Electrodialysis devices are suitable for water treatment in industries such as electronics, pharmaceuticals, chemicals, thermal power generation, food, beer, beverages, printing and dyeing, and painting; It can also be used for physical and chemical processes such as concentration, purification, and separation of materials; Electrodialysis can also be used for the treatment of wastewater, waste liquid, and sewage, as well as the recovery of precious metals, such as nickel from electroplating waste liquid. Mainly suitable for electrodialysis power supply, it is a specialized equipment designed to provide the required DC electric field for electrodialysis process.
Product features:
1. Our company has introduced international pulse width modulation technology specifically designed for the characteristics of electrodialysis power supplies: newly upgraded line control technology, intelligent soft switch synchronous rectification technology, which saves 25% -28% energy compared to thyristor rectifiers; And ensure continuous operation at full load for 365 days and 24 hours, with energy-saving structure and circuit design, small size, light weight, high efficiency, fully sealed, anti-corrosion, moisture-proof, waterproof, shockproof, radiation resistant, and anti-interference.
2. Networking cost: Adopting digital networking technology, equipped with RS-485 communication interface, one set of twisted pair cables can connect all power equipment, and can directly connect to PLC or industrial computer, reducing a large number of analog output modules, optical output modules, power transmitters and cables;
3. This control system uses a highly reliable 32-bit microcontroller without a core to achieve the conversion of communication protocols between PLC and power supply, completely solving the problem of protocol mismatch between PLC and power supply. Due to the direct reading and writing of PLC memory, developers can focus on the development of the production line by simply setting the corresponding parameters in the corresponding memory units of the PLC, greatly reducing research and development pressure;
4. This control system can support HOSTLINK of Omron PLC, QNA of Mitsubishi PLC, and RTU protocol of Siemens, and can also be customized according to PLC;
5. Adopting advanced direct digital frequency synthesizer (DSP) waveform generation technology, the output frequency has high stability, good continuity, and high measurement accuracy.
6. Touchscreen operation display, easy to operate and user-friendly, 7-inch color screen display, all parameters displayed at a glance.
Principle analysis: The electrodialysis power supply provides a direct current electric field for the electrodialysis process of water or other substances. In the direct current electric field, the selective permeability of the anion exchange membrane and cation exchange membrane is utilized to allow some ions to migrate through the ion exchange membrane to another part of the water, thereby diluting some of the water and concentrating the other part, thus achieving water purification.
