Abstract
Abstract Method of and arrangement for preventing the formation of clouds on wet cooling towers, according to which cooling water for cooling the substance to be cooled is passed in one direction over cooling insert means while cooling air is passed in opposite direction in counter current flow thereto and in heat exchange therewith for cooling said water, the thus obtained exhaust air of the cooling tower and prior to leaving the latter being intermixed with a separately heated-up gaseous medium.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A wet cooling tower system for preventing the formation of clouds thereon, which includes; a wet cooling tower with cooling insert means and with inlet means for admitting cooling water, air inlet means associated with said cooling tower for admitting cooling air thereto, said cooling tower also being provided with exhaust means for discharging exhaust air from said cooling tower, indirect heat transfer means having inlet means for a surrounding gaseous medium and also having internal means for heating up said gaseous medium admitted thereto, and conduit means establishing communication between said heat transfer means and said exhaust means for admixing said heated-up gaseous medium from said heat transfer means with the exhaust air discharged from said wet tower into said exhaust means.
Claim 2
Dependent Claim
123 words
A wet cooling tower system for preventing the formation of clouds thereon, which includes; a wet cooling tower with cooling insert means and with inlet means for admitting cooling water, air inlet means associated with said cooling tower for admitting cooling air thereto, said cooling tower also being provided with exhaust means for discharging exhaust air from said cooling tower, indirect heat transfer means having inlet means for a surrounding gaseous medium and also having internal means for heating up said gaseous medium admitted thereto, and conduit means establishing communication between said heat transfer means and said exhaust means for admixing said heated-up gaseous medium from said heat transfer means with the exhaust air discharged from said wet tower into said exhaust means.
Claim 3
Dependent Claim
89 words
A wet cooling tower system according to claim 1, in which said heat transfer meAns is provided with inlet means for admitting the substance to be cooled and is also provided with outlet means for discharging from said heat transfer means the substance to be cooled, and which includes additional heat transfer means communicating with said outlet means for receiving therefrom the substance cooled in said first mentioned heat transfer means, closed circuit means being provided which have interposed therein said additional heat transfer means and said cooling tower.
Claim 4
Dependent Claim
72 words
