Cooling structure of water vapor compressor and water vapor compressor

By designing a cooling groove on the exhaust bearing housing of a steam compressor, cooling water is used to remove heat from the high-temperature zone and reintroduce it into the intake port, thus solving the problems of bearing material degradation and energy waste, and achieving efficient waste heat utilization and energy efficiency improvement.

AI Technical Summary

Technical Problem

The exhaust bearings of existing steam compressors are subjected to high temperature and high pressure conditions for a long time, which leads to material degradation and shortened service life. In addition, the existing cooling schemes fail to effectively recover high-temperature waste heat, resulting in energy waste and low heat dissipation efficiency.

Method used

A cooling groove is designed on the bearing housing at the exhaust end. Cooling water carries away the heat from the high-temperature zone and re-inputs it into the intake port for compression. Combined with the natural separation of the air and water paths, the waste heat in the high-temperature zone is reused.

Benefits of technology

This improved the service life of bearings and the operational reliability of steam compressors, enhanced energy efficiency, and enabled the secondary utilization of waste heat in high-temperature zones and the cascade utilization of energy.
