Problems solved by technology

[0004] At present, most of the EO equipment produced by many domestic factories do not have a reliable exhaust gas treatment system, and a few designed waste gas harmless treatment systems are called water dissolution methods, which are actually a useless and extremely irresponsible discharge into space.

Abstract

The invention discloses a method and a device for processing ethylene oxide waste gas. The method comprises the following steps: step one, employing a vacuum pump to pump the sterilized ethylene oxide waste gas into a chemical combination apparatus for carrying out a chemical combination reaction with concentrated sulfuric acid to produce ethylene glycol, and regularly discharging ethylene glycol to be used as an industrial raw material; step two, allowing remaining ethylene oxide gas to go into a turbulent ball chemical combination tower under the action of a gas-liquid pump, and further carrying out hydration degradation with an aerated water flow of 85-95 DEG C in the turbulent ball chemical combination tower; and step three, allowing hot water discharged by the turbulent ball chemical combination tower to flow into an aeration tank to carry out aeration oxygenation and the like. The method and the device are suitable for harmless treatment of the ethylene oxide waste gas in a large-scale disinfection center, have good treatment effect, can realize zero emission, and have great significance for environmental restoration and natural friendship.

Description

technical field [0001] The invention belongs to the technical field of ethylene oxide sterilization waste gas treatment, and in particular relates to a treatment method and device for ethylene oxide waste gas. Background technique [0002] Ethylene oxide (EO), also known as ethylene oxide, is a colorless liquid at low temperature, with an aromatic ether smell, a boiling point of 10.8°C, and a density of 1.52; ethylene oxide is flammable and explosive, and its minimum burning concentration is 3%. . Ethylene oxide gas has strong bactericidal power and wide bactericidal spectrum, and can kill various microorganisms including bacterial spores. It is a bactericidal agent. [0003] Ethylene oxide does not damage sterilized items and has strong penetrating power, so most items that are not suitable for sterilization by general methods can be sterilized and sterilized with ethylene oxide. For example, electronic instruments, optical instruments, medical equipment, books, documents...
