Abstract[English]
A device for stripping a particulate gas-solid mixture, comprising a pipe and a pre-stripping chamber (10) connected to the pipe (9), the pre-stripping chamber comprising: a vertical barrel (27) having a closed upper side and an open lower side; a vertical outlet pipe (31) which opens the upper side of the barrel along substantially the vertical central axis of the barrel; a narrowing cone (28) extending and narrowing the vertical wall of the barrel downwards at an angle α3 of between 45° and 88°; a tube (29) placed in the centre of the narrowing cone, the lower end of the tube being placed below the lower end of the narrowing cone, the tube and the lower end of the narrowing cone together forming an annular space; and a widening cone (30) extending and widening the tube downwards at an angle α4 of between 45° and 88°.[French]
Dispositif de strippage d'un mélange gaz-solide particulaire, comprenant une conduite et une chambre de pré-strippage (10) connectée à la conduite (9), la chambre de pré-strippage comprenant : un baril (27) vertical présentant un côté supérieur fermé et un côté inférieur ouvert; une conduite de sortie verticale (31) ouvrant le côté supérieur du baril selon sensiblement l'axe central vertical du baril; un cône de rétrécissement (28) prolongeant et rétrécissant vers le bas la paroi verticale du baril selon un angle α3 compris entre 45° et 88; un tube (29) disposé au centre du cône de rétrécissement, l'extrémité inférieure du tube étant disposée en dessous de l'extrémité inférieure du cône de rétrécissement, le tube et l'extrémité inférieure du cône de rétrécissement formant ensemble un espace annulaire; un cône d'élargissement (30) prolongeant et élargissant vers le bas le tube selon un angle α4 compris entre 45° et 88°.
