Dual-cavity type solar driven carbonaceous material reaction method and apparatus

Abstract

The invention discloses a dual-cavity type solar driven carbonaceous material reaction method and apparatus. A focused solar beam irradiates inside a light absorption cavity of a dual-cavity type heat absorption cavity after passing through a glass cover plate; solid particles enter into a separation disk surface of the light absorption cavity through a solid particle inlet; the solid particles and the separation disk surface can be used for absorbing solar light simultaneously, and the solar light is converted into heat energy; high-temperature hot solid particles enter into a downcomer inlet in the center of the light absorption cavity, and a downcomer outlet is connected to a reaction cavity by virtue of a pneumatic box; a preprocessed carbonaceous material is directly conveyed into the reaction cavity by virtue of a spiral conveying pipe and is mixed with hot ceramic particles from the pneumatic box, and the heat energy of the hot ceramic particles is absorbed by the carbonaceous material; meanwhile, the radiation energy of the separation disk surface of the light absorption cavity is absorbed to generate pyrolysis gas; reaction gas enters into a reaction gas product catalysis processing system from the gas outlet of the reaction cavity. The method disclosed by the invention can be used for improving the transfer rate of heat energy; meanwhile, the method can be used for solving the problems of uneven and changeable focus spots, and the service life of the light absorption cavity is prolonged.

Description

Technical field [0001] The present invention involves the field of solar heat chemistry, especially a method and device of a two -cavity solar -driving carbon -containing material reaction. Background technique [0002] Global solar radiation total amount is about 1.7 × 10 17 W, of which about 1%(1.8 × 10 15 W, equivalent to 1.9 trillion tons of standard coal / year), is 680 times the current annual energy consumption in my country, and solar energy contains huge development potential.However, solar energy flow density is relatively low, energy fluctuations are relatively large, and the storage costs are high. If photovoltaic grid -connected power generation is used, the impact on the power grid is relatively large. These problems have always affected the further development and utilization of solar energy.The solar thermal chemical method is to focus on the sunlight through the consecutive light, increase energy flow density, reduce energy output fluctuations through heat storage ...
