Abstract

The invention relates to a production device for a calcium carbide co-production coking product. The production device comprises a lime kiln, a calcium carbide furnace, a carbonization chamber, coking product separation equipment, hydrogen separation equipment and hydrogenation equipment, wherein a lime outlet is connected with a feed port of the carbonization chamber; a coke outlet of the carbonization chamber is connected with an inlet of the calcium carbide furnace; a coking product outlet of the carbonization chamber and a gas outlet of the calcium carbide furnace are connected to the coking product separation equipment; a gas outlet of the coking product separation equipment is connected to the hydrogen separation equipment, and a liquid outlet is connected to the hydrogenation equipment; a hydrogen outlet of the hydrogen separation equipment is connected to the hydrogenation equipment. A discharge port of the hydrogenation equipment is connected to a product storage tank; and a fuel outlet of the hydrogen separation equipment is connected to a fuel burner of a lime kiln calcining zone. The production device is combined with the lime kiln and carbonization equipment through the calcium carbide furnace, and production of the calcium carbide co-production coking product is realized, so that the transportation cost is saved, the energy is effectively utilized, resource is saved, the production cost of calcium carbide and coking product is reduced, and the economic benefit of the enterprise is increased.

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...
