Description
Technical field
The utility model relates to microorganism aerobic liquid state fermentation apparatus field, is specifically related to a kind of Horizontal liquid fermentation tank defoaming device.
Background technology
Usual aerobic bacteria fermentor tank is all vertical, and there are stirring system, cooling heat radiation system and ventilation bar device of air etc. in inside.Constantly expand along with fermentation-scale is produced greatly in industry, separate unit fermentor tank diameter, to be highly also multiplied.Fermentor tank diameter increases to present 4m ~ 10m from past 2m ~ 4m; Height increases to present 10m ~ 20m from past 5m ~ 10m.Because square being directly proportional of power of agitator and stirrer diameter, venting pressure are directly proportional to height of liquid layer in fermentor tank, therefore fermenter volume expand after power of agitator rises at double, venting pressure rises rapidly, finally cause energy consumption significantly to increase.
And in aerobic microbiological liquid state fermentation process ever-present bubble-related issues, foam be actually aerosol form colloid system, its disperse phase is air and metabolism gas, and external phase is fermented liquid, is separated from each other is not connected between foam across one deck liquid film.According to foam Producing reason, we sum up the rule of foam change: from the viewpoint of aeration-agitation, air flow is larger, and stir Shaoxing opera strong, then the foam produced is more; From the character of fermented liquid, in substratum, protein content is more, the viscosity of fermented liquid, and concentration is larger, then the froth stability generated is higher.From the viewpoint of thalline: during thalline vigorous growth, the foam produced is many, when fermented liquid Middle nutrition matrix is consumed in a large number by thalline, density loss, then the stability of bubble also weakens, after fermentation the phase, with the self-dissolving of thalline, make protein concn in fermented liquid increase again, then the whipability of fermented liquid strengthens again.Therefore, in fermentation period, the generation of each stage foam is the result of many factors comprehensive action, and each period changes greatly, and should make a concrete analysis of.For solving bubble-related issues in itaconic acid fermentation process, current most enterprise all adopts the mode adding defoamer to carry out froth breaking, but due to the rise of defoamer price, and the negative impact to feed liquid, therefore mechanical defoaming is more and more taken seriously.
Current mechanical defoaming is divided into froth breaking or the outer froth breaking of tank in tank.In tank, froth breaking installs rake froth breaking slurry exactly on stir shaft, and it rotates with stir shaft, utilizes row's rake teeth to be smashed by foam shear, although this mode is simple, defoaming effect is limited, very little for stream-like foaming.The outer froth breaking of tank guides to outside tank by foam, the booster action that depending nozzle produces or centrifugal force froth breaking, and the outer froth breaking of tank mainly contains orbiting vane, centrifugal force type etc.This froth breaking mode needs the size carrying out design motivation according to the water content of foam and viscosity.Based on above-mentioned present situation, can show no matter current mechanical defoaming is froth breaking or the outer equal existing defects of froth breaking self of tank in tank, especially when foam generates in a large number, promptly can not eliminate foam in time as defoamer.
