The absorption tower is connected in series with cooler, fan and heater by pipeline. Exit of the absorption tower is connected with entrance of the cooler, and entrance of the absorption tower is connected with exit of the heater. The cooler can be made up of two-grade or three-grade coolers connected in series. Exit of the absorption tower is connected with entrance of first-grade cooler. The utility model has advantages of simply structure, low energy consumption and good effect of energy saving.
Description
Technical field
The utility model belongs to the fuel ethanol production technical field, particularly a kind of ethanol dehydration adsorption tower adsorbent reactivation device.
Background technology
At present, in alcohol industry is produced, need through distillation workshop section as single-minded from the fermenting-ripening wine with dregs to finished wine.Distillation workshop section is the workshop section of energy consumption maximum, accounts for alcohol (this moment, 95% (W) alcohol was finished product) and produces about 60% of total energy consumption.The method of absolute ethyl alcohol preparation can reduce two big classes: rectification method and absorption method.Rectification method is divided into azeotropic dehydration, ion-exchange evaporation again and adds dehydration of salt method etc.The used energy consumption of this azeotropic distillation accounts for about 1/3 of whole absolute ethyl alcohol production process total energy consumption, and therefore this method energy consumption is too high, also has pollutant emission simultaneously; Absorption method is different because of used adsorbent, is that adsorbent dewaters with lime, sodium metal, silica gel, molecular sieve, cereal generally.This method has the advantages that energy consumption is low, the production process three wastes are few and production cost is low, uses more and more widely.Sorbent used regeneration generally adopts decompressor to carry out, and makes the adsorbed water desorption by decompression, the reclaim equiment complexity, and energy consumption is higher.
The utility model content
The utility model purpose with the ethanol dehydration adsorption tower adsorbent reactivation that a kind of equipment is simple, energy consumption is low device is provided.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: ethanol dehydration adsorption tower adsorbent reactivation device, comprise adsorption tower, be in series by pipeline that the adsorption tower outlet connects cooler inlet, import connects heater outlet by adsorption tower, cooler, blower fan and heater.
Cooler is made up of the one-level cooler and the secondary coolers of mutual series connection, be provided with the two-way regeneration gas passage that carries out heat exchange mutually in the one-level cooler, be provided with the refrigerant passage and the regeneration gas passage that carry out heat exchange mutually in the secondary coolers, one road regeneration gas passage of the one-level cooler that is connected with the adsorption tower outlet is connected with the regeneration gas passage of secondary coolers, the regeneration gas passage of secondary coolers is connected with two road regeneration gas passages of one-level cooler, and the one-level cooler is connected with blower fan and heater by two road regeneration gas passages; Be provided with the alcohol vapor passage and the regeneration gas passage of mutual heat exchange in the heater.
Be serially connected with precooler on the pipeline between adsorption tower and the one-level cooler, be provided with cooling-water duct and regeneration gas passage in the precooler, one road regeneration gas channel connection of this regeneration gas passage and adsorption tower outlet and one-level cooler.
In the utility model, complete equipment is made up of adsorption tower and regenerative system, and regenerative system can be composed in series by three grades of coolers, blower fan and heaters, and cooler, blower fan are conventional equipment, and equipment is simple, invests little; Adopt the freezing method of drying of cooling medium to handle the regeneration carrier gas of adsorption tower by cooler, its desorption water condensation that carries is removed, the regeneration carrier gas is sent in the heater by blower fan and is heated.Precooler makes the preliminary cooling dehumidification of regeneration carrier gas, secondary coolers utilize refrigerant to make regeneration carrier gas degree of depth cooling dehumidification, this regeneration carrier gas make the regeneration gas cooling dehumidification through precooling through one-level cooler one road regeneration gas passage conversely again with cooling water, regeneration gas progressively carries out cooling dehumidification through precooler, one-level cooler, secondary coolers, and cooling condensation dries effective.The heating of regeneration carrier gas is provided by the low-grade heat that alcohol steam carries, and can realize that waste heat utilizes again.Enter adsorption tower after the regeneration carrier gas heating and regenerate, the regeneration carrier gas can be air, CO
2, N
2Deng inert gas.Do not need big power in the regenerative process, energy resource consumption is little.This technology is applicable to the living beings of all alcohol production raw materials,
