Description

A kind of quick increasing drop oxygen device without stirring

Technical field

The utility model belongs to microbial fermentation equipment technical field, increases drop oxygen device more particularly to one kind.

Background technology

Need to determine to take aerobic fermentation or anaerobic fermentation according to demand during traditional microbial fermentation, in aerobic hair Often need to provide enough oxygen concentrations during ferment to ensure that fermentation is thorough, and need reduction oxygen dense in anaerobic fermentation process Spend to ensure that anaerobic bacteria preferably breeds, so as to obtain target product.By taking anaerobe fermentation as an example, it usually needs by zymotic fluid Oxygen concentration drop to it is very low be just easy to preferably fermentation, obtain higher product, conventional deoxygenation is all to enter line replacement with inert gas, Industrial acceptable inert gas is nitrogen, and because nitrogen and atmospheric density approach, and water oxygen concentration is affected by temperature, water Middle temperature more high oxygen concentration is lower, can cause microorganism dead when temperature exceedes microorganism tolerable temperature, and in water at normal temperature Oxygen concentration has a strong impact on anaerobic fermentation in 6-8ppm or so.In anaerobic fermentation process, problems be present, 1. are passed through nitrogen Pressure and flow and isolation efficiency between relation be difficult control；2. because the solution in fermentation tank contains dissolubility oxygen, normal Common nitrogen charging mode is difficult displacement dissolved oxygen under temperature, and efficiency is low；3. traditional nitrogen charging mode is because completely cutting off with replacement result not It is good, often there is the phenomenon that a large amount of losses of nitrogen waste；4. traditional nitrogen charging rushes oxygen mode and needs to be stirred continuously to obtain Effect preferably is filled with, but takes such a mode to waste time and energy.

The content of the invention

For above-mentioned the shortcomings of the prior art, the utility model, which provides one kind and can controlled, to be filled with pressure and stream Relation between the nitrogen or oxygen of amount and isolation efficiency, and during anaerobic fermentation, nitrogen displacement effect is good, efficiency high without stirring Quick increasing drop oxygen device.

Technical solution adopted in the utility model is：A kind of quick increasing drop oxygen device without stirring, including two pipes Road component, each pipeline assembly include magnetic valve, pipeline, universal adjusting device and bubble generator；It is described two Pipeline is arranged in fermentation tank, and each lower end of duct is connected by universal adjusting device with the bubble generator, often Individual pipeline upper end is mounted on the magnetic valve.

The beneficial effects of the utility model are：

1. nitrogen of the present utility model is discharged from the stud filter with hole, in discharge process, nitrogen is in titanium Rod filter surfaces form a large amount of bubbles, and a large amount of nitrogen bubbles finally drain residual oxygen in fermentation tank due to buoyancy emersion liquid level Gas, nitrogen blanket is formed, play isolation oxygen effect, the effect of nitrogen displacement oxygen is good and efficiency high.

2. the angle between bubble generator and pipeline is adjusted by universal adjusting device, can be in 90 degree to 180 degree angle, Line replacement can be entered to the oxygen of different azimuth.

3. the magnetic valve on two pipelines can be intermittently or serially open as needed and can maintain certain nitrogen or oxygen stream Amount, coordinated by the angle adjustment of bubble generator and pipeline, two magnetic valve alternation switches, the liquid in fermentation tank can flow Dynamic, mixing evenly, saves agitating device.

It 4. making two pipeline upper-lower positions adjustable by rotating two fall ways, can be freely lifted, two bubbles occur Device is dipped in the diverse location of fermentation pot liquid, is easy to the displacement of nitrogen or is filled with oxygen.

5. source of the gas selection can select nitrogen or oxygen according to purpose and demand, so as to reach the effect of deoxygenation or oxygenation.
