Abstract

The invention discloses a dilution sampling probe which comprises a gas guide pipe, a gas guide branch pipe, an internal filter, a pneumatic constant-current device, a return pipe, a current limiting pipe, a diluting assembly, a gas path pipe, an external filter, an electric executor, an aluminum shell, a constant-temperature assembly and an installing box body. According to the dilution sampling probe disclosed by the embodiment of the invention, the precision of measuring the concentration of pollutants in a gas sample, especially the precision of measuring the concentration of pollutants in a gas sample with low concentration of the pollutants can be increased, and the accuracy of a measuring result can be verified in real time through calculating the adding standard recovery rate.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring and sampling, in particular to a dilution sampling probe capable of dynamically adding standards to collect flue gas emissions from fixed pollution sources. Background technique [0002] Improving ambient air quality is the top priority of environmental protection tasks, and the continuous emission of flue gas from fixed pollution sources is one of the main sources of polluting ambient air. Therefore, online monitoring of flue gas emissions from fixed pollution sources is an effective means to improve air quality . [0003] At present, the most widely used CEMS (Continuous Emission Monitoring System) sampling technology is the dilution sampling method, that is, the sample gas is diluted with pure nitrogen or dry and clean air in a heated sampler, and the dew point of the diluted gas It is reduced to the point that there will be no condensation when it is transported by a non-heat...
