Abstract
A plasma scrubber that forms a high temperature atmosphere in a reactor to effectively decompose and remove a non-biodegradable gas and reduce power consumption is disclosed. The plasma scrubber includes: a first reactor to which a non-biodegradable gas is supplied; an electrode installed in the first reactor and protruding in the flow direction of the non-biodegradable gas to generate plasma in the non-biodegradable gas supplied between the electrode and the first reactor by a discharge reaction in the first reactor; a second reactor connected to the first reactor to form continuous arc jets by anchoring the plasma to the electrode; and a third reactor connected to the second reactor to decompose the non-biodegradable gas by forming a reaction section of high temperature that contains electrons and chemical species of high reactivity in the second reactor and thereby increasing the stay time and reactivity of the non-biodegradable gas.
