ELECTROSTATIC DUST PRECIPITATOR

摘要

An electrostatic dust precipitator (1) comprising a housing (11) having an air passage (10) interconnecting a suction opening (8) and an exhaust opening (9), an air-flow generating section (14) for generating an air flow in the air passage (10), a discharging section (2) and a discharge guide section (3) for charging fine particles (103) through corona discharge (100), a charging section (4) for repelling the fine particles (103) charged through corona discharge (100) with a Coulomb force, an attracting section (5) for attracting and collecting the fine particles (103) with a Coulomb force, a voltage supply section (15) supplying a discharge voltage for generating corona discharge (100) and for repelling the fine particles with a Coulomb force at the charging section (4), and a drive control section (20) for rotary driving a discharge plate and an attraction plate.
