摘要/Abstract

摘要：

针对脱硫系统和除水装置建立水平衡模型,对陶瓷膜除水烟气消白工艺的水平衡分布进行计算。某 600 MW机组运行结果表明：排烟温度、负荷与除水装置捕水量呈正比;机组燃烧褐煤时,工艺补水量需求最小,除水装置捕水量远超工艺补水量;冬季为满足消白要求,除水装置捕水量更多;陶瓷膜脱水效率每提高10百分点,捕水量增加25 t/h,但烟囱出口处的烟气温度会下降,当脱水效率从10%提升至60%时,排烟温度下降14.28 ℃,烟羽抬升高度下降176.50 m。陶瓷膜除水装置烟气消白工艺在合适的条件下可有效降低脱硫系统水耗,对全厂节水具有至关重要的意义。

Abstract:

Water balance models for a desulfurization system and a water removal system were built to assess the capacity of ceramic membrane in water removal and wet plume eradication.The operation results of a 600 MW unit show that the exhaust gas temperature and unit load are directly proportional to the water captured by the water removal system.A boiler taking lignite as fire coal demands the least amount of process water supplement which is far exceeded by the water captured by the water removal device.To meet the requirement of wet plume eradication in winter,the captured water mounts up.The captured water increases by 25 t/h for every 10% increase in dewatering efficiency of the ceramic membrane,but the exhaust gas temperature at the chimney outlet will be lower.When the efficiency rises from 10% to 60%,the exhaust gas temperature falls by 14.28 ℃,and the plume rise height reduces by 176.5 m.In the proper condition,the plume removal technology of the water removal system can effectively reduce the water consumption made by the desulfurization system,which is of great significance to the overall water saving.

Key words: water balance, ceramic membrane, water removal system, wet plume eradication, water saving
