Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The residual residue of domestic waste incineration and power generation enters the sand collection tank through rolling screening, magnetic separation, flotation, and selection. The specific process is: Rolling screening: Put the residue of domestic waste incineration and power generation into the rolling screen to remove large pieces of scrap iron such as iron wire and iron sheet, as well as unburned large domestic waste, and the finer residue falls into the silo under the rolling screen; Magnetic separation: The finer residue from the silo enters the first crusher through the conveyor belt, and an iron remover is installed in the middle of the conveyor belt before entering the first crusher for magnetic separation to remove the scrap iron in the finer residue ; Flotation: The residues and scraps from the first crusher enter the jig for flo...

Abstract

A comprehensive utilization method of residue from municipal solid waste incineration generating is provided. A brick-making method is as below: stirring residue, stone chips and cement to form a mixture, distributing the mixture to a mold by a distributing machine, to pre-molding the mixture by a hydraulic vibration machine to form preformed bricks, distributing a surface material mixed from white cement, sand and a pigment on the surfaces of the preformed bricks, and pressing the mixed material and surface material by the hydraulic vibration machine to obtain bricks. A method for producing a non-reactive cement mixed material is as below: 1) drying: drying the residue from municipal solid waste incineration generating by a dryer; 2) iron removal: removing iron in the dried residue by a de-ironing separator; 3) rolling: rolling the residue after iron removal by a rolling machine; and 4) grinding: grinding the residue after rolling by a grinding machine. The present invention has the following beneficial effects of: 1, expanding the comprehensive utilization ways of residue from municipal solid waste incineration generating; 2, solving the quality problem caused by high moisture content in non-reactive mixed material in brick-making or cement production, and 3, saving energy and reducing emission.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of domestic waste incineration power generation residue. Background technique [0002] After sorting, screening, and cleaning, the residue after domestic waste incineration for power generation can be widely used as building materials and roadbeds. [0003] Domestic waste incineration power generation residue is the residue left after urban domestic waste incineration for power generation. At present, domestic waste incineration power generation is used as a measure of environmental protection, and the remaining slag is comprehensively utilized, mainly after magnetic separation of scrap iron. The slag is used to make bricks or as an inactive mixed material for making cement. [0004] At present, there are more than 140 household waste power stations in my country, and the number is still increasing. Household garbage is inexhaustible and inexhaustible. The residue of domestic waste incin...
