CARBON DIOXIDE REMOVAL DEVICE, CARBON DIOXIDE DESORPTION DETERMINATION METHOD, AND CARBON DIOXIDE SEPARATION METHOD

To provide a carbon dioxide removal device which can determine whether or not carbon dioxide is desorbed from an adsorbent, without using a carbon dioxide sensor.SOLUTION: A carbon dioxide removal device includes a carbon dioxide adsorption module, a first valve provided in a suction part of the carbon dioxide adsorption module, a second valve provided in an exhaust part of the carbon dioxide adsorption module, a third valve connected to the exhaust part, a vacuum pump connected to the carbon dioxide adsorption part through the third valve, and a control part. The carbon dioxide adsorption module includes a pressure measurement part and an adsorbent, and the control part performs at least one of determination of presence/absence of desorption of carbon dioxide from the adsorbent, and detection of abnormality, on the basis of the pressure measured by the pressure measurement part.SELECTED DRAWING: Figure 2 【課題】二酸化炭素センサーを用いることなく、吸着材から二酸化炭素が脱離したか否かを判定することが可能な二酸化炭素除去装置を提供すること。【解決手段】二酸化炭素除去装置は、二酸化炭素吸着モジュールと、二酸化炭素吸着モジュールの吸気部に設けられた第１のバルブと、二酸化炭素吸着モジュールの排気部に設けられた第２のバルブと、排気部に接続された第３のバルブと、第３のバルブを介して二酸化炭素吸着部に接続された真空ポンプと、制御部とを備え、二酸化炭素吸着モジュールは、圧力測定部及び吸着材を備え、制御部は、圧力測定部が測定した圧力に基づいて、吸着材からの二酸化炭素の脱離の有無の判定、及び、異常の検知のうちの少なくとも一方を行う。【選択図】図２
