Introduce Guangzhou gaohui Power Technology Co., Ltd. is located in Panyu District, Guangzhou City, the economically developed Pearl River Delta (the geographical center of Dawan District, Guangdong, Hong Kong and Macao). The company focuses on the design and manufacturing of rectifier power supply equipment and high-frequency power supply, and is applied to PCB electroplating, hardware electroplating, continuous electroplating, hard chromium electroplating, rare earth smelting, oxidation, electrophoresis, electrolysis, electrochemical water treatment and other fields.


Electric flocculation driving power supply
Basic principle: a variety of electrochemical reactions are generated by electrochemical methods, mainly including electro oxidation, electro reduction, electro flocculation and electro flotation.
Operating cost: 2-5 yuan / ton of water (determined according to different water quality)
Installed power: 5-10kw / t water
Water treatment capacity: 1-30 T / h (more than one will operate in parallel)
Main uses: it can remove turbidity, decolorization, algae, fluorine, iron and other total metal ions in water supply treatment, as well as sterilization and disinfection; It plays a role in flocculation sedimentation, decolorization, COD degradation, ammonia nitrogen, silicon removal, etc. in drainage treatment, especially some difficult wastewater treatment. It has an incomparable effect. At present, it is widely used in reinjection water treatment of fracturing flowback fluid of oil wells, anodic oxidation decolorization and phosphorus removal water treatment.
Electrochemical scale absorption device

1. Scale adsorption prevents pipe blockage, improves heat exchange efficiency and saves energy consumption.
2. Dissolve and peel the old scale and improve the circulating water flow of the pipeline.
3. Absorb floating iron ions to prevent pipeline rust.
Wide range of use:
Horizontal injection molding machine, water-cooled air compressor, die casting machine, industrial ice water machine, refrigerator, central air conditioner and other circulating water units. It is used for descaling cooling circulating water in injection molding, die casting, food, medical treatment, chemical industry, casting, auto parts, electroplating, aluminum oxidation, steel-making plants, power plants, sewage plants, people's hospitals, subway stations, large shopping malls and so on.
Electrocatalytic oxidation driving power supply
Process introduction
Electrocatalytic oxidation technology is an advanced oxidation technology. Under normal temperature and pressure and catalytic induction, the catalyst coating on the surface of anode plate has a series of physical and chemical interactions with organic pollutants in wastewater. At this time, active intermediates (primary oxidants such as H2O2, · oh and ClO -) and one or more new ecological coagulants will be generated to produce a variety of physicochemical effects such as catalytic oxidative decomposition, coagulation, adsorption, complexation and replacement, so as to degrade the target pollutants.
Technical features
1. Low operation cost: through this technology, there is no need to add expensive oxidant, which greatly reduces the cost;
2. No secondary pollution: the system has almost no sludge and no secondary pollution;
3. Strong oxidation ability: the strong oxidizing hydroxyl radical produced by electrocatalytic oxidation can oxidize most pollutants without selectivity;
4. Automatic control: electrocatalytic oxidation technology, automatic control, unattended, easy to manage.
Scope of application
It is applied to high difficulty wastewater zero discharge projects in thermal power plant, chemical industry, papermaking, steel, printing and dyeing and other industries.
Sodium hypochlorite electrolysis power supply
Working principle of sodium hypochlorite generator
Working principle of sodium hypochlorite generator equipment: a series of electrochemical reactions occur under the action of positive and negative electrodes in the electrolytic cell to generate sodium hypochlorite solution. Sodium hypochlorite is a strong oxidant. It generates hypochlorite ion in aqueous solution and generates sodium hypochlorite through electrolytic reaction. It has the same oxidation and disinfection effect as other chlorine derivatives.
Scope of application:
1. 2-5% brine electrolysis
2. Connected to seawater electrolysis
Electrode reaction:
Anode: 2Cl -- 2e → Cl2 ↑
Cathode: 2h + + 2e → H2 ↑
Total reaction: NaCl + H2O electrolysis → NaClO + H2 ↑
