Large titanium slag electric arc furnace flue dust collecting and cleaning device

The utility model discloses a flue dust collecting and cleaning device for a large titanium slag electric arc furnace, and particularly relates to the field of electric arc furnaces. The problems that much titanium concentrate is consumed along with smoke dust, part of materials are sintered in a pipeline, and a flue is blocked are solved. The electric furnace comprises an electric furnace body, a water-cooling flue and a collector, the flue above the electric furnace body is arranged in a Z shape, the collector is arranged at the lower corner of the electric furnace body, the collector can collect accumulated materials falling into the water-cooling flue, and the collector is provided with a discharging hole and can be opened regularly for discharging and cleaning. Titanium concentrate materials brought out by the smoke dust are prevented from being sintered in the flue to block the flue, and accumulated materials in the flue are prevented from falling into the electric furnace to form collapsed materials to
