SHAFT WITH MOVING LAYER OF LOOSE MATERIALS Russian patent published in 1994 - IPC

FIELD: separation of gases. SUBSTANCE: the shaft has horizontal discharge members made of plates that are placed under each other and are impenetrable for material and gas atmosphere. The plates are disposed with a side shift so that the gap formed for passage of loose material converges downward. The width of the lower plate exceeds the gap for passage of loose material formed by the overlying plates. The distance between the plates and their width are selected from the condition that on fixed plates loose material is arranged with formation of a stable angle of natural slope. EFFECT: facilitated procedure. 6 dwg
