In order to meet increasingly strict environmental requirements, emission sources such as coal-fired power plants need to achieve "ultra-low emissions", that is, the concentration of particulate matter needs to be stably controlled below 10mg/m ³ or even 5mg/m ³. However, traditional particulate matter monitoring methods have significant errors in the low concentration range, making it difficult to accurately reflect actual emission levels. Therefore, higher precision monitoring methods are urgently needed.

In this context, ultra-low dust detectors using technologies such as laser forward scattering have emerged. This instrument has the following characteristics:

High precision measurement: The measurement error is less than 1mg/m ³, and the resolution can reach 0.1mg/m ³, which can accurately monitor ultra-low concentration emissions.

True constant velocity sampling: Through the use of fans and variable frequency control systems, sampling synchronized with actual flow rate is achieved to ensure sampling representativeness.

Full process high-temperature tracing: During the sampling process, the flue gas temperature is kept adjustable between 150-300 ℃, effectively preventing condensation and adsorption, ensuring the authenticity and reliability of the data. Optical detection: Using a small angle forward scattering laser measurement unit, it has sensitivity to low concentration particles.

The application of such instruments helps enterprises to monitor the concentration of particulate matter emissions in real time, continuously, and accurately, providing reliable data support for environmental supervision and enterprise self-control. It is not only a necessary technical guarantee for achieving ultra-low emissions, but also in line with the current national environmental policy direction of continuously promoting pollution prevention and strengthening precise monitoring.
