闭式冷却塔(也叫蒸发式空冷器、密闭式冷却塔或封闭式冷却塔)是将管式换热器置于塔内,通过流通的空气、管外喷淋水与管内循环水的热交换保证降温效果。由于循环水是管内闭式循环,其能够保证水质不受污染,很好的保护了主设备的高效运行,提高了使用寿命。外界气温较低时,可以停掉喷淋水系统,起到节水效果。随着国家节能减排政策的实施和水资源的日益匮乏,近几年密闭式冷却塔在钢铁冶金、电力电子、机械加工、空调系统等行业得到了广泛的应用。

Closed cooling tower (also known as evaporative air cooler, closed cooling tower or closed cooling tower) is to place the tubular heat exchanger in the tower and ensure the cooling effect through the heat exchange of circulating air, spray water outside the pipe and circulating water inside the pipe. Because the circulating water is a closed circulation in the pipe, it can ensure that the water quality is not polluted, protect the efficient operation of the main equipment and improve the service life. When the outside temperature is low, the spray water system can be stopped to save water. With the implementation of national energy conservation and emission reduction policies and the increasing shortage of water resources, closed cooling towers have been widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries in recent years.

佛山闭式冷却塔

闭式冷却塔常用的面板有镀锌板、镀铝锌板、镀镁铝锌板和不锈钢板这四类,前三种为基板+防腐层的设计。 那这几种材质的面板有什么区别呢?用哪种材质更好呢?

The common panels of closed cooling tower include galvanized plate, aluminum zinc plate, magnesium aluminum zinc plate and stainless steel plate. The first three are the design of substrate + anti-corrosion coating. What's the difference between these panels? Which material is better?

镀锌铝镁板180g

镀镁铝锌板有其优良的断、切口自我防腐修复能力,及其表面致密的原子层架构,适用于各类较恶劣的环境中,如海边项目使用,佛山万庆在此建议闭式冷却塔选择镀镁铝锌板材质。

Galvanized aluminum magnesium plate (180g)

Magnesium aluminum zinc plated plate has excellent self-corrosion and repair ability of broken and cut, and its dense atomic layer structure on the surface. It is suitable for all kinds of harsh environments, such as seaside projects. Foshan Wanqing hereby suggests that the material of magnesium aluminum zinc plated plate should be selected for the closed cooling tower.

镀锌板275g锌层)/镀铝锌板150g锌层)

在常规环境下(无酸碱),以锌层10g/年(镀铝锌板6g/年)的腐蚀进度来计算,该类板材可以防护25年,但因塔内部为潮湿环境,腐蚀速度加大,其使用年限将有所下降。

Galvanized sheet (275g zinc layer) / aluminized zinc sheet (150g zinc layer)

Under the normal environment (without acid and alkali), based on the corrosion progress of zinc layer 10g / year (aluminized zinc plate 6G / year), this kind of plate can be protected for 25 years. However, due to the humid environment inside the tower, the corrosion rate increases, and its service life will be reduced.

不锈钢板304/0Cr18Ni9

不锈钢板主要用于各类有酸碱气体产生的环境中,但不锈钢板含有的氯离子,在使用环境中如有氯离子就不可以选择304/0Cr18Ni9不锈钢板,而需要选择更高级别的不锈钢材料或钛材料,但其替换材料成本很高。

Stainless steel plate (304 / 0Cr18Ni9)

Stainless steel plate is mainly used in various environments with acid-base gas. However, for the chloride ion contained in stainless steel plate, 304 / 0Cr18Ni9 stainless steel plate can not be selected if there is chloride ion in the use environment, but higher-grade stainless steel material or titanium material needs to be selected, but the cost of replacing materials is very high.
