FIELD: process engineering.
SUBSTANCE: invention relates to cleaning of surfaces of coats and contaminants. Proposed method consists in surface processing by high-temperature high-rate cavitating water jet. In compliance with this invention, at pressure increase working fluid is subjected to vibroacoustic effects at frequency multiple of those of resonance water cluster excitation. Working fluid pressure makes at least 9.0 MPa. Working fluid temperature is not lower than boiling point. Proposed device comprises high-pressure pump, heater, nozzle and assembly for vibroacoustic effects with frequency control unit.
EFFECT: higher efficiency of cleaning, possibility for cleaning outdoors.
