Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower filler cleaning, in particular to a scale cleaning device for thermal power cooling tower fillers. Background Technique

[0002] The main function of a thermal power cooling tower is to help a thermal power plant cool down and cool the circulating water through the heat exchange between water and air. When using the thermal power cooling tower to cool the circulating water, its internal filler components are usually used to filter the circulating water and extend the cooling time of the circulating water. Due to the filtering characteristics of the filtering filler, a large amount of impurities will accumulate inside it. Therefore, a cleaning device needs to be used to regularly clean the internal scale. As shown in a scale removal device for cooling tower fillers disclosed on the Chinese Patent Network (publication number CN219869285U), when such a device is used to clean the filler, based on the combination of a cylinder and a cleaning frame, the filler is driven to reciprocate. While it is operating, the combination of a flushing component and a brush component is used to flush and brush-clean the filler.

[0003] However, for the above-mentioned disclosed patents and the existing market's scale removal devices for cooling tower fillers, there are still some deficiencies: The existing cleaning method that uses a combination of a brush roller and flushing to clean the filler can only clean the surface part of the filler, and cannot comprehensively clean the scale in the core of the filler, resulting in relatively low cleaning efficiency. Therefore, technical personnel in this field have provided a scale cleaning device for thermal power cooling tower fillers to solve the problems raised in the above background technique. Content of the Utility Model
