The definition of boiler softened water equipment: The fully automatic boiler softened water equipment is a pre-treatment device for raw water launched in response to the formation of scale in boilers. It removes calcium and magnesium ions from the raw water as well as the elements that cause scale formation in boilers. 2. Working principle of Fully automatic boiler water softening equipment Since the hardness of water is mainly formed and represented 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 has absorbed a certain amount of calcium and magnesium ions, it undergoes regeneration. The regeneration process involves flushing the resin layer with brine from the salt tank to displace the hardness ions on the resin and then proceed with the regeneration

　　1Definition of boiler softened water equipment:

　　The fully automatic boiler softened water equipment is a pre-treatment device for raw water launched in response to the formation of scale in boilers. It removes calcium and magnesium ions from the raw water as well as the elements that cause scale formation in boilers.

　　2The working principle of the fully automatic boiler water softening equipment

　　Since the hardness of water is mainly formed and represented by calcium and magnesium, cation exchange resin (water softener) is generally used to remove the hardness of waterCa2+,Mg2+The main components that form scale are displaced and carried out within the resinCa2+,Mg2+The increase, resin removalCa2+,Mg2+Its efficiency gradually decreases.

　　When the resin has absorbed a certain amount of calcium and magnesium ions, it undergoes regeneration. The regeneration process involves flushing the resin layer with brine from the salt tank to displace the hardness ions on the resin and discharge them out of the tank with the regeneration waste liquid. Thus, the resin regains its softening exchange function.

　　The hardness of water is mainly formed and represented by calcium and magnesium. The principle of sodium ion exchange softening treatment is to pass the raw water through sodium-type cation exchange resin to reduce the hardness components in the waterCa2+,Mg2+In the resinNa+Exchange with each other, thereby adsorbing substances in waterCa2+,Mg2+Soften the water.

　　The chemical equation for converting hard water to softened water:

　　Calcium removalCaCO3+2NaCl=CaCl2+Na2CO3

　　Removal of magnesiumMgCO3+2NaCl=MgCl2+Na2CO3

　　3Types of control valves for fully automatic boiler softened water equipment:

　　<1>Semi-automatic (manual) control valve

　　<2>Fully automatic flow control valve

　　<3>Fully automatic time-type control valve

　　4Analysis of the Reasons for Excessive Hardness of softened Water in Fully automatic Boiler Softened Water Equipment

　　Analysis of the Reasons for Excessive Hardness of Softened Water in Fully Automatic Boiler Softened Water Equipment:1The sampling port of the soft water equipment was tested as qualified, but the water hardness in the soft water tank exceeded the standard. The reasons for this phenomenon are as follows:AThe regeneration cycle is set too high or the flowmeter malfunctions cause inaccurate measurement, resulting in the resin not being regenerated in time when it should be regenerated, and thus the excess water is injected into the soft water tank.

　　BThe forward wash time is too short, causing some of the waste brine that should have been washed away during the forward wash to be carried into the soft water tank.

　　CUnstable water pressure in the feed water can lead to insufficient water replenishment in the salt tank, insufficient salt absorption, and inadequate forward washing. Any of these factors can cause the hardness of the effluent after regeneration to exceed the standard, affecting the water quality of the soft water tank.

　　DWhen there was very little salt in the salt tank, it was not added in time, resulting in poor regeneration effect on a certain occasions.

　　EImproper operation led to the closure of the feed water valve during a certain regeneration process.

: 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.
