Description
TECHNICAL FIELD

[0002] In tunnel engineering, the ventilation system is the key facility for guaranteeing the air quality in the tunnel, ensuring the driving safety and construction safety. The ventilation cylinder, as an important part of the ventilation system, mainly functions to introduce fresh air from outside into the tunnel and discharge the waste gas in the tunnel.
[0003] The conventional ventilation cylinder usually has a filter screen arranged inside for filtering the dust, impurities and pollutants in the air entering the tunnel, so as to reduce the pollution to the environment in the tunnel. However, the filter screen is prone to be blocked after being used for a period of time. The blocked filter screen not only reduces the ventilation efficiency and increases the energy consumption of the ventilation system, but also can cause poor ventilation, affect the air quality in the tunnel, and further endanger the driving safety and the health of the construction personnel. In order to clean the blocked filter screen, regular maintenance and cleaning by manual operation are usually required. This cleaning method not only has a large labor intensity, but also needs to consume a large amount of time and labor cost. In addition, the ventilation system can need to be temporarily stopped during the cleaning process, which will further affect the normal ventilation function of the tunnel.
[0004] Therefore, the utility model provides a tunnel ventilation cylinder with high -efficient filter mechanism. CONTENT OF THE UTILITY MODEL
