Cooperative polluted soil treatment system for cement kiln
The invention discloses a cement kiln cooperative polluted soil treatment system which comprises a material preparation stage, a treatment stage and an ending stage, and in the material preparation stage, to-be-treated waste fuel and polluted soil are prepared according to a set proportion; in the treatment stage, waste fuel and polluted soil are subjected to pretreatment and rotary kiln incineration treatment; in the ending stage, a product obtained after incineration in the rotary kiln is mixed with clinker for cement production, and the mixture is added into the cement kiln to be fired into finished cement, the method is suitable for cement production, in the pretreatment stage of the polluted soil, large-hardness objects in the polluted soil are removed, then the polluted soil is dried, and the finished cement is obtained. And meanwhile, the drying temperature is controlled to be 250 DEG C or below, so that toxic substances in the polluted soil can be prevented from reacting and releasing due to the fact that the temperature is too high.
本发明公开了一种水泥窑协同用污染土处理系统,包括备料准备阶段、处理阶段和收尾阶段,备料准备阶段是按照设定的比例预备待处理的废物燃料和污染土;处理阶段是对废物燃料和污染土进行预处理和回转窑焚烧处理;收尾阶段是将回转窑焚烧后的产物与水泥生产用熟料进行混合并加入到水泥窑中烧制成成品水泥,本发明适用于水泥生产,本发明在对污染土的预处理阶段中,通过去除污染土中的大硬度物体,再对其进行烘干,这样可以方便污染土的后期加工,同时将烘干温度控制在250℃以下,这样可以避免温度过高引起污染土中有毒物质反应释放。
