The application provides a device and a process for gasification and ashing of carbon-containing organic matter, and relates to the technical field of carbon-containing organic matter treatment. The device comprises a cylindrical furnace body, a cylindrical shaft vertically arranged in the furnace body, and multiple layers of furnace beds perpendicular to the cylindrical shaft. Each of the furnace beds is circumferentially provided with a hollow rotating rake and a magnetic force generator. The rotating rake is in communication with the cylindrical shaft, and the gap between the rotating rake and the magnetic force generator in the furnace bed is provided with a bed of piezoelectric material.
