を良くして消煙効果の増大を図ったものである。The smoke elimination chamber 3 includes a vane 31 that disturbs the airflow sent from the intake duct 2, an aqueous solution spray nozzle 32 that sprays an aqueous solution spray stream that adsorbs smoke particles into the airflow, and a solution extraction port 33. Each of them is provided with a partition wall plate 34, and furthermore, an intake/exhaust fan 35 is provided on the exhaust tact 4 side of the smoke elimination chamber 3. As the aqueous solution supplied to the aqueous solution spray nozzle 32, in addition to water, it is also possible to use an aqueous surfactant solution that easily binds to smoke particles, and furthermore, by charging the mist droplets with a high voltage, etc., the smoke extinguishing effect can be further improved. - can be obtained. In addition, 35 intake/exhaust fans may be provided at arbitrary locations within the intake/exhaust ducts 2 and 4. The airflow stirring vanes 31 are designed to increase the residence time of the inhaled air in the smoke elimination chamber 3, improve the contact with the mist droplets, and increase the smoke elimination effect.

除去されているため、人命に係ることはない。Such a device is installed in advance in the ceiling of a hotel room, etc. that requires smoke exhaust, and is configured to operate in conjunction with a fire detector (not shown). When this is detected, the suction/exhaust fan 35 and the aqueous solution pump for smoke elimination and foaming (not shown) are driven 1, and the smoke generated by the fire is sucked in through the intake port 11 12, and the pull filter 21 deodorizes it in advance. Alternatively, the dust is adsorbed and sent to the smoke elimination chamber 3, where the smoke particles in the intake air are removed by mist droplets from the spray nozzle 32. The airflow from which smoke and the like have been removed is further passed through an exhaust duct 4 to a fire extinguishing foam 1.
0, and the coarse fire extinguishing foam is sent out into the room from foaming 1 to exhaust port 6. This coarse fire extinguishing foam is foamed by a solution with a high foaming rate, so that the room is immediately filled with foam. At this time, even if a person remains in the room, the smoke or toxic gas is removed by the smoke removal chamber 3 of this device, so there is no danger to human life.
