Moving bed granular layer dust fog removing device

The invention discloses a moving bed granular layer dust fog removing device which is high in defogging efficiency and can be recycled. The moving bed granular layer dust fog removing device comprises a cylindrical shell; a moving bed shell which is horizontally arranged passes through the cylindrical shell and is fixedly connected with the cylindrical shell; the moving bed shell is provided with a through hole which is communicated with the cylindrical shell; the moving bed shell is internally provided with a moving bed; the moving bed comprises a drive roller, a driven roller and a rolling belt which is jointly driven by the drive roller and the driven roller; the rolling belt corresponds to the through hole and is provided with a vent hole; a granular layer material distribution space is arranged above the rolling belt; the moving bed shell is provided with a discharge hole and a feeding hole in the positions corresponding to the two ends of the rolling belt. The moving bed granular layer dust fog removing device adopts a moving bed way, so that a granular layer on the moving bed is slowly moved, and the dust fog can be conveniently removed from the airflow passing through the granular layer. The granular layer is evenly arranged, and the removal efficiency reaches 99%.
