[0002] During the amino acid production process, a large amount of volatile raw materials will escape during the acylation, acidification, and centrifugal separation processes. The fermentation process of the amino acid strain will also produce fermentation waste gas with a foul odor. These substances are basically accompanied by a pungent odor, and when emitted into the air, a strong stench will be generated, which not only pollutes the atmospheric environment, but also poses a health hazard to workshop workers and surrounding residents. Therefore, the amino acid waste gas must be purified before it can be discharged in compliance with emission standards. Since the waste gas contains moisture, fixed particulate matter and gas, the existing waste gas treatment unit can usually only treat one phase.
