With the development of modern industry, air pollution has attracted more and more attention. All kinds of pollution in the air will not only cause a series of economic losses, but also be closely related to human health and the entire natural environment. CEMS system came into being, which is widely used to monitor the concentration and total emission of gaseous pollutants, and is an indispensable link in the combustion and emission process.

Concept of cems system
CEMS is the abbreviation of Continuous Emission Monitoring System, which refers to the device that continuously monitors the concentration and total emission of gaseous pollutants and particulates emitted by air pollution sources and transmits the information to the competent department in real time. It is called "automatic flue gas monitoring system", also known as "continuous flue gas emission monitoring system" or "online flue gas monitoring system". CEMS consists of gaseous pollutant monitoring subsystem, particulate matter monitoring subsystem, flue gas parameter monitoring subsystem and data acquisition and processing and communication subsystem. The gaseous pollutant monitoring subsystem is mainly used to monitor the concentration and total emissions of gaseous pollutants SO2, NOx, etc; The particle monitoring subsystem is mainly used to monitor the concentration of smoke and dust and the total emissions; The flue gas parameter monitoring subsystem is mainly used to measure the flue gas flow rate, flue gas temperature, flue gas pressure, flue gas oxygen content, flue gas humidity, etc., and to calculate the total emissions and convert the relevant concentrations; The data acquisition, processing and communication subsystem consists of a data collector and a computer system. It collects various parameters in real time, generates dry, wet and converted concentrations corresponding to each concentration value, generates daily, monthly and annual cumulative emissions, completes the compensation of lost data, and transmits the report to the competent department in real time. Smoke and dust test has developed from cross flue opacity dust meter and β - ray dust meter to plug-in backscatter infrared light or laser dust meter, as well as forward scattering, side scattering and electricity dust meter. According to different sampling methods, CEMS can be mainly divided into three technologies: direct measurement, decimation measurement and remote sensing measurement.
Flue gas: It refers to the waste gas pollution generated by the enterprise in the production process, including SO2 NOx、HCL、CO、CO2、 Particulate matter includes oxygen content, etc.
Discharge: It refers to the process in which enterprises discharge the waste gas generated from production into the atmosphere.
Continuous: It means that the emission of the enterprise is a continuous process and the real-time monitoring of the system is also a continuous process.
monitor: It means that the system can monitor whether the harmful substances in the exhaust gas discharged by the enterprise exceed the standard in real time and automatically transmit the data obtained from the real-time monitoring to the superior department at the same time.
System: It means that the hardware and control software of the product are integrated.
Application of cems products:
The application of this product must have the certification certificate of the national environmental protection department and the measurement production license, etc. At present, it is mainly used in the continuous monitoring of various industrial exhaust emission sources, including thermal power plants, waste incineration power plants, chemical plants, paper mills and other industries, with strong applicability, and can measure SO2 concentration, NOx concentration CO concentration, particle concentration, oxygen content, temperature and humidity, pressure, flow rate and other gas parameters.
