Article Preview

A new DSH type dynamic-static combined mixer, which combines the advantages of dynamic mixing agitator and SH type static mixer, with the structure of alternative connection of the turning impeller, liquid shunt unit and double-barreled helical stationary blade, is original designed by the author. The allotype impeller is driven by the two-phase flow and meanwhile the two-phase flow is sheared by the allotype impeller. The double helix eddy flow is formed out of two-phase flow by the stationary blade due to the shearing effect of allotype impeller which results in the improvement of mixture efficiency. The most characteristic of this design is: the mixture is driven by the dynamic force of liquid itself, therefore the energy is saved and the mixture efficiency is enhanced. Followed by the illustration of the structure, the preliminary analysis of the flow field is carried out, which provides some proofs for the selection and optimization of the static-dynamic combined high efficient mixer structural parameters.
