Abstract

The invention relates to a calcium carbide furnace with combination of an oxygen heating method and an electric heating method, which adopts the structure of an electric-arc furnace, and comprises a furnace body, a furnace cover, a feed inlet and a calcium carbide furnace gas outlet, wherein 1-5 electrode assemblies are arranged on the calcium carbide furnace and penetrate the furnace cover to be inserted into the furnace body; each electrode assembly is of a sleeve structure, and comprises an inner sleeve and an outer sleeve; an electrode is accommodated in each inner sleeve; a conduction oil jacket is arranged between the inner sleeve and the outer sleeve of each electrode assembly; a fuel spray pipe, an oxygen spray pipe and a calcium carbide extraction pipe are arranged in each electrode; a conduction oil inlet and a conduction oil outlet are arranged on each conduction oil jacket, and are connected with a conduction oil circulation system. According to the calcium carbide furnace, the oxygen heating method and the electric heating method are combined, so that the electric consumption of calcium carbide production is lowered, the cost is saved, the quality of a calcium carbide product is ensured, and the economic efficiency of an enterprise is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical production equipment, and relates to a calcium carbide furnace, in particular to a calcium carbide furnace combined with oxygen and electricity. 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. In particular, the price increase of petroleum products has stimulated the development of calcium carbide industry. [0003] The production methods of calcium carbide are mainly aerobic thermal method and electrothermal method. In industry, electrothermal method is generally used to produce calcium carbide. The electrothermal method is to smelt coke and calcium oxide in an electric fu...
