Abstract To address the problems of high labor intensity, low efficiency, and the tendency to contaminate the environment associated with conventional cooling tower cleaning methods, this study takes a circular high-pressure divergent nozzle as the research object and aims to propose an efficient and automated cleaning solution for cooling tower water collection trays. Through theoretical analysis, deriving the calculation formulas for characteristic parameters such as the jet flow rate and impact force on the target, and using the control variable method, the effects of initial jet pressure and jet cone angle on jet characteristics are investigated, from which the optimal cleaning parameter settings are deduced accordingly. The results show that, under the conditions of a nozzle diameter of 2 mm and a standoff distance of 0.8 m, the high-pressure water jet achieves a cleaning efficiency improvement for the cooling tower water collection tray while ensuring cleanliness when the initial pressure is 0.3 MPa, and the jet cone angle is 47°.
