Description
Technical Field
The application relates to the technical field of garbage treatment, in particular to a slag treatment system.
Background
With the development of society, industry and economy, the problem of controlling environmental pollution of municipal solid waste has become an important issue for environmental protection in the world, and the treatment of municipal solid waste requires harmless treatment and recycling of solid waste.
The three-transformation principle of solid waste pollution prevention and control, namely reduction, recycling and harmlessness of solid waste pollution prevention and control, is legally established in the environmental protection and control law of solid waste pollution of the people's republic of China, which is carried out from 4.1.1996, and is used as a basic technical policy of solid waste management in China and points a direction for municipal domestic waste treatment.
The existing municipal solid waste treatment mainly reduces the storage amount of municipal solid waste through the modes of centralized stacking and landfill of the waste, incineration of the waste and the like, but the treatment modes have various determinations of large air pollution, wide occupied area, long waste treatment time, complex waste treatment and the like.
The garbage is used for garbage incineration power generation, and is a more advanced treatment mode with relatively less environmental pollution compared with garbage treatment, but the slag treatment after combustion almost adopts a landfill mode. The quantity of garbage burned in a garbage burning power plant in the Longwan area is 2500 tons per day, and 800 tons of 'unburnt' slag is generated, so that the quantity of the slag buried in the Longwan area is about 30 ten thousand tons (only in the Longwan area) in the year by calculation, and a large amount of land resources are also occupied.
In addition, the garbage is incinerated at a high temperature of 1000 ℃ to form slag by utilizing the garbage power generation technology. The granules have different sizes and complex components, and the main components are Ca, Si, Na, K, Ke, Al and partial heavy metals. Although the furnace slag is sintered, a large amount of early-stage impurities such as stones, cement blocks, glass, iron sheets and bottle caps, and iron and copper metals such as iron nails, iron wires, iron sheets, copper nuts and the like are mixed in the process of leaving the factory. The substances are buried, and potential safety hazards are brought to soil and underground water. The heavy metal substances in the household garbage incineration slag are metal materials, and ash powder, stones and other components mainly comprise calcium carbonate, silicate and the like, namely the base materials for the building materials such as cement and the like. Therefore, it is necessary to perform a harmless, recycling and reduction treatment. The best processing method is to sort and screen the furnace slag, sell heavy metal substances, make the remaining ash powder, stones and the like into environment-friendly sand to be supplied to building material manufacturers to produce building materials, realize industrialization and convert the environment-friendly sand into enterprise profits.
In conclusion, a set of complete system engineering is used for processing slag metal screening, slag ash and the like, waste of resources such as land and the like can be reduced, waste is turned into wealth, and the defect of pure slag landfill processing is effectively overcome. However, the slag treatment production line in the prior art is easy to have the problems of incomplete metal screening, time consumption, labor consumption and the like.

The separated water enters a circulating pool 23 after being subjected to sedimentation treatment in a sedimentation pool 22, and then is recycled by the sorting equipment through a circulating pump 24. Meanwhile, waste gas generated in the process enters a protective cover arranged on the complete equipment to be collected in a centralized manner, is subjected to harmless filtration treatment and is discharged.
After the slag is separated and screened, heavy metal substances in the slag are recycled, and the remaining unburnt garbage in the slag is separated and collected, so that the slag can be used in a garbage incineration power plant 1 for returning to a furnace for power generation, and the resource utilization ways of the remaining slag (environment-friendly sand) mainly comprise: the petroleum asphalt pavement replaces aggregate; substitute aggregate of cement concrete; filling materials for embankments, roadbeds and the like, and manufacturing environment-friendly bricks and the like.
In order to achieve an ideal screening effect, a suspended magnetic separator is adopted in the magnetic separator selection, and multi-stage rollers, magnetic separation, crushing, jigging and water separation mixed weaving are adopted. And a protective cover or a dust absorption and odor absorption device is added above each process, harmful gas generated by the waste incineration slag in the screening process is collected, filtered and discharged after reaching the standard, the air pollution is reduced, and the air quality of a workshop of staff is ensured.
