Abstract

Ce dispositif comprend un grand nombre d'éléments répartiteurs qui font saillie verticalement sur le collecteur, chacun de ces élements répartiteurs comportant une partie supérieure fermée et ayant une forme tubu aire, les parois desdits eléments étant définies sur la majeure partie de leur longueur par un fil métallique continu 40 disposé en hélice ayant une surface externe à peu près plane et des surfaces latérales convergentes vers l'intérieur et separées à leurs extrémités internes par une surface interne arrondie soudée sur un grand nombre de tiges internes longitudinales 42 afin de délimiter une fente continue 38 en hélice ayant une largeur qui n'est pas supérieure à environ 75 mu . Application aux installations de craquage catalytique.
