Abstract: A thermal regenerative granular-moving bed apparatus for a gas de-pollutant process includes a plurality of recycling granular material, a heat-and-clean unit, a heat-recycling unit, and a granular material-cleaning unit. The heat-and-clean unit heats the granular material to further heat a polluted gas, de-pollutes the gas, and detains pollutants or particles from the de-polluting. The heat-recycling unit constructed on top of the heat-and-clean unit has the hot up-flowing de-polluted gas heat-exchange with the down-flowing cold granular material. The granular material-cleaning unit transports the granular material from a lower-end of the heat-and-clean unit to an upper end of the heat-recycling unit and re-activates the granular material during the transportation.

Abstract: A granular moving-bed apparatus is introduced to have an inlet louvered wall, an outlet louvered wall opposing to the inlet louvered wall, a granular path formed in between, a plurality of serial roof-shaped flow-corrective elements located along the granular path, and a predetermined type of granular materials flowing inside the granular path. The inlet louvered wall and the outlet louvered wall are particularly constructed to form serial hopper-shaped structures that define the granular path. The roof-shaped flow-corrective element is systematically displaced with respect to the hopper-shaped structure by specific criteria so that problems of corrosions, plaques and stagnant zones formed to the louvered walls of the apparatus can be avoided.
