Abstract
A kind of airlift double-circulation fermenting tank device, including fermentor, the impeller of tank inner circulating tube and upper part, tank outer circulating tube and circulating pump and filtrated air pipe etc..During fermenting progress, the fermentation liquid of tank internal upper part squeezes into fermentor from fermenter base via tank outer circulating tube under the action of tank outer circulation pumps, and it is directly entered in tank inner circulating tube, filtrated air is squeezed into tank inner circulating tube from the bottom of fermentor together with fermentation liquid simultaneously, make to generate pressure difference inside and outside tank inner circulating tube using the power that filtrated air and fermentation liquid rise, so that the aperture that the liquid in fermentor passes through outside tank inner circulating tube on pipe enters in circulation pipe, and pass through from impeller upwards together with the fermentation liquid in pipe, to which impeller rotates, play the role of stirring and defoaming.Fermentation liquid outside tank with the circulation twice in tank so that material mixes sufficiently, improve utilization efficiency, stirring and the defoaming effect of impeller save the energy.
Description
Technical field
The utility model belongs to Zymolysis Equipment technical field, in particular to improves airlift fermentor gas-liquid mixed efficiency
Novel gas-lifting type fermentor device.
Background technique
So far, airlift fermentor is mainly used for the field of the aerobic fermentations such as antibiotic, amino acid.It is industrial used
Gas-lifting type circulation fermentation tank mainly fermentation liquid is injected into fermentor together with air by nozzle using circulating pump.
The material mixing efficiency of such airlift fermentor is not high, and needs the stirring of additional consumption energy progress fermentation liquid.
Summary of the invention
The purpose of this utility model is that solve original airlift fermentor radial circulation inefficient, gas-liquid mixed efficiency compared with
The problem of difference provides a kind of novel airlift double-circulation fermenting device.The utility model is in original airlift fermentation tank base
On realize fermentation liquid double circulation approach in tank, improve gas-liquid mixed efficiency and fermentation liquid Radial Flow efficiency.In tank
The top of inner circulating tube has installed impeller additional, can generate vortex under the effect of the high-speed gas-liquid mixture in tank inner circulating tube, make
The mash obtained in fermentor mixes well.
Novel gas-lifting type Two-way Cycle fermentor device provided by the utility model, the device include fermentor, in fermentor
Portion is provided with tank inner circulating tube (2), is equipped with tank outer circulating tube (3) outside fermentor, the upper end of tank outer circulating tube and fermentor
Top connection, the lower end of tank outer circulating tube is connected to the bottom of fermentor, the bottom of tank inner circulating tube respectively with fermentor outer bottom
The lower end connection of the filtrated air pipe and tank outer circulating tube in portion, the top of tank inner circulating tube is equipped with impeller (1).The tank outer circulation
Pipe is equipped with a circulating pump.The bottom periphery of tank inner circulating tube is equipped with one group of circulation aperture.
Ferment carry out during, the fermentation liquid of tank internal upper part under the action of tank outer circulation pumps via tank outer circulating tube from
Fermenter base squeezes into fermentor, to realize one cycle, improves thing liquid mixing efficiency.
Filtrated air is directly entered tank inner circulating tube from tank bottom, improves gas-liquid mixed efficiency, improves dissolved oxygen.
Make to generate pressure difference inside and outside tank inner circulating tube using the power that filtrated air and fermentation liquid rise simultaneously, so that fermentation
The circulation aperture that liquid in tank passes through pipe upper bottom portion outside tank inner circulating tube enters in tank inner circulating tube, and with the fermentation in pipe
The drain tank inner circulating tube from impeller upwards to form second of circulation in tank enables material to fill again to liquid together
Divide and mix, improves material mixing efficiency.
Filtrated air passes through at impeller together with fermentation liquid upwards in tank inner circulating tube, so that impeller rotates,
Play the role of stirring and defoaming, the energy needed for saving mechanical stirring.
The advantages of the utility model and good effect:
The utility model mainly improves original airlift fermentor, during fermenting progress, in tank
The fermentation liquid on top squeezes into fermentor from fermenter base via tank outer circulating tube under the action of tank outer circulation pumps, and directly
Into in tank inner circulating tube, while filtrated air is also squeezed into tank inner circulating tube from the bottom of fermentor together with fermentation liquid, benefit
Make to generate pressure difference inside and outside tank inner circulating tube with the power that filtrated air and fermentation liquid rise, so that the liquid in fermentor is from tank
The aperture passed through on pipe outside inner circulating tube enters in circulation pipe, and passes through from impeller upwards together with the fermentation liquid in pipe, from
And impeller rotates, and plays the role of stirring and defoaming.Fermentation liquid is outside tank with the circulation twice in tank so that material mixes
Sufficiently, utilization efficiency is improved, stirring and the defoaming effect of impeller save the energy.
Detailed description of the invention
Fig. 1 is airlift double-circulation fermenting tank apparatus structure schematic diagram.
Fig. 2 is impeller schematic diagram.
In figure, 1 impeller, 2 tank inner circulating tubes, 3 tank outer circulating tubes, 4 filtrated air pipes, 5 sampling pipes, 6 feed supplement holes, 7 pressures
Power table, 8 gas vents, 9 visors.
Specific embodiment
Embodiment 1:
As shown in Figure 1, 2, a kind of novel gas-lifting type Two-way Cycle fermentor device provided by the utility model, including fermentation
Tank, fermentor are internally provided with tank inner circulating tube (2), are equipped with tank outer circulating tube (3) outside fermentor, the upper end of tank outer circulating tube
It is connected to the top of fermentor, the lower end of tank outer circulating tube is connected to the bottom of fermentor, is set simultaneously on the tank outer circulating tube
There is a circulating pump.The bottom of the tank inner circulating tube lower end with the filtrated air pipe of fermentor outer bottom and tank outer circulating tube respectively
The top of connection, tank inner circulating tube is equipped with impeller (1).The novel gas-lifting type fermentor device, during fermenting progress,
The fermentation liquid of tank internal upper part squeezes into fermentor from fermenter base via tank outer circulating tube under the action of tank outer circulation pumps, and
It is directly entered in tank inner circulating tube, while filtrated air also squeezes into tank inner circulating tube from the bottom of fermentor together with fermentation liquid
In, make to generate pressure difference inside and outside tank inner circulating tube using the power that filtrated air and fermentation liquid rise, so that the liquid in fermentor
The aperture that body passes through outside tank inner circulating tube on pipe enters in circulation pipe, and passes through from impeller upwards together with the fermentation liquid in pipe
It crosses, so that impeller rotates, plays the role of stirring and defoaming.Fermentation liquid is outside tank with the circulation twice in tank so that material
Mixing sufficiently, improves utilization efficiency, and stirring and the defoaming effect of impeller save the energy.
