Abstract

The embodiment of the present invention provides a lime preparation device and a lime preparation method, including a heating device, a belt calciner and a cooling fan; The paving machine, and the screening and collecting mechanism arranged under the discharge end of the trolley; the trolley is divided into a preheating section, a calcination section and a cooling section in turn; the preheating section, the calcination section, and the cooling section There are gas hoods on the top and bellows on the bottom; pipe connections are provided on the top of each gas hood and the bottom of the bellows; the hot air outlet of the heating device is connected with the gas hood of the calcination section by pipelines; the cooling fan and the cooling The bellows are connected by pipes. The raw materials on the belt calciner are heated by the hot air with stable temperature and pressure supplied by the heating device, which shortens the lime calcination time, and because the belt calciner has a large amount of material, the production efficiency of the lime preparation process is greatly improved, which can be Significantly increase the stand-alone production capacity of lime preparation.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a lime preparation device and a lime preparation method. Background technique [0002] Lime is calcium oxide (CaO), which is widely used in iron and steel industry, calcium carbide industry, alumina industry, refractory materials and other industries. It is also one of the necessary production raw materials in these large-scale industrial fields. of steel requires about 70 kg of lime. The main raw material for making lime is limestone, and the main component of limestone is calcium carbonate (CaCO 3 ), the basic principle of burning lime is to use high temperature to decompose calcium carbonate in limestone into calcium oxide and carbon dioxide. The basic reaction formula for the decomposition of calcium carbonate in limestone into calcium oxide and carbon dioxide is CaCO 3 →CaO+CO2↑-1777.4kJ / kgCaCO3. Under the heating condition of the lime kiln, in order to make ...
