Abstract
Official abstract text for this publication.
A wet type exhaust gas desulfurization apparatus includes an absorption tower desulfurizing exhaust gas by causing the exhaust gas to come into gas-liquid contact with an absorbent, a spray mechanism spraying the absorbent into the tower, an oxidization mechanism provided in a bottom portion of the tower and supplying oxygen to the absorbent that accumulates inside the tower, a circulation mechanism feeding the absorbent from a discharge port formed in the bottom portion of the tower, to the spray mechanism, and a liquid ejection mechanism including a hydraulic nozzle ejecting liquid into the tower. In this apparatus, the oxidization mechanisms are provided with an interval in a horizontal direction relative to the discharge port. Furthermore, in the apparatus, the hydraulic nozzle is installed in the bottom portion of the tower and is provided at a location between the oxidization mechanism and the discharge port.
