How to calculate the cost of boiler softened water, the cost of boiler softened water

The working principle of intelligent 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.

With the continuous progress of the exchange process, all the Na+ in the resin is placed out and then loses the exchange function, at this time, the resin must be regenerated with NaCl solution, the resin adsorbed Ca2+, Mg2+ is replaced, the resin readsorbs sodium ions, and the softening exchange capacity is restored. 1. Backwashing: After working 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 removing these dirt, the ion exchange resin can be completely exposed, and the regeneration effect can be guaranteed.

The backwash process is in which water flows in from the bottom of the resin and out from the top, so that the dirt trapped at the top can be washed away. This process generally takes about 5-15 minutes. 2. Salt absorption:

In the process of injecting brine into the resin tank, the traditional equipment uses a salt pump to inject the brine, and the fully automatic equipment uses a special built-in ejector to suck the brine in. In the actual working process, the regeneration effect of brine flowing through resin at a slower speed is better than the effect of simply soaking resin in brine, so the softened water equipment is regenerated by the method of slow flow of brine through resin, which generally takes about 30 minutes, and the actual time is affected by the amount of salt used. 3. Slow rinsing:

After flowing through the resin with salt water, the process of slowly rinsing all the salt in the resin with the same flow rate with raw water is called slow flushing, because there are still a large number of calcium and magnesium ions on the functional groups in this washing process are exchanged by sodium ions, according to practical experience, this process is the main process of regeneration, so many people call this process replacement. This process is generally the same as the time for salt inhalation, i.e. about 30 minutes. 4. Quick rinse:

In order to thoroughly rinse the residual salt, the resin should be rinsed with raw water at a flow rate close to the actual operation, and the effluent after this process should be soft water. In general, the quick rinse process takes 5-15 minutes.

Advantages of water softening equipment for power plant boilers.

1. The multi-way valve adopts imported multi-way valve and related control system. The products are stable and reliable, cost-effective, and have been widely used in boilers, air conditioners and other industries for many users in the domestic market.

2. High degree of automation.

After the initial installation and commissioning of the automatic water softening equipment, it only needs to manually add recycled salt regularly, and can achieve continuous water production under fully automatic conditions, saving a lot of manpower and material resources. Most of the equipment adopts a flow control system, and the digital display interface will allow users to understand the equipment situation at a glance.

3. Low power consumption.

Commonly used manual equipment requires at least one salt pump, which often has corrosion problems, and the maintenance workload is also very large, which directly affects the safe and stable operation of the equipment. The fully automatic equipment does not need a salt pump, and the power consumption is < 20W.

4. Anti-corrosion and anti-pollution.

The bed body of the automatic water softening equipment is made of anti-corrosion materials such as FRP, and the pipeline is made of ABS engineering plastics, which has strong corrosion resistance, so as to completely solve the problem of equipment corrosion.

5. The structure is reasonable and the installation is convenient.

Traditional manual equipment occupies a large area and the equipment is heavier, and the installation requires a special civil foundation. The overall design of the automatic equipment is reasonable, the floor area is greatly reduced compared with the traditional equipment, and the light structure makes the equipment easy to install, and can be flexibly arranged according to the site conditions.

Look at the water softening equipment, the cost of different equipment is different, but basically it is not cheap, and if the area is very large, you can't afford it.

Look at the production process and the indicators of raw water. If it is a traditional resin process, the main consumption is raw water** (loss +1) + tons of water salt consumption salt** tons of water labor wages tons of water depreciation tons of water resin consumption.

The reverse osmosis process avoids the consumption of salt and resin, but the power consumption increases, which is calculated according to the above data according to the specific situation.

The production cost of boiler soft copy converter equipment is more complex than the effect, one is the material (glass fiber reinforced plastic, stainless steel, carbon steel), production staff salary, electricity costs, purchased parts and other costs, of course, there is the problem of softener specifications, the greater the output of the softener, the higher the value, the key is to choose to adapt to the high hardness of raw water quality softening, floating bed process control valve to cooperate with the softening resin tank control system, we are the enterprise that should have the technical strength of this floating bed multi-way valve, it depends on whether you can have this vision. Yijie water quality.

The method of boiler softened water hardness is as follows: you can choose to use a water hardness tester to test the degree of water hardness, which can be confirmed by comparing the hardness table of the tester.

Control index of boiler water: the content of insoluble solid mixture separated by suspended solids after filtration. (If the suspended solids directly enter the pot, the organic matter in the furnace water will increase, resulting in the co-production of steam and water.)

It usually refers to the total content of calcium and magnesium ions, which is an important indicator to prevent boiler fouling. For the boiler, the less hardness in the water, the better, and controlling the hardness of the feed water can control the rate of boiler fouling.

The total amount of carbonate, bicarbonate, hydroxide and other acid substances contained in each liter of water. That is, the negative logarithm of the concentration of hydrogen ions, which is an indicator of the acidity and alkalinity of dissolution. Too low or too high a pH value is not conducive to the anti-scaling and anti-corrosion of the boiler.

It can be measured with pH test paper, pH value is 7, water is acidic; pH = 7, water is neutral; With a pH of 7, the water is alkaline.

At present, there is a new type of water hardness testing agent, the specification is, the test operation is simple, sampling at any time, instant testing, no need to calculate (only a few drops are needed during titration, for example: 100ml water sample consumes every drop of test solution, two drops, and so on....), the test results are consistent with the results of traditional methods.

There are many ways to express the hardness of water quality, among which there are many expressions of mg L and mmol L.

1. Hardness comparison:

There is no unified representation method at home and abroad. German hardness (DH) is expressed, that is, 10mg (10mg L) of calcium oxide per liter of water is 1 degree (DH), and drinking water should not be greater than 25 degrees.

In addition to the above methods, there are also calcium oxide (mg L), calcium carbonate (mg L) and millimole (mmol L) expressions. The following table lists the methods used to convert Dura Hardness (DH) to other expressions:

Expression: Hardness, Calcium Oxide, Calcium Carbonate, Millimol.

Corresponding value 1 10

2. Summary of knowledge:

1. The total hardness of water = the total content of calcium and magnesium in water. The unit of hardness of water is usually the conversion of all salts in the water to calcium carbonate.

2. When the hardness in the water is less than 150 milligrams of calcium carbonate, it is called soft water; 150-450 mg liters, called hard water; 450-714 mg liters, known as high hard water; More than 714 mg liters of extra hard water.

3. The sanitary standard for the hardness of drinking water in GB5749-2006 is less than 450mg L (calculated as calcium carbonate).

3. Test Method:

1. Rinse the colorimetric tube twice with a water sample, then take a water sample to the scale, add hardness reagent A10 dropwise and shake well, add hardness reagent B and shake it a little (the water sample is red), and then add hardness reagent C dropwise, shake while adding, drop until the water color turns from red to blue, and write down the number of drops of reagent C.

2. Calculation method: total hardness = number of drops of reagent C.

4. Other expressions:

1. The daily water has several hardnesses, which means MMOL L, such as 8 hardnesses refers to 8MMOL L;

2. There is a 50-digit relationship between Mg L and MMOL L, for example, the hardness of water is 100mg L, which is converted to 2mmol L; If calculated as calcium carbonate caCO3) =.

3. Example: 100mg L=2mmol L; 50mg/l=1mmol/l;30mg/l=。

4. Other expressions: The hardness of water refers to the concentration of calcium and magnesium ions in water, and the unit of hardness is ppm, and 1ppm represents the calcium carbonate content in water 1mg.

Consume 3ml of ammonia buffer, consume, (EDTA concentration, take 100ml of furnace water. Calculation:

"Shijiazhuang Lusheng Water Treatment" is good, the company is wholesale, cheap, good after-sales.

Boiler demineralized water is used to remove calcium, magnesium and other ions in the water, can convert hard water into softened water, its water quality is definitely better than tap water, hand washing is no problem, but it cannot be the same as using soap.

The water used in the boiler must be softened, otherwise the scale in the furnace will be **.

Demineralized water is also a precursor to the production of purified water.

Now some color is added to the hot water for heating, and judging by your problem, it is your own boiler, and this water is alkaline water and is not toxic.
