Abstract

The invention discloses carbon-thermal calcium carbide production equipment. The carbon-thermal calcium carbide production equipment comprises a thermal treatment section, a hot material conveying pipe and an oxygen thermal reduction section, wherein the thermal treatment section comprises a gas distributor, a raw material inlet and a hot material outlet; the gas distributor is arranged at the bottom part of an inner cavity of the thermal treatment section; the oxygen thermal reaction section comprises a hot material inlet, an oxygen spray nozzle, a tail gas outlet and a calcium carbide liquid outlet; the oxygen thermal reduction section is arranged under the thermal treatment section, the hot material outlet of the thermal treatment section is connected with the hot material inlet of the oxygen thermal reduction section through the hot material conveying pipe, and the tail gas outlet is connected with a high-temperature gas inlet. The carbon-thermal calcium carbide production equipment has the advantages that the material pyrolysis and the calcium carbide smelting are simultaneously completed; calcium carbide is produced by a hot material after pyrolysis, the oxygen consumption and coal consumption in the calcium carbide production process are decreased, the residual heat of tail gas of the calcium carbide is recycled and utilized, and the energy source utilization rate of the carbon-thermal calcium carbide production equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of calcium carbide production equipment, and in particular relates to a carbon-thermocalcium carbide production equipment which utilizes carbon-containing materials to produce calcium carbide. Background technique [0002] The production methods of calcium carbide include aerobic thermal method and electrothermal method. At present, electrothermal method is generally used in industry to produce calcium carbide, that is, coke (C) and calcium oxide (CaO) are melted and reacted in the calcium carbide furnace by using arc high temperature (> 2000 ℃) As for the generation of calcium carbide, the electrothermal method is characterized by the use of massive raw materials and the use of electric energy to produce calcium carbide. It has slow reaction rate, long reaction time, high reaction temperature, large power consumption, low calcium carbide output, and dust and tail gas control. difficult question. It is p...
