Abstract
The utility model relates to a bioengineering field, the three-phase of mainly being applicable to bioreactor's gas, liquid and solid mixes. It provides a gas mixer which can simplify the structure of the reactor and reduce the energy consumption. It is characterized by that it is formed from compressed air pipe, air suction pipe, liquid suction pipe, gas distributor and throat pipe, and the top ends of all three pipes are equipped with spray heads. The novel oxygen-transferring device has the advantages and the characteristics of simple structure, small height-diameter ratio of the reactor, high oxygen transfer rate, good stirring effect, capability of automatically defoaming, convenience in installation, easiness in cleaning, remarkable energy-saving effect and the like, and generally can save energy by about 1/3-1/2. Therefore, the method has high economic value.
Description
The utility model relates to bioengineering field, is applicable to that mainly the gas, liquid, solid three-phase of bioreactor (fermentation tank) mixes.
The prior biological reactor is mostly used mechanical agitation, and the gas, liquid, solid three-phase in the zymotic fluid is mixed.This reactor, because of the employing mechanical agitation, complex structure, energy consumption is bigger.
The purpose of this utility model provides and a kind ofly can make vitals---the air and liquid mixer that bioreactor construction is simple, energy consumption reduces.
The purpose of this utility model is achieved in that
As shown in Figure 1, compressed air is entered by pipe 1, penetrates at a high speed by its end sprayer, entrainments the gas in the pipe 2, simultaneously the gas on the reactor liquid level is sucked.At this moment, from managing gas flow that 2 spouts penetrate air demand greater than pipe 1.This strand gas enters pipe 3 throats, and entrainments mash, from managing 3 ejections, rushes at reactor bottom then, mixes with mash.Because the buoyancy of gas will promote mash and move upward, form mash and circulate up and down.Dispersed preferably for bubble is had, be provided with gas distributor 4 in the blender bottom, make fining air bubbles, the contact-making surface of increase and mash, thus improve the dissolved oxygen effect.
Below, concrete structure of the present utility model is described in conjunction with the accompanying drawings.As shown in Figure 1, the utility model is by compressed air hose 1, air intake duct 2, and pipette 3, gas distributor 4 and trunnion 5 are formed.It is characterized in that: hit exactly be compressed air hose 1, air intake duct 2 be sleeved on the pipe 1 outside, the pipe 3 be sleeved on the pipe 2 outside.Gas distributor 4 is sleeved on pipe 3 belows.All there is shower nozzle pipe 1, pipe 2, pipe 3 lower ends.
The utlity model has following advantages:
1. owing to saved the mechanical agitation system, and enter gas flow in the mash again greater than the air demand of air compressor machine, therefore, energy-saving effect is remarkable. And tank body is more big, and is energy-conservation more remarkable, generally can reach about 1/3～1/2;
2. enter the 2-3 that gas flow in the mash is generally the air compressor machine air demand and doubly (require design according to zymotechnique), dissolved oxygen speed improves more than 2 times than mechanical agitation;
3. manage 2 in the air-breathing while, the foam on mash top can be sucked simultaneously, therefore have automatic defoaming function;
4. the ratio of height to diameter of reactor is little, and is suitable with mechanical agitator tank, is convenient to install, clean.
Claims (2)
1, a kind of bioreactor air and liquid mixer, it is characterized in that: it is made up of compressed air hose 1, air intake duct 2, pipette 3, gas distributor 4 and trunnion 5, positive center is a compressed air hose 1, and air intake duct 2 is sleeved on outside the compressed air hose 1, and pipette 3 is sleeved on outside the air intake duct 2; Gas distributor 4 is sleeved on pipe 3 belows; Pipe 2 and manage between the 3 top shower nozzles and to be trunnion 5.
2, air and liquid mixer according to claim 1 is characterized in that: shower nozzle all is equipped with in the lower end of compressed air hose 1, air intake duct 2 and pipette 3.
