Title: AIR DIFFUSER FOR SEAWATER DESULFURIZATION AND SEAWATER DESULFURIZATION DEVICE PROVIDED WITH SAME
Abstract:
An air diffuser (30) for seawater desulfurization is provided with air diffusing tubes (34) that are disposed within an oxidation tank (13) for seawater desulfurization, bring the sulfur component in exhaust gas (22) into contact with seawater, and supply air to acidic mixed seawater (24) that includes seawater (23) that has absorbed sulfur and that has arisen because of seawater desulfurization and an air supply tube (33) that feeds air from the outside by an air introduction means to the air diffusing tubes (34). The hole diameter (d) of holes (35) in the air diffusing tubes (34) is 5 mm or greater. The pitch (P1) between holes (35, 35) in the air diffusing tubes (34) is 40 mm or greater, and the pitch (P2) between the air diffusing tubes (34, 34) disposed on the air supply tube (33) is 500 mm or greater.
