Continuous solar thermochemical solid particle reactor capable of regenerating heat

Abstract

The invention discloses a continuous solar thermochemical solid particle reactor capable of regenerating heat. According to the technical scheme, the device mainly comprises a reduction part, an oxidation part, a material storage part and a material conveying part. According to the invention, metal oxide small particles are heated by using high temperature generated by a solar concentrating and heat collecting technology, so that a clean fuel is prepared, fossil energy does not need to be consumed, and the environmental pollution is almost zero. The mode that the reduction cavity and the oxidation cavity are separated is adopted, and the continuity of solar thermochemical fuel preparation is effectively achieved. The vertical design avoids the pollution of small metal oxide particles to the glass surface, the retention time of the small metal oxide particles in the reactor can be prolonged by the way of filling the hindering particles, and meanwhile, the thermal shock of larger temperature difference to the reactor is avoided. Through heat exchange between the small metal oxide particles in the oxidation cavity and the small metal oxide particles around the screw rod, heat regeneration of the high-temperature metal oxide is realized, and the solar energy utilization efficiency of the solid particle type reactor is improved.
