Abstract

Fluidized bed semi-drying desulfurization system and method. The system includes a pre-dust removal apparatus connected to a desulfurization column and a bag-type dust remover, wherein the pre-dust removal apparatus includes a hollow shell, wherein a pair of guide rails are arranged on the two sides of the inner surface of the hollow shell, and the other pair of guide rails are distributed in a mirror arrangement with the vertical central line of the hollow shell being a mirror line. Guide columns are fixedly arranged between the upper end and the lower end of the inner surface of each guide rail. A guide plate sleeves each guide column. A disc body is fixedly connected between the other pair of the guide plates. By means of other structures or methods, the system can avoid the defects that an adsorption tank body is difficult to replace in a pre-dust removal apparatus in the prior art, which causes poor dust removal performance of the pre-dust removal apparatus after a certain operation period and adverse effect on dust removal effect of the pre-dust removal apparatus.

Description

technical field [0001] The 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 Lurgi Company in Germany in the late 1980s. This process is based on the principle of circulating fluidized bed, through repeated recirculation of the absorbent, prolonging the contact time between the absorbent and the flue gas, greatly improving the utilization rate of the absorbent and the desulfurization efficiency. The circulating fluidized bed flue gas desulfurization process is similar to the circulating fluidized bed boiler, which makes the bed reach a state of intense turbulence, thereby enhancing the absorption of sulfur dioxide by the absorbent. [0003] Furthermore, circulating fluidized bed semi-dry desulfuri...
