The invention relates to a technology for breaking, sorting and recycling household garbage
incineration slag. The technology comprises the following steps: by utilizing
gravitational potential energy and using water as a medium and circulating flow, vertically arranging an
iron removal device, a hopper, a breaker, a
magnetic separator, a jigger, screening equipment, a
slag finished product collection tank, a
sedimentation tank and the like which are equipment for treating the household garbage
incineration slag in every link from high to low; injecting water and the garbage
incineration slag into the breaker so as to form a
material flow, obtaining slag materials with fine particles, light
mass and optimized components through the breaker, the jigger and the screening equipment under the action of material
gravity flow, filtering through the collection tank and the
sedimentation tank and directly transporting the dried fine-grained slag finished product to a finished product warehouse finally; and reblending clear water obtained after
sedimentation and
filtration and the garbage incineration slag
raw material so as to be recycled. The technology has the advantages that the
exertion of
gravitational potential energy is facilitated in a material treatment process, and the friction
heat energy of the materials and the equipment is reduced; and the dust
fog pollution in the treatment process is reduced, and environments are protected.
