Abstract
The utility model relates to a bio-fermentation device, and particularly provides a circular spray-type aerobic fermentation device structurally comprising an air distribution pipe with an air inlet pipe. The circular spray-type aerobic fermentation device is characterized in that a plurality of jet mixing mechanisms are in plug-in connection with the air distribution pipe; each jet mixing mechanism comprises an air jet pipe, a reducing suction chamber and a diffusion pipe; the reducing suction chamber is communicated with the diffusion pipe; the air jet pipe communicated with the air distribution pipe is arranged on the central lines of the reducing suction chamber and the diffusion pipe; and suction holes are formed on the side walls of the reducing suction chambers. Compared with the prior art, the utility model has the characteristics of high efficiency, energy conservation and the like.
Description
Technical field
The utility model relates to a kind of biological fermentation device, and a kind of ring spray aerobic fermentation device specifically is provided.
Background technology
Antibiotic fermentation is the biochemical reaction process of a complicacy; Wherein ventilating and stirring is two important parameters in the whole fermentation process; It not only has influence on dissolved oxygen level, and has influence on the form of the mass transfer and the thalline of fermentation system, finally will have influence on the microbial metabolism level.Because antibiotic thallus is the aerobic mikrobe, in its thalli growth growth and biosynthetic process, need oxygen, thalline is looked more vigorous, and the requirement of oxygen is just bigger, but oxygen is insoluble in water.Oxygen is the poor of oxygen concn in saturated oxygen concentration and the fermented liquid by the total impellent of gas phase diffusion to cell interior, and main resistance is liquid-film resistance, therefore, if will improve the transmission effect of oxygen, will improve power of agitator and increase air flow.Yet any breather that current traditional general form fermentor tank is adopted, its bubble diameter increases along with the increase of air flow, and bobble rise velocity also increases thereupon; The bubble degree of grinding does not but increase along with the increase of mixing speed, and it can only maintain on the same order of magnitude.Therefore, increasing air flow not only can not have raising by a relatively large margin with the increase power of agitator to volumetric mass transfer coefficient, will cause the consumption of mass energy and the raising of product cost on the contrary.
Summary of the invention
The utility model is the deficiency to above-mentioned prior art, and a kind of efficient, energy-conservation ring spray aerobic fermentation device is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of ring spray aerobic fermentation device; Comprise the air distribution pipe that is provided with inlet pipe, be characterized in, be plugged with some jet mixed organizations on the air distribution pipe; Said jet mixed organization comprises the airstream pipe; And the convergent suction chamber and the diffuser tube that are interconnected, the airstream pipe that is connected with the air distribution pipe is arranged on the medullary ray of convergent suction chamber and diffuser tube, has suction port on the convergent suction chamber sidewall.
Said convergent suction chamber is connected through trunnion with diffuser tube, and the airstream pipe is arranged on the medullary ray of convergent suction chamber and trunnion.
Said jet mixed organization is located at planar the same side, air distribution pipe place.
The ring spray aerobic fermentation device of the utility model is compared the main jet mixed organization that increased with prior art; Mainly utilize compressed-air actuated original kinetic energy; Penetrate the negative pressure that is produced at a high speed and entrainment effect through the airstream pipe, the nutrient solution in the fermentor tank is sucked and gets in the lump in the jet mixed organization with air, because the swollen expansion effect of air-flow; Fermented liquid acutely mixes with gas; Make fermented liquid and air be ground into a large amount of small grain crowds, bring up the emulsification interface that the turbulence of a height, expansion and surface are brought in constant renewal between gas-liquid, reach the emulsive effect.The jet mixing machine constitutes geometricprogression ground and has enlarged the solution-air contact area, has prolonged the time that gas is overflowed in liquid, has improved the mass transfer effect of dissolved oxygen greatly.Compared with prior art, feed a spot of air and also can fully satisfy the demand of aerobic fermentation dissolved oxygen.Simultaneously, because this device has made full use of compressed-air actuated original kinetic energy, required power of agitator also reduces greatly.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model ring spray aerobic fermentation device;
Accompanying drawing 2 is structural representations of jet mixed organization in the ring spray aerobic fermentation device shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification to the utility model.
Provide a most preferred embodiment below:
A kind of ring spray aerobic fermentation device, its structure mainly is made up of air distribution pipe 1 and jet mixed organization 2.
Air distribution pipe 1 is the annular body.On air distribution pipe 1, be provided with inlet pipe 3.Eight jet mixed organizations 2 equidistantly are arranged in the homonymy of air distribution pipe 1.
Said jet mixed organization 2 is made up of airstream pipe 21, convergent suction chamber 22, diffuser tube 23 and trunnion 24.The coaxial successively connection of convergent suction chamber 22, trunnion 24 and diffuser tube 23.The airstream pipe 21 that is connected with air distribution pipe 1 is located on the medullary ray of convergent suction chamber 22 and trunnion 24.On the sidewall of convergent suction chamber 22, have suction port 25.
During use, the ring of the utility model spray aerobic fermentation device is fixed in the fermentor tank, and inlet pipe 3 is connected with the compressed air delivery device in the external world gets final product.
Above-described embodiment, the utility model embodiment a kind of more preferably just, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
Claims (3)
1. a ring sprays the aerobic fermentation device; Comprise the air distribution pipe that is provided with inlet pipe, it is characterized in that, be plugged with some jet mixed organizations on the air distribution pipe; Said jet mixed organization comprises the airstream pipe; And the convergent suction chamber and the diffuser tube that are interconnected, the airstream pipe that is connected with the air distribution pipe is arranged on the medullary ray of convergent suction chamber and diffuser tube, has suction port on the convergent suction chamber sidewall.
