毕业 课题名称： 摘 要 本设计是年产10万吨聚氯乙烯（PVC）聚合工段初步设计。本文对聚氯乙烯的研究，生产和应用进行了详细的述，确定了聚氯乙烯的生产工艺。采用了悬浮聚合工艺，后处理工段采用了无溢流汽提装置和先进的旋流干燥装置。在上述工艺的基础上，以SG-5型号PVC树脂为例进行了物料衡算，热量衡算，设备选型等。 关键词：聚氯乙烯（PVC） 氯乙烯 物料衡算 热量衡算 聚合反应 Abstract This design is to produce 100,000 tons of polyvinyl chloride ( PVC ) polymerization workshop section in the preliminary design .In this paper a detailed overview of the research , production and application of PVC to determine the PVC production process . Using a suspension polymerization process , post-processing section in the no overflow stripping unit and advanced cyclone drying plant . On the basis of the above-mentioned process , the SG -5 type PVC resin as an example material balance , heat balance , equipment selection , and waste treatment. Keywords: Polyvinyl chloride polymer（PVC） Polyvinyl chloride Mass balance heat balance condensation reaction This is the preliminary design on the polymerization section of an annua output 100,000 tons of polyvinyl chloride ( PVC ) . In the paper a detailed overview about the research , production and application of PVC has been made , and the production process has been determined . In the design we adopt the suspension polymerization process , post-processing section in the no overflow stripping unit, and advanced cyclone drying plant. On the basis of the process, with SG -5 type PVC resin for example, the material balance , heat balance are calculated, and the choice of equipmentes, the waste treatment method are discussed. 目 录 摘 要………………………………………………………………………Ⅰ Abstract…………………………………………………………………Ⅰ 第1章 概述 1.1 概述 1.1.1 聚氯乙烯的性质与特点 1.1.2 聚氯乙烯的主要用途 1.1.3 国内外聚氯乙烯工业的发展 1.2 设计目的和意义 1.3 设计依据 1.4 设计规模与范围 1.4.1设计规模 1.4.2设计范围 1.5 原料与产品规格 1.5.1产品质量与规格 1.5.2主要原辅料规格 第2章 工艺论证与选择 2.1 PVC成产工艺 2.1．1 PVC成产工艺 2.1.2 聚合反应概述 2.2 生产工艺流程 2.2.1 反应原理 2.2.2工艺流程示意图 2.2.3 配方选择 2.2.4 进料方式 2.2.5加料系统 2.2.6 聚合系统 2.2.7 浆料汽提与废水汽提 2.2.8 干燥系统 第3部分 物料衡算与热量计算 3.1 物料衡算 3.1.1聚合釜物料衡算 3.1.2出料槽物料衡算 3.1.3 汽提塔物料衡算 3.1.4
