Description

technical field [0001] The invention relates to the field of calcium carbide raw material production, in particular to a method and system for producing calcium carbide. Background technique [0002] Calcium carbide, commonly known as calcium carbide (CaC 2 ), known as the mother of organic synthesis before the middle of last century. At present, it is mainly used in the production of series products such as vinyl chloride, vinyl acetate and acrylic acid. Calcium carbide synthesis methods include aerobic thermal method and electrothermal method. The current calcium carbide production process adopts electrothermal method, using high temperature generated by electric arc to heat lump calcium oxide and lump coke in fixed bed (also known as moving bed or electric furnace) to 2000 Above ℃, stay for a certain period of time to generate molten calcium carbide. However, this method uses block raw materials (30-60mm), although it is beneficial to the discharge of CO, but the react...
