Product details
The online monitoring system for heavy metals in flue gas is a crystallization of experience in the development and manufacturing of X-ray fluorescence (XRF) technology. The instrument combines flue gas particulate matter dilution sampling technology and isokinetic sampling technology to reduce the moisture and temperature in the flue gas to a certain temperature, and the particulate matter is automatically enriched on the roll filter membrane. The detector and X-ray fluorescence digital multi-channel analysis technology are used to detect the X-ray fluorescence intensity generated by heavy metal particles under X-ray excitation, and the concentration of heavy metals in flue gas particulate matter is calculated through signal intensity and volume conversion. Realize automatic continuous monitoring of the content and total emissions of dozens of heavy metals such as lead, mercury, tin, chromium, arsenic, etc. in flue gas.
It can simultaneously measure up to 20 types of heavy metal elements, and the measured elements can be customized
Generally, analysis results can be obtained every 15 minutes
Non destructive non-destructive testing technology allows for sample archiving for subsequent laboratory quality control analysis
Automatic quality control, equipped with internal standard elements to automatically check the long-term stability of the system
Professional radiation protection treatment to achieve comprehensive protection
Compared with the reference method, it has higher detection accuracy
Unmanned, easy to operate, easy to maintain, with almost no other daily consumables except for the filter belt
The system has self diagnostic alarm, automatic measurement and automatic calibration functions
Can simultaneously detect more than 20 heavy metal elements such as lead, copper, chromium, zinc, etc., and automatically convert cumulative emissions
