  酒精回收塔安裝時，應(yīng)保證塔身的垂直，其垂直度偏差要求小于1.5‰，本設(shè)備操作為連續(xù)式進料，當排除塔釜殘液時，釜內(nèi)必須呈常壓，以免造成真空損壞設(shè)備?；厥樟啃∫嗫砷g隙操用。酒精回收塔在生產(chǎn)過程中，開始時把稀酒精母液進到貯罐內(nèi)，再打開閥門進到加熱塔釜中，稀酒精在塔釜內(nèi)不超于視鏡，后打開蒸氣閥門加熱，利用酒精和水沸點的不同，使酒精和部份水蒸發(fā)，酒精、水和混合蒸汽經(jīng)塔身物料上升，在上升過程中，溫度逐漸下降使部份內(nèi)回流，大部份酒精蒸汽經(jīng)塔頂連通管道至冷凝為冷濃酒精，取樣化驗合格，經(jīng)冷卻器出現(xiàn)料，否則就回流塔釜再蒸餾。
Alcohol recovery tower, when installation should guarantee the towers are vertical, the verticality deviation request is less than 1.5 ‰, the equipment for continuous feeding operation, when removing tower kettle residual liquid, must be within the kettle in atmospheric pressure, so as not to cause damage to the vacuum equipment. Where little fuck with clearance. Alcohol recovery tower in the process of production, at the beginning of the dilute alcohol liquor into the storage tank, and then open the valve into the heating tower kettle, dilute alcohol within the tower kettle is not beyond sight glasses, finally opened the heating steam valve, the use of alcohol and water boiling point is different, make the alcohol and water evaporation, alcohol, water, and mixed steam through the tower material rise, in the process of rising, the drop in temperature gradually internal reflux, most of the alcohol steam via the tower connecting pipes to condense for cold alcohol concentration, the sample test qualified, will be cooler there, otherwise, reflux column reactor and distillation.

 

 

酒精回收塔操作注意事項：

1、冷卻水要下進上出。

2、次加熱時間約40--60分鐘加至溫度80-100℃，以后可連續(xù)性進料和出料。
