Patent ID: 8574504

Claim:
A plasma scrubber comprising: a first cylindrical reactor to which non-biodegradable gas is supplied and a voltage is applied; an insulator coupled to one end of the first cylindrical reactor and closing the one end of the first cylindrical reactor; an electrode to which a voltage is applied, the electrode having one end coupled to the insulator and insulated from the first cylindrical reactor and an opposite end received in the first cylindrical reactor and spaced apart from an inner surface of the first cylindrical reactor, the electrode having an expansion section that gradually expands toward the inner surface of the first cylindrical reactor along the length of the electrode in a direction from the first reactor to the second reactor; a maximum diameter section formed at one end of the expansion section; and a contraction section that gradually contracts away from the inner surface of the first cylindrical reactor along the length of the electrode in a direction from the first reactor to the second reactor; the electrode including a sharp end centered on an axis; a second cylindrical reactor having one end coupled with an open end of the first cylindrical reactor, the one end of the second cylindrical reactor having an inner diameter approximately equal to an inner diameter of the first cylindrical reactor, the second cylindrical reactor including an end section opposite the one end having an inner diameter that gradually decreases along a length of the end section reactor in the direction from the first reactor to the second reactor, an end of the end section forms a closed end, the closed end including a jet hole centered on the axis; a third cylindrical reactor coupled with the closed end of the second cylindrical reactor and having an inner diameter larger than the inner diameter of the one end of the second cylindrical reactor; and wherein the first cylindrical reactor includes first gas supply holes and the first gas supply holes face the expansion section of the electrode; wherein the electrode includes second gas supply holes and the second gas supply holes face the first cylindrical reactor from the expansion section; and wherein the electrode includes: a supply passage formed in the interior of the electrode to supply one of water, an oxidizing agent, a fuel and an inert gas into the first cylindrical reactor; and a porous section connected to the supply passage.
