れる。DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view for explaining the overall position of the present invention. In FIG. 1, an untreated exhaust gas A from an inlet flue 1 has a cleaning liquid level 3 'when the gas is not passed at that pressure.
Is pushed down to the liquid level 3, passes through the lower end 6 of the partition plate 5, is subjected to the gas-liquid contact treatment with the cleaning liquid B, passes through the liquid level 4 on the exit flue 2 side, passes through the exit flue 2, and becomes treated exhaust gas A ′. Exhausted.
