Abstract
The utility model discloses an air distribution device, which comprises a columnar air chamber. A nozzle spraying air to the periphery of a fermentation tank is disposed on a lateral wall approaching the bottom of the air chamber, and the nozzle is connected with a Venturi pipe. A nozzle end and a Venturi pipe end are both horn-shaped at a connection position of the Venturi pipe and the nozzle, and a horn-shaped opening of the Venturi pipe end is connected to a horn-shaped bottom of the nozzle end. The air distribution device is applied to fermentation process to increase fermentation quality, and saves cost.
Description
Technical field
The utility model relates to a kind of air distribution device, relates in particular to a kind of air distribution device of giving the bottom ventilation of fermentor tank.
Background technology
Generally adopt air directly to feed the bottom of fermentor tank in last century, along with improving constantly of understanding, begin to adopt the annular tube type air-distributor, leave many apertures on the endless tube, for keeping being evenly distributed of air, the area sum in general hole is 0.8 of an endless tube sectional area, most of company adopts the downward injection of air to loosen, injection direction is a jar end direction, part company adopts the air spray regime that makes progress, injection direction is lower floor's paddle direction, so that air ejection is after stirring arm is smashed, in a word, this time in stage is being studied always and how to make the bubble that sprays in the air-distributor littler, even have the people to bring into use the micro-pore aeration dish to test, but fermentation appearance is always undesirable.
The utility model content
At the problems referred to above, the technical problem that the utility model need solve provides a kind of fermented quality carefully, saves the air distribution device of cost.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of air distribution device, comprise the cylindrical air chamber, and be provided with jet nozzle around fermentor tank at sidewall near the wind box bottom, described nozzle connects Venturi tube.
Further: in above-mentioned air distribution device, in the junction of Venturi tube and nozzle, nozzle end and Venturi pipe end all are horn-like, and the hydraucone of Venturi pipe end connects at the bottom of the loudspeaker of nozzle end.Described nozzle can be a plurality of, but the nozzle total sectional area is less than 80% of wind box cross-sectional area.It also is provided with supports and the fixing support of Venturi tube, support is provided with the nut of regulating Venturi tube and wind box distance, Venturi tube can move to wind box, also can be to moving away from the wind box direction, and purpose is to regulate vacuum size in the Venturi tube.
Compared with prior art, in above-mentioned air distribution device, comprise the cylindrical air chamber, be provided with jet nozzle around fermentor tank at the sidewall near the wind box bottom, described nozzle connects Venturi tube.Whole air-distributor places the fermentor tank inner bottom part, be immersed in the fermented liquid, high pressure draft enters wind box by pipeline, inject Venturi tube at a high speed through nozzle, produce negative pressure, the liquid in the fermentor tank is involved in Venturi tube from the junction by negative pressure at nozzle and Venturi tube junction, acutely mix with high velocity air and reach the emulsive effect, thereby increased the contact area of gas and fermented liquid, slowed down the time that gas is overflowed in liquid, improved the dissolved oxygen in the fermented liquid.Abundant and gas blended fermented liquid flows out through the Venturi tube outlet, returns in the fermentor tank.Adopt this air distribution device, can make the gas-liquid mixed time shorten half, dissolved oxygen coefficient improves 30～50%, aspect energy-conservation, the experience proof is arranged under the prerequisite that does not change original stirring system, can fall the air consumption more than 30～40%.
Description of drawings
Fig. 1 is the sectional view of air distribution device of the present utility model;
Wherein, 1 wind box, 2 nozzles, 3 Venturi tubes, 4 junctions, 5 supports, 6 nuts, the outlet of 7 Venturi tubes.
Specific embodiments
Specify the utility model with reference to accompanying drawing 1.
With reference to Fig. 1: a kind of air distribution device, comprise cylindrical air chamber 1, be provided with jet nozzle 2 around fermentor tank at sidewall near wind box 1 bottom, described nozzle 2 connects Venturi tubes 3.In the junction 4 of Venturi tube 3 with nozzle 2, nozzle end and Venturi pipe end all are horn-like, and the hydraucone of Venturi pipe end connects at the bottom of the loudspeaker of nozzle end.Described nozzle total sectional area is less than 80% of wind box cross-sectional area.It also is provided with supports and the fixing support 5 of Venturi tube 3, support is provided with the nut 6 of regulating Venturi tube 3 and wind box 1 distance, Venturi tube 3 can move to wind box 1, also can be to moving away from wind box 1 direction, and purpose is to regulate vacuum size in the Venturi tube 3.Whole air-distributor places the fermentor tank inner bottom part, be immersed in the fermented liquid, high pressure draft enters wind box by pipeline, inject Venturi tube 3 at a high speed through nozzle 2, produce negative pressure, the liquid in the fermentor tank 4 is involved in Venturi tube 3 from the junction by negative pressure in nozzle 2 and Venturi tube 3 junctions 4, acutely mix with high velocity air and reach the emulsive effect, thereby increased the contact area of gas and fermented liquid, slowed down the time that gas is overflowed in liquid, improved the dissolved oxygen in the fermented liquid.Fermented quality is improved, save cost.
The above is a preferred embodiment of the present utility model, is not breaking away under the utility model design situation, carries out any conspicuous distortion and replacement, all belongs to the utility model protection domain.
