Abstract

The invention relates to the technical field of garbage treatment systems, in particular to a comprehensive utilization process of municipal solid waste incineration slag. The process realizes recovery of metal substances in the slag through production processes of primary screening, manual screening, primary magnetic separation, primary crushing, secondary magnetic separation, jigging separation, drum screening and shaking table screening. Magnetic metal and non-ferrous metal in the slag are screened and recovered in a wet recovery manner, the process design is reasonable and efficient, the metal with utilization value in the slag can be recovered to the maximum extent, and the problem of resource waste in the past is solved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment systems, in particular to a process for comprehensive utilization of municipal solid waste incineration slag. Background technique [0002] In the municipal solid waste incineration power generation, the slag is the by-product of domestic waste incineration, including the incineration residue remaining on the grate and the particles falling from between the grate. The slag is composed of slag, bricks, glass, ceramics, stones, metals and organic matter, etc. If the slag generated by the incineration power plant is sent to the landfill as general solid waste, it will increase the demand for landfill storage capacity, and There is a certain pollution to the environment and soil. [0003] Therefore, there is an urgent need for a comprehensive utilization process of municipal solid waste incineration slag, which can effectively separate metal substances from slag and prevent soil from being ...
