Abstract:
1. A plasma reaction apparatus comprising: a furnace being hollow, the furnace including a first raw material inflow pipe connected to a lower part of the furnace for supplying a first raw material into the furnace, the first raw material inflow pipe being configured to receive the first raw material for a plasma reaction, a discharge opening formed in an upper side of the furnace, the discharge opening being configured to discharge a plasma reactant, and a broad area chamber having a predetermined width and positioned within inside the furnace, the broad area chamber being configured to expand a plasma reaction zone and let the plasma reaction zone temporarily stay in the broad area chamber upon the plasma reaction of the first raw material being supplied into the furnace; an electrode inserted in a bottom wall of the furnace, protruded into the furnace, and spaced from wall surfaces of the furnace at a predetermined interval the electrode being configured to generate a discharge voltage for the plasma reaction of the first raw material; a heat absorption tank positioned in the broad area chamber, the heat absorption tank being connected to a second raw material inflow pipe and a first material supply pipe, the heat absorption tank having a heat absorption chamber, the heat absorption chamber being formed in the heat absorption tank and having a spherical shape, the heat absorption chamber including a heating unit within the heat absorption chamber, the heating unit being configured to heat a liquefied second raw material flowing through the heat absorption chamber, the second raw material inflow pipe opening into the heat absorption chamber for supplying the second raw material to the heat absorption chamber, and a first end of the first raw material supply pipe opening into the heat absorption chamber so as to supply the second raw material from the heat absorption chamber into the furnace, wherein a part of the first raw material supply pipe is wound around an outer circumferential surface of the furnace; and a mixing tank formed on an outer wall of the furnace, the mixing tank being connected to the first raw material inflow pipe and a second end of the first raw material supply pipe, the mixing tank having a mixing chamber, the mixing chamber being configured to mix the raw materials from the first raw material inflow pipe and the first raw material supply pipe and supply these materials into the furnace, wherein an upper part of the furnace is bent to form a step at a right angle so that the discharge opening is displaced laterally from a vertical extension line of the broad area chamber, wherein an upper part of the electrode has a conical shape and a lower part of the electrode has a cylindrical shape such that a width of a middle part of the electrode between the lower and upper parts is larger than respective widths of the upper and lower parts, the upper, lower and middle parts being exposed in the interior of the furnace, wherein the electrode includes a raw material inflow chamber, a second raw material supply pipe connected to a bottom end of the electrode and configured to carry additional liquefied raw material into the raw material inflow chamber, and an inflow path formed through wall of the electrode and configured to allow the additional raw material in the raw material inflow chamber to flow into the furnace, and wherein the second raw material supply pipe is connected to a gas supply pipe configured to carry a gas into the raw material inflow chamber so as to atomize the additional liquefied raw material.
