Abstract

The invention discloses a simulation test bench for a closed Brayton circulating power generation system. The simulation test bench comprises a test piece, a heater and a cooler; a heater exhaust portcommunicates with a turbine inlet in the test piece through a pipeline; a heater gas inlet communicates with a heat regenerator hot end outlet in the test piece through a pipeline; the heat regenerator hot end outlet in the test piece communicates with a cooler gas working medium inlet through a pipeline, a cooler gas working medium outlet communicates with a gas compressor inlet in the test piece through a pipeline, and thus a closed gas loop is formed; and a vacuum pump communicates with a gas flow channel in a heater body through a vacuum pipeline and is used for vacuumizing the formed closed gas loop. The heater adopts an electromagnetic induction graphite heat-storage type heater, the simulation temperature can be effectively increased, the heater can work continuously and uninterruptedly for a long time, the temperature of the working medium with residual heat is decreased to the normal temperature through the cooler, and thus it is ensured that the working medium can circulatesmoothly.

Description

technical field [0001] The invention relates to a ground simulation test bench, in particular to a high-temperature closed cycle power generation simulation test bench, which belongs to the technical field of ground equipment power generation tests. Background technique [0002] The closed Brayton cycle power generation simulation device is mainly used for the research of special turbine power generation technology in which the working fluid repeatedly participates in the cycle, and realizes the turbine power generation of the ground test equipment. There is only energy exchange with the outside world, no material exchange, so it can be applied in deep sea and space environments, and form a nuclear power generation system with space nuclear reactors to provide high-power, long-term power for space vehicles. The application prospect is very broad. [0003] At the end of 1999, the United States took the lead in conducting roadmap research on the fourth generation nuclear ener...
