Description

High-Rise Building Pipe Cleaning System Equipped with Vibration-Reducing Eccentric Nozzle The present invention relates to a cleaning method and system for eccentric nozzle pipes in high-rise buildings equipped with a vibration reduction function. Specifically, the invention relates to a cleaning system capable of effectively removing scale, foreign substances, and corrosion products accumulated inside pipes in high-rise buildings, while simultaneously mitigating vibrations in the winding section to improve the stability and durability of the device. Over the long term, pipes in high-rise buildings accumulate scale, foreign matter, and corrosion products, leading to reduced flow rates and weakened durability. This problem not only degrades pipe performance but also has the potential to result in serious damage, such as pipe rupture, in the long run. In particular, high-rise buildings present significant challenges in maintenance and management due to their complex, long pipe structures and difficult access. Therefore, there is a need to develop effective cleaning methods and systems suitable for high-rise building piping. Conventional pipe cleaning methods include chemical cleaning, mechanical cleaning, and high-pressure cleaning, but each method has specific limitations. Chemical cleaning offers excellent cleaning efficacy but poses environmental risks due to detergent residues and the potential to damage pipe materials. Mechanical cleaning is suitable for physical removal but has limited accessibility in long pipes or curved structures. High-pressure cleaning utilizes powerful jets, but the high pressure poses a risk of pipe damage, and its cleaning effectiveness may be limited to specific areas. To overcome these limitations, cleaning methods utilizing pulsed jet nozzles are gaining attention. Eccentric nozzles spray pulsed high-pressure water to deliver a powerful shock inside the pipes, effectively removing scale and foreign matter. This method minimizes the risk of pipe damage by allowing for localized concentration and control of the high-pressure water. Furthermore, it offers excellent adaptability to curved structures and confined spaces, enabling flexible responses to the structural characteristics of the piping. In addition, it provides the advantage of being environmentally friendly as it utilizes only water without chemical cleaning agents. The cleaning method utilizing eccentric nozzles offers performance differentiated from existing technologies. In particular, it is designed to achieve uniform and effective cleaning even within the complex piping structures of high-rise buildings, thereby overcoming the limitations of conventional methods. It operates smoothly even on long pipes and intricate curves, employing optimized nozzle design and control technology to prevent pipe damage. Furthermore, the simplified installation and operation of the cleaning system contribute to reduced maintenance costs. In conclusion, the high-rise building pipe cleaning method using an eccentric nozzle provides a cleaning solution suitable for the special environment of high-rise buildings and will set a new standard for pipe management as a technology that satisfies efficiency, safety, and environmental friendliness. This method is expected to overcome the limitations of existing cleaning methods and become an innovative solution for pipe management in high-rise buildings.
