有している。(Prior art) As shown in Figure 2, a carbon dioxide removal device equipped with reactors 1 and 2 is operated by sequentially circulating one of the reactors 1 and 2 so that when one is in the absorption process, the other is in the regeneration process. Ta. With this method, immediately after the carbon dioxide absorbent is regenerated, the steam remaining inside the reactor, the carbon dioxide absorbent, and the amount of heat held by the reactor are transported by the treatment air and transported into the closed space at the start of the absorption process. The heat was either radiated to the outside of the system as waste heat through a cooler, or was released outside the system as waste heat through a cooler. For this reason, it has a drawback in that it does not make efficient use of thermal energy.

In the carbon dioxide removal method, the purified air outlet valve of one reactor and the treated air inlet valve of the other reactor are connected by a bypass pipe via a bypass valve, and the reactor immediately after regeneration is connected to the treated air inlet valve of the other reactor. The reactor was connected to the reactor through a bypass pipe line, so that the residual heat in the reactor immediately after regeneration was flowed to the regenerator immediately before regeneration for preheating.
