Patent ID: 7132088

Claim:
A granular moving-bed apparatus, including an inlet louvered wall, an outlet louvered wall opposing to the inlet louvered wall, a granular path formed between the inlet louvered wall and the outlet louvered wall, the granular path being configured for flowing thereinside a predetermined type of granular materials; each of the inlet louvered wall and the outlet louvered wall being constructed as a shutter wall so as to form a plurality of serial hopper-shaped structures for flowing the granular materials; each of the hopper-shaped structures being formed by an inlet guide plate of the inlet louvered wall and an outlet guide plate of the outlet louvered wall; the inlet guide plate, inclined by an angle γ in ”, further having an inlet lower end and an inlet upper end; the outlet guide plate, inclined by an angle “γ out ,” further having an outlet lower end and an outlet upper end; each of the hopper-shaped structures further having an inlet upright fence stading at the inlet upper end of the inlet guide plate and an outlet upright fence standing at the outlet upper end of the outlet guide plate; the granular path having thereinside a plurality of serial roof-shaped flow-corrective elements, each of the roof-shaped flow-corrective elements being corresponding to one of the hopper-shaped structures and further having an inlet corrective plate adjacent to the inlet guide plate and an outlet corrective plate adjacent to the outlet guide plate; the inlet corrective plate further having an inlet corrective tip; the outlet corrective plate further having an outlet corrective tip; the inlet upper end spacing from a line parallel to a centerline of the granular path and passing the inlet corrective tip by a length in the outlet upper end spacing from a line parallel to the centerline of the granular path and passing the outlet corrective tip by a length out the inlet upper end spacing from a line perpendicular to the centerline and passing the inlet lower end of a preceding hopper-shaped structure by a length in the outlet upper end spacing from a line perpendicular to the centerline and passing the outlet lower end of the preceding hopper-shaped structure by a length out the apparatus characterized in that: the inclination of the inlet corrective plate is equal to the γ in , the inclination of the outlet corrective plate is equal to the γ out , the inlet corrective tip is arranged above the inlet upper end by an inlet predetermined distance “H in ” ranged between 0.1 S in to 0.9 S in , and the outlet corrective tip is arranged above the outlet upper end by an outlet predetermined distance out ranged between 0.1 S out to 0.9 S out , wherein said inlet corrective tip and said outlet corrective tip are separated.
