Abstract:
An apparatus for bringing solids in the form of pourable pieces into contact with fluids or for bringing solids into contact with fluids and gases in a reactor by guiding the reactants together, the reactor comprising a reactor housing with a screen support in the reactor housing and, in this latter, a screening support in the area of which the contacting takes place, whereinthe screening support is constructed as a rotating, concentric screening drum (5) mounted on at least one hollow shaft (6) provided with means (29) for transporting solids through the hollow shaft(s) into the drum (5) interior;the screening drum (5) is, when in operation, rotatable in a bottom tank (10) in which there is a gaseous or liquid medium which reacts with the solids, and the bottom tank (10) can be lowered until such time as the solid pieces in the screening drum (5) and the medium in the bottom tank (10) can be separated from each other to vary the degree of or to interrupt the chemical reaction or the physical process by the lowering of the bottom tank (10).
