Description

Technical Field

[0001] The utility model relates to the technical field of defoaming, in particular to a defoamer foam stirring device. Background Art

[0002] During the production process of fermentation food industries such as the brewing industry, a large amount of fermentation gas is generated. Among them, carbon dioxide gas, as a commonly used raw material in industrial production, has high application value. At the beginning, due to the low understanding of the utilization value of carbon dioxide and the lack of environmental protection, the fermentation gas was often directly discharged into the atmosphere, which not only caused serious environmental pollution and aggravated the greenhouse effect phenomenon, but also greatly wasted the utilization value of carbon dioxide and a large amount of energy.

[0003] Therefore, people began to consider recovering and purifying the carbon dioxide gas generated in the fermentation industry. At present, some CO2 defoaming and washing system equipment has emerged. However, in the current CO2 defoaming and washing system equipment, a large amount of foam is generated in the fermentation tank, and the foam contains the gas from the fermentation tank, which seriously affects the recovery efficiency. Usually, the method of spraying washing water is used to extinguish the foam, which will waste a large amount of water. Summary of the Utility Model
