Study on Plasma Technology of Simulating Flue Gas Desulfurization and Resource Utilization

Abstract:

The study makes SO₂ as the control object, using strong ionized plasma discharge method for experimental research on several influence factors. These influence factors include input voltage (V), SO₂ primary concentration (C_SO2), residence time (t), and frequency (f). The influence of these factors on desulfurization rate was analyzed by single variable experiment. The relation curve of single variable influence on desulfurization rate is concluded. We have designed an orthogonal experiment to analysis the significance level of these influence variables and the optimization of these variables was made after the rule of single variable experiment. The experimental results showed that: When SO₂ primary concentration(C_SO2),oxygen content(φO₂), H₂O content(φH₂O), the residence time of gas streams flowing the reactor(t), gas flux(Q), input voltage(V) and frequency(f) are respectively 140×10^-6(V/V)~160×10^-6(V/V), 21%(V/V), 2.1%(V/V), 0.85s, 0.16m³/h, 3.0kV and 5.4kHz, the tiptop desulfurization rate was over 80%.
