Waste incineration fly ash granulating, solidifying and desalting method
The invention discloses a waste incineration fly ash granulating, solidifying and desalting method, according to the method, fly ash powder is solidified and clustered through a hydraulic cementing material to prepare spherical particles, the spherical particles are soaked and desalted after the fly ash powder is fully solidified, and powder raw materials in the spherical particles comprise the following components in parts by mass: 80-90 parts of red mud and 10-20 parts of the hydraulic cementing material. According to the method, the problem of desalination difficulty caused by the fact that a superfine powder material is high in water absorption and solid-liquid separation is difficult to realize during conventional water-washing fly ash desalination is fundamentally solved, the separated water washing liquid is clear and transparent and is easy to further innocent treatment and cyclic utilization, meanwhile, cement kiln co-treatment of the fly ash is realized, the problem of salt flooding of fly ash building material products is thoroughly solved, high mechanical strength is established between the granulated fly ash and a cementing material, the material can be used as lightweight aggregate to be doped into concrete, and the resource utilization approach of the fly ash is widened.
本发明公开了一种垃圾焚烧飞灰造粒固化脱盐方法，该方法通过水硬性胶凝材料将飞灰粉体固结成团制成球形颗粒，待其充分固化后将球形颗粒浸泡脱盐，所述球形颗粒中粉体原料按质量份数计包括以下组分：赤泥80~90份，水硬性胶凝材料10~20份。该方法从根源上解决了常规水洗飞灰脱盐时超细粉体材料吸水性强、难以实现固液分离而带来的脱盐困难问题，并且分理出的水洗液澄清透明，易于进一步的无害化处理及循环利用，同时实现了飞灰的水泥窑协同处置，并彻底消除飞灰建材产品的泛盐难题，经过造粒的飞灰与胶凝材料建立了较高的力学强度，能够作为轻质骨料掺入混凝土中使用，拓宽了飞灰资源化利用途径。
