Embodiment 1

[0029] Such as Figure 1-6 As shown, the catalyst arrangement structure assembly with adjustable angle in the flue described in this embodiment includes support beams 2 fixed on both sides of the flue 1 and several catalyst modules 3 installed on the support beams. The catalyst modules are connected end to end. Arranged in a folding fan shape and installed on the support beam. The catalyst module includes a catalyst frame 31 and several catalyst units 32 installed in the catalyst frame.

[0030] Several layers of supporting beams are installed along the height direction of the flue, and each layer of supporting beams is divided into fixed beams 21 and movable beams 22 . One end of the catalyst is installed on the fixed beam, and the other end is installed on the movable beam.

[0031] A number of positioning columns I 211 are evenly distributed on the upper surface of the fixed beam, and the bottom of the catalyst frame has positioning holes 311, and the size of the position...

Embodiment 2

[0038] Such as Figure 7-9 As shown, the difference between this embodiment and Embodiment 1 is that the catalyst modules are parallel to each other and installed on the support beam at a certain angle. The two catalyst modules are connected by a partition 4, and the flue gas passes through the catalyst modules. The gaps between the modules are blocked by partitions to ensure that the flue gas passes through the catalyst modules.

Abstract

The invention relates to the field of denitration catalyst equipment. Specifically, the invention relates to an angle-adjustable catalyst arrangement structure assembly in a flue. The assembly comprises supporting beams fixed on two sides of a flue and a plurality of catalyst modules mounted on the supporting beams. A catalyst module comprises a catalyst frame and a plurality of catalyst units installed in the catalyst frame; a plurality of layers of supporting beams are installed in the height direction of the flue; and each layer of supporting beam is divided into a fixed cross beam and a movable cross beam. The catalyst modules are mounted on the supporting beams, so that the mounting process is convenient; when the catalyst module is damaged and needs to be replaced, the catalyst module can be conveniently and independently disassembled and replaced; the catalyst modules are arranged in the flue at a certain angle, so that the pressure drop can be reduced, and the mounting angles of the catalyst modules can be adjusted within a certain angle range by adjusting the positions of toothed plates on the movable cross beam, so as to adapt to flues with different flow field conditions, so that the catalytic efficiency is higher, and the denitration catalytic effect is better.

Description

technical field [0001] The invention relates to the field of denitration catalyst equipment, in particular to a catalyst arrangement structural component with an adjustable angle in a flue. Background technique [0002] At present, the arrangement of denitration catalysts in the flue is relatively simple, and the denitrification catalyst modules are directly arranged in the flue perpendicular to the direction of the flue. This arrangement is likely to cause a large pressure drop in the flue. Emission, after some catalysts are damaged, it is extremely inconvenient to replace them, and some catalysts are installed in the flue at a certain angle. Although the pressure drop is reduced to a certain extent, once the angle of the existing catalyst in the flue is determined, it cannot be changed. Angle, can not adapt to a variety of flue environments with different flow fields. Contents of the invention [0003] The main purpose of the present invention is to provide a catalyst a...
