Abstract

The invention relates to gas-abrasive processing and can be used for cleaning building structures and technological equipment with the aid of a two-component jet. Said jet is formed by acoustical action, oscillation of a material socket and by increasing a pressure difference at gas input and the output thereof. The inventive method consists in accelerating abrasive particles by an accelerator in a channel whose length ranges from 30 to 120 diameters thereof and in directing said particles at an angle of 15-45° with respect to a processed surface at a distance from the nozzle ranging from 35 to 95 diameters. A desired ratio between dispersed and dispersing media is maintained with the aid of a self-adjusting pneumatic system by increasing oscillation and reducing gas-flow rate in the jet supplied to the material socket. The inventive device for carrying out said method for bead-blasting processing comprises a nozzle, a reservoir provided with a dosing unit which are connected to each other by a transport pipe and to a pressure gas source by means of a gas conduit. Said nozzle is embodied in the form of a channel whose length ranges from 30 to 120 diameters thereof. Said dosing unit comprises a wideband acoustical oscillator, a multi-circuit vibration exciter provided with an ejector, an activator and a centrifugal moisture separator.
