Vaporization power generation method for liquid nitrogen power regeneration recycling and power generation equipment for liquid nitrogen power regeneration recycling

Abstract

The invention discloses a vaporization power generation method for liquid nitrogen power regeneration recycling and power generation equipment for liquid nitrogen power regeneration recycling. The method comprises the steps that firstly, clean renewable energy power generation equipment is used to generate the electrical energy, and the source of the electrical energy is provided for nitrogen production and separation purification equipment, gas expansion liquefaction equipment, an air preheater, a high temperature heat exchanger, and gas heating equipment in the process of vaporization powergeneration; and then the nitrogen and the oxygen in the air are separated, purified and liquefied to obtain liquid nitrogen, the liquid nitrogen is supercharged, vaporized, pre-heated, and high-temperature heated to obtain the high temperature and high pressure gas to be sent into a steam turbine for expansion work to be converted into the mechanical energy to drive a generator to run to produce the electrical energy to be output. The invention belongs to a novel environmental-friendly power generation technology and has no pollution to the environment, the energy consumption is low, the consumption of the traditional energy is reduced, the method is not limited by the geographical environment, the construction cost is low, the source of raw materials is wide, the sustainable development is achieved, and the method can be applied and popularized in a large scale.

Description

technical field [0001] The invention relates to a power generation method and power generation equipment, in particular to a liquid nitrogen power regeneration recycling vaporization power generation method and power generation equipment, belonging to the technical field of power generation. Background technique [0002] With the continuous development of the economy, the demand for electric energy is also increasing. The existing power generation system is mainly divided into three major systems: thermal power generation, hydropower generation and wind power generation. The construction of hydropower generation is relatively difficult due to the limitation of many natural conditions such as water source and geographical environment. Although thermal power generation has low requirements on the geographical environment, it pollutes a lot, consumes a lot of energy, and the prospect of sustainable development is bleak. Although wind power generation is non-polluting and renew...

AI Technical Summary

Problems solved by technology

The existing power generation system is mainly divided into three major systems: thermal power generation, hydropower generation and wind power generation. Due to the limitation of many natural conditions such as water source and geographical environment, the construction of hydropower generation is relatively difficult.

Although thermal power generation has low requirements on the geographical environment, it pollutes a lot, consumes a lot of energy, and the prospect of sustainable development is bleak

Although wind power generation is non-polluting and renewable, it does not have the right wind anytime, anywhere, too big or too small, and the cost of building wind farms is also very high, making it difficult to apply on a large scale.
