The second valve 21 on the corresponding gas transmission branch 2 and the first valve 11 on the main gas transmission line 1 are opened according to the gas transmission branch 2 where the unit tank 4 to be filled is located. Multiple unit tanks 4 are filled simultaneously through a single gas transmission branch 2. When it is necessary to change the gas transmission branch 2 to fill different unit tanks 4, the opening and closing states of the second valve 21 on the corresponding gas transmission branch 2 can be switched. The operation is convenient and reliable.

[0038] The carbon dioxide storage tank system for carbon capture according to the present disclosure can simultaneously fill the collected carbon dioxide gas into multiple unit tanks 4. After the unit tanks 4 are filled, they can be directly stored or transported, which greatly improves the filling and transfer efficiency of carbon dioxide gas.

[0039] Optionally, the storage tank system comprises a controller and an alarm, the controller is electrically connected with the first valve 11, the first flow meter, the first pressure gauge, the second valve 21, the second flow meter, the second pressure gauge, the third valve 31, the third flow meter and the third pressure gauge respectively, the controller is used for controlling the opening and closing of the first valve 11, the second valve 21 and the third valve 31, and the controller is used for collecting the flow measurement data of the first flow meter, the second flow meter and the third flow meter, when the deviation between the sum of the flow statistics of the plurality of third flow meters and the flow statistics of the first flow meter is greater than a set value or when the deviation between the sum of the flow statistics of the plurality of second flow meters and the flow statistics of the first flow meter is greater than a set value, the controller controls the alarm to send an alarm signal to review the connection sealing state of the plurality of unit tanks 4, thereby ensuring the reliability of the carbon dioxide gas filling.
