Description

Technical Field

[0001] This invention relates to the field of PTFE heat exchanger technology, specifically to a corrosion-resistant and high-efficiency PTFE heat exchanger. Background Technology

[0002] PTFE heat exchangers use polytetrafluoroethylene (PTFE) as the heat transfer component. Benefiting from their thinner tube walls, PTFE heat exchangers are more efficient in heat exchange and possess excellent corrosion resistance, making them widely used in heat exchange applications involving hazardous chemical media. Their main principle is to achieve cooling of the medium by exchanging heat between cooling water inside the PTFE tube and the hot medium outside the tube. While current corrosion-resistant and high-efficiency PTFE heat exchangers have strong corrosion resistance, long-term use can still lead to cracks in the PTFE tubes due to factors such as temperature variations. Thin inner linings are not suitable for this purpose, resulting in poor protection. Traditional pressure detection methods are inaccurate when cracks are small, as pressure fluctuations are minimal. They are also not suitable for using inner linings to amplify pressure differences. Furthermore, during this process, for example, some acidic media may continuously react with the cooling water, causing changes in the water quality throughout the cooling pipeline, posing safety hazards.

[0003] Therefore, we propose a corrosion-resistant and high-efficiency PTFE heat exchanger. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention employs PTFE tubing in conjunction with an internal rubber tube, which enhances the safety of PTFE heat exchange, preventing chemical reactions caused by leaks and reducing costs due to equipment corrosion. Simultaneously, the rubber tube, when leaking PTFE, indents inward, increasing resistance and allowing for timely pressure detection with a pressure switch. This inward indentation of the rubber tube increases water flow resistance, ensuring that even small cracks in the PTFE tube gradually indent with accumulated leakage, facilitating pressure switch detection. Furthermore, the pressure switch automatically controls the inlet water control pipe and heat medium conduit to stop water and heat medium intake, while simultaneously opening the pressure relief pipe to assist in the discharge of corrosive heat media, reducing corrosion of the rubber tube and increasing equipment operational safety.

[0017] The use of a flow retainer allows for automatic control, enabling continuous cooling water circulation even when the inlet control pipe stops supplying cooling water. This makes it more suitable for multi-stage cooling circulation pipelines. The use of a pressurization auxiliary component further promotes the expansion of rubber hoses that have been dented due to leakage by introducing high-pressure gas, helping to expel corrosive heat media that have infiltrated between the rubber hose and the PTFE hose, thus further reducing the corrosion of the rubber hose by corrosive heat media.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 9 As shown:

[0030] This invention provides a technical solution: a corrosion-resistant, high-efficiency PTFE heat exchanger, comprising a heat exchange shell 1, a PTFE heat exchange device 2 installed inside the heat exchange shell 1 for preventing chemical reactions; a water inlet control component 3 and a drain control component 4 are installed on the heat exchange shell 1; passage retaining components 5 are installed on the water inlet control component 3 and the drain control component 4; a pressurizing auxiliary component 6 is installed on the heat exchange shell 1; the heat exchange shell 1 includes a flow pipe 101 and end caps 1011, with flanges at both ends of the flow pipe 101, and two end caps 1011, each with a flange; the flanges at both ends of the flow pipe 101 are fixedly mounted to the flanges of the two end caps 1011 by bolts; the inner side of the flow pipe 101 is coated with PTFE.

[0031] The heat exchange housing 1 includes: a heat medium conduit 102, a first solenoid valve 103, a heat medium discharge pipe 104, a pressure relief pipe 105, and a second solenoid valve 106. The heat medium conduit 102 is fixedly installed on a flow pipe 101; a flange is provided on the flow pipe 101; the first solenoid valve 103 is installed on the heat medium conduit 102; the heat medium discharge pipe 104 is fixedly installed on the flow pipe 101, and a flange is provided at the end of the heat medium discharge pipe 104; a pressure relief pipe 105 is fixedly installed at the bottom of the flow pipe 101, and a flange is provided at the end of the pressure relief pipe 105; the second solenoid valve 106 is installed on the pressure relief pipe 105; the pressure relief pipe 105 is used for discharge. An airflow pipe 101; a pressure relief pipe 105 connected to an external waste liquid storage tank; a PTFE heat exchange device 2 includes: heat exchange baffles 201 and PTFE tubes 202. Two heat exchange baffles 201 are fixedly installed inside the airflow pipe 101, and three turns of PTFE tubes 202 are fixedly installed on each of the two heat exchange baffles 201. The PTFE tubes 202 are used for heat exchange of the heat medium. Cooling water flows outside the two heat exchange baffles 201, and the heat medium flows between the two heat exchange baffles 201. The pressure of the heat medium outside the PTFE tubes 202 is greater than the pressure of the cooling water inside the PTFE tubes 202. The PTFE heat exchange device 2 also includes: a rubber ring 2021 and a rubber tube 2022. 2. Rubber rings 2021 are fixedly installed at both ends, and a rubber tube 2022 is fixedly installed between the two rubber rings 2021, with the rubber tube 2022 located inside the PTFE tube 202; the rubber tube 2022 is used for the flow of cooling water; the rubber tube 2022 and the PTFE tube 202 are separate; the water inlet control component 3 includes: a water inlet control pipe 301, a third solenoid valve 302, a pressure switch 303, and a relay 304. The water inlet control pipe 301 is fixedly installed on the end cap 1011 near the first solenoid valve 103; the water inlet control pipe 301 is provided with a flange; the LU-S541 type pressure switch 303 can be used; the water inlet control pipe A third solenoid valve 302 is fixedly installed on 301; a pressure switch 303 is fixedly installed on the water inlet control pipe 301, and the detection end of the pressure switch 303 is located inside the water inlet control pipe 301; a relay 304 is installed on the water inlet control pipe 301. The use of a PTFE tube 202 in conjunction with an internally installed rubber tube 2022 can improve the heat exchange safety of the PTFE tube 202 and avoid leakage that could cause a chemical reaction of the chemical heat medium, thus preventing safety hazards. At the same time, if the PTFE tube 202 cracks, the chemical heat medium will directly enter the drain pipe 401, causing the entire cooling water pipeline to be corroded by the chemical medium, increasing the cost losses caused by equipment corrosion.Simultaneously, by utilizing the rubber hose 2022, when the PTFE hose 202 leaks, the greater pressure of the heat medium causes it to penetrate between the PTFE hose 202 and the rubber hose 2022, causing the rubber hose 2022 to indent inward. As the rubber hose 2022 indents, its resistance increases. Combined with the pressure switch 303, pressure changes can be detected promptly. By utilizing the inward indentation of the rubber hose 2022 to increase water flow resistance, even if the crack in the PTFE hose 202 is small, the accumulated leakage will cause the rubber hose 2022 to gradually indent, facilitating detection by the pressure switch 303. Furthermore, the pressure detection method using the pressure switch 303 can automatically control the inlet control pipe 301. The hot medium conduit 102 is shut off from both water and hot medium intake. Simultaneously, the pressure relief pipe 105 is opened to assist in the discharge of corrosive hot medium, promptly emptying the hot medium and reducing its corrosive effect on the rubber hose 2022. This further enhances equipment operational safety. During normal heat exchange, the flange at the end of the water inlet control pipe 301 is connected to the cooling water source pipe, allowing continuous water intake. The cooling water flows through the rubber hose 2022 and is discharged from the drain pipe 401, entering the subsequent cooling or recovery section. During this process, the flange at the top of the hot medium conduit 102 is connected to the hot medium pipeline, continuously discharging hot medium. After cooling and heat exchange through the PTFE tube 202, the hot medium is discharged from the hot medium discharge pipe 104.

[0032] The drainage control component 4 includes a drain pipe 401 and a fourth solenoid valve 402. The drain pipe 401 is fixedly installed on another end cap 1011. A flange is provided on the drain pipe 401. The fourth solenoid valve 402 is installed on the drain pipe 401. The passage retaining component 5 includes a guide pipe 501. One end of the guide pipe 501 is fixedly installed on the inlet control pipe 301. The other end of the guide pipe 501 is fixedly installed on the drain pipe 401. The guide pipe 501 connects the drain pipe 401 and the inlet control pipe 301. The passage retaining component 5 also includes a solenoid valve 502. The solenoid valve 502 is fixedly installed on the guide pipe 501. By using the passage retaining component 5, when the inlet control pipe 301 stops cooling water intake, the bypass auxiliary flow can be used to keep the cooling water continuously circulating. This is more suitable for multi-stage cooling circulation pipelines and ensures normal cooling.

[0033] In Example 2, based on Example 1, the pressurizing auxiliary component 6 includes: a pressurizing connecting pipe 601 and a pressurizing solenoid valve 6011. The pressurizing connecting pipe 601 is fixedly installed at the bottom of the flow pipe 101 and is located outside the heat exchange baffle 201. The pressurizing solenoid valve 6011 is installed on the pressurizing connecting pipe 601. The pressure switch 303 is electrically connected to the relay 304, and the relay 304 is electrically connected to the first solenoid valve 103, the second solenoid valve 106, the third solenoid valve 302, the fourth solenoid valve 402, the conduction solenoid valve 502, and the pressurizing solenoid valve 6011. The pressurizing auxiliary component 6 also includes: a high-pressure gas cylinder 602, which is fixedly installed at the bottom of the pressurizing connecting pipe 601. The high-pressure gas cylinder 602 is used to pressurize the inside of the rubber tube 2022. The pressurization auxiliary component 6 can further promote the expansion of the rubber tube 2022, which has been dented due to leakage, by introducing high-pressure gas into the rubber tube 2022. This helps to expel the corrosive heat medium that has invaded between the rubber tube 2022 and the PTFE tube 202, further reducing the corrosion of the rubber tube 2022 by the corrosive heat medium and reducing the risk of subsequent chemical reactions. The structure is simple to control. After the pressure switch 303 detects an abnormal pressure, it can control the pressurization solenoid valve 6011 to open, and use high-pressure gas to directly fill the inside of the rubber tube 2022. At this time, the rubber tube 2022 expands, which can help to expel the corrosive heat medium that has invaded between the rubber tube 2022 and the PTFE tube 202 from the damaged part of the PTFE tube 202, reducing the residue of the corrosive medium.

[0034] The working principle of this embodiment is as follows: First, during normal heat exchange, the flange at the end of the water inlet control pipe 301 is connected to the cooling water source pipe, and water is continuously supplied. The cooling water flows through the rubber tube 2022 and is discharged from the drain pipe 401, entering the subsequent cooling or recovery section. During the process, the flange at the top of the heat medium conduit 102 is connected to the heat medium pipe, and heat medium is continuously discharged. After cooling and heat exchange through the PTFE tube 202, it is discharged from the heat medium discharge pipe 104. During the heat exchange process, if there is a leak in the PTFE tube 202, the heat medium pressure will cause it to infiltrate between the PTFE tube 202 and the rubber tube 2022. 022 will not completely corrode and break in a short time; as the amount of hot medium intrusion increases, it can cause the rubber tube 2022 to concave inward, affecting the flow of cooling water and increasing resistance. At this time, the cooling water pressure increases. After the pressure switch 303 detects the increase in water pressure, it controls the relay 304 to turn on the power, controlling the third solenoid valve 302 and the fourth solenoid valve 402 to close, stopping the cooling water from entering the rubber tube 2022 and also avoiding contamination by corrosive hot medium; at the same time, the first solenoid valve 103 will also close, suspending the entry of hot medium, and the second solenoid valve 106 will be controlled to open, assisting in emptying the hot medium in the flow pipe 101;

[0035] When pressure switch 303 detects an abnormal pressure and controls the third solenoid valve 302 to close via relay 304, it can simultaneously control the opening of solenoid valve 502, allowing cooling water to be circulated through drain pipe 401 via connecting pipe 501 without affecting the overall pipeline flow. Simultaneously, when pressure switch 303 detects an abnormal pressure and controls the second solenoid valve 106 to open via relay 304 to release pressure and discharge corrosive heat medium, it can simultaneously control the opening of pressurizing solenoid valve 6011. With the heat exchange baffle 201 providing isolation, the high-pressure gas inside high-pressure cylinder 602 directly fills the inside of rubber tube 2022. At this time, rubber tube 2022 expands, which helps to discharge the corrosive heat medium that has infiltrated between rubber tube 2022 and PTFE tube 202 from the damaged part of PTFE tube 202, reducing the residue of corrosive medium.
