Specifically, please refer to Figures 5 to 7 , Figure 5 which is a three-dimensional structural schematic diagram of the tower body support of the vertical desulfurization tower provided in this embodiment connected to the wall panel and the cross beam;

[0039] Figure 6 which is a structural schematic diagram of the first support assembly in the grille fixing device provided in this embodiment connected to the wall panel; Figure 7 which is a structural schematic diagram of the second support assembly in the grille fixing device provided in this embodiment connected to the cross beam. From Figures 5 to 7It can be seen that the grid fixing device is used for a vertical desulfurization tower, and the vertical desulfurization tower includes a tower body support (not marked in the figure) and a plurality of wall plates 12 fixedly arranged around the tower body support. The vertical desulfurization tower further includes a plurality of groups of cross beams 11 arranged along the height direction of the vertical desulfurization tower. The cross beams 11 are fixedly arranged on the tower body support. The first end of the cross beams 11 in the same group is close to the first wall plate (not marked in the figure), and the second end of the cross beams 11 in the same group is close to the second wall plate (not marked in the figure). The first wall plate and the second wall plate are arranged opposite to each other. The grid fixing device includes a first support component (exemplarily, such as a first section steel 20) and a second support component (exemplarily, such as a second section steel 21) arranged in the same plane; the first support component is configured to be fixedly installed on the inner sides of the first wall plate and the second wall plate; the second support component is configured to be located between two adjacent groups of the cross beams 11 and is fixedly installed on two corresponding cross beams 11 arranged along the height direction; both the first support component and the second support component are used for clamping the grid device 30 (exemplarily, please refer to the following Figure 8 ). Thus, for the grid fixing device provided in this embodiment, the grid device 30 is clamped by the first support component and the second support component arranged in the same plane. The first support component is fixedly installed on the inner sides of two opposite wall plates 12 of the vertical desulfurization tower to clamp the grid device 30, and the second support component is arranged between two adjacent groups of the cross beams 11, and the second support component is fixedly installed on the inner sides of two corresponding cross beams 11 arranged along the height direction of the vertical desulfurization tower to clamp the grid device 30, which can improve the installation accuracy of the grid device 30, make the installation of the grid device 30 more convenient, and at the same time improve the supporting effect of the grid device 30 on the grid packing 13.

[0040] It should be noted that the present invention does not impose too many limitations on the fixed installation methods of the first support component and the second support component. Exemplarily, in some exemplary embodiments, the fixed installation methods of both the first support component and the second support component are welding fixation.

[0041] Preferably, the length direction of the first support assembly is parallel to the length direction of the wall panel 12; the length direction of the second support assembly is parallel to the length direction of the cross beam 11. Thus, the installation inclination degree of the grille device 30 can be reduced. It should be noted that the length direction of the wall panel 12 is the height direction of the vertical desulfurization tower. Exemplarily, in some exemplary embodiments, the vertical desulfurization tower is of a cuboid structure, and a plurality of groups of cross beams 11 are arranged along the height direction of the vertical desulfurization tower. Four cross beams 11 are arranged in each group, and the four cross beams 11 are all perpendicular to the first wall panel; the length direction of the first support assembly is parallel to the length direction of the first wall panel, and the length direction of the second support assembly is parallel to the length direction of the cross beam 11.

Thus, by using the two first profiled steels 20 as the first support assembly, the stability of the wall panel 12 can be improved, and the strength of the wall panel 12 can be effectively guaranteed; by forming the first clamping portion 201 between the two first profiled steels 20 to clamp the grille device 30, a good foundation is laid for improving the installation accuracy of the grille device 30. By forming the second clamping portion 211 between the two second profiled steels 21 to clamp the grille device 30, a further good foundation is laid for improving the installation accuracy of the grille device 30.

[0043] Furthermore, the distance between the two first profiled steels 20 is more than the width of the grille plate 10 in the grille device 30 by a first preset distance; the distance between the two second profiled steels 21 is more than the length of the grille plate 10 by a second preset distance. Thus, by making the distance between the two first profiled steels 20 more than the width of the grille plate 10 in the grille device 30 by the first preset distance, the grille device 30 can be more conveniently clamped and fixed to the wall panel 12; by making the distance between the two second profiled steels 21 more than the length of the grille plate 10 by the second preset distance, the grille device 30 can be more conveniently clamped and fixed to the cross beam 11.

[0044] It should be noted that, as can be understood by those skilled in the art, the present invention does not impose too many limitations on the values of the first preset distance and the second preset distance. Exemplarily, in some embodiments, the values of the first preset distance and the second preset distance are both not less than 10 mm and not more than 15 mm.

[0045] Preferably, the first steel section 20 includes a first channel steel, and one side where the concave surface of the first channel steel is located is fixedly connected to the wall panel 12; the second steel section 21 includes a second channel steel, and one side where the concave surface of the second channel steel is located is fixedly connected to the cross beam 11. Thus, by fixedly connecting one side where the concave surface of the first channel steel is located to the wall panel 12, the convex surface of the first channel steel is clamped with the grille device 30, which can improve the clamping stability between the grille device 30 and the first channel steel; by fixedly connecting one side where the concave surface of the second channel steel is located to the cross beam 11, the convex surface of the second channel steel is clamped with the grille device 30, which can improve the clamping stability between the grille device 30 and the second channel steel.

[0046] It should be noted that the present invention does not impose too many limitations on the types of the first steel section 20 and the second steel section 21, as long as the grille device 30 can be clamped with the first steel section 20 and the second steel section 21. For example, in some other embodiments, the first steel section 20 and the second steel section 21 may also be square tubes (not shown in the figure).

Thus, for the grille device 30 provided by this embodiment, by fixedly installing the clamping component 301 on the grille plate 10, the grille device 30 can be clamped with the grille fixing device, thereby improving the installation accuracy and convenience of the grille plate 10.

[0049] Preferably, the clamping component 301 includes a "return" shaped plate 3011, the "return" shaped plate 3011 is fixedly installed around the grille plate 10, and the thickness of the "return" shaped plate 3011 is less than the thickness of the grille plate 10. Thus, by setting the clamping component 301 into the structure of the "return" shaped plate 3011, the grille device 30 can be more conveniently clamped with the grille fixing device, and the pressure exerted by the grille filler 13 on the grille device 30 can be dispersed, which can improve the stress intensity of the grille device 30. By making the thickness of the "return" shaped plate 3011 less than the thickness of the grille plate 10, it is convenient for the grille plate 10 to be clamped with the grille fixing device.

[0050] Exemplarily, in one exemplary embodiment, the inner side of the cavity of the "return" - shaped plate 3011 is fixedly welded to the four sides of the grille plate 10. The side of the grille plate 10 in the length direction is clamped in the first clamping portion 201 formed between two first channel steels, and the side of the grille plate 10 in the width direction is clamped in the second clamping portion 211 formed between two second channel steels. It should be noted that the length direction of the grille plate 10 is the height direction of the vertical desulfurization tower (exemplarily, please refer to the following Figure 10 ).

[0051] It should be noted that, as can be understood by those skilled in the art, the present utility model does not overly limit the structure of the clamping assembly 301 provided on the grille plate 10, as long as the grille plate 10 can be clamped with the grille fixing device.
