Development trends in the field of environmental monitoring in 2020
In recent years, ZHENG has continuously increased its support for the ecological environment monitoring industry, and provided double guarantees in terms of policy and finance. Since the "Twelfth Five-Year Plan", it has resolutely declared war on pollution, fully promoted the prevention of air, water, and soil pollution, and continued to increase ecological environmental protection. After that, the National WU Academy issued the "Thirteenth Five-Year Plan for Ecological Environmental Protection". The central government allocated 11.2 billion yuan, 14 billion yuan, and 9.1 billion yuan in special funds for the prevention and control of air, water quality, and soil pollution. In the past year, strictly implement the policy requirements such as the "Three-Year Action Plan to Win the Blue Sky Defence Warfare" and the "Working Plan for the Tightening of Pollution Control of Diesel Trucks", guided by the spirit of the 19th da Efforts should be made on emission improvement, comprehensive treatment of "scattered pollution" enterprises and clusters, pollution control of diesel vehicles, pollution control of agriculture and rural areas, and protection and restoration of the Yangtze River water resources.
In terms of system reform, the mode of national assessment, national monitoring, and enterprise self-monitoring and supervision is implemented, environmental monitoring is strengthened, and third-party operations of environmental monitoring are encouraged, and the environmental monitoring industry is encouraged to develop and develop high-tech monitoring products. Nowadays, the environmental monitoring system has been continuously improved, and the degree of marketization has been gradually improved. In the field of gas, water and soil, the three-dimensional layout of the sky, the earth, and the sky, the distribution of network points have been developed, and the development of the environmental monitoring market has accelerated.
In the year of technological development, the improvement of the networked informational environmental monitoring system can improve the current problem of incomplete environmental monitoring content. The establishment of a networked monitoring system can facilitate the LIAN department between environmental monitoring departments and can timely Understand the probability and status of similar environmental problems in various regions.
By 2020, China's environmental problems will mainly be the pollution of the atmosphere, soil and water resources, as well as land desertification and soil erosion. Therefore, by 2020, industries and enterprises in the field of environmental monitoring need to further increase, expand, and upgrade special product technologies At the same time, it is necessary to further optimize the ecological network system, build a unified ecological environment monitoring big data management platform, and even establish an ecological environment monitoring system that covers the nation ’s integrated space, earth, air and big data multi-functional area. In 2020, the market scale and market development space of the environmental monitoring industry are also huge.
The main components of centrifugal Air Compressor used to compress gas are high-speed rotating impeller and diffuser with gradually increasing flow area. In short, the working principle of centrifugal compressor is to work on the gas through the impeller. In the flow channel of the impeller and the diffuser, the mechanical energy is converted into the pressure energy of the gas by the centrifugal pressure boosting effect and the speed decreasing pressure expanding effect.
The advantages of centrifugal air compressor
Centrifugal compressor can obtain such a wide range of applications, mainly than the piston compressor has the following advantages.
1. Centrifugal compressor has large gas volume, simple and compact structure, light weight, small unit size and small footprint.
2, balanced operation, reliable operation, high operation rate, less friction parts, because the spare parts need less, less maintenance costs and personnel.
3, in the chemical process, centrifugal compressor on the chemical medium can do absolutely oil-free compression process.
4, centrifugal compressor is a rotary motion machine, it is suitable for industrial steam turbine or gas turbine direct drag. For general large-scale chemical plants, byproduct steam is often used to drive industrial steam turbines, which provides the possibility of comprehensive utilization of heat energy
