如何使用蒸餾塔進行松脂加工
蒸餾塔是進行精(jing)餾的一種塔式(shi)汽液接觸裝置，主要(yao)作用是將液體混合物多次部(bu)分(fen)氣化和部(bu)分(fen)冷(leng)凝，利用其(qi)中各組(zu)份(fen)揮發度不同的特性(xing)，實現分(fen)離(li)的單元操作。
松(song)(song)香是一種流動透明的液體，存放(fang)日(ri)久，即為白(bai)色液體，經烈日(ri)曝曬后變成干涸的毛(mao)松(song)(song)香。但是松(song)(song)脂不直(zhi)接應用，主要是通過加熱(re)180- 195℃，分離出松(song)(song)香和(he)松(song)(song)節油。加工方法(fa)，可(ke)分為蒸汽法(fa)和(he)滴水法(fa)。
今天給(gei)大(da)家(jia)講一下如何使用蒸餾塔(ta)進行松脂(zhi)加(jia)工：
松(song)(song)(song)脂(zhi)(zhi)加工(gong)就是(shi)用(yong)水蒸(zheng)氣蒸(zheng)餾或(huo)其他方法(fa)將(jiang)松(song)(song)(song)脂(zhi)(zhi)分成松(song)(song)(song)節(jie)油和松(song)(song)(song)香的過程。松(song)(song)(song)脂(zhi)(zhi)中的揮發(fa)性(xing)物質為松(song)(song)(song)節(jie)油，非揮發(fa)性(xing)的熔合物為松(song)(song)(song)香。以前都是(shi)簡單地將(jiang)塊狀松(song)(song)(song)脂(zhi)(zhi)放入蒸(zheng)餾釜內，用(yong)直接火加熱(re)煉(lian)制。由于松(song)(song)(song)脂(zhi)(zhi)含油少，雜質和氧化樹脂(zhi)(zhi)多，加工(gong)所(suo)得的松(song)(song)(song)節(jie)油收(shou)率低(di)，松(song)(song)(song)香質量差。
用水蒸氣蒸餾或(huo)其他方法將松(song)脂分成松(song)節(jie)油(you)和松(song)香的過程。松(song)脂中的揮發(fa)性物(wu)質為松(song)節(jie)油(you)，非揮發(fa)性的熔合物(wu)為松(song)香。
加工(gong)方法：
包括松脂(zhi)(zhi)貯存、輸送(song)、蒸(zheng)(zheng)餾(liu)。松脂(zhi)(zhi)加工(gong)(gong)(gong)廠備有貯脂(zhi)(zhi)池(chi)(chi)，以便按(an)計(ji)劃連續生產。加工(gong)(gong)(gong)時用螺(luo)旋輸送(song)機將(jiang)池(chi)(chi)中松脂(zhi)(zhi)送(song)至(zhi)(zhi)料斗(dou)進行加工(gong)(gong)(gong)。規模(mo)較大的工(gong)(gong)(gong)廠，貯脂(zhi)(zhi)池(chi)(chi)離(li)加工(gong)(gong)(gong)車(che)間較遠(yuan)，松脂(zhi)(zhi)通過管道用壓縮(suo)空氣送(song)至(zhi)(zhi)車(che)間料斗(dou)。蒸(zheng)(zheng)餾(liu)塔蒸(zheng)(zheng)餾(liu)工(gong)(gong)(gong)藝分連續水蒸(zheng)(zheng)氣蒸(zheng)(zheng)餾(liu)法、間歇(xie)水蒸(zheng)(zheng)氣法和簡易加工(gong)(gong)(gong)法3種(zhong)。
