Multi-pollutants simultaneous removal from flue gas

The multi-stages humidifier semi-dry flue gas cleaning technology, the CRS plasma flue gas cleaning technology and oxidative additive flue gas cleaning technology were investigated for multi-pollutants removal. The semi-dry flue gas cleaning technology using multi-stages humidifier and additive can improve oxidation and absorption, and it can achieve high multi-pollutants removal efficiency. The CRS discharge can produce many OH radicals that promote NO oxidation. Combining NaOH absorption can achieve high deSO2 and deNO, efficiencies. It is fit for the reconstruction of primary wet flue gas desulfurization （WFGD）. In addition, using NaClO2 as additive in the absorbent of WFGD can obtain very high removal efficiency of SO2 and NOx.

中国杭州夏季相对湿度对难溶性的亚微米级气溶胶演化的影响（英文）

目的:研究湿度对气溶胶的影响。创新点:首次研究气溶胶中铵盐的存在形式,为研究相对湿度对大气中气溶胶的影响做了补充。方法:1.利用高分辨飞行时间气溶胶质谱仪采集的外场数据分析各组分时序浓度和粒径分布,并通过正矩阵因数分解模型进行来源解析。2.通过研究各种物质和解析的因子随湿度的变化,探讨湿度对气溶胶演化的影响。3.通过相关性处理探究铵在气溶胶中的存在形式。结论:在相对湿度大于60%时,湿祛除效应对有机物中的二次有机气溶胶及硫酸盐的影响较大,而硝酸盐受液相反应生成作用影响更大。湿度从低到高时,气溶胶中铵的存在形式由硫酸铵向硝酸铵过渡。
