河南机电高等专科学校毕业设计论文论文题目:六氟磷酸锂的生产工艺及含氟废气废水的治理系部:电气工程系专业:应用化工技术班级:2009级01班学生姓名:学号:指导教师:2012年5月9日摘要随着电动自行车的普及和新能源汽车的推广,锂离子电池的生产规模将会出现较大幅度增长在锂离子电池电解质锂盐六氟磷酸锂工业化生产过程中,必然伴随有一定量的含氟废气和废水外排。因此,做好含氟废气和废水的检测、治理工作也同样是工厂顺利生产的必要条件。该论文在介绍六氟磷酸锂制备方法基础上,阐明了六氟磷酸锂工厂的生产安全和防护措施,提出了氟废气和含氟废水相应的治理方法,氟废气主要以氟化氢为主,因为氟化氢和水的有很高的亲和力,所以常用水吸收的方法除去氟化氢气体,最好的方法是将其转化成氟盐;对于含氟废水的治理,以石灰—粉煤灰联合工艺为最好的处理方法。关键词:六氟磷酸锂;制造工艺;治理ABSTRACTWiththepopularityofelectricbicycleandthepromotionofthenewenergyvehicles,lithiumionbatteryproductionscalewillappearmoreincreasesubstantially.Inthelithiumionbatteryelectrolytelithiumfluoridelithiumphosphatesixindustrialproductionprocess,theinevitablewithacertainamountofcontainingfluorinewastegasesandwaterdischarge.Therefore,completescontainingfluorinewastegasesandwatertestingandtreatmentworkisalsothenecessaryconditionsforthesmoothproductionfactory.Thepaperexpoundssixfluorinephosphoricacidlithiumfactoryproductionsafetyandprotectivemeasures,andputforwardthefluorinewastegasandcontainingfluorinewastewatercorrespondingtreatmentmethod,fluorinewastegasmainlycurrentlyisgivenpriorityto,becausethewaterisveryhighandcurrentlytheaffinity,socommonlyusedthemethodofwaterabsorptionremovecurrentlygas,bestImethodistotranslateintofluoridesalt;Forcontainingfluorinewastewatertreatment,withflyashlime-jointprocessforthebestwaytohandle.KeyWords:Lithiumhexafluorophosphate;manufacturingengineering;managementII目录摘要.......................................................................................................................I绪论.......................................................................................................................1第1章概述..............................................................................................21.1六氟磷酸锂的性状及用途.................................................21.2国内外六氟磷酸锂发展现状..........................................2第2章六氟磷酸锂制造工艺及其控制.................52.1传统的制备方法.............................................................................52.2国外早期制备工艺......................................................................62.3近期制备工艺....................................................................................7第3章含氟废气、废水的治理...................................123.1六氟磷酸锂工厂的生产安全与防护.................123.2六氟磷酸锂工厂含氟废气的治理........................133.3含氟废水的治理.........................................................................15第4章展望...........................................................................................19致谢...................................................................................................................22参考文献.....................................................................................................23III河南机电高等专科学校毕业设计/论文绪论随着科技的不断发展和新能源的不断推广,锂电作为新能源其中之一具有非常大的潜力,它将在在新能源的发展中崭露头...
