摘要： 针对当前混合澄清萃取槽存在的问题,提出了改进的新型混合澄清萃取槽.采用专业的流体力学数值模拟软件ANSYS/FLUENT,对新型萃取槽内流场情况进行了模拟研究.结果表明,在油水两相流速分别为0.22和0.11 m/s,混合室搅拌转速为800 r/min,澄清室搅拌转速为20 r/min时,与传统萃取槽相比,在搅拌作用下,新型萃取槽澄清室内桨叶附近的混合带更窄,两相分离效果更佳;混合室内桨叶上下方流场呈涡旋流,与六直叶涡轮桨搅拌特点相符.

Abstract: An improved box mixing/clarifying tank was proposed to solve the problem of mixing/clarifying tank. The flow characteristic was simulated and studied by ANSYS/FLUENT in the improved new type mixing/clarifying tank. When the speeds of oil and water are 0.22 and 0.11 m/s, respectively, the rotation speeds of mixing room and clarifying room are 800 and 20 r/min, respectively, compared with the traditional extraction tank, the mixed zone is thinner near the blades in the new mixing/clarifying tank, and the two-phase separation effect is better under stirring. The flow field is vortex flow near the blades in the mixing room, and this is agreement with the flow characteristic of rushton turbine.
