Description

Technical Field

[0001] The utility model relates to the technical field of microorganisms, in particular to a device for treating tail gas of microbial fermentation. Background Technique

[0002] The device for treating tail gas of microbial fermentation is an environmental protection technology, mainly used to treat the tail gas generated in the industrial production process, especially those gases containing harmful substances such as volatile organic compounds (VOCs), sulfides, ammonia, etc. With the development of industrial production, the problem of tail gas emission is becoming increasingly serious, threatening the environment and human health. Traditional physical and chemical treatment methods have problems such as high cost, low efficiency, and secondary pollution. The microbial fermentation technology uses the biodegradation ability of specific microorganisms to convert harmful substances in the tail gas into harmless or low-toxic substances, such as carbon dioxide and water. This method has the advantages of high treatment efficiency, low cost, and no secondary pollution. The technology for treating tail gas of microbial fermentation has developed rapidly in the past few decades. Researchers have improved the stability and efficiency of the treatment device by screening and cultivating highly degradable microorganisms and optimizing the fermentation conditions.

[0003] During the actual use process, if the filter screen is designed complexly or the fixing method is not user-friendly, it may lead to a cumbersome replacement process, requiring professional tools or a long time, increasing the maintenance difficulty and cost. If the filter screen cannot be replaced according to the specific composition or concentration of the tail gas, it may not be able to effectively meet the tail gas treatment requirements under different working conditions, restricting the adaptability and flexibility of the equipment. The difficult-to-replace filter screen may lead to an extended maintenance cycle, increasing the downtime and maintenance cost of the equipment. If the filter screen cannot be replaced in time, its filtration efficiency may decrease with the increase of use time, affecting the purification effect of the entire tail gas treatment device. If the filter screen is damaged or blocked and not discovered and replaced in time, it may affect the normal operation of the tail gas treatment device and even cause safety accidents.
