Abstract (en)

The decontamination device is composed of an outer body (1) with a cylindrical bore (2) protecting the mixing chamber (5). A socket (7) assembled to the outer body protects a second bore (8). The outer body has a first inlet (13) for supplying liquid to the mixing chamber and a second sloping inlet (11) for a mixture of fine grain material and air. The second inlet is located so that the air and fine grain material mixture reaches the inner wall of the mixing chamber near its upstream end.

Abstract (fr)

Le dispositif est constitué d'un corps extérieur (1) muni d'un alésage cylindrique (2) abritant la chambre de mélange (5), une douille (7) assemblée au corps extérieur (1) et abritant dans un alésage (8) un deuxième corps de révolution (8). Le corps extérieur (1) est muni d'une première admission (13) pour l'alimentation de la chambre de mélange en liquide, et d'une deuxième admission (11) oblique et décalée par rapport à l'axe de la chambre de mélange (5) pour l'entrée du mélange air et matière à grains fins. La deuxième admission (11) est située de sorte qu'un mélange air et matière à grains fins atteigne la paroi intérieure de la chambre (5) à proximité de son extrémité située en amont. <IMAGE>
