CONSTITUTION: A dust collection device for an electric furnace comprises a dust collection main body(10) and a fire-proof wall component(20). The dust collection main body includes a waste gas inlet port(11) and a waste gas outlet port(12). Waste gas flows in and out through the waste gas inlet port and the waste gas outlet port. The waste gas outlet port is formed with height different from the waste gas inlet port. The fire-proof wall component is mounted on a part facing the waste gas inlet port in the inside of the dust collection main body.</p> |
