摘要
为净化黄磷尾气中的主要废气PH3和H2S,利用高浓度CO气体对黄磷尾气进行了现场吸附净化实验;用气相色谱测定了尾气中主要气体物质的含量和吸附实验;给出了现场实验条件;进行了再生实验。结果表明:改性活性炭的净化效果要好于空白炭,吸附容量可达101.12mg/g;三次再生活性炭的磷容量降至80.65mg/g。
In order to remove PH3 and H2S in off-gas of yellow phosphorus and utilize high concentration CO, chromatography GC-14C was used to research content of component in yellow phosphorus tail gas and adsorption experiment analysis; Parameters of adsorption reaction was given; Regeneration activated carbon. Following results can be concluded： The purification efficiency of modified activated carbon is better than virgin carbon and phosphorus capacity is 101. 12mg/g; Phosphorus capacity of regeneration carbon drop to 80. 65mg/g.
