Description
Technical Field
The invention belongs to the field of foaming expansion experiments, and particularly relates to a foaming expansion test device for municipal refuse incineration bottom ash under alkali.
Background
With the rapid development of social economy and the continuous acceleration of urbanization process, the waste generated in the production and living processes is increased, wherein the annual output of municipal solid waste is increased continuously in recent years, so that a series of hazards are caused, and the life of people is seriously influenced.
At present, the reduction and harmless treatment of municipal solid waste are mainly incineration and landfill. Municipal Solid Waste Incineration (MSWI) products are mainly divided into two categories: one type is fly ash, accounting for about 20% of the total. The other is bottom ash, which accounts for about 80% of the total amount. Bottom ash is usually collected at the bottom of a combustion boiler and is composed of different types of large particles (<45mm) including molten slag, glass, stone, small metal chips, etc. The bottom ash is composed mainly of elements with high boiling points, e.g. Si4+、A13+And so on, the bottom ash belongs to solid waste which can be directly recycled.
The accumulation of MSWI bottom ash also causes pollution to the atmospheric environment and water resources, and becomes breeding places of a large number of pathogenic microorganisms and pests, and has huge potential hazards. Moreover, the landfill treatment of the MSWI bottom ash wastes a large amount of manpower and material resources and causes serious pollution to the underground environment. The landfill treatment of the MSWI bottom ash is unscientific and uneconomical. Therefore, the multi-channel, large-scale safe digestion and resource recycling of the MSWI bottom ash are urgent.
The alkali-activated material is an inorganic non-metallic material newly developed in recent years, mainly uses natural aluminosilicate minerals or industrial solid wastes as main raw materials, is fully mixed with other mineral admixtures and a proper amount of alkali silicate solution, is cured and formed under the condition of normal temperature or steam pressure, and is a gelled material bonded by aluminosilicate gelled components. Compared with portland cement, the alkali-activated material has the advantages of high strength, high temperature resistance, acid and alkali corrosion resistance, low permeability and the like; in the production process, high-temperature calcination or sintering is not needed, and the polymerization reaction can be completed at normal temperature. Therefore, the alkali-activated cementing material prepared by using the bottom ash as the raw material can realize the resource utilization of the bottom ash and change waste into valuable, and the alkali-activated cementing material can completely replace cement as a novel building material, thereby having important significance for countries with energy shortage and serious environmental pollution.
At present, the bottom ash can generate serious foaming expansion phenomenon when meeting a strong alkaline environment, so that a bottom ash cementing material generates expansion deformation, the mechanical property of the material is suddenly reduced, and the bottom ash cementing material cannot be applied to engineering practice. Therefore, in order to finally prepare the bottom ash alkali-activated cementing material with high strength, good application property and durability, repeated experiments are needed, and most basically, the foaming expansion phenomenon is eliminated.
Present experimentation is artifical with municipal refuse incineration bottom ash and drops into the alkali and react in, but the manual operation experiment is difficult to regulate and control multiple variable, and the bottom ash drops into the alkali back needs intensive mixing even, this just makes needs the manual work to stir, but make the alkali splash to the experimenter and cause the damage on one's body easily after the foaming inflation in the reaction process, consequently design one kind can control the experimental variable, and replace the experimenter to carry out the device that the foaming inflation was tested and be accorded with actual need.
