Abstract
This application relates to an electrostatic precipitator with an electromagnetic wave tube comprising a carbon nanotube (CNT)-based emitter. The electrostatic precipitator includes a charger configured to include the CNT-based emitter and ionize microparticles, in contaminated air introduced from the environment, by emitting an electromagnetic wave. The electrostatic precipitator further includes a collector configured to collect the ionized microparticles to discharge clean air.
Claims10
An electrostatic precipitator with an electromagnetic wave tube comprising a carbon nanotube (CNT)-based emitter, the electrostatic precipitator comprising:
- a charger comprising the CNT-based emitter and configured to ionize microparticles, in contaminated air introduced from the environment, by emitting an electromagnetic wave;
- and
- a collector configured to collect the ionized microparticles to discharge clean air,
- wherein the charger is further configured to adjust a tube voltage of the electromagnetic wave based on a contamination level of the contaminated air, and
- wherein in response to the contamination level being higher than a preset standard, the charger is configured to change the tube voltage of the electromagnetic wave from a first voltage to a second voltage higher than the first voltage, and in response to the contamination level being lower than the preset standard, the charger is configured to change the tube voltage of the electromagnetic wave from the first voltage to a third voltage lower than the first voltage.
