Description

technical field [0001] The invention belongs to the technical field of production of chemical basic raw materials, relates to calcium carbide production equipment, and in particular to a device for producing calcium carbide by utilizing solar energy. 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] The traditional calcium carbide production adopts the fixed bed-arc method, which uses the high temperature generated by the arc to heat the calcium oxide and needle coke in the calcium carbide furnace to above 2000°C, and stays for a certain perio...
