Study on minimum starting energy of self-stirring reactor driven by pressure energy

Abstract

Stirring plays an important role in the metallurgical process. Enhancing the agitation of materials can strengthen the turbulence in multiphase flow, which can shorten uniform mixing time and reaction time. In order to improve leaching reaction and heat transfer efficiency, a novel self-stirring tubular reactor driven by pressure energy used in bauxite digestion process is presented originally by Northeastern University, which combines the advantages of autoclaves and conventional tubular digestion equipment. According to the principle of dimensional analysis, the dimensionless equation between input power and various factors is established, and it is corrected to obtain input power, through verified, the calculated values are basically consistent with the experimental results.
