METHOD AND DEVICE FOR DESULFURIZATION AND DENITRATION

摘要

PURPOSE: A method for desulfurization and for denitration among exhaust gas is provided to remove by generating a sulfuric acid ammonium and a nitric acid ammonium with reacting with a counter agent in a neutralized reacting device after converting a SO2 and a NOx contained in exhaust gas to a H2SO4 and a HNO3 by processing with electronic rays. CONSTITUTION: An SO2, and a NOx contains in exhaust gas are oxidized to a sulfuric acid and a nitric acid through a radical reaction by reacting with electronic rays irradiated from an accelerator of electric rays(21) by flowing exhaust gas ventilated from a boiler(10) into a reactor of electric rays(20). The processing efficiency of electric rays is improved by maintaining the high temperature inside the reactor of electric rays(20). The oxidized sulfuric acid and the nitric acid are generated to a neutral chloride of a sulfuric acid ammonium and a nitric acid ammonium by reacting with an alkali aqueous solution sprayed from a spray of alkali aqueous solution(40) inside a moving duct(50) moved to an electric collector(14). The sulfuric acid ammonium chloride and the nitric acid ammonium chloride are removed by collecting in the electric collector(14), and the purified exhaust gas is released to air by delivering to a chimney(16) through a ventilator(15).
