Analysis of the Working Principle of Boiler Softened Water Equipment and the Causes of excessive water hardness

Analysis of the Working Principle of Boiler Softened Water Equipment and the Reasons for excessive water Hardness: Commonly used boiler softened water systems consist of three parts: the controller section, the cation resin exchange section, and the salt (sodium ion) regeneration section. Cation exchange technology is the working principle of the boiler soft water system. Beijing Yuanlai Boiler softening water equipment is mainly applied to steam boilers, steam generators, coal-fired heating furnaces and water exchange heating boilers, etc. The working principle of 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 absorbs a certain amount of calcium

Daily maintenance of laboratory ultrapure water machines

First, let's briefly understand the ultrapure water machine. Whether it is imported or domestic equipment, the principle is the same. Tap water is pre-treated through a precision filter core and an activated carbon filter core to filter out particles such as sand and adsorb odors, making the tap water cleaner. Then, it is purified and desalinated through a reverse osmosis device. The purified water is stored in a water storage tank. The water quality can reach the national Grade III water standard, and at the same time, the wastewater produced by the reverse osmosis device (also known as "concentrated water") is discharged. Reverse osmosis pure water undergoes deep desalination treatment through a purification column to obtain first-grade water or ultrapure water. If the user has special requirements, ultraviolet or microfiltration, ultrafiltration and other devices should be added after the ultrapure water to remove residual particles, heat sources and other substances in the water.

The consequences of improper operation of the reverse osmosis edi device

The reverse osmosis edi device is an industrial high-purity water equipment that combines reverse osmosis technology and EDI technology. It has excellent working efficiency and water quality. During the application of this equipment, if the operation is improper, the performance of its main component, the reverse osmosis membrane, may be damaged. Therefore, to avoid such problems, the following points should be particularly noted. There are usually two situations where residual gas in the permeation equipment operates under high pressure, forming air hammers that can damage the membrane: A. After the equipment is emptied, when it is restarted, the pressure is rapidly increased without completely discharging the gas. The remaining air should be completely discharged at a pressure of 2 to 4bar before gradually increasing the pressure for operation. B. When the joint between the pretreatment equipment and the high-pressure pump is not well sealed or leaks (especially when the microfilter and the pipeline after it leak), when pretreatment

FLECK softening centralized controller from the United States

The fully automatic water softener of the American FLECK centralized softening controller features a piston-type valve core that not only has outstanding hydraulic performance but is also sturdy, wear-resistant and corrosion-resistant. The lead-free brass valve body is harmless and has a long service life. Fully automatic water softeners can be classified into various series such as time-controlled type, flow-controlled type, and continuous soft water supply system type. They come in multiple combination forms including single-valve single-tank, single-valve double-tank, double-valve double-tank in parallel, and large multi-valve multi-tank in series, meeting the different water usage requirements of boiler soft water equipment. The working principle of the "Artuzu" fully automatic water softener (sodium ion exchanger) of the American AUTOTROL multi-way valve controller: The sensor flowmeter on the outlet pipe of the sodium ion exchanger randomly collects the output water volume information and promptly inputs it into the computer. After storage and calculation, it issues instructions to the multi-way servo valve or solenoid valve for operatio

Time-type and flow-type fully automatic water softening equipment

Our company adopts the multi-way valve control system of American companies such as Artuzu and Fulaike, and designs and produces the fully automatic water softening equipment in combination with national conditions. It is widely used in the preparation of industrial and civil softened water, such as boiler water supply, heating, supplementary water for air conditioning systems, and good domestic water, etc. The fully automatic softening system mainly consists of multi-way valves, controllers, resin tanks and salt tanks. The multi-way valve is designed with multiple channels in the same valve body. Technical parameters of the softener: 1) Raw water hardness; 6[H+]mmol/L, that is, 300 mg/L (calculated as CaCO3). When the raw water hardness is between 6 and 12[H+]mmol/L, 3) It is recommended to adopt two-stage softening or appropriately reduce the effluent production. 4) When the raw water hardness

: 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.
