Description

Technical Field

[0001] The utility model belongs to the technical field of coolers, and in particular relates to a water-saving and mist-eliminating device for a dry-wet combined closed cooling tower. Background Art

[0002] In the process of cold air cooling circulating water in the dry-wet combined closed cooling tower, the cold air becomes saturated hot and humid air after heat exchange with water inside the cooling tower. In the cold northern regions, when the dry-wet combined closed cooling tower is in operation in winter, the saturated hot and humid air is discharged out of the tower and mixed with the cold air. Due to cooling and condensation, a fog group containing many tiny liquid particle groups is formed.
