Patent ID: 7364710

Claim:
A system for decomposing an organic compound, comprising: an ultraviolet decomposition unit for introducing polluted gas containing organic compounds and irradiating the polluted gas introduced with ultraviolet rays at a wavelength of less than 300 nm to decompose the organic compounds; an electrolytic water producing apparatus for producing strong alkali electrolytic water and strong acid electrolytic water and feeding them into an alkali electrolytic water feed pipe and an acid electrolytic water feed pipe, respectively; and an intermediate product treatment apparatus for introducing the polluted gas processed in, and discharged from, said ultraviolet decomposition unit, and for selectively spraying strong alkali electrolytic water and strong acid electrolytic water, fed through the alkali electrolytic water feed pipe and the acid electrolytic water feed pipe, to an intermediate product generated as a result of decomposition of the organic compound contained in the polluted gas, thereby neutralizing the intermediate product, wherein said ultraviolet decomposition unit is connected to the alkali electrolytic water feed pipe and the acid electrolytic water feed pipe through valves, respectively, so that strong alkali electrolytic water and strong acid electrolytic water are selectively introduced by the opening/closing operation of said valves, thereby accelerating decomposition reaction of the organic compounds by the irradiation of ultraviolet rays, and said intermediate product treatment apparatus is connected to both ends of a circulation pipe to which a pump is provided at an intermediate position thereof, and is provided with a pH meter for measuring the pH values of the polluted gas circulating inside the intermediate product treatment apparatus, so that strong alkali electrolytic water and strong acid electrolytic water are selectively introduced through the alkali electrolytic water feed pipe and the acid electrolytic water feed pipe depending on the measured value of the pH meter.
