400kA预焙槽铝电解车间设计本科毕业设计(1)VIP免费

400kA预焙槽铝电解车间设计摘要大型化是当今世界铝电解技术发展的大趋势。在现有的320kA~350kA大型铝电解槽基础上，进一步开发并建设高效、稳定和更为节能的400kA大型铝电解槽技术是当今世界各大铝业公司研究和追求的目标。并且我国已经有多家铝电解企业已经建成400kA级铝电解生产线。我们紧随时代步伐，设计了400kA预焙槽铝电解车间。车间设计包括厂址选择、电解槽设计、电压平衡、能量平衡劳动定员及成本核算等。该设计的年产量为22万吨，电流效率高达94%。经过多方论证厂址选择伊川县工业园区。关键词：铝电解槽，物料平衡，能量平衡，电压平衡，车间设计TheDesignof400kAPre-bakedAnodeAluminumReductionPlantABSTRACTLarge-scaleisthegeneraltrendofaluminiumelectrolysistechnologicaldevelopmentintheworldnowadays．Developingmoreefficient，morestableandmoreenergy-saving400kAaluminiumreductioncelltechnology，basedontheexisting320kA~350kAaluminiumreductioncell，isthegoalstudiedandchasedbyworldwidemajoraluminiumcompanies．Andthereareafewaluminumelectrolysisenterprisesthathavebuilt400kAgradealuminumelectrolyticproductionline．Followingthepaceoftimes，wecompletethedesignofthe400kApre-bakedaluminumelectrolysisworkshop．Thedesignsincludesite-selection，designsofelectrolyzers，voltagebalance,energybalance，laborquotaandcostaccountingandsoon．Yieldofthedesignreachestotheannualoutputof220000tons，andthecurrentefficiencyashighas94%．Aftermanydiscussions，wedecidetochooseYichuanCountyIndustrialParkasthesite．KEYWORDS：aluminumreductioncell，materialbalance，energybalance，voltagebalance，thedesignofworkshop目录前言..................................................................................................1第一章铝电解简介...........................................................3§1.1铝的性质及用途..................................................3§1.1.1铝的性质...........................................................3§1.1.2铝的用途...........................................................3§1.2铝电解简史及发展现状..............................4§1.2.1铝电解简史.....................................................4§1.2.2我国铝电解技术发展现状..............6§1.2.3世界铝电解工业技术现状..............7§1.3铝电解用原料与原材料..............................9§1.3.1铝电解原料——氧化铝....................9§1.3.2铝电解熔剂——氟化盐.................10§1.3.3铝电解预焙阳极炭块........................11§1.4铝电解过程描述..............................................12§1.5铝电解槽与电解槽系列...........................13§1.5.1阴极装置........................................................13§1.5.2阳极装置........................................................13§1.5.3母线装置........................................................14§1.5.4使用寿命........................................................15第二章厂址选择与论证...........................................16§2.1.电力供应..................................................................16§2.2.运输系统..................................................................16§2.3.外围服务..................................................................17§2.4.环境和土地...........................................................17第三章技术经济...............................................................18§3.1主要技术经济指标的选择论证.......18§3.2综合经济技术指标的计算....................19§3.3主要经济技术指标的确定与列表.21第四章物料平衡...........................
