摘　　要：吸气浮选机中的流体流动状况是影响吸气浮选机除油效果的关键因素。在四级吸气浮选机模拟装置上，用定性观测和定量测定手段研究了浮选机的流体流动状况，并选择合适的流动模型对浮选机中的流动进行了描述。研究发现，每个浮选室中的流动接近于理想全混流，上部混合较差；底部有很小量的短路流。各浮选室间有较大的返混流，在各浮选室人口加挡板，可有效地阻止短路流，减小各室间的返混流量。该研究结果可用于吸气浮选机的设计和改进。The flow performance of induced-air flotation machine is a key factor thataffects its efficiencv of oil removal. The flow performance of inducedair flotation machine isstudied with the qualitative method in the simulated four-stage flotation machine,The flowpattern suitable for the performance of flotation machine is suggested.The resul ts show thatthe flow pattern of every flotation chamber is close to the well-mixed flow. The flow is notfully mixed at the upper part of the flotation chamber,and small short-circuit flow exists atthe bottom of the flotation chamber.There is a large back-mixed flow between the flotationchan1bers,The plate fitted on the inlet of the flotation chamber can stop the short-circnit flowand lessen the backmined flow between the flotation chambers.
