      At present, the lack of fresh water resources in China, the rapid development of industry led to serious water pollution, increasingly serious water pollution not only reduces the use of water function, but also further exacerbated the contradiction between water shortage, a direct impact on people's living environment. China's drinking water treatment and sewage treatment in the field of widely used ozone generator and supporting systems there are dependent on imports, expensive, technical services are not in place and other issues.

      Recently, the "Twelfth Five-Year" special water "drinking water safety technology system research and demonstration" theme by Qingdao Guolin Industrial Co., Ltd. commitment to "non-glass medium large-scale ozone generator equipment development and industrialization issues" passed acceptance. Acceptance experts believe that the subject carried out a large-scale ozone generator key devices and remote operation and maintenance platform and other aspects of the study, successfully developed a large ozone generator non-glass dielectric discharge unit, IF high-power high-voltage transformers and power and other key equipment, formed Non-glass medium ozone generator sets, large-scale production capacity, the establishment of a large ozone generator series of production base, the annual production capacity of 150 sets (4000kgO3 / h). Among them, the equipment localization rate of 94.7%, the core components completely domestic, discharge tube repair rate of <0.5%, significantly improved product competitiveness. Products in more than 100,000 tons of drinking water depth of treatment projects in the application of more than 6, exceeding the intended target.

The study of autonomous ozone equipment is significant

      After several decades of development, foreign ozone technology is increasingly mature, the degree of integration of ozone generator and the system supporting the level of higher and higher. At present, the highest output of a single outdoor ozone generator has reached 250kg / hour, the ozone concentration can reach 14wt% about 210mg / L). At the same time, due to the use of computer intelligent control, new media formulations and a reasonable power supply match, making the same concentration of power consumption is getting lower and lower. China's ozone technology started late. In recent years, along with the growth of the domestic application market and the country's strong support for domestic equipment, the emergence of a number of professional research ozone generator core technology and key components of the enterprise, so that China's ozone technology has been rapid development. "Ozone activated carbon" is one of the most effective solutions to the current water pollution situation, water quality requirements of one of the most efficient. With the implementation of new standards for drinking water and the state's emphasis on new drinking water processes, large ozone generators will have a huge market demand. However, for a long time, large-scale water plant has been difficult to advance the domestic ozone equipment into a high threshold. Drinking water industry used by the large-scale ozone generator was a few foreign manufacturers monopoly, foreign equipment, there are high prices, high maintenance costs, technical services are not in place and other issues, the study of independent ozone equipment is imminent.

New prototype to fill the relevant blank

      In the ozone equipment industry base, the reporter saw this new type of ozone generator prototype. According to the company chairman Ding Xiangpeng introduction, the device uses a new type of ozone discharge tube series of ozone generator unit patented technology. The prototype has reached the project requirements, to fill the gaps in the manufacture of large-scale ozone generator in China non-glass medium. Ozone generator from the ozone chamber, high power ozone dedicated power supply, automatic control instruments, PLC programmable logic controller man-machine interface control system and other components to liquid oxygen as the gas source, through the ozone chamber non-glass dielectric discharge tube High-voltage alternating electric field, oxygen molecules excited by high-energy electrons, collision with each other to synthesize ozone.

      At the same time, the research of the ozone generator core device technology, through the core device innovation and integration applications, developed in line with the project requirements of 20 ~ 80kg / h ozone generator equipment, the formation of ozone generator products, developed ozone generator and Ozone system on-line detection and remote diagnosis technology, developed two sets of supporting the enterprise standard.

Key technology research and development to improve equipment efficiency

      Project breakthrough a number of key technologies: First, the ozone discharge tube using low carbon ferrite embryo material, medium glaze formula to join the modified nano-materials and high borosilicate glass composition, improve the sintering process, a substantial increase in non-glass dielectric ozone discharge Processing accuracy of the pipe. Second, by connecting the connecting rod on the connecting rod, so that the ozone generator in each discharge tube of the metal tube body can be directly connected with the connecting rod directly connected to effectively eliminate the virtual connection between the discharge tube, Reducing the connection resistance, a substantial increase in discharge efficiency. Thirdly, the self-developed high-power intermediate frequency inverter power supply for capacitive load ozone generator is developed, and the efficiency and stability of the ozone generator are improved by adjusting and designing the parameters of the inverter resonant circuit.

      In addition, the subject independently developed a large-scale ozone generator power control and monitoring unit, the hardware using large-scale digital logic circuits and high-speed microprocessors dual-core structure, the software developed a power control class IP core and embedded real-time operating system based on power monitoring And control procedures to ensure the reliable operation of the ozone system. The ozone sensor is successfully developed, so that the ozone equipment can be implemented on-site and remote control, and the sensor data can be collected in real time and the cloud platform is stored in stages to improve the information level of the equipment. The ozone system online control and service platform is established. Is conducive to explore new business model.

Promotion has good prospects

      In the country to vigorously promote environmental protection and energy conservation policies to encourage and guide the environmental protection project for large-scale ozone equipment facing enormous market demand and broad prospects for development. In addition to the deep treatment of drinking water, sewage recycling, chemical enterprise tail gas treatment and other large ozone generator has a great demand.

      Professor Wang Zhansheng said: "The need to strengthen the norms of the entire industry, strengthen the training of talent." China Municipal Engineering South China Design Research Institute Vice President Deng Zhiguang said: "The project developed a large non-glass Ozone generator with ozone production, high degree of automation, reliable operation, high efficiency, etc. should further increase product promotion and promotion, and further improve product performance, speed up system integration, and gradually replace imported equipment to meet China's drinking water treatment, Environmental management and other engineering applications, and actively explore overseas markets, good products export.
