Production line and production process for manufacturing low-cost high-purity calcium hydroxide powder
The invention belongs to the technical field of coatings, particularly relates to the field of production of calcium hydroxide, and particularly relates to a low-cost high-purity calcium hydroxide powder manufacturing production line and a production process. The low-cost high-purity calcium hydroxide powder manufacturing production line comprises a crushing device, a three-stage digestion device, a heat exchanger and a powder concentrator. Wherein the crushing device is configured to crush the lime raw material. The third-stage slaking device is in butt joint with the crushing device, and the third-stage slaking device is configured to receive lime raw materials discharged by the crushing device. A gas inlet pipe of the heat exchanger is communicated with a waste gas discharge pipe of the third-stage digestion device, a water inlet pipe of the heat exchanger is communicated with the water source, and a water outlet pipe of the heat exchanger is communicated with the third-stage digestion device. And the powder concentrator is connected with the three-stage digestion device and is configured to separate the produced calcium hydroxide powder according to the granularity.
