三甘醇（TEG）是一種無色透明的中性油狀液體，在加熱到280℃左右時，對高分子聚酯（PET）有醇解和溶解作用，三甘醇清洗爐利用這一特性，將粘附有高聚酯汙物的工件置於盛有TEG溶液的清洗槽內加熱沸騰，達到清洗的目的。
該設備採用不鏽鋼電加熱管組合加熱器，安裝在清洗槽底部的TEG溶液中直接加熱，升溫快、熱效率高，沸騰清洗效果好，設備結構簡單、操作方便。
設備結構有單缸位、雙缸位和多缸位連體形式，缸徑大，操作高度高的配置操作鋼平臺，並且爐蓋啓、閉有氣動開蓋配重裝置和螺桿升降三種開蓋供選擇，自動控溫裝置採用日本富士係列溫控儀程序控溫，固態繼電器觸發控製，控製部件均按防爆要求配置，工作性能穩定可靠。
本廠還配套生産提供三甘醇清洗後的後續清洗設備：水洗槽、堿洗槽、超聲波清洗槽、高壓水洗槽等。
BOPET、BOPA過濾器清洗裝置：三甘醇清洗爐、水洗槽、堿洗水洗槽、酸洗水洗槽、酸堿中和槽、超聲波清洗機、冒泡測試儀、碟片幹燥箱、濾芯翻轉架、過濾器預熱爐。
BOPET、BOPA過濾器清洗工藝：三甘醇爐清洗→水洗→堿洗水洗→酸洗水洗→超聲波清洗→冒泡測試→碟片幹燥→組裝預熱
TEG is a kind colorless transparent neutral oil liquid. When being heated to280'C or so. it has alcoholysis and dissolution to PET. TEG washing oven makes use of this characteristic. and work piece covered with PET filth is put in the cleaning tank with TEG solution and is heated to boiling, which achieves the goal of cleanup.
Teg washing oven. water washing tank. alkali &water washing tank. acid &water washing tank. acid-alkali neutralization tank. ultrasonic washing machine, bubble instrument. tray drying oven. filter core turnover shelf. filter pre-heater.
Teg washing→water washing→alkali &water washing→ acid &water washing→ultrasonic washing →bubble test -tray drying→ assembly preheating
