Detailed Description

1.Product overview:

The continuous emission monitoring system(Ultra-low) is suitable for monitoring the continuous exhaust gas emissions of various boilers. It adopts the direct extraction method to continuously monitor the concentration of particulate matter, sulfur dioxide (SO2) concentration, nitrogen oxide (NOx) concentration, oxygen (O2) content, measurement of parameters such as flue gas temperature, flue gas pressure, and flue gas flow rate. It can be connected to the computer of the higher-level environmental protection department through the network, and the environmental protection department can easily and quickly call monitoring data.

2.System composition

• Continuous monitoring system for smoke composition
• Particle concentration detection system
• Traffic detection system
• DAS system

3.Technical characteristics

• High measurement accuracy of the system;
• Using UV differential technology to measure SO2 and NO without being affected by other interfering gases such as water vapor;
• The measurement results are not affected by fluctuations or attenuation of light source energy;
• The measurement principle ensures that the zero point of the instrument has basically no drift;
• Adopting German original imported condensers and adopting unique phosphoric acid addition technology, the loss of SO2 is avoided;
• Adopting PLC control, with high degree of automation and low maintenance workload;
• Modular system structure design, flexible configuration;
• Strong anti-interference performance of the system;
• The system is easy to operate and maintain;
• High accuracy of system data collection;
• Low monitoring lower limit, suitable for online monitoring of ultra-low emission gaseous pollutants.
