Technical Field
[0001] The utility model belongs to the technical field of tail gas treatment, in particular to a fermentation toxic tail gas treatment device. Background Art
[0002] Bio-fermentation is a process that uses microorganisms or cells to convert organic matter into the desired product. It is widely used in food, feed, medicine, chemical and other industries. During the bio-fermentation process, a large amount of tail gas will be generated, which may contain harmful substances such as bacteria, toxins, dust, impurities, etc. If it is directly discharged without treatment, it will cause serious harm to the environment and human body. Therefore, effective treatment of fermentation tail gas is an important link to ensure the safety and environmental protection of bio-fermentation process.
[0003] At present, there are mainly the following methods for treating fermentation tail gas:
[0004] Physical method: Use cooling, condensation, filtration and other physical means to separate the moisture, dust and impurities in the exhaust gas, reduce the temperature and concentration of the exhaust gas, and reduce the pollution level of the exhaust gas. The advantages of this method are simple operation and low cost, but the disadvantage is that it cannot effectively remove bacteria and toxins in the exhaust gas, and there are still certain risks.
[0005] Chemical method: using chemical reactions such as oxidation, reduction, neutralization, and adsorption to convert harmful substances in tail gas into harmless or low-harm substances, or adsorb them on solid carriers, so as to achieve the purpose of purifying tail gas. The advantage of this method is that it has good treatment effect and can effectively remove bacteria and toxins in tail gas, but the disadvantage is that the operation is complicated, the cost is high, and secondary pollution may occur.
[0006] Biological method: using microorganisms or plants to degrade or absorb organic matter in tail gas, thereby reducing the pollutants in tail gas. The advantages of this method are environmental protection and no secondary pollution, but the disadvantages are slow processing speed, low efficiency, and great influence of environmental conditions.

Therefore, there is an urgent need for a new type of fermentation tail gas treatment device that can perform multiple treatments on the fermentation tail gas to ensure the safe discharge of the tail gas and avoid harm to the environment and human body.
