Abstract
The invention discloses a blowing mechanism for an exhaust system of a submerged arc furnace, and the blowing mechanism is characterized in that a motor is connected with a decelerator and fixed to the upper surface of a bearing shell. The blowing mechanism downwardly passes through an upper bearing and a nitrogen gas seal device by a coupler for the decelerator sequentially and is connected to a rotating shaft, and the lower end of the rotating shaft is connected with the lower bearing below a tank. The upper part of the upper box is tightened with the lower part of the bearing by bolts, and the lower end of the upper box is connected with the upper part of the dust remover tank of the lower box by bolts. The upper part of a rotary cylinder is tightened with a rotating shaft by rib plate. The upper side of the upper box is provided with an air inlet pipeline, an air outlet device is arranged below the side of the rotary cylinder, and the lower part of the dust remover tank is provided with a dust remover cloth bag. The blowing mechanism has the following technical and economic effect: the cloth bag is blown by purified furnace gas to avoid to reduce heat value of the purified furnace gas so as to obviously improve the quality of the purified furnace gas. The previous nitrogen production equipment specifically configured to blow nitrogen is cancelled so as to reduce enterprise cost and energy consumption, thus the blowing mechanism has the popularization and promotion value.
