[0006] European patent EP1072855A1 discloses a multi-chamber segmented fluidized bed reactor. The parameters such as the length of the communication hole and the distance from the nozzle are clearly determined, and thicker material accumulation layers are formed inside and at both ends of the communication hole, effectively Inhibit the back-mixing between adjacent chambers, but this structure limits the conveying flux of granular materials (particle conveying speed <500mm / s). Larger, the space utilization rate of the fluidized bed reactor is greatly reduced

Abstract

The invention relates to a multi-chamber fluidized bed reactor, which can realize fast and high-throughput flow of the particle material from an upstream chamber to a downstream chamber, while avoiding particulate material backmixing and back flow between adjacent chambers. The multi-chamber fluidized bed reactor is composed of an air inlet (1), an air outlet (2), a feed port (3), a discharge port (4), a wind chamber (5), an air distributor plate (6), a fluidizing chamber (7) and n material flow controllers (8), wherein n is more than or equal to 1; and each material flow controller (8) comprises a partition (9), an orifice (10), a material down flow tube (11) and a bottom baffle (12). The partition divides the fluidized bed reactor is divided into n+1 secondary fluidizing chambers, the air inlet is connected to the air chamber, the air outlet is connected to the upper part of the fluidizing chamber, the feed port is connected to the first secondary fluidizing chamber, and the discharge port is connected to the No. n+1 fluidizing chamber.

Description

technical field [0001] The invention relates to a multi-chamber fluidized equipment, in particular to a multi-chamber fluidized bed reactor. Background technique [0002] The fluidized reactor has the characteristics of high heat transfer, mass transfer, and momentum transfer efficiency. It is a highly efficient multiphase reactor and has been widely used in the chemical industry such as heterogeneous catalysis and powder processing. Another main feature of the fluidized reactor is that the materials in the reaction chamber are in a fully mixed state, and some unreacted materials will be discharged along with the product. Therefore, a single-chamber fluidized bed reactor is not suitable for the production of high-purity products. [0003] In a multi-chamber fluidized bed, the granular materials in a single reaction chamber are in a fully mixed state, and the granular materials flow sequentially between adjacent reaction chambers. Generally speaking, the material level heigh...
