Method and device for disposing waste incineration fly ash in low-energy-consumption, recycling and environment-friendly manner
The invention discloses a method and device for disposing waste incineration fly ash in a low-energy-consumption, recycling and environment-friendly manner. The method comprises the following steps that: 1) 1480-1510 DEG C blast furnace slag is added into a melting furnace, fly ash is simultaneously or subsequently added, and an obtained mixture is fully stirred, and the addition amount of the flyash accounts for not more than 25% of the total mass of the blast furnace slag and fly ash; 2) the temperature of the composite slag in the melting furnace is kept at 1400-1450 DEG C, and the reaction time is kept for 20-40 minutes under the temperature; and 3) deslagging, cooling, and water quenching treatment are carried out to obtain powdery water granulated slag, and the powdery water granulated slag is used as cement aggregate after being subjected to fine grinding.
本发明公开了一种低能耗、资源化、环保处置垃圾焚烧飞灰的方法和装置，该方法包括如下步骤：1)、将1480‑1510℃的高炉炉渣加入熔融炉，加入的同时或随后加入飞灰并充分搅拌，飞灰的配加量占高炉炉渣和飞灰总质量的比例不超过25％；2)、使熔融炉内的复合熔渣温度保持在1400‑1450℃，在此温度下保持反应时间20‑40min；3)、出渣、冷却，经水淬处理得到粉状水渣，用于细磨后作水泥骨料。
