Example Embodiment

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-3 As shown in the figure, the folding fan catalyst module of the present invention includes a box body 1 and a catalyst assembly 3 arranged in a folding fan type inside the box body. 31; A plurality of catalyst units are arranged to form a catalyst assembly.

[0023] The box body penetrates front and rear, and includes a top plate 11, a side plate 12 and a bottom plate 13. A vertical plate 2 is installed between the top plate and the bottom plate of the box body for connecting and fixing the catalyst assembly.

[0024] The vertical plate is a thin plate with folded corners, and the angle of the folded corner and the angle between the catalyst units are complementary angles to each other. The flue gas leaks from the gap between the catalyst components or the gap between the catalyst component and the side plate, the limit rod 4 can be detachably ...

Abstract

The invention relates to the field of flue gas denitration catalyst equipment, and in particular relates to a folding fan type catalyst module, the folding fan type catalyst module comprises a box body and catalyst components which are arranged in a folding fan type in the box body, wherein the catalyst components comprise a plurality of catalyst units, the box body penetrates back and forth and comprises a top plate, a side plate and a bottom plate; a vertical plate is arranged between the top plate and the bottom plate of the box body and is used for connecting and fixing the catalyst components; the folding fan type catalyst module solves the problems of small catalyst arrangement volume, small contact area between flue gas and a catalyst, large pressure loss, relatively high resistanceand insufficient denitration performance of the catalyst in a denitration reactor in the prior art, greatly increases the contact area between the flue gas and the surface of the catalyst units, reduces the pressure loss of the flue gas passing through the catalyst, and improves the catalytic effect.

Description

technical field [0001] The invention relates to the field of flue gas denitrification catalyst equipment, in particular to a folding fan catalyst module. Background technique [0002] With the continuous strengthening of my country's environmental protection policies, SCR denitrification technology has been maturely promoted and applied in the thermal power industry. Industries such as steel, coking and distributed energy are undergoing ultra-low emission transformation, but SCR denitrification technology is not too mature in non-electric industries such as steel. Experience is used as a reference, and further research and optimization are needed. As the core component of SCR technology, the SCR denitrification catalyst module directly determines the overall performance of the SCR denitrification system. [0003] Under the situation that coal-fired power plants generally implement ultra-low emission of nitrogen oxides, stricter emission limits for nitrogen oxides are propose...
