Description

Technical Field

[0001] The utility model relates to the technical field of conveying and fermentation, in particular to a batch type dry fermentation acidification prevention device. Background Art

[0002] Fermentation generally refers to the process of using microorganisms to manufacture industrial raw materials or products. It is carried out by microorganisms (bacteria, yeast, etc.), organic matter (mainly carbohydrates), culture medium, etc. under certain conditions such as temperature and pH. Batch anaerobic dry fermentation has a high content of organic solids, which makes it difficult to ensure the homogeneity of the fermentation process and energy transfer is difficult, which can easily cause local acidification problems, and in severe cases, it can cause fermentation failure.

[0003] At present, the measures taken by anaerobic fermentation to prevent acidification or recover from acidification are: 1. Adding alkaline substances, such as chemical reagents, reflux spraying of biogas slurry, reflux of leachate, etc.; 2. The system can enhance resistance through gradual domestication; 3. Inoculation of high-quality composite bacterial agents; 4. Stirring system; 5. Increasing inoculation amount; 6. Adjusting the substrate C / N ratio to an appropriate range, such as combined fermentation.

[0004] However, all of the above methods have disadvantages. Adding chemical reagents will increase costs; spraying biogas slurry from above requires gradual penetration and a long recovery time, and during the penetration of biogas slurry, the number of microorganisms reaching the lower part is reduced due to the adsorption and interception of materials; domestication takes a long time and continuous operation is difficult for dry fermentation; it is difficult to cultivate highly active anaerobic microorganisms through conventional breeding or bioengineering methods, and progress is slow. Even if it is achieved, it is difficult to maintain the balance of the bacterial community when the strain or bacterial agent is put into the biogas fermentation process; dry fermentation has a high solid content, stirring operation is more difficult, and the mechanical agitator is highly abrasive and energy-consuming; increasing the inoculation amount will reduce equipment utilization.

[0005] Based on the above problems, in order to improve the stability of the anaerobic dry fermentation system, this scheme designed a targeted anaerobic dry fermentation device that can directly reach the "lesion". Utility Model Content
