介绍了沧州炼油厂 0 6Mt/a重油催化装置再生器旋风分离系统技术改造情况。改造后采用PV型高效旋分器 ,一、二旋及粗旋入口面积增加了 30 %～ 38% ,一旋入口线速由大于 30m/s降低至正常范围 ,减轻了设备磨损及催化剂的磨蚀 ,并提高了分离效率 ,催化剂单耗由 0 9～ 1 1kg/t降低至 0 4～ 0 6kg/t,取得了显著效果 The technical reformation of cyclone separation system of 0 6Mt / a heavy oil catalytic converter in Cangzhou refinery was introduced. After the transformation, the PV type highly efficient cyclone is adopted. The area of ​​the first and second rotary and coarse rotary entrances is increased by 30% -38%. The linear velocity of the first rotary entrance is reduced from more than 30m / s to the normal range, which reduces equipment wear and catalyst erosion , And increased the separation efficiency, the catalyst unit consumption from 0 9 ~ 1 1kg / t down to 0 4 ~ 0 6kg / t, and achieved remarkable results
