Comprehensive pipe gallery long-distance ventilation interval and ventilation method thereof
The invention relates to a comprehensive pipe gallery long-distance ventilation interval. The comprehensive pipe gallery long-distance ventilation interval comprises an air inlet, an air outlet and aventilation interval section located between the air inlet and the air outlet; and a plurality of jet fans are arranged at the top of the ventilation interval section, the jet fans are installed at the top of the comprehensive pipe gallery ventilation interval section, each jet fan carries a comprehensive pipe gallery environment monitoring module, and the exhaust air rate of the jet fans is dynamically controlled in real time according to the environment data. On the premise that an original ventilation opening design scheme is not changed, the ventilation interval length is obviously increased, the number of ventilation openings is reduced, and therefore the construction cost is obviously reduced; the jet fans effectively make up the loss of an airflow pressure head caused by lengtheningof the ventilation interval; and the ventilation interval is wide in application condition, and has good applicability, good ventilation and good smoke exhaust effect under normal ventilation and emergency conditions.
本发明涉及一种综合管廊长距离通风区间，所述综合管廊长距离通风区间包括进风口、出风口，以及位于进风口和出风口之间的通风区间段；所述通风区间段的顶部设有若干射流风机，所述射流风机安装于综合管廊通风区间段顶部，每一射流风机均搭载综合管廊环境监测模块，根据环境数据实时动态控制该射流风机的排风量。本发明在不改变原有通风口设计方案的前提下，明显增大通风区间长度，减少通风口数量，从而显著降低工程造价。射流风机有效弥补了由于通风区间加长所造成的气流压头损失。本发明适用条件广，在正常通风和应急状态下，均具有较好的适用性、良好的通风和排烟效果。
