酒精回收塔操作時(shí)需要注意事項(xiàng)
酒精回收塔安裝時(shí)，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(jìn)料，當(dāng)排除塔釜?dú)堃簳r(shí)，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(guò)程中，開(kāi)始時(shí)把稀酒精母液進(jìn)到貯罐內(nèi)，再打開(kāi)閥門(mén)進(jìn)到加熱塔釜中，稀酒精在塔釜內(nèi)不超于視鏡，后打開(kāi)蒸氣閥門(mén)加熱，利用酒精和水沸點(diǎn)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(guò)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(yàn)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(xiàng)：
1、冷卻水要下進(jìn)上出。
2、次加熱時(shí)間約40--60分鐘加至溫度80-100℃，以后可連續(xù)性進(jìn)料和出料。
1, the cooling water into the out.
2, for the first time, heating time, about 40-60 minutes to temperature at 80-100 ℃, can be continuous feeding and discharging in the future.
