The development status of China's ozone generators will be promising in the future


In 1840, the German scientist Schubein identified an odorous gas produced during the electrolysis and spark discharge test as O3 and named it ozone. The characteristics and functions of ozone began to enter the field of scientific research, and it was discovered that its broad-spectrum sterilization After the effect, it gradually entered the stage of industrial production and application.

In 1902, the world's first large-scale water plant using ozone treatment technology was established in Paderborn, Germany. At present, the ozone process has been widely used in developed countries such as Europe, America and Japan. The purified tap water can be directly consumed; 1937 In ‧ the world’s first commercial swimming pool using ozone treatment was opened in the United States. At present, ozone has become the designated water disinfection method for Olympic water competitions; the United States began to use ozone technology to treat domestic sewage in the 1960s and 1970s. In 1975, the United States More than 1,000 sets of ozone devices have been installed in sewage treatment plants. In recent years, developed countries have successively established large-scale ozone advanced treatment sewage treatment plants. For example, in Japan, sewage is used as reclaimed water after advanced ozone treatment in water-scarce areas; 1982 Bottled water began to use ozone for sterilization. At present, almost all mineral water and pure water manufacturers are equipped with ozone equipment. The International Ozone Association (IOA) established in 1973 has become a platform for ozone research and application promotion. By the end of the twentieth century, the industrial application of ozone was very common, and it was widely used in drinking water treatment, sewage treatment, pulp bleaching, intermediate synthesis, textile decolorization, spice synthesis, waste tire treatment, disease treatment, storage and transportation and other fields.

Overview of the development of China's ozone generator industry

China's ozone technology started late. In the mid-1970s, domestic research and development of ozone technology began; in the 1990s, with the promotion and application of ozone disinfection technology for mineral water and pure water, the pharmaceutical industry used ozone for air sterilization. , And the application of small household ozone generators have promoted the development of China's ozone industry. After 2000, China's industrial large-scale ozone equipment manufacturing technology has achieved a lot of results. Major breakthroughs have been made in the key technologies of large-scale ozone generator manufacturing such as ozone discharge tubes, fuses, and medium and high-frequency power supplies. The successful development of 3kg/h, Large-scale intermediate frequency ozone generators such as 10kg/h, 20kg/h, 50kg/h, 80kg/h, 100kg/h, 120kg/h, etc., have gradually upgraded China's ozone technology to the international advanced level. In 2010, the implementation of "Ozone Generator CJ/T322-2010 for Water Treatment" brought China's ozone generator standards into line with international advanced standards, and played an important role in the improvement of the overall technical level of China's ozone industry and the regulation of the market. After years of development, China’s ozone system equipment manufacturing technology level and market scale have been greatly improved, and it is used in municipal water supply, municipal sewage, industrial wastewater, flue gas denitrification, fine chemicals, swimming pool disinfection, space disinfection, beverages and food industries. It is widely used.

With the rapid development of China's economy and the strengthening of environmental protection, the ozone industry will usher in a period of rapid development. However, China's ozone industry needs to be further improved and standardized. First, product specifications and performance indicators need to be further improved to meet the market's demand for large, high-performance ozone equipment; secondly, the integration of ozone equipment, system supporting levels and system control levels need to be improved, and application technology research and development needs to increase investment. Expand the application field of ozone and seek more market space. Finally, market competition needs to be further regulated to avoid vicious competition in the low-end market of small and medium-sized ozone generators, and encourage ozone equipment manufacturers to actively participate in the international high-end market competition.
