Energy-saving and emission-reducing calcium oxide production method
The invention discloses an energy-saving and emission-reducing calcium oxide production method, and relates to the technical field of chemical production. The method comprises the following steps: S1, calcining limestone; s2, collecting the calcined product into a storage box according to a block shape; in the calcination process of the step S1, waste gas generated by calcination is drained and introduced into a storage box, and after the waste gas generated by calcination enters the storage box from the top of the storage box, the waste gas is discharged from the bottom side of the storage box and is discharged into the atmosphere through a waste gas tower; after calcination in the step S1 is completed, the effective calcium content of calcium oxide entering the storage box is larger than 90%, and the effective calcium content of calcium oxide in contact with waste gas in the storage box is larger than 85% and smaller than 90%; on the premise of ensuring the quality of calcium oxide, even if the yield is increased, the emission of waste gas can be reduced, and the purposes of increasing the yield and reducing emission are achieved.
本发明公开了一种节能减排氧化钙生产方法，涉及化工生产技术领域。本发明包括以下步骤：S1：煅烧石灰石；S2：将煅烧完成后的产物按照块状收入储存箱中；在进行步骤S1的煅烧过程中，将煅烧产生的废气进行引流，引入至储存箱中，让煅烧产生的废气从储存箱的顶部进入后，再从储存箱的底侧排出通过废气塔排至大气中；步骤S1中煅烧完成后，进入储存箱中的氧化钙的有效钙含量大于90%，在储存箱中与废气接触后的氧化钙的有效钙含量大于85%小于90%；以实现在保证氧化钙质量的前提下，即便是增产，也能够减少废气的排放，实现增产减排的目的。
