1. Basic Principle The high voltage pulse generated by the pulse power supply is applied to the reactor electrodes, creating a strong electric field between the reactor electrodes. Under the action of the strong electric field, some flue gas molecules are ionized. The ionized electrons gain energy under the acceleration of the strong electric field and become high-energy electrons (5~20eV). The high-energy electrons can activate, crack, and ionize other flue gas molecules to produce various active particles and free radicals such as OH, O, and HO2. In the reactor, SO2 and NO in the flue gas are oxidized by active particles and free radicals into higher-order oxides SO3 and NO2, which meet H2O in the flue gas to form H2SO4 and HNO3. When NH3 or other neutralizers are injected, an aerosol of (NH4)2SO4/NH4NO3 is generated, which is then collected by a dust collector. The electric field itself of the pulse corona discharge flue gas desulfurization and denitrification reactor also has a dust removal function. 2. Technical features: It has the advantages of simple installation, low operating cost, complete removal of harmful pollutants, and no secondary pollution. 3. Application fields Flue gas containing sulfur dioxide and nitrogen oxides produced by coal-fired power plants, chemical industry, metallurgy, building materials and other industries.
