an apparatus for purifying discharged gas installed with a discharging power feedthrough device having an insulation-enhancing body capable of effectively blocking a leakage current flow

摘要

PURPOSE: An apparatus for purifying exhaust gas is provided to greatly increase purifying efficiency of noxious gas by improving structure of a discharge power feedthrough device to effectively blocking flow of leaked current, thereby consistently ensuring stable corona discharge. CONSTITUTION: In a multistage apparatus for purifying exhaust gas which is constructed by vertically laying up multistage cartridges in a reaction chamber, each of the cartridges comprises a discharge electrode plate on which a plurality of discharge needles are formed to generate corona discharge by receiving high voltage, and on which a plurality of holes are perforated so that exhaust gas passes through the holes, and a plurality of discharge power feedthrough devices on which a ground electrode plate is parallely laid up, a plurality of holes are perforated on the ground electrode plate so that exhaust gas passes through the holes, and which inputs electricity required for corona discharge of each of the cartridges by connecting the discharge electrode plate of the cartridges to a discharge power of the outside, the multistage apparatus for purifying exhaust gas is characterized in that the discharge power feedthrough devices(60) comprises a power supply conducting wire part(52), a funnel type insulation-enhancing body(56), and a flange(53).
