AIR POLLUTANT TREATMENT EQUIPMENT AND METHOD USING PLASMA

摘要

PURPOSE: Air pollutant treatment equipment and its method by using plasma is provided for eliminating the air pollutant such as sulfur dioxide, nitrogen oxide, dioxin, etc. contained in exhaust gas generated from an iron-ore sintering plant, thermal power plant, etc. in plasma condition using pulse corona discharge. CONSTITUTION: Air pollutant treatment equipment (100) comprises a direct-current (DC) high-voltage supplier (110) for supplying the DC high-voltage; a pulse high-voltage generator (120) for outputting the DC high-voltage applied from the DC high-voltage supplier (110) by converting to the pulse high-voltage; a step-up transformer for elevating the pulse high-voltage output from the pulse high-voltage generator (120); a magnetic switch (140) for providing a pulse interval of the elevate pulse signal to a responsor after converting to a short interval by the step-up transformer (130); a plasma responsor (150) for generating corona discharge in a case of applying the pulse high-voltage from the magnetic switch (140) to a discharge pole; and a discharge circuit section (160) for discharging the full-charged high-voltage to the plasma responsor (150) after corona discharging.
