May I ask about the boiler softening system, who can say probably?

The more primitive ones are: lime-soda ash softening method, which is not used much.

The most commonly used one is the ionic resin exchange bed, which has a smaller investment and more stable water quality.

Reverse osmosis: the water quality is very good, the operation and maintenance are simple, the maintenance cost is very low, the investment is large, there are prospects, and the trend of future development.

At present, industrial boilers generally use sodium ion exchange system, in layman's terms, the softener is a device that can reproduce water, it mainly uses the reversible exchange reaction principle of the exchanger to soften the water quality. The softener goes through the process of making water, backwashing, regeneration, and washing. When the water hardness of the product of the softener exceeds the specified value, it is called invalid and needs to be withdrawn from operation for regeneration.

The prepared regeneration solution (clean industrial salt or table salt solution) is sent to the exchanger, and the calcium and magnesium ions absorbed by the exchanger are replaced in the process of the regeneration liquid flowing through the exchanger bed, and the exchanger is converted to sodium type for the softening of water, but after the regeneration solution is in, the excess regeneration solution and calcium and magnesium ions must be rinsed out. After the water quality of the re-washing is qualified by the analysis and laboratory test, the softener can be transferred to operation. If you choose to equip a softener, it is best to choose a countercurrent regeneration softener, because the countercurrent is more regenerative than the downstream regeneration equipment, relatively speaking, the water quality is good, and the equipment runs stably.

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.

Kiss! Hello, happy to answer your <>

Principle of hydrophilic boiler softened water equipment: because the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+ and Mg2+ (the main ingredient in the formation of scale) 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, 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 the resin out of the tank with the regenerated waste liquid, and the resin will resume the softening and exchange function, I hope mine can help you <>

Do you have any other questions?

Hello dear, according to the situation you described, the working principle of boiler water softening equipment: since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resins (softeners) are generally used to replace Ca2+ and Mg2+ (the main components of scale formation) in water. With the increase of Ca2+ and Mg2+ in the resin, the efficiency of resin to remove Ca2+ and Mg2+ gradually decreased.

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 brine in the salt box and replace the hardness ions on the resin. After the recycled waste liquid is discharged from the tank, the resin resumes its softening and exchange function.

Since the hardness of water is mainly formed by calcium and magnesium, and the hardness of water is mainly formed by calcium and magnesium, and the principle of sodium ion exchange softening is through sodium ion exchange resin through raw water. The hardness components Ca2+ and Mg2+ in the water are exchanged with the Na+ in the resin, so that the Ca2+ and Mg2+ in the water are adsorbed and the water is softened.
