Novel dual-alkali method desulfurization system：Compound alkali Dual alkali does not use the Na salt systems of forceful electric power solution, but has used ADS
Desulfurization carrier forms ADS (OH) n-ADS (SO4) 0.5n-ADS (SO3) 0.5n solution systems of weak electrolytic equilibrium；Coordinate simultaneously
CA calcium dissolution accelerator, pH buffer so that system promotes ADS (SO4) 0.5n, ADS (SO3) 0.5n between pH5.5-7.0
The generation of equal sulfate（Flue gas desulfurization course）, and pH promotes the generation of ADS (OH) n between 7.0-8.0, that is, promotes CaSO4
The generation of precipitation（Regenerative process）.By the variation of solution system, ADS (SO4) 0.5n, ADS (SO3) 0.5n regeneration lifes can be made
It is improved to 90% or more at the efficiency of ADS (OH) n, generate NaOH efficient 2 times is regenerated than Na2SO4, Na2SO3.This is novel
Dual alkali can avoid the basic reason of sulfuric acid salt accumulation.
Low concentration system running：It, can be in the low solution for reaching saturation far away since ADS desulfurization agent carrier desulphurizing abilities are strong
Ideal desulfuration efficiency is obtained under concentration（Solution system total ion concentration<15g/L）, low compared with the ion concentration of sodalime double alkali method 2/
3, this is also one of the reason of compound alkali Dual alkali is avoided that Crystallization Plugging.
Reaction regeneration is equipped and process monitoring system：In order to ensure the regeneration efficiency of compound alkali ADS desulfurizing agents, further contract
Small regenerated reactor volume, enhance process control and automatization level, also mating to have developed multiphase regeneration reactor, ion concentration automatic
Monitor and detection is equipped and control system, forms from medicament, the overall technology achievement equipped, be designed into control.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
Should all it cover within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection domain of claims
Subject to.
