Project cases - mature, stable, safe and reliable

In the field of electrolytic brine chlorine production, Shanghai Saiyi Water Treatment Technology Co., Ltd. has undertaken a number of influential and large-scale international projects and accumulated rich domestic and foreign engineering experience. For example: the electrolytic chlorine production equipment of the 1.3 million-ton water plant in the south of St. Petersburg, Russia, with a chlorine production capacity of up to 320kg/hr (the world's largest in the field of water plants), the 800,000-ton water plant in the north of St. Petersburg, and the 50kgx6 electrolytic chlorine production equipment (water plant) on Chongming Island in Shanghai The world's largest single equipment in the field), the first large-scale electrolytic chlorine production equipment 20kgx3 loaned by the World Bank in Uzbekistan and Tajikistan, Shanghai Changxing Island 100,000-ton water plant 20kg (The largest on-site sodium hypochlorite generator water plant in China), Wenzhou Dongxiang 120,000-ton tap water plant, etc. Shanghai Saiyi is currently the only company in China with operating performance of more than 100,000 tons of water plants, and has been operating stably for many years.

In the field of electrolytic seawater chlorine production, Saiyi Company has undertaken the chlorine production and disinfection system 130kg/h*2 of the Middle East 2x1000MW power plant, the 1040 power plant project in India 120kg/h*3, the 2x1000MW second power plant project in Zhejiang Taizhou 50kg/h*2, and the CNOOC Shanghai LNG project 72kg/h*1, PetroChina Dalian LNG project 25kg/h*2, Dalian LNG Phase II project 25kg/h*2, CNOOC Guangdong LNG project 20kg/h*3, Philippines Siemens Power Plant seawater electrolysis project 15kg/h* 1. Singapore Middle East project 8kg/h*1.

In 2012, Saiyi Company used its unique electrolysis technology to achieve Class A E. coli emission standards when the amount of chlorine added to the effluent water from the sewage plant was only 1/4 (1.5ppm) of the national standard, successfully completing the Yiwu The on-site sodium hypochlorite preparation and disinfection renovation project of the 70,000-ton sewage plant of the Water Quality Treatment Center, and in 2014, it continued to undertake the standard improvement and renovation projects of 5 other sewage plants in Yiwu, including the 150,000-ton and 50,000-ton sewage plants, thus making a breakthrough in the field of safe sewage discharge. sexual progress.

Technological advancement

Relying on the scientific research and talent advantages of Tongji University, our company develops and produces complete sets of sodium hypochlorite equipment with the following characteristics:

1) Modular design

The electrolytic tube adopts a modular design, and modules can be added or reduced according to the different amounts of sodium hypochlorite required. This can not only meet user needs, but also ensure the maturity and perfection of the finalized module production process and ensure product quality.

2) Repolar structure

The composite electrode connection method has very few connectors in the entire structure, which reduces the heat generated on the connectors, greatly reduces the salt consumption and electricity consumption in the production of sodium hypochlorite, and has a positive effect on reducing by-products.

3) Transparent design of electrolytic tube

The electrolytic cell shell is made of high-strength transparent organic glass, which allows real-time observation of the electrolysis process and electrode surface, making it easy to judge the electrode status, determine the pickling cycle, and ensure electrode safety.

4) Fully automatic operation

A complete automatic control system ensures that the production of sodium hypochlorite can be completed without human operation. A PLC automatic control system is installed, equipped with an on-site touch screen and a convenient operation interface.

5) Advanced electrode arrangement

The special electrode arrangement ensures that the hydrogen produced by the electrode escapes quickly on the electrode surface, increases the apparent conductivity of the electrolyte, reduces energy consumption, and improves electrolysis efficiency.

6) Gradient push flow energy-saving technology

The salt water flows in the electrolytic tube in a push-flow manner, and the concentration of the salt water changes in a gradient during the electrolysis process, which can significantly improve the electrolysis efficiency, reduce the temperature rise of the electrolyte, reduce power consumption by 18%, and reduce salt consumption by 14%.

7) Instant hydrogen discharge technology

During the production process of sodium hypochlorite, the hydrogen gas produced by electrolysis is quickly discharged from the electrolytic tube through the instant hydrogen discharge technology in the tube, ensuring the good condition of the electrolyte in the electrolytic tube and preventing electrode exposure. This can not only improve the current efficiency of sodium hypochlorite production, but also improve the performance of the electrode. service life.

8) Patented sodium hypochlorite electrode

The continuous operating life of the electrode is guaranteed to be more than 5 years, and the electrolysis current density is lower than similar products at home and abroad, which is more conducive to improving electrolysis efficiency and extending the life of the electrode.

9) Long pickling cycle

Using refined salt and built-in softener, the pickling cycle is extended to half a year to one year, which improves electrolysis efficiency, reduces maintenance workload, and extends electrode life.
