Abstract
A rectifying tower for ethanol purification and production comprises tower segments, filler, a liquid distributor, a tower bottom, a tower bottom heater, a secondary gas outlet and a raffinate outlet. The utility model is characterized in that an externally cycling heater is disposed outside the rectifying tower with the built-in tower bottom heater. The utility model has the advantages that the rectifying tower is suitable for batch production with small quantity and continuous production with large quantity, and can remarkably reduce operating cost and improve the equipment utilization ratio and production efficiency. Compared with the single-heater production manner, the production capacity of the double-heater production manner is improved by 8-15%, the raffinate effluent concentration can be controlled less than or equal to 1%, up 2-4%, and the work efficiency is improved by 20%.
Description
(1) technical field
The utility model relates to a kind of rectifying column, particularly a kind of rectifying column that is used for ethanol purification production.
(2) background technology
In traditional pharmaceutical manufacturing, often need 93% above high concentration ethanol as extractant, and can produce a large amount of Different concentrations of alcohol weak solutions again after using, for energy-conservation, consumption reduction and reclaim again and utilize, adopt usually and alcohol dilute solution is carried out rectification and purification use again.
Two kinds of production methods are arranged at present, i.e. Batch Process and production continuously in pharmacy corporation:
1. the capital equipment of batch fractionating comprises tower joint, filler, tower still and tower kettle heater, its production process is that 30% above Diluted Alcohol carries out Batch Process for adding concentration to the tower still in batches, regulate recovery and return flow ratio according to tower still, tower top temperature, reclaim concentration and be the high concentration ethanol more than 93%, this mode is only applicable to the production of small lot, residual liquid discharge concentration is controlled at below 3%, and power consumption and production efficiency are low.
2. the capital equipment of continuous rectification comprises tower, filler, outer circulation heater, its production process is for being 30% Diluted Alcohol heating back feed liquor continuously by tower outer loop heater with concentration, regulate constant recovery and return flow ratio according to tower still, tower top temperature, reclaim concentration and be the high concentration ethanol more than 93%, this mode is applicable to production continuously in enormous quantities, residual liquid discharge concentration is controlled at below 5%, and running expense is corresponding with cost higher.
(3) utility model content
The purpose of this utility model is at the problems referred to above, provide a kind of production efficiency height, running expense low, not only be suitable for the production of small lot intermittently but also can adapt to quantity-produced and be used for the rectifying column that ethanol is purified and produced.
The technical solution of the utility model:
A kind of rectifying column that is used for ethanol purification production is made up of tower joint, filler, liquid distribution trough, tower still and tower kettle heater, the outlet of secondary gas and raffinate outlet, it is characterized in that: at the rectifying column outer setting outer circulation heater of built-in tower kettle heater.
The utility model has the advantages that: not only be suitable for intermittently small lot batch manufacture but also can adapt to production continuously in enormous quantities, can reduce operating cost greatly, improve utilization rate of equipment and installations and production efficiency:
1. when two kinds of mode of heatings used simultaneously, its production capacity improved 8%-15% than the continuous mode of production;
2. when two kinds of mode of heatings used simultaneously, its residual liquid discharge concentration≤1% improved 2% to 4% than reaching the Batch Process mode continuously;
3. when two kinds of mode of heatings used simultaneously, its operating efficiency improved 20% than the continuous mode of production.
(4) description of drawings
A kind of rectifying column structural representation that is used for ethanol purification production.
Among the figure: 1. the secondary gas exports 2. towers and saves 3. filler 4. liquid distribution troughs, 5. tower stills and the outlet of tower kettle heater 6. outer circulation heaters 7. Diluted Alcohol imports 8. raffinates
(5) specific embodiment
A kind of rectifying column that is used for ethanol purification production, form by tower joint 2, filler 3, liquid distribution trough 4, tower still and tower kettle heater 5, the outlet 1 of secondary gas and raffinate outlet 8, it is characterized in that: at the rectifying column outer setting outer circulation heater of built-in tower kettle heater.Concrete technological process: alcohol dilute solution enters 6 preheatings of outer circulation heater from ethanolic solution import 7, saves then to enter from rectifying column, changes the feed liquor mode through liquid distribution trough 4; The alcohol gas that distillation process produces enters condenser liquefaction after cat head secondary air outlet 1 is discharged; Raffinate continues heating at the tower still by still internal heater 5 purifies, and raffinate is discharged by raffinate outlet 8.This rectifying column new medicine company group in Tianjin is applied to be designed to the purification of 400L/h ethanol and produces, test result shows: Diluted Alcohol feed liquor concentration is 30%, reclaim concentration of alcohol and can reach 95%, residual liquid discharge concentration≤1%, and actual production capacity reaches 580L/h, obtains good economic technology and environmental benefit.
Claims (1)
1. one kind is used for the rectifying column that ethanol is purified and produced, form by tower joint, filler, liquid distribution trough, tower still and tower kettle heater, the outlet of secondary gas and raffinate outlet, it is characterized in that: at the rectifying column outer setting outer circulation heater of built-in tower kettle heater.
