Description

technical field [0001] The invention relates to the technical field of lime production, in particular to a device and a process for producing highly active lime. Background technique [0002] The microcosmic characteristics of active lime are loose structure, abundant voids, and uniform and reasonable pore size distribution. In the production process, lime is divided into three types according to the calcining degree of lime, light burning, medium burning and over burning. The activity of light burning is the best, followed by medium burning, and the activity of over burning is the worst. Light-burned activated lime has high porosity, large specific surface area, fine grain, low bulk density and residual CO 2 Low content and other characteristics, the basic requirements should at least meet: porosity: >50%, specific surface area: 1.5-2.0㎡ / kg, crystal grain: 0.1-3μm, bulk density: 1.5-1.7g / cm 2 , Activity: > 300ml. [0003] With the deepening development of our count...
