Description
Technical field
Micropore bubbling fermentation reaction tank relates to the fermentation reactor technical field.
Background technology
In fermentation reaction, the liquid phase fermentation reaction is that fermented bacterium is thrown in retort, under suitable condition, makes growth breeding, fermentation generate the purpose product.The oxygen-supplying amount that how effectively to improve fermented liquid is related to fermentation production rate, and the contact surface area that increases liquid phase and oxygen can improve productive rate, shortens fermentation time.Prior art is that the bubble that in the fermentation reaction tank, in the mechanical stirring mode, will be filled with retort blends into tiny bubble, increase the solution-air contact surface with this, but the mechanical stirring device energy consumption is high, the mechanical stirring device complex structure, and facility investment is large.
Common bubbling whipping appts is that bubbling pipe is arranged on the retort bottom, bubbling micropore opening up.Chinese patent CN201887067U discloses bubbling stirring-type liquid-replenishing device with texturing tank, but its complex structure, adopt the bubbling form of the production well on square tube, air-flow is realized the stirring to material in retort with the production well of horizontal direction vertically upward by square tube, this kind of whipping appts, the deficiency existed, first production well vertically upward, the initial velocity direction is vertically upward, the ascent rate of bubble is also vertically upward, after the bubble disengagement production well, with two speed, synthetic upward velocity direction hightails liquid phase fermentation interface, solution-air is short duration of contact, the liquid phase material of retort bottom is difficult to contact with bubble, form solution-air contact dead angle, place, the discontiguous dead angle of gas-liquid can cause the miscellaneous bacteria breeding of anaerobism mushroom, and quality product is descended, and the bubbling pipe complex structure of this device, sterilizing and washing difficulty when replacing product or fermentor tank have miscellaneous bacteria.Chinese patent CN112078778A is simple in structure, and clean and maintenance is convenient, but exists equally the retort bottom to be prone to the problem at solution-air contact dead angle.
Summary of the invention
The defect existed in order to overcome above-mentioned prior art, the application's purpose is to provide a kind of fermentation materials of each point in the fermentation reaction tank that can make all can fully contact with oxygen, without solution-air contact dead angle, simple in structure, be convenient to change and the cleaning reaction tank, be easy to install, micropore bubbling fermentation reaction tank with low cost.
Micropore bubbling fermentation reaction tank, comprise at the bottom of discharge port 1, bubbling micropore 2, bubbler 3, heat tracing layer 4, fermentation reaction tank 5, opening for feed 6, butterfly valve 7, DO controller 8, ventilating pit 9, end socket 10, inlet pipe 11, tank 12, it is characterized in that: fermentation reaction tank 5 lower central are equipped with bubbler 3, and bubbler 3 connects inlet pipe 11; Fermentation reaction tank 5 bottom side connect inlet pipe 11, and end socket 10 is positioned at fermentation reaction tank 5 tops, and opening for feed 6 is housed on end socket 10, and butterfly valve 7 is housed on opening for feed 6; Ventilating pit 9 is housed on end socket; Described bubbler 3 is mouse cage shape, and its top is cylindrical, and bottom is the inverted triangle cone-shaped, and the outside surface of bubbler 3 mouse-cage bodies has bubbling micropore 2.
Described micropore bubbling fermentation reaction tank is characterized in that: at the bottom of tank, 12 for elliptical arc surface, and discharge port 1 is positioned at the bottom of tank 12 central authorities.

Described micropore bubbling fermentation reaction tank is characterized in that: described opening for feed 6 is 200-300mm for diameter, and described butterfly valve 7 diameters are 200-300mm.
Beneficial effect
Micropore bubbling fermentation reaction tank, because bubbler 3 is mouse cage shape, its top is cylindrical, bottom is the inverted triangle cone-shaped, bubble enters the fermentation reaction system, part transverse movement, the bubble that the micropore on the inverted triangle cone surface of mouse-cage body bloats moves towards oblique below, through fermentation reaction tank 5 bottoms, because being subject to the buoyancy of reaction system liquid phase material and the effect of material resistance, then risen gradually by fermentation reaction tank 5 bottoms, do not stay solution-air contact dead angle, can effectively prevent the growth and breeding of anaerobism miscellaneous bacteria, guarantee the stable of quality product;
Under the application's fermentor tank, bubble enters fermentation reaction tank movement locus and extends, and mean residence time extends thereupon, is beneficial to the biological fermentation reaction; The solution-air contact more fully can reduce the power consumption of bubbling;
Substitute the ring flange opening for feed of the usual application of prior art with butterfly valve 7, open butterfly valve 7 during charging, close butterfly valve 7 during reaction, charging is opened and is reacted time sealing simple to operateization of switch opening for feed while making charging and reaction, and it is that 200-300mm guarantees the unobstructed of charging that opening for feed 6 and butterfly valve are selected diameter;
On described fermentation reaction tank 5 top end sockets 10, DO controller 8 is housed and is convenient to the monitoring to the fermentation reaction temperature;
The outside surface of bubbler 3 mouse-cage bodies has the opening direction of bubbling micropore 2 bubbling micropores 2 towards oblique below, and bubbler 3 is by towards oblique below to towards the fermentation reaction tank diameter to excessively, make bubble at the fermentation reaction tank diameter being uniformly distributed to direction;
The application's micropore bubbling fermentation reaction jar structure is simple, with low cost.
