Abstract

The invention discloses an atmospheric particle black carbon aerosol quality concentration monitoring instrument, including an air monitoring room. The upper end of the air monitoring room is connected with a suspended absorption electromagnetic iron. The top of the air monitoring room is provided with a LED light source array. The air monitoring room is communicated with an air inlet. The bottompart of the air monitoring room is a glass plate, which is equipped with a breathable window. A quartz filter paper belt is arranged under the air monitoring room. Two reference and measurement photoelectric detectors are arranged under the quartz filter paper belt. One detector is used for reference and another detector is used for test. With an optical attenuation method adopted, the invention has the advantages of good real-time performance, high precision and low cost, improved automation degree, time and labor-saving performance and all-weather automatic continuous operation. The continuous and real-time on-line monitoring of the atmospheric particle black carbon aerosol is ensured.

Description

technical field [0001] The invention relates to the field of environmental protection monitoring, in particular to an instrument and method for conveniently and online monitoring the mass concentration of atmospheric particulate matter-carbon black aerosol. Background technique [0002] Carbon black aerosol has a very important impact on regional and even global climate and environmental changes. Its particle size is generally less than 2.5 microns, and it is more harmful to human health than PM10. Therefore, it has gradually become the detection object of meteorological departments and environmental protection organizations in various countries. At present, the international methods for detecting carbon-containing aerosols mainly include: [0003] A. Turbidity measurement method: This method uses a traditional "turbidity coefficient" sampler (CoefficientOf Haze tape sampler, referred to as COH) to collect aerosol at a certain point for a fixed period of time, and then measu...
