【摘要】：近年來，由于國內(nèi)聚氯乙烯的產(chǎn)能擴(kuò)張過于迅速，加之世界范圍的經(jīng)濟(jì)危機(jī)以及房地產(chǎn)行業(yè)的不景氣，使得聚氯乙烯產(chǎn)能大大多于市場需求，行業(yè)開工率維持在50％～60％，市場價格低位運(yùn)行，幾乎是全行業(yè)虧損狀態(tài)，因此，一些技術(shù)實(shí)力較強(qiáng)的企業(yè)逐漸減少常規(guī)樹脂的生產(chǎn)，，轉(zhuǎn)而生產(chǎn)利潤率較高的特種樹脂。 本設(shè)計(jì)是年產(chǎn)一萬噸特種聚氯乙烯（PVC）聚合工段初步設(shè)計(jì)，主要針對目前已經(jīng)生產(chǎn)普通型聚氯乙烯的廠家作為新增裝置。本文對普通及特種聚氯乙烯的市場、生產(chǎn)技術(shù)以及應(yīng)用情況進(jìn)行了詳細(xì)的概述，確定了聚氯乙烯的生產(chǎn)工藝。在確定生產(chǎn)工藝的基礎(chǔ)上進(jìn)行了物料衡算、熱量衡算、設(shè)備選型等。本設(shè)計(jì)充分考慮了特種樹脂生產(chǎn)工藝條件的特殊性。本設(shè)計(jì)具有較強(qiáng)的溫度、壓力適應(yīng)范圍，采用了特殊的原料加入工藝，適用于生產(chǎn)指定的特種樹脂品種。
[Abstract]:In recent years, due to the rapid expansion of domestic PVC production capacity, coupled with the worldwide economic crisis and the recession in the real estate industry, the production capacity of PVC has greatly exceeded market demand. The operating rate of the industry is maintained at 50% and 60%, and the market price is low, which is almost the loss state of the whole industry. Therefore, some enterprises with strong technical strength gradually reduce the production of conventional resins and turn to produce special resins with higher profit margins. This design is a preliminary design of the polymerization section with an annual production capacity of 10,000 tons of special PVC / PVC, which is mainly aimed at the manufacturers that have already produced common PVC at present as a new installation. In this paper, the market, production technology and application of general and special PVC are summarized in detail, and the production process of PVC is determined. On the basis of determining the production process, material balance, heat balance, equipment selection and so on are carried out. This design fully considered the particularity of the special resin production process conditions. This design has a strong temperature, pressure range, the use of special raw material addition process, suitable for the production of designated special resin varieties.
