Description
Technical field
The utility model belongs to cooling technology field, the main auxiliary spike cooling system proposing a kind of compound closed cycle water cooling tower.
Background technology
China is a lack of water country, and freshwater resources are only 1/4 of world average level per capita, ranks 110 in the world, and be one of whole world country that water resource is the poorest per capita, available water resource is only 900 cubic metres per capita, and distributed pole is unbalanced.From China Statistical yearbook, national industrial water consumption in 2014 is 1,420 hundred million m
3, account for 22.83% of total water consumption, and account for 70% ~ 80% of industrial total water consumption as the cooling water of cooling medium.The cyclic utilization rate of China's water for industrial use is very low simultaneously, the comprehensive recycling rate of waterused of water in 2010 is only 67%, developed country generally reaches 85% ~ 90%, so the recycling rate of waterused improving water for industrial use particularly cooling water is great to alleviation shortage of water resources question meaning.
Cooling tower be can reach water recycle effect and one of cooling device be generally used.It utilizes air directly or indirectly to contact with high-temperature-hot-water, reduces water temperature, reaches the object recycling water for industrial use.According to the way of contact of circulation water and air, cooling tower can be divided into open type and enclosed two kinds.Most of cooling tower in present commercial Application is open cooling tower, the problems such as ubiquity cycle water is poor, water consumption is large, energy loss is large, operating cost is large.
Relative to open cooling tower, closed cooling tower is distributed in surrounding air by wall-type heat exchange by recirculated water heat, avoid recirculated water to contact with the direct of environment, in longtime running, do not have quantity of circulating water lose (ignoring system leakage reason) and reduce recirculated water pump head, achieve the object of saving water and energy.
Closed circuit cooling system generally adopts Air flow or vaporation-type cooling.And use the form of air cooling and evaporating cold compound (compound closed cycle water cooling tower) will more economically, regulate also more flexible than pure air cooling.According to making land used environmental condition and user's service requirement, compound closed cycle water cooling tower is when designing, generally can set a temperature of cutting off the water, namely when environment temperature not higher than this design cut off the water temperature time, compound closed cycle water cooling tower adopts absolutely dry operation, is reduced by circulating water temperature by Air flow; When environment temperature cuts off the water temperature higher than this design, open evaporating cold shower water, relying part divides low-quality spray evaporation of water to be taken away by recirculated water heat, reduces temperature, meets user's requirement.
But certain areas are due to the restriction of water saving index, require higher temperature of cutting off the water, the compound closed cycle water cooling tower equipment of independent employing standard can not meet temperature requirement of cutting off the water, or bring very large difficulty to equipment de-sign and manufacture, need the compound closed cycle water cooling tower design considering to meet higher temperature of cutting off the water.
