The adhesion splash bounces up during the generation process and has different heights and directions, so it adheres over a relatively wide area. These deposited splashes grow and solidify over time to form scales, causing problems such as unbalanced gas flow, increased pressure loss, and corrosion of the partition plate, causing gas to blow through from the corroded openings.

る。[Example] One embodiment of the present invention will be explained using FIGS. 1 to 4. FIG. 1 is an embodiment diagram for explaining the positioning of the present invention as a whole. In FIG. 1, the untreated exhaust gas A from the inlet flue 1 is at a pressure level of 3' of the cleaning liquid when no gas is flowing.
is pushed down to the liquid level 3, passes through the lower end 6 of the partition plate 5, undergoes gas-liquid contact treatment with the cleaning liquid B, exits from the liquid level 4 on the outlet flue 2 side, passes through the outlet flue 2, and becomes treated exhaust gas A'. However, part of the splash generated when the untreated exhaust gas A sneaks under the lower end 6 of the partition plate 5 and when the treated exhaust gas A' escapes from the liquid level 4 is generated on the inlet side surface 7 and the outlet side of the partition plate 5, respectively. It adheres to the surface 8. In order to wash away the deposited splash, an opening 10 is provided on the inlet surface 7 of the partition plate.
and outlet side surface 8 are provided with fountains 9 facing each other. Cleaning water C is sent from the opening 10 of the water fountain 9 through the pipe 13 intermittently or continuously to the partition plate 5.
is injected toward the inlet side surface 7 and the outlet side surface 8 of. In addition, in the figure, 11 is a driver of the partition plate, and 12 is a seal.
