Title: Aiding loose particle descent against rising gas - in reactor by mechanical vibrators or air jets between angled support floor projections
IPC: B01J8/12
Filed: 1989-12-19
Abstract: Inside a cylindrical reactor, a rising stream of gas is purified by contact with a descending mass of solid particles.  Gas enters the side wall of a conical lower reactor section terminating in a base outlet for used solids. The solids are supported by concentric circular rib structures formed of pairs of strips angled in roof-fashion, leaving gaps to admit rising gas and retain the solids. Below the gaps are carrier plates wide enough to match the angle of repose of solids in static conditions. Fingers spanning the roof-strips and entering the descending particle mass are coupled to arms which are vibrated in both circumferential directions by lines, promoting descent of solids. In a variation the centre of each carrier plate carries a perforated gas ejector pipe for loosening descending solids. ADVANTAGE - Gravity-flow is maintained with min power consumption.

Title: Smoothing roll extruder with improved output - has feed inlets at both ends of roll which has screw profile ends
Inventor: BECK ERICH DIPL ING
IPC: B29C48/465
