Technical features of demineralized water equipment for chemical boilers
The demineralized water equipment for chemical boilers mainly combines reverse osmosis with ion exchange. By taking advantage of the selective permeability of membranes, the ions that need to be exchanged in water are displaced out. Under the action of a direct current electric field, the directional movement of ions is achieved and the purpose of deep water purification is reached. The demineralized water equipment for chemical boilers has the advantages of compact structure, advanced technology and simple operation. Beijing Yuanlai Water Treatment Equipment Co., LTD., relying on its technological, talent and scientific advantages, is committed to the research and development, production and sales of water treatment equipment. Its main products include pure water equipment, purified water equipment, softened water equipment, reverse osmosis equipment, deionized water equipment, desalinated water equipment, etc. Technical features of demineralized water equipment for chemical industry boilers: 1. It adopts reverse osmosis, ion exchange, EDI and ultrafiltration technologies as well as PLC automatic control technology
Details >The principle and control mode of fully automatic boiler water softening equipment
The principle and control mode of fully automatic boiler water softening equipment: Fully automatic boiler water softening equipment has time control mode and flow control mode. The fully automatic boiler softened water equipment is a pre-treatment device for raw water launched in response to the problem of scale formation in boilers. It can remove calcium and magnesium ions from the raw water, as well as elements that cause scale formation in boilers. The technical indicators are strictly required, and the effluent quality meets the national standards for low-pressure boiler feed water. The current application scope is getting wider and wider. (1) 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 increases
Details >Introduction to Reverse Osmosis Membrane Separation Technology and Pretreatment Process
In the practical application of reverse osmosis membrane separation technology, membrane fouling is inevitable, and the membrane fouling problem is the decisive factor affecting the stability of this technology. Therefore, studying the formation mechanism of membrane fouling and cleaning the membrane fouling are important guarantees for the normal operation of the reverse osmosis system and preventing its failure. Membrane fouling refers to the physical or chemical interaction between particles, colloidal particles or macromolecules of solutes in the feed liquid in contact with the membrane, or the concentration of certain solutes on the membrane surface exceeding their solubility due to concentration polarization, as well as the adsorption and deposition on the membrane surface or within the membrane pores caused by mechanical action, resulting in a reduction or blockage of the membrane pore size. Cause irreversible changes in the permeation flow rate and separation characteristics of the membrane. Flux attenuation and separation caused by the adsorption of pollutants, especially large molecules such as proteins, on the membrane surface and within t

Details >Installation and Operation Manual for Softener
The foundation of the installation site should be flat without any protrusions or depressions, and there should be drainage measures within 1 meter around the equipment. It is recommended to install a pipe filter on the inlet pipe to prevent particles such as stones and welding slag from entering the valve body. Before use, the pipeline needs to be flushed to prevent the valve body from being blocked and the resin from being contaminated. The inlet and outlet pipes of the valve body are installed correctly. "IN" is the inlet and "OUT" is the outlet (or installed according to the inlet and outlet marks). Both the inlet and outlet must be equipped with union joints and valves, and the inlet valve must not be closed. It is recommended to install a bypass valve to ensure a water supply during maintenance. The water distributor and pipes should be installed properly to ensure that the water flow direction of the valve body is correct under all working conditions. The power supply should be connected near the control valve and ensure stable power supply for 24 hours. (220V, 50Hz) 6 salt tanks are placed near the resin tank

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.
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 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.
