Fire-fighting exhaust exit passageway system for house buildings
The invention relates to the technical field of smoke exhaust devices in house buildings, in particular to a fire-fighting exhaust exit passageway system for house buildings, which is more environment-friendly and can better work together with pipelines for communication to prevent bad air return. The fire-fighting exhaust exit passageway system comprises a vent pipe, wherein a plurality of through holes are longitudinally formed in the side wall of the vent pipe, and the top of the vent pipe is open; the fire-fighting exhaust exit passageway system further comprises an air inlet pipe and a gas purification tank, wherein a non-return valve is arranged at the communicating part of the air inlet pipe and the vent pipe; a guide pipe is arranged at and communicated with the air outlet of the vent pipe, an air outlet pipe is arranged at the output end of the gas purification tank, an air pump is arranged on the guide pipe, and a gas outlet valve is arranged on the air outlet pipe; and the fire-fighting exhaust exit passageway system further comprises a plurality of first communicating pipes, a plurality of second communicating pipes and a plurality of sleeves, and an exhaust fan is arranged on each second communicating pipe.
