Working principle of softened water equipment

The calcium and magnesium ions in water are the main cause of scale formation when water temperature changes. At present, commonly used softening water equipment in China mainly includes manual, domestic combination, domestic multi valve, imported multi valve, etc. Among them, imported multi valve softening water equipment is widely used, mainly composed of imported multi valve and controller as the core, and equipped with resin tank, salt box, pipeline and other materials to form fully automatic softening water equipment.

Due to the significant impact of scale deposition on people's lives and production, both production water and domestic water have certain requirements for water hardness indicators. Especially if the boiler water contains hardness salts, scale will be formed after the boiler is heated, thereby reducing the heating efficiency of the boiler, increasing fuel consumption, and even causing damage and explosion due to local overheating of the metal wall. Therefore, water softening treatment must be carried out for low-pressure boilers;Water softening and desalination treatment must be carried out for medium and high pressure boilers.

Characteristics of softened water equipment

1High degree of automation

After installation and commissioning, the specialized boiler softening water equipment for the power industry only needs to regularly add regenerated salt, and the boiler softening water equipment will automatically and continuously produce water, saving manpower and material resources.

2Low energy consumption and low operating costs

Special boilers for the power industryWater softening equipmentThe overall design is reasonable, the exchange capacity of the resin is fully utilized, and the energy consumption indicators of the boiler softening water equipment are significantly lower than those of general softening water equipment.

3The structure design of the specialized boiler softening water equipment for the power industry is reasonable, easy to operate and maintain, occupies a small area, and saves investment.

4Long service life with minimal maintenance in the later stages

The design of each pressure bearing part of the core components inside the control valve must meet the requirements0～13kgf/cm2And cyclic pressure experiment250000Secondly, the core components such as the plunger valve core and plunger rod must be made of lead-free brass material, which is sturdy and durable, with a service life of up to27Year.

5Widely applicable

The specialized boiler softening water equipment for the power industry is suitable for the water softening treatment of industrial and civilian boilers, heat exchangers, air conditioners and refrigerators, and chilled water circulation systems. It is widely used in softening treatment systems for water in power plants, steel mills, textiles, pharmaceuticals, chemicals, food and beverage industries, etc.

6Excellent anti-corrosion performance

Mainly using fiberglass or stainless steel resin tanks,PEPlastic or fiberglass salt tanks have the characteristics of corrosion resistance, no pollution to water quality, and also avoid resin pollution.

Working procedure of softened water equipment

1Water supply: Raw water undergoes an exchange reaction through a resin layer to produce soft water.

2Backwash: Water enters from the lower layer of resin, loosens the resin, and removes fine impurities.

3Regeneration of salt water: Using a higher concentration of salt water to flow through the resin, the failed resin is restored to a sodium type usable resin.

4Rinse: According to the process of water supply, rinse excess salt solution and regenerated calcium and magnesium ions through resin.

5Water injection: Inject water into the salt tank to dissolve the salt, which will be used for the next regeneration.
