Title:
GAS-LIQUID MIXING DEVICE, AND GAS-LIQUID MIXING DEVICE-EQUIPPED EXHAUST GAS DESULFURIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/121553
Kind Code:
A1
Abstract:
This gas-liquid mixing device is configured to spray an oxygen-containing gas and a cleaning liquid into a liquid pooling section for storing a cleaning liquid in an absorption column that causes gas-liquid contact of the cleaning liquid and an exhaust gas. This gas-liquid mixing device comprises: a first cylindrical section having formed therein a cleaning liquid introduction port demarcating a first flow path in the interior thereof, for introducing the cleaning liquid into the first flow path, a gas introduction port for introducing a gas into the first flow path along a direction orthogonal to the flow direction of the cleaning liquid introduced from the cleaning liquid introduction port and flowing in the first flow path, and a discharge port discharging a mixed fluid of the gas and the cleaning liquid; and a constriction part provided more on the upstream side in the flow direction of the cleaning liquid than a flow-merging portion wherein the flow of the cleaning liquid introduced from the cleaning liquid introduction port and the gas introduced from the gas introduction port merge. When D1 represents the inner diameter of the discharge port, and D2 represents the inner diameter of the gas introduction port, the gas-liquid mixing device satisfies the condition: 0.5 < D2/D1 < 0.8.
