摘要：An apparatus for economically recovering char, oil and fuel gas from vehicletires is disclosed, for either whole tires or physically fragmented tires. The tires may bewashed to remove dirt and road film. The tires are dried and preheated with super-heatsteam. The hot tires are pyrolyzed to partially devolatize a major portion of thehydrocarbons and produce a char that can be separated from the steel and fiber glass.The char may be subsequently pyrolyzed with microwaves that elevate the tiretemperature and devolatize the remaining hydrocarbons from the char as gas. The hotgases are cooled and partially condensed. The uncondensed gas is used as fuel. Thecondensed oil is sent to storage. The solid residue from the tire pyrolysis is substantiallychar, fiberglass and steel. The char is mechanically separated from the glass and steel.Alternately, the char and the glass and steel are separated by dumping the hot mixtureinto a water quench tank. The mixture is cooled. The char floats to the water surface andis removed. The glass and steel sink to the bottom of the tank and are removedseparately. The char may be sold or burned or milled to break down agglomerates andsubsequently pelletized and bagged. The steel and glass are discarded as trash.
