ABSTRACT:
A system for continuously removing gases from a liquid initially subjects the liquid to a pressure drop and then injects the liquid into a toroidal chamber in which it is impelled into a hollow annular flow path of high surface area and velocity. The liquid is forced helically about the annulus to create internal cavitation, and entrained and dissolved gases are removed both during injection and cavitation by a suction vent at an interior region of the toroidal flow chamber. Liquid is ejected from the periphery of the toroidal chamber into the bottom of a settling chamber, also maintained under vacuum, such that gases rise to another suction vent at the top of the chamber. Degassed liquid in the settling chamber moves under gravity into the orbit of an adjacent centrifugal pump and is continuously fed out from the system into ambient pressure by a positive drive pump. In an advantageous exemplification of the invention, a toroidal flow impeller and centrifugal pump are mounted in adjacent relation on a common magnetically driven shaft from a coaxial motor which also drives a suction pump for the system.
