Disclosed is a device including a chamber configured as a tubular body, the chamber being connected to a ground power source; a power supply device disposed outside the chamber and configured to continuously apply voltage having a magnitude set as direct current or alternating current; an emitter configured as a hollow tubular body having a plurality of cusps formed on an outer surface thereof and configured to generate plasma, the emitter being disposed in the chamber, elongated in a direction parallel to a flow direction of the processing target gas, electrically connected to the power supply device, and configured to generate nonthermal plasma; a rod configured to electrically connect the emitter and the power supply device and support the emitter; and an insulator configured to electrically insulate the rod and the chamber and prevent arcing from occurring between the rod and the chamber.

Device for reducing pollutants in indoor air, ambient air, or exhaust gas by using nonthermal plasma

Disclosed is a nonthermal plasma-based exhaust gas particulate matter reduction apparatus for preventing an arcing phenomenon, the apparatus comprising: a chamber which is a tubular body having exhaust gas flowing therein and is connected to a ground power supply; a power supply device which is disposed outside the chamber and includes a voltage generation unit for generating a steady-state voltage at which maximum efficiency of a nonthermal plasma phenomenon is generated; an emitter which is disposed inside the chamber and generates nonthermal plasma between the chamber by having the steady-state voltage applied thereto; a rod which applies the steady-state voltage to the emitter by electrically connecting the voltage generation unit and the emitter; and an arcing prevention unit which prevents an arcing phenomenon from occurring between the rod and the chamber by providing insulation between the rod and the chamber.

Non-thermal plasma-based exhaust gas particulate matter reduction apparatus for preventing arcing phenomenon

A disclosed system for reducing particulate matter in an exhaust gas includes: a first conductor provided in the form of a tubular body through which a gas stream flows, and to which a ground power supply is connected; a second conductor disposed within the first conductor and having an emitter which comes into contact with the gas stream and generates non-thermal plasma (NTP); and an insulator for electrically separating the second conductor from the first conductor, in which a predetermined level of direct current voltage is continuously applied to the second conductor.
