Atmospheric environment monitoring CEMS flue gas online monitoring system

CEMS, the online system for continuous emission of flue gas, refers to a complete system that continuously monitors the concentration of gaseous pollutants and particulate matter emitted by air pollution sources and the total amount of emissions, and uploads the data to the environmental protection department in real time. With the improvement of economic level and environmental protection awareness, all walks of life are paying more and more attention to the emission of air pollutants. CEMS flue gas online monitoring system has begun to be widely used in all walks of life to realize remote real-time monitoring of pollution source emissions.

introduction:

CEMS flue gas online monitoring system adopts direct extraction method, which mainly includes four parts: gaseous pollutant analysis system, dust particle analysis system, flue gas parameter analysis system and data processing system. It can monitor dust particles, sulfur dioxide (SO2), and nitrogen oxides online. (NOx), oxygen (O2), flue gas temperature, flue gas pressure, flue gas flow rate and other data.

Among them, sulfur dioxide and nitrogen oxides are analyzed in real time using the NDIR non-dispersive infrared principle, and the oxygen content is analyzed using the mechanical dumbbell paramagnetic principle. Both detection principles can be calibrated online with standard gas to ensure the accuracy of the values. Dust particles are measured directly in the flue using the principle of laser backscattering, which is fast and easy to use.

The cloud platform of the CEMS flue gas online monitoring system can process, store and upload the detection data remotely, which is convenient for customers to process and record, and monitor pollution emissions in real time.

Application areas:

CEMS flue gas online monitoring can be widely used in thermal power plants, waste incineration plants, cement industry, chemical industry, petroleum industry, iron and steel enterprises, various industrial boilers, various industrial kilns, and other industrial processes that generate fixed emissions of polluting gases Source monitoring.

System functions:

1. Real-time monitoring of sulfur dioxide, nitrogen oxides, oxygen, dust, flue gas temperature, pressure, and flow rate values.

2. Comes with pretreatment system and probe blowback system, which can effectively remove all kinds of interference factors and is suitable for complex working conditions.

3. Online calibration without disassembly.

4. Various software supports to realize various data processing functions.

5. Continuously monitor the particulate matter, SO2, NOx and other pollutants in the flue gas. At the same time, it can measure the flue gas flow rate, pressure, temperature, humidity, oxygen content and other data, and automatically record the total amount of pollutant discharge and discharge time , And through PSTN, GPRS, CDMA and other communication means to transmit the monitoring data to the management department to achieve remote real-time monitoring of pollution source emissions.

With the acceleration of urbanization, urban waste has become a serious problem. To dispose of garbage by landfill takes up a lot of land. At the same time, because many garbage is not easy to decompose, it will cause long-term pollution to the environment. Many places in our country need to build waste incineration power plants to process waste on the one hand, and use waste heat on the other to provide clean energy. The composition of waste gas emitted by waste incineration is very complex. The gas composition that usually needs to be analyzed is HC, SO2, NO, N02, NH3, CO, CO, H2O, 02, etc. Weihai Jingxun Changtong CEMS online monitoring system can analyze exhaust gas, which is of great significance to industrial production and environmental protection.
