Fully automatic power plant boiler water treatment equipment

I. Introduction to Fully Automatic Power Plant Boiler Water Treatment Equipment Fully automatic power plant boiler water treatment equipment is a relatively advanced device, which is a pure physical process preparation technology. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water are exchanged with the sodium ions adsorbed by the resin. The resin adsorbs the calcium and magnesium ions while the sodium ions enter the water. Thus, the water flowing out of the exchanger is softened water with the hardness removed. Since the hardness of water is mainly formed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+ and Mg2+ (the main components of scale) in water. As the amount of Ca2+ and Mg2+ in the resin increases, the efficiency of the resin in removing Ca2+ and Mg2+ gradually decreases. When the resin absorbs a certain amount

Faults Encountered in the Use of Water softening Equipment (Beijing Yuanlai)

Water softening equipment is also known as water softening devices, water softeners, water softeners, water softening equipment, and water quality softeners. He uses cation resin to soften the source water. The main purpose is to have the cation resin adsorb calcium and magnesium ions (the main components of scale) in the water, reduce the hardness of the source water, and it can also be intelligently regenerated and recycled. Its main uses: softening and desalination, electronic descaling devices, filtration and separation, boiler softening, industrial softening equipment, softening devices, household tap water softening, etc. When reverse osmosis equipment is used to treat groundwater to produce pure water, a water softening device is also configured to fully remove calcium and magnesium ions from the water. The composition of a resin softening device: A resin softening device uses the principle of ion exchange to remove scale-forming ions such as calcium and magnesium from water. It is usually composed of a controller, a resin tank, and a salt tank

The reasons for the increase in the conductivity of purified water

1. Scaling pollution: excessively high recovery rate, deteriorating water quality, poor quality of scale inhibitor, unreliable addition of scale inhibitor, etc. 2. Leakage of connecting parts: O-ring leakage, leakage of connecting parts. 3. Temperature rise: salt permeability increases as temperature rises. 4. Increase in influent conductivity: The increase in influent conductivity directly leads to an increase in the conductivity of the produced water, errors in conductivity meters, etc. 5. Increase in recovery rate 6. Reduced operating pressure: Lower operating pressure can cause an increase in conductivity, such as temperature rise, which does not require a higher operating pressure. 7. Reduced membrane element performance: Membrane element scratches, membrane oxidation, chemical cleaning damage, etc. 8. Organic contamination: Pollution, colloid pollution, insoluble NOM pollution, organic matter pollution, etc. 9. Abnormal PH value: The PH value is too high

Common faults of water softening equipment

The reason why the water softening equipment does not produce soft water: The bypass valve is not opened. Solution: Open the bypass valve. Resin leakage. Solution: Check whether the resin tank is damaged to ensure its integrity. Solution for insufficient salt in the salt tank: Check if there is enough salt in the salt tank and add salt to the severe case. Solution to resin failure: Resin failure may be caused by regeneration failure. Regenerate the resin again. Cause of low water pressure: Clogged inlet pipe. Solution: Clean and unclog the inlet pipe or replace it. Solution for a broken water pipe: Inspect the water pipe and replace the broken one. Solution to water valve leakage: Check the water valve to ensure it is functioning properly to prevent leakage from affecting water pressure. The water softening equipment is not in operation

The difference between softened water and other types of water

In daily life, we often see that scale forms on the inner walls of kettles after long-term use. What's the reason for this? It turns out that the water we took contains a considerable amount of inorganic salt substances, such as calcium and magnesium salts. These salts cannot be detected by the naked eye in water at normal temperature. Once they are heated and boiled, a considerable amount of calcium and magnesium salts will precipitate in the form of carbonates. When they adhere to the inner walls of the kettle, they form scale. We usually refer to the content of calcium and magnesium ions in water as "". "Hardness" This indicator is used to represent it. A hardness of 1 degree is equivalent to 10 milligrams of calcium oxide per liter of water. Water with a temperature below 8 degrees is called soft water, water with a temperature above 17 degrees is called hard water, and water with a temperature between 8 and 17 degrees is called moderately hard water. Rain, snow water, river water, lake water are all soft water, while spring water, deep well water and sea water are all hard water. Let's take a look at the soft part again

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
