Is it better to use pure water or soft water for the boiler

Long-term use of the boiler will produce a large amount of scale, which will have a serious impact on the safe operation of the boiler. Because the deposition of scale has an obvious impact on people's life and production, production water and domestic water have certain requirements for hardness index, especially if the boiler water contains hardness salts, it will generate scale on the heating surface of the boiler, thereby reducing the thermal efficiency of the boiler, increasing fuel consumption, and even damage the parts due to local overheating of the metal wall. Therefore, for low-pressure boilers, water softening treatment should be carried out; For medium and high pressure boilers, water softening and desalination should be carried out.

Introduction to boiler softened water equipment process:

1.Water supply: Untreated water passes through the resin layer, and an exchange reaction takes place to produce soft water.

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

3.Influent brine regeneration: A higher concentration of brine is used to flow through the resin to re-reduce the failed resin to a sodium-based usable resin.

4.Flushing: According to the process of water supply, the water is washed out of excess salt and regenerated calcium and magnesium ions through resin.

5.Water filling: Fill the salt tank with water to dissolve the table salt for the next regeneration.

Nowadays, steam boilers are commonly used in the boiler industry, and it is recommended to use pure water equipment for steam boiler water purification.

It must be pure water, but the cost is relatively high!

Generally, there are more softened water than pure water, and if the economic conditions are better and you are afraid of trouble, it is better to use pure water.

Relatively; The softened water equipment (sodium ion system) can only treat the hardness in the raw water, (the alkalinity of the raw water does not change). However, pure water equipment (desalination system) can not only remove hardness and other (cations), but also effectively remove alkali (anions).

At present, in addition to the use of brine (pure water) systems for "subcritical or critical power generation boilers", China still focuses on softening applications.

Soft water. Both soft water and pure water have removed hardness ions, which can theoretically be used in boilers, but the cost of soft water is lower than that of pure water, so soft water is used in boilers.

Of course, pure water is better, pure water quality is higher than soft water, pure water is produced by pure water equipment, soft water is produced by softened water equipment, soft water equipment filtration is mainly to reduce the hardness to meet the standard, pure water equipment filtration is to purify all kinds of impurities and microorganisms in the water.

The selection of pure water equipment to purify the make-up water of the power boiler can not only effectively prevent and reduce the accidents caused by boiler scaling, corrosion and deterioration of steam quality, but also help promote the smooth and reliable operation of the unit.

The working principle of intelligent fully automatic water softening equipment.

The hardness of water is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. When the raw water containing hardness ions passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are replaced with the sodium ions in the resin, and the resin adsorbs the calcium and magnesium ions and the sodium ions enter the water, so that the water flowing out of the exchanger is the softened water with the hardness ions removed.

As the exchange process progresses, the resin is full of Na+.

At this time, the resin must be regenerated with NaCl solution to replace the Ca2+ and Mg2+ adsorbed by the resin, and the resin re-adsorbs sodium ions and restores the softening exchange capacity.

Preparation process of desalination water equipment for large-scale power plants.

1. The ion exchange method is adopted, and the process is as follows:

Raw water, raw water pressurized pump, multi-media filter, activated carbon filter, water softener, precision filter, cation resin filter bed, anion resin filter bed, anion and cation resin mixed bed, microporous filter, water point.

2. Reverse osmosis + mixed bed mode is adopted, and the process is as follows:

Water Pipe Network Raw Water Pump Flocculation Dosing Mechanical Filter Activated Carbon Filter Scale Inhibitor Dosing Security Filter High Pressure Pump Reverse Osmosis Device Intermediate Water Tank Mixed Bed Pump Mixed Bed Device Precision Filter Desalination Water Tank.

3. The EDI method is adopted, and the process is as follows:

Raw Water Raw Water Pressurized Pump Multi-media Filter Activated Carbon Filter Water Softener Precision Filter First-stage Reverse Osmosis Machine Intermediate Water Tank Intermediate Water Pump EDI System Microporous Filter Water Point.

Comparison of production processes.

At present, the process of preparing ultrapure water for complete sets of boiler supply desalination station equipment is basically the above three, and the rest of the process flow is mostly derived from different combinations and collocations on the basis of the above three basic processes. Their advantages and disadvantages are listed below:

The first use of ion exchange resin has the advantage of less initial investment and less space, but the disadvantage is that it needs to be regenerated frequently, consumes a lot of acid and alkali, and has a certain damage to the environment.

The second uses reverse osmosis + mixed bed, which is the most economical process for producing ultrapure water, which needs to be regenerated with acid and alkali to continuously produce ultrapure water, which is destructive to the environment. The advantage is that the initial investment is relatively cost-effective. This is also an acceptable process for many thermal power companies.

The third uses reverse osmosis as pretreatment and then electrodeionization (EDI) device, which is the current economical and environmentally friendly ultrapure water preparation process for ultrapure water, which can continuously produce ultrapure water without regeneration with acid and alkali, and is not destructive to the environment. The disadvantage is that the initial investment is too expensive compared to the above two methods.

It is only when the body reaches a certain amount that the body will have symptoms.

Calcium: Calcium. The concentration of magnesium ions is the main indicator of the success of water.

The water quality is too high, which can cause dysfunction. The incidence of stones is high. However, calcium deficiency in the human body can cause rickets.

Osteomalacia and osteoporosis. 99% of the calcium in the body is found in bones and teeth. Magnesium:

Magnesium deficiency can cause myocardial lesions, weak bone and tooth growth, etc. 70% of the magnesium in the human body is found in bones, and the rest is found in various soft tissues and body fluids.

Summary. The so-called soft water refers to water that contains or contains less soluble calcium and magnesium compounds (soft water).

Soft water is less prone to scum than soap, while hard water is the opposite. Natural soft water generally refers to river water, river water, and lake (freshwater lake) water.

What is the difference between soft water and pure water for boiler feed water? Why?

The so-called soft water refers to the water pin (soft water) that contains or contains less soluble calcium and magnesium compounds. Soft water is less prone to scum than soap, while hard water is the opposite. Natural soft water generally refers to river water, river water, and lake (freshwater lake construction) water.

Please refer to the above teachers, I hope to help you, I wish you a happy life!

The use of soft water can extend the life of its boiler. Senlu's unsoftened water is prone to scale, which leads to low boiler power, and can also damage the internal components of the boiler, resulting in boiler damage.

Soft water refers to water that does not contain or contains less soluble calcium and magnesium compounds. Soft water is less prone to scum than soap, while hard water is the opposite. Natural soft water generally refers to river water, river water, and lake water.

Softened hard water refers to the demineralized water obtained when the calcium and magnesium salts are reduced to 50 mg per liter. Although boiling can be used to turn temporary hard water into soft water, it is extremely unprepared to treat large amounts of water in industry.

Demineralized water is a water treatment method that is produced by removing hard positive ions such as calcium and magnesium from the water. However, demineralized water is not suitable for direct drinking, as the ion exchange resin used in the softening process releases sodium ions into the water, increasing the sodium content in the water. <>

High sodium water may have some effects on physical health, especially for those who need to limit their sodium intake, such as those with high blood pressure or kidney problems.

Excessive sodium intake can increase blood pressure and negatively affect heart health.

Therefore, demineralized water is generally not recommended for direct use as a source of water for the sake of drinking. In household use, softened water is often used for rinsing and cleaning activities such as laundry, dishwashing, bathtub and sink cleaning, etc. For the demand for drinking water, it is advisable to choose other types of water sources, such as raw tap water or properly filtered water.

The water softener treatment process increases the sodium content of the water. Moderate sodium intake is acceptable for normal healthy people, but for those who need to limit sodium intake, such as those with high blood pressure or kidney disease, demineralized water may not be suitable as drinking water. <>

A high-sodium diet has been linked to health problems such as high blood pressure, cardiovascular disease, and kidney problems. If you have concerns about these health issues, it is recommended to choose a low-sodium water source.

Demineralized water removes hardness ions, including calcium and magnesium, which are beneficial to the human body. If you rely on drinking water for these minerals, demineralized water may not be enough to meet your state's needs. You can get the calcium and magnesium you need through other foods or supplements.

In general, demineralized water is not designed for direct consumption. Further treatment of the demineralized water is carried out, e.g. with the help of a reverse osmosis system to remove sodium chain ions. <>

Boiler demineralized water is water that has been softened and is commonly used in industrial and commercial fields for boiler water supply, cooling systems, and other process water. While softened water can remove some of the hardness components from the water, it may contain some other chemicals such as salts and other treatment agents. Generally speaking, boiler softened water is not suitable for direct drinking.

This is because boiler demineralized water may contain higher salinity, which may have some impact on human health. In addition, salts and other treatment agents used in the softening process may also have an impact on water quality. If you need drinking water, it is recommended that you choose specially treated and filtered drinking water, such as bottled water, filter-filtered tap water, or other certified drinking water sources.

This allows for better assurance of water quality safety and compliance with drinking water standards. It's best to follow local water standards and recommendations to ensure the health and safety of you and your family. If necessary, you can consult your local water authority or professional body for more accurate and specific advice.

Generally speaking, boiler demineralized water is not recommended to drink demineralized water because it contains a large amount of calcium and lime, which is relatively astringent and will affect people's health. However, if the water quality meets the national quality standards after treatment, then the boiler softened water can also be drunk, but the taste is poor, and calcium ions will affect the alkalinity of the water, which is not conducive to the quality of drinking water. In addition to Eggplant-Softening Changzaicha, there is also a reverse osmosis (RO) technology that can remove most of the harmful substances such as heavy metals, minerals and contaminants from the water, but this requires the selection of the right reverse osmosis membrane to work best.

In general, it is better for people not to drink demineralized water directly, we can choose water that has been treated with reverse osmosis or water that has been treated by water treatment equipment in order to get water that is more in line with people's drinking standards.

Hard water refers to water that contains more calcium and magnesium ions, and soft water refers to water that contains less calcium and magnesium ions The way to distinguish between hard water and soft water is: use soapy water or heating method, if the hardness of the water is relatively large, it will produce a large amount of scale If the scale is collected too much, it will cause the boiler **, which is more dangerous Therefore, the answer is: if the hardness of the water is relatively large, a large amount of scale will be produced The scale is collected too much, which will cause the boiler **, which is more dangerous, so the boiler can not use hard water
