The commonly used method of selecting cooling tower packing is to save energy, reduce consumption and reduce labor. 1. The height from the top of the packing to the lower edge of the suction section of the fan should be controlled to be equal to or greater than 0.2 times the diameter of the fan in the square cross-flow cooling tower. 2. The height of the airflow shortening section between the top surface of the counter-flow cooling tower packing and the inlet of the air duct should conform to the following rules: 1) When the top cover of the tower is flat, the top angle of the airflow shortening section calculated from the top of the packing should be Less than 90°; when there is a diversion ring (umbrella) under the flat top cover, the top angle of the airflow shortening section from the top surface of the water collector can be selected from 90° to 110°. 2) When the tower top cover plate is shortened from the water collector, the top angle of the shortened section cover plate should be selected from 90° to 110°. 3. The water filling of the cross-flow cooling equipment
should have a shortened inclination to the straight central axis of the tower from the top to the bottom. The shortened inclination angle of the drip-type water-spraying filler should be 9°～11°; the shortened inclination angle of the film-type water-spraying filler should be 5°～6°. 4. The counter-flow cooling tower with air intake from both sides should be equipped with a central air baffle, the upper edge of the partition is 200-300mm away from the bottom of the packing support beam, and the lower edge extends below the water surface of the tower's sump. 5. The cross-flow cooling tower should be set up to avoid short-circuit flow of air from the bottom of the packing to the water surface.
