Composite phase change heat storage ceramsite prepared from waste incineration fly ash and ferronickel slag and preparation method of composite phase change heat storage ceramsite
The invention discloses composite phase change heat storage ceramsite prepared from waste incineration fly ash and ferronickel slag and a preparation method of the composite phase change heat storage ceramsite. The waste incineration fly ash, the ferronickel slag and the phase change material are prepared into double-layer composite pellets, and the pellets are dried, roasted and cooled to obtain the phase change heat storage ceramsite. The inner layer of the pellet is controlled to be the mixture of the waste incineration fly ash, the ferronickel slag and the phase-change material, the outer layer of the pellet is controlled to be the mixture of the waste incineration fly ash and the ferronickel slag, it can be guaranteed that the interior of the ceramsite is porous, the surface of the ceramsite is a compact glaze layer, and good encapsulation of the phase-change material is achieved. The obtained phase change heat storage ceramsite product has the characteristics of light weight, high strength, good stability and the like, and the synergistic high-value utilization of the waste incineration fly ash and the ferronickel slag is realized.
本发明公开了一种利用垃圾焚烧飞灰与镍铁渣制备得到的复合相变储热陶粒及其制备方法。本发明将垃圾焚烧飞灰、镍铁渣与相变材料制成双层复合球团，球团经干燥、焙烧、冷却处理，即可得到相变储热陶粒。本发明通过控制球团内层为垃圾焚烧飞灰、镍铁渣与相变材料混合料，外层为垃圾焚烧飞灰与镍铁渣混合料，可保证陶粒内部多孔，表面呈致密釉层，实现对相变材料的良好包封。所得相变储热陶粒产品具有轻质、高强、稳定性好等特性，实现了垃圾焚烧飞灰与镍铁渣的协同高值化利用。
