| 摘要 | PURPOSE:To recover good fertilizer by adding NH3 to exhaust gas contg. NOx and SOx wherein CO concn. is not more than 10 times SOx concn. and applying radiation exposure to the mixture and heat-treating a produced by-product and decomposing sulfamic acid-based compd. CONSTITUTION:In exhaust gas contg. NOx and SOx which has been produced from a boiler 1, CO concn. is 10 times SOx concn. or below. NH3 is fed to this exhaust gas through an NH3 introduction pipe 5 and electron beams are irradiated from an electron-beam generator 8 in a reactor 7 and thereafter a by-product is recovered in a powder collector 9. This recovered by-product is led to a heat-treating device 12 through a conduit 11 and heat-treated at 130-250 deg.C to decompose sulfamic acid-based compd. contained in the by-product and taken out from a discharge pipe 17 as the by-product mainly composed of ammonium sulfate and generated gas is recirculated via a conduit 2 - a pipe 16. The forming reaction of sulfamic acid-based compd. is inhibited by existence of CO. | ||
