Conventionally, the treatment of odor contained in the garbage gas has been a problem. As a deodorizing treatment of garbage gas, a method and apparatus as shown in FIG. 7 have been proposed. This method / apparatus allows garbage gas to pass through a washing tower in a state where a washing solution such as water is sprayed,
This is a method and device for removing the bad smell in the garbage gas and releasing it into the atmosphere.

でなく、洗浄溶液が無駄に放出されてしまう。However, it has been difficult for the above-mentioned conventional method and apparatus to deodorize a large amount of garbage gas. That is, in order to increase the processing amount of garbage gas, the passing speed (wind and wind speed) of the garbage gas must be increased,
If this is raised, the residence time of the garbage gas in the washing tower is shortened, washing with the sprayed washing solution becomes insufficient, and sufficient deodorization becomes difficult. Also, when the garbage gas passage speed is increased, the particles are light in the atomized cleaning solution sprayed, so that the particles are flushed out together with the garbage gas, and the cleaning with the cleaning solution becomes insufficient. Instead, the cleaning solution is discharged wastefully.
