APPARATUS AND METHOD OF DELIVERING A FLUID USING A NON-MECHANICAL EDUCTOR PUMP AND LOCK HOPPER
First Claim
1. An apparatus for delivering a fluid comprising:
- a lock hopper coupled to an eductor motive fluid inlet, a source of a treatment material and a suction flow outlet, the lock hopper configured to contain therein a pressurized treatment fluid as an output suction flow; and
an eductor pump assembly coupled to said lock hopper and comprising;
a suction chamber coupled to said lock hopper, the suction chamber in fluidic communication with the eductor motive fluid inlet, the suction flow outlet and a fluid mixture outlet, the suction chamber configured to output a fluid mixture;
a mixing chamber coupled to said fluid mixture outlet and configured to mix the fluid mixture therein; and
an expansion feature coupled to said mixing chamber and configured to expand the fluid mixture therein for delivery to a downstream component.

Abstract
An apparatus and method for delivering a fluid using non-mechanical lock hopper eductor assembly. The assembly including at least one lock hopper coupled to an eductor motive fluid inlet, a source of a treatment material and a suction flow outlet. The lock hopper configured to contain therein a pressurized treatment fluid as an output suction flow. The lock hopper is coupled to an eductor pump assembly. The eductor pump assembly including a suction chamber in fluidic communication with the eductor motive fluid inlet, the suction flow outlet and a fluid mixture outlet. The suction chamber configured to output a fluid mixture to a mixing chamber coupled to said fluid mixture outlet and configured to mix the fluid mixture therein. The eductor pump assembly further including an expansion feature coupled to said mixing chamber and configured to expand the fluid mixture therein for delivery to a downstream component.
