Description
Technical field
The present invention relates to fields such as alcohol, environmental protection, specifically with the vinasse that produce behind the dense mash fermenting alcohol producing through the disposable solid-liquid separation of membrane filtration technique, and with filtrate all as the nonexpondable technology of the water cycle that feeds intake.
Background technology
Alcohol is a kind of large leavened prod, occupies an important position in national economy.In recent years, because people are to energy shortage and the earth " Greenhouse effect " aggravation, temperature raises, the understanding of the catastrophic effect that causes is deepened with day aligned, add the use that is under an embargo of reason that some gasoline comburants that many gasoline production and supplier advertise in recent years such as methyl tertiary butyl ether (MTBE) etc. are harmful to health because of polluted underground water etc., utilize alcohol partly to substitute gasoline and also become more surging as the cry of liquid fuel and gasoline comburant as bioenergy.The development fuel alcohol not only can consume starch-containing raw materials such as a large amount of corns, promotes the sustainable development of agricultural planting industry; And can be used as the pollution that clean fuel substitutes gasoline or alleviates vehicle exhaust as gasoline dope, protect environment.Simultaneously, also can alleviate the intake pressure of strategic materials crude oil.China formally comes into effect the fuel alcohol plan.Exploitation fuel alcohol subject matter is that the fuel alcohol price is higher than gas price, is open question still in the world.At present, the price of fuel alcohol is higher than about 1200 yuan/ton of gas prices, and how reducing the zymamsis production cost is the focus of research.Simultaneously, fermentation alcohol production can produce big quantity of fluid vinasse, as not handling and utilizing, enter rivers after, bring very serious pollution to environment.At present, the vinasse in the unprocessed discharging of China grain distillery have become the second largest source of pollution of light industry.For this reason, country and each manufacturing enterprise to the improvement of vinasse all very concern and drop into very big manpower and financial resources.
Membrane separation technique is a kind of isolation technique efficiently, and it is by the selective osmosis of film in sepn process, and the component of the different-grain diameter in liquid and solid particulate or the liquid is separated.Research to membrane separation technique starts from the thirties in 20th century, has carried out after the fifties and has goed deep into extensive studies more, makes its acquisition develop and drop into industrial applications rapidly.Its item key is that all kinds synthetic film with practical value occurs one after another.Simultaneously, because it is easy to operate, compact construction, maintenance cost is low, is easy to automatization, is known as one of the most rising technology in the world, becomes the focus of countries in the world research.The every field that it almost penetrates into research and produces all plays the effect of not replacing in fields such as chemical engineering, biotechnology, food, medicine, environmental protection, electronics.At present, the membrane filter plant production of production domesticization is quite ripe, and its quality and import like product are suitable substantially.
Summary of the invention
The objective of the invention is to seek a kind of solid-liquid separation process of concentrated fermented rice liquid, to solve the vinasse pollution problems, passive processing is become initiatively effectively comprehensive utilization, thereby reduce the Alcohol Production cost, the protection environment.
The invention is characterized in the vinasse that to produce behind the dense mash fermenting alcohol producing directly through the disposable solid-liquid separation of membrane filtration technique, and the filtrate fully recovering is used as the water that feeds intake.
The membrane filter plant that the present invention adopts is a ceramic membrane filter equipment, and its operational condition is: pore size filter is 0.2～2 micron, and filtration temperature is 30～98 ℃, and to be good at 60～90 ℃, operating pressure 0.08～0.2 MPa is good with 0.1 MPa especially.
The performance of employed ceramic membrane equipment is: working temperature :-10～110 ℃, and maximum working pressure: 0.8 MPa, pH scope: 1～14.
The present invention is when using filtrate to feed intake water, and pH is advisable with 6.0～6.5, therefore needs to regulate pH.1. the adjusting of pH can be located to carry out in technical process, also can 2. locate to carry out in technical process.When the amount of filtrate does not reach when feeding intake water institute expense, insufficient section is supplied with general water of productive use.
The present invention to the requirement of raw material pulverizing fineness is: more than or equal to 85%, unit is a mass percent by 40 purpose amounts.
The filter residue of the present invention after to solid-liquid separation adopts present conventional treatment method.
All zymamsiss of the present invention all are meant and utilize yeast to carry out zymamsis; Described all zymamsiss all do not comprise solid-state zymamsis.
Alcohol thick mash fermentation of the present invention is meant the described zymamsis technology of patent ZL96117189.8 that adopts, and adopts the described technology of patent ZL96117189.8 to carry out zymamsis with other cereal and the potato starch raw material that the ZL96117189.8 patent does not comprise.Described traditional zymamsis is meant the zymamsis technology that alcohol industry for a long time, generally uses, as water addition ratio more than or equal to 3: 1; Karusen alcoholic strength 8～10%, unit are volume percent; Residual total reducing sugar is smaller or equal to 18 grams per liter karusens.
Thick mash fermentation is because himself, and the vinasse that vinasse and traditional zymotic produced that it produced are different: the vinasse amount that 1 ton of alcohol of 1. every production produces reduces, but through solid-liquid separation rear filtrate fully recovering, there do not have substantially to be unnecessary; 2. solid content increases in the alcohol, adopts vinasse solid-liquid separation effect in the past undesirable; 3. can utilize material to increase in the vinasse, through most of in clear liquid after the solid-liquid separation, therefore reuse water of the present invention is made a world of difference with reuse water in the past, and it can effectively promote fermentation, improves wine degree, fermentation degree.
Zymamsis has inhibiting material to yeast though exist in the vinasse, and membrane filtration can both be taken away a part by wet slag each time.After reuse several times, the concentration of these materials in vinasse can reach running balance, maintains in the scope that yeast can bear, and does not influence zymamsis.
Other soluble material in the vinasse and solid substance also have above-mentioned similar situation, through reaching running balance after the reuse several times.
The invention has the advantages that: can realize the zero release of vinasse substantially, effectively protect environment; Adopt the disposable solid-liquid separation success of membrane filtration technique, changed the shortcoming that in the past needs the multiple tracks separation circuit, reduced facility investment, save cost; Adopt the filtrate recycle technology, significantly reduced water of productive use, save the Alcohol Production cost; Itself contain materials such as remaining starch and carbohydrate, organic acid, vitamin B group and some metabolism intermediates in the filtrate, when reuse, wherein some can be used as fermentation raw material, and some can promote fermentation, finally improves the karusen alcoholic strength.
