Description

A kind of resource utilization method of domestic waste incineration residue sorting tailings
Technical field
The present invention relates to belong to solid waste resource recovery field of comprehensive utilization, more particularly to a kind of domestic waste incineration Slag sorts the resource utilization method of tailings.
Background technology
Domestic garbage burning electricity generation is used widely in China, the advantage is that:Make rubbish volume reduction 70% after burning More than, can solve the problems such as current garbage loading embeading cost of land is high, can not meet to fill capacity requirement, height caused by waste incineration Warm combustion gas recovering energy source and secondary use.Dregs of incinerator is byproduct caused by Refuse Incineration Process, is mainly included on fire grate Residue and account for the 20%-30% of crude waste quality from the particulate matter to be dropped between fire grate, its yield.Because rubbish is society The terminal of metallics in living, fine grain clinker is considered as ore dressing raw material, can be by it using current dry or wet technique In metal (such as iron, aluminium, copper, zinc, good fortune, lead and gold, silver) sort out, this for reduce clinker environmental impact, ensure Normal circulation circulation of the metallic element in natural environment is significant, and the tailings pretreatment of waste incineration at present is general Way.But the clinker dry separation technique either using broken-magnetic separation-vortex flow sorting process as representative, or with broken Broken-magnetic separation-gravity-floatation technique is the clinker wet split technique of representative, the remaining tailings process problem after sorting be present. Most waste incineration fields directly fill the tailings after sorting as general solid waste, and not only waste of resource also takes up a large amount of soil for this Ground.Therefore, how to realize that its scale utilizes is the great difficult problem currently faced.
On the utilization of waste incineration slag, the country has part researcher to be studied.Patent of invention CN 1331796 A discloses a kind of method that masonry cement is produced using domestic waste incineration residue, and physical property can reach masonry cement GB/ T3183-2003 standards, but the dosage of dregs of incinerator is not high, less than 15%.The A of patent of invention CN 101386480 disclose one The method that kind produces Portland clinker using domestic waste incineration residue, on the basis of existing new dry process rotary kiln stove Make improvements, substitute part of clay and lime stone with clinker to produce Portland clinker, but dregs of incinerator is brought into Harmful constituent (alkali, chlorine etc.) in raw material still can adversely affect to clinker burning process after treatment.Patent of invention CN 1558030A disclose a kind of method of making civil work engineering structure layer using domestic incinerator slag, using dregs of incinerator as Gather materials for town road base course or substitute Tu Yuan as covering material for house refuse landfill site, part that clinker contains weighs Metal easily causes secondary pollution, exist on environment it is potential influence, and these heavy metal substances and wherein content is unstable Fixed free calcium oxide and free magnesium, influence whether the intensity of pavement construction material, durability again in terms of physical chemistry Difference.
At present, China is in materials for wall period of reform, and cellular concrete product is with its lightweight, insulation (heat-insulated), section The good characteristics such as energy, which turn into, can substitute one of material of clay brick.Most foam concrete binder materials are using water Mud and flyash are major ingredient to produce, and building block product drying shrinkage is big after the complete aquation of cement, and it is higher to prepare cost.Give full play to rubbish The activity of tailings is burned, waste incineration is sorted into tailings fine powder and cement mixing, then coordinates additive, prepares porous material foam Concrete, this can provide new way for production high quality and low cost foam concrete, also fully realize garbage slag sorting Tailings scale utilizes, and is not likely to produce secondary pollution, is to achieve many things at one stroke.
The content of the invention
Problem to be solved by this invention is to overcome the shortcomings of the prior art, there is provided a kind of domestic waste incineration residue Sort the resource utilization method of tailings.
Concrete scheme is as follows:
A kind of resource utilization method of domestic waste incineration residue sorting tailings, comprises the following steps:
Fine grinding:Remaining tailings progress after the sorted iron of garbage burning factory clinker, aluminium, copper, zinc, gold, silver metal is levigate, Convection drying is carried out using heat smoke, obtains sorting tailings micro mist;
It is prepared by compound:Sorting tailings micro mist is subjected to dry type mixing with cement, early strength agent in mixer;
It is prepared by foam:Foaming agent is diluted with water, with foaming mechanism for foam with standby;
It is prepared by cement slurry:Fiber, water reducer and water are uniformly dispersed in agitator, add the compound prepared, Obtain cement slurry;
