1. Rigorous environmental compliance requirements
With the strict implementation of regulations such as the "Air Pollution Prevention and Control Law" and the "Technical Specifications for Continuous Monitoring of SO₂ and NOₓ Emissions from Fixed Pollution Sources" (HJ 75-2017), enterprises are required to upload real-time monitoring data of flue gas pollutants to the environmental protection department. The accuracy of the data is directly linked to the pollutant discharge permit and environmental protection rating. According to the HJ 1045-2019 standard requirements, the ultraviolet absorption method has become the preferred technology for portable monitoring of SO₂ and NOₓ, and the high-temperature ultraviolet flue duct analyzer achieves continuous monitoring through fixed installation. The detection data must meet the strict indicators of "accuracy ≤ ±2% FS, response time ≤ 20 seconds, data validity rate ≥ 90%". Non-compliant enterprises will face a maximum fine of one million yuan.
2. Exclusive adaptation for harsh operating conditions
Traditional infrared analyzers are prone to interference from water vapor and dust in high-temperature flue ducts, while electrochemical sensors have problems such as high-temperature failure and short lifespan. The high-temperature ultraviolet analyzer has three core advantages:
The ultraviolet wavelength (190~400nm) can penetrate high-dust and high-humidity flue gas and is not interfered by background gases such as CO₂ and H₂O;
The core components use high-temperature-resistant materials and heat insulation design, which can directly adapt to wide temperature conditions of 200℃~1600℃, without the need for complex cooling pre-treatment;
It has excellent corrosion resistance and can withstand the erosion of acidic gases such as SO₂ and HCl in the flue duct, avoiding monitoring errors caused by component aging.
