酒精回收塔操作时需要注意事项

  酒精回收塔安装时,应保证塔身的垂直,其垂直度偏差要求小于1.5‰,本设备操作为连续式进料,当排除塔釜残液时,釜内必须呈常压,以免造成真空损坏设备。回收量小亦可间隙操用。酒精回收塔在生产过程中,开始时把稀酒精母液进到贮罐内,再打开阀门进到加热塔釜中,稀酒精在塔釜内不超于视镜,最后打开蒸气阀门加热,利用酒精和水沸点的不同,使酒精和部份水蒸发,酒精、水和混合蒸汽经塔身物料上升,在上升过程中,温度逐渐下降使部份内回流,大部份酒精蒸汽经塔顶连通管道至冷凝为冷浓酒精,取样化验合格,经冷却器出现料,否则就回流塔釜再蒸馏。
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项:
1、冷却水要下进上出。
2、第一次加热时间约40--60分钟加至温度80-100℃,以后可连续性进料和出料。
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.
