摘要
为解决低温等离子体(NTP)高压放电后产生的副产物排放问题,采用玉米芯吸附协同低温等离子体系统来降解硫化氢恶臭气体。确定了电极放电特性参数,考察NTP中的极间电压、H_2S初始浓度和吸附反应器(CA)协同对H_2S降解的影响;并分析H_2S降解机理。研究表明,CA协同NTP系统能显著提高H_2S去除效率,当采用负极放电、极板间距40 mm、极间电压15 k V、H_2S初始浓度为500×10^(-9)(ppb)、吸附时间60 min时,CA协同NTP去除H_2S的去除率可达到90%以上。
In order to overcome the discharge of byproducts for non-thermal plasma(NTP),corncob adsorption and non-thermal plasma system were presented for decomposition of H 2S.The effects on H 2S removal efficiency was investigated at characteristic parameters of electrode discharge,the interpolar voltage and the initial concentration of H 2S in NTP,and corncob adsorption(CA)coordination.The synergistic mechanisms of NTP and CA for H 2S decomposition were also analyzed.The results showed that H 2S removal efficiency could be significantly improved by CA synergistic NTP system,which up to 90%,when negative electrode spacing 40 mm,interelectrode voltage 15 kV,initial concentration of H 2S 500×10-9(ppb),and adsorption time 60 min.
