Calcium hydroxide production process and calcium hydroxide production line
The invention provides a calcium hydroxide production process, which comprises the steps of S1, crushing, S2, calcining, S3, digesting, S4, filtering, S5, dehydrating, S6, drying and S7, sorting, wherein a calcining furnace in the S2 adopts a gas calcining kiln, the S6 and the S7 are completed by adopting a drying device, the drying device comprises an outer cylinder and an inner cylinder, a rotating shaft for driving the inner cylinder to rotate is arranged in the inner cylinder, a plurality of middle cylinders are arranged between the outer cylinder and the inner cylinder, sieve pores are formed in the middle cylinders, and the outer cylinder and the inner cylinder are sequentially divided into a filter residue layer and a plurality of sorting layers from inside to outside; a cylinder bottom capable of being opened and closed is arranged at the bottom of the filter residue layer, a material collecting groove is formed in the bottom of the sorting layer, and the material collecting groove, the outer cylinder and the middle cylinders are arranged at intervals; and waste gas generated by the gas calcining kiln preheats crushed materials in the S and then is led to the inner cylinder.
本发明提供了氢氧化钙生产工艺，氢氧化钙生产工艺，包括以下步骤：S1破碎、S2煅烧、S3消化、S4过滤、S5脱水、S6干燥、S7分选；所述S2中的煅烧炉采用气烧窑，所述S6和S7采用干燥装置完成，所述干燥装置包括：外筒和内筒，内筒内部设置有带动内筒转动的转动轴，所述外筒和内筒之间设置有若干个中间筒，所述中间筒上设置有筛孔，将外筒与内筒由内而外依次分隔成一个滤渣层和若干个分选层；所述滤渣层底部设置有可启闭的筒底，所述分选层底部设置有集料槽，所述集料槽与外筒、中间筒间隙设置；所述气烧窑所产生的废气先对S中的破碎料进行预热，再通向内筒。
