Abstract
The utility model discloses an air outlet device for forming an air curtain for a sintering ignition furnace. The air outlet device comprises an air pipe, wherein one end of the air pipe is closed, one opening end of the air pipe is provided with an air fan, the side all of the air pipe is provided with a plurality of parallel through holes, each through hole is respectively connected with a steel pipe, and the other end of each steel pipe is provided with a spray nozzle. By adopting the structure, the air curtain is formed between the ignition furnace and a preheating furnace, and the heat conduction between an ignition section and a heat insulation section is reduced. Meanwhile, a large amount of air enters the ignition furnace, and then the oxygen content in a furnace hearth is supplemented, so the combustion of gas in the ignition furnace is more sufficient.
