Natural gas cabin ventilation system of building comprehensive pipe gallery

XU YUHANG

The invention discloses a natural gas cabin ventilation system of a building comprehensive pipe gallery. The system comprises an air inlet system and an air outlet system, the air inlet system is installed on the upper left side of a cabin body, the air inlet system comprises an air inlet structure, a first air distribution structure and a second air distribution structure, and the air outlet system is installed on the upper right side of the cabin body. The air outlet system comprises an air collecting structure and an air draft structure, the air outlet system and the air inlet system form a ventilation system of the cabin body, the air inlet main pipe is installed at the top of the cabin body, and the bottom of the air inlet main pipe is fixedly connected with the vertical pipe. According to the natural gas cabin ventilation system of the building comprehensive pipe gallery, the exhaust fan is started, air in the cabin body can be pumped into the air collecting opening and exhausted through the air outlet pipe and the air exhaust pipe in sequence, the air replacement work in the cabin body is completed, the replacement effect is sufficient, leaked natural gas can be exhausted, and the natural gas cabin ventilation system is high in practicability. The accident rate is lowered.
