Abstract

The present invention is a centrifugal sampler of atmospheric particles, wherein the structure comprises a gas suction pump, a particle cutter, and a speed adjustable motor, wherein the particle cutter comprises a centrifugal blade wheel, a multi-seam stator and a closed bearing, and the centrifugal blade wheel can perform high speed rotation around the axis line of the multi-seam stator. According to the present invention, the centrifugal sampler can be used for quantitative measurement of the total suspended particles (short for TSP) in the air, the PM10 value, the PM2.5 value and any PM values, provides real-time monitoring data of pollution sources for Environmental Protection Bureau and monitoring enterprises, and has characteristics of simple structure, low cost, easy processing, small volume and easy use compared with the past samplers; and with the single sampler, a variety of air quality indexes can be measured, and good practical application values are provided.

Description

technical field [0001] The invention relates to a centrifugal sampler for quantitatively measuring PM2.5, PM10, TSP and any PM value in the air. Background technique [0002] At present, large areas of smog in major cities in my country have caused serious public concern about air quality. At the same time, the government is paying more and more attention to the increasingly frequent air pollution. The Chinese government has just released the revised "Ambient Air Quality Standards", adding "PM2.5" monitoring indicators, and "PM2.5" also began to appear in the government work report for the first time. The Beijing Municipal Government requires the Environmental Protection Bureau to "improve environmental monitoring capabilities, build a PM2.5 monitoring network, launch an atmospheric control plan focusing on PM2.5, and further improve air quality." [0003] For this reason, the environmental protection department needs to constantly sample and monitor the air quality index o...
