Embodiment 1

[0037] like Figure 1-Figure 6As shown, the fluidized bed semi-drying desulfurization system includes a pre-dusting device connected with a desulfurization tower and a bag filter; the pre-dusting device includes a hollow shell 2, and both sides of the inner surface of the hollow shell 2 are The guide rails 3 are provided, and the number of the guide rails 3 is a pair. The other pair of the guide rails 3 are distributed in a mirror image with the vertical center line of the hollow shell 2 acting as a mirror image line. The upper end and the lower end are fixedly connected to the guide column 4 by welding, the upper sleeve of the guide column 4 is provided with a circular column-shaped guide plate 5, and the other pair of the guide plates 5 are fixedly connected to the disc-shaped disc-shaped body. 6. An insertion port 22, a cylindrical opening 7 and a rectangular parallelepiped opening 8 are sequentially opened on the upper end of the disc-shaped body 6 from one side to the oth...

Abstract

A fluidized bed semi-dry desulfurization system and method, comprising a pre-dust removal device connected to a desulfurization tower and a bag filter; the pre-dust removal device comprises a hollow shell, and both sides of the inner surface of the hollow shell are provided with Guide rails, the number of the guide rails is a pair, and the other pair of the guide rails are mirrored by the vertical center line of the hollow shell as a mirror image line, and the upper end and the lower end of the inner surface of the guide rail are fixedly connected A guide column is attached to the guide column, a guide plate is sleeved on the guide column, and a disc-shaped body is fixedly connected between the other pair of the guide plates. Combined with other structures or methods, the defects of the prior art that the adsorption tank body is not conducive to replacement in the pre-dust removal device, the pre-dust removal performance of the pre-dust removal device after a long period of use is not good, and the dedusting effect of the pre-dust removal device are effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of fluidized bed and also to the technical field of semi-dry desulfurization, in particular to a fluidized bed semi-dry desulfurization system and method. Background technique [0002] The circulating fluidized bed flue gas desulfurization process is a new semi-dry technology developed by the German Lutsch company in the late 1980s. This process is based on the principle of circulating fluidized bed. Through the multiple recirculation of the absorbent, the contact time between the absorbent and the flue gas is prolonged, and the utilization rate of the absorbent and the desulfurization efficiency are greatly improved. The CFB FGD process is similar to the CFB boiler, which makes the bed reach a state of intense turbulence, thereby enhancing the absorption of sulfur dioxide by the absorbent. [0003] Furthermore, CFB semi-dry desulfurization is a desulfurization technology used for desulfurization of...
