Air dust collection purification device installed at the external exhaust ventilation in the subway tunnel

摘要

The present invention relates to a ventilation hole buried type filter dust purification device installed in an external exhaust ventilation hole of a subway. For this purpose, the present invention is assembled and installed inside the external exhaust vent 30 of the subway, the frame 140 moves up and down along the skid guide rail 160, and the external exhaust vent 30 of the subway By using the exterior exhaust vent 30 wall surface of the subway as it is without a separate outer case and reducing the weight, only the upper part of the filter can be replaced, so that the convenience and economy of maintenance can be increased, and the It is characterized in that it facilitates mass production through modularization and standardization to promote installation convenience, work safety, uniformity of quality, and economic feasibility. The present invention configured as described above uses the wall surface of the external exhaust vent without a separate outer case and reduces the weight so that only the upper part of the filter can be replaced, thereby increasing the convenience and economic feasibility of maintenance and repair. By using the ventilation device together, the quality and reliability of the ventilation hole-mounted filter dust filter can be greatly improved, so that the various needs (needs) of the users and consumers can be satisfied and a good image can be planted.
