In the rapidly developing 1990s of the Chinese economy, a private enterprise single handedly changed the traditional water treatment method in China, bringing enormous benefits to the society. It is Yelin International Group Holdings Limited. How did this enterprise pioneer in a field? In this episode, we have specially invited Mr. Wang Peilin, Chairman and Senior Engineer of Yelin International Group Holdings Limited (hereinafter referred to as "Mr. Wang"), to share with us this extraordinary journey.

Changing tradition, leading technology

Wang Gong's company launched a high-performance chlorine dioxide generator, the YL400 model, which attracted widespread attention in 1997. Wang recalled that this device was a specific model in the entire YL series electrolytic chlorine dioxide generator. Its technology was recognized as leading by experts from the Ministry of Construction, the Ministry of Energy, the National Environmental Protection Administration, and the Chinese Academy of Preventive Medicine in March 1993, becoming a groundbreaking product in the field of disinfection in China. This achievement quickly attracted the attention of major media outlets, with reports from People's Daily, Science and Technology Daily, Environment Daily, and others.

The drawbacks of traditional disinfection methods

Before the emergence of YL400, China's water and sewage treatment mainly relied on chemicals such as chlorine, sodium hypochlorite, and calcium hypochlorite. However, these traditional methods have many drawbacks, especially the production of trichloromethane, which is a carcinogenic substance. Chlorine dioxide disinfection can produce various disinfectants such as chlorine dioxide, ozone, and hydrogen peroxide, which have broad-spectrum bactericidal effects.

The process of exploration and innovation

Wang Gong mentioned in an interview that as early as 1988, he learned about chlorine dioxide disinfection technology through exchanges with the American electrochemical community. At that time, foreign countries had already begun to gradually adopt this technology, while China had not yet widely used it. The country launched the "2000 Technical Development Plan for Urban Water Supply Industry" in July 1993. Although it recognized the importance of disinfection technology, the corresponding technology was not yet available in China at that time.

From design institute to independent entrepreneurship

Wang Gongyuan was engaged in mine design work at the Planning and Design Institute of the Ministry of Coal Industry, but with the reform of the design institute, he chose to start his own business and devoted himself to the research and application of water treatment technology. With years of technical accumulation and a deep understanding of electrochemistry, he developed the YL series electrolytic chlorine dioxide generator in a short period of time, and passed tests by Beijing University of Chemical Technology and Beijing Municipal Health and Epidemic Prevention Bureau, proving that its chlorine dioxide concentration reached more than twice the national standard.

Solution to safety issues

The production of chlorine dioxide involves safety issues, and Wang emphasized that all electrolysis processes have the risk of explosion. Through cooperation with power plants, he designed a system to ensure safety, controlling hydrogen concentration below 1%, which is even stricter than the US standard. He stated that safety is non-negotiable and must be strictly operated in accordance with regulations to avoid any potential dangers.

Perseverance towards technology and quality

For many years, Wang Gong has always adhered to the research of technology and the control of product quality. He believes that the fast money making method is not suitable for technology-based enterprises, and strict control must be exercised over every detail of the product to ensure safety and performance. He emphasized that the promotion of technology requires comprehensive training for users to ensure they can use the equipment correctly and avoid safety accidents.

look into the future

Wang is full of confidence in the future development of the enterprise. He revealed that the company is currently developing a new electrolytic chlorine dioxide solution and plans to expand its application to more fields, including water plants and sewage treatment plants. In addition, he is also exploring the possibility of combining chemical and electrolytic methods to increase chlorine dioxide concentration, reduce costs, and minimize pollution. At the same time, he is also committed to developing new technologies and applications such as electrocatalysis and hypochlorous acid, striving for continuous innovation in the field of disinfection and purification.

summarize

Through communication with Mr. Wang, we deeply felt his relentless pursuit of technology and persistence in innovation. He is not only an outstanding engineer, but also an entrepreneur who dares to break through himself. In the future, Yelin International Group will continue to promote this spirit of craftsmanship and make new contributions to China's disinfection and purification industry. Wang Gong is committed to technological breakthroughs and the inheritance of industry research. The Chinese wastewater treatment platform created by him will also be launched this year, and he hopes to contribute more to the development of the industry.
