<p>A high-speed tunnel fan including a hexagonal pipe type electrostatic filter is provided to collect smoke, pollutants and fine dust in a tunnel with high collecting efficiency and to discharge the purified air to the outside of the tunnel. A hexagonal pipe type electrostatic filter is coupled to the front or the rear of the high-speed tunnel fan in parallel, wherein many hexagonal pipes of the hexagonal pipe type electrostatic filter collect dust without interfering with air flow and to purify the polluted air in a tunnel. The hexagonal pipe type electrostatic filter contains a hexagonal pipe assembly formed by coupling many hexagonal pipes in a row and located in parallel to the high-speed tunnel fan, a rotary projection plate(20) provided with projections and connections, formed in a twist structure to supply centrifugal force to collection objects and inserted to each hexagonal pipe, a power supply support located on the front and the rear of the hexagonal pipe assembly and coupled with the connections of the rotary projection plate exposed from the hexagonal pipes to fix the rotary projection plate and to connect with a high voltage supply device electrically, and a collecting housing provided with a fixture to couple with the front or rear of an outer case of the high-speed tunnel fan and an insulating mold at an internal wall in the cylindrical shape and including the hexagonal pipe assembly.</p> |
