Steam cycle generator with solar heat collector and spiral heat regenerator

Abstract

The invention discloses a steam cycle generator with a solar heat collector and a spiral heat regenerator. The steam cycle generator is composed of a heat collecting device, a water pump, a spiral heat regenerator, a condenser, a solar heat collector, a generator and a steam turbine. A power generation mode based on a solar heat effect based on steam circulation is adopted, the integrated solar heat collector is used for collecting light energy, and the solar heat collector is used for gathering hot-gas to provide heat energy for a solar power generation system. The sphere center of a hemispherical spherical reflector of the solar heat collector is located on a heating layer of a shell, and heat is absorbed by a heat absorption plate to increase the heat exchange distance to strengthen heat exchange; the solar heat collector has the characteristics of good condensation effect and light weight. When the fluid in the spiral heat regenerator passes through a spiral structure, and the fluid flows in a spiral channel, so that the heat exchange distance is prolonged; the heat exchange is enhanced by the heat exchange between the two surfaces of the heat absorption plate, the spiral heatregenerator does not generate flow loss caused by separation of a boundary layer, the high utilization heat of the generator is realized, and the power generation efficiency of the generator is improved.

Description

technical field [0001] The invention relates to a steam cycle power generation device, in particular to a steam cycle generator with a solar heat collector and a spiral regenerator. Background technique [0002] Social and economic development and progress require energy support, and the energy supply is mainly based on disposable fossil fuels. Nowadays, fossil fuels are increasingly scarce and environmental pollution is becoming more and more serious. Research on renewable, clean, and environmentally friendly green energy that can replace disposable energy, In particular, the application of clean energy power generation has become unstoppable. As clean energy, wind energy and solar energy have always been valued by the user market and the country's future energy strategy. However, there has been a lack of multi-energy combination products that are truly popular and meet multiple needs in the market. The emergence of wind-solar combined power generation system will improve ...

Problems solved by technology

[0004] In terms of focusing on solar energy, the traditional solar steam engine power generation methods mainly include trough type and tower type. The metal square plate air regenerator used in the invention patent CN106870199A "A Wind-solar Combined Generator" has low heat exchange efficiency, which limits Rotational effect of the Stirling machine

Invention patent CN200710175970.5 "Tower solar thermal power generation system with two-stage heat storage" uses a tower heat collection array, which can ensure a large degree of light energy collection, but occupies a large area and disperses sunlight. It is difficult to debug and maintain the reflector in the later stage, and the comprehensive economic benefit is not high
