Abstract (en)
[origin: US4633623A] Sand blasting nozzle, particularly for the decontamination of radioactive members by means of a jet formed from a mixture of water and abrasive particles. It comprises an intake device able to produce a flat water jet, having an aperture angle alpha in the plane of the jet, within a vacuum chamber, a discharge member having in planes perpendicular to the flat jet, two divergent side walls substantially of aperture alpha and, on either side of the flat jet, two convergent walls forming an angle beta , said discharge member forming an integral part of the vacuum chamber, and the angle beta being defined in such a way that within the chamber is produced an adequate vacuum to ensure that the flat jet entrains the abrasive particles introduced by a pipe carrying a mixture of gas and abrasive particles.
