Patent ID: 7476364

Claim:
A thermal regenerative granular-moving bed apparatus, comprising: a plurality of granular materials; a heat-and-clean unit for heating up incoming gases and simultaneously filtering the gases by the granular materials, further including at least two consecutive hopper-shaped structures, an upper portion and a lower portion opposing to the upper portion; the granular materials flowing through the heat-and-clean unit gravitationally by entering the heat-and-clean unit from the upper portion, flowing through each of the hopper-shaped structures, and leaving the heat-and-clean unit from the lower portion; the gases being introduced into the heat-and-clean unit from one side of perimeter openings between every two consecutive hopper-shaped structures, and leaving the heat-and-clean unit from the upper portion; a heating device, constructed at a predetermined location inside the heat-and-clean unit for heating the granular materials to a predetermined temperature; and a granular material-cleaning unit, constructed on top of the upper portion for providing the granular materials to the heat-and-clean unit; in which a granular path is defined as a region inside the heat-and-clean unit where the granular materials pass by.
