Description
Technical field
This utility model relates to cooling tower energy regenerating and utilizes technical field, is specifically related to a kind of circulating water cooling tower overboard
Potential energy power generating system.
Background technology
Cooling tower is as the effective cooling device of one, in industrial and agricultural production in particular for a large amount of thermal power stations cooling down water
It is widely used with in nuclear power station therrmodynamic system.The most rare along with the development of power industry and water resource, people are to cooling
The requirement of tower cooler effect and cooling effectiveness also gradually steps up, and constantly studies the performance of cooling tower.
In conventional reverse-flow formula cooling stack, hot water is sent into tower interior-heat moisture disposition by pipeline by vertical tube vertical shaft
System, through sparge pipe again by spraying and splashing facility, is spread across water on filler;After filler, Cheng Yuzhuan free-electron model enters and catchments to bottom
Pond, the water after cooling is taken away and is reused.This style of cooling tower is referred to as being called for short conventional tower.
Owing to the cooling water of conventional tower is relatively big through the height i.e. rain belt of filler free-electron model, cause conventional tower height of delivery relatively
Height, therefore circulating pump head is higher, power is bigger.For reducing circulation power consumption, in 1970's Mo, by France's electricity
