摘要

利用由静态混合器、喷嘴和分气盒组成的新型布气装置在搅拌釜式反应器中诱导生成泰勒流

对反应器流动特性及反应特性进行了实验研究。结果表明

与常规搅拌釜式反应器相比

泰勒流反应器内物料流动更加接近于平推流流型

泰勒流的生成在反应器内构建出局部平推流区域

降低了物料返混程度。反应器反应性能因流动特性改变而得以增强

相同实验条件下

在泰勒流反应器中进行的蔗糖水解反应转化率比在常规搅拌釜式反应器中高出26.7%。在一定操作范围内

局部平推流区域和反应转化率均随搅拌转速或进气量的增加而增大。泰勒流反应器可简化为平推流区和全混流区并联的流动模型

推导出了反应转化率与平推流区域占反应器总体积比率之间的关联关系。

Abstract

A Taylor-vortex flow reactor was constructed by using a new type of gas distributor consisting of static mixers

nozzles and gas distributor box.Flow and reaction performance of the constructed Taylor-vortex flow reactor was studied experimentally.The results showed that different from conventional stirred tank reactors

fluid flow in Taylor-vortex flow reactor was more close to ideal piston flow.Taylor vortices created local piston flow areas in the reactor and depressed back mixing.Reaction performance of Taylor-vortex flow reactor was also enhanced

and under the same experimental conditions conversion rate of sucrose hydrolysis carried out in the Taylor-vortex flow reactor was 26.7% higher than that in the conventional stirred tank reactor.Within a specific operation range

local piston flow area would expand and reaction conversion rate would increase with increasing agitation speed or air flow rate.A flow model of the Taylor-vortex flow reactor was presented

and reaction kinetic correlations were deduced.
