ABSORPTION TOWER FOR WET EXHAUST GAS DESULFURIZATION APPARATUS

摘要

PURPOSE:To reduce draft losses to obtain excellent desulfurization performances and to decrease electric power consumption by providing a gas-liquid distributor made up of grid plates having specific grid height and width in an introducing section for exhaust gases. CONSTITUTION:Exhaust gases introduced into the lower part of a tower 1 are brought into contact with absorption liquids sprayed from spray nozzles 2 provided in the upper section of the tower 1 to absorb sulfur oxides in the exhaust gases. And a gas-liquid distributor 12 made up of grid plates 13 having a grid height of 50 mm or larger and a grid width equal to the height of said grid or smaller is provided in an introducing section 5 for the exhaust gas. As a result, draft losses can be reduced and also excellent desulfurization performances can be achieved, resulting in decreased electric power consumption.
