3.0_Mt选煤厂工艺设计说明书.pdfVIP

摘 要 本设计为唐山赵各庄矿井型 3.0 Mt/a 选煤厂工艺设计，赵各庄是隶属于 开滦集团的矿井型选煤厂。首先根据生产大样和浮沉试验资料，绘制可选性 曲线；可选性曲线绘制完成后确定原煤为难选煤，因此采用重介-浮选联合流 程的选煤方法，制定了工艺流程；然后进行工艺流程计算，编制最终产品平 衡表；最后进行选煤厂工艺布置和经济概算。该设计具有流程简单、结构合 理，投资低（14989.493 万元），投资回收期短（0.187 年），生产效率高等特 点。因此，本设计较为适用。 专题论文主要介绍了浮选柱的结构、原理、类型、特点及浮选柱在国内 外煤炭行业中的应用，主要应用于细粒煤的脱泥降灰。浮选柱具有广阔的应 用前景，不仅仅在煤炭方面，在其它金属矿的提纯方面也有广泛的应用。 关键字：难选煤 经济效益 选煤方法 工艺流程 I Abstrack The design for the Tangshan Mine Type 3.0 Mt / a coal preparation plant design. First of all, producing samples and drifting under the experimental data, curve drawing options; optional Curve coal after the completion of difficult preparation, so by HM - Coal flotation method of the joint process to develop a process; then calculation process, the preparation of the final product balance; Finally, Coal Preparation Plant layout and economic estimates. The design is simple, reasonable structure, low investment (149,894,930 yuan), the investment recovery period is short (0.187year), the production of high efficiency. Thus, the more successful design. Monograph introduces the flotation column describes the structure, principles, types, characteristics and flotation column in the application of domestic coal industry, mainly used in fine coal ash falling off mud. Flotation column has a wide application prospect, not only in the coal side, the purification of other metal mining also has a wide range of applications. Keyword: difficult separating coal, economy benefit, coal preparation methods, craft. II 目录 摘 要 I Abstract II 第 1 章 绪论 1 1.1 选题意义 1 1.2 厂区概况 1
