Abstract
The utility model discloses methanol and ethanol extracting equipment which comprises an evaporation boiler, a rectifying tower and a condenser, and also comprises an overhead condenser, wherein the cold water inlet of the overhead condenser is connected with a mother liquid storage tank through a transfer pump, the hot water outlet of the overhead condenser is connected with the liquid inlet of the evaporation boiler, the outlet of the evaporation boiler is connected with the inlet of the rectifying tower, the outlet of the rectifying tower is connected with the steam inlet of the overhead condenser, and the condensate outlet of the overhead condenser is connected with the condenser. As mother liquid is adopted for condensing steam, and simultaneously, the steam heats the mother liquid, not only is the steam quantity needed for heating the mother liquid saved, but also the use quantity of cooling water is saved, heat in the steam is fully utilized, the energy waste is reduced, and in addition, the operation stability is high because the mother liquid is heated.
Description
Technical field
The utility model relates to a kind of chemical industry and extracts equipment, especially a kind of first and second alcohol extracting equipment.
Background technology
When first and second alcohol being distilled extraction, need deliver to evaporation boiler to mother liquor usually and heat, the steam after the heating is delivered to rectifying column and is carried out rectifying, and the steam after the rectifying leads to condenser and carries out condensation.The temperature of mother liquor will heat, and carries out condensation and condenser will feed cold water, and the consumption of cooling water is very big, it is also very big to add the needed steam consumption of hot mother liquor, thereby caused the waste of the energy, and because the mother liquor temperature that feeds is low excessively, the poor stability of operation.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of first and second alcohol extracting equipment, makes full use of the heat in the steam, reduces energy waste.
For achieving the above object, the technical solution of the utility model is: a kind of first and second alcohol extracting equipment, comprise evaporation boiler, rectifying column, and condenser, the described first and second alcohol extracting equipment also comprise overhead condenser, the cooling water inlet of described overhead condenser links to each other with mother liquor holding tank by delivery pump, the hot water outlet of described overhead condenser links to each other with the inlet of described evaporation boiler, the outlet of described evaporation boiler links to each other with the import of described rectifying column, the outlet of described rectifying column links to each other with the steam inlet of described overhead condenser, and the condensate outlet of described overhead condenser links to each other with described condenser.
Further, the described first and second alcohol extracting equipment also comprise reboiler, and described reboiler links to each other with rectifying column.
Further, the described first and second alcohol extracting equipment also comprise cooler and dashpot, the import of described cooler links to each other with the condensate outlet of described condenser, and the outlet of described cooler links to each other with the import of described dashpot, and the outlet of described dashpot links to each other with pan tank with described rectifying column.
Adopt the beneficial effect of the technical program to be: adopt mother liquor that steam is carried out condensation, steam heats mother liquor simultaneously, has not only saved the quantity of the steam that adds the required usefulness of hot mother liquor but also has saved the consumption of cooling water.Make full use of the heat in the steam, reduce energy waste, and because mother liquor heats, the stability of operation is high.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is the schematic diagram of a kind of first and second alcohol extracting equipment of the present utility model.
The specific embodiment
As shown in Figure 1, the cooling water inlet of overhead condenser links to each other with mother liquor holding tank by delivery pump, the hot water outlet of overhead condenser links to each other with the inlet of evaporation boiler, the outlet of evaporation boiler links to each other with the import of rectifying column, the outlet of rectifying column links to each other with the steam inlet of overhead condenser, and the condensate outlet of overhead condenser links to each other with condenser.Reboiler links to each other with rectifying column.The import of cooler links to each other with the condensate outlet of condenser, and the outlet of cooler links to each other with the import of dashpot, and the outlet of dashpot links to each other with pan tank with rectifying column.During duty, mother liquor is delivered to the cooling water inlet of overhead condenser through delivery pump from mother liquor holding tank, through becoming temperature after the heat exchange of overhead condenser is mother liquor about 40～60 degrees centigrade, mother liquor about these 40～60 degrees centigrade is fed to and is heated into steam in the evaporation boiler and is sent to rectifying column, being sent to steam in the rectifying column enters at the bottom of by tower, carry out counter current contacting with decline liquid, two contact, volatile (low boiling) component in the decline liquid constantly shifts in steam, difficulty volatilization (higher boiling) component in the steam constantly shifts in decline liquid, steam is more near cat head, its volatile components concentration is higher, and decline liquid is healed near at the bottom of the tower, and its difficult volatile component is more enrichment then, reaches the purpose that component is separated.The steam that is risen by cat head enters overhead condenser, carry out heat exchange with the mother liquor that flows through in the overhead condenser, the liquid of condensation enters into cooler, other also uncooled steam continue to enter into condenser 2 and carry out time condensation, the condensate liquid of overhead condenser and condenser 2 cools off through subcooler, and a part is taken out remaining part as distillate and got to rectifying column as phegma with reflux pump.Pipeline in the middle of dashpot and the rectifying column is provided with sample tap, can carry out sample analysis to distillate.The liquid that tower bottom flow goes out, a part is wherein sent into reboiler, and after the thermal evaporation, steam returns in the tower, and another part liquid takes out as the still raffinate.
Adopt the beneficial effect of the technical program to be: adopt mother liquor that steam is carried out condensation, steam heats mother liquor simultaneously, has not only saved the quantity of the steam that adds the required usefulness of hot mother liquor but also has saved the consumption of cooling water.Make full use of the heat in the steam, reduce energy waste, and because mother liquor heats, the stability of operation is high.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
