Biological deodorization tower with pre-wetting and deodorization functions

The invention discloses a biological deodorization tower with pre-wetting and deodorization functions, and relates to the technical field of gas treatment.The biological deodorization tower is provided with a pre-wetting mechanism, input odor flow can be accelerated and then discharged through a Laval pipe, fan blades are driven to rotate through high-speed airflow, and therefore power can be provided for rotation of the pre-wetting mechanism; the multiple branch pipes can rotate in the second tower body, a power device does not need to be independently arranged for rotation of the pre-wetting mechanism, the cost for arranging the power device is saved, the structure is simpler, and follow-up overhaul and maintenance work is facilitated; secondly, when the branch pipe rotates, the clean water in the second tower body can be disturbed, so that the clean water and the odor discharged from the branch pipe are stirred and mixed, and the purpose of full contact of the odor and the clean water is achieved; moreover
