酒精回收
一、工作原理及应用范围介绍Introduction of Working Principle and Scope of Application
该设备是利用酒精沸点低于水及其溶液沸点的原理，用稍高于酒精沸点的温度，将需回收的酒精溶液进行加热蒸发，经塔体精馏后蒸发出高浓度酒精蒸气，再经冷凝器冷却回收，获得符合浓度要求的酒精。
适用于制药、轻工、化工等行业稀酒精自动回收，同时也适用于甲醇等其它溶媒的精馏。该系统可根据用户要求，将30度左右的稀酒精精馏至93度以上（体积浓度比）的酒精。
This principle that the boiling point of alcohol is lower than that of the water and solution is adopted by the equipment; the alcohol resolution to be recycled is heated for evaporation at the temperature higher than the boiling point of alcohol; the high-concentration alcohol steam is obtained after rectificationin the tower and obtained after being cooled by the cooler, finally obtaining the alcohol with required concentration.
It is applicable to automatic recycling of dilute alcohol of pharmacy, light industry and chemical industry and to therectification of methanol and other solvents. This system can rectify the dilute alcohol about 30 degree to the alcohol over 93 degree (volume concentration ratio) as required by the customer.
二、特点Characteristics
1. 连续式回收工艺，回收率大于95%，塔底废液中含料低，产品浓度稳定，蒸馏效率高，运行费用低，投资省。
2. 回收酒精后，本设备采用外加热自然循环与真空负压蒸发方式，蒸发速度快，浓缩比重大，液料在全密封无泡沫状态下进行浓缩。
3. 收膏时不需在加热器内进行，关闭加热器上下蝶阀，在蒸发器内底部收膏即可，比重可达1.35以上。
4. 本设备可自动排水，减轻劳动强度，有半自动化功能，定货时需注明是否需要自动排水。
1. The continuous recycling process is adopted to achieve over 95% of recovery rate, low material content of the waste liquor at the bottom of tower, stable concentration of product, high rectification efficiency, low operation cost and saving investment.
2. The external heating natural circulation and vacuum evaporation are adopted by the equipment after recycling the alcohol to provide the fast evaporation and high concentration ratio; the liquid is concentrated in fully sealed status without foam.
3. The extract collection is not required to be conducted in the heater, but can be conducted at the bottom of evaporator with upper and lower butterfly valves of heater closed; and the proportion is over 1.35.
4. The equipment is capable of discharging water automatically to reduce the labor intensity, and is provided with the semi-automatic function; it is required that whether the automatic discharge function is needed shall be noted when the order is placed.
