Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger cleaning, and in particular to a wound tube heat exchanger cleaning device and a cleaning process thereof. Background Art

[0002] The wound-tube heat exchanger is a highly efficient heat exchange device with advantages such as compact structure, high heat transfer efficiency, and strong adaptability. It is widely used in many industries such as petroleum, chemical industry, electric power, and metallurgy. It achieves heat exchange between hot and cold fluids by winding the heat exchange tubes around a central tube in a certain pattern, forming a complex tube bundle structure.

[0003] However, over long-term use, scale inevitably forms inside wound-tube heat exchangers. This scale primarily originates from impurities in the fluid, chemical reaction products, and microorganisms. These deposits adhere to the inner walls of the heat exchange tubes, gradually forming a thick layer. The presence of scale can have a serious negative impact on the heat exchanger's performance. The thermal conductivity of scale is much lower than that of metal heat exchange tubes, creating an additional layer of thermal resistance between the hot and cold fluids, hindering heat transfer and significantly reducing the heat exchanger's efficiency. Maintaining the same heat transfer efficiency requires more energy, increasing operating costs. Scale accumulation reduces the inner diameter of the heat exchange tubes, increasing resistance to fluid flow. This not only requires more power to propel the fluid, but can also lead to insufficient flow, disrupting the normal operation of the entire process. Scale can cause localized corrosion and stress concentration, accelerating tube damage and shortening the equipment's service life. Frequent equipment repairs and replacements not only increase a company's investment costs but also disrupt production, impacting profitability.

[0004] Currently, there are two main cleaning methods for wound-tube heat exchangers: chemical cleaning and physical cleaning. Chemical cleaning involves injecting chemical cleaning agents into the heat exchanger, using chemical reactions to dissolve dirt. However, this method has some drawbacks. For example, chemical cleaning agents may corrode the heat exchange tubes, shortening the lifespan of the equipment. The waste liquid after cleaning contains a large amount of chemical substances, which can pollute the environment if improperly handled. Furthermore, chemical cleaning is not ideal for some stubborn scale layers. Physical cleaning is the second method, with common methods including high-pressure water jet cleaning and mechanical scraping. While high-pressure water jet cleaning can remove dirt to a certain extent, it is difficult to ensure comprehensive and thorough cleaning of the complex tube bundle structure inside a wound-tube heat exchanger. Mechanical scraping cleaning requires disassembly of the equipment, which is cumbersome and labor-intensive, and can easily damage the heat exchange tubes.

[0005] Therefore, in response to the above problems, in order to effectively solve the shortcomings of existing cleaning methods, improve the cleaning quality and efficiency of heat exchangers, and ensure the long-term stable operation of equipment, this scheme proposes a wound tube heat exchanger cleaning equipment and its cleaning process. Summary of the Invention

[0006] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a wound tube heat exchanger cleaning device and a cleaning process thereof, wherein multiple high-pressure nozzles and rotating parts in the decontamination device work in coordination.

When the positioning joint blocks the pipe mouth, the water column ejected from the high-pressure nozzle generates reverse thrust, pushing the decontamination device into the pipe; at the same time, the servo motor is started, and the active guide wheel and the driven guide wheel rotate, and the friction force is used to extend the high-pressure hose into the pipe, realizing the automatic advancement of the cleaning process and reducing manual operation.

[0018] According to the present invention, a wound tube heat exchanger cleaning process is provided, comprising the following steps:

[0019] Step 1: Install the decontamination device. Connect the high-pressure hose to the connection socket in the decontamination device through the quick connector to ensure that the cleaning water inside the high-pressure hose can be smoothly connected to the decontamination device.

[0020] Step 2: Connect the transmission device and install the high-pressure hose inside the transmission device. When installing, first pass the high-pressure hose through the positioning joint and the inside of the guide sleeve, and pass it between the driving guide wheel and the driven guide wheel. Use the pressure exerted by the reaction spring to make the driven guide wheel press the high-pressure hose tightly;

[0021] Step 3: Connect the water pump. Connect the other end of the high-pressure hose to the output end of the high-pressure water pump, and connect the input end of the high-pressure water pump to the water tank through a water pipe.

[0022] Step 4: water test. Start the high-pressure water pump to pump out water from the water tank and transport it to the decontamination device through the high-pressure hose. At this time, the high-pressure water flows through the central axis guide tube and is respectively ejected from the inside of the high-pressure nozzle 1, high-pressure nozzle 2, high-pressure nozzle 3, and high-pressure nozzle 4 through the fixed disk 1, fixed disk 2, and fixed disk 3. At this time, the guide blade 2 in the brush wheel 1 is subjected to the high-pressure water column ejected by the high-pressure nozzle 3, so that the brush wheel 1 rotates counterclockwise, and the guide blade 1 in the brush wheel 2 is subjected to the high-pressure water column ejected by the high-pressure nozzle 2, so that the brush wheel 2 rotates clockwise. The rotating cone head is subjected to the high-pressure water column ejected by the high-pressure nozzle 1 and the reverse thrust inclined plane, so that the rotating cone head rotates counterclockwise;

[0023] Step 5: Install and use the device. Insert the decontamination device into the pipe of the spiral wound heat exchanger and connect the positioning joint to the pipe mouth. Start the high-pressure water pump. At this time, the decontamination device works, using the high-pressure water flow to drive the brush wheel 1 and brush wheel 2 to rotate respectively, brushing the dirt on the pipe wall. The high-pressure water flow drives the rotating cone head to rotate, so that the front end can crush the harder dirt in the pipe. Use the positioning joint to block the pipe mouth of the spiral wound heat exchanger, so that the water column ejected from the high-pressure nozzle has a reverse thrust, which promotes the decontamination device to move into the pipe. In addition, a drainage hole is provided at the positioning joint to effectively drain excess water, avoid pipe expansion, and play a role in pressure relief.

[0024] Start the servo motor and control the motor speed to make the high-pressure hose rotate through the active guide wheel and the driven guide wheel. The friction force generated by the contact with the pipe wall of the high-pressure hose makes the high-pressure hose extend into the pipeline of the spiral tube heat exchanger.

[0025] Compared to existing technologies, the present invention's wound-tube heat exchanger cleaning equipment and cleaning process utilizes multiple high-pressure nozzles and rotating components within the decontamination device. Brush wheels 1 and 2 rotate clockwise and counterclockwise, respectively, under the influence of the high-pressure water flow, comprehensively removing dirt from the tube walls. The rotating cone head rotates counterclockwise under the pressure of the high-pressure water flow, and its outer surface scraping teeth break up hard dirt within the tube, significantly improving cleaning efficiency and quality.

[0026] Compared to existing technologies, the present invention's spiral wound heat exchanger cleaning equipment and process utilizes a reverse thrust mechanism when the locating joint blocks the pipe opening, ejecting water jets from the high-pressure nozzle. This thrust propels the decontamination device into the pipe. Simultaneously, the servo motor activates, rotating the active and passive guide pulleys, and utilizing friction to extend the high-pressure hose into the pipe, thus automatically advancing the cleaning process and reducing manual labor. Drain holes are provided on the outer surface of the locating joint to effectively drain excess water, preventing expansion of the pipe due to excessive water pressure. This provides pressure relief and protects the equipment from operating safely. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the decontamination device works, and uses the high-pressure water flow to drive the brush wheel 1 (12) and the brush wheel 2 (14) to rotate respectively to brush away the dirt on the pipe wall. Use the high-pressure water flow to drive the rotating cone head (16) to rotate so that it can crush the harder dirt in the pipe at the front end. Use the positioning joint (7) to block the pipe mouth of the wound tube heat exchanger so that the water column ejected by the high-pressure nozzle 4 (25) has a reverse thrust, which promotes the decontamination device to move into the pipe. A drainage hole (8) is provided at the positioning joint (7) to effectively discharge excess water, avoid pipe expansion, and play a role in pressure relief. The servo motor (4) is started and the rotation speed of the motor is controlled so that the high-pressure hose (9) rotates through the active guide wheel (20) and the driven guide wheel (17), and the friction force generated by the contact with the wall of the high-pressure hose (9) causes the high-pressure hose (9) to extend into the pipeline of the wound tube heat exchanger.
