Abstract
The invention provides a fermentation liquor recycling process and device. The device mainly comprises a fermentation tank, a cyclone separator, a recycle tank and an s-shaped curved pipe, wherein the cyclone separator is arranged at the upper part of the fermentation tank; the s-shaped curved pipe is arranged at a gas pipeline connected with the cyclone separator; and the lowest point of the s-shaped curved pipe is connected with a liquid pipeline connected with the recycle tank. In the fermentation process, the gas is subjected to secondary and tertiary gas-liquid separation after being subjected to the separation of the cyclone separator, and more escaping liquid can be collected, without generating bubbles caused by overmuch gas in the collecting process, so as to reduce the size of the recycle tank.
Description
Technical field
The invention belongs to field of fermentation engineering, specifically relate to the fermented liquid that a kind of s bend pipe replaces straight tube to be applied on the fermentor tank and recycle technique and device.
Background technology
Biochemical reactor is the biological technical field of multidisciplinary intersection, is one of important front edge of 21 century biotechnology development.Biochemical reactor is the nucleus equipment that carries out biochemical reaction, and its structure, operating method and operational condition have close relationship to the transformation efficiency of reaction raw materials and the quality of product.Development so far, biochemical reactor has formed broad variety: on the structure of reactor feature, developed at present the types such as autoclave, pot type, tubular type, tower, pattern.Can be divided on operating method that stream adds formula, batch-type, stream adds formula in batches.Simultaneously in the process of producing, people also can be by constantly improving or optimizing equipment, so that maximum production, environment optimization, simplifying of personnel, the energy minimize.
During glutamic acid fermentation enterprise produced, the fermentor tank gas-liquid separation was not thorough, can cause entrained liquids discharge in the gas yet, caused the wasting of resources, environmental pollution.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of fermented liquid and recycle technique and device.
Technical scheme of the present invention is as follows:
A kind of fermented liquid is recycled technique, and the gas of escaping liquid from carrying secretly of discharging of fermentor tank hits separator and carries out the gas-liquid initial gross separation through revolving; After initial gross separation, carry the gas of escaping liquid secretly and carry out 1-4 gas-liquid separation through the s bend pipe again; Gas is discharged by pipeline, and liquids recovery is to the withdrawing can utilization.
The present invention also provides a kind of fermented liquid recycle device, it mainly comprises fermentor tank, revolves and hit separator, withdrawing can and s bend pipe, revolve and hit the top that separator is located at fermentor tank, hit the gas pipeline that separator links to each other and be provided with the s bend pipe with revolving, lower-most point at the s bend pipe connects fluid pipeline, and fluid pipeline is connected with withdrawing can.
Described fermented liquid recycle device, preferred scheme is that the fermentor tank volume is 300-800m
3(preferred 500m
3).
Described fermented liquid recycle device, preferred scheme are that the s bend pipe is located at distance and revolves the 50-180cm place (preferred 100cm place) of hitting separator.
Described fermented liquid recycle device, preferred scheme is that the quantity of s bend pipe is 1-4 section (being preferably 2 sections).
Described fermented liquid recycle device, preferred scheme be, the quantity of s bend pipe is not just 1 section the time, intermittent arrangement between each section, the centre is the preferred 120cm of 50-200cm() straight tube.
Described fermented liquid recycle device, preferred scheme is that withdrawing can, s bend pipe, gas pipeline and fluid pipeline are stainless steel.
During glutamic acid fermentation enterprise produces, for save energy, environmental contamination reduction, can exhaust position install to revolve at fermentor tank and hit separator and be used for gas-liquid separation, reduce and escape liquid.But this way can be escaped liquid fully, reclaims the liquid that waste gas is carried secretly so can be connected to withdrawing can at gas exhaust duct.Its recovery channel adopts straight tube.And the employing straight tube can not make gas-liquid well separate, and the gas of carrying secretly in the recovery liquid causes to reclaim in the liquid and contains a large amount of foams, and its volume is increased, and then the withdrawing can volume that needs increase, causes the facility investment increase.And gas-liquid separation is not thorough, can cause entrained liquids discharge in the gas yet, causes the wasting of resources, environmental pollution.The invention enables in the fermenting process gas after the separation of hitting separator through overwinding, to pass through again for the second time and for the third time gas-liquid separation, make and escape liquid and can more be collected, but in collection process, avoided again carrying too much gas secretly and produced foam, thereby reduced the volume of withdrawing can.
Escape liquid by method of the present invention and device recovery, Duo more than 40% than straight tube.And gas-liquid separation is thorough, reclaims in the liquid and carries seldom liquid secretly, and the withdrawing can volume reduces 3-5 doubly.The invention has the advantages that, facility investment is few, escape the liquid gas-liquid separation thoroughly, the withdrawing can volume is little, environmental pollution is little.
The invention discloses the application of a kind of s bend pipe on the glutamic acid fermentation tank, specifically in L-glutamic acid (Methionin) fermentative production, gas exhaust duct can be carried the part fermented liquid secretly, uses the s bend pipe at the pipeline that reclaims this fermented liquid.Reclaimed on the straight pipeline of this fermented liquid with the past and to compare, have gas-liquid separation thoroughly, the advantage such as the withdrawing can volume is little, facility investment is few, environmental pollution is little.Has good application value in industries such as fermentation, chemical industry.
