DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment: Reference Figure 1 As shown in the figure, the carbon-removing fan air duct soft connection structure comprises galvanized soft plates 2 and silica cloth 5 arranged on one of the base air duct units 1 close to the fan, and the base air duct unit 1 is connected with the first section of the special-shaped carbon-removing fan air duct unit at the air inlet end of the fan.

[0025] Specifically, the base air duct unit 1 is divided into an upper half air duct unit and a lower half air duct unit, the surfaces of the upper half air duct unit and the lower half air duct unit are coated with a conventional rust-proof and corrosion-proof coating, the upper end of the upper half air duct unit is connected with other air duct units through a first connecting flange 6, the lower end of the lower half air duct unit is connected with the fan through a second connecting flange 13, two galvanized soft plates 2 are arranged, and the two galvanized soft plates 2 are connected with the upper and lower ends of the silica cloth 5, specifically, the galvanized soft plates 2 and the silica cloth 5 are connected in a mechanical buckling mode, the upper end of the galvanized soft plate 2 on the upper side of the silica cloth 5 is sealingly fixed between the upper half air duct unit, the lower end of the galvanized soft plate 2 on the lower side of the silica cloth 5 is sealingly fixed between the lower half air duct unit, and specifically, the galvanized soft plates 2 and the base air duct unit 1 are fixed through sealing gaskets 3 and countersunk screws 4, wherein the sealing gaskets 3 are fire-retardant self-adhesive gaskets, and preferably have a width of 40 mm, a thickness of 5 mm, and a length of 1880 mm, and the countersunk screws 4 are made of stainless steel.

[0026] The above soft connection structure can eliminate the force on the fan, but cannot eliminate the deformation of the carbon removal fan air duct, which has great safety hazards. Therefore, an auxiliary support structure is further included, which is fixed between the first connecting flange 6 and the ground. Specifically, the auxiliary support structure includes a support steel column 7 and a support carbon steel plate 8. The height of the support steel column 7 is consistent with the vertical height of the first connecting flange 6, and the support steel column 7 is preferably a galvanized steel pipe. The bottom of the support steel column 7 is fixed with a support carbon steel plate 11, and the support carbon steel plate 11 is fixed to the ground by anchor bolts 12. The top end of the support steel column 7 is fixed with the support carbon steel plate 8, and the support carbon steel plate 8 is fixed with the first connecting flange 6, thereby increasing the stress surface and supporting the carbon removal fan air duct. In addition, a diagonal bracing plate 10 is fixed between the bottom surface of the support carbon steel plate 8 and the outer wall of the upper half air duct unit, further enhancing the support effect.

[0027] Optionally, a set of auxiliary support structures can be installed on both sides of the first connecting flange 6 to further increase the stress surface and further enhance the auxiliary support effect on the carbon removal fan air duct.

[0028] It should be noted that the distance between the upper half air duct unit and the lower half air duct unit is less than the sum of the widths of the silica cloth 5 and the two galvanized soft plates 2. For example, the widths of the galvanized soft plates 2 and the silica cloth 5 are 70mm and 144mm respectively, and the total width of the soft connection structure is 284mm. The distance between the upper half air duct unit and the lower half air duct unit of the basic air duct unit 1 is slightly less than 284mm, for example, 270mm.

[0029] To ensure the rigidity and flexibility of the galvanized soft plate 2, the galvanized soft plate 2 is preferably 0.5mm thick, 70mm wide, and 1880mm long.

[0030] Compared with a single-section carbon removal fan air duct with all soft connection structures, the soft connection structure in the present scheme uses less, and accordingly, its cost is lower. In addition, the single-section soft connection structure needs to be supported internally, otherwise the soft connection is easy to break. The soft connection structure in the present scheme has a small stress area and does not need internal support, and is less likely to be damaged. In addition, the single-section carbon removal fan air duct needs to be disassembled for maintenance, and the present scheme only needs to unscrew the socket head screw 4 to directly detect the fault point. Daily maintenance is more convenient.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
