Abstract

The invention discloses a calcium hydroxide continuation production process and a dedicated production line, the calcium hydroxide continuation production process belongs to a calcium hydroxide production process, and mainly aims to solve complex process equipment, high production costs, low efficiency and other technical issues in the prior art. The technical program elements are that: the dedicated production line includes a material distribution device, digestion tanks and a sorting machine, the material distribution device is connected via a transfer mechanism with an inlet of a digestion device, the digestion device is at least provided with two digestion tanks which are connected in turn, an outlet and an inlet of adjacent digestion tanks are connected in turn, a sorting machine feed inlet and the digestion tank outlet are communicated via a transfer mechanism, sorting machine outlets comprise a powder outlet and a slag outlet, a powder separator wind outlet is connected with a material storage tank, and is communicated with a finished product output mechanism, and a closed loop is formed by mutual seal connection. The dedicated production line can prevents the environmental pollution caused by accidental leaks during production, is energy-saving and emission-reducing, and is mainly used in the field of production of calcium hydroxide.

Description

technical field [0001] The invention relates to a production process of calcium hydroxide, in particular to a process method capable of realizing continuous production of calcium hydroxide and a process line for 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, ...
