Production of softened water equipment for boiler hot water systems

Softened water equipment for Guangzhou boiler hot water systemThe principle:

Due to the fact that the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resins (water softeners) are generally used to replace Ca2+and Mg2+(the main components that form scale) in water. As the Ca2+and Mg2+in the resin increase, the efficiency 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 rinse the resin layer with saline solution in the salt tank, replacing the hardness ions on the resin. The resin is then discharged from the tank with the regeneration waste liquid, and the softening exchange function of the resin is restored.

Softened water equipment for Guangzhou boiler hot water systemThe workflow:

workThere are five processes: water production, backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All processes of different softening water equipment are very similar, but there may be some additional processes due to differences in actual processes or control needs. Any softening water equipment based on sodium ion exchange is developed on the basis of these five processes (among which, the fully automatic softening water equipment will increase the saltwater re injection process).

Backwash:After working for a period of time, the equipment will intercept a lot of pollutants brought by the raw water on the upper part of the resin. After removing these pollutants, the ion exchange resin can be exposed and the regeneration effect can be guaranteed. The backwashing process is when water is washed in from the bottom of the resin and out from the top, which can wash away the dirt intercepted at the top. This process usually takes about 5-15 minutes.

Salt absorption(regeneration)：The process of injecting salt water into the resin tank involves traditional equipment using a salt pump to inject salt water, while fully automatic equipment uses a built-in sprayer to suck in salt water (as long as the inlet water has a certain pressure). In practical work, the regeneration effect of salt water flowing through the resin at a slower speed is better than simply soaking the resin in salt water. Therefore, softening water equipment adopts the method of slow flow of salt water through the resin for regeneration, which generally takes about 30 minutes. The actual time is affected by the amount of salt used.

Characteristics:

1. The operating cycle and salt intake of the equipment can be adjusted according to the hardness of the raw water. The resin consumption is low, the salt consumption is low, the water quality is excellent, the operation is simple, and the maintenance is convenient.

2. The equipment has strong applicability and can withstand high hardness ≤ 30mmol/L with a residual hardness of less than 0.03mmol after one-time softening

3. The water production process is excellent, using a floating bed counter current regeneration process, with stable water quality and production, continuous water production, and softening hydration salt, regeneration, and cleaning.

4. Save salt and water. The specific consumption of recycled salt is 75-90 grams per gram equivalent, which is lower than similar imported equipment; Self consumption of water is low, accounting for only 2% -4% of the equipment's water production.

5. Long service life, due to the reasonable design of the valve structure, the service life of the automatic switch is doubled compared to the original one.

6. The equipment is lightweight, occupies a small area, does not require factory buildings or civil engineering, and has low installation, operation, and maintenance costs.

7. Easy to install, just connect the inlet and outlet pipes and power supply to start running. The automation level of equipment has been improved, achieving unmanned operation
