毕业设计（论文） 2.4Mt/a矿井型选煤厂初步设计Mt/a矿井型选煤厂初步设计。%，是强粘结性的良好的炼焦配煤。设计任务要求精煤产品灰分小于9.0%,水分小于12%。精煤产品作为炼焦煤，中煤销售，矸石外运。 根据原煤的性质及精煤质量要求等,在进行选煤方案比较的基础上，确定出最佳的工艺流程和产品结构。即该厂为重介质选煤厂。经过工艺流程计算、设备选型等，对主厂房和总平面进行布置。同时了该厂的经济技术分析。 THE DESIGN OF 2.4 MT/A PITHED COAL PREPARETION PLANT ABSTRACT abstract: The thesis mainly states the course of primer designing on pithed coal preparation plant which produces 2.4 million tons per year. The feeding raw coal was A mixed with B by the proportion 6：4. The ash content of raw coal is 23.41%, its viscosity is strong, it is a good coal for coking manufacture .The designing task of the ash content of the clean coal no more than 9.0% and its moisture is less than 12%. According to the nature of raw coal and the quality request of clean coal, on the basis of the comparison of coal preparation plan, It confirms the optimal technological process and the structure of products. That’s to say, it is the dense medium separation plant. By the calculation of procession and the equipments selection. It arranges the main workshop and the total flat, then analysis on technology and economy. The workshop for concrete building, building capacious, daylighting rate is high. General layout fully consider terrain factors adjust measures to local conditions, high effective sound insulation, greening area of dust. This is a modernization coal preparation plant. Key words: technological, process, dense medium separation, the analysis on technology and economy, the coal preparation plant design。 目录 摘 要 I ABSTRACT II 前 言 - 1 - 第一章 设计概要 - 2 - 1.1项目背景 - 2 - 1.2 可行性研究概要 - 2 - 1.2.1 原煤资料分析 - 2 - 1.2.2选煤产品组成 - 2 - 1.2.3 选煤厂设计生产能力 - 2 - 1.2.4 选煤厂位置与交通 - 2 - 1.2.5 选煤方案的拟定 - 2 - 1.2.6 工艺流程 - 2 - 1.2.7 设备选择 - 3 - 第二章 设计前提条件及规模 - 3 - 第三章　煤源及煤制特征 - 3 - 3.1 煤源概况 - 3 - 3.1.1 原料煤供应情况 - 3 - 3.1.2 主要煤源 - 3 - 3.2 煤质特征 - 3 - 3.2.1煤的物理性质： - 3 - 3.2.2煤的化学性质 - 4 - 3.3 煤的可选性 - 5 - 3.3.1资料分析 - 5 - 3.3.2浮沉资料分析 - 5 - 3.3.3可选性分析 - 6 - 第四章 选煤工艺 - 22 - 4.1 选煤方法的确定 - 22 - 4.1.1煤的可选性 -
