Abstract
The utility model relates to a biological reaction device of the inorganic membrane, which comprises a fermentation tank, a micro-filtration membrane separator and an ethanol permeation membrane separator, communicating with each other by pipes, and both of the two membrane separators comprise a membrane tube and a jacket. The device couples the membrane-separating technology with the biological reaction technology, and continuously conveys the fermentation liquid containing the ethanol in the fermentation tank by a pump; the fermentation liquid is separated twice by a micro-filtration membrane and an ethanol permeation membrane; the ethanol in the permeate liquid is concentrated to 40-99.5 wt percent and then can be an ethanol product or be refined further, while the unpermeated fermentation liquid returns to the fermentation tank from the outlet of the membrane tube for further reaction. The device realizes the reduction of the feedback inhibitory effect of the ethanol on reaction by continuously separating and removing the reaction product-the ethanol, thus increasing the conversion rate of the ethanol and reducing the energy consumption. The inorganic membrane adopts a ceramic tube as a supporter, the ethanol permeation membrane adopts a MFI inorganic molecular sieve membrane, and the micro-filtration membrane adopts an inorganic ceramic membrane.
Description
(technical field)
The utility model relates to a kind of biological fermentation and produces alcoholic acid mineral membrane biological reaction apparatus.
(background technology)
In biological fermentation system ethanol process,, can produce feedback inhibition to fermenting process along with the increase of fermentation cylinder for fermentation product alcohol concn, enzymic activity is weakened, the biological fermentation ability reduces, thereby has directly influenced the yield of conversion of raw material and product, so throughput is lower.For keeping higher ethanol conversion and conversion rate, need constantly to separate the ethanol of removing in the fermented liquid, but present alcohol production device can't be realized this process mostly continuously, production efficiency is low, the energy consumption height.
(summary of the invention)
The purpose of this utility model provides a kind of mineral membrane bio-reactor, and it can separate continuously and removes the ethanol that generates in the fermented liquid, reduces the feedback inhibition of end product ethanol to the reaction of biology, improves the throughput rate of biological respinse, cuts down the consumption of energy.
The utility model mineral membrane biological reaction apparatus contains fermentor tank, microfiltration membrane separator, well heater and alcohol permselective membrane separator, and therebetween with pipeline connection, microfiltration membrane separator and alcohol permselective membrane separator all comprise film pipe and chuck; One side of alcohol permselective membrane film pipe scribbles mineral membrane; The outlet pipe of fermentor tank is by the film pipe import of feed pump feeding microfiltration membrane separator, the import of the logical fermentor tank of the exit end of this film pipe; The Jacket outlet of microfiltration membrane separator is led to film pipe entrance end into the alcohol permselective membrane separator by the feed pump heater via, and the film pipe exit end of alcohol permselective membrane communicates with fermentor tank; The chuck of alcohol permselective membrane separator is provided with the ethanol output tube; The chuck of microfiltration membrane separator and alcohol permselective membrane separator is connected to vacuum pump respectively.
The film of microfiltration membrane separator is the inorganic ceramic microfiltration membrane, and the aperture is at 0.1-1 μ m.The film pipe of alcohol permselective membrane separator scribbles MFI type molecular screen membrane.
Preheater is equipped with in the import of fermentor tank, and the film pipe exit end of alcohol permselective membrane separator returns fermentor tank after by the preheater heat release.
A kind of new bio reaction unit that this device is coupled to form mineral membrane separator and biological fermentation tank, it can be extracted out continuously with containing the alcoholic acid fermented liquid, tentatively permeate by microfiltration membrane earlier, behind the reheat by the alcohol permselective membrane infiltration evaporation, make ethanol wherein from fermented liquid, separate enrichment, and the fermented liquid that does not see through constantly return fermentor tank continuation participation biochemical reaction (i.e. fermentation) from the outlet of film pipe.
In sum, the utility model device is under the power of pump, the interior fermented liquid of fermentor tank is constantly extracted out, utilize the separation performance of mineral membrane selective permeation, isolate ethanol wherein, return fermentor tank and will not contain the alcoholic acid fermented liquid, fermented liquid is in continuous round-robin process, the ethanol that generates in the fermentor tank separated continuously shift out, and ethanol is concentrated to about 40-99.5wt%.Thereby reduced the feedback inhibition effect of ethanol to biological fermentation, fermenting process is carried out continuously, improves transformation efficiency, has reduced energy consumption.
(description of drawings)
Accompanying drawing is the synoptic diagram of the utility model mineral membrane biological reaction apparatus.
1 is fermentor tank among the figure; The 3rd, microfiltration membrane separator, device contain a plurality of film pipes 32 that outer wall scribbles microfiltration membrane, and the film pipe is outward a chuck 31; The 5th, alcohol permselective membrane separator, device contain a plurality of film pipes 52 that outer wall scribbles MFI type molecular screen membrane, and the film pipe is outward a chuck 31.
As shown in the figure, the fresh culture agent adds in the fermentor tank 1 by material inlet pipe 8 through preheater 7 continuously, the outlet of fermentor tank will contain alcoholic acid fermented liquid material by pump 2 to be sent in the chuck 31 of microfiltration membrane separator 3, the lower end enters in the film pipe, under the suction of vacuum pump 6, ethanol in the material and a part of fermented liquid see through microfiltration membrane and enter in the pipe of film pipe 32, subsequently by pump 2 ' send into well heater 4, go into the chuck 51 of alcohol permselective membrane 5 after the intensification, vacuum pump 6 ' suction under, ethanol in the material sees through molecular screen membrane and enters in the pipe of film pipe 52, and from the outlet of pipe by valve 8 " continuously outflow, collect as alcohol product or send to further make with extra care the dehydrated alcohol product.The outlet effusive liquid that do not see through in microfiltration membrane chuck 31 upper ends is integrated with material inlet pipe 8, returns in the fermentor tank 1.The outlet of the upper end of alcohol permselective membrane chuck 51 is effusive to be seen through liquid and returns in the fermentor tank 1 by after preheater 7 and the stock liquid heat exchange from valve 8.Above-mentioned fermented liquid is constantly extracted out and is returned, continuously circulation.
In the utility model, the film pipe is supporter with the vitrified pipe, and the membrane pore size of microfiltration membrane pipe 32 is at 0.1-1 μ m; Alcohol permselective membrane pipe 52 scribbles MFI type organic zeolite membrane at the outer wall of vitrified pipe.
