されたネットリング９等により構成されている。FIG. 3 shows a cross section of a conventional washing tower. FIG.
As shown in FIG. 1, a washing tower 1 includes a tank 2 in which a washing liquid, for example, washing water is stored, and trays 3 and 4 provided above the tank 2 and having a number of small holes such as punched metal. The injection nozzles 5, which are respectively disposed above the receiving trays 3, 4,

Further, the dust is washed again by the washing water sprayed from the spray nozzle 6 in a shower form by the many net rings 9 which are raised and are piled up through the small holes of the receiving tray 4 and are washed. Are discharged from the outlet 1b. The washed-out dust is dropped onto the tank 2 together with the washing water. Thus, dust is removed to purify the air. The water in tank 2
It is circulated to the injection nozzles 5 and 6 by the pump 7 and used repeatedly. The water in the tank 2 is replaced at an appropriate time because dust and the like gradually increase and become dirty and the cleaning effect is reduced.

きない。However, in the above-mentioned conventional washing tower, a large number of net rings are piled up on each of the receiving trays 3 and 4 when the air pushed into the tower by the fan 8 has a positive pressure. 9 quickly passes through each net ring 9 having a small resistance without passing through a small hole having a large resistance, and is hardly agitated by these net rings 9; Since the dust in the atmosphere is simply washed away with the washing water to be removed, fine dust cannot be removed, and the washing efficiency is very poor. Further, it is difficult to remove the odor, and it is not possible to clean the atmosphere (gas) containing a bad odor or the like.

It is necessary to have a multi-stage structure such as a four-stage structure, so that the height is further increased, the installation place is restricted, and maintenance is difficult. Further, there is a problem that the washing tower is very expensive due to an increase in size.

The gas in the chamber is taken into the gas-liquid stirring / separating means together with the cleaning liquid in the first chamber, mixed and stirred, and further separated. When the gas is mixed and stirred with the cleaning liquid, the gas is washed to remove dust and the like contained therein. The gas separated from the cleaning liquid by the gas-liquid stirring / separating means flows into the second chamber due to the negative pressure of the second chamber. The gas flowing into the second chamber is exhausted to the atmosphere by a fan. The gas in the first chamber is washed by the gas-liquid agitation / separation means and flows into the second chamber, whereby the internal pressure of the first chamber decreases, and accordingly, the gas to be washed flows into the first chamber. As a result, dust and the like contained in the gas are favorably removed. The first room and the second room are in communication,
The cleaning liquid is always kept at the same volume, and the liquid surfaces of the cleaning liquid in both chambers are kept at the level of the gas-liquid stirring / separating means.
