纳米疏水剂在生物质型煤中的应用

Application of Nano Hydrophobic Agent to Bio-briquette

为了对纳米疏水剂在生物质型煤中的应用进行研究,利用纳米疏水剂在生物制型煤改性过程中的3个影响因素:疏水剂用量、炭化颗粒原始水分和改性时间进行正交试验,并将改性生物质型煤与未改性生物质型煤进行抗压强度、干燥特性及干燥能耗对比分析。结果表明:生物质型煤最佳的改性条件为炭的原始水分7%、疏水剂用量16%、改性时间3 h,并且成型水分能够减少19%左右;改性生物质型煤的干燥时间缩短,干燥速率没有明显变化,干燥能耗降低;用纳米疏水剂改性后的生物质型煤的抗压强度略有提高。

The applications of nano hydrophobic agent in the biomass briquette were studied,utilized the three influence factors：carbon water,dredging agent consumption and modification time in the process of the nano hydrophobic agent was modified in the biomass briquette to design orthogonal test.The compressive strength,drying characteristics and drying energy of modified biomass briquette and unmodified biomass briquette were analysed through the experiment.The results show that：the optimal modified conditions of biomass briquette is carbon water 7%,dredging agent consumption 16%,modification time 3 h,and molding moisture can reduce about 19%; The drying time of modified biomass briquette is shortened,the drying rate did not change significantly,The drying energy consumption reduces; the compressive strength of modified biomass briquette improves slightly
