Nuclear energy and biomass energy association system method

Abstract

The invention provides a nuclear energy and biomass energy association system method, and relates to the field of nuclear power. The nuclear energy and biomass energy association system comprises a nuclear energy subsystem and a biomass energy subsystem. The nuclear energy subsystem comprises a reactor, a high-temperature heat exchanger, a steam generator and a main pump, wherein the reactor, the high-temperature heat exchanger, the steam generator and the main pump are sequentially connected in an end-to-end mode; the main pump is connected with the reactor; the steam generator is sequentially connected with a steam turbine, a low-temperature heat exchanger, a condenser and a secondary circuit pump in an end-to-end mode. The biomass energy subsystem comprises a biomass gasification reactor, a washing tower, a reforming tower, a Fischer-Tropsch synthesis tower, a refining tower and a rectifying tower, wherein the biomass gasification reactor, the washing tower, the reforming tower, the Fischer-Tropsch synthesis tower, the refining tower and the rectifying tower are sequentially connected in an end-to-end mode; the high-temperature heat exchanger is connected with the reforming tower, and the low-temperature heat exchanger is connected with the refining tower; the steam generator generates steam to push the steam turbine to drive a generator to generate electricity. Nuclear energy subcycle and biomass energy subcycle are repeated, and a high temperature gas cooled reactor and biomass preparation liquid fuel are coupled through energy distribution. Clean electricity and liquid fuel can be generated, and the demand for integration of electricity and liquid fuel is met.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a combined system and method of nuclear energy and biomass energy. Background technique [0002] Nuclear power generation and production process heat technology is a mature technology, and biomass energy preparation of liquid fuels has also been widely used in industry. At present, all countries in the world have carried out the research and development of small nuclear reactor technology, and its electric power is generally in the range of 100-300MW. The technology of using biomass gasification and Fischer-Tropsch synthesis to prepare liquid fuels has been industrially applied and demonstrated in the world. Processing about 1,000 tons of biomass every day requires about 20MW of energy, including heat and electricity. However, these two technologies are independently developed technologies, and there is no existing technology that can combine these two independent technologies into ...
