A solar particle reactor with v-grooves

Abstract

The invention discloses a solar particle reactor with a V-shaped groove, which comprises a reflux base, a reaction chamber, a quartz window, a working medium inlet and a working medium outlet, one end of the reaction chamber is connected to the reflux base, and the other end of the reaction chamber is arranged A quartz window for incident solar radiation, a V-shaped groove is arranged on the side of the reaction chamber, the radial section of the V-shaped groove is V-shaped, the depth of the V-shaped groove is smaller than the radius of the reaction chamber, and the working fluid inlet It is arranged on the side of the reflow base, and the working medium outlet is arranged on the side of the reaction chamber, and is located between the V-shaped groove and the quartz window. The present invention can realize continuous work, can reasonably distribute the cycle time of particles inside the reactor, increase the proportion of calcium carbonate reaction, and realize high-efficiency conversion and storage of solar energy; at the same time, the present invention can reduce the deposition of particles on the surface of quartz glass, Achieving high-efficiency solar energy capture efficiency can also ensure that the cleanliness of quartz glass is improved, which is beneficial to use and maintenance and reduces maintenance costs.

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
