The innovation and application of β radiation in direct reading detection of soot concentration
The direct reading detection of soot concentration directly applies the β-ray attenuation princi-ple to detect the concentration of solid substances in gaseous substances.It is suitable for not only on-site immediate detection of soot concentration discharged by fixed pollution resources,but also immediate mo-nitoring of particulate concentration in special gas environments.Based on the β-ray ionizing radiation at-tenuation theory,a soot detection gun is specialized with a heating vaporization module,which deals with the interference caused by supersaturated water vapor.The gun is convenient to carry and use.And the detection is accurate and fast.Through experiments,the data is stable and reliable,which verifies the feasibility and effectiveness of the new technology.
