The present invention includes a storage chamber that has an inner space where a raw material is accommodated; a dust collection unit that suctions dust and gas which is scattered from the storage chamber; a dust collector that is connected to the dust collection unit to generate a suctioning force; a water seal duct that is disposed between the dust collection unit and the dust collector and has an inner space where a liquid is accommodated; and a liquid discharge unit that is connected to the water seal duct and communicates with the inner space of the water seal duct. According to embodiments of the present invention, the liquid discharge unit that is disposed in a lower portion of the water seal duct is provided to discharge the liquid overflowing in the water seal duct. Accordingly, the overflowing liquid can be automatically discharged outside before flowing into the dust collector through the liquid discharge unit due to the suctioning force of the dust collector. As such, an accident that the liquid in the water seal duct flows into the dust collector to inhibit dust collection can be prevented, and thus the contamination of working environments caused by the impossibility of dust collection can be prevented. Also, the lifetime of a back filter can be lengthened because the inflow of the liquid in the water seal duct into the dust collector back filter can be prevented. Accordingly, the life of the facility is also lengthened for higher operation efficiency and lower facility repair and maintenance costs. |
