Description
Technical field
The utility model relates to cinder from refuse incineration renewable resource utilization technical field, especially a kind of system that utilizes cinder from refuse incineration to prepare aggregate.
Background technology
Ash is extremely similar with the substance characteristics that natural crystal gathers materials as the by product of city garbage burning, and it is rich in Na, K, and Si, Ca, Fe, principal elements such as Al, good stability, particle grading distribution are better, possess as the basic demand of material of construction use etc.Research has both at home and abroad proved that all incineration residue is the environmental friendliness alternate resources of natural building material after treatment.
Rapid economy development, quickening of urbanization process increase the output of municipal wastes year by year, and garbage incineration technology is fast, innoxious with its processing speed, subtract advantages such as holding the remarkable and recyclable heat energy of minimizing effect is developed rapidly.The tempo of the large-scale municipal solid waste incinerator of China's construction of modern is very fast, by to the end of the year 2007, and built in China and reached more than 80 in the incineration treatment of garbage factory that builds, day amount of burning away the refuse reaches more than 80,000 tons approximately.The domestic refuse of the present burning disposal of China accounts for gross output rubbish 8%.Expect 2015, the incineration treatment of garbage ratio of some large size cities will increase more than 20%, and the cinder from refuse incineration day output that produces when the time comes will reach more than 100,000 tons.In the face of the cinder from refuse incineration of enormous quantity like this, landfill disposal has occupied a large amount of soils of surrounding city, also in various degree pollution the environment of city suburbs.Thereby, how effectively to dispose these city garbage burnings by product, turn waste into wealth, be that China has one of urban Environment Protection to be solved.
Resource utilization management incineration residue, exploitation ecological environment-friendly type material of construction not only are of value to the secondary pollution of practicing thrift in a large amount of soil spaces, the control lime-ash landfill process, make the problem of outlet of bottom ash obtain substantive the solution; Can also alleviate because the structure material demand is increasing and, reduce the consumption of construction industry, and reduce the greenhouse gas emission in the common building materials production process the natural resource and the energy to the pressure that natural Mineral resources cause.Country attaches great importance to the applied research of regeneration concrete, is put into country " 15 " key scientific and technological projects.Thereby the bottom ash regenerated using substitutes aggregate and has immeasurable social effect, is the outlet that is fit to China's national situation.The technology that the research and development cinder from refuse incineration prepares the eco-concrete material has obvious practical significance.
In the development of current domestic cinder from refuse incineration regeneration conversion product; Mainly comprise: (1) concrete product with garbage-incinerating cinder and the method for manufacture thereof (patent No.: 02114714.0); It is characterized in that earlier metal sundries is removed in cinder from refuse incineration magnetic separation and screening, broken then with sieve; Be the lime-ash disinfection below 20 millimeters to the back granularity of sieving subsequently, add cement and water stirring, slurry perfusion, vapor cure and drying again; (2) also has the city garbage burning lime-ash system light-weight brick exempt from baking (patent No.: 200410009708.X); It is characterized in that it is to use the mechanical vibration extrusion molding after being moist shape by city garbage burning lime-ash powder, river sand or stone flour, quicklime calcium sulfate, cement, calcium chloride, MNC-AI hardening accelerator, frostproofer, ferrous sulfate, sal epsom and water mixing, processes light-weight brick exempt from baking under the pressure of 25-30Mpa; (3) the other utility model patent burning city domestic garbage lime-ash treatment unit (patent No.: 200920193531.1); Comprise kibbler, sifting machine, magnetic separator and supplementary unit; After incineration residue was pulverized through kibbler, the lime-ash particle was delivered to the sifting machine screening, and the bigger grey slag charge group of particle is removed in screening; Obtaining the less lime-ash fines of particle is delivered to magnetic separator and carries out magnetic separation; Remove metallic particles, e Foerderanlage is to constitute certain angle of inclination with horizontal plane, the gravity transfer pipeline that utilizes the material deadweight to transport.This utility model adopts kibbler, sifting machine and magnetic separator cooperation, can effectively remove the harmful heavy metal in the burning city domestic garbage lime-ash, can handle incineration residue in enormous quantities continuously.The technology of above incineration residue conversion product and treatment process are though have certain efficient, have certain feasibility, the cindery characteristic of optimization that can be to a certain degree.But these technical processes are not considered the physical property that cinder from refuse incineration self is complicated comprehensively; As containing characteristics such as variety, porousness, pressure-proof and snap-resistent intensity that uncombusted organic matter (containing 1.5%-3% in China's lime-ash approximately), thickness gather materials is lower in the lime-ash; If these characteristics can not be effectively addressed; The engineering characteristic of simple ash product still can not satisfy the material of construction basic demand, or life-time service still has danger such as potential damage, can't the cindery use value of optimization.In addition, in China's cinder from refuse incineration, proved coloured in metal content extremely low because the heavy metal removal technology equipment that is added in some patents, also in various degree raising the cost of lime-ash treating processes.
