Air cooled water composite cooling tower

Abstract

Heat exchanger packs having a first set of passageways for receiving a stream of ambient air and a second set of passageways for receiving a stream of warm water laden air is disclosed. The first set of passageways and second set of passageways being separate and permitting the warm water laden air stream to be cooled by the stream of ambient air so that water can condense out of the warm water laden air stream. Cooling tower configurations including the heat exchanger pack are disclosed for achieving effluent plume abatement, and capture of a portion of the effluent for replacement back into the cooling tower reservoir or as a source of purified water.

Description

technical field

[0001] The invention relates to an air-cooled and cold-water composite cooling tower, which belongs to the application field of cooling devices. Background technique

[0002] At present, known cooling towers are two main forms of cold water type and air cooling type. These two cooling towers have natural draft cooling towers and mechanical draft cooling towers. Since the cooling tower is mainly affected by the wet bulb temperature of the air, it relies on the evaporation and conduction of water to dissipate heat, so its consumption of water is very large. The air cooling tower uses conduction to make the air absorb heat to achieve heat dissipation, which is mainly affected by the dry bulb temperature of the air. Due to the high dry bulb temperature of the air, small specific heat, limited heat absorption capacity, and low cooling efficiency, the air cooler needs to have a large surface area, making the air cooler expensive.
