摘要: The vacuum-blowing cleaning system, utilizing positive and negative pressure mixed-delivery theory, has been adopted for the road sweeper vehicle. To enhance solid particle separation performance to evaluate motion characteristics of inhaled particles under different structural parameters, gas-solid flow in system was investigated by using computational fluid dynamics (CFD) technology. influence main parameters on grade dust collection efficiency average detention time determined, such as suction-inlet diameter, inclination angle, front baffle angle. And interplay between them also investigated. In addition, a model built, based uniform design (UD) multiple regression analysis (MRA), subsequently verified via experiments. results revealed that have significant performance. angle exerted highest, second-highest, lowest influence, respectively. Furthermore, interaction among influenced levels were determined inlet diameter/baffle angle/baffle diameter/inlet interactions, highest (i.e., 96.10%) short chamber realized following conditions: diameter angle: 200 mm 110°, respectively, 105°.
