Solar high-temperature reactor integrating phase-change storage energy and chemical storage energy

Abstract

The invention discloses a solar high-temperature reactor integrating phase-change storage energy and chemical storage energy and belongs to the field of solar high-temperature heat utilization. A quartz glass board is connected to the open end of the left side of a reactor shell, a reaction cavity is constituted by the quartz glass board and the reactor shell, a working medium inlet is formed in the left side of the reactor shell, a working medium outlet is formed in the right side of the reactor shell, an overall porous catalyst is arranged in the reactor shell, a phase-change energy storageis mounted on the outer side face of the reactor shell, a phase-change energy storage shell is arranged on the outer surface of the phase-change energy storage, and the phase-change energy storage shell is wrapped with a heat preservation layer. The solar high-temperature reactor can still provide heat energy required by a reaction when illumination is unstable and the solar high-temperature reactor is in a shadow place, and continuous conducting of the chemical reaction is kept; in addition, the temperature of the edge of a porous structure of a chemical reaction layer can be maintained, theradial temperature gradient is decreased while a reaction area is enlarged, and structural collapse caused by stress concentration is prevented; and part of heat in waste gas is recovered to preheat inlet gas.

Description

technical field [0001] The invention belongs to the field of high-temperature heat utilization of solar energy, in particular to a high-temperature solar reactor integrating phase change energy storage and chemical energy storage. Background technique [0002] The situation of energy shortage, air pollution, and climate change is becoming more and more serious. It is an inevitable trend to accelerate the development of new energy and the clean utilization of fossil energy, and to transform to clean, low-carbon, and green development. As a typical clean and sustainable energy source, solar energy has received worldwide attention and extensive research. Solar energy has the disadvantages of intermittent, low density and instability, and it is difficult to supply continuously. At present, three methods of sensible heat energy storage, latent heat energy storage and thermochemical energy storage are often used to realize solar energy storage.
