Description

technical field

[0001] The invention relates to a large-scale fluidized bed reactor suitable for wide screening of fluidized particles, especially suitable for a gas-solid reaction system in which solid particles are used as reaction raw materials, and belongs to the technical field of chemical equipment. Background technique

[0002] In the chemical process, in order to achieve the purpose of effective heat and mass transfer, many productions are usually carried out in fluidized bed reactors. It also involves many solid raw materials with wide particle size distribution or solid particles as reaction raw materials, such as pulverized coal gasification, ore burning in metallurgical industry, etc. For this type of system, due to the wide distribution of solid particle size or the gradual change of particle size during the reaction process, the reactor is required to have high operating flexibility, which can ensure that the particle size of solid particles changes within a ce...
