What are the basic principles of boiler softened water treatment equipment?

　　Boiler softened water treatment equipment can be used for steam boilers, hot water boilers, air conditioners, steam condensers, heat exchangers and other make-up water equipment.

　　It can also be used for the treatment of domestic water in hotels, restaurants, office buildings, apartments, etc., as well as for soft water treatment in industries such as beverages, brewing, chemicals, and pharmaceuticals.

　　The water softener uses strong acidic cation resin to replace calcium and magnesium ions in the raw water. The water flowing out of this equipment is softened water with extremely low hardness. Its chemical reaction is:2RNa Ca2 (Mg2)=R2Ca(Mg) 2Na . The resin is regenerated when it has adsorbed a certain amount of calcium and magnesium ions-Soak the resin in saturated brine to displace calcium, magnesium ions and other hardness substances in the resin, restore the resin's softening exchange capacity, and discharge the waste liquid. Its chemical reaction is:R2Ga=2RNa Ca2 . The entire regeneration process includes: backwashing-Loosen the resin layer and wash slowly by absorbing salt-An exchange reaction occurs, followed by rinsing (forward washing)-Wash away the calcium and magnesium ions exchanged during the chemical reaction and then fill with water-For the next generation.

　　Main technical indicators of the equipment

　　1. Inlet water pressure0.2~0.5Mpa

It can also be used for the treatment of domestic water in hotels, restaurants, office buildings, apartments, etc., as well as for soft water treatment in industries such as beverages, brewing, chemicals, and pharmaceuticals.

　　Time control and flow control

　　Fully automatic water softeners are classified into two types based on different regeneration control methods: time control and flow control.

　　▼Time control

　　Time control refers to the automatic initiation of the regeneration process when the equipment operation reaches the set regeneration time. This type of system sets the regeneration time based on the actual water consumption and the exchange capacity of the equipment. Users can select the regeneration process during periods with lower water consumption or start it manually at any time as needed.

　　The advantages of time control1The price is low.2Easy to operate

　　Disadvantages of time control:1Generally every24It can only regenerate once every hour.2The time point for regeneration cannot be precisely determined based on the actual usage conditions

　　Applicable occasions: Time-type control is generally applied in situations where the hardness is relatively low<4mmol/LThe water consumption is stable (the fluctuation in water usage does not exceed.15%In cases where the effluent quality requirements are not high and the water consumption is relatively small.

　　▼Flow control

　　Flow control is to set the operation endpoint based on the exchange capacity (total water production) of the equipment. When the equipment is in operation, a dedicated flowmeter is used to count the volume of water flowing out. When the total water output reaches the set water volume, the controller automatically starts the regeneration process. Before setting, the total water production for each cycle should be calculated based on the total resin filling volume and the hardness of the raw water, and then set according to this value.3900The water production volume of the series is automatically calculated by the controller. When the set water volume is reached, regeneration can be carried out immediately as needed or wait for a certain set time before regeneration.
