Methodology and Sampling Apparatus to Measure the Dust Emission from Paved Road Using Moving Vehicle

摘要

The invention neombu player to move has had an internal space, the sample is sucked from the outside; Flow meters for controlling the flow rate of an inner plenum a constant velocity by using the player is connected to the neombu, vacuum pump; A vacuum pump that is connected with the flow meter, the sample out the plenum portion to the outside; And is connected with the plenum neombu, the plenum portion sample is to take samples in the position when moved constant velocity measuring the concentration for measuring the concentration of the sample; using a mobile vehicle including a measuring emissions of road dust It relates to a system for. According to the present invention by measuring using a vehicle collected dirt being re-scattered by the tire of the moving vehicle traveling on the road can be solved the problem of the risk of traffic accidents and traffic control. ; Fugitive dust, constant suction vehicle
