Description

Combined disposal and utilization system for various solid wastes
Technical Field
The utility model relates to the technical fields of environmental protection, energy, chemical industry and the like, in particular to a system for jointly treating and utilizing various solid wastes.
Background
The solid wastes are various in types, such as domestic wastes, biomass, general industrial solid wastes, hazardous wastes, construction wastes, polluted soil and the like. According to different classification standards, common industrial solid wastes can be further subdivided, and according to the environmental protection statistical standard, the industrial solid wastes can be divided into 10 types such as smelting waste residues, tailings, sludge, red mud, phosphogypsum, desulfurized gypsum, fly ash and the like.
Among various solid wastes, the processes of domestic waste incineration, biomass blending combustion and the like are relatively mature, and have been industrially applied for many years in China. The disposal of general industrial solid waste, hazardous waste, construction waste and polluted soil is laggard, the general industrial solid waste and construction waste are mainly stockpiled and buried at present, and the hazardous waste and polluted soil are mainly mixed and burnt in a cement kiln. Along with the continuous promotion of the urbanization process of China, the yields of construction waste and industrial solid waste are increased year by year, and along with the migration of a large amount of urban area industries, the total amount of the disposal of the polluted soil is also continuously increased. Meanwhile, the environmental standard of China is promoted year by year, related laws and regulations are continuously sound, and the harmless disposal and resource utilization of the solid wastes are gradually paid attention.
The common industrial solid wastes, construction wastes and polluted soil also have relatively feasible treatment and disposal technologies, but all have the defects of insufficient harmony and high single disposal cost. For example, steel slag, smelting waste slag and the like in common industrial solid waste can be ground and mixed into a cement kiln for calcination, but the mixing amount is less and the disposal capability is limited; municipal sludge can be dried and then co-burned or independently burned, but due to the characteristic of high water content (generally, the water content of the municipal sludge after leaving a factory is as high as 80%), a large amount of biomass or natural gas is required to be added as auxiliary fuel during burning; the construction waste contains a large amount of light substances (such as wood, package, fabric and the like) besides concrete components, the sorted concrete blocks can be crushed for secondary utilization, but the light substances are still difficult to dispose and are mostly sent to other incineration plants for paid incineration, and the cost is higher; the polluted soil contains partial heavy metals, the heavy metals can be solidified by firing the building materials at high temperature, but the polluted soil can not form building materials such as ceramsite, ceramic and the like after being independently calcined, and the polluted soil needs to be calcined together with substances such as steel slag, fly ash and the like in proportion.
In conclusion, the single technology for treating the solid wastes such as general industrial solid wastes, construction wastes and polluted soil has great limitation, and the problems of high treatment cost, insufficient resource utilization and the like are finally caused due to the defects of more material balance and energy balance. The research and development of the cooperative treatment technology and process of various solid wastes fully utilizes the cooperative effect of each component in various solid wastes, and the formation of the multi-type, low-energy-consumption and high-efficiency combined treatment process technology becomes urgent.
