基于紫外差分吸收光谱法同时监测烟气汞和二氧化硫浓度的实验研究
Experimental Study on Simultaneous Monitoring of Flue Gas Mercury and Sulfur Dioxide Based on UV Differential Optical Absorption Spectroscopy
摘要
Abstract
There are strict rules for SO2 and mercury emissions from stationary sources in the latest emission standard of air pollutants for thermal power plants.. The paper mainly study on the concentration retrieval of the single SO2, single Hg0 and their gas mixture by using of continuum source. Studies have shown that for single SO2, Fourier transform filtering is better than the least squares method;For single Hg0, the maximum value at the characteristics wavelength is superior to the peak area method; For the gas mixture, after retrieving the concentration of SO2 with the Fourier transform filtering, then using the concentration relationship curves to retrieve the Hg0. The results show that, for gas mixture, the retrieval error of SO2 is less than 5%, however, the exist of SO2 will cause a greater interference to Hg0 , the retrieval error of Hg0 is more than 20%.关键词
