Example Embodiment

[0030] Example one

[0031] The laminated rectifier for SCR denitration equipment of the present invention includes an upper rectifier plate 1 and a lower rectifier plate 2 stacked together. The upper rectifier plate 1 is provided with a plurality of regularly arranged rectifier holes I that penetrate the upper rectifier plate body. 3. The lower rectifying plate 2 is provided with a rectifying hole II 4 corresponding to the rectifying hole I 3, which penetrates the plate body of the lower rectifying plate. The rectifying hole I 3 and the rectifying hole II 4 are partially overlapped in the vertical direction. A rectifying channel that vertically penetrates the body of the rectifier. In this embodiment, the upper rectifying plate 1 and the lower rectifying plate 2 have the same area and the same size, and both are rectangular plates;

[0032] Such as figure 2 As shown, the rectifying hole I 3 includes a plurality of square holes I 31 of uniform size and evenly distributed horizonta...

Example Embodiment

[0036] Example two

[0037] In this embodiment, the upper rectifying plate 1 and the lower rectifying plate 2 are still rectangles with the same area and four overlapping sides when stacked, and they are all arranged vertically and horizontally and integrally welded by steel bars with a thickness of less than 1 cm. Figure 5 As shown, the upper rectifying plate 1 adopts a sieve structure, and the whole of the upper rectifying plate 1 is evenly divided into a plurality of rectifying holes I3 by steel bars. As can be seen from the figure, the rectifying holes I 3 are rectangular holes, and the rectifying holes I 3 have two specifications. The width of the rectifying holes I 3 arranged at both ends of the lower rectifying plate 2 is smaller than that of the rectifying holes I 3 arranged in the middle of the lower rectifying plate 2. In this embodiment, the width of the rectifying holes I 3 at both ends is approximately equal to that of the rectifying holes I 3 in the middle. Half of ...

Example Embodiment

[0038] Example three

[0039] Such as Figure 8 As shown (the small solid box in the figure represents the rectification hole I, the small dotted box represents the rectification hole II, and the shaded part represents the rectification channel), the difference between the second embodiment and the first implementation is that the rectification hole I 3 and the rectifier The holes II 4 are arranged obliquely, in which, along the same direction of the horizontal plane, the rectifying hole I 3 is set at a 45° left-inclined, the rectifying hole II 4 is set at a right-inclined 45°, and any two rectifying holes I 3 on the upper rectifying plate The two rectifying holes II 4 corresponding to the lower rectifying plate overlap at both ends in the vertical direction, correspondingly forming four diamond-shaped rectifying channels.

Abstract

The invention discloses a cascading type rectifier used for SCR denitration device, comprising an upper rectifying plate and a lower rectifying plate that are laminated together; wherein the upper rectifying plate is provided with a plurality of regular spread rectifying holes I penetrating the upper rectifying plate body, the lower rectifying plate is provided with rectifying holes II which correspond to the rectifying holes I and penetrates the lower rectifying plate body, the rectifying holes I and the rectifying holes II are partially laminated in vertical direction, and the laminated partforms a plurality of rectifying channels vertically penetrating the rectifier body. The rectifier is formed by adopting the upper and lower rectifying plates, and a plurality of rectifying channels are formed through overlap of the rectifying holes opened on the upper and lower rectifying plates in different directions, thus not only the effect of uniform smoke movement is achieved but also manufacturing cost can be saved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a laminated rectifier used for SCR denitrification equipment. Background technique [0002] my country is a country that uses coal as the main energy source, and coal-fired power generation is one of the most important ways of coal utilization in my country. According to my country's national conditions, coal-fired power generation will dominate in the 21st century. Among the many air pollutants emitted by coal-fired thermal power units, SO 2 And the dust is more harmful to the environment and is the main pollutant to be controlled. With the progress of society and the development of economy, the pollution of thermal power plants to the atmospheric environment has been widely concerned by people. Therefore, it is a severe challenge for the sustainable development of my country's energy field to effectively reduce pollutant emissions and improve the impact on the e...
