Title:
LIQUID PROCESSING NOZZLE, LIQUID PROCESSING METHOD USING SAME, GAS DISSOLUTION METHOD, AND GAS DISSOLUTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/195116
Kind Code:
A2
Abstract:
Provided is a liquid processing nozzle that exhibits very efficient generation of microscopic bubbles and excellent gas dissolution capacity. The liquid processing nozzle 1 is provided with: a nozzle body 2 having a liquid passage 3 formed therein; and a processing core CORE comprising protrusions 10 that protrude from the inner surface of the liquid passage 3 and that have, formed in the circumferential direction and on the outer peripheral surface thereof, a plurality of alternating contiguous ridge sections 11 and valley sections 12, the valley sections 12 serving as high flow rate sections. The effective valley point density (Ne/St) normalized by the entire flow cross-sectional area (St) is maintained at at least 1.5 parts/mm2. For the protrusions 10, the effective valley point density (Ne/St), which is the number (Ne) of effective valley points normalized by the entire flow cross-sectional area (St), is maintained at at least 1.5 parts/mm2.
