Detailed explanation of the operation process of the automatic controller of the softened water equipment

the softened water equipment randomly collects the output water volume information through the sensor flowmeter on the outlet pipe and inputs it into the computer in time. After storage and calculation, it sends instructions to the multi-way servo valve or solenoid valve to stop the corresponding operation. At the same time, the relevant information is synchronously reflected back to the microcomputer When the system needs regeneration, the computer controls the solenoid valve to cut off the outlet pipe channel, and the preset program is started at a fixed time, so that the backwashing salt absorption washing water injection and other processes can be stopped accurately. Microcomputer can optimize the preset according to the needs of users

the periodic set water output, residual water volume, water flow per unit hour, periodic salt consumption, time of each regeneration and current working form of the softened water equipment. To meet different needs in operation, the operation of the automatic water softener can be switched to manual regeneration at any time, so as to meet the different requirements of the operating conditions of the water softener

1. Definition of boiler softened water equipment:

boiler softened water equipment is a raw water pretreatment device launched for boiler fouling, which removes calcium and magnesium ions in raw water and the factors that cause boiler fouling

2. Working principle of boiler water softening equipment:

since 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 in water (the main component forming scale). With the increase of Ca2 and Mg2 in resin, the efficiency of removing Ca2 and Mg2 by resin gradually decreases

after the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank, replace the hardness ions on the resin, and discharge the regenerated waste liquid out of the tank, so that the resin can resume the softening and exchange function

since the hardness of water is mainly formed by calcium and magnesium and indicates that the hardness of water is mainly formed by calcium and magnesium and indicates that the principle of sodium ion exchange softening treatment is to exchange the hardness components Ca2 and Mg2 in water with Na in the resin through sodium cation exchange resin, so as to adsorb Ca2 and Mg2 in water and soften water

the impurities that may be contained in the raw water of boiler feed water include: suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and dissolved gases. If this kind of water (mainly calcium and magnesium ions) is not treated, once it enters the boiler, it will bring harm. When suspended solids, colloids and inorganic salts are heated or exceed their saturated concentration, they will settle and precipitate, forming sludge and scale, which will greatly affect the heat transfer efficiency of the boiler and the boiler water cycle, fuel waste, heating surface damage, boiler output decline, and cleaning volume increase

according to the measurement, the boiler with 1mm thick scale wastes 10% of fuel. When the boiler is running without scale, the pipe wall temperature is 280 ℃. After 1mm thick silicates scale, the pipe wall temperature rises to 680 ℃ due to the increase of thermal resistance. At this time, the strength of the steel plate is reduced from 40 kgf/cm ~ 2 to 10 kgf/cm ~ 2, resulting in the decrease of boiler pressure and the cracking, bulging, and even bursting of the boiler wall. Serious scaling can block furnace tubes and waterways, cause boiler shutdown, boiler explosion and other serious accidents, and freeze cracking of production equipment and heating equipment caused by boiler shutdown also occurs from time to time. During chemical cleaning and descaling, improper or frequent pickling will seriously affect the service life of the boiler and pollute the environment

when the water containing calcium and magnesium ions passes through the sodium ion exchanger, the calcium and magnesium ions in the water are bound to the exchanger, and the sodium ions of the exchanger itself are discharged into the water in equal amounts. In this process, if abnormal conditions are found, the machine must be shut down and cut off immediately, reported to the director of the laboratory and repaired by the manufacturer, and the machine must not be disassembled, that is, the raw water is softened; When sodium resin fails and changes to calcium magnesium type, salt solution is usually used to contact the resin to restore the resin to the original sodium type. This process is regeneration, softening, and regeneration cycle to reach raw water treatment. The existence of calcium and magnesium ions in water is the main reason for the formation of scale when the water temperature changes. At present, the commonly used water softening equipment in China mainly includes manual type, domestic combined type, domestic multi valve type and imported multi-channel valve type. Among them, the imported multi-channel valve water softening equipment is the main product in the market at present. This equipment takes the imported multi-channel valve and controller as the core, and is equipped with domestic resin tank, salt tank, pipeline and other materials to form a fully automatic water softening equipment

because the deposition of scale has a significant impact on people's life and production, both production water and domestic water have certain requirements for hardness indicators, especially if the boiler water contains hardness salts, scale will be generated on the boiler heating surface, thus reducing the boiler thermal efficiency, increasing fuel consumption, and even damaging parts and causing explosion due to local overheating of the metal wall. Therefore, water softening treatment should be carried out for low-pressure boilers; For medium and high pressure boilers, water softening and desalination treatment shall be carried out

ion exchange method:

specific cation exchange resin is used to replace calcium and magnesium ions in water with sodium ions. Due to the high solubility of sodium salt, the formation of scale with the increase of temperature is avoided. This method is the most commonly used standard method at present. The main advantages are: the effect is stable and accurate, and the process is mature. The softened water equipment adopting this method is generally also called "ion exchanger" (because it is mostly sodium ion exchange resin, it is also mostly called "sodium ion exchanger")

ion exchange resin is a polymer with corresponding functional gene groups. In general, conventional sodium ion exchange resins contain a large amount of sodium ions

when the content of calcium and magnesium ions in water is high, the ion exchange resin can release sodium ions, and the functional gene group combines with calcium and magnesium ions, so the content of calcium and magnesium ions in water is reduced, and the hardness of water is reduced. Hard water turns into soft water, which is the working process of softening water equipment

there are many impurities in the water that has not been purified, especially calcium and magnesium ions. If these impurities enter the boiler system with the feed water, they will form scale, which will cause great harm:

(1) lead to uneven heating of the boiler and damage to the metal

(2) reduce thermal efficiency and increase energy consumption

(3) lead to metal corrosion

(4) it is easy to deteriorate the steam quality. Among them, scale is the main source of all hazards. The existence of calcium and magnesium ions in water is the main reason for the formation of scale when the water temperature changes. The existence of scale has great hidden dangers for the efficiency and safety of boilers, heat exchangers and other equipment during operation. Therefore, in the national mandatory standards (industrial boiler water quality standards, etc, The emergence of boiler and aircraft carrier has made China's military status have very strict regulations on the hardness of water supply, so boiler water softening equipment has become a necessary equipment supporting boilers

I. The standard workflow of fully automatic softened water equipment mainly includes five processes:

softened water equipment work (sometimes called water production, the same below), backwashing, salt absorption (regeneration), slow flushing (replacement), and fast flushing. All processes of different softened water equipment are very similar, but there may be some additional processes due to the different actual processes of softened water equipment or the need of control. Softened water equipment any softened water equipment based on sodium ion exchange is developed on the basis of these five processes (among them, the full-automatic softened water equipment will increase the salt water reinjection process)

II. Brand introduction of automatic controller of softened water equipment:

introduction of AUTOTROL multi-channel valve and controller:

randomly collect the output water volume information through the sensor flowmeter on the outlet pipe and input it into the computer in time. After storage and calculation, send instructions to the multi-channel servo valve or the expensive solenoid valve of the former for corresponding operation. At the same time, the relevant information is synchronously fed back to the microcomputer When the system needs regeneration, the computer controls the solenoid valve to cut off the channel of the water outlet pipe, and the preset program is started regularly, so that the processes of backwashing salt absorption washing water injection can be operated accurately. The microcomputer can be optimized and preset according to the needs of users. It can display randomly: periodically set water output, remaining water volume, water flow per hour, periodic salt consumption, time of each regeneration and current working mode. To meet different needs in operation, the operation of the full-automatic water softener can be switched to manual regeneration at any time to meet the different requirements of the operating conditions of the water softener
