Abstract

The invention discloses a dust cutter calibration system. According to the dust cutter calibration system, a wind tunnel is used for simulating a uniform dust environment, and a collection head of the dust cutter is arranged in the dust environment; when collection efficiency of the dust cutter is calibrated, the same particle diameter spectrometer which is calibrated standardly is used for measuring concentration of dust in dust-containing gas from which dust is not cut and concentration of dust in dust-containing gas from which dust is cut, and accuracy of detection results can be improved. Via the calibration method, not only can the collection efficiency of the dust cutter be calibrated, dust concentration tester and the particle size spectrometer can also be calibrated.

Description

technical field [0001] The invention relates to a calibration system, in particular to a calibration system of a dust cutter. In addition, the invention also discloses a calibration method of the dust cutter. Background technique [0002] With the continuous development of industry, the living environment of human beings has been destroyed, and the air pollution situation is severe, and the suspended particles in the air can cause haze weather. In particular, inhalable dust is the most harmful to the human body. Respirable dust refers to particulate matter with an aerodynamic equivalent diameter of 10 μm or less, which is commonly referred to as M10. In addition, particulate matter with an aerodynamic equivalent diameter of 2.5 μm or less in the ambient air is also called fine particulate matter, and is also called PM2 in daily life. 5. [0003] At present, there are three methods widely used in the world to determine dust concentration: gravimetric method, β-ray absorptio...
