A Study of Organic Calcium Salts Characteristics for SO2 and Nox Removal

, 2000
玉米秸秆等生物质废料快速热解产生的包含酸、酮、酚等多种有机物的热解液，与Ca(OH)_2混合可以制备比较廉价的混合有机钙盐，这种混合有机钙盐在钙硫比为1：1的条件下即可同时脱除SO_2和NO_x，是一种非常有前途的高温烟气净化剂。本文以与SO_2含量为2000～3000 ppm的模拟烟气反应1小时后的转化率来表征烟气净化剂的最大脱硫能力，利用微分固定床在730～940℃的温度范围内测定了混合有机钙盐的最大脱硫能力，并与其它净化剂进行了比较。几种净化剂1小时转化率平均值分别为：CaAc_2，91%；Ca ...

钢铁烧结烟气多污染物的排放特征及控制技术

, 2014
监测了钢铁烧结烟气的排放特征,发现SO_2排放浓度沿着烧结机方向呈现机头和机尾低、中部高的特点,二噁英的排放浓度与烟气温度正相关,温度高于250℃时二噁英的排放浓度出现峰值。调研了数十台烧结机的烟气排放特征,表明SO_2排放浓度≤2000 mg/m~3的占63%,要求脱硫效率大于90%;>2000 mg/m~3的占37%,要求脱硫效率大于96%。NO_x排放浓度≤300 mg/m~3的占86%,烟气无需脱硝可直接排放;在300?600 mg/m~3之间的占14%,要求脱硝效率大于50 ...
