Application of high-pressure water jet technology in fire hose cleaning
2025-07-14
Cleaning fire hoses after a fire is a difficult task. If the hoses are not cleaned effectively, firefighters cannot smoothly carry out the next fire fighting operation and disaster relief.
For example, during the process of setting up a water cannon position at the scene of a fire, fire hoses may become contaminated with garbage, mud, oil spills, and chemicals. After the fire fighting mission is completed and the firefighters return to the station, manual cleaning is required, which is labor-intensive, inefficient, and leads to significant water waste. In recent years, there has been a frequent occurrence of fires in the petrochemical industry. Fire brigades in petrochemical areas are equipped with a type of long-range water supply hose with diameters of 150mm, 300mm, and 400mm. After a fire, these hoses are contaminated with a large amount of oil and toxic substances. If not cleaned promptly, this will corrode the hoses, making them unsafe for reuse and posing a health risk.
In recent years, with the increasing awareness of environmental protection and the continuous maturity of high-pressure water jet technology, this technology has been increasingly used in the cleaning industry. It uses high-pressure water generation equipment to produce high-pressure water, which is then converted into a highly concentrated water jet through a nozzle. This jet impacts the surface of the object being cleaned, either directly or tangentially, separating one or more materials (adherent layers) from another object (substrate), thus achieving the cleaning purpose.
