Removing Method of Elemental Mercury Contained in Emission Gas by Using Chlorinated Chemicals

摘要

The present invention NaClO ₂ of the flue gas that contains elemental mercury and NOx removing oxidized mercury from the NaClO ₂ injection step , the NaClO ₂ and the NOx is to call the elemental mercury to oxidized mercury with an oxidizing agent to form a transition step and the exhaust gas injection to provide a mercury removal method which is characterized in that it comprises a mercury oxide removal step. ; According to the method of the present invention , the exhaust gas in NaClO ₂ less a small amount of mercury contained in the exhaust gas by injecting effective to generate an oxidizing agent capable of oxidizing elemental mercury to It can be efficiently removed by .
