Description
Technical field
The utility model relates to the microbial fermentation field, particularly a kind of air-distributor and comprise its fermentor tank.
Background technology
Biotechnology is the industry of giving priority to of 21st century, and it is widely used among all conglomeraties such as medicine, food, light industry, agricultural chemicals and biochemical industry, and has realized microbiotic, amino acid, veterinary drug, agricultural chemicals and the biological production of taking care of.In biotechnology, the equipment of most critical is fermentor tank, and its volume of fermentor tank can reach 500-800m
3, the cubic capacity of the fermentor tank of a production plant generally surpasses upper ten thousand stere.
The function of fermentor tank is for microbial growth provides good condition, in order to satisfy microbial growth and breeding.In fermentor tank, these biological performance its catalysis and metabolic functions also produce the metabolite that the conventional chemical reaction is difficult to obtain.In microbial growth and metabolic process, the external world need to be to a large amount of oxygen of supply in fermentor tank.Pulverizing and the mixing effect of the agitator in tank by fermentation, these oxygen are dispersed into small bubbles by air pocket and are dissolved in fermented liquid so that for microorganism.
Because the even distribution of oxygen bubbles is directly determining fermentation level, therefore study and develop and aly can realize that oxygen bubbles evenly is mixed in the bottom, tank skin of fermentor tank and the air-distributor of tank central authorities is fermentation field research staff's pursuit always.In addition, because air-distributor is the equipment that energy consumption is higher, therefore air-distributor rational in infrastructure also has an important significance aspect energy-saving and emission-reduction.
As shown in Figure 1, existing fermentor tank comprises a tank body 1, a turning axle 2, a plurality of blade 3 and an air-distributor 4.As shown in Fig. 2-3, this air-distributor 4 comprises a bearing 20, an inlet pipe 41, a ring main 42 and a plurality of isocon 420.During use, as shown in Figure 1, pass into pressurized air by this inlet pipe 41, pressurized air will be full of this ring main 42 and be penetrated by those isocons 420, form string shape air pocket.Meanwhile, this turning axle 2 is subject to the motor drive on this tank body 1 top and drives those blades 3 rotations, in order to air pocket is broken into small bubbles and is dissolved in fermented liquid.
the airflow that penetrates through those isocons 420 is equally distributed in theory, but find in test experiments and actual use procedure near the air flow quantity at the mouth of pipe place of this inlet pipe 41 still greater than the mouth of pipe place air flow quantity away from this inlet pipe 41, namely a side tolerance is large and opposite side tolerance is less, thereby cause the very large radially impulse force that is subject to of this turning axle 2 and those blades 3, not only can cause larger shock to tank skin, also can make this turning axle 2 and those blade 3 off-axis to rotational vibration, therefore seriously affected this turning axle 2, the life-span of those blades 3 and this tank body 1.
Therefore, study and develop a kind of air-distributor that can alleviate radial impact power particularly necessary.

A kind of air-distributor, it comprises an inlet pipe, a ring main and a plurality of isocon, its characteristics are, this air-distributor also comprises fluid break-in parts, and it is that streamline and this radially are the fluid of an angle along the fluid break-in radially of this ring main that these fluid break-in parts are used for streamline.
Better, these fluid break-in parts be used for streamline along the fluid break-in radially of this ring main be streamline and this radially be an angle and be positioned at this ring main radially with the fluid on the axial determined plane of this ring main.
Better, these fluid break-in parts are a round platform, the angle of the bus of this round platform and the axis of this round platform is 1 ° to 30 °.
Better, these fluid break-in parts are a hollow round table, the angle of the bus of this hollow round table and the axis of this hollow round table is 1 ° to 30 °.
Better, these fluid break-in parts are the sleeve of a ring section, the axis of this sleeve and the dead in line of this ring main.
Better, between the mouth of pipe of the bore of each isocon and this isocon and this ring main apart from positive correlation.
Better, those isocons are distributed on the tube wall of this ring main.
Better, the ring surface of this ring main is annular.
A kind of fermentor tank, it comprises a tank body, a turning axle and a plurality of blade, and its characteristics are, and this fermentor tank also comprises air-distributor as above.
Positive progressive effect of the present utility model is:
The utility model provides a kind of air-distributor.By increasing this fluid break-in parts, this air-distributor has advantages of that radial impact power is little.

Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Fig. 4-5, the air-distributor 8 of the present embodiment comprises the sleeve 83 of an inlet pipe 81, a ring main 82, a plurality of isocon 820 and a ring section, the dead in line of the axis of this sleeve 83 and this ring main 82.The bore of those isocons 820 equates and is distributed on the tube wall of this ring main 82, and the ring surface of this ring main 82 is annular.The diameter of this sleeve 83 is less than the diameter of this ring main 82.
The ring surface of this ring main 82 also is not limited to annular, can also be polygon annular, and for example positive hexagon is annular or positive eight side ring shapes, as long as can change the flow direction of the fluid that is ejected by those isocons 820.
This sleeve 83 is used for radially the fluid break-in of streamline along this ring main 82, so as to make streamline after break-in and this radially be an angle and be positioned at this ring main 82 radially with the axial determined plane of this ring main 82, namely be transformed into axial motion by radial motion, as shown in streamline in Fig. 49, therefore alleviated the radial impact power to turning axle, blade and tank body.
When producing, these fluid break-in parts also are not limited to sleeve-shaped, some entity round platforms or hollow round table also can use, and also can realize stopping fluid and reach the function that changes flow direction, finally also can reach and alleviate fluid to the technique effect of the radial impact power of turning axle, blade and tank body.Manufacture middle discovery, the angle of the bus of this round platform and the axis of this round platform is that in the situation of 1 ° to 30 °, effect is better.In addition, find in the research and development experimentation under the positively related design conditions of distance between the mouth of pipe of the bore of each isocon and this isocon and this ring main, namely the bore of the isocon of close this ring main is less, and away from the larger situation of the bore of the isocon of this ring main, can also alleviate the radial impact power to this sleeve, and reach better result of use.
As shown in Figure 6, the present embodiment also provides a kind of fermentor tank, and it comprises a tank body 5, a turning axle 6, a plurality of blade 7, a bearing 60 and air-distributor as above 8.
During use, as shown in Fig. 4-6, pass into pressurized air by this inlet pipe 81, pressurized air will be full of this ring main 82 and be penetrated by those isocons 820, form string shape air pocket.Meanwhile, this turning axle 6 is subject to the motor drive on this tank body 5 tops and drives those blades 7 rotations, in order to air pocket is broken into small bubbles and is dissolved in fermented liquid.Because this sleeve 83 has fluid break-in function, will be originally axial motion along this ring main 82 along the fluid break-in radially of this ring main 82, so alleviated the radial impact power to turning axle, blade and tank body.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
