AI Technical Summary

Technical Problem

The existing air compressor cooling circulation device requires the air compressor to continue running when the main generator set of the power station is shut down, resulting in the direct discharge of residual exhaust pressure and waste. In addition, the pipeline lacks the ability to adapt to ambient temperature, which leads to freezing damage to the circulating water pump and insufficient heat dissipation of the heat exchanger. The overall operational reliability and environmental adaptability cannot meet the requirements of extreme working conditions.

Method used

A vortex tube is used for cold and heat separation. The residual pressure of the air compressor exhaust drives the vortex tube for cold and heat separation. The cold air is used to cool the water tank, and the hot air is used for heating the circulating water pump and heat exchanger. Combined with a magnetic stirring mechanism and redundant dual pump design, energy cascade utilization and water temperature balance are achieved. A passive visual indicator mechanism is added for adaptive adjustment.

Benefits of technology

It enables the cascade utilization of exhaust energy under power failure conditions, reduces system energy consumption, improves operational reliability and low-temperature adaptability, ensures the intuitiveness and reliability of inspection, avoids the risk of mechanical seal leakage and freezing damage, and enhances the system's environmental adaptability.
