Abstract
The utility model belongs to the biotechnology field, which is applicable to a bioreactor. It provides a stirring device which can make gas and liquid be mixed for many times and form circular flow. The device consists of a compressed air pipe 1, a jet guiding pipe 2, an air suction pipe 3, a distributor 4 and a reaction tank 5. The device can mix gas and liquid for multiple times and form a circular flow, achieves good mass and heat transfer effects, has an energy-saving effect of about 40 percent, has a good dissolved oxygen effect, is simple in structure, is convenient to operate and clean, and can be suitable for the transformation of the traditional mechanical stirring tank.
Description
The utility model belongs to biological technical field, is applicable to bioreactor.
At present, countries in the world all are being devoted to develop the high-efficiency and energy-saving type bioreactor, emerge polytype interior circulation, outer circulation reactor, but all there are some weakness in these reactors, as gas distributor that various types is arranged in the jar and deflector etc., give operation, clean and bring many inconvenience.
The purpose of this utility model provides a kind of agitating device that makes gas-liquid repeatedly mix and form circulation.
The purpose of this utility model is achieved in that
As shown in Figure 1, the pipe 1 of compressed air side under the biological reactor enters, and enters by the shower nozzle ejection of managing 1 top and draws jet pipe 2 and mix with mash.Pure air above the mash and foam are mixed with mash equally by air intake duct 3 inlet tubes 2 that draw jet pipe 2 one sides; Upwards spray by pipe 2 through mixed gas-liquid mixture, rush at distributor 4, the kick plate 6 of distributor 4 blocks from drawing gas, the liquid mixture of jet pipe 2 ejections, and it is concentrated to current collector 7, rise from anemostat 8 shuntings then, drive mash and produce circulation up and down, thereby realize good repeatedly mixing and circulation, reach desirable mass-and heat-transfer effect.
Describe the utility model concrete structure in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model by biological reactor 5, distributor 4, air intake duct 3, draw jet pipe 2 and compressed air hose 1 is formed.It is characterized in that: the bottom of biological reactor 5 feeds compressed air hose 1, draws jet pipe 2 and is sleeved on outside the pipe 1, and a side of drawing jet pipe 2 is communicated with air intake duct 3, draw jet pipe 2 above distributor 4 is housed.Distributor 4 is by curved surface kick plate 6, and current collector 7 and anemostat 8 are formed, and it is characterized by: an end of curved surface kick plate 6 projection that makes progress forms current collector 7, and anemostat 8 is fixed on the below of kick plate 6.
The utility model has the advantages that:
1. removed the mechanical agitation system of traditional biological reactor, it is empty to take full advantage of compression The energy of gas. Through repetition test, on probation, the energy-saving effect of fermentation tank part can reach 40% left side Right.
2. reuse the pure air in the tank, improved the dissolved oxygen effect, strengthened stirring Ability, and automatic defoaming function is arranged.
8. simple in structure, there are not complicated gas distributed system and deflector in the tank body, be convenient to operation and cleaning.
4. this device can be used for the transformation of traditional mechanical agitator tank.
Claims (2)
1. gas circulation agitating device that is used for bioreactor, it by biological reactor 5, distributor 4, air intake duct 3, draw jet pipe 2, compressed air hose 1 is formed, drawing jet pipe 2 is sleeved on outside the compressed air hose 1, it is characterized in that: compressed air hose 1 is positioned at the bottom of biological reactor 5, one side of drawing jet pipe 2 is communicated with air intake duct 3, draw jet pipe 2 above distributor 4 is housed.
2. gas circulation agitating device according to claim 1 is characterized in that distributor 4 is made up of curved surface kick plate 6, current collector 7 and anemostat 8; One end of curved surface kick plate 6 projection that makes progress forms current collector 7, and anemostat 8 is fixed on the below of kick plate 6.
