Th-890 continuous emission monitoring system (CEMS) is suitable for real-time continuous monitoring of pollutants emitted from fixed industrial sources such as metallurgy, energy, chemical industry, cement, etc The newly issued "technical requirements and testing methods for continuous monitoring system of flue gas emission from stationary pollution sources" (HJ / t76-2017), technical specification for continuous monitoring of flue gas emission from stationary pollution sources (HJ / t75-20017), technical specification for automatic monitoring information transmission and exchange of environmental pollution sources (HJ / t352-2017), etc.
The system adopts modular design of industrial instruments, standard electrical control cabinet is selected, and the system structure realizes electrical separation and independent control.
In view of the high humidity condition, two ways of flue gas dehumidification can be adopted at the same time: adding acid into cooler and dehumidification by drying tube, and the change of dehumidification efficiency can be monitored in real time. The pretreatment subsystem has no cold end and condensation in the whole process, and provides solutions for various interference substances
The analyzer can be equipped with ordinary or ultra-low range to meet the requirements of different monitoring accuracy
The analysis system is equipped with dynamic gas distribution device, which can realize manual, automatic and remote system zero point, full point and simple zero point correction. The upper and lower computers monitor and store the system process and monitoring data, providing preventive maintenance and system self diagnosis data support for users. The model selection provides diversified system configuration, which can be configured according to the actual needs.
