The utility model has the beneficial effects that：（1）Middle part increases gas and water separator inside air cooling tower, plays following several
Big main function：Air cooling tower epimere desalted water and hypomere recirculated water are separated as desalination water collecting device, prevent air cooling tower by a
Calcium ions and magnesium ions fouling and clogging equipment and pipeline in epimere cryogenic freezing water system；B makes air cooling tower hypomere high temperature as gas passage
Gas, which can smoothly enter into epimere, to be continued to cool down；C is more when epimere desalted water liquid level is more than setting value as desalted water overflow port
Remaining desalted water can overflow in air cooling tower hypomere recirculated water.
（2）Increase a liquid seal trough for preventing from collaborating outside air cooling tower, the chilled water after heat exchange is led into water using pressure difference
The cold of the cold dirty nitrogen of tower recycling, chilled water-circulating pump boosting are sent after the further cooling of freezing unit and are followed at the top of air cooling tower again
Ring uses, and realizes desalted water closed cycle；
（3）The saturated vapour pressure of water is different under different temperatures, the high temperature washed by recirculated water come from air cooling tower lower part
Gas is desalted water cooling on air cooling tower top, and which part water vapour condenses the moisturizing as Desalting Water System, ensure that pre-
The water quality of cooling system chilled water solves the problems, such as chilldown system Crystallization Plugging caused by the raising of calcium ions and magnesium ions content in chilled water；
（4）Air cooling tower lower part high-temperature gas still uses circulating water cooling, reduces the load and energy consumption of freezing unit.Project
After implementation, after use for many years, each parking checking handpiece Water Chilling Units evaporator tubulation, chilled water pipeline, air cooling tower distributor
Do not occur crystalline polamer, transformation has reached design object and effect, achieved huge economic benefit.
