China's environmental problems have reached a moment of urgency. Speeding up environmental pollution control and strengthening environmental supervision cannot be merely superficial. As an indispensable new force in the management of environmental pollution, the development of the instrumentation industry and its role in it once again focused on the industry's attention. Analysis of Baosteel Instrument and Instrument Industry Environmental monitoring instruments and meters: It is a type of instrument in the field of instruments. It is a professional on-site analysis instrument that collects analytical data and obtains pollution sources and environmental background pollution. Today, China's environmental detection instruments and meters mainly include water, air and soil. After more than ten years of development, such instruments and meters have developed to a considerable extent. A number of domestic listed instrument companies, such as environmental protection, concentrating technology, Xuedilong, and Tianrui Instruments, have certain R&D capabilities.
In the field of environmental monitoring instruments, the market share of domestic enterprises is similar to that of foreign companies. The main reason is that the gap between domestic technology level and foreign countries is not obvious, and domestic enterprises have an advantage in the expansion of sales channels and after-sales services. Laboratory Analysis Instrumentation: Laboratory analysis instruments are also an important category of instrumentation. They are terminal analysis instruments that collect, analyze, and test liquid, gas, and soil samples. In the field of laboratory analysis instruments, domestic enterprises still focus on low-end products and high-end analytical instruments such as chromatography, mass spectrometry, and nuclear magnetic resonance. Most of the market is occupied by foreign companies. According to statistics, the domestic market satisfaction rate for middle and low-end instruments is 65%, and the satisfaction rate for medium-to-high-end instruments is 30%. Industrial process analysis instrumentation: industrial process analysis instrumentation, also known as online analytical instrumentation, is a general term for the automatic analysis and measurement of the composition and properties of substances in industrial production processes, with a focus on combustion control, safe recovery of waste gas, The automated analysis products required for process control and quality monitoring reflect the real-time conditions in production. Industrial process analysis instruments and meters are mainly used in petrochemical, iron and steel metallurgy, energy power, cement, building materials, biochemical pharmaceuticals, microelectronics, air separation, coking, natural gas, coal chemical industry, aerospace and other industries. Chinese online analytical instruments started earlier. In the 1950s and 1960s, there was a group of instrument manufacturers with state-owned and military backgrounds providing various types of online analytical instruments. 3, remote sensing telemetry instrumentation: the use of non-contact sensors / sensors and other non-contact technology to analyze the nature of environmental pollution, characteristics and status of the theory, methods and applications of instrumentation. These mainly include remote sensing remote sensing of air pollution, water pollution (such as ocean red tide, oil spill pollution) and pollution sources. Satellite ground receiving systems and satellite image analysis systems are also set up to analyze the current status and changing trends of environmental ecological quality.
In recent years, China's remote sensing technology has achieved certain achievements, but there is still a certain gap between the sensor and the international. Market demand for environmental protection instruments and meters industry At present, domestic environmental protection instruments and meters urgently needed include: atmospheric environmental quality monitoring instruments and automatic monitoring systems; monitoring systems for flue gas analysis instruments represented by coal-fired power stations or boilers; surface water environmental quality inspection instruments and Monitoring system; pollution source monitoring instruments and automatic control systems represented by urban sewage treatment plants and high-concentration organic wastewater. 1. Atmospheric governance: During the 12th Five-Year Plan period, the Ministry of Environmental Protection will implement eight key projects such as sulfur dioxide treatment and nitrogen oxide treatment, with a total investment of approximately RMB350 billion. For example, the newly issued "Emission Standard of Air Pollutants for Thermal Power Plants" has greatly increased the dust removal and desulphurization standards. According to a rough estimate, 70%-80% of dust removal equipment and desulfurization equipment need to be reconstructed, and over the next two and a half years will usher in a denitrification market of more than 80 billion yuan. It is expected that the market capacity for desulfurization construction during the 12th five-year plan will exceed 50 billion yuan, and the operating market will reach 32.8 billion yuan by 2015, with a compound annual growth rate of more than 50%.
2. Water management: The entire water treatment industry chain will benefit from China's 12th Five-Year Water Governance and water price increase. The lack of water and water, and the uneven distribution of water resources in space and time are inherent disadvantages. Water pollution and deterioration of water ecology are blamed on the extensive growth and control of the water. Without affecting the supply of water resources, controlling pollution, protecting and maximizing the use of available resources are the main ways to ensure water supply security. During the 12th Five-Year Plan period, China's investment in the water treatment industry will reach 800 billion, which is 113% higher than during the 11th Five-Year Period.
3. Soil management: The General Office of the State Council has issued the “Work Arrangement for Soil Environmental Protection and Comprehensive Management in the Near Future†recently. It is proposed that by 2015, we will thoroughly understand the soil environmental conditions in China, initially curb the rising trend of soil pollution, and strive to build a national soil by 2020. The environmental protection system has significantly improved the soil environmental quality in the country. Some reports pointed out that the cost of land remediation in some regions has reached billions or even tens of billions of yuan. Considering that there are real estate development needs in large, densely populated cities in China, once the market is officially launched, the market space for future soil remediation is expected to be More than 100 billion yuan.
"The changes that manufacturing is undergoing have exactly the same meaning and even greater significance as the introduction of general-purpose parts or production lines," he said. GE's global research lab (about 15 minutes away from the battery plant) is responsible for advanced technologies. Michael Idelchik of technology research said, “The future will not be the problem of extending the global supply chain connected to the major plant networks in the distant areas. It is the use of highly sophisticated new tools and new materials for small and flexible applications. The issue of manufacturing manufacturing activities.†However, the big label of the new industrial revolution is far from being without roots. The big changes that were still in the early stages are accelerating because many trends have come together: the low cost and accessibility of the massive data associated with cloud computing; the electronic sensors, microprocessors, and the ability to make machines more agile The cost of other components has fallen dramatically; advances in software and communications technology have allowed people to manage manufacturing and provide new forms of collaboration with new levels of precision. The new wave of ultra-cheap electronic sensors, microprocessors and other components mean that facilities like the factories of Heathrow's factory can do their work with little manual assistance, and a large amount of data can be collected throughout the process. Managers can receive immediate reminders of potential problems or research data to find ways to increase efficiency and improve performance.
