Abstract
The utility model discloses a recovery device of fermentation liquid spilled from a fermentation tank for citric acid production, which comprises the fermentation tank (1), an exhaust pipe (3) and a fermentation liquid return pipe (2). The inlet end of the fermentation liquid return pipe (2) is fixed at the bottom of a recovery tank (4). A spiral separation tube installation case (7) is arranged at the upper portion of the recovery tank (4), a spiral separation tube (8) are fixed inside the spiral separation tube installation case (7), and an upper port of one of the spiral separation tube (8) is connected with the outlet end of the exhaust pipe (3). A lower port of one of the spiral separation tube (8) is arranged on the upper portion inside a cavity of the recovery tank (4). A discharge pipe (9) is arranged above the recovery tank (4). The recovery device of the fermentation liquid spilled from the fermentation tank for the citric acid production is simple in structure, convenient to use, long in service life and high in separation efficiency, can enable the pressure inside the fermentation tank to be constant, and greatly reduces bacteria infection probability of the fermentation liquid.
Description
Technical field
The utility model relates to the equipment that a kind of citric acid production is used, the fermented liquid retrieving arrangement that a kind of specifically citric acid production is overflowed with fermentor tank.
Background technology
In the production of present citric acid; in carrying out fermentation process; particularly in the aerobic microbiological fermenting process; because the respiration of aerobic microbiological and the influence of oxygen supply pressure size; making fermented liquid that " escaping material " take place through regular meeting in exhaust system, had both caused the waste of fermented liquid, and had reduced output, increased production cost; and cause the probability of microbiological contamination to increase, bring very big influence to production.In order to reduce this influence, what adopt at present is that common cyclonic separator reclaims, but because this common cyclonic separator separating effect is low, unreasonable structure, still often the problem of escaping to expect, have in addition cause whole fermentor tank microbiological contamination, have to carry out the branch jar again and disinfect, cause the whole production cost to rise, influence carrying out continuously of whole production.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, be convenient to the maintenance, low price, long service life, the fermented liquid retrieving arrangement that the citric acid production that Separation and Recovery efficient is high is overflowed with fermentor tank.
In order to reach above purpose, the technical scheme that the utility model adopted is: the fermented liquid retrieving arrangement that this citric acid production is overflowed with fermentor tank, comprise fermentor tank, vapor pipe and fermented liquid return line, vapor pipe is located at the top of fermentor tank, the fermented liquid return line is located at the middle part of fermentor tank, it is characterized in that: the entrance end of fermented liquid return line is fixed on the bottom of withdrawing can, be provided with spiral separation pipe install bin on the top of withdrawing can, spiral separation pipe on spiral separation pipe install bin internal fixing, the upper port of spiral separation pipe is connected with the exit end of vapor pipe, the lower port of spiral separation pipe is located at withdrawing can chamber internal upper part, is provided with delivery pipe on the top of withdrawing can.
The utility model is also implemented by following measure: the chamber inner bottom part of described withdrawing can is provided with stabilier, and the center of stabilier is provided with through hole.
The beneficial effects of the utility model are: simple in structure, easy to use, long service life, and the separation efficiency height can keep constant pressure in the fermentor tank, and fermented liquid microbiological contamination probability reduces greatly.
Description of drawings
Fig. 1 is a structure partial cross-sectional schematic of the present utility model.
Among the figure: 1, fermentor tank; 2, fermented liquid return line; 3, vapor pipe; 4, withdrawing can; 5, stabilier; 6, through hole; 7, spiral separation pipe install bin; 8, spiral separation pipe; 9, delivery pipe.
Embodiment
Make the utility model with reference to accompanying drawing 1.The fermented liquid retrieving arrangement that this citric acid production is overflowed with fermentor tank, comprise fermentor tank 1, vapor pipe 3 and fermented liquid return line 2, vapor pipe 3 is located at the top of fermentor tank 1, fermented liquid return line 2 is located at the middle part of fermentor tank 1, it is characterized in that: the entrance end of fermented liquid return line 2 is fixed on the bottom of withdrawing can 4, be provided with spiral separation pipe install bin 7 on the top of withdrawing can 4, spiral separation pipe 8 on spiral separation pipe install bin 7 internal fixing, the upper port of spiral separation pipe 8 is connected with the exit end of vapor pipe 3, the lower port of spiral separation pipe 8 is located at withdrawing can 4 chamber internal upper parts, like this when the material of fermentor tank 1 produces the gas discharge, the mixture of fermented liquid and gas enters spiral separation pipe 8 from vapor pipe 3, in spiral separation pipe 8, produce centrifugation, it is spouting to be tangential direction from lower port at last, enters in the withdrawing can 4 fermented liquid and gas delivery, be provided with delivery pipe 9 on the top of withdrawing can 4, gas can be discharged from delivery pipe 9.
The chamber inner bottom part of described withdrawing can 4 is provided with stabilier 5, the center of stabilier 5 is provided with through hole 6, and fermented liquid can flow into fermented liquid return line 2 in through hole 6 after assembling on the stabilier 5 like this, flow at last in the fermentor tank 1, stabilier 5 can be made by stainless steel plate.
Fermented liquid in the fermentor tank exhaust system can be carried out Separation and Recovery by the utility model, isolating fermented liquid reenters in the fermentor tank, isolating fermentation gas then enters in the exhaust system, guaranteed the constant of pressure in the fermentor tank, guaranteed the eupnea of microbial fermentation, simultaneously also guaranteed to cause the probability of fermented liquid microbiological contamination, thoroughly solved fermented liquid and " escaped to expect " problem that problem and fermented liquid microbiological contamination probability increase because of former retrieving arrangement pressure instability.
Claims (2)
