PROBLEM TO BE SOLVED: To provide a moving bed type dust removing device capable of properly changing dust removing condition, preventing the scattering of sandy particles and moreover hardly damaging a heat-transfer pipe for recovering heat from the sandy particles of the moving bed. SOLUTION: In the moving bed type dust removing device in which the moving bed 30 is formed by successively moving the sandy particles packed in a dust removing vessel 11 toward down side, and high temperature dust- containing gas is circulated in the moving bed to remove the dusts in the high temperature dust-containing gas, the device is constituted so that the high temperature dust-containing gas may be circulated from the lower part of the moving bed 30 to the upper part, and the heat-transfer pipe 20 is arranged in the dust removing vessel 11, and the device is constituted so that the dusts in the high temperature dust-containing gas can be removed and also that heat recovery from the heated sandy particles can be simultaneously performed.
