摘要
随着我国国民经济的发展,国民经济对水的需求量以惊人的速度增长,然而我国的水资源有限,许多城市缺水。为了有效解决目前经济发展和水资源短缺的矛盾,对国民经济提出了节水的要求。工业及城市用水的循环使用,就是一个很好的办法。在整个国民经济的用水中,冷却水使用占很大比例,因此如何解决冷却水的循环使用和冷却水的循环使用效率问题就破在眉睫。传统的干式冷却塔虽然解决了水的循环使用问题,但是其往往满足不了工艺的冷却要求。湿式冷却塔能够满足工艺的冷却要求,但是其水质难以得到保障。而干湿式冷却塔既解决了水的循环使用问题和水质问题,又满足了工艺的冷却要求,是一种新型冷却设备。
With the development of national economy,the demand for water in China has been increasing at an astonishing speed in recent years.However,China is a country with limited water resources and many cities are short of water.Water-saving is therefore necessary for the economic development,and recycling of process and service water is very important.Cooling water accounts for a large proportion of process water.It is thus of importance to solve the problem of cooling water recycling and improve the efficiency of recycling cooling water.The conventional dry cooling tower can be used to solve the problem of water recycling,but it frequently fails to meet the requirements of cooling process.The wet cooling tower can meet the requirements of cooling process,but it is difficult to guarantee the water quality at the same time.As a new type of cooling installation,the wet-dry cooling tower can meet both requirements of water recycling and the cooling process.
