Abstract
A flocculating and air floating process for treating the liquid from alcohol vinasse includes such technological steps as addition of iron trichloride (300-500 PPM) and sodium hydroxide (300-500 PPM), mixing, passing the mixture in air-dissolving tank, delivering it through pipeline releaser, addition of sodium polyacrylate (30-100 PPM) by pipeline jetter, passing it into air floating pool, solid-liquid separation, collecting floated dregs which is delivered into DDG processing system and then baked to obtain feed, and reusing the clean liquid as raw water. Its advantages include simple and feasible process, saving energy, less investment and reuse of all materials.
Description
The present invention relates to the poor liquid of Spirit industry and handle, more specifically relate to a kind of method for the treatment of alcohol distiller's solution by flocculation and vapour float.
The poor liquid of China's Alcohol Production year discharging is 6,000 ten thousand tons at present, the BOD28000 to 35000mg/L of poor liquid, COD35000 to 45000mg/L.Total amount of organic is 300 to 4,000,000 tons in the annual discharging alcohol, not only wastes resource, and causes the severe contamination to ecological environment, also directly influences the development of alcohol industry.Distiller's dried grain has good feeding value, and distiller's dried grain is with three kinds: a kind of is vinasse solid content (DDG); Extract (DDS) in the another kind of distillage filtrate; Another is preceding two kinds mixture (DDGS), and certain feeding value is all arranged.What study successful vinasse clear filtrate fully recovering technology in the world the earliest is German Krupp, the said firm sells technology the C-E-Lnmmus company of the U.S., go into operation, this technology is decided to be " LBW " technology, its technological process is: corn is as raw material, and------------fermentation---is distilled---vinasse---centrifugation---wet slag---extrusion dehydration---drying to dipping in saccharification in liquefaction (the Bai Ladong machine of stopping) in removal of impurities.This process characteristic is: 1, the maximum processing temperature of raw material has only 95 ℃, thus the toxic action of the harmful substances such as melanoid that generate because of amino sugar reaction (stepping Maillard reaction) can avoid pressure cooking the time; 2, the vinasse Separation of Solid and Liquid will adopt horizontal decanter centrifuge, and the solid content in the filtrate is lower, belongs to clear filtrate, and this is favourable to reuse, but power consumption is than higher; 3, corn is 90-95 ℃ of immersion, and gelatinization liquefaction replaces while pulverizing to add a one amylase, and saccharifying also carries out under the situation of mechanical lapping, and saccharificatinn period is very short, is beneficial to the carrying out of saccharifying afterwards; 4, all disintegrating apparatus of this technology are the Bai Ladong machines of stopping, and these facility have pulverizing, homogenization, also have the convey materials effect, and the drive motors of this machine is 300KW; 5, distiller's yeast adopts German thermotolerant yeast, and normal fermentation temperature is 37-40 ℃, and 150M is arranged
33 of pre-fermentation tanks, 1100M
39 of main fermentation tanks, 1100M
31 in storage wine with dregs jar, the open-air installation, the shared platen formula heat exchanger of per 3 fermentation tanks, no cooling worm in jar cleans and carries out automatically, but without steam sterilization; 6, four tower differential pressure energy-saving process are adopted in distillation, and producing product is the fuel absolute alcohol; 7, vinasse carry out Separation of Solid and Liquid through sedimentation-type centrifuge, obtain loose DDG feed then, and clear filtrate is to fully recovering.This technology is a kind of fine vinasse comprehensive utilization process, the import but equipment such as the Bai Ladong machine of stopping are still needed, and whole technology investment is big, only is that the big factory of raw material can consider to adopt with the corn.Current, most of plant produced DDG of China or DDGS, its technological process is: vinasse, and---------drying---granulation---packing, wherein evaporation section is six grades of evaporimeters to evaporation and concentration, invests near 2,000,000 yuan, and steam need be provided in centrifugation.
The method that the purpose of this invention is to provide a kind for the treatment of alcohol distiller's solution by flocculation and vapour float is carried out Separation of Solid and Liquid with vapour is floating, invests for a short time, and energy savings has solved the problem of material fully recovering simultaneously.
For reaching above-mentioned purpose, the present invention is by the following technical solutions: isolated poor liquid is with being pumped into the floating pond of vapour from vinasse, dosing drops into ferric trichloride 300-500PPM and NaOH 300-500PPM before adopting pump, mix after pass through the pipeline release behind the dissolving, the pipeline ejector enters the floating pond of vapour after adding Sodium Polyacrylate (amide containing 10%) 30-100PPM, carry out Separation of Solid and Liquid, the scum silica frost that scrapes then (DDS) is got back to the DDG treatment system, be dried into feed, but following clear liquid is faint yellow fully recovering as the spice water.
The present invention compared with prior art has the following advantages: technology is easy, and is easy to implement the method, invests little, investment is 21% of six grades of evaporations, takes up an area of for a short time, and operating cost is low, does not need steam, can save a large amount of energy, the material fully recovering has society and economic benefit widely.
Embodiment:
Isolated poor liquid is with being pumped into the floating pond of vapour from vinasse, carry out centrifugation then, separate the poor liquid dispensing in back, to insert the dispensing jar after the concentration dissolving of ferric trichloride by 0.5-1.5%, NaOH is inserted another dispensing jar by the concentration of 5-20%, Sodium Polyacrylate is inserted the 3rd dispensing jar by the concentration of 3-8%, medication administration method is: the dosing before pump of ferric trichloride and NaOH, ferric trichloride is pressed the dosage input of 1-3, NaOH reaches 6-9 through poor liquid pH value and is advisable, its color of perusal is little salmon pink, Sodium Polyacrylate drops in the pipeline after the poor liquid of molten gas discharges, drop into Sodium Polyacrylate 3-7%, carry out pipeline release and mixing again, adopt bassoon, make water through inlet, gas, ferric trichloride, NaOH, the liquid that Sodium Polyacrylate mixes has certain polymerization time to give into wadding to spend the back steadily, it is floating to enter the floating pond of vapour vapour lentamente, and the clear liquid after vapour is floating is made spice.Vapour is floating and centrifugation is come out scum silica frost and poor slag, drying becomes feed.
