OXIDISING APPARATUS USED IN ABSORPTION TOWERS FOR DESULFURISATION OF FURNACE GAS AND METHOD OF OXIDISING PRECIPITATION PRODUCT IN SUCH ABSORPTION TOWER

摘要

The present invention is a method and apparatus for the oxidation of the bottom product of the flue gas leaving the sulfur absorber reaction. This bottom product is partially trapped and recirculated within the column, it is discharged to a separate tank adjacent to the oxidation tower. The liquid level in a separate oxidation tank is at a higher position than the level of the bottom product in the recycle tank of the absorption tower. As a result, after the oxidation in the oxidation tank, the bottom product is returned to the recirculation tank through the weir like.
