Description

Carbon dioxide recovery system Technical Field The present invention relates to a carbon dioxide recovery system. Background In recent years, with the advancement of carbon neutralization, it is considered to separate and recover carbon dioxide contained in air from the air, and to use the recovered carbon dioxide in various fields. As a technique for separating and recovering carbon dioxide contained in air from air (DIRECT AIR Capture: direct air Capture), for example, a carbon dioxide recovery device of patent document 1 is known. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2023-45570 Disclosure of Invention Problems to be solved by the invention In the prior art described in patent document 1, a system in which a large-sized device dedicated to the separation and recovery of carbon dioxide from air is separately provided is adopted. Accordingly, it is desirable to efficiently recover carbon dioxide while suppressing the equipment cost as much as possible without providing a large-sized equipment dedicated only for the recovery of carbon dioxide. Means for solving the problems The carbon dioxide recovery system according to an embodiment of the present invention includes a supply line configured to supply air compressed by a compressor to a pneumatic device, and a carbon dioxide recovery device configured to separate and recover carbon dioxide from the air compressed by the compressor. The carbon dioxide recovery device is disposed between the compressor and the pneumatic device in the supply line. Drawings Fig. 1 is a circuit diagram for explaining a carbon dioxide recovery system in the embodiment. Detailed Description An embodiment of the carbon dioxide recovery system 10 is described below with reference to the drawings. The carbon dioxide recovery system 10 of the present embodiment is used in a factory. < Summary of carbon dioxide recovery System > As shown in fig. 1, the carbon dioxide recovery system 10 includes a supply line 11.
