| 摘 要： | 为解决低温等离子体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、H2S初始浓度和CA协同对H2S降解的影响,并分析H2S降解机理。研究表明,CA协同NTP系统能显著提高H2S去除效率,当采用负极放电,极板间距40mm,极间电压15KV,H2S初始浓度为500ppb,吸附时间60min时,CA协同NTP去除H2S的去除率可达到90%以上。

| Abstract: | In order to overcome the discharge of byproducts for non-thermal plasma, corncob adsorption and non-thermal plasma system was presented for decomposition of H2S. The effects on H2S removal efficiency was investigated at characteristic parameters of electrode discharge, the interpolar voltage and the initial concentration of H2S in NTP, and CA coordination. The synergistic mechanisms of NTP and CA for H2S decomposition were also analyzed. The results showed that H2S removal efficiency could significantly improved by CA synergistic NTP system, which up to 90%, when negative electrode spacing 40mm, interelectrode voltage 15KV , initial concentration of H2S 500ppb,and adsorption time 60min. |
