摘　　要：摩擦带电器的结构影响粉煤灰摩擦电选脱炭效率。建立了粉煤灰摩擦电选脱炭实验系统,以37~74μm粉煤灰颗粒为介质,在不同风量条件下,对摩擦棒3种不同分布特征的摩擦带电器进行了摩擦电选脱炭实验对比研究,以正、负极板上烧失量和脱炭率的分布情况为评价依据,获得了脱炭效果较好的摩擦带电器。The structure of the friction device affects fly ash triboelectrostatic beneficiation removing carbon efficiency.The experimental system was established to remove the carbon of fly ash with 37~74 μm ash particles as the medium.Under different air flow conditions,we made a comparative study for removing unburned carbon effect in three different friction devices according to average LOI and removing unburned carbon ratio of the positive and negative plates to get the best one.
