Problems solved by technology

[0007] The gasification process of fossil fuels such as coal and biomass mainly includes pyrolysis and residual carbon gasification. The existing conventional gasification methods usually integrate these two main reactions. If solar energy is used to drive solid fuel gas This technical method is still used in the chemical process, which not only reduces the effective utilization rate of solar energy, but also increases the irreversible loss in the heat collection process, and at the same time, the tar content in the generated syngas will also be high

Abstract

The invention discloses a solar high-temperature thermochemical gasification reactor. The reactor mainly comprises a black body cavity, a reaction chamber, a flow guiding column, a gas guide pipe, a solid guide pipe, servomotors and the like. By using the reactor, solar energy can be more efficiently used for driving solid hydrocarbon fuels such as coal, biomass and the like to be subjected to gasifying reaction and independently completing processes such as preheating, pyrolyzing, gasifying and the like contained by the gasifying reaction, so that the conversion of the solar energy to high-quality synthetic gas can be realized, and the current problems of high solar energy storage difficulty, poor renewable energy source conveying stability and the like are solved.

Description

technical field [0001] The invention relates to the technical field of high-temperature solar thermochemical utilization, in particular to a solar high-temperature thermochemical gasification reactor. Background technique [0002] In order to cope with the rapid economic development and social progress, the demand for energy is increasing year by year, and the problems of energy shortage and environmental pollution caused by the large-scale burning of fossil energy are becoming more and more prominent. For this reason, renewable clean energy such as solar energy and biomass will play an increasingly important role in the future. [0003] As a clean and renewable energy, solar energy is projected to the earth's surface in the form of radiation. It is the most abundant energy available to human beings. It has some advantages that ordinary energy cannot match, such as cleanliness and huge resources. At present, the utilization technology of solar energy mainly includes solar p...
