The compressed air is by oil water separator by de-oiling, dewater treatment.
The present invention workflow be：Sodium acid carbonate (mesh of ＜ 200) squeezes into sodium acid carbonate warehouse 6 by grey tank car, then
Be sent into by the storehouse pump induction system of warehouse bottom and start feed bin 3, then by start the frequency conversion auger 4 of feed bin bottom be sent into it is ultra-fine
Flour mill 5, the superfine powder for wearing into the mesh of ＞ 500 enter after returning charge auger 19 mixes with returning charge the cigarette for entering that reaction tower 1 and boiler come
Gas carries out desulfurization depickling reaction.Bulky grain thing in flue gas falls into reaction tower bottom and transports to public defeated ash system by the timing of power frequency auger
System enters big ash silo；Enter with flue gas output-response tower in the particulate matter of cyclone separator, wherein thicker particle is by whirlwind point
Fallen into after being separated from device after returning charge storehouse mixes into the returning charge auger for returning bin bottom with sodium acid carbonate and enter reaction tower 1.Flue gas
In fine particle then removed with flue gas into sack cleaner.
The beneficial effects of the invention are as follows：Sodium acid carbonate can react with the deleterious acidic composition in flue gas, so as to significantly
(desulfuration efficiency can reach more than 98%, can be by sulfur dioxide and hydrogen chloride for sulfur dioxide and hydrogen chloride content in reduction flue gas
Hourly value drop to below 10mg/Nm3)；With significant environmental protection benefit.
