Abstract

Provided is a portable particle cutter quick calibration device and a calibration method thereof. The portable particle cutter quick calibration device is characterized in that the calibration deviceis used for accurately and fast configuring and generating gas of standard particle concentration for test so as to calibrate a slicer, a key component in an air detection device; the calibration device comprises a particle storage and feeding device 15, a clean gas generator 11, a mixed cabin 7, a sample cabin 5, a cutter mounting seat 2, a beta ray test module 17, an automatic control system anda data analysis system. The portable particle cutter quick calibration device has the advantages that through a special double-cabin embedded design and a structure rationalization layout, light weight and compactness of the calibration device achieved; with each component connected through a pipeline, the gas is introduced into the beta test module in the end through the guidance of the controlsystem to realize automatic rapid detection and calibration; operation steps of the device is simplified; calibration time is shortened; efficiency is greatly improved.

Description

technical field [0001] The invention relates to a calibration device and a calibration method for a particle cutter, in particular to a portable quick calibration device for a particle cutter and a calibration method thereof. Background technique [0002] PM2.5 is a general term for solid particles or liquid droplets with a diameter less than or equal to 2.5 μm in the air, also known as fine particles or particulate matter entering the lungs. Inhalation, long-distance transmission, contains a large amount of toxic substances, has a major impact on human health, has a greater impact on air quality and atmospheric visibility, and seriously pollutes the atmospheric environment. [0003] "Measurement Gravimetric Method for PM10 and PM2.5 in Ambient Air" stipulates that the instruments used to monitor the mass concentration of atmospheric particulate matter are mainly atmospheric particulate matter samplers and monitors, which are divided into manual analysis methods and automati...
