Description
Technical field
The utility model relates to a kind of fermentation equipment, particularly a kind of fermentor tank.
Background technology
In the concrete activity in production of biological pesticide technology manufacturing enterprise, often use fermentor tank.Existing fermentor tank air inlet is the single tube bottom inflow, stirs and adopts three roads, six straight leaf turbine oars, and air is smashed bubble by paddle after the pot bottom that ferments enters, and is dissolved in the feed liquid.The ratio that this kind mode sterile air is dissolved in the feed liquid is little, and utilization ratio is low, and required power of agitator is big, thereby has caused the waste of the energy; In addition, the cooling tube that existing fermentor tank adopted has dual mode, and a kind of is shell and tube, organize more tubulation in jar along tank body circumferential direction uniform distribution, every group of tubulation is all by outside water-in and the water outlet pass-out tank body; Another kind is the deep bid tubular type, and a coil pipe is from up to down along the inner tank wall setting, also by outside a water-in and the water outlet pass-out tank body.Ponding is difficult for emptying in the shell and tube cooling tube, when feeding steam, " water attack " phenomenon takes place easily, makes body produce leak or slit easily; Deep bid tubular type cooling tube needs the people to enter in the tank body and keeps in repair as breaking down, and is very inconvenient.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides a kind of fermentor tank, this fermentor tank has solved fermentor tank of the prior art to the sterile air dissolving defective that ratio is little, utilization ratio is low, required power of agitator is big, and it can emptying cooling ponding, keeps in repair also very convenient.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of fermentor tank, comprise tank body and stir shaft, tank body is provided with manhole, inlet pipe and tapping hole, vertically be provided with the array cooling tube in the tank body, and along tank body inner periphery direction uniform distribution, outside the water-in at cooling tube two ends and the water outlet pass-out tank body, described stir shaft is by the axis hole and the axle sleeve and the stent support that are located at tank interior at tank body top, the turbine slurry is installed on the stir shaft, be provided with the annular jet sparger in the described tank body and be fixed on tank base by bracing frame, the annular jet sparger comprises ring-type tracheae base and several jet nozzles, the jet nozzle is provided with air inlet port, tuyere and feed liquid inlet, the jet nozzle becomes 30-60 degree angle with the plane at ring-type tracheae base place, and ring-type tracheae base intracavity is connected with inlet pipe; Described cooling tube is a coil pipe, and the size of this coil pipe is less than the diameter of manhole.
As preferably, described annular jet sparger is two groups, and the jet nozzle becomes miter angle with the plane at ring-type tracheae base place, and every group of annular jet sparger is provided with 20-30 jet nozzle, and fermentor tank is provided with guide shell.
As preferably, described turbine oar is oblique leaf turbine oar and para-curve turbine oar.
As preferably, every group in described coil pipe vertically segmentation distributes, and the two ends of every section coil pipe all are interlinked to the outside by water-in and water outlet and tank body.
Compared with prior art, advantage of the present utility model is: after adopting said structure, when air-flow outwards sprays at a high speed in tuyere, feed liquid is sucked from the feed liquid inlet around the jet nozzle by air-flow, mixing the back with gas in the jet nozzle sprays with gas, form fine and closely woven bubble, strengthened the dissolved oxygen effect; Because the jet nozzle is that horizontal plane becomes miter angle with plane, ring-type tracheae base place, drive the feed liquid rotation during gas-liquid ejection, sense of rotation is consistent with mixing direction, thereby significantly reduced the resistance that stirs, spray obliquely owing to tuyere simultaneously, drive feed liquid and upwards stir from guide shell inside, rotary wind type turbine oar drives feed liquid and flows downward, and has further increased the dissolution time of air in feed liquid.The utility model can be saved sterile air 20%, and power of agitator can reduce 40%-50%.In addition, because cooling tube adopts small coils, effectively ponding is cooled off in emptying on the one hand, on the other hand because coil size less than people's bore dia, can be taken out coil pipe convenient for maintaining from manhole.Every group in coil pipe vertically segmentation distributes, and has realized the segmentation cooling on the one hand, and on the other hand as break down, the one section dish that only needs to break down takes out and keeps in repair, and does not need whole group coil pipe is pulled down.
