Apparatus for treating exhaust particulate matter
An apparatus treats harmful particulate matter generated through combustion. The apparatus includes a concentrator concentrating the harmful particulate matter and a plasma generator burning the concentrated harmful particulate matter. Thereby, the harmful particulate matter can be efficiently removed.
1. An apparatus for treating particulate matter generated through combustion, the apparatus comprising:
a pipe through which harmful particulate matter passes, the pipe comprising an inlet and an outlet;
a concentrator comprising:
a discharge electrode installed on an inner surface of the pipe; and
a core installed inside the discharge electrode along a central axis of the discharge electrode, the core having a first end positioned towards the inlet of the pipe and a second end positioned towards the outlet of the pipe opposite the first end, wherein the discharge electrode is operable to charge the harmful particular matter and the core is operable to attract the charged harmful particulate matter toward the core, thereby concentrating the harmful particulate matter; and
a plasma generator installed in the pipe at the second end of the core along the central axis of the discharge electrode and generating plasma to burn the concentrated particulate matter exhausted from the concentrator, the plasma generator including
two electrodes arranged along a central longitudinal axis of the pipe and having respective opposing faces being in an arc shape.
2. The apparatus according to claim 1 , wherein the core of the concentrator tapers off toward the second end.
