SDBAGTM AND SDEPTM SYSTEM TECHNOLOGY FOR DE-DUST, DE-SOX AND DE-NOX

摘要

IntroductionSimultaneous removal technologies for Sox, Nox and dust have been researched and developed by various research teams. Most FGD(Flue Gas Desulphurization) process used one of dry, semi-dry or wet scrubber type, and well known method of de-Nox technologies are SNCR(Selective Non-Catalytic Reduction), SCR(Selective Catalytic Reduction) and chemical oxidization reduction. Dust can be removed by one of popular bagfilter system or ESP(Electro-Static Precipitation). Recent exhaust pollutant removal technologies have been upgraded to the hybrid, combined and simultaneous treatment ways for the benefits of process simplicity. [1]～[3]In this paper we introduce newly combined technologies of SDBAG and SDEP system, which can treat simultaneous de Sox/Nox and de-dust functions in one body. SDBAG? Is combined system of SDR(Semi Dry Reactor) for the Sox treatment and Bagfilter for the dust collection. SDEP? Is similar combination system of SDR and ESP. These systems use chemical oxidation and reduction method for de-Nox treatment.
