Description
Technical field
The present invention relates to a kind of cooling towers of the dry and wet combined operating of gravity-flow ventilation, belong to circulating water technical field.
Background technique
For thermal power plant's host or the cooling tower of subsidiary engine circulating water, the common type of cooling has dry type and wet type two
Kind.Using air as cooling medium, carry out heat exchange with cold air by cooling triangle (heat exchange equipment) makes to follow dry cooling tower
The cooling of ring water, cooling procedure hardly consume water.The working principle of wet cooling tower is: water being sprayed on filler, sky is passed through
The mass transfer and heat transfer exchange process that gas and water generate make circulating water, and water consumption is very big.
Although dry cooling tower water-saving result is significant, at environment temperature higher (such as summer), the water temperature of recirculated water
The requirement (leaving water temperature is higher) for meeting generating equipment is tended not to, therefore the application of dry calibration is limited by very large.
The Chinese patent document of Publication No. CN 105403068A is " using gravity-flow ventilation and the dry and wet of combined running mode
Joint cooling tower and its application " discloses a kind of dry and wet joint cooling tower technical solution of gravity-flow ventilation, can make up dry cold
But the higher deficiency of summer leaving water temperature of tower.But in the technical scheme, mutual in order to avoid dry and cold section and clammy section
It influences, dry and cold section is disposed in clammy section of top, i.e., the height of dry and cold section bottom should be at least above the height of clammy section of water distribution system
Degree.Since dry and cold section of installation site is high, the difference in height that dry and cold section of cooling triangle (radiator) exports away from tower body is small, dry and cold section of fortune
Row draft is also small (it is related to the difference in height i.e. effective height that radiator is exported away from tower body that gravity-flow ventilation is formed by draft)；
Therefore, there is also the dry and cold section of problems that power output is small, cooling efficiency is low for the technical solution.
