摘要：
Aim at improvement leaching reaction and heat transfer efficiency, A novel self-stirring tubular reactor driven by pressure energy used in bauxite digestion process was presented originally by Northeastern University, which combined the advantages of autoclaves and conventional tubular digestion equipment. Quasi-logarithmic equation between the stirring speed and the various factors was established by dimensional analysis method. The results demonstrated that higher pressure promoted the appearance of more obvious turbulence and improved the mixing effect of media in the reactor. The quasi-logarithmic equation between the stirring speed and the various factors was: N = 356.7053 rho(-0.43227) mu(-0.13546) P-0.56773 H-0.86454.
