AI Technical Summary

Technical Problem

In high-temperature and high-humidity tunnel environments, the air compressor is prone to corrosion and performance degradation due to the compression and cooling of water vapor, and the humidity content of the air greatly increases the burden on the air compressor and shortens its service life.

Method used

A new device including a dehumidification device and a cooling device is designed for installation in the tunnel. The dehumidification device removes moisture from the air through two dehumidifiers. The cooling device reduces the air temperature through water-cooled circulation to ensure that the air inlet air from the air compressor reaches the set humidity and temperature.

Benefits of technology

Effectively remove moisture from the air, reduce the corrosion risk inside the air compressor, reduce the flow resistance of the air compressor, improve the working efficiency and service life, and improve the compression ratio and efficiency of the air compressor.
