| Zusammenfassung: | The invention provides a carbon dioxide capture rich liquid flash evaporation regeneration waste heat recovery system, which belongs to the technical field of carbon dioxide capture. The carbon dioxide capture rich liquid flash evaporation regeneration waste heat recovery system comprises an absorption tower, a regeneration tower, a lean and rich liquid heat exchanger and a flash evaporation tank, wherein the absorption tower and the regeneration tower are communicated through the lean and rich liquid heat exchanger, and the tower top of the regeneration tower is provided with a first cooling heat exchanger; and the flash evaporation tank is communicated between the lean and rich liquid heat exchanger and the first cooling heat exchanger. According to the carbon dioxide capture rich liquid flash evaporation regeneration waste heat recovery system, heat of lean liquid returned from the regeneration tower and heat of regeneration gas at the top of the regeneration tower are recovered in sequence through the low |
