Abstract
The utility model discloses a carbon dioxide recycling gas stripping fermentation device which consists of a seed fermentation tank, a main fermentation tank, a carbon dioxide washing tower, a compressor and a later-stage fermentation tank, wherein CO2 discharged by the seed fermentation tank and the main fermentation tank enters the washing tower through a gas inlet A at the bottom of the washing tower; after cooling and alcohol removal by the washing tower, CO2 enters the compressor through a gas outlet on the upper part of the washing tower for pressurization; pressurized CO2 enters from a gas inlet at the bottom of the later-stage fermentation tank, and goes through a gas outlet on the top of the later-stage fermentation tank and enters the washing tower through a gas inlet B at the bottom of the washing tower so as to wash out alcohol in the gas; washed CO2 gas enters a CO2 workshop through a gas outlet on the top of the washing tower for recycling; and the mixed liquid of alcohol and water enters a material pool through a mixed liquid outlet at the bottom of the washing tower for back steaming. The device disclosed by the utility model has the beneficial effects that partial alcohol and heat are carried away in the carbon dioxide gas stripping process so as to reduce the damage of alcohol in the fermentation liquid on yeast and the burden on a spiral plate heat exchanger; and CO2 purity is improved by the recycling of carbon dioxide, and the utilization rate of CO2 is increased.
Description
Technical field
The utility model relates to a kind of device of carbon dioxide recycling gas stripping fermentation.
Background technology
the fermentation mode that present industrial production alcohol adopts is that fermentor tank is divided into seeding tank, main fermentation tank and fermentation later stage tank, after feed liquid is lowered the temperature by the heat exchange of saccharification spiral-plate heat exchanger, get in seeding tank and mix with yeast, and then be pressed onto and carry out lord ferment period fermentation in main fermentation tank, be pressed into respectively again the later stage fermentation tank by main fermentation tank at last and carry out later stage fermentation, in whole fermenting process, the lord ferment period nutrient is sufficient, ethanol content is lower, yeast activity is vigorous, the alcohol that this stage produces accounts for 80% of whole fermenting process, most carbonic acid gas is also to produce this period, the fermentation later stage is along with nutriment, increasing of the reduction of oxygen content and ethanol content, vigor and the liquor-producing ability of yeast have been affected, bad if ferment, it is high that the yeast mortality ratio will appear, residual sugar in ripe wine with dregs is crossed the problems such as high, cause starch utilization ratio low, cause wastage of material, for avoiding the problems referred to above, the temperature control homogeneous measure of taking at present is with impeller pump, feed liquid to be extracted out by the bottom, through getting to the fermentor tank top after the spiral-plate heat exchanger heat exchange, but still the part that comes with some shortcomings: 1, each tank is equipped with an impeller pump and a spiral-plate heat exchanger, and electricity consumption, water consumption are large, 2, can only play the homogenization of part, be difficult to make whole tank fully to homogenize, yeast mixes uneven with mash, and in tank, temperature is uneven, causes that finally ripe wine with dregs residual sugar is too high, 3, can't reduce wine degree in karusen, the liquor-producing ability of yeast still is suppressed.
Summary of the invention
The purpose of this utility model is to provide a kind of device of carbon dioxide recycling gas stripping fermentation.
The utility model is to address the above problem the technical scheme of taking to be: a kind of device of carbon dioxide recycling gas stripping fermentation, formed by seed fermentation tank, main fermentation tank, carbonic acid gas water wash column, compressor, later stage fermentation tank, it is characterized in that: bottom described carbonic acid gas water wash column, inlet mouth A, inlet mouth B and mixture export are set, top and top respectively arrange an air outlet; Described seed fermentation tank and main fermentation tank and carbonic acid gas water wash column bottom air inlet A UNICOM, the air outlet on carbonic acid gas water wash column top and compressor UNICOM, compressor and later stage fermentation pot bottom inlet mouth UNICOM, air outlet, later stage fermentation tank top and water wash column bottom air inlet B UNICOM; By the CO that discharges in seed fermentation tank, main fermentation tank
2A enters water wash column by the water wash column bottom air inlet, except after drinking, enters compressor boost through air outlet, water wash column top, the CO after pressurization through the water wash column cooling
2Entered by later stage fermentation pot bottom inlet mouth, air outlet, fermentor tank postmenstruation top enters water wash column from water wash column bottom air inlet B again, the alcohol in eccysis gas, the CO after washing
2Gas enters CO by air outlet, water wash column top
2Recycle in the workshop, and the mixed solution of alcohol and water enters material Chi Huizheng by the mixture export of water wash column bottom.
The beneficial effects of the utility model: (1) carbonic acid gas air lift process is taken away part alcohol, and in fermented liquid, alcohol to saccharomycetic toxic action, makes the yeast cell increased activity thereby reduce, and starch utilization ratio improves; (2) the air lift process is taken away the part heat, has alleviated the load of impeller pump and spiral-plate heat exchanger, can come water-saving, power saving by the aperture that reduces the impeller pump rotating speed or reduce the impeller pump opening times and reduce the spiral plate water coolant; (3) the limited oxygen that obtains from water when the water wash column of carbonic acid gas, can keep yeast activity, extends yeast work-ing life, is beneficial to fermentation; (4) the full and uniform mixing of fermentation liquid guarantees temperature in tank, the unification of mash homogeneous, reduces the blowing time, saves distillation vapour; (5) recycling of carbonic acid gas improved CO
2Purity has increased CO
2Utilization ratio.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Accompanying drawing is the utility model schematic diagram.
In figure: 1 seed fermentation tank, 2 main fermentation tanks, 3 water wash columns, 4 air outlets, water wash column top, 5 air outlet, water wash column tops, 6 air outlets, later stage fermentation tank top, 7 later stage fermentation tanks, 8 compressors, 9 water wash column bottom air inlet B, 10 mixture exports, 11 water wash column bottom air inlet A.
Embodiment
The device of a kind of carbon dioxide recycling gas stripping fermentation as shown in the figure is by the CO of seed fermentation tank 1, main fermentation tank 2 abhisecas discharges
23 bottom air inlet A11 enter water wash column 3 by water wash column, except after drinking, enter compressor 8 superchargings, CO pressurization after through air outlet, water wash column top 5 through water wash column 3 coolings
2Entered by later stage fermentation tank 7 bottom air inlets, fermentor tank postmenstruation 7 air outlets, top 6 enter water wash column 3 from water wash column bottom air inlet B9, the alcohol in eccysis gas, the CO after washing again
2Gas enters CO by air outlet, water wash column top 4
2Recycle in the workshop, and the mixed solution of alcohol and water enters material Chi Huizheng by the mixture export 10 of water wash column bottom.
