Abstract

The invention relates to a production device for coproduction of calcium carbide by an electrothermal method and an oxygen thermal method. The production device comprises an oxygen thermal method calcium carbide furnace, an electrothermal method calcium carbide furnace, a semi-coke furnace, a lime kiln and a power generation system. A coal briquette preparation system is connected to the semi-coke furnace through a coal briquette preheater, and the semi-coke furnace is connected to the electrothermal method calcium carbide furnace and the oxygen thermal method calcium carbide furnace. A limestone supply device is connected to the lime kiln through a limestone preheater, and the lime kiln is connected to the electrothermal method calcium carbide furnace and the oxygen thermal method calcium carbide furnace. Calcium carbide furnace gas outlets of the calcium carbide furnaces are connected to a fuel inlet of the semi-coke furnace, a semi-coke tail gas outlet of the semi-coke furnace is connected to the fuel inlet of the lime kiln and the fuel inlet of a steam boiler, and a waste heat boiler is connected to a steam turbine. A power generator set is connected to the wiring end of the electrothermal method calcium carbide furnace through a power transmission device. The production device provided by the invention fully utilizes byproducts and waste heat of the calcium carbide furnaces and the semi-coke furnace, reduces the energy consumption and the calcium carbide production cost and improves the comprehensive economic benefits of an enterprise by combining the oxygen thermal method calcium carbide furnace and the electrothermal method calcium carbide furnace with the semi-coke furnace, the lime kiln and the power generation system.

Description

Technical field [0001] The invention belongs to the technical field of chemical production equipment, and relates to a calcium carbide production device, in particular to a production device for the combined production of calcium carbide by an electric heating method and an oxygen heating method. Background technique [0002] Calcium carbide is commonly known as calcium carbide. Calcium carbide reacts with water to form acetylene. Acetylene is an important chemical raw material, mainly used to produce polyvinyl chloride, vinyl acetate and acrylic-based products. More than 70% of my country's PVC products are derived from acetylene produced by calcium carbide. In particular, the price increase of petroleum products stimulated the development of the calcium carbide industry. [0003] Industrial calcium carbide production generally adopts the fixed bed-arc method, which uses the high temperature generated by the electric arc to heat the lime and coke (or blue charcoal) in the calcium...
