Solar particle reactor with V-shaped groove

Abstract

The invention discloses a solar particle reactor with a V-shaped groove, comprising a backflow base, a reaction cavity, a quartz window, a working medium inlet, and a working medium outlet. One end of the reaction cavity is connected with the backflow base, and the other end of the reaction cavity is provided with the quartz window for incident solar radiation; the side surface of the reaction cavity is provided with a circle of V-shaped groove; the radial section of the V-shaped groove is in a V shape; the depth of the V-shaped groove is smaller than the radius of the reaction cavity; the working medium inlet is formed in the side face of the backflow base; and the working medium outlet is formed in the side face of the reaction cavity and located between the V-shaped groove and the quartz window. Continuous work can be achieved, the circulation time of particles in the reactor can be reasonably distributed, the calcium carbonate reaction proportion is increased, and efficient conversion and storage of solar energy are achieved; and meanwhile, deposition of the particles on the surface of the quartz glass can be reduced, high solar energy capturing efficiency is achieved, it can be guaranteed that the cleanliness of the quartz glass is improved, and use and maintenance are facilitated, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a solar reactor, in particular to a solar particle reactor with a V-shaped groove. Background technique [0002] In today's society, traditional fossil fuels are still an important source of energy to promote social development and maintain the needs of residents' lives, but the reserves of fossil fuels are limited, which is not enough to support the long-term development of human beings, and the use of carbon-containing organic fuels has brought many serious environmental problems. Therefore, turning to the development and utilization of new energy has become particularly critical. Among the many types of renewable energy, solar energy is currently known to be the most widely distributed and abundantly stored clean energy that can achieve long-term development and utilization. However, for solar energy Development faces a series of problems. For example, the sun’s radiation will fluctuate due to factors such as location, seaso...

Problems solved by technology

[0004] When the particles circulate in the reactor, they tend to stay on the inner surface of the quartz glass. When the surface temperature of the particles rises, it is easy to cause the quartz glass to break due to uneven temperature. Usually, the protective gas nozzles are arranged in a special way to inject the protective gas. , to remove the particle powder on the quartz glass, but the incident solar energy will be taken away due to the intervention of too much protective gas, and the energy conversion and storage efficiency will be reduced; in addition, when the particles flow inside the reactor, it is necessary to ensure that the particles and the solar radiation energy With sufficient contact time, the residence time of particles in the reactor becomes the most important factor in improving the energy storage efficiency of granular media
