Description

technical field

[0001] The invention belongs to the technical field of chemical production equipment, and relates to production equipment for lime, coking and calcium carbide products, in particular to a production device for calcium carbide co-production coking products. Background technique

[0002] Calcium carbide, commonly known as calcium carbide, reacts with water to form acetylene. Acetylene is an important chemical raw material, mainly used in the production of polyvinyl chloride-based, vinyl acetate-based and acrylic-based products. More than 70% of PVC products in my country are derived from acetylene produced by calcium carbide. The price increase of petroleum products has stimulated the development of calcium carbide industry.

[0003] In industry, the fixed bed-arc method is generally used in the production of calcium carbide. The high temperature generated by the arc is used to heat the lime and coke in the calcium carbide furnace to above 2000°C, and stay fo...
