A full-flow heat energy recovery centrifugal compressor
By setting a hollow cover at the impeller outlet to form a gas retention heat exchange chamber with the rotating impeller, and combining it with a variable cross-section flow channel and an elastic flaring mechanism, the problems of low heat recovery efficiency and poor adaptability to changing operating conditions at the impeller outlet of traditional centrifugal compressors are solved. This achieves a balance between high-efficiency heat exchange at full flow rate and aerodynamic performance, and improves the operational stability and reliability of the equipment.

AI Technical Summary
Traditional centrifugal compressors have low heat recovery efficiency at the impeller outlet, making it impossible to achieve full-flow heat exchange. Furthermore, they struggle to balance aerodynamic performance and reliability under varying operating conditions, resulting in problems such as insufficient heat exchange, inadequate structural strength, and increased vibration.
A hollow cover is installed at the impeller outlet to form a closed gas retention heat exchange chamber with the rotating impeller. Forced full-flow heat exchange is achieved through the exhaust channel, and airflow is controlled by a variable cross-section flow channel and an elastic flaring mechanism to ensure sufficient heat exchange and a balance of aerodynamic performance under different operating conditions.
It achieves full-flow, high-efficiency heat recovery, improves heat exchange efficiency and aerodynamic performance, reduces equipment processing costs and operating risks, and enhances the equipment's adaptability and stability under varying operating conditions.
