    • The present invention relates to a device with a rotating fluidized bed in one or a succession of cylindrical chambers, in which injectors (12), distributed around the fixed circular wall (2) of said cylindrical chamber(s), inject along this wall, in successive layers, one or more fluids (13), which entrain the solid particles (17), passing through this/these chamber(s), in a movement of rapid rotation whereof the centrifugal force concentrates these particles along this wall, thereby forming a fluidized bed rotating around a central duct or a plurality of central ducts (3), through which the fluids are removed. The present invention further relates to a method of catalytic polymerization, drying or other treatments of solid particles in suspension in a rotating fluidized bed or of catalytic conversion of fluids passing through said rotating fluidized bed using a device according to the present invention.

    • A number of different, efficient treatments of slurries and liquid with gas can be provided. A slurry or liquid is introduced into a first end of a vortex. A gas--such as a chemically reactive gas--is introduced from exteriorly of the vortex into contact with the slurry or liquid in the vortex, so that a desired reaction between the slurry or liquid and the gas takes place. The treated slurry or liquid is removed from the second end of the vortex while any residual or carrier gas is removed from the first end of the vortex. Gas introduction is preferably accomplished through a porous surface of revolution (e.g. cylindrical or conical) wall surrounding the vortex, the gas being in minute bubble form when it enters the slurry or liquid. This has particular applicability in the treatment of paper pulp using an ozone containing gas, or in reacting various liquids in the paper and pulp industry with gas (such as reaction of caustic solutions with chlorine or chlorine dioxide gas), the stripping of a strippable component from a liquid (e.g. stripping black liquor soap from black liquor, using air), or absorbing an absorbable component in a gas into a liquid (such as absorbing ozone, chlorine, or the like in water), or scrubbing furnace flue gases. Gas may also optionally be removed from adjacent the second end of the vortex through a separate conduit from the gas being removed from the first end of the vortex.
    • 可以提供许多不同的,有效的处理浆料和液体与气体。 将浆液或液体引入涡流的第一端。 气体(如化学反应气体)从涡流外部引入与涡流中的浆液或液体接触,从而发生浆液或液体与气体之间所需的反应。 从涡流的第二端除去处理后的浆料或液体,同时从涡流的第一端除去任何残余的或载气。 气体引入优选通过围绕涡流的旋转的多孔表面(例如圆柱形或圆锥形)壁进行,气体在其进入浆料或液体时处于微小气泡形式。 这对于使用含臭氧气体的纸浆处理或使纸和纸浆工业中的各种液体与气体(例如苛性碱溶液与氯气或二氧化氯气体的反应)反应的纸浆处理特别适用,剥离可剥离组分 或者将气体中的可吸收组分吸收到液体中(例如在水中吸收臭氧,氯等)或洗涤炉烟道气。 气体还可以通过与从涡流的第一端除去的气体分开的导管从涡流的第二端相邻地移除。
