摘要
催化裂化提升管出口新型旋流式快分利用气固沿旋流头切向喷出时形成的强旋流实现快速的气固高效分离。在一套φ300mm×2000 mm的引风式装置上进行试验,采用智能型五孔探针测试仪和差压计分别对不带分流筒的上行式提升管旋流头、带分流筒的上行式提升管旋流头和下行式提升管旋流头在封闭罩中的流场和压力降进行了测试。在分析不同的旋流式快分结构对流场分布的影响规律基础上,提出了结构改进建议。
With the new type of vortex quick separator in FCC riser outlet, gas-solid flow spraying out at tangent line to vortex separator forms a strong vortex flow field, so solid particles can be separated efficiently from the gas. Experiment has been carried out in a device with φ300 mm x 2 000 mm under negative pressure. The flow field and pressure drop of up-flow riser vortex separator with and without distribution tube as well as the down-flow vortex separator in a sealed chamber have been measured with intelligent five-hole probe and pressure differential meter. On the basis of analyzing the influence rule of different vortex quick separator structure on flow field distribution, suggestions to improve the structure of vortex quick separator have been proposed.
