Bubbling fluidized bed body structure capable of simultaneously realizing winnowing and drying

Abstract

The invention discloses a bubbling fluidized bed body structure capable of simultaneously realizing winnowing and drying. The bubbling fluidized bed body structure capable of simultaneously realizing winnowing and drying comprises a shell body and an air distribution plate, wherein the shell body and the air distribution plate enclose to form a fluidized bed holding chamber; the groove-shaped air distribution plate tilts from the feed end of a bed body to the discharge end of the bed body, the air distribution plate mainly consists of a bottom air distribution plate in the middle and side air distribution plates on the two sides, bottom ventilating holes and side ventilating holes which are communicated with sectional air chambers are respectively formed on the bottom air distribution plate and the side air distribution plates, and the bottom air distribution plate is formed by tandem connection of more than three sections of air distribution component plates; a front end air distribution component plate closest to the feed end of the bed body is tooth-shaped or the like, and air nozzles towards the discharge end are arranged at the bottom ventilating holes; air caps with hole mouths which are uniformly distributed are arranged on other air distribution component plates, and discharge outlets are formed in the tail parts of other air distribution component plates; side air nozzles towards a position right above the bottom air distribution plate are arranged at the side ventilating holes of the side air distribution plates. The bubbling fluidized bed body structure capable of simultaneously realizing winnowing and drying has the advantages that the structure is simple and the effects of drying wet particle materials to proper moisture and winnowing the materials for sorting and separation according to particle size can be simultaneously realized.

Description

[0001] technical field [0002] The invention relates to a bed body structure and components of a fluidized bed, in particular to a wind separation and drying bed structure of a fluidized fluidized bed. Background technique [0003] At present, there are quite a lot of equipment and patent documents related to winnowing and drying. Since the same equipment is required to have the function of moderate drying of wet granular materials and the function of particle size winnowing and grading separation, the existing technology can meet this application effect and technical requirements. Equipment is not yet available. [0004] Most of the existing air separation drying equipment can achieve the effect of moderate drying of water, but it is extremely rare to achieve the effect of particle size air separation and fractionation at the same time; even if individual equipment or devices can simultaneously achieve the effect of particle size air separation and fractionation, but this ...

Problems solved by technology

[0004] Most of the existing air separation drying equipment can achieve the effect of moderate drying of water, but it is extremely rare to achieve the effect of particle size air separation and fractionation at the same time; even if individual equipment or devices can simultaneously achieve the effect of particle size air separation and fractionation, but this The effect of such equipment to achieve moderate drying of moisture is not ideal, and the amount of dust separation is too large, especially after being used in the coking coal preparation process, it brings many problems such as coal quality segregation and coke oven gas purification.

It is also because those skilled in the art know very little about the mechanism of wet granular material particle size component and winnowing fractionation and separation, do not grasp it thoroughly, and do not study deeply, which causes the existing winnowing drying equipment not only to have poor structural design Reasonable, but not fully functional

[0005] Previously, there have been patent documents reporting the bed structure of full-boiling swirling fluidized bed, but the existing bed structure of full-boiling swirling fluidized bed can only be applied to the moderate drying of wet granular materials, and does not have particle size winnowing and fractionation at all. function, the application in industrial practice is subject to certain restrictions
