Abstract

The invention discloses a calcium oxide production device and production method. According to the method, a calcining tower is used as a reaction device, industrial waste carbide slag is used as a rawmaterial, reasonable drying, preheating and calcining zone arrangement are carried out on equipment in the calcining tower, the material is subjected to preheating dehydration outside the tower and drying-presintering-calcining process treatment in the tower, a calcium oxide product with the purity of more than 85% is synthesized, and the product yield is more than 90%. High-temperature-resistantfluidized vibrating screens made of silicon carbide, ceramic and other materials are arranged in the calcining tower drying and pre-calcining treatment area so that the materials entering the calcining area can be in full contact with a heat source, and the ignition loss of the materials is increased; the device is simple in structure, small in occupied area and high in energy utilization efficiency, meanwhile, efficient cyclic utilization of the carbide slag is achieved, and industrial production is facilitated.

Description

technical field [0001] The invention relates to a calcium oxide production device and a production method, belonging to the technical field of calcium oxide production technology. Background technique [0002] Calcium carbide slag is a solid waste residue mainly composed of calcium hydroxide produced when calcium carbide is used to produce acetylene. It contains about 85-95% calcium hydroxide and 1-10% calcium carbonate. Carbide CaC 2 The process of wet production of acetylene with water as raw material is simple and mature, and it still accounts for a large proportion in my country at present. The specific chemical reactions involved are: [0003] [0004] According to the above reaction calculation, in the actual industrial production process, adding water to 1 ton of calcium carbide can generate more than 300 kg of acetylene gas, and at the same time produce about 20 tons of calcium carbide slurry with a solid content of 10-13%. Acetylene is the main raw material fo...
