摘要

目的　研究带导流筒搅拌槽内循环流量的影响因素

优化搅拌桨型式 .方法　在直径为 0 .5 m和0 .8m的带导流筒的搅拌槽内

采用热示踪热响应法系统考察了搅拌桨型、叶轮雷诺数、导流筒直径和离底距离、静液位高度、列管设置及其流通面积对循环流量的影响 .结果与结论　优选出新的能产生更大循环流量的搅拌桨型式

得出各结构参数对循环流量准数的影响情况

Abstract

Aim\ To find out the factors which affect the circulating flux in an agitated tank with draft tube

and optimize the type of impeller. Methods\ The effects of impeller types

the Renolds number of impeller

diameter of draft tube

clearance between draft tube and the bottom of tank

liquid height

the tube numbers and the circulation area on the circulation flux were systematically investigated by thermo tracing system in a flat bottomed cylindrical vessel of 0.5 m and 0.8 m in diameter

equipped with a draft tube and modeling heat exchange tubes. Results and Conclusion\ A new type impeller which can improve the circulation flux in agitating tank is exploited. The effects of the different structure parameters on the circulation number are shown.
