The removal of toluene from waste gas by Honeycomb Adsorption Rotor with modified 13X molecular sieves was systematically investigated. The effects of the rotor operating parameters and the feed gas parameters on the adsorption efficiency were clarified. The experimental results indicated that the honeycomb adsorption rotor had a good humidity resistance. The removal efficiency of honeycomb adsorption rotor achieved the maximal value with optimal rotor speed and optimal generation air temperature. Moreover, for an appropriate flow rate ratio the removal efficiency and energy consumption should be taken into account. When the recommended operating parameters were regeneration air temperature of 180 degrees C, rotor speed of 2.8-5 r x h(-1), flow rate ratio of 8-12, the removal efficiency kept over 90% for the toluene gas with concentration of 100 mg x m(-3) and inlet velocity of 2 m x s(-1). The research provided design experience and operating parameters for industrial application of honeycomb adsorption rotor. It showed that lower empty bed velocity, faster rotor speed and higher temperature were necessary to purify organic waste gases of higher concentrations.
系统研究了采用改性13X分子筛的蜂窝吸附转轮去除废气中甲苯的情况。阐明了转轮运行参数和原料气参数对吸附效率的影响。实验结果表明，蜂窝吸附转轮具有良好的耐湿性。蜂窝吸附转轮在最佳转速和最佳再生空气温度下，去除效率达到最大值。此外，对于合适的流量比，应综合考虑去除效率和能耗。当推荐运行参数为再生空气温度180℃、转轮转速2.8 - 5 r·h⁻¹、流量比8 - 12时，对于浓度为100 mg·m⁻³、入口流速为2 m·s⁻¹的甲苯气体，去除效率保持在90%以上。该研究为蜂窝吸附转轮的工业应用提供了设计经验和运行参数。结果表明，净化高浓度有机废气需要较低的空床流速、较快的转轮转速和较高的温度。
