Abstract
The utility model discloses an air inlet distributor of a fermentation tank, which comprises an annular pipeline, wherein the annular pipeline is provided with an air inlet end and an air outlet end; the end of giving vent to anger is seted up upper tube hole crowd and lower tube hole crowd above and below the ring channel for the symmetry, and upper tube hole crowd corresponds on with lower tube hole crowd and installs the nozzle, and the nozzle slope is arranged on the ring channel for nozzle blowout heliciform air current, the utility model discloses a set up the slope nozzle on the ring channel for slope nozzle blowout rotatory air current, thereby form the spiral air current in the fermentation cylinder, effectively increase the area of contact of gas and liquid, thereby improved dissolved oxygen efficiency.
Description
Technical Field
The utility model relates to a fermentation cylinder, in particular to fermentation cylinder air inlet distributor.
Background
The aerobic bacteria require oxygen for propagation, and sufficient oxygen distribution can promote the vigorous growth of the bacteria. The air distributor in the aerobic microorganism fermentation tank body is a device for introducing sterile air into the tank body, and the air distributor is arranged in the tank body, so that the rising speed of bubbles is reduced, and the stirring power can be reduced by about 10% on the premise of not changing the original stirring system. The structural form of the air distributor has a great influence on the dissolved oxygen rate. The prior art discloses a gas distributor for a fermentation tank, which is disclosed as CN209098670U and comprises an annular pipeline, wherein the annular pipeline is provided with a gas inlet end and a gas outlet end, and the defect that the fermentation tank has the problem of low dissolved oxygen efficiency due to the structure is overcome.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fermentation cylinder air inlet distributor improves fermentation cylinder dissolved oxygen efficiency.
The purpose of the utility model is realized like this: an air inlet distributor of a fermentation tank comprises an annular pipeline, wherein an air inlet end and an air outlet end are arranged on the annular pipeline; the end of giving vent to anger is seted up for the symmetry and is gone up tube hole crowd and lower tube hole crowd on the ring conduit upper and lower, go up the tube hole crowd and correspond on the tube hole crowd and install the nozzle, the nozzle slope is arranged on the ring conduit for nozzle blowout heliciform air current.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a set up the slope nozzle on the ring conduit for the rotatory air current of slope nozzle blowout, thereby form the helical airflow in the fermentation cylinder, effectively increase the area of contact of gas and liquid, thereby improved dissolved oxygen efficiency.
As a further limitation of the utility model, the upper pipe hole group and the lower pipe hole group include a plurality of pipe holes, and the pipe holes are evenly opened on the circular pipeline. So that the gas is sprayed more uniformly, and the gas is further contacted with the liquid more sufficiently.
As a further limitation of the present invention, each of the nozzles has a 30 ° horizontal plane included angle with its corresponding radius. The rotation of the gas during spraying is ensured, and the mutual influence of the gas flow is avoided.
As a further limitation of the present invention, each of said nozzles is at an angle of 7 ° to 15 ° to the horizontal.
As the utility model discloses a further inject, the nozzle is crisscross with the contained angle interval of horizontal plane and is set up, and the contained angle of two adjacent nozzles and horizontal plane is 7 and 15 respectively.
As the utility model discloses a further inject, the inlet end links to each other with outside air supply through the intake pipe.

Detailed Description
The fermentation tank air inlet distributor shown in fig. 1-2 comprises an annular pipeline, wherein an air inlet end and an air outlet end are arranged on the annular pipeline 1, and the air inlet end is connected with an external air source through an air inlet pipe; the end of giving vent to anger is seted up on the looped pipeline 1 for the symmetry, lower top tube hole crowd and lower tube hole crowd below, top tube hole crowd corresponds on with lower tube hole crowd and installs nozzle 2, 2 slopes of nozzle are arranged on looped pipeline 1, make 2 blowout heliciform air currents of nozzle, top tube hole crowd, lower tube hole crowd includes a plurality of tube hole 1a, and tube hole 1a evenly sets up on looped pipeline 1, each nozzle 2 corresponds the horizontal plane contained angle position 30 between the radius rather than tube hole 1a, nozzle 2 sets up with the contained angle interval of horizontal plane is crisscross, two adjacent nozzles 2 are 7 and 15 respectively with the contained angle of horizontal plane.
The utility model discloses the during operation will the utility model discloses arrange the bottom of fermentation cylinder in, let in gas through the intake pipe from the lateral part of ring channel, spout in the nozzle 2 that the slope set up gas to form the spiral air current, make its and liquid fully contact.
The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
