Abstract
The present disclosure provides a sterilization exhaust gas treatment system, which may include a gas liquefaction recovery system, a pressure swing adsorption recovery system, a reaction system, a temperature swing adsorption recovery system, a hydration system, a recovery and storage system, and a wastewater treatment system. The gas liquefaction recovery system, the pressure swing adsorption recovery system, the reaction system, the temperature swing adsorption recovery system, and the hydration system may be fluidly connected in sequence through first connecting pipes. The gas liquefaction recovery system, the pressure swing adsorption recovery system, and the temperature swing adsorption recovery system may each be fluidly connected to the recovery and storage system through second connecting pipes. The hydration system may be fluidly connected to the wastewater treatment system through wastewater pipes. The present disclosure also provides a method for treating ethylene oxide-containing sterilization exhaust gas using the sterilization exhaust gas treatment system.
