Thermoelectric waste gas recovery device

The utility model discloses a thermoelectric waste gas recovery device, relates to the field of thermoelectricity, and aims to treat waste gas exhausted by a natural gas generator set. The thermoelectric waste gas recovery device comprises a cooling tower, an absorption tower, a release tower, a condensation tower and a heat exchange device. The absorption liquid in the absorption tower captures and fixes the carbon dioxide in the waste gas, and is heated in the release tower to release the carbon dioxide; and the obtained carbon dioxide is input into a gas storage tank for storage after beingcooled, purified, compressed and the like. The thermoelectric waste gas recovery device can recover carbon dioxide contained in combustion waste gas of natural gas, remove harmful gas such as sulfurdioxide and carbon monoxide, reduce atmospheric pollution and restrain the greenhouse effect to a certain extent. According to the thermoelectric waste gas recovery device, waste heat of waste gas iseffectively used as a heat
