Flue gas desulfurization equipment absorption liquid circulation system blockage / corrosion prevention equipment and flue gas desulfurization equipment

摘要

To provide an absorption liquid circulation system blockage and anticorrosion device of an exhaust gas desulfurizer which prevents blockage and anticorrosion of a spray nozzle and a circulation line and can stably continue operation, and an exhaust gas desulfurizer.SOLUTION: An absorption liquid circulation system blockage and anticorrosion device of an exhaust gas desulfurizer includes: an absorption column 10; a circulation pump 20 which pumps an absorption liquid stored in a liquid storage part 14 of the absorption column 10; a circulation line 30 which circulates the absorption liquid pumped by the circulation pump 20; a spray nozzle 40 which is connected to the circulation line 30 and blows out the absorption liquid in the absorption column 10; and an oxidant feeder 50 which feeds an oxidant to the liquid storage part 14, and includes an air introduction system 60 which guides air to the spray nozzle 40 which prevents the absorption liquid from blowing out.SELECTED DRAWING: Figure 1
