摘要
介绍了基于湍流粒子运动的管道内壁除锈和基于多相流的涂料喷涂的技术原理,计算得出旋风法的单次处理长度和其他主要工艺参数的适用范围,并以国内某核电站饮用水管道系统旋风法除锈为例,详细介绍了施工过程、设备组成、除锈工艺和处理效果。结果表明:基于多相流原理的旋风法管道防腐技术可以有效解决管道内壁的腐蚀问题,延长管道使用寿命。
The principle of rust cleaning and coating spraying based on turbulent particle motion and multiphase flow are introduced. The length of processed pipeline and the applicable scope of other key parameters were calculated. An example of the application in a domestic nuclear power plant showed the details of working process, equipment composition, rust removal process and final effect. The results show that cyclone anticorrosion technique is an effective method to solve the corrosion problem of inner pipeline and the service life of the pipeline can be extended.
