错流旋转填料床脱除细颗粒物研究
Research on removal of fine particles by cross-flow rotating packed bed
摘要
Abstract
Fine particles are dangerous to environment and mankind,and could not be removed by common dust separator. The rotating packed bed combines various dust removal mechanisms,and has high collection efficiency and low power consumption. A pilot-scale system was set up by using fly ash with average particle size of 2.25μm as fine particles and cross-flow rotating packed bed as wet scrubber in this paper. A method of measuring particle size distribution of dust and calculating the classification efficiency using Mastersizer was proposed. The system was investigated at different rotating speeds,liquid-gas ratios,and gas flowrates. Classification efficiency increased with increasing rotating speed and liquid-gas ratio,and removal efficiency could be up to 96%. These data provided strong support to industrialization of high gravity wet cleaning. Results of fitted regression of classification efficiency showed that correlation coefficient R was 0.9808. Classification efficiency of cross-flow rotating packed bed was higher than common wet dust collector and impact of particle size was less. Cross-flow rotating packed bed can be used to remove fine particles in gas and has broad application prospect.关键词
