Abstract:

The research of solid-liquid pressure leaching reactor is always a focus which is paid close attention to by academy and industrial. Under this trend a self-stirring reactor was proposed originally by the Northeastern University. High speed video t and PIV technology were adopted in this paper to research on agitation characteristics of new kind of self-stirring reactor. The results demonstrated: the agitation speed decreased first and then increased with the rise of liquid height, the stirring speed was the lowest which was 84 rpm at the datum; the whole flow field presented turbulence state; the stirring reactor successfully converted pressure energy to mechanical energy, the stirring promoted the mixed turbulence of fluid in the reactor.
