【摘要】：為了考察等離子體活化空氣產(chǎn)生臭氧對脫硫漿液中亞硫酸鈣的氧化作用,采用沿面放電等離子體發(fā)生裝置,探究了放電電壓、曝氣量、曝氣氣體溫度以及亞硫酸鈣漿液的濃度和溫度等參數(shù)對亞硫酸鈣氧化率的影響。結(jié)果表明,在室溫條件下,當亞硫酸鈣濃度為0.01 mol/L時,放電電壓取15 k V、曝氣量取1.0 m3/h時具有較好的放電氧化效果;較低的曝氣氣體溫度和亞硫酸鈣濃度、以及較高的漿液溫度有利于亞硫酸鈣的放電氧化。當放電電壓為14 k V、亞硫酸鈣漿液初始濃度0.01 mol/L時,放電氧化僅采用0.7 m3/h曝氣量就可使其氧化率達到空氣自氧化采用1.4 m3/h曝氣量時的氧化率的1.49~1.59倍。當放電氧化的漿液濃度為空氣自氧化的2倍時,其氧化率為空氣自氧化的1.2~1.5倍,在降低工藝投資和運營成本方面具有明顯優(yōu)勢。
[Abstract]:In order to investigate the oxidation effect of ozone produced by plasma activated air on calcium sulfite in desulphurization slurry, the discharge voltage and aeration rate were investigated by using a surface discharge plasma generator. Effects of aeration gas temperature, concentration and temperature of calcium sulfite slurry on oxidation rate of calcium sulfite. The results show that at room temperature, when the concentration of calcium sulfite is 0.01kV, the discharge voltage is 15kV and the aeration rate is 1.0m3 路h, the discharge oxidation effect is better. Lower aeration gas temperature, calcium sulfite concentration and higher slurry temperature are beneficial to the discharge oxidation of calcium sulfite. When the discharge voltage is 14 kV and the initial concentration of calcium sulfite slurry is 0.01 mol/L, The oxidation rate of discharge oxidation can reach 1.49 鈮，
