【正文】 1 年產(chǎn) 5 萬噸聚氯乙烯的氯乙烯合成工段 工藝設(shè)計 摘要 ： 本設(shè)計是年產(chǎn) 5 萬噸聚氯乙烯的氯乙烯合成工段的初步工藝設(shè)計，本設(shè)計根據(jù)株洲化工集團現(xiàn)場實習(xí)有關(guān)資料及有關(guān)文獻，完成物料衡算、熱量衡算。此設(shè)計配有說明書一份、圖紙三份。 說明書內(nèi)容： 1． PVC 和 VC 的發(fā)展及發(fā)展趨勢。 2．合成工段的生產(chǎn)原理、流程。 3．物料衡算、熱量衡算。 4．主要設(shè)備的設(shè)計和選型． 5．三廢處理安全與安全技術(shù)。 三副圖紙： 1．帶控制點的物料流程圖。 2．車間平面布置圖。 3．主要設(shè)備的裝配圖。 關(guān)鍵詞 ： 合成、 PVC、 VC、工藝、設(shè)計。 The Preliminary Design about the Synthesis Construction Section of Vinyl Chloride of PVC 50000 tons per year Speciality: Chemical engineering amp。 technology Author: Su Lin Supervisor: Zeng Wennan Abstract:This graducation design is a primary designed about synthesis construction section of vinyl chloride of PVC 50000 tons every to the Zhuzhou chemical industry group scene practice pertinent dates and related dates,the design was pleted with the calculation of the balance of material and heat the sign,the instruction booklet and three diagrams have been worked out． The main contention of the instruction booklet can be briefly illustrated as follows: development history of producing PVC amp。VC and its production way to produce calculation of the balance of material and calculation of heat design and choice about the main disposal of three wastes processing security and fire protection technology. There are three diagrams as follows: technique flow chart with controlled factory floorplan main equipment installing picture. Key words:synthesis、 PVC、 VC、 technological、 design. 2 目錄 中文摘要 英文摘要 前言 1 緒論 ............................................................................................................................................5 聚氯乙烯 (PVC)..........................................................................................................................5 聚氯乙烯工業(yè)的發(fā)展概況 ........................................................................................................5 聚氯乙烯工業(yè)在國民經(jīng)濟中的作用 ..........................................................................................6 聚氯乙烯系列聚合物的性質(zhì) ....................................................................................................6 聚氯乙烯制品的開發(fā)與應(yīng)用技術(shù) ...........................................................................................7 聚氯乙烯合成方法 ..................................................................................................................8 氯乙烯（ VC） ........................................................................................................................ 12 氯乙烯的合成 ....................................................................................................................... 12 生產(chǎn)工藝流程簡述 ................................................................................................................ 15 主要工藝參數(shù) ....................................................................................................................... 16 主要原料和產(chǎn)物的物化性質(zhì) .................................................................................................. 16 2 工藝計算 ................................................................................................................................... 18 物料衡算 ................................................................................................................................. 18 計算依據(jù) .............................................................................................................................. 18 計算 ..................................................................................................................................... 19 熱量衡算 ................................................................................................................................. 26 衡算方法 .............................................................................................................................. 26 標(biāo)況下有關(guān)物化數(shù)據(jù)表 ......................................................................................................... 27 計算 ..................................................................................................................................... 27 3 主要設(shè)備的設(shè)計與選型 .............................................................................................................. 34 石墨冷卻器的選型 ................................................................................................................... 34 已知條件 .............................................................................................................................. 34 計算兩流體的平均溫度差 ...................................................................................................... 34 石墨預(yù)熱器的選型 ................................................................................................................... 35 已知條件 .............................................................................................................................. 35 計算兩流體的平均溫度差 ...................................................................................................... 35 石墨冷卻器Ⅱ的選型 ............................................................................................................... 36 已知條件 .............................................................................................................................. 36 計算兩流體的平均溫度差 ...................................................................................................... 36 轉(zhuǎn)化器的設(shè)計 .......................................................................................................................... 37 已知條件 .............................................................................................................................. 37 3 計算 ..................................................................................................................................... 37 手孔 .................................................................................................................................
