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. By providing the thermal regenerative granular-moving bed apparatus, heating, de-polluting and filtering upon the gas can be carried out in a single unit, and also energy in the de-polluted gas can be transferred and thus saved to pre-heat the cold granular material.
