摘要:

为了克服单一低温等离子体(NTP)降解硫化氢(H2S)能耗高和副产物排放的问题,采用低温等离子体活性炭纤维(ACF)吸附两段式系统降解硫化氢,考察不同充电电压两段式系统与单一低温等离子体系统对H2S降解率及副产物的影响,分析低温等离子体与活性碳纤维协同降解硫化氢的机理.研究表明:两段式系统能够显著提高H2S的去除率、降低能耗、去除副产物,并能延长ACF的穿透时间,增加吸附反应H2S的容量.当气体流量达到11.8 m3/h、充电电压为6 kV时,两段式系统能使H2S的去除率提高15%,能耗节省26.5%,ACF能够有效地去除SO2和O3,在ACF穿透前气流出口检测不到污染物;当充电电压从3 kV升高到7 kV时,ACF的穿透时间延长2到16倍.

Abstract:

In order to overcome the high energy consumption and discharge of byproducts for decomposition of hydrogen sulfide with nonthermal plasma (NTP) alone, a twostage system of NTP and activated carbon fibers (ACF) was presented for decomposition of H2S. The effects of twostage system and single NTP system on H2S removal efficiency and byproducts were investigated at different input voltage. The synergistic mechanisms of NTP and ACF for H2S decomposition were also analyzed. The twostage system could remarkably improve the H2S removal efficiency, decrease the energy consumption and remove byproducts, while prolong the breakthrough time of ACF and increase the decomposition and adsorption capacity for H2S. The results showed that the two-stage system improved 15% of the H2S removal efficiency and reduced 26.5% of the energy consumption at 6 kV with a gasflow rate of 11.8 m3/h.The energy consumption of the two-stage system at 6 kV reduced 26.5%. ACF could remove the SO2 and O3, no SO2 and O3 were detected before the breakthrough time of ACF for H2S.The breakthrough time of ACF for H2S was prolonged from 2 to 16 times by NTP at the input voltage range from 3 to 7 kV.
