Description

Technical Field

[0001] The invention relates to the technical field of waste heat boiler module structures, and in particular to an externally insulated vertical waste heat boiler module and a guard plate integrated structure. Background Art

[0002] Gas-steam combined cycle has become one of the most important power generation technologies in the world. Many oil-rich countries in the Middle East have begun to build a large number of combined cycle units. Against this background, waste heat boilers with external insulation came into being. At present, the general operation is that conventional modules need to design a separate transportation frame, and the module and the transportation frame are assembled before leaving the factory. The guard plate is shipped separately, which increases the design work and manufacturing costs, and the workload of on-site installation is large. Summary of the invention

[0003] In order to solve the existing problems of high cost and large on-site installation workload, the present invention provides an external insulation vertical waste heat boiler module and guard plate integrated structure, which can effectively reduce the manufacturing cost and reduce the on-site installation workload.

[0004] The technical solution is as follows: an externally insulated vertical waste heat boiler module and guard plate integrated structure, which includes a left guard plate, a right guard plate, and a module tube plate, characterized in that U-shaped areas are respectively arranged on the left guard plate and the right guard plate at intervals, and the left guard plate and the right guard plate are connected to the module upper support seat at the upper end and the module lower support seat at the lower end in the U-shaped area. Widened areas are arranged at both ends of the module tube plate and are respectively connected to the module upper support seat and the module lower support seat, and the left guard plate and the right guard plate are connected by a pull rod arranged in an X shape.

[0005] Its further feature is that the pull rod comprises a first pull rod of a whole section and two second pull rods of a segmented section, the two second pull rods are connected by a connecting plate, and the first pull rod is provided with a through hole for the connecting plate to pass through;

[0006] The upper end of the module lower support seat is provided with a first mounting hole for fixedly connecting the lower end of the module tube sheet and is provided with a first bolt and a first nut;

[0007] The lower end of the module upper support seat is provided with a second rotation hole for fixedly connecting the upper end of the module tube plate and is provided with a second bolt and a second nut;

[0008] Channel steel is arranged inside the left guard plate and the right guard plate, a horizontal steel plate is welded and fixed on the channel steel, and the brace is connected to the horizontal steel plate;

[0009] A flat plate connected to the upper end of the channel steel is arranged on the upper support seat of the module, and the lower end of the channel steel is connected to the convex plate on the inner wall of the left guard plate or the right guard plate.

[0010] After adopting the present invention, compared with the existing conventional design, the integrated structure of the module tube plate and the left and right guard plates eliminates the module transportation frame when leaving the factory, reduces the design work and manufacturing costs, and greatly reduces the workload of on-site installation.

[0018] See Figures 1 to 7 As shown, an externally insulated vertical waste heat boiler module and guard plate integrated structure includes a left guard plate 1, a right guard plate 2, and a module tube sheet 3. U-shaped areas 4 are arranged on the left guard plate 1 and the right guard plate 2 at intervals and correspondence. The left guard plate 1 and the right guard plate 2 are connected to the module upper support seat 5 at the upper end and the module lower support seat 6 at the lower end at the U-shaped area 4. Widened areas 7 are arranged at both ends of the module tube sheet 3 and are respectively connected to the module upper support seat 5 and the module lower support seat 6. The widened area 7 is used for hanging the module tube sheet 3, which is significantly different from the conventional module tube sheet. The left guard plate 1 and the right guard plate 2 are connected by a pull rod arranged in an X shape to eliminate the influence of the positive pressure inside the boiler.

[0019] The pull rods include a first pull rod 8 of a whole section and two second pull rods 9 of a segmented section. The two second pull rods 9 are connected by a connecting plate 10 . The first pull rod 8 is provided with a through hole for the connecting plate 10 to pass through.

[0020] A first mounting hole 11 for fixing the lower end of the module tube sheet is opened at the upper end of the module lower support seat 6, and a first bolt 12 and a first nut 13 are provided; a second mounting hole 14 for fixing the upper end of the module tube sheet is opened at the lower end of the module upper support seat 5, and a second bolt 15 and a second nut 16 are provided.

[0021] Channel steel 17 is arranged inside the left guard plate 1 and the right guard plate 2 , a horizontal steel plate 18 is welded and fixed to the channel steel 17 , and a tie rod is connected to the horizontal steel plate 18 .

[0022] A flat plate 19 connected to the upper end of the channel steel 17 is provided on the module upper support seat 5 , and the lower end of the channel steel 17 is connected to the convex plate on the inner wall of the left guard plate 1 or the right guard plate 2 .

[0023] The upper support seat 5 and the lower support seat 6 of the module are placed in the U-shaped area 4, which play the role of connecting the module tube sheet 3 with the left guard plate 1 and the right guard plate 2, and also play a supporting role. When hoisting the module on site, the upper support seat 5 and the lower support seat 6 of the module need to be removed and replaced with a hoisting rod.
