Abstract

The invention discloses a disk solar thermoelectric generator which comprises a heliostat system, a condenser, a receiver, a high temperature heat storage tank and a working medium phase change engine, wherein sun is tracked by the heliostat system in real time; sunlight is reflected on the receiver by the condenser; high heat flux radiant energy reflected from the condenser is absorbed by the receiver positioned on a support, is transformed into high temperature heat of working fluid, and is stored in a heat transfer fused-salt medium in the high temperature heat storage tank; the working medium in the working medium phase change engine is heated by the high temperature fused-salt medium to drive the working medium phase change engine to rotate and make the generator generate electricity, and the heat energy is transformed into mechanical energy. The invention has the advantages of low cost, reasonable design, simple structure and high work efficiency, and has the characteristics of no exhaust emission, oil and coal replacement, no environmental pollution and low carbon.

Description

technical field [0001] The invention relates to a dish type solar thermal power generator, which is used in the occasion of small solar power generation. Background technique [0002] At present, the reserves of oil and coal are limited, the price rises, and the CO produced by burning oil and coal as fuel 2 , SO 2 It is very harmful to the environment and endangers the survival of human beings. The use of solar power to generate electricity without exhaust emissions is the direction of energy development in the 21st century. Tower-type solar power generation costs high, requires a lot of investment, and occupies a large area, so it cannot be widely used. Dish-type solar thermal power generation has small size, low cost, good reliability, and high power generation efficiency. It can be widely used in rural areas, small businesses, and individual families. It has great development potential and application prospects. Contents of the invention [0003] In order to solve t...
