The softened water treatment device is also called a fully automatic water softener, a softened water treatment device, and a water softener. The water softener equipment is composed of a fully automatic soft water controller resin tank (generally a FRP resin tank and a stainless steel resin tank), a strong acid type sodium ion cation resin, and a salt tank.

Equipment structure

1. Control valve: The valve body is made of high-strength lightweight corrosion-resistant engineering plastic and lead-free brass.

2. Corrosion-resistant tank body: The material of the tank body is FRP (optional carbon steel or stainless steel lining plastic tank body), the tank body is anti-corrosion, pressure-resistant and has a long service life.

3. Uniform water distribution system: the use of jet-type cloth water, the effective exchange capacity of the resin can be fully exerted, with salt control accuracy, no salt pump.

4. Imported high-performance resin: the choice of strong acid cation exchange resin, low damage rate, uniform particle size, improve ion exchange rate.

Working principle

The softened water equipment uses the principle of ion exchange to remove scale ions such as calcium and magnesium in the water. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are replaced with the sodium ions adsorbed by the resin, and the resin adsorbs calcium and magnesium ions and the sodium ions enter the water, so that the water flows out of the exchanger. Water is the softened water from which the hardness is removed.

Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (softener) is generally used to displace Ca2+ and Mg2+ (the main component forming scale) in the water. With the increase of Ca2+ and Mg2+ in the resin, The efficiency of resin removal of Ca2+ and Mg2+ is gradually reduced.

When 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 the brine in the salt tank, and the hardness ions on the resin are replaced, and the resin is discharged with the recycled waste liquid. The softening exchange function is restored.

Selection

1. First, you need to provide the system you need to use demineralized water:

1) Heating 2) Cooling water supply 3) Process water 4) Steam boiler 5) Iron and steel smelting industry 6) Chemical pharmaceutical industry

2. System water time:

That is, running time / hour water consumption / average / peak /

Does the equipment need continuous water supply? If necessary, choose a twin-control or dual-control twin series, otherwise you can choose a single-valve single-tank series.

3. The total hardness of the source water

The water source is the municipal tap watergroundwatersurface water source, and the total hardness of the raw water in the area of use. For a certain type of water softener, the hardness of the raw water is high, and the cycle water production amount must be relatively reduced, thereby causing frequent regeneration of the soft water equipment. Relatively reduce the service life of the resin. In order to avoid such a situation, the resin volume should be increased, which means that an increased model water softener is used.

4. Required soft water unit flow (ton/hour).

This is determined by the nature and requirements of the user equipment.

5. The setting of the cycle water quantity

After the water softener model is set, the theoretical working cycle water production (ton) can be determined based on the raw water hardness and the exchange working capacity of the resin used.

Application

It can be widely used in the softening of make-up water in steam boilers, hot water boilers, exchangers, evaporative condensers, air conditioners, direct combustion engines and other systems. It can also be used in the treatment of domestic water such as hotels, restaurants, office buildings, apartments, homes, and softened water treatment in food, beverage, brewing, laundry, printing and dyeing, chemical, pharmaceutical and other industries.
