Abstract
The utility model discloses an alcohol recovery system. The alcohol recovery tower is provided with a direct steam inlet, and the direct steam inlet is arranged on the lower part of the tower. The alcohol recovery system can reduce energy consumption by a large margin, and therefore a better economic benefit is achieved. Meanwhile, yield of wine recovery can be increased by 1% to 2%, consumption of ethanol raw material can be reduced by 1.5%, organic content in waste water of the alcohol recovery tower is reduced to achieve discharge requirement, and sewage treatment cost is lowered.
Description
Technical field
The utility model belongs to the chemical production equipment field, relates to the production equipment of the raw material acetaldehyde of pentaerythrite, relates in particular to a kind of alcohol recovery system.
Background technology
Pentaerythrite is important organic chemical industry's intermediate and fine chemical product, has obtained in a lot of fields using widely.Pentaerythrite is to be generated under the catalytic reaction of alkali by formaldehyde and acetaldehyde.Wherein raw material acetaldehyde then is to be generated by oxidation of ethanol, the rare acetaldehyde that in commercial production, generates after the oxidation of ethanol, and rare acetaldehyde is through obtaining dense acetaldehyde after the rectifying; Remaining waste liquid reclaims ethanol through alcohol distillation column; But existing alcohol distillation column steam need get into alcohol distillation column through heater heating back, causes the waste of the energy on the one hand, and the rate of recovery of alcohol is not high on the other hand; COD in the waste water reaches more than 5000, also needs further to handle and could discharge.
The utility model content
The utility model reclaims inadequate problem to alcohol in the existing acetaldehyde production, provides a kind of through improved alcohol recovery system, can make the consumption of alcohol recovery system minimizing energy, improves the rate of recovery of alcohol, reduces the COD of waste water.
The technical scheme of the utility model is: a kind of alcohol recovery system, comprise alcohol distillation column, and said alcohol distillation column has the live (open) steam import, and the live (open) steam import is arranged on the bottom of body of the tower.Steam directly gets into alcohol distillation column, does not need to pass through heater again, has reduced the consumption of energy.
Have the alcohol outlet on the said alcohol distillation column, be arranged on the top of alcohol distillation column.
Said alcohol recovery system comprises condenser, reflow of alcohol feeder, alcohol extraction pump and valve; The import of condenser is connected with the outlet of the alcohol of alcohol distillation column; The outlet of condenser is connected with the reflow of alcohol feeder, and the reflow of alcohol feeder is connected with alcohol distillation column with valve through alcohol extraction pump.
The alcohol distillation column bottom is provided with waste liquid outlet.
Alcohol recovery system through the utility model; Can reduce energy resource consumption significantly; Therefore favorable economic benefit is arranged, return wine (being ethanol) yield simultaneously and can improve 1%-2%, feed ethanol consumption reduces by 1.5%; The content of organics reduction reaches emission request in the alcohol distillation column waste water, has reduced cost of sewage disposal.
Description of drawings
Fig. 1 is the structural representation of existing alcohol recovery system.
Fig. 2 is the structural representation of the alcohol recovery system of the utility model.
The specific embodiment
Be described in detail below in conjunction with the structure of accompanying drawing the utility model.
As shown in Figure 1, existing alcohol recovery system also is provided with a heater 2 ' on the alcohol distillation column 1 ' body of the tower, and steam gets into alcohol distillation column 1 ' again through heater 2 '.
As shown in Figure 2, the alcohol recovery system of the utility model comprises alcohol distillation column 1, and alcohol distillation column 1 has the live (open) steam import, and the direct import of steam is arranged on the bottom of body of the tower, and steam directly gets into alcohol distillation column 1.
Have the alcohol outlet on the alcohol distillation column 1, be arranged on the top of alcohol distillation column 1.The alcohol outlet of alcohol distillation column 1 is connected with the import of condenser 2, and the outlet of condenser 2 is connected with the import of reflow of alcohol feeder 3, and reflow of alcohol feeder 3 is connected with alcohol distillation column 1 with valve 5 through alcohol extraction pump 4.
The material of last operation gets in the alcohol distillation column 1 through the material inlet of alcohol distillation column 1, and steam directly gets into alcohol distillation column 1 through the direct import of the steam of alcohol distillation column 1; The alcohol that reclaims gets into reflow of alcohol feeder 3 after getting into condenser 2 condensations through the alcohol outlet; And the reflow of alcohol of reflow of alcohol feeder 3 is gone in the alcohol distillation column 1, treats that the alcohol concentration in the reflow of alcohol feeder 3 reaches setting value then through alcohol extraction pump 4 and valve 5 extraction.
The waste liquid that after reclaiming, produces is then discharged by 6 extraction of waste liquid extraction pump through the waste liquid outlet of alcohol distillation column 1, reaches discharge standard.
Claims (4)
1. an alcohol recovery system comprises alcohol distillation column, it is characterized in that, said alcohol distillation column has the live (open) steam import, and the live (open) steam import is arranged on the bottom of body of the tower.
2. alcohol recovery system according to claim 1 is characterized in that, has the alcohol outlet on the said alcohol distillation column, is arranged on the top of alcohol distillation column.
3. alcohol recovery system according to claim 2; It is characterized in that; Said alcohol recovery system comprises condenser, reflow of alcohol feeder, alcohol extraction pump and valve; The import of condenser is connected with the outlet of the alcohol of alcohol distillation column, and the outlet of condenser is connected with the reflow of alcohol feeder, and the reflow of alcohol feeder is connected with alcohol distillation column with valve through alcohol extraction pump.
4. alcohol recovery system according to claim 1 is characterized in that, the alcohol distillation column bottom is provided with waste liquid outlet.
