1. A method for preparing hydrogen-rich gas from solid organics, the method comprising:
heating solid organic raw materials in a pyrolysis reaction device for pyrolytic formation of a gaseous product and steam; and
performing gasification of the gaseous product and steam in a moving bed gasification reaction device to generate hydrogen-rich gas, in which the gaseous product is generated from pyrolysis;
wherein the pyrolysis reaction device is in parallel with the moving bed gasification reaction device, wherein, by passing through a solid heat carrier grading-dedusting device, the solid heat carrier is divided into two parts that are fed into the pyrolysis reaction device and moving bed gasification reaction device, respectively, wherein, when leaving the pyrolysis reaction device and moving bed gasification reaction device, the two parts of solid heat carrier are fed into a riser and combustion reactor to be heated and raised, and are then passed into the solid heat carrier grading-dedusting device to be further divided into two parts, wherein the two further-divided parts are then fed into the pyrolysis reaction device and the moving bed gasification reaction device, respectively, again to create a cycle;
wherein the part of the solid heat carrier that is fed into the pyrolysis reaction device is used as a heating medium for the pyrolysis, and the other part of the solid heat carrier that is fed into the moving bed gasification reaction device is used as a heating medium for the gasification.
