Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning tool for a tubular cooler in a hydropower station. Background Art
[0002] Shell-and-tube coolers are a commonly used type of cooler. They offer advantages such as low manufacturing difficulty, simple structure, and ease of maintenance, making them widely used for cooling various gases and liquids. However, due to the roughness of the inner surface of the heat exchange tubes, shell-and-tube coolers are prone to scaling and clogging, which reduces the actual heat exchange efficiency and increases the cooler's pressure drop. Furthermore, since the cooling medium for shell-and-tube coolers is generally industrial water or tap water, the blocked heat exchange tubes are unable to flow. The chloride ions and sulfate ions contained in the cooling water exponentially increase corrosion of the cooler tubes, reducing their service life. Furthermore, during the flood season of hydropower stations, the sediment content in the river water is often high, and sediment often adheres to the cooler tube walls, seriously affecting their cooling efficiency. Therefore, regular maintenance and cleaning of the coolers are necessary.
[0003] At present, the cleaning methods for the heat exchange tubes of shell and tube coolers during maintenance work usually use strong acid chemical cleaning, sponge ball cleaning tools or high-pressure water guns and other cleaning tools, which are difficult to clean and have poor cleaning effects. Some also use stainless steel rods to remove scale and foreign matter on the tube wall, which is inefficient and has poor cleaning effects, is easy to damage the tube wall, and is time-consuming and labor-intensive.
