Heat accumulator material prepared by doping industrial ceramic waste residue with sludge and preparation method of heat accumulator material
The invention discloses a heat accumulator material prepared from industrial ceramic waste residue doped sludge and a preparation method thereof, the heat accumulator material is prepared from 51-73wt% of waste roller bar of a ceramic roller kiln, 8-18wt% of alumina or nano alumina prepared from a waste alumina ceramic catalyst, 15-29wt% of water treatment plant sludge and other auxiliary materials through pretreatment and fine mixing and fine grinding of the raw materials, and the heat accumulator material is prepared from the waste roller bar of the ceramic roller kiln, the alumina or nano alumina prepared from the waste alumina ceramic catalyst, the water treatment plant sludge and other auxiliary materials. The heat storage ceramic is prepared through a series of procedures of forming and firing, the huge and urgent requirements of the current society for low-carbon, energy-saving and economical development on the heat storage ceramic can be met, and a large amount of waste is digested and utilized. Certain specific sludge, such as chromium-containing sludge and nickel-containing sludge, is taken as raw materials, and the heat storage ceramic prepared by the method has better slag resistance than common heat storage ceramic, or has auxiliary catalytic performance of oxidizing CO in waste heat flue gas to change the CO into CO2.
本发明公开了一种利用工业陶瓷废渣掺杂污泥制备的蓄热体材料及其制备方法，以陶瓷辊道窑的废辊棒51~73wt%、废氧化铝质陶瓷催化剂制备的氧化铝或纳米氧化铝8~18wt%、水处理厂污泥15~29wt%及其他辅料，通过对原料的预处理和精细混合细磨，以及成型和烧成一系列工序，制备蓄热陶瓷，不仅可满足当今社会发展低碳节能经济而对蓄热陶瓷提出的的庞大、急迫的需求，也消化利用了大量废物。以某些特定的污泥，如含铬污泥、含镍污泥为原料，用本方法制备的蓄热陶瓷，有比普通蓄热陶瓷更好的抗渣性能，或具有氧化余热烟气里的CO使之变成CO2的辅助催化性能。
