Comprehensive pipe gallery ventilation system crossing multiple fire partitions
A comprehensive pipe gallery ventilation system crossing multiple fireproof partitions comprises a fireproof wall, an air inlet shaft and an air exhaust shaft. Dividing the interior of the comprehensive pipe gallery into a plurality of ventilation subareas; a plurality of fireproof partitions are spanned in each ventilation partition; an air inlet shaft and an exhaust shaft are arranged at the two ends of each ventilation subarea, at least two exhaust fans communicated with the comprehensive pipe gallery through normally-open fireproof valves are arranged in each exhaust shaft, and the two exhaust fans are separated in the two different ventilation subareas through an exhaust shaft fireproof wall with a normally-closed fireproof door. At least two air inlet fans communicated with the comprehensive pipe gallery through normally-open fireproof valves are arranged in the air inlet shaft side by side, an air inlet shaft firewall with a normally-closed fireproof door separates the two air inlet fans in two different ventilation subareas, and an independent ventilation subarea is arranged between the air inlet shaft firewall and the air outlet shaft firewall. At least one middle firewall provided with a normally-open fireproof door and a normally-open fireproof valve is arranged in the ventilation partition, and a fireproof partition is formed between the middle firewall and the air inlet shaft firewall and between the middle firewall and the air outlet shaft firewall respectively. The distance between the air shafts is increased, and the number of the air shafts is reduced.
一种跨越多防火分隔的综合管廊通风系统，包括防火墙、进风井、排风井；将综合管廊内划分出多个通风分区；每一个通风分区内跨越多个防火分隔；通风分区的两端部设置进、排风井，排风井内设置至少两台通过常开防火阀连通综合管廊的排风机，带有常闭防火门的排风井防火墙将两台排风机隔开在两个不同通风分区里，进风井内并排设置至少两台通过常开防火阀连通综合管廊的进风机，带有常闭防火门的进风井防火墙将两台进风机隔开在两个不同通风分区里，进、排风井防火墙之间为一个独立的通风分区；在通风分区内至少设置一个设有常开防火门及常开防火阀的中间防火墙，与进、排风井防火墙之间分别构成一个防火分隔。本发明加大风井间距减少风井数量。
