Lime white (using the Dual alkali of sodium hydroxide+Calx, and magnesium hydroxide, principle is the most identical) and the SO in flue gas in traditional wet method2Reaction generates calcium sulfite, and (Dual alkali first passes through sodium hydroxide reaction, and the latter and lime white are reacted to calcium sulfite and restore sodium hydroxide.Sodium hydroxide solution Reusability.Clean reaction is that calcium hydroxide reacts generation calcium sulfite with sulfur dioxide)；Traditional dry desulfurization is to spray into calcium carbonate with coal dust in fine coal CFBB to enter boiler furnace, and Decomposition of Calcium Carbonate generates calcium oxide, and the latter generates calcium sulfate with a part of oxysulfide；And Roche dry desulfurization simply uses Calx or magnesium hydroxide and oxidation catalyst, wherein catalyst oxidation SO2Become SO3, the latter is with lime reaction becomes calcium sulfate or reacts generation magnesium sulfate/Magnesium hydrogen sulfate etc. with magnesium hydroxide.
Conventional dry desulfurization: CaCO3→CaO+CO2 SOx+CaO→CaSO4
Conventional wet desulfurization: SO2+Ca(OH)2→CaSO3+H2O。
