SCRUBBER FOR AN APPARATUS FOR THE DESULFURIZATION OF FLUE GAS

摘要

A scrubber for the desulfurization of flue gases in which the flue gas rises through the recirculated scrubbing liquid which can contain calcium compounds, has a liquid separator at the head of the column formed by a number of impingement baffle registers or units in an annular array. The gas collecting passage surrounding this array is provided with flaps or sliders as closure elements to isolate at least one segment of this passage and thereby accommodating the scrubbing to less than full gas loading.
