軟化水設(shè)備是用于降低水硬度的設(shè)備，主要除祛水中的鈣、鎂離子。軟化水設(shè)備在軟化水的過程中，不降低水中的總含鹽量。在熱水鍋爐系統(tǒng)、熱交換系統(tǒng)、工業(yè)冷卻系統(tǒng)、中央空調(diào)系統(tǒng)以及其他用水設(shè)備系統(tǒng)中都有廣泛的應(yīng)用。
Softening water equipment is used to reduce water hardness equipment, mainly removing calcium and magnesium ions in water. In the process of softening water, the total salt content in water is not reduced by softening water equipment. It is widely used in hot water boiler system, heat exchange system, industrial cooling system, central air conditioning system and other water equipment systems.
工作原理
Working Principle
由于水的硬度主要由鈣、鎂形成及表示，故一般采用陽離子交換樹脂(軟水器)，將水中的Ca2+、Mg2+（形成水垢的主要成份）置換出來，隨著樹脂內(nèi)Ca2+、Mg2+的增加，樹脂去除Ca2+、Mg2+的效能逐漸降低。
當(dāng)樹脂吸收一定量的鈣鎂離子之后，就必須進行再生，再生過程就是用鹽箱中的食鹽水沖洗樹脂層，把樹脂上的硬度離子在置換出來，隨再生廢液排出罐外，樹脂就又恢復(fù)了軟化交換功能。
由于水的硬度主要由鈣、鎂形成及表示由于水的硬度主要由鈣、鎂形成及表示鈉離子交換軟化處理的原理是將原水通過鈉型陽離子交換樹脂，使水中的硬度成分Ca2+、Mg2+與樹脂中的Na+相交換，從而吸附水中的Ca2+、Mg2+，使水得到軟化。
Because the hardness of water is mainly formed and expressed by calcium and magnesium, cationic exchange resin (water softener) is generally used to replace Ca2+, Mg2+ (the main component of scale formation) in water. With the increase of Ca2+, Mg2+, the removal efficiency of Ca2+, Mg2+ by resin decreases gradually.
When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The process of regeneration is to wash the resin layer with salt water in the salt box and replace the hardness ions on the resin. With the regenerated waste liquid discharged from the tank, the resin resumes the softening exchange function.
