The present invention relates to a multi-stage venting and recovery integrated system for supercritical CO2 Brayton cycle. The system includes the following components: an intake subsystem, which is used to provide an exhaust source; a multi-stage venting subsystem, which is connected to the outlet side of the intake subsystem and used to relieve the exhaust pressure of the intake subsystem to Safety range; recovery subsystem, connected to the air outlet side of the air intake subsystem, used to store the air out of the air intake subsystem when it needs to be stored or not allowed to be discharged; automatic control subsystem, used for the intake air The subsystem, multi-stage venting subsystem, and recovery subsystem are automatically controlled to realize the automatic work of gas decompression and efflux or recovery and storage. The invention solves the problems of preventing the generation and blockage of dry ice in the venting process of multiple working conditions in the supercritical CO 2 Brayton cycle, and reusing the heat during the recovery process, and provides a multi-stage reducing The integrated control system of pressure venting and recovery. |
