Why has it been emphasized that the steam boiler must be treated with softened water?

When you purchase steam boilers, you must have heard a suggestion from many boiler business personnel: equip the boiler with softened water treatment equipment. Why do business people emphasize water softening equipment many times? Let Zhengzhou Fangkuai boiler manufacturer tell you the answer.

First of all, we need to have a simple understanding of water softening equipment. Water softening equipment for steam boilers can also be called full-automatic sodium ion converters using ion exchange principles to remove calcium, magnesium and other scaled ions in the water. When the raw water containing hardness ions passes through the resin layer in the AC, the calcium and magnesium ions in the water will be replaced with the sodium ions adsorbed by the resin. The resin adsorbs the calcium and magnesium ions and the sodium ions enter the water, thus flowing out from the AC. Water is softened water with hardness removed.

Because the hardness of water is mainly composed and indicated by calcium and magnesium, cation exchange resin (water softener) is generally used to replace the Ca2+ and Mg2+ (the main components of scale) in the water. With the addition of Ca2+ and Mg2+ in the resin, the resin The effectiveness of removing Ca2+ and Mg2+ gradually decreases. After the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt box to replace the hardness ions on the resin, and then discharge the resin out of the tank with the regeneration waste liquid. It has recovered its softening communication function.
