According to embodiment, a carbon dioxide capturing system cools a regenerator discharge gas discharged from a regenerator 5 containing carbon dioxide by a cooling unit 8, and then sends the gas to a cleaner 9. The cleaner 9 receives condensed water generated from the regenerator discharge gas cooled by the cooler 9, and a gaseous cooled regenerator discharge gas, and cleans the cooled regenerator discharge gas by a cleaning liquid. The cleaner 9 has a first liquid reservoir 9b configured to store the condensed water, and a second liquid reservoir 9c configured to store the cleaning liquid having cleaned the cooled regenerator discharge gas.

A device and method for atomizing and degassing is provided. The device includes a first condenser, a second condenser, a packed tower and a fan. The first condenser is provided with a first feed inlet, a first discharge outlet, a first water inlet and a first water outlet. The packed tower is provided with a feed inlet, an air outlet and a liquid outlet. The first discharge outlet of the first condenser is connected with the feed inlet of the packed tower, a second feed inlet of the second condenser is connected with the air outlet of the packed tower, and a gas outlet of the second condenser is connected with the fan. Packing is arranged in the packed tower, and the packing is located between the feed inlet and the air outlet, and the feed inlet is located between the air outlet and the liquid outlet.
