Description

technical field [0001] The invention relates to a filter dust removal system, in particular to an electrostatic, particle moving bed filter and elutriation coupled dust removal system and method. Background technique [0002] The residues emitted by combustion in industrial production are an important source of PM2.5, and its removal mainly uses technologies such as mechanical dust removal, wet dust removal, electric dust removal, and filter dust removal. [0003] The cyclone separator is a mechanical dust removal technology. The dust removal mechanism is: the dust-laden airflow is rotated, and the dust particles are separated from the airflow by centrifugal force and collected on the wall of the device, and then the dust particles fall into the ash hopper by gravity. The cyclone separator is a dry gas-solid separation device, suitable for dust purification with a particle size larger than 5-10 microns, and the separation efficiency for ultrafine particles with a diameter of...
