TREATMENT OF MUNICIPAL SOLID WASTE

摘要

An apparatus and process for the separation, recovery and recycling of municipal solid waste (MSW) in which hot water (48) is added to shredded and homogenized MSW 2 as it enters a rotating feed preparation drum (34) equippe d with internal lifter blades (36). The blades (36) and rotation of the drum (34) cause mixing and pulping of the MSW before discharge into a rotating thermal processor (56) also equipped with lifter blades (58) and cone sectio n (64), and in which the moist MSW 2 is heated by heating the hot gases in the processor by a flame from burner (62) which converts the moisture in the MSW to steam. The steam permeates through the MSW as it is turned and lifted in the thermal processor (56), causing further pulping.
