摘要随着炼铁和其他相关行业的发展,焦炭的需求量也越来越大,焦化厂的建设正在突飞猛进。因此,进行炼焦车间设计具有重要的意义。首先,根据我国煤种的特点,选择了相应煤种以及配煤比,并对备煤工艺进行了初步的设计。本设计的重点是武汉某地某焦化公司拟新建一组年产量为70万吨干全焦的焦炉的工艺设计。根据实际情况,通过焦炉炉型和炭化室尺寸的选择及论证,在国家产业政策规定范围内,对炭化室孔数计算后,选取一组2×52孔4.3mJN43型焦炉。这种焦炉为双联火道、废气循环、焦炉煤气下喷、高炉煤气侧入式焦炉。同时,对焦炉的物料平衡、热量平衡、蓄热室、炉体水压以及烟囱高度进行了工艺计算;计算得出,蓄热室高度为2.16米,烟囱高度为80米;另外,合理选择了炉间台和炉端台尺寸,并对各层空间的利用进行了分布布置。对焦炉设备以及辅助设备等进行了选型;对主要的技术操作和生产控制技术进行了说明,并编制了循环推焦图表。最后,对生产的一些辅助设施进行了介绍。关键词:煤炭;炼焦;焦炉;焦炭AbstractWiththeiron-makingandotherrelativeindustriesdevelopment,thecokedemandisgrowingandthecokingplantisconstructedbyleapsandbounds.Thus,CokingWorkshopdesignisofgreatsignificance.First,accordingtothenatureofcoalinChina,thecoalblendingratiowasselectedandcoalpreparationtechnologywasalsodesigned.Thefocusofthisdesignwastodevelopawholeprocessofcokingforacokingplantwithanannualoutputof700,000tonsofdrycokeinWuhan.Basedonfeasibilitystudiesandthenationalindustrialpolicy,andaccordingtothecalculationofcokechambersize,agroupof2×52holesand4.3mcokeovenwasdevisedinthisdesign.ThisCokeOvenhasdouble-fire,theexhaustcycle,cokeovengasunderspraying,blastfurnacegasblows-intoaside.TheMaterialbalance,heatbalance,HYPERLINK"http://www.iciba.com/?s=regenerator"regenerator,hydraulicpressureandtheheightofthechimneywerecalculatedforthecokeoven.Theregeneratorheightwas2.16m,thechimneyheightwas80m.Inaddition,thesizeoftheplatformbetweenandonthetopofthefurnacewasproperlyselected,andfloorspacedistributionandusagewasarranged.TheCokeOvenequipmentsandancillaryequipmentswereselected;themaintechnicaloperationsandproductioncontroltechniquesweredescribedandcyclepushingCokechartwasdeveloped;Someancillaryproductionfacilitieswereintroducedintheend.Keywods:Coal;Coking;Cokeoven;Coke目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc170725541"1绪论PAGEREF_Toc170725541\h1HYPERLINK\l"_Toc170725542"1.1炼焦的意义PAGEREF_Toc170725542\h1HYPERLINK\l"_Toc170725543"1.2国内外炼焦技术现状和发展趋势PAGEREF_Toc170725543\h1HYPERLINK\l"_Toc170725544"1.3设计依据PAGEREF_Toc170725544\h3HYPERLINK\l"_
