The electrostatic precipitator(EP) with rotating polar plate is a new type EP adopts rotable polar plate and rotating brush to remove the collected dust.The technical properties of electric field around the rotating polar plate in said EP

including eliminating secondary fugitive dust

avoiding the phenomenon of back corona

enhancing the efficiency of dust removal

and constucting ultra-large EP etc.

have been presented.Through comparison with commonly used dust removal equipments

such as EP

bag type dust arrester

and composite dust remover of them

in aspects of technology and economic efficiency

the EP with ratating polar plate has more advantages in aspects of suitability to operating conditions

to coal sorts

to safety

to electricity consumption

and to operation cost.
