Document Type and Number:
WIPO Patent Application WO/2011/132512
Kind Code:
A1
Abstract:
Disclosed is a mixed-flow nozzle that can, with a simple device, prevent the deposition/accretion of oxides on the inner wall of a raw-water/air mixed-flow nozzle of a water treatment device. In the mixed-flow nozzle—to which an air intake port (3) is formed on the downstream side of a water-pipe coupling section (2) at one end of the nozzle, and to which a mixed-flow spouting port (4) that spouts a mixed flow of water and air as a jet flow is formed at the other end of the nozzle—a nozzle inner-wall cleaning means is provided that comprises a helical chain (11) that is affixed to the nozzle pipe wall downstream from the air intake port, extends to the vicinity of the mixed-flow discharge port (4), and is impinged by the mixed flow, contacting the inner wall of the nozzle by means of continuously moving within the nozzle in a whirling manner by means of force received from said mixed flow.
