In-situ resource utilization method of waste incineration ash and fly ash
The invention belongs to the technical field of waste resource utilization, and particularly relates to an in-situ resource utilization method of waste incineration ash and fly ash. The method is characterized in that waste ash, fly ash, tuff and ash lava are used as main raw materials, thermal activation is performed on the gelling characteristics of the tuff and the ash lava by virtue of a waste incinerator, a small amount of quick lime, sodium hydroxide and/or water glass and desulfurized gypsum are supplemented, and a cheap hydraulic novel environment-friendly cementing material is formed through reasonable proportioning, replaces the curing effect of cement in the building material industry and is used for producing building blocks for building materials. The volcano tuff and the coagulated lava which are widely distributed in China and are low in price are used as admixtures of household garbage to be incinerated together to generate powder with high-strength gelling activity, the powder is mixed with other powder to form a set of complete technical system integrating configuration and workpiece manufacturing, and the produced building block has low cost, low carbon emission, and good physical properties, and meets the requirements of energy conservation, emission reduction and green sustainable development.
本发明属于废物资源化利用技术领域，具体涉及一种垃圾焚烧灰渣及飞灰的原位资源化利用方法，以废弃灰渣、飞灰和凝灰岩、凝灰熔岩为主要原材料，借助垃圾焚烧炉对凝灰岩、凝灰熔岩的胶凝特性进行热力活化，再辅以少量的生石灰、氢氧化钠和/或水玻璃、脱硫石膏，通过合理配比形成廉价的水硬性新型环保胶凝材料，取代建材行业中“水泥”的固化作用，用于生产建材用砌块。本发明选用我国分布广泛，价格低廉的火山凝灰岩、凝灰熔岩作为生活垃圾的掺合料一起焚烧，生成高强胶凝活性的粉料，并与其它粉料混合，形成一套集配置、制件为一体的完整技术体系，生产出的建材砌块具有低成本，低碳排放，良好的物理性能，符合节能减排、绿色可持续发展的要求。
