ABSTRACT:
A compact, heavy duty mixer-reactor is described which features a double-stage mixing/reaction chamber, one stage being of wall-baffled design and the other being unbaffled. Said mixer-reactor operates with a unique, two-stage impeller having a different set of coextensive agitator blades within each of said stages. For example, the effective radii of the blades in said unbaffled stage are significantly larger than those of the blades in said baffled stage. In addition, other differences in shape and pitch of the respective sets of agitator blades are provided to give enhanced performance, particularly in mixing and reacting finely divided solids with gases. The subject apparatus delivers outstanding results in terms of expediting thorough mixing and promoting complete reactions between fine solids and gaseous reagents. These results are particularly noteworthy when treating non-Newtonian suspensions of solids and liquids (e.g. wet wood pulps and the like) with virtually insoluble gaseous reagents such as ozone, oxygen or mixtures thereof, which often require superatmospheric conditions in order to achieve satisfactory treatment.
