Resin Trap Screen Element for Boiler Water Softener


The main function of the resin trap screen element is to retain the cation exchange resin in the boiler water softener, prevent the loss of the medium, and protect the downstream pump from being blocked by the medium.

Boiler softening equipment uses cationic resin to soften the source water. The main purpose is to allow the cationic resin to absorb calcium and magnesium ions (the main components that form scale) in the water, reduce the hardness of the source water, and perform intelligent resin regeneration.

Aiming at the long scale of boiler, a kind of raw water pretreatment device is introduced to remove calcium and magnesium ions in raw water and the factors leading to boiler long scale.

As the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (softener) is generally used to replace Ca2 + and Mg2 + (the main component of scale formation) in water. With the increase of Ca2 + and Mg2 + in the resin, the removal efficiency of Ca2 + and Mg2 + by resin gradually decreases.

When 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 tank, and replace the hardness ions on the resin. With the regeneration waste liquid discharged from the tank, the resin will resume the softening exchange function.
