Abstract
Abstract This disclosure is directed to a pumping and mixing device through which fluids are circulated. The device comprises a tank with a mixing head which contains high energy mass exchange impinging nozzles and a jet pump through which fluids from the mixing head pass under the driving force of at least one centrifugal pump. With the centrifugal pump inlet pressure increased by the use of the jet pump, large quantities of gases (or less dense fluids) may be injected at a point between the jet pump and the centrifugal pump inlet while still having the centrifugal pump produce a high discharge head (i.e., no cavitation). The fluid from the centrifugal pump outlet may be divided into two streams. One stream is passed through nozzle devices into the tank and the other is passed back through the jet pump. The device and its method of operation may be illustrated by the process of clarifying aqueous solutions of sugar and dissolving sugar crystals in water.
