Stay cable dehumidification system and stay cable dehumidification method

Abstract

The invention discloses a stay cable dehumidification system and a stay cable dehumidification method. The stay cable dehumidification system comprises a dehumidification module as well as a stay cable ventilation module which is used to convey new air processed by the dehumidification module to a stay cable. The dehumidification module comprises a filter device, a dehumidification device, a dry air balance device and a gas conveying device, wherein the filter device is used to filter the input new air; the dehumidification device is used to dehumidify the new air filtered by the filter device; the dry wind balance device is used for gas pressure balance of the new air dehumidified by the dehumidification device; and the gas conveying device is used to make the new air be conveyed to the filter device, the dehumidification device and the dry wind balance device in succession. According to the stay cable dehumidification system and the stay cable dehumidification method provided by the invention, dry wind is conveyed to the stay cable by the dehumidification system, so that dehumidification and corrosion prevention can be achieved; the system can be detected in time; corrosion problems of upper and lower anchor heads and the stay cable are solved; replacement frequency of the stay cable is greatly reduced; and bridge safety is enhanced effectively.

Description

Technical field [0001] The invention relates to the field of stayed cable dehumidification, in particular to a stayed cable dehumidification system and a stayed cable dehumidification method. Background technique [0002] Due to the corrosion problem of the existing stay cables, especially in areas with high humidity, the upper and lower anchor heads of the stay cables are easily corroded due to the influence of rainwater and various corrosive gases, so regular oil filling and cable replacement are required. Such maintenance has caused problems of high maintenance cost and long repair time. Some cable-stayed bridges have higher maintenance costs than their construction costs, and cable-stayed bridges have a short life span, posing safety risks. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a stay cable dehumidification system, which can solve the problems of stay cable corrosion and high...
