Problems solved by technology
However, when the solid powder is transported into the reactor by the traditional method, it is likely to bring in air, which is easy to cause danger. Therefore, it is necessary to build a special powder delivery system to avoid bringing air into the reactor, but in this way It will make the whole system more complicated and increase the cost

The invention discloses a gas-solid double-phase reaction device and a gas-solid double-phase reaction technology. The gas-solid double-phase reaction device comprises 1, a reactor, 2, a combustion device, wherein the combustion device is located in the reactor; combustible matters and combustion-supporting gas burn through the combustion device so that a certain temperature of the reactor is maintained; and solids of the combustible matters enter into the reactor with the combustion-supporting gas, and 3, a gas-solid separator, wherein the gas-solid separator is utilized for generation of tail gas produced in the reactor. Through the gas-solid double-phase reaction device and the gas-solid double-phase reaction technology, reaction efficiency is improved without an additional heat source and solid material caking is delayed.
Description
technical field [0001] The present invention relates to the field of gas-solid two-phase reaction, specifically, the present invention relates to the gas-solid two-phase reaction that can be used in gas-solid oxidation reaction, gas-solid reduction reaction and the occasion (for example, the synthesis of material etc.) that is not redox reaction Device and gas-solid two-phase reaction process. Background technique [0002] Generally, for the gas-solid two-phase reaction, the gas-solid two-phase contact is relatively sufficient in the fluidized bed reactor, therefore, it can be considered that the fluidized bed is one of the preferred equipment for the gas-solid two-phase reaction. Compared with fixed bed reactors, fluidized bed reactors have many advantages, but there are also some disadvantages. For example, in general, the temperature required for the reaction is maintained in the reactor by passing hot gas into the fluidized bed reactor. Therefore, the fluidized bed reac...
