Description
Technical field
The utility model relates to stirred fermentor field, is specifically related to the transformation of air lift type stirred fermentor tuyere structure.
Background technology
Airlift fermentor is most widely used biologic reaction equipment.This kind of reactor have structure simply, high, the low power consumption and other advantages of not easily microbiological contamination, dissolved oxygen efficiency.Airlift fermentor has broad variety, common are airlift loop, bubbling style, blast injection etc., the airlift fermentor that biological industry has been widely applied has the two tower aerial fermentation tank spraying air-lift loop fermentor tank, be provided with Multi-layers distributing plate of circulation fermentation pot in gas lift, gas-liquid.Bubbling tank is then the most original air blow tank, does not arrange guide shell in certain bubbling style reactor, therefore does not control the main body directed flow of liquid.
Airlift fermentor utilizes air nozzle to spray air at a high speed, air is scattered in liquid with bubble type, in the side of ventilation, liquid mean density declines, in airproof side, fluid density is comparatively large, thus produces and produces density difference with the liquid of ventilation side, thus form the circulation of fermentation pot liquid.Airlift fermentor has various ways, comparatively common are internal recycle tubular type, outer circulation tubular type, pulling force cartridge type and vertical partition plate formula.The circulation tube design of outer circulation type is outside at tank body, and inner circulating tube is two, and design and installation is in tank interior.The advantage of airlift fermentor is that energy consumption is low, and the effect of cutting of decocting in liquid is little, and structure is simple.Under same energy consumption, its oxygen transmission capacity is more much higher than mechanical agitation type air blow tank.
Airlift fermentor can be widely used in the aerobic fermenting processs such as microbiotic, amino acid, zymin, VITAMIN, organic acid.Solution-air, gas-liquid-solid reaction process is can be used in chemical industry.Sewage disposal is can be used in environmental protection.This equipment is at home for L-glutamic acid, microbiotic, xanthan gum, saccharifying enzyme, citric acid production at present, achieves the economic benefit of highly significant after coming into operation.Ferment necessary air inside and outside static mixing element on current downflow, drive fermentation liquid circulation, promote solution-air fully mix.
Airlift fermentor of the prior art also exists gas and mixes with fermented liquid uneven, cause reflecting slowly, and the shortcomings such as blocking easily occurs tuyere.
Utility model content
The utility model provides air lift type stirred fermentor, solves airlift fermentor gas of the prior art and mixes with fermented liquid uneven, cause reflecting slow problem; Easily there is the problem blocked in the tuyere also solving fermentor tank.
For solving the problem, the utility model adopts following technical scheme: air lift type stirred fermentor, comprises tank body 1, and tank body 1 bottom is provided with air and imports adapter 2, and tank body 1 top is provided with air vout 3; Pulling force cylinder 4 is vertically provided with in tank body 1; Tank body 1 is outside equipped with some chucks 5; Air imports adapter 2 one end in tank body 1 and connects air nozzle 6; The shape of air nozzle 6 is spherical; The spherical upper semisection of air nozzle 6 is evenly distributed with some tuyeres 7; Upper part of air nozzle 6 is deep into the lower end of pulling force cylinder 4; Air nozzle 6 and air are imported between adapter 2 and are connected by screw thread.
Advantage of the present utility model: air jet of the present utility model is provided with some tuyeres, can be sprayed onto all directions by air time jet, gas is fully mixed with fermented liq, accelerates fermenting speed, makes reaction more abundant; Meanwhile, multiple tuyere can prevent the generation of tuyere latch up phenomenon effectively.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is air nozzle schematic diagram of the present utility model.
Nomenclature in figure: tank body 1, air imports adapter 2, air vout 3, pulling force cylinder 4, chuck 5, air nozzle 6, tuyere 7.
Embodiment
by best embodiment, the utility model is described in detail below
.
As shown in Figure 1, air lift type stirred fermentor, comprises tank body 1, and tank body is identical with the structure of existing airlift fermentation tank body, is made up of stainless steel.Tank body 1 bottom is provided with air and imports adapter 2, and tank body 1 top is provided with air vout 3; Pulling force cylinder 4 is vertically provided with in tank body 1; Tank body 1 is outside equipped with some chucks 5; Air imports adapter 2 one end in tank body 1 and connects air nozzle 6; Fermentor tank structure of the present utility model adopts existing pulling force cartridge type airlift fermentor.This fermentor tank relies on gas to produce directed circulation, but not impeller pump class mechanical means, therefore liquid form is determined, liquid circulation is strong, and inner movement-less part, has less shear-stress, the advantages such as waste of energy is even.
As shown in Figure 2, the shape of air nozzle 6 is spherical; The spherical upper semisection of air nozzle 6 is evenly distributed with some tuyeres 7; Upper part of air nozzle 6 is deep into the lower end of pulling force cylinder 4; Many tuyeres of the present utility model arrange the contact area that effectively can increase air and fermented liquid, increase reaction efficiency, and many tuyeres can effectively reduce the generation of tuyere latch up phenomenon simultaneously.Air nozzle 6 and air are imported between adapter 2 and are connected by screw thread, adopt and are threaded and can conveniently change tuyere, can be disassembled dredge when tuyere blocks, and have saved the cost that equipment runs.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
Claims (2)
1. air lift type stirred fermentor, comprises tank body, and tank body bottom is provided with air and imports adapter, and tank body top is provided with air vout; Pulling force cylinder is vertically provided with in tank body; Tank body is outside equipped with some chucks; It is characterized in that, air imports adapter one end in tank body and connects air nozzle; The shape of air nozzle is spherical; The spherical upper semisection of air nozzle is evenly distributed with some tuyeres; Upper part of air nozzle is deep into the lower end of pulling force cylinder.
