Abstract: The present invention discloses an immersion type rotating packed-bed reactor and an application thereof. A rotor filler is immersed in materials in the reactor; under the driving of the rotation of a rotor, the materials in the reactor form a loop; and when passing through the filler, the materials are fully sheared and dispersed into fluid micro-elements, so that the mass transfer rate and the reaction rate are increased. A feeding assembly simultaneously introduces materials of different phases to an inner edge of the rotor, a retaining ring and a baffle function to break a vortex, and a heat exchange assembly can maintain a system in a suitable temperature range. The present invention is suitable for heterogeneous systems such as a gas-liquid system and a liquid-liquid system. Compared with a conventional rotating packed bed, the material contact time is long, so that the reaction is more complete.

Abstract: A rotary bottom ash regenerating (RBAR) system [100] comprises a cylindrical body [110] that receives ash [17] containing reactant particles [10] that are partially reacted limestone compounds having unreacted cores [13] from a furnace. Sensors [140] sense physical parameters within the cylindrical body [110]. A controller [170] receives the output of the sensors [140] and information indicating the amount of unreacted core [13] and causes a fluid actuator [135] to spray a proper amount of regeneration fluid regulator [135] from a plurality of spray nozzles [131] to different locations within the cylindrical body [110] to regulate the temperature and to cause the reactant particles [10] to have a require content of regeneration fluid. This causes the reactant particles [10] to be regenerated and reused. This results in a lower limestone costs and less overheating of ash handling systems.
