The flow direction of recirculated water is in this equipment:
Recirculated water gets in the sprinkling equipment of dedusting/condensing towers 4 and sprays through first water pump 15, the recirculated water that comes out from dedusting/condensing tower 4 is introduced into external deposition pond 12, just gets back to circulating water pool 11 through behind the layering and precipitating.Guarantee the cleaning of circulating water pool 11, also can clear up the dust of from flue gas, removing very easily simultaneously;
Recirculated water gets in the sprinkling equipment of synthesis desulfurating denitrating towers 5 and sprays through second water pump 16, the recirculated water that comes out from synthesis desulfurating denitrating tower 5 gets into the circulating water pool 11 again;
In dedusting/condensing tower 4 and synthesis desulfurating denitrating tower 5; After sulfide and nitrogen oxide and the magnesia MgO reaction; Part generates magnesium sulfite and magnesium nitrite, and in circulating water pool 11, through aeration pump 18 it is carried out aeration, and then continues to be oxidized to magnesium sulfate and magnesium nitrate.Its chemical equation is:

The recirculated water utilization rate of this equipment is high, and except evaporation loss, unknown losses is few, only needs to replenish the water smoke part moisture loss of discharging with flue gas, all recycles of all the other moisture.
During the operation of absorbent feeding device:
Magnesia MgO feeds an amount of water and steam earlier in slaking jar 19, and about 80 ℃, stirs, and this moment, MgO can have the saturated Mg (OH) of 20% water-soluble formation
2Solution can improve desulfurization, denitration efficiency greatly.In circulating water pool 11, add absorbent through spiral automatic charging equipment 20 then.Its chemical equation is:
MgO+H
2O＝Mg(OH)
