Title:
EXHAUST GAS DESULFURIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/121552
Kind Code:
A1
Abstract:
This exhaust gas desulfurization device comprises: an absorption column configured in such a manner as to cause gas-liquid contact of a cleaning liquid with an exhaust gas, the absorption column containing, in the interior thereof, a liquid pooling section in which the cleaning liquid is stored; and a gas-liquid mixing device containing a first spray nozzle configured such that the distal end thereof is inserted into an insertion hole formed in a first side wall of the absorption column, and a mixed fluid of the cleaning liquid and the oxygen-containing gas is sprayed from a first discharge port into the liquid pooling section. The first spray nozzle includes a cylindrical section, and a first fastening part provided to protrude from the outer periphery of the cylindrical section in a direction orthogonal to the central axis of the first discharge port. The absorption column further contains: a cylindrical protrusion section provided to protrude outward from the peripheral edge part of the insertion hole formed in the first side wall, along a direction tilted from the horizontal plane at an angle θ, where θ represents the tilt angle from the horizontal plane of the central axis of the first discharge port; and a second fastening part provided to protrude from the distal end of the cylindrical protrusion section along a direction that is orthogonal to the direction in which the cylindrical protrusion section extends, and configured so as to be fixed to the first fastening part by the fastening device.
