Abstract

The invention discloses a multi-stage injection-type line focus solar absorption reactor for middle and low temperature solar thermochemistry. The reactor includes a line focus reflective mirror array, variable diameter absorption reaction tubes and an injection pipe. The variable diameter absorption reaction tubes are arranged in a plurality of mirrors among the reflective mirror array; part of the reactant enters the absorption reaction tubes from the inlets on the ends of the reaction tubes, and the remaining reactant is injected into the absorption reaction tubes in a multi-stage way through the injection pipe along the tube; after entrance into the reaction tubes, the reactant is heated by the solar focused by the line focus reflective mirror array, and generates endothermic reaction under the catalyst condition, so as to convert solar energy into chemical energy of the resultant and improve response reactant grade. The invention improves the chemical processes and apparatus, so that the structure reasonably matches the parameters such as specific reaction characteristics and working fluid status in the absorption reaction tubes. The reactor achieves the efficient energy transfer and transformation, improves the overall reaction efficiency and reduces the overall energy consumption.
