Abstract
Reutilization of alcohol and grain effluent is carried out by passing grain effluent to solid-liquid separator by distilling tower, entering the separated effluent into grain effluent neutralizer, delivering the neutralized grain effluent into efficient grain effluent deposition tank by transfer pump, entering deposited supernatant into pre-process to produce alcohol by transfer pump, separating out grain as feed by solid-liquid separator and delivering deposit into anaerobic jar to produce marsh gas. The equipments consist of solid-liquid separator, grain effluent neutralizer, efficient grain effluent deposition tank and transfer pump. It's simple, cheap, fast, has no environmental pollution and saves energy resources.
Description
Technical field
Waste liquid and distillers ' grains from alcohol production reutilization technology of the present invention relates to the Technology that distillery waste water is handled, and particularly a kind of waste liquid and distillers ' grains from alcohol production is handled reuse technology.
Background technology
Alcohol industry is an important industry in the national economic development.Can produce a large amount of vinasse waste liquids in the process of producing alcohol, this waste liquid is typical high concentrated organic wastewater.At present, the enterprise of domestic many production alcohol has all adopted the treatment process of anaerobism, oxygen consumption to the vinasse waste liquid, though this technology has produced available biogas energy, realize that the difficulty of discharged wastewater met the national standard is still bigger, general investment cost and running cost are all very high.Disclosed 91103002.6 " process for treating waste liquor of distiller's grain of alcohol " of Chinese patent, adopted the vinasse waste liquid after the neutralization has been carried out disposable solid-liquid separation, owing to be subjected to the restriction of separation machinery performance and separating effect, often higher through the solid content in the vinasse waste liquid after first the separation, if directly be used as the water that feeds intake of Alcohol Production, can not meet the requirement of target water.Disclosed 92107582.0 " no effluent discharging process for secondary distillers ' grains separation " of another Chinese patent, though this technology has overcome the bad problem of above-mentioned process using flash liberation vinasse waste liquid effect, but it is longer that this technology also exists the batch filter filtration time that the second time, separation was adopted, liquid being filtered is subjected to the pollution of assorted bacterium easily, liquid as inciting somebody to action carries out reuse, and is also unfavorable to the yield of liquor and the quality of Alcohol Production.This shows, because above-mentioned two technologies exist the difficult operability of technology and equipment, so there is not an enterprise can effectively realize this technology so far.
Summary of the invention
The purpose of this invention is to provide a kind of waste liquid and distillers ' grains from alcohol production reutilization technology, to solve the insufficient problem of prior art.
The technical solution adopted in the present invention is: be made up of solid-liquid separating machine, distillery waste water neutralising arrangement, the efficient setting tank of grains waste water, transferpump etc.; It is characterized in that: by the grains waste water process solid-liquid separating machine of distillation tower discharge, the waste water of separating enters the distillery waste water neutralising arrangement, send into the efficient setting tank of grains waste water through the neutral grains waste water by transferpump, send into the former process of producing alcohol through the supernatant liquor of post precipitation by transferpump and utilize again; Make feed through the isolated vinasse of solid-liquid separating machine; Send into anaerobic jar through the throw out of the efficient setting tank post precipitation of grains waste water and produce biogas.
Above-mentioned process neutral grains waste water pH value is between 6.8 to 7.0.
Above-mentioned supernatant liquor through post precipitation needs to use up in 4 hours.
According to the size of Alcohol Production scale, above-mentioned solid-liquid separating machine, distillery waste water neutralising arrangement, the efficient setting tank of grains waste water can be separate unit or many uses.
The invention has the beneficial effects as follows: technology is simple, running cost is low, reduced investment, little, the last detective of floor space.Not only reduce source of pollution significantly, and saved the water resources and the energy, can effectively reduce the pollution treatment cost of the Alcohol Production enterprise of different scales, different material.
Description of drawings
Fig. 1 is the technology pie graph of the embodiment of the invention.
Embodiment
Referring to accompanying drawing, the present invention is for producing the embodiment of 10,000 tons of alcohol scales per year: mainly be made up of 3,4 transferpumps 4 of 3 efficient setting tanks of 2,4 useless groove water of 1,1 distillery waste water neutralising arrangement of the continuous separating machine of grains waste water etc.; It is characterized in that: by its temperature of grains waste water continuous separating machine 1 of process grains waste water about 85 degree of distillation tower discharge, the waste water of separating enters distillery waste water neutralising arrangement 2, through neutral grains waste water pH value is 6.8 to 7.0 to send into the efficient setting tank 3 of grains waste water by transferpump 4, sends into the former process of producing alcohol by transferpump 4 through the supernatant liquor of post precipitation in less than 4 hour time and utilizes; Make feed through the continuous separating machine 1 isolated vinasse of grains waste water; Send into anaerobic jar through the throw out of efficient setting tank 3 post precipitations of grains waste water and produce biogas.
The supernatant liquor that utilizes again after the above-mentioned processing can not influence the yield of liquor and the quality of Alcohol Production.
Above-mentioned isolated lees feeds is worth unaffected.
Above-mentioned throw out is sent into anaerobic jar can improve product biogas efficient.
