Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of secondary treatment and reuse of industrial waste. It specifically involves the crushing of domestic waste incineration slag, the removal of heavy metals such as iron and copper in the slag and other impurities, and the slag separation process. Background technique [0002] With the development of the economy, municipal solid waste is increasing at an annual rate of 8-10%. Using waste incineration power generation technology, domestic waste is incinerated at a high temperature of 1000°C to form slag. Although the volume of slag is only 10% to 30% of the original domestic waste, the problem of slag accumulation has increasingly plagued power plants. The waste tailings of the quarry - stone chips are the main aggregate for the production of concrete porous bricks. Due to the limited mining of the quarry, the supply of stone chips is in short supply, and it is urgent to find alternative products and resour...
