ELECTRIC ARC FURNACE DUST RECYCLING APPARATUS AND METHOD |
摘要 |
The present technology provides an illustrative apparatus for recycle electric arc furnace (EAF) dust and method of use related to the same. The apparatus has a heat controlling region coupled to a separation volume and includes at least one magnet and a cooling region. The heating controlling region operates at a temperature sufficient to transform at least some of the EAF dust into a mixture of gaseous zinc and one or more additional metals. The magnet separates the iron-rich material from the mixture of gaseous zinc and one or more additional metals and the cooling region condenses the gaseous zinc. |

1. An apparatus for recycling electric arc furnace (EAF) dust material, the apparatus comprising:
a heat controlling region configured to control a temperature of EAF dust material within the heat controlling region such that the temperature of the EAF dust material is sufficient to transform at least a portion of the EAF dust material into a mixture of gaseous zinc and one or more additional metals, wherein the one or more additional metals comprise iron-rich material and steel additives; and a separation volume coupled to the heat controlling region and configured to receive the mixture of gaseous zinc and one or more additional metals, wherein the separation volume comprises:
a separation unit configured to separate within the separation volume the iron-rich material from the mixture of gaseous zinc and one or more additional metals;a passage configured to direct the gaseous zinc to a cooling region; anda cooling region configured to condense the gaseous zinc within the cooling region after the iron-rich material is separated, and wherein the condensing the gaseous zinc comprises condensing zinc oxide into different grades that fall out at different locations within the separation unit. |
