High-quality calcium oxide grading suspension calcination production line and suspension calcination process thereof
The invention belongs to the technical field of lime production, and particularly relates to a high-quality calcium oxide grading suspension calcination production line and a suspension calcination process thereof. A lime stone storage device is included. According to the high-quality calcium oxide grading suspension calcination production line and the suspension calcination process thereof, the purpose of improving the effective calcium content of a product is achieved, and the problems that an existing high-quality calcium oxide grading suspension calcination production line and a suspension calcination process thereof adopt a primary decomposition furnace, in the reaction process, calcium carbonate is decomposed to generate calcium oxide and carbon dioxide, if only primary decomposition is carried out, the concentration of carbon dioxide can be rapidly increased due to too large decomposition amount in unit time, and too high concentration can result in blockage of calcium carbonate decomposition, so that undecomposed calcium carbonate is mixed in finished product calcium oxide, the content of effective calcium is insufficient, and the actual effective calcium content can only reach 85% or slightly higher are solved, the effective calcium content of the product is improved, and the production quality is optimized.
本发明属于石灰生产技术领域，尤其为高品质氧化钙分级悬浮煅烧生产线及其悬浮煅烧工艺，包括石灰石储存装置。该高品质氧化钙分级悬浮煅烧生产线及其悬浮煅烧工艺，达到了提高产品有效钙含量的目的，解决了现有的高品质氧化钙分级悬浮煅烧生产线及其悬浮煅烧工艺原有技术为一级分解炉，由于反应过程中碳酸钙分解生成氧化钙与二氧化碳，仅进行一级分解的话，二氧化碳浓度会因为单位时间内分解量太大而快速上升，浓度过高则导致碳酸钙分解受阻，导致成品的氧化钙中混有未分解的碳酸钙，导致有效钙含量不足，实际有效钙含量只能达到百分之八十五或稍高的问题，提高了产品的有效钙含量，优化了生产质量。
