A large bubble generator includes a cylindrical gas accumulator tank open at its bottom and having a top wall. An inverted siphon includes a vertical bubble discharge leg coaxial with the tank and projecting upwardly through the tank top wall, and a roughly circular tubular section extending from the bottom of the vertical leg downwardly and outwardly and through the lower part of the tank peripheral wall, and thence upwardly, and thence inwardly into registry with a port in the upper part of the peripheral walls of the tank. Gas supply pipe coupling nipples extend upwardly and outwardly from the upper part of the siphon curved section. The bubble generator is disposed in the lower part of a liquid immersed liquid circulator conduit and is supported by the conduit wall by circumferentially spaced radial struts extending upwardly and outwardly from the accumulator tank to the conduit wall.
A device for circulating a fluid in a body of said fluid comprising a vertically extending conduit having an upper discharge opening and a lower inlet opening submerged in said fluid body and a large bubble generator supported at the lower part of said conduit and comprising a gas accumulator tank having a peripheral wall, a top wall, and having an opening at its bottom, an inverted siphon including a vertically extending discharge tubular leg disposed within said tank and registering with an opening in said top wall and terminating in an upper bubble discharge opening directed into said conduit, a lower tubular leg extending from said gas discharge leg below the top thereof outwardly through said peripheral wall proximate the bottom thereof and an outer leg extending upwardly and inwardly into registry with an opening in said peripheral wall proximate the top thereof, and means for delivering a gas into said accumulator tank.
