Problems solved by technology

[0006] Although the existing porous plate type and blunt body internal components can enhance particle back-mixing, increase particle concentration, and improve reaction efficiency, the system resistance also increases
Moreover, the existing internal components have no significant effect on the redistribution and redirection of the airflow, which increases the degree of wear of the internal components
The structure of the traditional flow-guiding internal components is complicated, which increases the manufacturing cost

Abstract

The invention relates to a compound internal member applied to a circulating fluidized bed desulfuration reactor. The compound internal member comprises at least one internal member unit, wherein the internal member unit comprises an opening type funnel and an air distribution plate, a plurality of bar-shaped holes are formed in the side wall of the opening type funnel and are alternatively arranged in an upper row and a lower row, the air distribution plate is provided with at least two rows of fan-shaped holes along the radial direction, two adjacent rows of fan-shaped holes are arranged in a staggered manner, and the opening type funnel and the air distribution plate are connected through a support column. The compound internal member is capable of improving axial and radial distribution of a granular speed, increasing the granule backmixing and improving the fluidization quality of a fluidized bed, thereby increasing the utilization rate of a desulfurizing agent and the desulfuration reaction efficiency.

Description

technical field [0001] The invention relates to an internal component in a circulating fluidized bed desulfurization reactor, in particular to a composite internal component installed on the top of the circulating fluidized bed desulfurization reactor to increase internal circulation, increase the residence time of desulfurizing agent, and improve reaction efficiency. It is used in industrial flue gas treatment and other fields. [0002] The present invention also relates to a circulating fluidized bed desulfurization reactor equipped with the above internal components. Background technique [0003] The traditional circulating fluidized bed desulfurization reactor is designed as an empty tower, and the circulation of desulfurizing agent mainly relies on an external separator. Therefore, the application of circulating fluidized bed desulfurization technology to engineering projects will affect the original production section. The second-generation internal circulation circul...
