Reaction principle

I, the process

Na2CO3 + SO2 ? Na2SO3 + CO2 (1)

2NaOH + SO2 ? Na2SO3 + H2O (2)www.posuijx.cn/

Na2SO3 + SO2 + H2O ? NaHSO3 (3)

(1)-started for the absorption reaction;

(2) the formula of alkaline high-absorption (pH>9);

(3) for the desulfurization reaction (5<pH<9).

II, the regeneration process

2NaHSO3 + Ca(OH)2 ? Na2SO3 + CaSO3? + 2H2O (4)

Na2SO3 + Ca(OH)2 ? 2NaOH + CaSO3? (5)

(4) for regenerating main reaction type;

(5) for the lime excess regenerative response.

By regeneration of desulfurization solution after pH value can judge the level of regeneration.

Process flow

After dust, the flue gas from the boiler into swirl plate FGD counter-current contact with lye, by Cyclone rotary atomizer air full mass transfer and heat transfer of two-phase, SO2 in the flue gas is absorbed and reacts with alkaline sodium sulfite. Desulfurization of flue gas after the removal of mist and fog into the chimney.

Use of sodium hydroxide as a secondary absorbent, in a circular pool a by adding sodium hydroxide lye made the desulfurization solution and process water, the circulation pump will be lye to the absorber. Desulfurization Hou of absorption liquid from cycle slot artesian to trench, along trench since into lye reaction pool in the, in reaction pool in the joined purchased lime powder, open mixer makes desulfurization Hou of absorption liquid and lime powder full reaction, regeneration out NaOH, and generated desulfurization gypsum, reaction slurry into precipitation pool, regeneration produced of gypsum precipitation down, regeneration lye through cycle pump into absorption tower cycle using. Remove slag on a regular basis, adding the process water and sodium hydroxide.
