Product details
WCKJ-VOCs-3000 Fixed Pollution Source Volatile Organic Compounds Online Monitoring System
Product Introduction
The WCKJ-VOCs-3000 fixed pollution source volatile organic compound online monitoring system consists of three basic parts: volatile organic compound monitoring subsystem, exhaust gas parameter monitoring subsystem, and system control and data acquisition subsystem. It can monitor gas organic pollutants such as methane, total hydrocarbons, and non methane total hydrocarbons (expandable benzene derivatives (benzene, toluene, xylene, etc.) in exhaust gas, as well as parameters such as humidity, temperature, pressure, and flow rate of exhaust gas. The tested exhaust gas undergoes dust removal through a sampling probe, heat tracing through a heat tracing tube, and enters the high-temperature chromatographic analysis module (GC-FID) for analysis and measurement. For the monitoring of high boiling point organic pollutants in exhaust gas, it can effectively avoid adsorption losses during sample collection and transmission, ensuring excellent performance and stability from sample sampling, analysis, data upload, and maintenance.
Product advantages
The overall scheme design of the total heat method is suitable for harsh working conditions such as high temperature, high humidity, high concentration, and high dust. From sampling to analysis, high-temperature tracing is used throughout the process, effectively reducing sample loss and ensuring the authenticity and reliability of data;
The sampling pipeline is made of PTFE or inert metal weakly adsorbing material, with a heat tracing temperature of 120 ℃ (adjustable), effectively reducing the loss of sample adsorption caused by the sampling pipeline;
The pre-treatment method complies with the US EPA and domestic organic waste gas testing standards, and the method is stable and reliable;
A sample pretreatment device with self-cleaning function can effectively treat impurities such as fine particles and water vapor in the sample, avoiding damage to the analysis system;
Customizable sampling probes to meet the installation and usage requirements of exhaust pipes of different materials and specifications;
The automatic airtightness testing function of the system can effectively perform airtightness testing, ensuring the accuracy and reliability of the test results;
Using gas chromatography (FID) analysis method, in line with international and domestic measurement standards, in addition to conventional monitoring factors, specific detection factor application methods can be provided for development;
It has various application designs such as conventional and positive pressure explosion-proof, and can be applied to stable and reliable operation under different safety requirements such as explosion-proof zone 0;
Having multiple data interfaces to meet the collection needs of different users for monitoring data;
Can support one to many application modes;
