Coal ash carbon sequestration device and use method thereof

The invention relates to the field of coal ash carbon sequestration, in particular to a coal ash carbon sequestration device and a using method thereof. The invention provides a coal ash carbon sequestration device which is convenient for carbon dioxide to permeate into coal ash slurry, improves the utilization rate of the coal ash slurry and fully reacts the coal ash slurry with the carbon dioxide and a use method thereof. The coal ash carbon sequestration device comprises a box body, a box door plate, fixing bolts and the like, the box door plate is rotatably mounted on the box body through a hinge, the two fixing bolts are rotatably arranged on the box body and the box door plate through threads, and coal ash slurry flows in a shallow and thin state, so that carbon dioxide can conveniently enter the coal ash slurry; substances such as calcium oxide and magnesium oxide in the coal ash slurry can fully react with the carbon dioxide, so that the utilization rate of the coal ash slurry is increased, and the ai
