Advantages and disadvantages of closed cooling tower: 1. The whole pipeline system is closed-loop, and the circulating water is distilled water, which can make the heat exchanger and small pipeline of the vacuum furnace body free from scaling, pollution and corrosion, and the service life of the vacuum furnace is almost doubled. 2. Circulating water consumes almost no water, and the same type of equipment saves about 7000 tons of water every year.

Disadvantages of closed tower: the cost of closed cooling tower is three times that of open tower. (But the recycling value after ten years of sealing the tower is 8-65438+ 10,000, and opening the tower is almost worthless. )

Advantages of tower opening: 1. The cost of opening the tower is relatively low, which is one third of the price of closing the tower.

Disadvantages of tower opening: 1, 1-2 need to dig 20 cubic meters of underground pool. Due to head drop and open head loss, the power consumption is higher than that of closed tower, requiring two pumps, and the power consumption is high.

I bought 800 tons of Lingfeng closed cooling tower before, and summarized the above experience for your reference!
