Method for producing concrete additive through resource utilization of electrolytic manganese residues
The invention relates to a method for producing a high-performance concrete additive by resource utilization of electrolytic manganese residues, which comprises the following steps: adding a certain amount of pollution-free water or electrolytic manganese catholyte into the electrolytic manganese residues for washing, then carrying out primary separation by adopting gravity standing precipitation, further separating the precipitate by using a centrifugal machine or a filter press to obtain a wet product containing residual water, and directly utilizing the wet product; respectively metering and washing the electrolytic manganese residues and a dispersing agent according to a ratio, putting the electrolytic manganese residues and the dispersing agent into an intelligent disperser for fully dispersing and mixing, and entering a curing process after meeting requirements; respectively and intelligently metering the mixed material and a curing agent according to a certain proportion, putting the mixed material and the curing agent into a special curing reactor, implementing a curing process, effectively curing harmful components such as inorganic salts and heavy metal ions, converting ammonia nitrogen in the material into ammonia gas, fully releasing the ammonia gas, and recycling the released ammonia gas; and screening, detecting and packaging the cured material to obtain a commercial concrete additive, and returning the screened and detected non-standard part of the material to the dispersion process and/or the curing process for continuous application.
一种电解锰渣资源化利用生产高性能混凝土助剂方法，电解锰渣加入一定量的无污染水或电解锰阴极液洗涤后采用重力静置沉淀初步分离，沉淀物用离心机或压滤机进一步分离得到的含残留水份的湿品直接利用；按比例分别计量洗涤电解锰渣和分散剂投运到智能分散器中充分分散混合，达到要求后的进入熟化工序；按一定比例要求将混合物料和熟化剂分别智能计量投入专用熟化反应器实施熟化过程，将各无机盐、重金属离子等有害成分得到有效固化，同时物料中的氨氮转化为氨气得到充分释放，释放出来的氨气回收利用；熟化完成后的物料通过分筛、检测、包装得到商品混凝土添加剂，分筛、检测不合规格部分物料返回分散工序和/或熟化工序持续套用。
