《180万吨大型选煤厂设计说明书》-毕业论文.doc

w 摘要 本次设计为180万吨大型选煤厂。入洗的原煤为呼和乌素煤矿的原煤及周边煤矿的高灰煤。原煤属于易选煤，为了大量分选出精煤，提高其利用率，经过对煤质的分析及经济对比和可行性研究，最后确定采用重介质分选。另外，在设计过程中本着节约成本、提高生产效率、优化厂房设计等思想，主要以呼和乌素煤矿的原煤资料作为设计的依据，介绍重介质选煤工艺流程，及设备的选用。 关键词： 选煤厂 设备选型 可选性 Abstract This design for 180 tons of large coal. Into the wash of coal mine WuSu for shout and crude and surrounding the high grey coal mine. Coal belong to easy to large coal cleaning plant, improve its disadvantage that, through the utilization of coal quality comparison and analysis and economic feasibility study, the final determination by heavy medium separation. In addition, in the design process in line with reduce cost, improve production efficiency, optimizing plant design thought, mainly shout and WuSu coal mine coal material as the design basis of heavy medium, introduces coal cleaning process, and the selection of equipment Keywords: Election coal Plant equipment selection optional 目录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc294542360 摘要 PAGEREF _Toc294542360 \h 1 HYPERLINK \l _Toc294542361 Abstract PAGEREF _Toc294542361 \h 2 HYPERLINK \l _Toc294542362 目录 PAGEREF _Toc294542362 \h 3 HYPERLINK \l _Toc294542363 前言 PAGEREF _Toc294542363 \h 4 HYPERLINK \l _Toc294542364 第一章 矿区及原料煤基地概况 PAGEREF _Toc294542364 \h 5 HYPERLINK \l _Toc294542365 （一）矿区概况 PAGEREF _Toc294542365 \h 5 HYPERLINK \l _Toc294542366 （二）原料煤特征 PAGEREF _Toc294542366 \h 6 HYPERLINK \l _Toc294542367 第二章 原煤特征及可选性 PAGEREF _Toc294542367 \h 11 HYPERLINK \l _Toc294542368 （一）煤质特征 PAGEREF _Toc294542368 \h 11 HYPERLINK \l _Toc294542369 （二）工艺性能 PAGEREF _Toc294542369 \h 12 HYPERLINK \l _Toc294542370 （三）原煤可选性 PAGEREF _Toc294542370 \h 14 HYPERLINK \l _Toc294542371 第三章 选煤产品用途及产品方案 PAGEREF _Toc294542371 \h 31 HYPERLINK \l _Toc294542372 （一）产品方案 PAGEREF _Toc294542372 \h 31 HYPERLINK \l _Toc294542373 （二）选后产品的用途、用户 PAGEREF _Toc294542373 \h 31 HYPERLINK \l _Toc294542374 第四章 选煤工艺 PAGEREF _Toc294542374 \h 31 HYPERLINK \l _Toc294542375 （一）数、质量计算 PAGEREF _Toc294542375 \h 31 HYPE
