In the actual engineering, the model can be selected according to the suspension situation in water.
Preferably, a water mist absorber is arranged inside the shell and above the water distribution system. The water mist absorber is positioned above the water distribution system, can capture water drops in gas and increase the recovery rate of wastewater.
Preferably, a motor and a reducer are arranged outside the shell for controlling the fan. The motor and the speed reducer are positioned outside the shell, and the installation, the overhaul and the control are very convenient.
Preferably, a water collecting tray is arranged inside the shell and below the filler system, and the water collecting tray is a pull-type tray. The pull-type water collecting tray is convenient to take out and install.
Preferably, the outer part of the side edge of the shell is provided with an escalator, and the escalator extends from the ground to the top of the shell. The arrangement of the escalator facilitates cleaning and maintenance of the system by operators.
Preferably, feet are provided below the enclosure to allow the enclosure to be moved away from the ground. The shell is more favorable to dispelling the heat off the ground, can accelerate cooling.
Therefore, the utility model discloses following beneficial effect has: (1) the film type filler and the drip type filler are combined for use, so that the volume of the filler can be reduced under the same cooling capacity, and the blocking condition can be relieved; (2) the film type packing and the drip type packing are arranged at intervals, so that the film type packing and the drip type packing are more convenient to clean respectively and are not easy to block compared with the stacked film type packing and drip type packing; (3) the thin film packing layer and the drip packing layer are fixed by a bracket.
