中文摘要：

为了实现同时控制铅锌冶炼行业排放的汞（Hg）等重金属、二氧化硫（SO2）和氮氧化物（NOx）的目的,采用低温等离子体结合动力波湿法吸收技术对烟气中的单质汞（Hg0）、SO2和NOx进行了协同控制研究。首先利用低温等离子体放电技术研究了电压、氧气（O2）体积分数、污染物停留时间、Hg0初始质量浓度以及SO2和NO体积分数的变化对Hg0去除效率的影响,同时研究了电压以及SO2和NO初始体积分数对SO2和NO去除效率的影响,然后研究了低温等离子体结合动力波湿法脱除系统对Hg0、SO2和NO这3种污染物协同脱除的效果。结果表明,低温等离子体结合动力波湿法脱除系统对烟气中Hg0、SO2和NO的排放可起到高效协同脱除的效果,其去除效率分别达到51.3%、98%和50.9%。该技术不仅适用于有色冶炼烟气多种污染物协同脱除控制,而且同样适用于燃煤烟气,对于实现煤化石能源的高效清洁利用具有重要巨大的应用前景和深远的现实意义。

英文摘要：

In order to control emissions of mercury （Hg）, sulfer dioxide （SO2）, and nitrogen oxides （NOx） from lead and zinc smelting industry, we researched the synergistic control of elemental mercury （Hg0）, SO2, and NOx using the non-thermal plasma （NTP） combined with dynamic wave wet absorption technology in flue gas. We studied the effects of voltage, oxygen volume fraction, retention time, initial mass concentration and SO2, NO volume fraction on Hg0 removal efficiency. Moreover, the influence of voltage and initial volume fraction on SO2 and NO removal efficiency were studied using the non-thermal plasma. The synergistic technology of NTP with dynamic wave wet absorption was adopted to study the removal efficiency of three pollutants of Hg0, SO2, and NO together. The synergistic removal efficiency of Hg0, SO2, and NO could reach51.3%, 98%, and 50.9% using NTP combined with dynamic wave wet removal system, respectively. A conclusion can be drawn that the application of this technology is suitable for not only a variety of non-ferrous smelting gas pollutants synergy removal control, but also coal-fired flue gas. It is important to realize the efficient clean utilization of coal and fossil energy, and has huge application prospect and far-reaching practical significance.
