工業(yè) 中， 首先要 從 二氯乙烷（ EDC） 裂解得到氯乙烯 （ VCM） ， 再 由氯乙烯聚合得到聚氯乙烯 （ PVC） 產(chǎn)品。而在整個生產(chǎn)中二氯乙烷 （ EDC）裂解爐和氯乙烯（ VCM）聚合釜是生產(chǎn)中兩個 最 重要的設(shè)備，其生產(chǎn)運(yùn)行好壞直接影響著聚氯乙烯 （ PVC） 的質(zhì)量和產(chǎn)量 。本設(shè)計(jì)經(jīng)過對各種工業(yè)生產(chǎn)工藝 的 研究， 提出了一些改進(jìn)措施， 設(shè)計(jì)了年產(chǎn) 8 萬噸 氯乙烯 （ VCM） 裂解爐 和 聚 氯乙烯 （ PVC） 聚合釜 的主體設(shè)備大小及尺寸 ， 并 選擇了聚合釜的主體材質(zhì)。 關(guān)鍵詞 氯乙烯 (VCM)； 聚氯乙烯 (PVC)； 裂解爐 ； 聚合釜 II The Synthesis Device Process Design of Annual Output of 80,000 Tons of Vinyl Chloride and Polyvinyl Chloride Feng Song Grade 2020, Chemical Engineering and Technology, School of Chemical and Environmental Engineering, Chongqing Three Ges University Wanzhou, Chongqing 404000 Abstract: In the production of polyvinyl chloride (PVC) in oxychlorination, vinyl chloride (VCM) can be got from the pyrolysis of the ethylene dichloride (EDC), and then polyvinyl chloride (PVC) products can be got from the polymerization of vinyl chloride (VCM). In the whole production, ethylene dichloride (EDC) cracking furnace and vinyl chloride (VCM) polymerizer are the two most important equipments, which run a direct impact on the quality and output of PVC. This paper studied various industrial production processes, proposed some measures to improve, and designe
