Abstract

The invention discloses a double-stage slaking device for calcium hydroxide production, and belongs to a production device for calcium hydroxide. The technical problems that existing process devices are complex, production cost is high, and efficiency is low are mainly solved. According to the technical scheme, the double-stage slaking device is characterized in that a raw material bin (1) is connected with a raw material receiving end (3) installed at the upper portion of a first-grade slaking tank (5) in a sealed mode through a raw material input channel (2), and a metering device is arranged on the raw material input channel (2); a discharging opening of the sealed first-grade slaking tank (5) is connected with a feeding opening of a second-grade slaking tank (7) in a sealing-fit mode, a dehumidification collecting device (16) is installed at the upper portion of the waistline of the second-grade slaking tank (7) in a matched mode, and a second-grade discharging connector (8) of the second-grade slaking tank (7) is connected with a discharging pipe (9) in a sealing-fit mode. The environmental pollution caused by accident leakage during production can be avoided, energy conservation and emission reduction are achieved, and the double-stage slaking device is mainly applied to the field of calcium hydroxide production.

Description

technical field [0001] The invention relates to a production equipment of calcium hydroxide, in particular to a process line capable of realizing continuous production of calcium hydroxide. Background technique [0002] Slaked lime can be widely used in water treatment, leather industry, papermaking, industrial boiler, desulfurization, deacidification, chemical building materials and other industries. Require. The production of calcium hydroxide has changed from the era of traditional original lime digestion process to the era of continuous production by production equipment, and has experienced multiple development cycles, which is caused by the change of lime deep processing process. At the earliest, the simple artificial digestion process was adopted, with low output and poor quality of finished products, which could only meet the needs of the low-end market. With the development of processing technology, lime mixing equipment appeared, which can mix lime with water for ...
