Abstract

The invention discloses a calcium carbide smelting furnace. The furnace comprises a heat treatment section, a hot material conveying pipe and an oxygen thermal reduction section. The heat treatment section comprises a gas distributor, a raw material inlet and a hot material outlet. The gas distributor is arranged at the bottom of an inner cavity of the heat treatment section. The oxygen thermal reduction section comprises a hot material inlet, an oxygen nozzle, a tail gas outlet and a calcium carbide liquid outlet. The oxygen thermal reduction section is disposed below the heat treatment section, the hot material outlet of the heat treatment section is connected with a 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 calcium carbide smelting furnace achieves integration of material pyrolysis and calcium carbide smelting. Thermal-state materials obtained after pyrolysis are used for producing calcium carbide, oxygen consumption and coal consumption for producing calcium carbide are reduced, calcium carbide tail gas waste heat is recycled, and the energy utilization rate of the calcium carbide smelting furnace is increased.

Description

technical field [0001] The invention belongs to the technical field of calcium carbide production equipment, in particular to a calcium carbide smelting furnace integrating material pyrolysis and calcium carbide smelting. Background technique [0002] There are two production methods of calcium carbide: oxythermal method and electrothermal method. At present, electrothermal method is generally used to produce calcium carbide in industry, that is, coke (C) and calcium oxide (CaO) are melted and reacted at high temperature (>2000°C) in a calcium carbide furnace. To generate calcium carbide, the characteristics of electrothermal preparation of calcium carbide are the use of bulk raw materials and the use of electric energy to produce calcium carbide. It has the characteristics of slow reaction rate, long reaction time, high reaction temperature, large power consumption, low calcium carbide output, dust and exhaust gas treatment. difficult question. It is precisely because t...
