Study On Flue Gas Desulfurization With Pyrolusite Pulp In The Circulation Reactor

The huge sulfur coal combustion resulted in the serious pollution of SO2 and acid rain have destroyed the ecological balance seriously. Removing the SO2 from the flue gas is a main subject in the filed of reducing SO2 pollution. This paper has studied a new Flue Gas Desulfurization (FGD) technology. Experiments are carried out in a Circulation Reactor designed by us, with pyrolusite pulp serving as desulfruization agentThe technological and structural parameters applied in catalyzed oxidation with the catalyst of Manganese Ore in the process of FGD have been studied. The structural parameters have been optimized through altering the pore rate of sprayer of the reactor, depth of submergence of the sprayers of the separator; Secondly, We have studied the effect of operating factors to the desulfurization rate and the leaching ate of the Mn. These factors include the ration of liquid quantity and the solid quantity, the ration of gas flow quantity and concentration of the SO2 of the flue gas. Then, we have get better operating factors. Finally, we study the principle of react and reactor.The resultus show that the desulfrization rate and the leaching rate of Mn can be kept at high level under the condition of continuous operation. Thus, This technology can get rid SO2 from flue gas by making the best use of profuse lowgrade pyrolusite ore in china to produce MnS04 and H2SO4 with sells well. It shows the technologyhas both environmental benefit and economic benefit. The studied in this paper lay the solid foundation for the application of this Study on Flue Gas Desulfurzation with Pyrolusite Pulp in the Circulation Reactor in industry.
