Description

Technical Field

[0001] The utility model relates to the technical field of garbage incinerator structures, in particular to a horizontal garbage incinerator superheater hanging device. Background Art

[0002] In a horizontal waste heat boiler for waste incineration, the superheater is usually arranged in the horizontal flue. Its hanging device will affect whether the superheater can operate safely and stably. The existing installation structure of the superheater is as follows: Figure 1 , Figure 2 As shown in the figure, the superheater header 2 and the superheater tube sheet 3 are hung on the box beam 11 through the hanging plate 12 and the hook 13, and the box beam 11 is supported on the water-cooled wall header 4.

[0003] The hanging device has high manufacturing precision requirements. During manufacturing, it is necessary to ensure that each hook 13 is at the same horizontal height, otherwise some tube segments will be in a stress-free state. At the same time, due to the cumulative error of the hook's transverse pitch and the error of the superheater header pipe joint pitch, the installation gap between the hanging plate 12 and the hook 13 during on-site installation cannot meet the design requirements. In actual operation, since the expansion of the superheater header 2 and the superheater tube segment 3 is greater than the expansion of the box beam 11, if the installation gap between the hanging plate 12 and the hook 13 is less than the design requirements, the expansion of the superheater header 2 and the superheater tube segment 3 will be blocked, affecting the safe and stable operation of the superheater, especially the high-temperature superheater, and even causing structural damage accidents in serious cases. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a horizontal garbage furnace superheater hanging device.

[0005] The utility model adopts the following technical solutions:

[0006] A horizontal garbage furnace superheater hanging device comprises a box beam, a hanging plate, a support plate and a limit plate, wherein a horizontally arranged support plate is fixedly connected to the inner side of the box beam, the hanging plate is hung on the support plate, and the limit plates are fixedly connected to both sides of each hanging plate on the support plate. The hanging device is supported on a water-cooled wall header, the superheater tube sheet is fixedly connected to the hanging plate, and the superheater header and the superheater tube sheet are supported by the hanging plate.

[0019] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0020] like Figure 4 The horizontal garbage furnace superheater hanging device shown in the figure includes a box beam 11, a hanging plate 12, a support plate 14, a limit plate 15, and a reinforcing rib plate 16. The hanging plate 12 is welded to the superheater tube segment 3, and the inner sides of the box beams 11 on both sides are respectively fixedly connected with horizontally arranged support plates 14, and limit plates 15 are welded on both sides of the hanging plate 12 on the support plate 14. The support plate is horizontally arranged to ensure that the support surface is at the same horizontal height.

[0021] A reinforcing rib 16 is welded to the support plate 14 below the position of the hanging plate 12 . The support plate 14 , the reinforcing rib 16 and the box beam 11 are connected by welding to improve the stability and bearing capacity of the device.

[0022] The distance between the limit plates 15 on both sides of the hanging plate 12 increases as it moves away from the expansion center, which solves the problem of expansion obstruction caused by expansion difference and ensures the safe and stable operation of the superheater.

[0023] The support plate 14 is a steel plate with a thickness ranging from 20 to 30 mm. The support plate is a whole thick steel plate, which is easy to manufacture.

[0024] The installation structure of the entire superheater is as follows Figure 3 and Figure 5 As shown, the inner sides of the box beams 11 on both sides are respectively fixedly connected with horizontally arranged support plates 14, the hanger plates 12 are hung on the support plates 14, the superheater header 2 and the superheater tube sheets 3 are connected by welding, the superheater tube sheets 3 are fixedly connected to the hanger plates 12, and the weight of the superheater header 2 and the superheater tube sheets 3 is supported on the support plates 14 of the superheater hanging device through the hanger plates 12.

[0025] As can be seen from the above, the support plate is set horizontally to ensure that the support surface is at the same horizontal height. The installation gap between the limit plate and the hanging plate increases as it moves away from the expansion center, thus solving the expansion obstruction problem caused by expansion difference. If the installation gap between the limit plate and the hanging plate does not meet the design requirements during on-site installation, it can be adjusted by cutting the limit plate without affecting the safety of the heat exchanger hanging device.

[0026] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
