ABSTRACT:
An apparatus is provided for causing circulation within a large body of fluid, especially a fluid comprising long molecules, such as polymer chains. The apparatus comprises a so-called "large bubble" generator, which generates a gas bubble to push the liquid through a series of bent pipes and ultimately into a vertically extending stackpipe. Upon generating a large gas bubble into the stackpipe, the gas acts as a piston within the stackpipe, pushing liquid upwardly therethrough, and thereby drawing liquid into the bottom. In order to prevent "motoring", a sharp-edged baffle plate is provided at a bend in the pipes between the gas-accumulator and the stackpipe. The baffle plate serves to prevent continuing flow of the fluid created by the presence of the long chain molecules.
