Flue-type denitrification reactor

Abstract

The invention provides a flue-type denitrification reactor. A truss in the reactor is eliminated, and the load of the whole reactor borne by the truss originally is incorporated into the bearing parameter of a reactor wall panel to be designed; by increasing the thickness of the reaction wall panel, a horizontal profile steel reinforcing rib and a vertical profile steel reinforcing rib are arranged near a rectifier device layer and a catalyst supporting beam, and a horizontal angle steel reinforcing rib and a vertical angle steel reinforcing rib are arranged between the profile steel reinforcing ribs to ensure that the reactor meets the original bearing requirements, so that the layer height of the reactor is reduced, and the situation that a reactor shell does not deform is ensured. Reinforcing ribs of beams and posts are arranged at the outer side of the shell of the reactor and are covered with a heat insulation material, thereby the problems of dust accumulation and unsmooth flow field caused by the reinforcing ribs in the reactor are solved.

Description

technical field [0001] The invention relates to a denitrification reactor, in particular to a flue-type denitrification reactor, which is suitable for the reactor of SCR denitrification technology in coal-fired power stations. Background technique [0002] For the SCR (Selective Catalytic Reduction) denitrification project construction of coal-fired power plants, the reactor is the core component of the SCR device, which provides NOX and NH in the flue gas. 3 Generate N on the catalyst surface 2 and H 2 The O place, its main function is to carry the catalyst, provide space for the denitrification reaction, and at the same time ensure the smooth flow of the flue gas and the uniform distribution of the airflow, creating conditions for the smooth progress of the denitrification reaction. [0003] There are mainly two types of catalytic reactors in industrial waste gas treatment projects: fixed bed and fluidized bed. At present, fixed bed reactor is widely used, and denitrific...

Problems solved by technology

[0008] In addition, in the above three force models, most of the reactor insulation materials are external (that is, the insulation material is on the outside of the reactor shell wall) so that the internal components of the reactor can be stressed as much as possible under high temperature conditions. When beams, When the column reinforcement ribs and other components are arranged on the inner side of the wall plate, it is easy to cause dust accumulation and uneven flow field
