Vertical ashfly decarbonizer by electric field

The utility model discloses a vertical flyash decarbonizer by electric field which orderly comprises a feeder, a disperser and a collecting tank from up to bottom, wherein, a lower end of the disperser is provided with a reticular frictional electric device, a high-voltage cathode electrostatic separator which consists of an anode plate and a cathode plate which are vertically arranged in parallel and a high-voltage power supply device is arranged between the reticular frictional electric device and the collecting tank. The utility model produces different motion tracks in a high-voltage static field according to an electricity difference of carbon and inorganic ash content in flyash, thereby achieving the separation of carbon and inorganic ash particle, so the carbon content in flyash can be greatly reduced, and a new way is provided for the resource utilization of flyash.
