一种垃圾焚烧飞灰、城市污泥和钢铁冶金除尘灰冶金烧结资源化利用的方法
摘要：
一种垃圾焚烧飞灰冶金烧结资源化利用的方法，该方法包括以下步骤：(A1)飞灰预处理步骤：将垃圾焚烧飞灰和粘结剂搅拌混合均匀，得到飞灰混合料；(B1)配料步骤：将得到的飞灰混合料与其他原料混合，混合均匀，得到烧结混合料；(C)混匀制粒步骤：将初级烧结混合料通过混合机经一混、二混后得到烧结混匀料；(D)烧结步骤：将所述烧结混匀料放入烧结机台车进行烧结。本发明利用飞灰、城市污泥、钢铁冶金除尘灰中有效的化学成分用于冶金烧结，实现资源化利用。
摘要（英）：

Provided is a metallurgy sintering resource utilizing method for waste incineration fly ash. The method includes the following steps of (A1) a fly ash pretreatment step, (B1), a burdening step, (C), auniform mixing and pelletizing step and (D) a sintering step, wherein in the (A1) step, the waste incineration fly ash and a binding agent are stirred and mixed uniformly, and a fly ash mixed material is obtained; in the (B1) step, the obtained fly ash mixed material and other raw materials are mixed, and are mixed uniformly, and a sintering mixed material is obtained; in the (C) step, after theprimary sintering mixed material is subject to first mixing and second mixing through a mixer, a sintering uniformly mixed material is obtained; and in the (D) step, the sintering uniformly mixed material is placed into a sintering machine trolley for sintering. According to the method, effective chemical components in the fly ash, city sludge and steel and iron metallurgy dust removing ash are utilized for metallurgy sintering to achieve resource utilizing.
