Description
technical field [0001] The invention relates to ethylene oxide gas treatment, in particular to an ethylene oxide residual gas treatment device and a treatment method thereof. Background technique [0002] Ethylene oxide (EO) gas is widely used in the sterilization and disinfection process of products due to its strong bactericidal power and wide bactericidal spectrum. Ethylene oxide is flammable, explosive, and toxic to the human body. And the residual ethylene oxide gas in the disinfection process should be treated, and it should not be discharged beyond the standard to prevent air pollution. At present, the domestic methods for dealing with ethylene oxide residual gas are generally water-soluble method and high-temperature catalytic combustion method. The water-soluble method is to use A large amount of ethylene oxide waste gas is directly passed into tap water, but this method has the following disadvantages: (1) Since the dissolution of EO requires a certain amount of ti...
