摘要
采用介质阻挡放电等离子体技术净化恶臭气体硫化氢。考察了电压、频率、硫化氢初始浓度以及停留时间对硫化氢净化效果的影响。结果表明,介质阻挡放电可以有效消除硫化氢污染,硫化氢净化率随电压、频率以及停留时间的增加而升高,随硫化氢初始浓度增加而下降。当电压≥19kV,频率为300Hz,停留时间为1.56s,硫化氢初始质量浓度为30.1mg/m3时,硫化氢净化率接近100%。
The dielectric barrier discharge plasma technology was applied to decompose the hydrogen sulfide so as to control malodor. The effects of voltage, frequency, initial concentration and retention time on removal efficiency of hydrogen sulfide were investigated. The results showed that hydrogen sulfide could be removed efficiently by the dielectric barrier discharge, and the removal efficiency increased with the rising of voltage, frequency and retention time, while the removal efficiency decreased with the rising of gas initial concentration. Under the operating conditions of voltage was ≥19 kV, frequency was 300 Hz, retention time was 1.56 s and inlet concentration of hydrogen sulfide was 30.1 mg/m3 , the removal efficiency of hydrogen sulfide approximated to 100%.
