摘要本设计为年产1000t复合型阻燃剂三(三溴苯基)磷酸酯的生产工艺的初步设计。根据最新实验研究结果,设计出新型生产工艺流程,用二甲苯做溶剂以路易斯酸作催化剂,使三溴苯酚和三氯氧磷在140℃下反应。反应时,三氯氧磷与三溴苯酚生先成一酯、二酯。随反应进行,反应的空间位阻变大,生成三酯需要较长的反应时间。因此设计中采用六个间歇反应釜、两个水洗反应釜和一个盐酸吸收塔,生产开车时,反应釜时间隔4小时加料,反应产物间隔8小时分批水洗蒸馏,盐酸集中到一个盐酸吸收塔处理。在保证产量的同时,同样保证生产的连续性和稳定性。本设计通过物料衡算和能量衡算,对主要反应设备、分离和换热设备进行了设备选型设计。同时根据工艺流程的选择,对车间设备布置,工厂建筑物的布置等进行了初步设计。关键词:三氯氧磷;三(三溴苯基)磷酸酯;复合阻燃剂;工艺设计ABSTRACTThedesignforthepreliminarydesignoftheannualoutputof1000tcompoundflameretardanttris(bromophenyl)phosphatefactory,plansyieldof3.33t/day.Thechoiceofthedesignprocess,workshopequipmentlayout,thelayoutofthefactorybuilding,thepreliminarydesignoftheequipmentselectionhavebeendesigned.Undertheexperimentalconditions,thedesign,designedanewproductiontechnology.Inzhedesign,Xyleneacidassolvent,Lewisacidascatalyst,thereactionoftribromophenolandphosphorusoxychlorideat140.Firstly,thephosphorus℃oxychloridetribromophenolbornintoanester,diester..Withthereaction,thereactionstericbecomelarger.Generatingthreeestersrequirealongerreactiontime.SoIdesignedsixbatchreactor,twowashingreactionvesselandahydrochloricacidabsorber.Reactoriseveryfourhoursfeeded,thereactionproductofanintervalof8hourswashingbatchdistillation,hydrochloricacidisconcentratedtoahydrochloricacidabsorberprocessing.Itguaranteethecontinuityandstabilityofproductiontoensurethatproductionatthesametime.Itistheinnovationpointofthedesignpoint.Inthedesign,productionprocessshowedaU-shapeddistribution,Theworkshoplengthandwidthare12m.Sixsetsoftwostandardenamelresponseequipmentarelayouted.Productpackagingworkshopandcoolingsetupshopindependently.Asignificantreductioninleakagecausedbydustpollutionandcoolingprocess,theheatgeneratedinterferenceduetothree(3-bromophenyl)phosphatepowder.Thefactoryis70mlong,43mwide.Thebuildingarea860,buildingcoefficientwas0.278,greenareaof788m2,greeningratewas26.18%.Thebuildingareais860m2,buildingcoefficientis0.278,greenareais788m2,greeningrateis26.18%.Keywords:Phosphorusoxychloride;Tribromophenol;Compositeflameretardant;Processdesign目录第一章概述…………………………………………………………1第一节阻燃剂概述…………………………………………………1第二节选题的目的及意义…………………………………………2第二章工艺技术设计………………………………………………5第一节实验确定反应条件…………………………………………5第二节反应工艺设计………………………………………………7第三章设备选型计算………………………………………………9第一节反应物料衡算………………………………………………9第二节反应釜设计…………………………………………………9第三节加料装置设计………………………………………………11第四节水洗反应釜…………………………………………………12第五节盐酸吸收塔设计……………………………………………13第六节冷凝器设计…………………………………………………20第四章车间和厂区布置……………………………………………29第一节车间布置……………………………………………………29第二节厂区布置……………………………………………………29结论……………………………………………………………………31参考文献………………………………………………...
