Embodiment Construction

[0045] heat exchanger parts

[0046] Referring now to the drawings, in which like reference numerals denote like elements, in figure 1 Vapor condensing type heat exchanger packs 10 are shown in . The heat exchanger component 10 consists of a number of sheets 12 bonded together to form a component of a first passage 14 and a second passage 16 with two different air flows. In a preferred embodiment, the two air flows enter the heat exchanger component 10 perpendicularly to each other and are kept separated from each other by the lamellae 12 .

[0047] Sheet 12 is a relatively thin synthetic resinous material configured to assist in condensing steam containing hot air flow from the cold air flow passing through passage 14 and transferring heat to passage 16 . In a preferred embodiment, the material is 0.005 to 0.040 inches thick and preferably 0.015 to 0.020 inches thick. The surface 18 may be textured to provide an extended surface area of ​​least resistance to the flow of th...

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

[0001] priority [0002] This application claims priority to U.S. Patent Application Serial No. 09 / 973733, filed October 11, 2001, entitled Air-to-Air Atmospheric Pressure Heat Exchanger for Condensing Cooling Tower Effluent, the disclosure of which is hereby Cited for reference. technical field [0003] This application generally relates to water recovery from a cooling tower effluent or other heat rejecting equipment. More particularly, the present invention relates to a method and apparatus for recovering water from cooling tower effluent to provide a clean water source, reduce cooling tower water consumption and / or reduce cooling tower plume. Background technique [0004] In steam-driven turbine power generation, burners are used to heat water to produce the steam that drives the turbine to generate power. In order to minimize the amount of clean water required in this process, the steam must be converted back to water by removing heat so that the water can be reused i...
