Patent

CA 2217503

A non-mechanical valve (3) for controlling the flow of fluidisable solids is disclosed. The valve (3) comprises a pipe having an upstream leg (5) with a solids inlet (13) at an upper end, a downstream leg (7) with a solids outlet (14) at an upper end, and a base section (9) interconnecting lower ends of the legs (5, 7). The valve (3) further comprises a means for introducing aeration gas into each of the legs (5, 7) to maintain fluidised flow of solids through the valve (3) and a means for adjusting the flow of aeration gas to the legs (5, 7) to control the solids flow through the valve (3).

Vanne (3) non mécanique permettant de réguler le flux de solides fluidisables, qui comprend une conduite ayant une branche (5) amont dotée d'un orifice d'entrée (13) pour matières solides à une extrémité supérieure, une branche (7) aval dotée d'un orifice de sortie (14) de matières solides à une extrémité supérieure et une base (9) interconnectant les extrémités inférieures des branches (5, 7). Ladite vanne (3) comporte en outre un dispositif permettant d'introduire du gaz d'aération dans chacune des branches (5, 7) pour maintenir un flux fluidisé de matières solides à travers ladite vanne (3) et un dispositif permet de régler le flux de gaz d'aération acheminé vers les branches (5, 7) pour réguler le flux de matières solides à travers la vanne (3).
