The invention provides a waste plastic sorting device and method, and relates to the technical field of waste plastic recycling. The technical problem that existing sorting equipment cannot effectively complete fine sorting of waste plastics is solved. The waste plastic sorting device comprises a crushing device, a precipitating and cleaning device, an electrostatic sorting device and a conveyingdevice, and the crushing device, the precipitating and cleaning device and the electrostatic sorting device are connected through the conveying device. The precipitating and cleaning device is arranged at the downstream, of the crushing device, on a material conveying line, can remove impurities in crushed materials, separate flame retardant plastics and non-flame retardant plastics, and performspreliminary sorting on the non-flame retardant plastics; and the electrostatic sorting device further selects, classifies and collects the non-flame retardant plastics, raw materials are sequentiallysubjected to crushing, prec
