摘　　要：介绍了水冷式滚筒渣冷却器的结构和工作原理。在试生产初期,渣冷却器出现进渣管变形爆裂、进渣口密封泄漏、冷却水进/出口漏水、出渣口漏灰等问题,采取针对性技术改进措施后设备运行正常。渣冷却器渣处理量达到24 t/h、进/出渣温度为845/176℃、进/出水温度25/56℃,节能减排效果显著。The structure and working principle of water-cooled rolling-cylinder type slag cooler are described.In the early stage of trial production,the cooler experienced some problems such as deformation and bursting of slag inlet tube,seal leaking at slag inlet nozzle,cooling water inlet and outlet leaking and dust escaping from discharge hole.Related improvements were made and the device operated normally.Slag processing capacity of the cooler reaches 24 t/h at slag in/out temperature of 845/176℃and water in/out temperature of 25/56℃,with remarkable energy saving and emissions reduction.
