摘要
介绍煤制氢装置用中水替代真空抽滤机新鲜水作为滤布清洗水的节能改造情况,实施后真空抽滤机运行状态良好、气化炉运行平稳、外排废水指标合格、煤浆质量稳定,新鲜水消耗降低,节能降耗效果显著。
This paper introduced the energy saving reformation in a hydrogen preparation plant with coal as its feedstock by using reclaimed water to wash the filter cloth instead of fresh water. After reformation, the filter remained in a good operation condition, the gasifier operated smoothly, discharged waste water was qualified as defined in the specification, the quality of coal slurry remained stable, and the consumption of fresh water reduced greatly.
