Abstract

The invention relates to an ethylene oxide exhaust gas processor. A pre-mixing chamber, a pre-heating chamber, a firebox, an adsorption chamber, a gas-distributing regulator and a cooling chamber which are mutually communicated are sequentially arranged upwards from an inlet of ethylene oxide exhaust gas. The gas-distributing regulator is communicated with the cooling chamber and is also communicated with a circulation fan. A jet circulation air intake and a vacuumizing port are arranged on the pre-mixing chamber. Heating pipes are arranged in the firebox and are interlaced orderly into layers, and the firebox is communicated with the adsorption chamber. A plurality of adsorbing layers are arranged in the internal part of the adsorption chamber, and a porous clapboard is respectively arranged between two layers, and the upper part of the adsorption is communicated with the gas-distributing regulator which can regulate the flow of high temperature purifying gas and circulation hot gas. The invention not only can lead the sterilized ethylene oxide gas to be thoroughly decomposed into carbon dioxide and water and lead the concentration of disposed and purified ethylene oxide nearly to be 0ppm which is further less than 1ppm regulated by the international standard, but also can lead the hot air to be recycled so as to conserve energy. The operation of the invention is convenient, and can be carried out together with sterilizing so as to avoid the secondary pollution.

Description

technical field [0001] The invention relates to a waste gas processor, in particular to an ethylene oxide waste gas processor. Background technique [0002] Ethylene oxide is referred to as EO, and its molecular formula is C 2 h 4 O, is a poisonous, flammable, and explosive substance with strong permeability and extensive sterilization properties, and has a wide range of applications. In the late 1980s, many developed countries widely used EO sterilization in chemical, medical, food, archaeological and other fields, such as unearthed cultural relics, contact lenses, human mucous membranes, blood contact appliances and chemical industries. It is most suitable to use EO for sterilization. However, if EO gas is inhaled into the lungs, dizziness, nausea, and dyspnea will occur, and excessive inhalation will cause death. There are such warnings in the process of using EO disinfection: cause cancer and cardiopulmonary failure and destroy reproductive function. Therefore, it is...
