Since civil air defense basements have poor ventilation, are prone to moisture, and have poor exhaust effects, ventilation systems are often required in the construction of civil air defense projects. Since the external air contains more dust, it is necessary to filter and remove dust from the air circulating in the ventilation ducts. Since the air filter has a certain service life, it needs to be cleaned or replaced after long-term use. Since the air filter frame is fixed in the ventilation duct, it is dangerous and difficult to operate to disassemble and clean the air filter. For this reason, we proposed a ventilation filtration device based on civil air defense projects. Utility Model Content
