Preparation process and preparation device of high-purity calcium hydroxide
The invention discloses a preparation process and a preparation device of high-purity calcium hydroxide. The process comprises the following steps: crushing blocky raw materials, digesting calcium oxide, carrying out water distribution reaction and winnowing a finished product. The device comprises a feeding unit, a crushing unit, a winnowing tower and a storage tower. A discharge pipe is arranged at the bottom of the storage tower; a grinding chamber is arranged above the winnowing tower, a winnowing chamber is arranged below the winnowing tower, a winnowing machine is arranged on one side in the winnowing chamber, and an air inlet with a dustproof unit is formed in the outer side of the winnowing chamber; and the crushing unit and the winnowing tower are respectively provided with a corresponding air inlet unit. According to the device, the crushing unit and the grinding chamber are additionally arranged, large-particle or caked calcium hydroxide is crushed and ground, it is ensured that the calcium hydroxide is fully ground into fine particles, the situation that the calcium hydroxide cannot be abandoned as impurities through winnowing is prevented, resource waste is reduced, and economic losses are reduced; the method has the advantages that large-particle or caked calcium hydroxide can be effectively treated, the calcium hydroxide is prevented from being abandoned as impurities, resource waste is reduced, and economic loss is reduced.
本发明公开了高纯度氢氧化钙制备工艺及制备装置,其工艺包括块状原料粉碎、氧化钙消化、配水反应和风选成品；其装置包括上料单元、破碎单元、风选塔和储存塔；储存塔底设出料管；风选塔上为研磨室，下为风选室，风选室内部一侧设风选机，风选室外侧设带防尘单元的进风口；破碎单元和风选塔均设有各自对应的进风单元。本发明装置通过加设破碎单元和研磨室，对大颗粒或结块的氢氧化钙进行破碎、研磨，确保充分磨碎成细小颗粒，防止其无法通过风选被作为杂质废弃，减少了资源的浪费，降低了经济损失；本发明具有能对大颗粒或结块的氢氧化钙进行有效处理，防止其被作为杂质废弃，减少资源浪费，降低经济损失的优点。
