Description: THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A method of imparting energy to a liquid stream carrying solid objects in a pipeline which comprises withdrawing liquid from said stream at one location only in the form of a plurality of circumferentially spaced outlets and injecting under pressure a plurality of jets of said withdrawn liquid into said stream at another location spaced upstream of said first location, each of said jets having a peripheral velocity component with respect to said stream and a direction of flow substantially the same as that of said stream and having substantially no radial velocity component whereby a swirling motion is imparted to said stream.

2. A device for imparting energy to a liquid stream carrying solid objects in a pipeline which comprises a plurality of liquid injection tubes each having an outlet in said pipeline, each said tube having an axis in tangential relation to said pipeline and in angular relation to the axis of said pipeline, each said tube having a radial angle of injection with said pipeline axis of approximately zero, a tank surrounding a section of said pipeline, said pipeline section having a plurality of circumferentially spaced liquid discharge openings downstream of said tube outlets and communicating with said tank, said tank having a liquid outlet leading therefrom and being otherwise imperforate, and a pump having a suction side connected to said tank outlet and an outlet connected to said tubes.

3.
