Description

Ethylene glycol exhaust treatment device Technical Field The utility model relates to the technical field of waste gas treatment devices, in particular to an ethylene glycol waste gas treatment device. Background Ethylene glycol, also called glycol, is the simplest aliphatic diol, has the chemical property of alcohols, is colorless transparent viscous liquid, is a raw material for producing polyester resin, alkyd resin and polyester fiber, and is also used as an automobile antifreeze and an aircraft engine refrigerant. Ethylene glycol is miscible with water in any proportion over a temperature range of-30 ℃ to 150 ℃. In the chemical industry such as polymerization production, especially in the polyester production process, the polymerization equipment needs to discharge ethylene glycol waste gas periodically or aperiodically. In the prior art, glycol waste gas is generally treated by an active carbon adsorption method, a waste gas incineration method and a condensation method in the treatment process, the active carbon adsorption method needs to be frequently replaced for treating saturated active carbon, the waste gas incineration method can release carbon dioxide and aggravate greenhouse effect, and the condensation method needs to consume electric energy to convert gaseous glycol waste gas into liquid to be collected, so that energy consumption is caused. Therefore, a new solution is needed to solve at least one of the above technical problems. Disclosure of Invention In view of the above-mentioned shortcomings, the present utility model aims to provide a glycol waste gas treatment device, which can save energy, reduce pollution and has good waste gas treatment effect.
