PURPOSE:To make the long term continuous operation of a humidifier possible by a structure wherein the waste water led from the humidifier to a cesspool is forcibly flushed toward the filter medium surface on the cesspool side so as to prevent flies and the like from easily adhering onto the filter medium surface. CONSTITUTION:The air in a factory is sucked in a humidifier 2 by means of a fanning device 3 and, after that, discharged in the factory. Said sucked air is humidified by the fresh water led from a fresh water tank 5 through a pipe 6. The excess water is separated by separating blades 8 and fallen down so as to be led through an advance passage 9 to a cesspool 10 in order to return to the fresh water tank 5 through a filter gauze 11. At that time, the waste water from the humidifier 2 is caused to collide against an inclined guide plate 13 so as to fall down along the filter gauze surface in the cesspool. Consequently, the time required for the filter gauze to become clogged by flies and the like is made longer, resulting in enabling to realize the long term continuous operation of the humidifier. |
