Description

Technical Field

[0001] The utility model belongs to the technical field of steel box girder dehumidification systems, in particular to a maintenance-free steel box girder dehumidification system dust removal device. Background Art

[0002] The main reason for the unstable operation of the steel box girder dehumidification system is the untimely maintenance of the filtering device, which leads to the failure of anti-corrosion. Corrosion will affect the structural life and structural safety of the bridge steel. At present, the steel box girder dehumidification system mainly adopts a rotary dehumidifier, and its regeneration process requires the introduction of air from the outside. The air cleanliness is poor and the maintenance requirements of the filter are high. If the equipment is blocked and the dehumidification fails, it will not only affect the bridge steel, but in severe cases it will cause damage to electrical equipment. Utility Model Content
