Civil air defense project ventilation system

Abstract

The invention relates to a civil air defense project ventilation system comprising a door frame and a door body arranged in the door frame and further comprising a first air inlet pipe. A suction ventilator is connected to the end, located indoors, of the first air inlet pipe. An air outlet pipe is connected to the air outlet end of the suction ventilator. A filtration box and a detection sectionare arranged between the first air inlet pipe and the suction ventilator sequentially. A second air inlet pipe communicates with the first air inlet pipe. A third valve and a purifier are connected between the second air inlet pipe and the suction ventilator sequentially. During use, an external power source is connected, the suction ventilator is driven, at the moment the first air inlet pipe sucks outdoor air to the interior, the sucked-in air passes through the filtration box first and is then detected so as to judge whether the air contains harmful gas, if yes, the air is introduced into the purifier to be purified, and thus the air entering the interior is not liable to injure human bodies. The civil air defense project ventilation system has the effects that when outside air is poorin quality, the quality of the air entering the interior can still be ensured.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a ventilation system for civil air defense engineering. Background technique [0002] Civil defense is also known as civil defense. Civil defense is an international general term. It is an activity in which the government mobilizes and organizes the masses, adopts anti-aircraft raids, disaster relief measures, implements rescue operations, prevents and mitigates disaster hazards. Civil defense doors are civil defense protection equipment. Meet the protection and sealing function requirements. Among the many types of civil air defense doors, steel structure civil air defense doors are widely used, and the control form of its opening and closing is mainly manual control, that is, civil air defense doors are manual doors. [0003] The civil air defense door is a necessary facility for preventing and mitigating disaster hazards. In case of a long-term situation...

AI Technical Summary

Problems solved by technology

[0003] The civil air defense door is a necessary facility for preventing and mitigating disaster hazards. In case of a long-term situation, it will be used for a long time. Therefore, it is necessary to set up necessary ventilation devices. At present, the common civil air defense ventilation devices However, in wartime, the external environment may be relatively poor, which will lead to poor air quality entering the room, which will affect the health of the people in the room
