Introduction to VOCs Online Monitoring System for Fixed Pollution Sources

　　1、 Product Introduction

The TK-1200 pollution source VOCs continuous monitoring system independently developed by our company adopts advanced full process high-temperature heat tracing pretreatment+gas chromatography technology (GC)+hydrogen ion flame detection method (FID), mainly used for real-time monitoring of organic matter emissions from various industrial pollution sources. This series of online gas chromatography analyzers has stable and reliable performance, high degree of automation, wide detection range, and can measure multiple parameters such as total hydrocarbons (THC), methane (CH4), non methane total hydrocarbons (NMHC), benzene derivatives, etc. It can continuously and real-time track and monitor the concentration and emission rate of VOCs, and transmit all monitoring parameters to industrial computer software and user DCS systems. It can be used through data acquisition instruments and environmental protection department data systems. Communication.

twoTechnological advantages

• Environmental product certification certificate CCEP, testing report, and the system meets the technical requirements of national standard HJ1013;

• The online chromatograph adopts injection pressure balance technology, with minimal sample injection error and accurate measurement;

• Adopting multi-stage precision dust removal, the pipeline is made of weak adsorption material with self-cleaning function, which can effectively backwash and clean impurities such as particles in the sample, avoiding pipeline blockage. It is suitable for harsh conditions such as high temperature, high humidity, high concentration, and high dust;

• Extraction sampling method, adjustable heat tracing temperature, high temperature tracing from the self sampling probe to the analytical instrument throughout the system, temperature setting of 120-180 ℃, and no condensation in the entire gas flow path;

• The system adopts EPC technology to control the flow rates of carrier gas, air, and hydrogen, with high accuracy and good repeatability;

• The system has comprehensive alarm functions, including over temperature alarm function and main component fault alarm function;

• The system has an automatic ignition function. In the event of program interruption due to external influences or brief tripping, the system can automatically start, ignite, and resume operation after power is restored.

• The system has calibration function. The entire system calibration starts from the probe and calibrates the entire system's gas path;

• Independently developed data collection and analysis software, which can be adjusted according to the needs of enterprise users;

• The system can record, store, display, query, export, transmit, and print reports and data reports for any time period. The format should be consistent with the report format required by the environmental protection department, and historical data should be saved for at least 3 years.
