requirements are reduced, automatic regulation is realized, and the data of the heat exchange process is more accurately controlled and the heat exchange efficiency is higher.

[0032] (2) The filter device of this utility model drives the filter cylinder to rotate through the jet device, which makes the sewage discharge efficiency faster and improves the sewage discharge effect, making the sewage discharge more thorough.

[0033] (3) The heat exchange unit of this utility model is equipped with a filter device for the structure of the heat exchange unit and a slag discharge port is set in the area where impurities are easy to accumulate. The filter device and the slag discharge port work together to reduce impurities in the pipeline. The control component works with the pressure detection device to automatically discharge sewage, which reduces the impact of impurities on heat exchange efficiency during the heat exchange process and extends the scaling cycle of the heat exchange mechanism.

[0051] The circulation mechanism 4, water replenishment mechanism 5, filtration device 6, and pressure detection device 7 are all connected to the control components.

[0052] In one specific embodiment, such as Figure 1 As shown, the circulation mechanism 4 includes a conveying pipe 41, a circulation pump 42, and a circulation pipe 43; the secondary side pipe group 3 includes a secondary side inlet pipe 31 and a secondary side outlet pipe 32; the conveying pipe 41 and the secondary side inlet pipe 31 are connected, the circulation pipe 43 is located between the secondary side inlet pipe 31 and the secondary side outlet pipe 32, the circulation pump 42 is located in the conveying pipe 41, and both the secondary side outlet pipe 32 and the circulation pipe 43 are equipped with shut-off valves.

[0053] The medium to be heated enters the secondary side inlet pipe 31 through the conveying channel and then enters the heat exchanger, which is a plate heat exchanger; the medium to be heated is driven by the circulating pump 42 to circulate repeatedly in the heat exchanger and be heated by the high temperature medium.

[0054] In one specific embodiment, such as Figure 2 As shown, the primary side pipe assembly 2 includes a primary side inlet pipe 21; the filter device 6 is respectively installed at the inlet end of the conveying pipeline 41 and the primary side inlet pipe 21, and pressure detection devices 7 are installed upstream and downstream of the filter device 6, and the pressure detection devices 7 perform pressure detection on the filter device 6.

[0055] In one specific embodiment, such as Figure 1-3 As shown, the primary side pipe group 2 also includes a primary side outlet pipe 22; both the primary side outlet pipe 22 and the secondary side outlet pipe 32 are equipped with pressure detection devices 7; the pressure detection devices 7 are used to monitor the pressure discharged after the two media exchange heat and compare it with the pressure when it enters, so as to reflect the scaling situation in the heat exchanger.

[0056] In one specific embodiment, such as Figure 1 As shown, the water replenishment mechanism 5 includes a water replenishment pipe, a water replenishment pump 52, and a check valve 53; the water replenishment pump 52 is connected to the water replenishment pipe, the water replenishment pipe is connected to the circulation pipe 43, and the water replenishment pipe is connected upstream of the filter device 6; so that the water replenishment mechanism 5 filters the water replenished in the delivery pipe 41 through the filter device 6.

[0057] When the pressure detection device 7 detects insufficient pressure, the control component controls the water replenishment mechanism 5 to replenish the heated medium to increase the pressure in the delivery pipeline 41.

[0059] During filtration, the medium flows into the filter end 63 from the inlet 61, and then enters the filter cartridge 631 for filtration through the guide line 632, before flowing out from the outlet. Impurities settle and accumulate inside the filter cartridge 631. When too many impurities accumulate, they will block the outlet 62, increasing the pressure. At this time, the electrically controlled valve 635 of the filter end 63 opens, using the water flow to remove the settled impurities.

[0060] In one specific embodiment, such as Figure 4-5 As shown, an air jet device 64 is connected through the side wall of the filter end 63, and the air jet device 64 is provided with a plurality of air jet ports 641 evenly distributed along the filter end 63.

[0061] When too many impurities accumulate and water flow alone is insufficient to flush them out, the jet device 64 can be turned on to spray air onto the filter screen to remove the impurities. After the impurities are removed, the control component closes the electrically controlled valve port 635 at the filter end 63.

[0062] In another specific embodiment, such as Figure 6-7 As shown, the bottom of the filter end 63 has a sliding track 633 arranged along the edge of the filter cylinder 631, and a slider 634 is arranged at the bottom of the filter cylinder 631.

[0064] When sewage discharge is required, the jet device 64 is turned on. At this time, the jet device 64 drives the slider 634 to slide, causing the filter cartridge 631 to rotate. At the same time, it also drives the liquid in the filter end 63 to rotate, thereby forming a turbulent vortex, which accelerates the sewage discharge efficiency. At the same time, the high-speed rotating vortex will flush the side wall of the filter end 63, causing the impurities deposited on the wall of the filter end 63 to fall off, thus enhancing the sewage discharge effect.

When the pressure of the pressure detector at the secondary side inlet pipe increases, it indicates that too many impurities have been deposited at the sedimentation tank. The control component controls the slag discharge port 412 to open and discharge the impurities.

[0069] When the pressure of the pressure detection device 7 in the primary side inlet pipe 21 increases and the pressure of the primary side outlet decreases, the pressure detection device 7 needs to open the filter device 6 in the primary side inlet pipe 21 to drain the sewage.

[0070] In one specific embodiment, the pressure detection device 7 includes a pressure gauge and a pressure transmitter; the temperature detection device 8 includes a bimetallic thermometer and a temperature transmitter.
