Introduction to the online monitoring system for hot and wet flue gas

1、 Product Introduction:

The TK-1000H continuous monitoring system for flue gas emissions, independently developed by Shandong Xinze Instrument Co., Ltd., is an extraction based wet thermal online CEMS solution based on years of technical accumulation in typical industrial scenarios such as thermal power plants and steel plants. This system adopts modular design and integrates gaseous pollutant monitoring subsystems (SO ₂ NOx）、 The particulate matter monitoring subsystem, flue gas parameter monitoring subsystem (temperature/pressure/flow rate/humidity/oxygen content), and intelligent control and data acquisition processing subsystem are integrated, which can accurately monitor key parameters such as SO ₂, NOx, O ₂ (standard state/wet basis/dry basis/converted value), particulate matter concentration, temperature/pressure/flow rate at fixed pollution source emission outlets, and support expandable monitoring of CO, CO ₂ and other indicators, fully meeting the requirements of HJ75-2017 and HJ76-2017 national standards.

The system innovatively integrates' full process high-temperature tracing+ultraviolet differential absorption spectroscopy (DOAS) technology+laser pre scattering dust measurement technology 'to achieve synchronous measurement of multiple parameters such as SO ₂, NO, O ₂, particulate matter concentration, temperature/pressure/flow rate/humidity. Real time uploading of data to the environmental monitoring platform through intelligent data acquisition terminals (or dynamic control devices) ensures the integrity and timeliness of monitoring data. The equipment adopts a standardized cabinet layout, and all core units are integrated into a professional monitoring station building, which has the advantages of stable operation, convenient maintenance, and economic efficiency.
