硅钢连续退火机组的节能措施
针对硅钢连续退火机组的主要能源介质消耗现状,对现有生产工艺和设备研究采取机组循环用水、增加清洗段漂洗级数等措施可节约大概27 m3/h的过滤水量,并可减少78%的弱碱处理量;将炉子烟气换热系统增加一级余热回收,每年回收的余热相当于583 t标煤消耗,可节约蒸汽5 368 t。 The present situation of energy consumption for silicon steel annealing line is analyzed in this paper.In existing process and equipment conditions,increasing the number of cleaning series will lead to a saving of about 27 m3/h of filter water and reduce 78 % of weak base processing volume.For the flue gas heat-exchange system,adding a waste heat recovery device will recover waste heat equivalent to 583 tons of standard coal per year,corresponding to a saving of steam 5 368 t per year.
