摘　　要：某氧化铝厂采用一种专利技术流化床冷却器,改变冷却排管结构和冷却水流程,采用冷却后的蒸发回水作为循环冷却水,回收高温段Al_2O_3的热量,可有效解决气体悬浮焙烧炉流化床冷却器存在的循环水冷却热量没利用、管内壁结垢严重、流化床冷却器冷却面积不够、出料温度较高等问题,并能取得经济效益145万元/年,节约标准煤16 157 t/a。A patent technology of fluidized bed cooler is used in a alumina plant, the structure of cooling exhaust pipe and flow of cooling water is changed, using after cooling evaporative water as circulating cooling water to recover the high-temperature of A1203 , this process can effectively solve the problems of circulating water cooling heat without effective used, tube wall sealing seriously, fluidized bed cooler area is not enough, and high discharge temperature, and can obtain a economic benefits of 1 450 000 yuan per year, and can save 16157 tons of SCE per year.
