The FID-VOCs online monitor for fixed pollution sources is an online monitoring system developed by Tiande for industrial volatile organic waste gas (VOCs) from fixed pollution sources. The product has passed the China Environmental Protection Product CCEP certification and has a test report from the Environmental Monitoring Center.
The system consists of five basic parts: gaseous pollutant monitoring system (total hydrocarbons, methane, non-methane total hydrocarbons, benzene series (optional)), flue gas parameter monitoring system (temperature, pressure, oxygen, humidity, flow rate), system control and data acquisition and processing system, sampling system pretreatment system, calibration and auxiliary system. The sampling probe is responsible for exhaust gas sampling. The built-in stainless steel filter element is used to filter the dust in the exhaust gas. It is accompanied by high-temperature heating throughout the pipeline to avoid condensation points in the exhaust gas in the sampling pipeline.
The system can improve the processing and management ability of industrial VOCs waste gas pollution monitoring data, and provide decision-making basis for environmental planning and environmental assessment.
1. The product fully complies with the requirements of HJ 1286-2023 technical specifications for continuous monitoring of non-methane total hydrocarbons in exhaust gas from fixed pollution sources.
2. There is no cold spot in the system: the whole process of heating is traced to ensure that there is no cold spot in the whole process of sample gas sampling, and no condensation will occur, which will affect the actual measured value of sample gas;
3. Supports data docking between equipment and enterprise central control system, and comes with a standard modbus protocol output serial port.
4. Support the requirements of system data direct connection to data acquisition instruments.
5. It adopts imported AFP ten-way diaphragm valve, which has low maintenance and long service life. Key chromatography accessories are optional imported from China;
6. It has automatic backflushing, cleaning, and remote calibration functions. The hydrogen machine has automatic water adding function and is simple to maintain;
7. For special explosion-proof areas, customized explosion-proof models can be upgraded.
8. Obtain the latest national standard CCEP environmental protection product certification and the applicability test report of the environmental monitoring station.
It is suitable for online monitoring of organic waste gas concentration before/after organic waste gas treatment facilities. It is widely used in industries that emit organic waste gas such as environmental monitoring, petrochemical industry, steel smelting, industrial surface coating, spraying, semiconductor and manufacturing industry.
