Abstract

The invention discloses a denitration smoke flue guide plate for a thermal power plant. The denitration smoke flue guide plate for the thermal power plant comprises a smoke inlet pipe, a smoke straight-through pipe and a guide plate body a. A connecting opening is formed in the top circumferential end surface of the smoke inlet pipe through a leakproof rubber sleeve. An arc-shaped smoke conveyingpipe is installed at the bottom of the smoke inlet pipe. An inclined pipe is installed on the right side of the arc-shaped smoke conveying pipe through a connecting rubber sleeve. The smoke straight-through pipe is installed at one end of the inclined pipe, and a smoke conveying opening is formed in the bottom of the smoke straight-through pipe. The guide plate body a is installed in a groove formed in the inclined pipe, the smoke straight-through pipe is composed of a combined pipe a and a combined pipe b, the guide plate body a penetrates through the inclined pipe and the smoke straight-through pipe and is provided with the guide plate body b through a connecting arc-shaped opening, and storage square grooves are formed in the guide plate body a. According to the denitration smoke flue guide plate for the thermal power plant, the smoke is effectively and evenly distributed in the smoke conveying process, so that the burden of a denitration system of a unit and the environmental protection risk are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of denitrification, and in particular relates to a deflector for a denitrification flue in a thermal power plant. Background technique [0002] Nowadays, thermal power plants will produce a large amount of polluting gases during production and operation, which are generally serious. Desulfurization, denitrification and dust removal projects are required to meet the national emission standards and avoid greater pollution. [0003] After adding a denitrification system to the furnace boiler, the flow field of the denitrification flue is uneven, resulting in uneven denitrification ammonia injection, which increases the operating burden and environmental protection risks of the denitrification system of the power unit. Contents of the invention [0004] The purpose of the present invention is to provide a deflector for the denitrification flue of a thermal power plant, so as to solve the uneven flow field of t...
