Electron beam flue gas scrubbing treatment

摘要: A flue-gas scrubbing arrangement removes sulfur oxides and nitrogen from stack gases at low energy costs converts these into non-noxious ammonium sulfate-nitrate, which is utilizable as an agricultural fertilizer. The flue gases, cleaned of fly ash, pass through a spray dryer, where water spray-injected to cool humidify the gas. Then humidified gas passes e-beam reactor high electrons bombard oxygen create strong reagents that react with SO2 NOX form sulfuric nitric acids. These ammonia injected stream sulfate nitrate salts ammonia. should be present in near stoichiometric amounts relative oxides. moisture entrained wet precipitator, are removed aqueous solution, remaining, scrubbed stack. solution then fed back incoming pick up precipitate sulfate-nitrate particles about 100 μm. Cooling electron beam generation equipment can used make-up for dryer.
