Resource utilization method of electrolytic manganese press filter residues
The invention discloses a resource utilization method of electrolytic manganese filter-press residues, which relates to the field of metal smelting waste treatment, and comprises the following steps: step 1, carrying out on-machine washing on the electrolytic manganese filter-press residues through washing type filter-press equipment to reduce the residues of pollutants in the residues, according to the method, the electrolytic manganese press filter residues are washed and dried into the granular powder, so that the granular powder can better participate in the reaction and mixing subsequently, and the material powder is dried by the dryer to avoid the situation that the subsequent desulfurization reaction is influenced by residual moisture in the material powder; the material powder is thermally decomposed through the reducing atmosphere and boiler equipment, so that sulfate and other sulfides in the material powder are separated and separated out to generate sulfur dioxide, the electrolytic manganese press filter residues are conveniently recycled, the sulfur content in the electrolytic manganese press filter residues is effectively reduced, and therefore the produced building materials are prevented from being influenced.
本发明公开了一种电解锰压滤渣的资源化利用方法，涉及金属冶炼废渣处理领域，包括如下步骤：步骤一，通过洗涤型压滤设备将电解锰压滤渣进行在机洗涤，减少渣中污染物的残留，之后通过粉末烘干设备内烘干减少水分制成颗粒状物料粉末，本发明通过将电解锰压滤渣进行洗涤并烘干成颗粒状粉末使其后续可以更好参与反应和混合，通过烘干机将物料粉末烘干避免其内部残留有水分影响后续脱硫反应，通过还原气氛与锅炉设备将物料粉末热分解使其内部的硫酸盐和其他硫化物分离析出产生二氧化硫，方便将电解锰压滤渣回收再利用，有效减少电解锰压滤渣内的硫含量从而避免产出的建筑材料受到影响。
