A solar receiving device for a butterfly solar test bench

Abstract

The invention is a solar receiving device of a butterfly solar test bench, which includes a heat exchange chamber, a glass lens, a metal shell, a heat insulation layer, a fixing device and a preheating chamber. The solar receiving device has a plurality of symmetrically arranged working fluids The intake pipe enters the preheating chamber, and after preheating, enters the heat exchange chamber through the deflector. After being fully heated, it is sent to the Stirling generator and other power generation devices through the outlet pipe. On the one hand, the structural design of the solar receiver can use the waste heat of the heat insulation layer of the receiver to heat the working medium, which improves the utilization rate of solar energy; The thermal effect can effectively increase the temperature of the outlet air; in addition, the present invention can also effectively avoid the abnormal working condition where the temperature of the working medium at the outlet of the receiver is unstable; at the same time, the present invention can effectively solve the problem that the temperature of the sun spot is too high Phenomenon.

Description

technical field [0001] The invention belongs to the technical field of solar photothermal power generation, in particular to the design of a butterfly solar receiver, especially a solar receiving device for a butterfly solar test bench. Background technique [0002] With the continuous development of society, my country's energy demand continues to increase, and the consumption of fossil energy such as coal, oil, and natural gas increases rapidly year by year. Because these energy sources are non-renewable energy sources, and these energy sources will also produce carbon dioxide and nitrogen oxides during consumption, which seriously threatens the earth's environment. In recent years, my country's energy and environmental problems have become increasingly prominent. Under such an era background , the country continues to reform the energy structure and vigorously develop clean energy such as solar energy, wind energy, and tidal energy. [0003] As an inexhaustible clean ener...

Problems solved by technology

[0004] This patent researches butterfly solar energy. For the traditional butterfly solar energy receiving device, there are two main problems: (1) The temperature in the center of the sun spot is too high, which leads to fatigue damage to the metal material where the sun spot is directly irradiated; (2) ) The heat exchange efficiency of the heat exchanger is low, and the light-to-heat conversion efficiency is high
