[0002] Tunnel ventilators are devices used for air circulation and removal of harmful gases in tunnels. Their working principle is to drive the rotor to rotate through an electric motor. The rotor blades inhale air and propel it axially. At the same time, under the action of centrifugal force, the air is accelerated to flow toward the tunnel exit, thereby forming a negative pressure area and discharging the air in the tunnel to the outside of the tunnel. Tunnel ventilators can generate a certain wind pressure and flow rate to discharge the dirty air and smoke in the tunnel, and at the same time introduce fresh air into the tunnel to ensure the freshness and safety of the air in the tunnel.
[0003] A tunnel ventilator is disclosed in the patent with application number 202223164419.X. Personnel can directly release the fixation of the locking assembly by toggling the assembly, thereby easily completing the disassembly of the mesh cover structure, and no additional tools are required, the operation can be completed by hand, which brings convenience to personnel; in combination with the above application, when using the existing tunnel ventilator, due to the polluted air in the tunnel, during the ventilation process, impurities and dust in the gas are easily discharged together, which affects the air quality and reduces the practicality of the device.

When the tunnel ventilator in the application is used, a filter box 200 is installed at one end of the ventilation cylinder 100 located at the air inlet. When ventilation is performed through the device, air is sucked in from one end of the air inlet through negative pressure, and the sucked gas enters the activated carbon chamber 206 through the filter inlet 202. When the gas enters the activated carbon chamber 206, the activated carbon filled in the activated carbon chamber 206 filters and adsorbs the gas, thereby filtering and adsorbing impurities and dust in the gas.
