Description
Technical field
The present invention relates to and belong to solid waste resource recovery field of comprehensive utilization, particularly relate to the resource utilization method of one way of life waste incineration slag sorting tailings.
Background technology
Domestic garbage burning electricity generation is used widely in China, its advantage is: make rubbish subtract appearance more than 70% after burning, can solve current garbage loading embeading cost of land high, the problems such as landfill capacity requirement cannot be met, waste incineration produce high-temperature fuel gas recovering energy source and second stage employ.Dregs of incinerator is the byproduct that Refuse Incineration Process produces, and mainly comprises residue on fire grate and from the particulate matter dropped between fire grate, its output accounts for the 20%-30% of crude waste quality.Due to the terminal that rubbish is metallics in social life, fine grain size slag is considered as ore dressing raw material, adopt current dry method or wet processing metal (as iron, aluminium, copper, zinc, good fortune, lead and gold and silver) wherein can be sorted out, this for reduce slag environmental impact, ensure that the normal circulation circulation of metallic element in physical environment is significant, be also the general way of current waste incineration tailings pre-treatment.But, be no matter the slag dry separation technique that is representative with fragmentation-magnetic separation-vortex flow sorting process, or with the slag wet split technique that fragmentation-magnetic separation-gravity-floatation technique is representative, all there is the residue tailings process problem after sorting.Tailings after sorting is used as the direct landfill of general solid waste by most waste incineration field, and this not only wastes resource and also takies a large amount of soil.Therefore, how realizing its mass-producing utilization is the current great difficult problem faced.
About the utilization of waste incineration slag, domestic have part investigator to be studied.Patent of invention CN1331796A discloses a kind of method utilizing domestic waste incineration residue to produce masonry cement, and physicals all can reach masonry cement GB/T3183-2003 standard, but the consumption of dregs of incinerator is not high, is less than 15%.Patent of invention CN101386480A discloses a kind of method utilizing domestic waste incineration residue to produce Portland clinker, the basis of existing new dry process rotary kiln stove makes improvements, produce Portland clinker with slag to replace partial clay and Wingdale, but the unwanted component (alkali, chlorine etc.) that dregs of incinerator is brought in raw material still can cause negative impact to clinker burning process after treatment.Patent of invention CN1558030A discloses the method that one way of life waste incineration slag makes civil engineering structural sheet, using dregs of incinerator as gathering materials for the base course of town road or alternative Tu Yuan as covering material for house refuse landfill site, the part heavy metal that slag contains very easily causes secondary pollution, potential impact is existed on environment, and these heavy metal substances and the wherein free calcium oxide of content instability and free magnesium, the intensity of pavement construction material can be had influence on again, poor durability from physical chemistry aspect.
At present, China is in materials for wall period of reform, and cellular concrete product becomes with its lightweight, insulation (heat insulation), the good characteristic such as energy-conservation can one of the material of instead of clay brick.What most foamed concrete gelling material adopted is cement and flyash is that major ingredient is produced, and after the complete aquation of cement, building block product drying shrinkage is large, and preparation cost is higher.Give full play to the activity of waste incineration tailings; by waste incineration sorting tailings fine powder and cement mixing; coordinate admixture again; prepare porous material foamed concrete; this can provide new way for producing high quality and low cost foamed concrete; also the tailings mass-producing fully realizing garbage slag sorting utilizes, and not easily produces secondary pollution, is achieve many things at one stroke.
