Abstract

The invention discloses a solar heat absorber capable of being driven to rotate and translate through wind power and a working method thereof. The solar heat absorber capable of being driven to rotateand translate through the wind power comprises a rack, a cavity heat absorber, a wind turbine unit, a direct current motor, a storage battery pack and a controller, wherein the cavity heat absorber comprises a heat insulation cavity, a heat absorption body, a hot working medium collecting cavity and a cold working medium collecting cavity, the heat insulation cavity is of a cylindrical structureand is fixedly mounted on the rack, the heat absorption body comprises a cylindrical heat absorption cavity and a working medium transport shaft, the working medium transport shaft is installed on a heat absorption cavity bottom plate and is coaxial with the heat absorption cavity, the heat absorption cavity is installed in the heat insulation cavity, the working medium transport shaft penetratesout of a through hole in the heat insulation cavity bottom plate, and the heat absorption cavity can rotate and translate relative to the heat insulation cavity. The solar heat absorber not only realizes the rotation and reciprocating translation of the solar cavity heat absorber, but also realizes the power supply driving of stored electricity of the wind generating set when no wind exists or wind power is insufficient, and wind energy can be converted into electric energy and stored.

Description

Technical field [0001] The invention relates to the field of solar light and heat utilization, in particular to a solar heat absorber driven by wind energy to rotate and translate and a working method thereof. Background technique [0002] Solar energy is a clean, environmentally friendly and widely distributed renewable energy. Solar thermal power generation (CSP) technology is one of the important ways to efficiently develop and utilize solar energy. CSP technology has three typical methods: trough type, dish type and tower type. The latter two types can achieve high-temperature operation (usually above 600°C), so their light-heat-electric conversion efficiency is the highest. Dish and tower systems usually use large-area concentrators to gather solar radiation energy on the receiver (or heat sink), and then heat the fluid working medium inside the receiver, and then drive the heat engine to do work through the thermal cycle process , And drive the generator set to generate po...

AI Technical Summary

Problems solved by technology

However, the heat absorber in the prior art only realizes the rotational movement along the circumferential direction, but the movement along the axial direction does not realize

This cannot solve the problem of non-uniform energy flow along the axial direction

In fact, the non-uniformity of the energy flow distribution along the axial depth direction of the cavity receiver is more significant. The distribution is uniform, but exhibits a high degree of non-uniformity along the height of the cavity

In addition, the rotation process of the heat absorber in the prior art needs to consume high-grade electric energy in the power grid, and the rotation of the heat absorber (usually a metal tube) is likely to cause the leakage of the working fluid, which need to be solved urgently
