Research on Environment Materials with Soot Position Influence on SO2 Concentration Measurement

Article Preview

Abstract:

The pollutant gaseous SO2 concentration is one of the most important parameters in national atmosphere environment monitoring system with properties of environment materials. SO2 emission can be calculated through measuring SO2 concentration. The common SO2 concentration measurement method of the stationary pollutant sources is NDIR. Soot in duct can absorb the measurement light intensity and the different acceptance light intensity of the receiver is caused by soot different position, so the attenuation of SO2 measurement light intensity is increased and the SO2 emission concentration measurement data is error. The different soot position interference is studied in this paper. Simulation results show that soot difference position can interference SO2 concentration measurement accuracy. The experiment is carried on. The experiment result shows that the measurement method can on-time obtains the soot different position interference and decreases SO2 concentration measurement error.
