Research on the Method and Device for Generating Gaseous Ionic Mercury
In the monitoring of total mercury in flue gas such as coal-fired power plants,due to the calibration and calibration of the detection system,as well as the determination of the conversion efficiency and lifespan of the mercury form conversion device,combined with the characteristics of ion mercury standard gas,it is necessary to generate ion mercury standard gas on the monitoring site.This article studies the method of evaporating liquid mercury chloride and designs a set of ion mercury standard gas generation de-vice.The device is integrated into the monitoring system for total mercury concentration in flue gas,with high integration,low cost,and can be linked with the system to achieve automatic calibration and calibration.The experiment shows that compared with the Hov-aCAL gas distribution instrument,due to the lack of external connection pipelines,the loss of mercury chloride is reduced,and the generated gas accuracy is higher,Can completely replace external gas distribution instruments.
