聚酯工藝是一種使用合成原料生產合成纖維的工藝技術。鑒于低吸水率,染色困難和容易產生靜電的缺點,用于在聚酯工廠中應用真空系統。酯類在中國三大合成纖維行業中占有舉足輕重的地位。因此,解決聚酯問題等同于幫助合成纖維工業更好地發展。
隨著聚酯技術(shu)水平的(de)(de)(de)不斷提高,許多制造商將根據他們不同的(de)(de)(de)工(gong)藝(yi)特點和(he)操作經驗繼(ji)續改進真(zhen)空(kong)系統,以有(you)效減少(shao)真(zhen)空(kong)管的(de)(de)(de)堵塞(sai)并減少(shao)有(you)機物的(de)(de)(de)排(pai)放(fang)。確(que)保了真(zhen)空(kong)系統的(de)(de)(de)長期穩定(ding)運(yun)行。
聚(ju)酯(zhi)裝置真(zhen)空(kong)(kong)(kong)(kong)系統中使用的(de)真(zhen)空(kong)(kong)(kong)(kong)泵主要(yao)是旋(xuan)片真(zhen)空(kong)(kong)(kong)(kong)泵和(he)羅茨(ci)真(zhen)空(kong)(kong)(kong)(kong)泵。不(bu)同(tong)的(de)聚(ju)酯(zhi)工藝對真(zhen)空(kong)(kong)(kong)(kong)的(de)要(yao)求(qiu)不(bu)同(tong),可以在不(bu)同(tong)的(de)真(zhen)空(kong)(kong)(kong)(kong)控制(zhi)模式(shi)下(xia)使用。
真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)是(shi)用于獲(huo)得特(te)定(ding)要(yao)求的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)的(de)抽氣系統(tong)。真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)實際上是(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)裝(zhuang)置(zhi)(zhi)(zhi)的(de)相(xiang)似名稱(cheng)。真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)裝(zhuang)置(zhi)(zhi)(zhi)是(shi)一(yi)個由多個真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)組成(cheng)的(de)閉環真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)裝(zhuang)置(zhi)(zhi)(zhi)。它(ta)沒有(you)某些設備,例(li)如(ru)散(san)熱(re)器(qi)(qi)和冷凝器(qi)(qi)。真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)系統(tong)通常被稱(cheng)為完整的(de)組件(jian)范圍。它(ta)是(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng),真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)計,真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)箱(xiang),控(kong)制集(ji)成(cheng)箱(xiang)以及諸如(ru)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)閥,冷阱(jing)等(deng)其他組件(jian),它(ta)們(men)根據(ju)某些要(yao)求通過真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)管組合在(zai)一(yi)起,并具有(you)需(xu)要(yao)抽吸(xi)功(gong)能(neng)的(de)抽吸(xi)裝(zhuang)置(zhi)(zhi)(zhi)。它(ta)的(de)功(gong)能(neng)是(shi)在(zai)指定(ding)的(de)時間和空(kong)(kong)(kong)(kong)(kong)間獲(huo)得真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong),保持真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong),并確保在(zai)系統(tong)中實施(shi)過程或物理過程。
聚酯裝(zhuang)置的真(zhen)(zhen)空系統的功能(neng)是除(chu)去縮聚反應(ying)中生成的乙(yi)二醇(EG),沿鏈(lian)增長方向(xiang)進行反應(ying),并(bing)提取反應(ying)中生成的少量(liang)水(shui)和醛(quan)。其(qi)他不可(ke)冷(leng)凝的氣體(ti)可(ke)提供(gong)反應(ying)所需的真(zhen)(zhen)空條件,以確保產品質量(liang)。
在整個聚酯裝置中,真空系統與人體的呼吸系統一樣重要。在聚酯生產的后期,縮聚反應和降解反應基本達到平衡狀態。為了使正反應順利進行,必須將反應產生的小分子物質通過真空作用連續地從體系中除去,從而獲得更好的反應效果。生產(chan)(chan)高粘度聚酯產(chan)(chan)品。
