摘要
以氧化镁和氢氧化钾作为吸附剂,研究固定式化学滤料吸附装置对硫化氢(H_(2)S)的动态吸附性能。分析了滤料粒径、温湿度和停留时间对吸附剂吸附H_(2)S性能的影响,确定了最佳的吸附条件,并对滤料的吸附容量进行评价。结果表明:减小滤料的粒径和延长停留时间都能提高滤料对H_(2)S的去除率,相对湿度为20%~90%时,化学滤料对H_(2)S的去除率达到最佳状态,滤料对H_(2)S的吸附容量达45%以上。
In this paper,the dynamic adsorption performance of hydrogen sulfide(H_(2)S)by magnesium oxide and potassium hydrox⁃ide as adsorbents in a stationary chemical media adsorption device was investigated.The effects of adsorbent media particle size,temperature and humidity,and residence time on the H_(2)S adsorption were analyzed to determine the optimal adsorption conditions and to evaluated the adsorption capacity of the filter media.The results show that smaller particle size of the filter media and lon⁃ger residence time can improve the removal efficiency of H_(2)S.The removal efficiency of chemical filter media reaches the maximum under relative humidity in the range of 20%~90%and the adsorption capacity of filter media reached more than 45%.
