The invention relates to an air distributor system used in the gas-solid heat exchange process and a gas-solid heat exchange method, and belongs to the field of industry waste heat utilization. The problems that an existing air distribution system is uneven in air distribution, heat exchange between wind and high-temperature materials is uneven, the heat recycling efficiency is low, and the temperature generated after heat exchange is low are solved. The air distributor system comprises hoods, a circulation hot air pipe, an air duct and a gas-solid heat exchange device. High-temperature solidmaterials enter the gas-solid heat exchange device, circulation hot air and air are led into a circulation hot air inlet and an air inlet correspondingly, the hoods are evenly arranged at the lower portion of the gas-solid heat exchange device, the two-layer air outlet design is adopted in the hoods, the high-temperature solid materials sequentially exchange heat with upper-layer circulation hot air and lower-layer air, and stepped cooling is finished. By means of the air distributor system used in the gas-solid heat exchange process and the gas-solid heat exchange method, gas-solid uniform heat exchange can be achieved, stepped heat exchange recycling of high-temperature solid sensible heat through two paths of gas can be achieved, heat exchanging can be uniform, high-quality hot air canbe obtained, and the waste heat utilization efficiency can be better improved.
