Abstract
The invention discloses comprehensive utilization of construction waste. The comprehensive utilization is realized by the following steps: firstly, appropriately crushing the construction waste, selecting out metal, plastic and glass in the construction waste in a manual and/or mechanical mode, subsequently pouring the rest materials into a combustion furnace to be combusted, and applying the obtained heat energy to a generator for power generation; screening dust slag after combustion so as to separate a power material and stone grains; adding a curing agent into the obtained powder material, and performing ordinary treatment so as to prepare the material into cement; screening the obtained stone grains in a washing mode, and subsequently placing in different classes; feeding the metal waste which is obtained through separation into a furnace so as to be prepared into steel materials of different models; recycling and machining the plastic and glass waste obtained through separation into recycled glass or decorative materials. Therefore, the construction waste can be sufficiently and effectively utilized, and the pollution of the construction waste to the environment is reduced.
Description
Technical field
The present invention relates to a kind of building waste recoverying and utilizing method, be specifically related to a kind of comprehensive utilization of building waste.
Background technology
Along with the quickening of urban construction paces, large quantities of old buildingss are removed, and building waste also increases gradually.In recent years, the unified perfect treating construction waste method of China, building waste is taked directly to abandon or the simple process such as landfill mostly.So these rubbish not only take a large amount of soils and place, building coating in building waste, paint, plastics etc. are the macromolecule polymeric material of hard degradation, and contain harmful heavy metal element can spoiled soil structure, cause ground settlement, but also serious contaminate environment, directly harm periphery resident's daily life, brings hidden danger.So the integrated conduct method of developing a kind of building waste is the key addressing the above problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of comprehensive utilization of building waste, can fully effectively improve the comprehensive utilization ratio of building waste, reduces the pollution of building waste to environment.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
The comprehensive utilization of building waste, is characterized in that, comprises the following steps:
1) first by after the suitable fragmentation of building waste, through artificial and/or mechanical system, metal species wherein, Plastic, glass sorting are picked, then surplus material to be poured into incinerator and burned, the heat energy obtaining generates electricity for generator;
2) the dirt slag after burning sieves, and isolates powder and stone particle;
3) in the powder obtaining, add some solidifying agent, after conventional processing, make cement;
4) at the stone particle obtaining, through rinsing the laggard row of screening, sort out placement;
5), after the metal species waste obtaining through sorting melts down again, manufacture the steel of all size;
6) Plastic obtaining through sorting, glass waste reclaim and are processed into repeat glass or decoration bar section.
Such scheme, the weight percent of described each component of cement is: powder 70～90%, solidifying agent 10～30%.
Beneficial effect of the present invention is: production technique of the present invention is simple, and by processing that building waste is classified, reprocessing can obtain different products, makes building waste obtain fully effectively again utilizing, and reduces the pollution of building waste to environment.
