Problems solved by technology

[0004] Due to the flammability, explosion and carcinogenicity of ethylene oxide, the control of ethylene oxide gas sterilization is still relatively difficult, especially the harmless treatment of ethylene oxide sterilization waste gas
The current widespread phenomenon is that after the ethylene oxide sterilizer is used, it directly discharges toxic and highly carcinogenic waste gas and waste liquid into the environment, causing a large amount of environmental pollution.

Abstract

The invention discloses a device and a method for treating sterilized ethylene oxide waste gas. The device comprises a gas pump, a chemical combination device (101), a gas-liquid pump (102), a turbulent ball tower (103) and a diffuser (4). The gas pump conveys ethylene oxide waste gas to the chemical combination device, and the ethylene oxide waste gas is chemically combined in the chemical combination device; ethylene oxide waste gas and a sulfonation reaction agent have a sulfonation reaction in the chemical combination device, and ethylene oxide is oxidized into carbon dioxide and ethylene glycol; the generated carbon dioxide and residual ethylene oxide waste gas are exhausted into the turbulent ball tower; and the residual ethylene oxide waste gas is output into the turbulent ball tower through the gas-liquid pump and is fully mixed and dissolved with hot water pumped into the turbulent ball tower by the gas-liquid pump.

Description

technical field [0001] The invention belongs to the technical field of ethylene oxide sterilization, and relates to an ethylene oxide sterilization waste gas treatment device and a treatment method. Background technique [0002] Ethylene oxide, 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, fur, cotton, chem...
