The utility model is designed to produce rectified ethyl alcohol from brew, yeast sediment mixed with grains and condensed vinasse and can be used in alcohol production.

Known resource-saving continuous installation for producing rectified alcohol, grains and condensed vinasse from the mash (RF Patent for Utility Model No. 85357 Resource-saving continuous installation for producing ethyl rectified alcohol, grains and condensed vinasse from the mash / E.N. Konstantinov, T.G. .Korotkova, L.M. Levashova, A.V. Kiknadze according to the application No. 2009109426; Registered March 16, 2009. Publish. August 10, 2009 Bull. No. 24), consisting of a mixer of mash with water, mash, epure, alcohol columns reflux condensers and remote boilers for these columns, a decanter, a double-shell evaporator and a secondary steam collector of the 2nd stage of the evaporator.

The installation allows you to get rectified ethyl alcohol corresponding to the brand "Lux" according to GOST R 51652-2000, grains and condensed vinasse and provides heat recovery of the secondary steam of the evaporator.

The disadvantage of this installation is the increased consumption of heating steam from the boiler room for heating the mash column and the need to maintain in the first and second buildings a two-case evaporator installation of high pressure, and, consequently, a high boiling point of bard, which negatively affects the quality of one stripped bard.

The closest to the claimed of the known installations is a continuous operation for simultaneous production of rectified ethyl alcohol, grains and condensed vinasse from the mash (RF Patent for utility model No. 106554 Resource-saving continuous installation for the production of rectified ethyl alcohol, grains and condensed bard / L .M. Levashova, Kh.R. Siyukhov, T.G. Korotkova, E.N. Konstantinov on the application No. 2011113434/05 dated 01/13/2011. Registered on July 20, 2011. Published on July 20, 2011 Bull. No. 20) consisting of mash, epuration, alcohol columns n, reflux condensers, condensers and remote boilers for these columns, a double-shell evaporator, a secondary steam collector with five fittings, on the bard recycling line of a bard circulation pump and a remote reboiler column installed in series, on the carbon dioxide removal line from the condenser of the bottled column - separator equipped with lower side fitting for carbon dioxide input, upper side fitting for introducing hydroselective water, lower fitting for draining water into the annulus condenser, the upper fitting for the removal of carbon dioxide to the vacuum pump, on the supply line of the stillage for evaporation - decanter.

The installation allows you to get rectified ethyl alcohol, pellet and condensed vinasse from the mash and recover the heat of the secondary steam of the evaporator.

The disadvantage of this installation is the increased consumption of heating steam from the boiler room for heating the alcohol column and the need to maintain high pressure, and, therefore, a high boiling point of bard, in the first building of the double-shell evaporator, which negatively affects the quality of one stripped bard.

The objective of the utility model is to develop the design of a resource-saving continuous-use plant that ensures that rectified alcohol that meets the Lux brand in accordance with GOST R 51652-2000, pellets with a high protein content and a condensed stillage of high feed value are obtained from the mash.

The technical result of the utility model is to reduce the consumption of heating steam and to obtain a condensed stillage of increased feed value.

The technical result is achieved by the fact that a resource-saving installation of continuous operation for obtaining rectified alcohol, pellets and thickened stillage of high feed value from the mash contains mash, epure, alcohol columns, reflux condensers, condensers and external boilers for these columns, sequentially installed on the bard recirculation line, a circulation pump bards and an external reboiler for the bottled column; on the line of carbon dioxide removal from the condenser of the bottled column, a separator equipped with a lower side piece with carbon dioxide inlet, upper side nozzle for introducing hydroselective water, lower nozzle for draining water into the annulus of the condenser, upper nozzle for removing carbon dioxide to the vacuum pump, a decanter is installed on the bard supply line for evaporation, an evaporator is installed sequentially after the decanter, rotary compressor for compressing secondary steam and a secondary steam collector with five fittings: the first fitting for supplying a compressed secondary steam to the collector, the second for supplying compressed second steam from the collector to the external reboiler of the wash column, the third to supply the compressed second steam from the collector to the remote boiler of the recovery column, the fourth to supply the compressed second steam from the collector to the remote boiler of the distillation column, fifth to supply the compressed second steam from the collector for boiling.

Obtaining a condensed vinasse of increased feed value is achieved by installing a rotary compressor on the line of a secondary steam and reducing the pressure and temperature of evaporation of the vinasse vinasse in the evaporation apparatus, which reduces the denaturation of proteins, fats and carbohydrates contained in vinasse.

Resource saving is achieved by reducing the consumption of heating steam from the boiler room and using instead of it part of the compressed secondary steam for heating the distillation column and for boiling.

Thus, the set of essential features set forth in the formula of the utility model, allows to achieve the desired technical result.

The inventive resource-saving installation of continuous operation for obtaining rectified ethyl alcohol, grains and condensed vinasse from the mash is working as follows.

The mash through the mash heater 4 is fed to the upper plate of the mash column 1 operating under vacuum heated by the secondary steam of the evaporator 20. The vapors are condensed in the mash column condenser (mash heater) 4. The separator 9, irrigated with hydroselective water, is equipped with a lower side fitting 10 for input carbon dioxide, the upper side fitting 12 for introducing hydroselective water, the lower fitting 11 for draining water into the annulus of the condenser, and the upper fitting 13 for removing carbon dioxide to the vacuum pump 14. Steam Enriched with ethanol, aldehydes, esters, higher alcohols, acids, CO ₂ and other alcohol impurities enter the mash heater 4, where they are mixed with hydroselective water entering through the upper side fitting 12 and condense. The resulting mixture of hydroselective water with distilled distillate enters the nutrient plate of the emulsion column 2, heated by the secondary vapor of the evaporator 20. Upon leaving the emulsion column 2 pairs containing volatile impurities passing through reflux condenser 5 and condenser 7, consisting of esters, aldehydes, methanol and soluble in them volatile substances, in the form of an etheroaldehyde fraction (EAF) are removed from the unit to the EAF collection. The epurate, freed from the bulk of the head impurities, is fed to the nutrient plate of the alcohol column 3, heated by the secondary steam of the evaporator 20. Unpasteurized alcohol, having passed through the reflux condenser 6, is taken from the condenser 8 of the alcohol column 3, recycled to the upper plate of the epilation column 2. Fusel alcohol, taken from the plates above the nutritious, and fusel oil, taken from the plates below the nutritious, are removed from the installation. Rectified alcohol is taken from the upper plates of the alcohol column 3. The forced circulation of the stillage through the thermosiphon boiler 15 is carried out by the pump 19. Its balance excess is fed to the decanter 18, where it is separated into sediment (pellet) and the stillage filtrate discharged into the evaporator 20, heated by heating steam. Secondary steam enters the rotary compressor 21, where it is compressed to a higher pressure. Compressed steam is supplied to the manifold 22, equipped with five fittings: the first fitting 23 for supplying a compressed second pair to the collector, the second 24 for supplying a compressed second pair from the collector to the remote reboiler of the washing column, the third 25 - for supplying the compressed second pair from the collector to the remote boiler of the distillation column, fourth 26 - for supplying compressed second steam from the collector to the remote boiler of distillation column, fifth 27 - for supplying compressed second steam from the collector for boiling. Valves 28, 29, 30, 31 are used to control the flow rate of compressed secondary steam. Condensed bard is removed from the evaporator 20 for further processing.
