Catalytic flue gas desulfurization device

Abstract

The invention discloses a catalytic flue gas desulfurization device which comprises a desulfurization reactor, the interior of the desulfurization reactor is divided into a flue gas distribution layer, a catalyst placement layer and a flue gas overflow layer from bottom to top, a gas distribution supporting structure is arranged in the flue gas distribution layer, a catalyst is placed in the catalyst placement layer above the gas distribution supporting structure, and the flue gas overflow layer is arranged in the flue gas distribution layer. A catalyst partition plate is arranged above the gas distribution supporting structure in the desulfurization reactor and comprises a main plate and wing plates, wherein the main plate is arranged along the first vertical surface and is used for separating the catalyst placement layer, and the wing plates are arranged along the second vertical surface, are connected to two sides of the main plate and are distributed at intervals along the length direction of the main plate. The main plate can be effectively prevented from toppling due to extrusion of the catalyst, and the impact force on the catalyst partition plate in the vertical direction due to rapid flow when the catalyst is poured into the catalyst placing layer is relieved.

Description

[0001] This application is related to an earlier Chinese application with application number 202120944544.9 (hereinafter referred to as the earlier application) filed by the same applicant, and the contents of the earlier application may be incorporated into this application in part or in whole. technical field [0002] The embodiments of the present application relate to the technical field of flue gas desulfurization, and in particular, to a catalytic flue gas desulfurization tower, a catalytic flue gas desulfurization device, and a maintenance method for a catalytic flue gas desulfurization tower. Background technique [0003] Catalytic flue gas desulfurization technology is a known desulfurization technology with promising application. sulfuric acid. When the sulfuric acid adhering to the catalyst reaches a certain level, the catalyst can be washed with a regeneration solution (usually using dilute sulfuric acid and / or water) to remove the adhering sulfuric acid on the c...
