[0002] With the acceleration of industrialization, large-scale CO2 emissions caused by fossil fuel combustion have become a global environmental problem. Traditional carbon capture and storage (CCS) technology mainly targets point source emissions (such as power plants, steel mills), but has limited effect on non-point source emissions that are scattered and difficult to manage. Therefore, DAC emerged as a new negative emission technology. Air carbon dioxide capture (DAC) equipment is a technical device specially designed to capture carbon dioxide directly from the atmosphere. This type of equipment separates low-concentration CO2 in the air through chemical or physical methods, and stores or converts it into other useful forms, such as synthetic fuels, building materials, etc.

[0003] However, the existing air carbon dioxide capture equipment is prone to have local dead angles when air is introduced, and the absorption liquid cannot contact carbon dioxide, resulting in uneven air intake, which leads to inaccurate capture effect when the alkaline absorption liquid such as potassium hydroxide solution chemically absorbs carbon dioxide. Therefore, there is an urgent need for an air carbon dioxide capture equipment to solve the above problems. UTILITY MODEL CONTENT

[0006] Further, the extended shaft is fixed in the rotating inner cylinder at the lower end.

[0007] Further, a plurality of honeycomb exhaust holes are arranged at the lower end of the annular side surface of the carbon dioxide capturing tank.

[0008] Further, an annular fixing rail is embedded in the inner side surface of the carbon dioxide capturing tank, and the hole-equipped support plate is slidably arranged in the inner side of the annular fixing rail.

[0009] Further, a detachable door is arranged at the left side of the front end of the carbon dioxide capturing tank by means of bolts.
