碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 103 === The study keynote for optimal operation parameters and ambient PM Impact reduction for street sweeper to USEPA AP-42 paved roads sampling . How to reduce the sweeper in 2014 Taiwan&;#39;s current major metropolis of six street dust load, and that most of the road street dust load distribution in A and B, and draw soil and street dust about 1: 5 to configure sweepers simulate road grade street dust of reference The study results for different level road sweepers optimum operating parameters of the street dust removal efficiency are:when the A-class road speed is 8 km / hr, the blower speed 1,500 RPM, water content is 0.8 L / min, the total street dust removal efficiency is 74.21%;when the B-class road speed is 8 km / hr, blower speed is 1,500 RPM, water content is 0.8 L / min, the total street dust removal efficiency is 74.47%; when the C-class road speed is 8 km / hr, blower speed is 3,000 RPM, water content is 0.8 L / min, the total street dust removal efficiency is 87.05%, When the sweepers were working, fugitive dust and road speed, blowers, sprinklers are in inverse proportional , so the faster the road speed、the greater the blower speed、the more the amount of watering, fugitive dust also fewer. And this study used sweepers improved combination of prevention and control element inside the particulate matter (stainless steel , stainless steel mesh, sprinklers), when in actual street sweeping can improve their perimeter about 35% TSP and PM10 impact (with η the index value of the counter).
