Abstract

Disclosed herein is provide an electrostatic precipitator capable of allowing a charger to be thin while suppressing ozone generation. The electrostatic precipitator 1 includes a charger 10 provided with a high voltage electrode 11 receiving a high voltage from a high voltage generating circuit 40 and a counter electrode 12 facing the high voltage electrode 11 and receiving a reference voltage from the high voltage generating circuit 40, and configured to charge suspended particles by generating a discharge between the high voltage electrode 11 and the counter electrode 12; and a dust collector 20 disposed in the downstream side of an air flow direction of the charger 10 and configured to collect the suspended particles charged by the charger 10.

Dependent claims

An electrostatic precipitator comprising:

a first high voltage generator configured to generate a first high voltage and a reference voltage;
a second high voltage generator configured to generate a second high voltage;
a charger including:
a first high voltage electrode configured to receive the first high voltage, and
a counter electrode configured to receive the reference voltage,
wherein the charger is configured to charge suspended particles by generating a discharge between the first high voltage electrode and the counter electrode;
and
a dust collector disposed in a downstream side of an air flow direction of the charger including:
a second high voltage electrode, and
a ground electrode,
wherein the second high voltage is applied between the second high voltage electrode and the ground electrode, so that the dust collector collects the suspended particles onto a surface of the ground electrode,
wherein the counter electrode comprises a conductor formed of a conductive material, and a resistor covering at least one surface of the conductor, the resistor configured to suppress a discharge current between the first high voltage electrode and the counter electrode.
