中浓度煤浆制备气化水煤浆的工艺方法探讨

将中浓度煤浆制备成气化水煤浆的主要任务是降低平均粒径和提高煤浆浓度,添加粉煤制浆工艺、部分煤浆脱水后回掺制浆工艺和全部煤浆浓缩后制浆工艺是可供选择的三种工艺方法,其中全部煤浆浓缩后制浆工艺最为简单、经济。采用管道运输中浓度煤浆为煤化工用户提供气化水煤浆原料煤,可以摆脱传统运煤方式的缺点,更为环保、经济。

Discussion on Preparation of Coal Water Slurry for Gasification From Medium Concentration Coal Slurry

The main task of preparing coal-water slurry for gasification from medium concentration coal-water slurry is to reduce the average particle size and increase the coal slurry concentration,The process of adding coal powder to medium concentration coal slurry,the process of blending partial dehydrated coal slurry into medium concentration coal slurry and the process of concentrating all the coal slurry are three kinds of main methods.Among them,the process of concentrating all the coal slurry is the most simple and economic.The pipeline transport of medium concentration coal slurry for coal chemical users can get rid of the shortcomings of the traditional transport mode of coal,it is more environmentally friendly and economical.
