一种隧道救援车用大风量过滤通风系统
摘要：
一种隧道救援车用大风量过滤通风系统，属于消防技术领域的集体防护系统，主要由由风机、烟雾过滤器、流量计、电动密闭阀、滤毒器、通风管道和控制装置等组成。本发明使用时可根据污染物的种类，系统通过控制装置转换不同工作方式；烟雾过滤器过滤各种颗粒物；滤毒器可过滤有毒有害气体或蒸气，可防止有害及污染气体在隧道聚集，防止隧道中的污染物对隧道内、外的人员造成伤害，以便于及时救援与恢复隧道正常通行。
摘要（英）：

The invention provides a large-air-volume filtration ventilation system for a tunnel rescue vehicle and belongs to a collective protection system in the technical field of fire protection. The large-air-volume filtration ventilation system mainly consists of a fan, a smoke filter, a flow meter, an electric closed valve, a poison filter, a ventilation duct, a control device and the like. When the large-air-volume filtration ventilation system is used, different working modes of the system can be switched through the control device according to pollutant varieties. The smoke filter filters various particulate matter. The poison filter can filter poisonous and hazardous gas or steam and can prevent harmful and polluted gas from being gathered in a tunnel and prevent pollutants in the tunnel from harming persons inside and outside the tunnel so as to facilitate timely rescue and normal passing recovery of the tunnel.
