摘要
以Ambersorb600为吸附剂,甲苯为吸附质,在两级循环流化床吸附装置内进行了吸附特性的实验.采用PGM-7600型VOCs分析仪测量甲苯的浓度,得到两段循环流化床的压力和空隙率分布及浓度随床高的分布:研究了气体进口浓度和表观气速对吸附效率的影响.在实验条件下吸附装置效率为95%～98%.
A two-stage circulating fluidized-bed adsorber has been developed for Volatile organic compounds(VOCs) adsorption. Experimental research was conducted using Ambersorb 600 as adsorbent and toluene as adsorbate. PGM-7600, a type of photo-ionization detector, was used to measure and record the concentration of toluene. The pressure drop, voidage distribution and concentration distribution along the CFB riser were obtained. The influences of inlet toluene concentration and air flow rate on the performance of the adsorber were discussed. The adsorption efficiency is between 95% and 98% under the experimental conditions.
