摘要
煤浆气化工艺中细渣压滤脱水采用新型隔膜板框压滤机,该设备运行电耗低,压滤滤饼含水率在35%~43%。在运行调试过程中,通过调节压榨压力、进料时间、反吹次数等保证滤饼含水率,优化滤液进料条件,延长滤布使用寿命,保证压滤装置稳定长周期运行。
A new kind of diaphragm plate-and-frame filter press was used to remove water from fine slag in coal water slurry gasification. Using this equipment,power consumption was lowered down,water content in filter cake remained between 35%~43%. During debugging,the readjustment on filter pressure,feeding time and back flushing time guaranteed the water content in filter cake,optimized the feeding condition of filter liquor, prolonged the life of filter cloth,and ensured a long term and stable operation of the equipment.
