DEVICE AND METHOD FOR HYDRODYNAMIC CLEANING OF SURFACES BASED ON MICRO-HYDROPERCUSSION EFFECT Russian patent published in 2018 - IPC B08B3/02 B05B1/02 

Abstract RU 2641277 C1

FIELD: machine engineering.

SUBSTANCE: head for hydrodynamic cleaning is a flow channel with a profile, a resonance chamber and a diffuser formed coaxially with each other by an input confusor, resonance chamber and diffuser. The confuser and diffuser are connected by the resonance chamber in the form of a transition projection. The ratio of the area of the outlet cross-section of the confuser to the cross-section area of the resonance chamber opening forming the transition projection is 1.5-8.97. The diffuser may contain a device for additional supply of liquid, gas or solid particles. Preferably, the confuser has a conical shape and a cone angle of 10-20°. Preferably, the diffuser has a conical shape and the taper angle of 15-70°.

EFFECT: high-performance, stable and sufficient for practical tasks cavitation at possible more low pressures and flow rates for cleaning surfaces from man-made and natural contaminations both in liquid and air environments.
