Abstract
The utility model discloses a microporous ventilating device for liquid state submerged fermentation. The device comprises a body, a gas generator, a stirrer and a microporous ventilating structure below the stirrer. Bubbles escaped become small, dense and uniform through the design of a microporous air distributor structure and an application of a porous ceramic material. The speed of small bubbles lifting from the bottom end of the device to the liquid level is lower than that of common big bubbles, so that the contact time of gas and liquid is increased. Meanwhile, the stirrer is installed above the microporous air distributor, so that the liquid forms a turbulent flow, and the small bubbles do not rise linearly but spirally, thereby, prolonging the movement time and journey of small bubbles in the liquid. The dissolved amount of oxygen is greatly increased and the ventilating effect is improved, so that the fermenting efficiency is improved.
Description
Technical field
The utility model relates to a kind of breather, especially relates to a kind of liquid submerged fermentation pore type breather.
Background technology
The fermentation unit of manufacturing enterprise's use is generally standard aeration type fermentor tank mostly at present, in aerobic submerged fermentation jar, pressurized air from the sterile air system is injected in the fermentor tank by sparger, sparger has single hole tubular type and porous tubular type, mounting means is different, generally be installed in the below of bottom one grade of agitator, Open Side Down, but the single hole tubular type of this structure or the common bubble generation of porous tubular type air distributor are evenly intensive inadequately, thereby cause whole fermentation unit ventilatory effect to be affected, exist fermentation abundant inadequately, have the lower problem of fermentation efficiency.
The utility model content
The utility model purpose: for the ventilatory effect that solves the air-distributor of fermentation unit in the prior art bad, and fermentation inadequately fully, problem that efficient is low excessively, a kind of liquid submerged fermentation pore type breather has been proposed.
Technical scheme: for reaching above-mentioned purpose, the utility model can be by the following technical solutions: a kind of liquid submerged fermentation pore type breather, comprise body, agitator, producer gas generator, also comprise the pore type ventilation device that is positioned at described agitator below, described pore type ventilation device comprises compressed air line and circular ring pipe, and described circular ring pipe is provided with the micropore air sparger that level is installed; Described compressed air line one end links to each other with producer gas generator, the other end links to each other with circular ring pipe.
More preferred, described body comprises cylindrical shell and reverse taper, and described reverse taper is welded in the bottom of described cylindrical shell.
For making whole fermentation unit discharge more convenient, described reverse taper bottom is provided with blow-off valve.
Further, described blow-off valve is located at the reverse taper cone tip part.
More preferred, described micropore air sparger is the porous ceramics rod.
In order to make the more intensive even of bubble generation, described micropore air sparger is 8, and is evenly distributed on the described circular ring pipe.
Beneficial effect: a kind of liquid submerged fermentation pore type breather that the utility model provides, by pore type air-distributor structure Design, and the application of porous ceramic film material, can make the bubble of effusion become small, intensive and even, it is slower than common air pocket that small bubbles rise to the speed of liquid level from the device bottom, thereby increased gas and liquid duration of contact; Meanwhile, the agitator that is installed in pore type air-distributor top makes liquid form turbulent flow, making small bubbles is not that straight line rises, but line rises in the shape of a spiral, small bubbles run duration and distance in liquid have been prolonged, thereby make the meltage of oxygen increase greatly, ventilatory effect is improved, thereby has improved fermentation efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, the utility model discloses a kind of liquid submerged fermentation pore type breather, comprise body, producer gas generator, pore type ventilation device and agitator 6, wherein upper part of body is that the bottom of cylindrical shell 1, body is reverse taper 2; Producer gas generator is an air compressor machine;
The pore type ventilation device is positioned at cylindrical shell 1 inside, and the pore type ventilation device comprises air compressor machine, compressed air line 3 and circular ring pipe 4, and circular ring pipe 4 is provided with the micropore air sparger 5 that stupalith that 8 levels install is made; Compressed air line 3 one ends link to each other with air compressor machine, the other end is stayed internal tank by gas valve and be connected with circular ring pipe 4, agitator 6 is positioned at the top of micropore air sparger 5, the top of agitator 6 is circumscribed with drive-motor after passing the top of cylindrical shell 1, cone tip part at reverse taper 2 is provided with discharge gate and blow-off valve 7, and the micropore air sparger is the porous ceramics rod.
In the present embodiment, when fermented liquid ferments in the body, can open air compressor machine,, import pressurized air in the body and carry out aeration by compressed air line 3, circular ring pipe 4 and micropore air sparger 5.Small bubbles good dispersity from the 5 intensive effusions of micropore air sparger, and it is slower than common air pocket that small bubbles rise to the speed of liquid level at the bottom of the jar, gas and liquid are increased duration of contact, and meanwhile, the agitator 6 that is installed in micropore air sparger 5 tops is opened, make liquid form turbulent flow, make bubble be not straight line rise but in the shape of a spiral line rise, prolonged bubble run duration and distance in liquid, increased the meltage of oxygen, promote the carrying out of aerobic fermentation, improved fermentation efficiency.
