On reverse osmosis, collect the return water.

The boiler softening limb of the softened water equipment is the use of resin to distribute the softening technology of Peishili through the sodium ion exchange softening method of water, that is, when the raw water passes through the sodium ion exchanger, the Ca2+ and Mg2+ in the water are replaced by the Na+ in the exchanger, so that the calcium and magnesium compounds that are easy to scale are transformed into soluble sodium compounds that do not form scale and the water is softened.

Boiler softening using water softening equipment has the following benefits:

1. When using boiler softened water equipment, a lot of waste of fuel is greatly saved. When a thick layer of scale slowly forms after boiling water in a boiler, a 1 mm scale will form for a boiler with a working pressure, and 8% of fuel will be wasted. It's not just a waste of fuel, it's also polluting the environment.

2. Boiler softened water equipment has the effect of improving thermal efficiency and reducing output. When scale occurs on the evaporation surface of the boiler, the output of the boiler will be reduced because the heat from the fire side cannot be transferred to the water side quickly. If the water is treated improperly, when the boiler is scaled, the boiler steam capacity will be greatly reduced, and it will not be able to operate automatically due to insufficient gas supply.

3. The use of softened water equipment will reduce boiler overhaul. When the boiler pipe produces a large amount of scale, it is very difficult to remove, and then because the scale will cause a series of hazards such as leakage, deformation, corrosion and so on of the boiler. It not only damages not only the boiler, but also consumes a lot of manpower and material resources to overhaul, which not only shortens the running time, but also increases the maintenance cost.

4. The application of softened water equipment reduces the danger to safety, and the accidents caused by scale in the boiler account for more than 20% of the total number of boiler accidents, which not only causes equipment loss, but also threatens personal safety. The cost of sailing and operating water treatment accounts for a quarter of the savings. For example, the selection of softened water equipment must be based on the principle of quality and safety to ensure that it can play an effective role in the softening of water quality.

According to the specific problem type, the steps are disassembled, the cause is analyzed, the content is expanded, etc.

The specific steps are as follows: What are the main reasons for this?

Water is the main working medium of the boiler and is known as the blood of the boiler. Poor water quality will cause scaling on the heating surface of the boiler, greatly reduce the heat transfer efficiency, increase coal and electricity consumption, reduce steam quality, and cause overheating, corrosion and damage to the metal on the heating surface of the boiler, and bulging, deformation, pipe bursting, and even accidents. Therefore, the normal operation of water softening equipment is essential to ensure the safe and economical operation of the boiler.

At present, automatic water softening equipment is widely used in boiler feed water softening, but many years of water treatment experience found that many users do not understand the workflow of water softening equipment, resulting in equipment resin replacement and salt can not meet the demand, resulting in the abnormal operation of automatic water softening equipment, and the deterioration of soft water quality is common. In view of this problem, the workflow of the equipment is summarized for your reference.

The workflow of a fully automated water softener is broadly divided into five steps.

1.Regeneration: automatic water softening equipment mostly uses a special built-in ejector to suck in the brine (as long as the water has a certain pressure), in actual operation, the regeneration effect of the brine flowing through the resin at a slower speed is better than the effect of simply soaking the resin in the saline, so the softened water equipment is regenerated by the method of slow flow of brine through the resin, this process generally takes about 45 minutes, and the actual time is affected by the amount of salt.

2.Slow washing: After the automatic water softening equipment works for a period of time, the equipment will intercept a lot of dirt brought by the raw water on the upper part of the resin, and after these dirt are removed, the ion exchange resin can be completely exposed, and the regeneration effect can be guaranteed.

The backwash process is when water is washed in from the bottom of the resin and flows out from the top, so that the dirt trapped at the top can be washed away. This process generally takes about 10-15 minutes.

3.Washing: In order to thoroughly rinse the residual salt, the resin should be rinsed with raw water at a flow rate close to the actual work, and the final water of this process should be soft water. In general, the fast rinse process is 10-15 minutes.

4.Salt tank water injection: provide sufficient water for the next regeneration process, fully dissolve the regenerant, so that the resin can be fully regenerated and reduced. This process generally takes 5-8 minutes, and the filling time is adjusted according to the raw water pressure.

5.Softening: The raw water enters the bottom of the resin tank through the control valve, and the water flows upwards to lift the resin layer through the water distributor, and then flows out through the controller, so that the water is softened to obtain soft water.

Demineralized water equipment complex.

Installation requirements. System 1, foundation.

Bai needs to be horizontal, nearby.

DU is provided with floor drains or drainage ditches to drain away the regenerated DAO wastewater. There should be an independent power socket near the automatic water softener equipment.

2. The salt box should be close to the exchange tank, and the shorter the salt suction pipe, the better.

3. A Y-type filter and a water meter should be installed on the inlet pipe, and a sampling port should be set up at the water outlet.

4. A manual valve should be installed on the inlet and outlet pipes, and a bypass valve should be set between the inlet and outlet outlets, so as to continue to supply water during regeneration or maintenance.

5. If the water pressure at the inlet is lower, an automatic booster water pump should be added.

6. The salt in the salt box is required to be industrial salt, and no iodized salt or calcium salt can be added. In order to ensure that the concentration of the salt solution in the salt box can reach saturation, the dissolution time should be not less than 6 hours, and the regeneration should be forced once before the first use.

7. When the hardness of raw water is 6mmol l, 1-2 grades should be increased.

Because the hardness of water is mainly composed of calcium and magnesium, cationic exchange resin is generally used to replace Ca2+ and Mg2+ (the main component of scale formation) in the water, and with the increase of Ca2+ and Mg2+ in the resin, the efficiency of resin to remove Ca2+ and Mg2+ gradually decreases. When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated, and the regeneration process is to rinse the resin layer with the salt water in the salt box, replace the hardness ions on the resin, and discharge it out of the tank with the regenerated waste liquid, then the resin will resume the softening and exchange function.

The softened water equipment uses sodium ion exchange resin to replace the calcium and magnesium ions in the raw water, and after the equipment flows out, it becomes demineralized water with very low hardness. When the resin adsorbs a certain amount of calcium and magnesium ions, it must be regenerated. The softened water is soaked in saturated brine to replace the calcium and magnesium ions in the resin, restore the softening and exchange capacity of the resin, and discharge the waste liquid.

In daily life, we often see limescale forming on the inner wall of the kettle after a long period of use. What is the reason for this? It turns out that the water we take contains a lot of inorganic salts, such as calcium, magnesium salts, etc.

These salts cannot be found by the naked eye in water at room temperature, and once they are heated and boiled, a lot of calcium and magnesium salts are precipitated in carbonate formation, and they form scale close to the wall of the pot. We usually use the content of calcium and magnesium ions in water as the index of "hardness". A hardness of 1 degree is equivalent to 10 mg of calcium oxide per liter of water.

Water below 8 degrees is called soft water, above 17 degrees is called hard water, and between 8 and 17 degrees is called moderate hard water. Rain, snow, rivers, rivers, and lakes are all soft water, and spring water, deep well water, and sea water are hard water.

Softened water has the following effects:

1) Prevent water pipes, water heaters, coffee machines, humidifiers, steam irons, bathtubs, shower heads, flush toilets and other household appliances from accumulating scale, frequent blockage, and low thermal efficiency.

2) Brewing coffee and tea leaves, the taste is unique and pure. Raise flowers, prolong the flowering period, green leaves without spots, and gorgeous flowers. Fish farming to prevent all kinds of fish diseases. Soft boiled rice is full, fluffy, and has a good taste; Sanitary utensils, crystal clear, no stains.

3) Extend the shelf life of tofu, soybean milk is more fragrant, bean sprouts do not need auxin, and grow strongly. Wash vegetables, remove pesticide ingredients, and prolong the shelf life of vegetables. Cooking rice shortens the time, the rice grains are soft and smooth, and the pasta is not easy to swell. Cooking, preserving the natural taste and nutrients of vegetables.

4) Effectively inhibit fungi, promote trauma healing, and reduce the incidence of constipation, gastrointestinal and stone diseases. In the event of an accident such as skin trauma, frostbite, burns, etc., wash the affected area with soft water, soak cotton wool, gauze, towel, etc., and gently rub the affected area, which can quickly heal the wound and make the swelling caused by the burn disappear immediately, because the soft water has the effect of promoting the regeneration of cells and tissues. It can effectively inhibit fungi and promote the regeneration of cell tissues.

In the event of an accident such as skin trauma, frostbite, or burns, the wound can be quickly healed by washing it with soft water.

5) Laundry, prevent static electricity, decolorization, deformation, clean tableware, clean without water stains, and improve the gloss of utensils. Clean the kitchen and bathroom, and remove stains and odors strongly. It has strong detergency. Soft water washes the clothing fibers, which will not be hard and brittle, saving washing supplies.

6) Soft water fundamentally eliminates water alkali, makes the equipment operate safely, saves expenditures, reduces the maintenance cost of water equipment and water pipelines by more than 60%, reduces the cost of hot water fuel by more than 30%, and reduces the purchase cost of detergent by more than 50%.

Waterproof! There is a lot of scale, and the boiler has the most risk!

Boiler softened water equipment is one of the commonly used systems in the field of industrial production, but when the boiler water contains hard salts, such as calcium and magnesium ions, etc., it will generate scale on the heating surface of the boiler, thereby reducing the thermal efficiency of the boiler, increasing fuel consumption, and may even cause local overheating and damage to components. Therefore, industrial boilers should be softened or desalination. (In industry, it is generally believed that water with a hardness of <1 is called soft water, between 1 and 10 is generally called hard water, and water with a hardness of 10 is mostly called high hard water).

The carbon steel tank is the essence of the composite series products. The wrought iron is welded on the surface of the steel body by a special process, and the product has the characteristics of no joints, no leakage, no toxicity, anti-aging, impact resistance, corrosion resistance, long life, and composite health standards. Longer service life under natural conditions.

Therefore, it is an extremely excellent corrosion-resistant product. Compared with the traditional steel-lined plastic plate storage tank, steel-lined rubber storage tank, FRP tank body and steel-lined FRP storage tank, it has better corrosion resistance, no leakage, no peeling, wear resistance, can withstand a certain pressure, can withstand higher temperature, and has a long life, which is a necessary storage tank for softened water resin.
