Study on the Spiral Fluidization Cleaning Particle Deposition Test in Heat Exchanger

  • 摘要: 螺旋流态化自动清洗技术是螺旋钢丝与液固流态化有机结合,实现对其进行在线自动防除垢、强化传热的目的。运用旋液流态化技术设计模拟试验方案,提出在流态化粒子进入换热管部分采用截面向上逐渐减小的倾斜挡板结构,有效的解决流态化粒子在换热管内分布均匀问题。采用流量分别为8.8 m3/h、10 m3/h、12 m3/h进行试验,观察平均直径为3 mm的粒子在进口处的分布情况,测量各换热管的流动速度分布,优化换热管中流态化粒子均匀分布的管箱结构,流化态粒子的平均沉降速度为0.3~0.4 m/s,得到实现流态化粒子自然循环、在高速情况下的液固分离目的结构。
