The invention provides a carbon capture
system for
flue gas total heat
recovery, which is characterized in that an absorber is respectively connected with a condenser, an
evaporative cooler and a solution
heat exchanger through pipelines, the solution
heat exchanger is connected with a generator through a pipeline, the first condenser is connected with a water tank, and the
evaporative cooler is connected with an absorption
tower; the lean and rich liquid
heat exchanger is respectively connected with the
desorption tower, the
evaporative cooler, the absorber and the first condenser; the upper end of the
desorption tower is connected with the second condenser, the lower end of the
desorption tower is connected with the
reboiler, one end of the MEA rich liquid pump is connected with the absorption tower, the other end of the MEA rich liquid pump is divided into two sub-paths which are respectively connected with the absorber and the first condenser, one end of the MEA barren liquid pump is connected with the
reboiler, and the other end of the MEA barren liquid pump is connected with the barren and rich liquid heat exchanger. The invention further provides a carbon capture method for
flue gas total heat
recovery. According to the invention, the consumption of steam is reduced, the temperature of the absorption tower can be reduced, the combination of
carbon dioxide in the absorption tower is promoted, and the
trapping efficiency is improved.
