Patent number: 10258912Abstract: Highly efficient particulate collectors, such as for dust and street debris collected by a mobile street cleaning vehicle, with very low pressure loss are disclosed. One embodiment uses a specially contoured passage to separate the solid particles from particulate-laden gas stream by rapid directional change at a throat region. By using the Venturi effect at the accelerating zone communicating with a gas return channel from the particulate retaining chamber, a small amount of the gas will be recirculated from the deposit zone to help move and retain the separated particles in a confined collection receptacle.Type: GrantFiled: April 14, 2015Date of Patent: April 16, 2019Assignee: FEDERAL SIGNAL CORPORATIONInventor: Xiaolun Huang
