Document Type and Number:
WIPO Patent Application WO/2020/070912
Kind Code:
A1
Abstract:
A gas liquid mixing nozzle is provided with: an inlet section for inflow of a gas and a liquid, the inlet section having a prescribed first internal diameter and comprising an annular contracting end face for contracting the internal diameter of the flow channel to less than the first internal diameter; a tubular throat section, which is connected on the downstream-side of the contracting end face, has a second internal diameter that is smaller than the first internal diameter, and has length in the direction of the central axis; and an outlet section, which is connected on the downstream-side of the throat section, comprises an annular expanding end face for expanding the internal diameter of the flow channel, and has a third internal diameter that is larger than the second internal diameter. In a cross-section comprising the central axis, the angle formed by the contracting end face is 180° and the ratio of the length of the throat section to the second internal diameter is at least 15.
