Catalytic flue gas desulfurization tower

Abstract

The invention discloses a catalytic flue gas desulfurization tower, which performs flue gas desulfurization through desulfurization reactors, and comprises a left desulfurization reactor vertical column, a right desulfurization reactor vertical column, a left desulfurization reactor vertical column and a right desulfurization reactor vertical column, the right side desulfurization reactor vertical column comprises at least two desulfurization reactors; an air inlet pipe network, an exhaust pipe network and a regeneration liquid circulation system; the outline of the desulfurization reactor forms a first rectangular body, and the vertical overall outline of the left desulfurization reactor and the vertical overall outline of the right desulfurization reactor respectively form a second rectangular body; and the overall outline of the desulfurization tower main body consisting of the left side desulfurization reactor vertical column, the right side desulfurization reactor vertical column and the frame type supporting structure forms a third rectangular body. The whole desulfurization tower main body is more attractive, and meanwhile, the space occupied by the whole catalytic flue gas desulfurization tower is more sufficiently distributed to the desulfurization reactor, so that the waste of the peripheral space of the desulfurization reactor is reduced.

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...
