<p><P>PROBLEM TO BE SOLVED: To significantly reduce energy necessary to dissolve a given amount of gas into a liquid of a unit mass by making diameters of bubbles smaller than those in conventional stationary diffusers. <P>SOLUTION: The bubble diffuser for diffusing bubbles in liquid is provided with: a diffuser part 28 with a vane-like cross section, disposed at an upper part of a diffuser tank 12 and dipped in liquid 16 in the diffuser tank 12, and diffusing introduced gas into liquid as bubbles through diffusing holes 38a provided on the surface; partition plates 52 placed under the diffuser part 28 and partitioning the inside of the diffuser tank 12 into multiple regions of E1, E2, E3; and a driving part 18 rotating or reciprocating vane chords of the diffuser part 28 in a roughly same horizontal plane by tilting them in relation to the horizontal plane, to generate fluidization having a vertical speed component to the liquid in the diffuser tank 12. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
