Low Temperature Denitrification Technology
---------------------------------------------- -------------------------------------------------- -------------------------------------------------- ----------------------------------- Wet Cleaning Denitrification Two washing towers. The first tower with such as oxidation of NO into NO2 by NaClO2 (sodium chlorite), KMnO4 (potassium permanganate), H2O2 (hydrogen peroxide), O3 (ozone), and Na2S (Na2S)) And the like to reduce NO2 to nitrogen. Cold Plasma Slurry Denitrification The cold plasma is derived from the high-pressure discharge field where the ozone is produced, and the air or oxygen is interrupted by high-speed discharge electrons through a high-pressure discharge field (such as lightning) The free radicals form ozone with another oxygen molecule. And then developed to the need to deal with the exhaust (such as odor and VOC), directly into the high-pressure discharge field, the direct use of oxygen free radical oxidation of VOC treatment. Later found that the cold plasma can also handle NO, SO2, the principle is as follows: 1. NO oxidation into NO2, and then catalyst catalytic reduction of ammonia and other reducing agent removed. 2. Oxidation of NO into NO2 or HNOx, SO2 oxidation into SO3 and then by wet absorption equipment, alkali removal.This method is called ECO method, which can remove mercury metal. 3. To oxidize NO to NO2 or HNOx, inject NH3 with it to form NH4NO3 particles, and then remove the dust collection equipment. |
