介绍瓮福化工公司磷酸二氢钙生产背景和工艺流程,通过粉体流换热器技术与传统冷却技术的对比,选择粉体流换热器作为工艺冷却装置。介绍粉体流冷却器的工作原理、设计参数、设备参数。对试运行数据进行分析,表明粉体流换热器可有效控制出料温度40~45℃;与传统转筒冷却器相比,年节约费用14.4万元。
This paper introduces the production background and process of monocalcium phosphate from Wengfu Chemical Company. By comparing the technology of powder flow heat exchanger with the traditional cooling technology, powder heat exchanger is selected as the process cooling device. Describes the working principle of powder flow cooler, design parameters, equipment parameters. Analysis of the trial run data shows that powder flow heat exchanger can effectively control the discharge temperature of 40 ~ 45 ℃; compared with the traditional drum cooler, the annual cost savings of 144,000 yuan.
