生物质秸秆成型机多目标优化设计摘要：生物质压缩成型燃料可广泛用于各种类型的家庭取暖炉（包括壁炉）、小型热水锅炉、热风炉，也可用于小型发电设施，是我国充分利用秸秆等生物质资源替代煤炭的重要途径，具有良好的发展前景。目前，国内外最常见的成型机技术主要包括三大类：螺旋挤压技术、活塞冲压技术和压滚式成型技术。根据主要工艺特征，成型工艺可分为湿压成型、热压成型和炭化成型三种基本类型。本课题是针对压滚式成型技术，将原有机电传动改为机电液传动，流量控制转速，简化了机械调速系统，并能实现低转速大转矩，提高了生产效率，消除成型机被物料堵住的卡机现象，实现了设备的自动保护的功能。关键词：生物质；压缩成型；秸秆；多目标优化设计Multi-objectiveOptimizationDesignofBiomassStrawFormingMachineAbstract:Biomasscompressionmoldingfuelscanbewidelyusedinvarioustypesofhomeheatingfurnaces(includingfireplaces),smallhotwaterboilers,hotblaststovesandsmallpowergenerationfacilities.ItisthebestwaytoreplacecoalwithbiomassresourcessuchasstrawinChina.Animportantway,withgoodprospectsfordevelopment.Atpresent,themostcommonmoldingmachinetechnologyathomeandabroadmainlyincludethreecategories:screwextrusiontechnology,pistonpunchingtechnologyandpressurerollformingtechnology.Accordingtothemainprocesscharacteristics,moldingprocesscanbedividedintowetpressing,hotpressingandcarbonizationformingthreebasictypes.Thissubjectisfortheroll-formingtechnology,theoriginalmechanicalandelectricaltransmissiontomechanicalandelectricalhydraulictransmission,flowcontrolspeed,simplifyingthemechanicalspeedcontrolsystem,andcanachievelow-speedhightorque,improveproductionefficiency,eliminatingthemachinewasMaterialblockingcardmachinephenomenon,toachievetheautomaticprotectionfunctionofthedevice.Keywords:Biomass;Compressionmolding;Straw;Multiobjectiveoptimizationdesign目录第1章绪论............................................................11.1引言.............................................................11.2生物质能利用技术.................................................21.3国外生物质能开发利用概况.........................................41.3.1美国............................................................41.3.2巴西............................................................41.3.3欧洲............................................................51.3.4印度............................................................51.4我国生物质能开发利用现状.........................................5第2章生物质秸秆成型机及生物质压缩成型燃料技术..........................82.1生物质压缩成型燃料技术概念与原理.................................82.1.1生物质压缩成型燃料技术原理.....................................92.1.2生物质压缩成型燃料技术工艺....................................92.2生物质秸秆成型机概述..............................................102.2发展历史........................................................112.3固体生物质结构特点..............................................122.4生物质压缩成型原理..............................................122.5压缩成型工艺类型及阶段..........................................132.6生物质压缩成型工艺流程..........................................17第3章成型机技术.......................................................203.1螺旋挤压成型机...................................................203.2活塞压力式成型技术..............................................243.3压辊式成型机....................................................24第4章生物质...
