Key word: Assessment of design of cooling tower whole tower checks
Cooling tower is the auxiliary equipment that industry produces, serve for technological equipment. The composition that this decided to the size of cooling tower, type reachs a part must get used to the requirement of water system all and characteristic, also have only such, the cooling tower that the design gives just has its economy and the rationality that move.
The technological equipment that cooling tower serves each industry differs somewhat, see the reasonable change of cooling tower now from the difference of technological equipment. The target that place of civil and cooling tower serves is refrigeration machine, it is identical that it asks the water of cooling tower is warm, namely: The water that enter a tower is warm 37 ℃ , water giving a tower is warm 32 ℃ . What what differ is: The size of refrigeration machine is distinct, the cooling tower that distinct size matchs to be not measured with size water, the cooling water quantity of civil tower and other industry cooling water are measured the photograph is smaller. It is OK that this decided civil tower make it standard type tower, to improve beneficial result, the cent of applicable air temperature of civil tower became two class, namely: Southern design air temperature is 28 ℃ by wet ball temperature; North is 27 ℃ by wet ball temperature.
The technological equipment of power industry is turbine, its water lukewarm demand to cooling tower is to press the summer when 90% fraction, wen Buchao of water giving a tower gives 33 ℃ , water difference in temperature differs somewhat because of aircrew because of the ground. The cooling water generous that compares it with civil tower photograph is much, the generation set form a complete set that this decided to differ is different the cooling tower of size, the size of the cooling tower that same set matchs in different situation also should differ. It is with commonly used 200MW machine exemple, its cooling water is measured control for 36000t/h, in Beijing area (wet ball temperature is: 24.4 ℃ ) match nature of 4500 square metre ventilated and cooling tower. Similar unit is in the Great Harmony of Shanxi (wet ball temperature is: 19 ℃ ) need to match those who use a tower to drench water area needs 3000 square metre only. Shanxi and boreal Kyoto are located in north, be like what press civil tower only to differentiate standard, the cooling tower that Great Harmony is about to throw 1500 square metre more invests.
And metallurgy, oil, petro-chemical and the technological equipment differ in thousands ways of other industry domain, its are opposite not only the requirement difference with warm water is bigger, and the size that requires cooling water amount also each are different.
