通过在煤浆中加入表面活性剂等有机溶剂,探讨了在微波加热条件下,表面活性剂和溶剂油等有机溶剂对细粉煤脱水效果的影响,着重讨论了不同浓度表面活性剂下微波作用时间及离子电荷性,以及微波作用下表面活性剂和溶剂复配对细粉煤脱水效果的影响,力求找出其中的脱水规律。结果表明:微波作用下的细粉煤脱水效果是明显的,同时,表面活性剂能够大大降低滤饼含湿量,而且阴离子表面活性剂的效果比阳离子好,柴油也能促进粉煤的脱水。 By adding organic solvents such as surfactants into coal slurry, the effects of organic solvents such as surfactant and solvent oil on the dehydration effect of fine coal coal under microwave heating were discussed. The effects of microwave irradiation with different concentrations of surfactants Time and ionic charge, as well as the influence of surfactant and solvent compounding on the dehydration effect of fine coal under the action of microwave, trying to find the law of dehydration. The results show that the effect of dehydration of fine coal under microwave irradiation is obvious. At the same time, the surfactant can greatly reduce the moisture content of filter cake, and the effect of anionic surfactant is better than that of cation. Diesel oil can also promote the dehydration of pulverized coal.
