Description

Technical Field

[0001] The utility model relates to the technical field of sulfuric acid waste heat recovery, in particular to a tube bundle slideway device of a sulfuric acid HRS steam generator. Background Art

[0002] The sulfuric acid production process generates considerable heat. The HRS steam generator, a core component of the dry absorption section's low-temperature waste heat recovery system (HRS), is a kettle-type, shell-and-tube, U-tube heat exchanger. As sulfuric acid plants continue to scale up, the tube bundles, their core components, are also growing larger and heavier. During equipment manufacturing, maintenance, and tube bundle replacement, using conventional tube bundle slides makes installing and removing the heavy tube bundles difficult and inconvenient. Therefore, to facilitate installation and removal without damaging the tube bundles, a tube bundle slide device is essential. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tube bundle slideway device for a sulfuric acid HRS steam generator, which can save effort when installing or extracting a heavy tube bundle into or from a shell, and avoid deformation or damage of the tube bundle due to excessive force.

[0004] To achieve the above purpose, a tube bundle slide device for a sulfuric acid HRS steam generator is designed, comprising a plurality of support plates arranged in parallel, wherein mounting grooves are respectively provided at the middle of the upper end and the lower end of the support plates, a roller is provided in the mounting groove at the lower end, mounting plates are respectively provided on the left and right sides of the roller, the lower end of the roller abuts against the slide rail, angle steel grooves are respectively provided on the left and right sides of the mounting groove, supporting angle steel is provided in the angle steel groove, angle steel slide rails are respectively provided on the left and right sides of the slide rail, and the supporting angle steel in the angle steel groove at the lower end is pressed on the angle steel slide rail.

[0005] The upper end of the angle steel slide rail and the lower end of the supporting angle steel are respectively welded with stainless steel plates.

[0006] The shapes of the installation groove and the angle steel groove are both rectangular.

[0007] The slide rail is an I-beam slide rail.

[0008] The upper end of the roller is provided with a top plate.

[0009] The outer edge of the support plate abuts against the steam generator shell.

[0010] The support plate is provided with a plurality of tube bundle passing holes.

[0011] The angle steel grooves on the left and right sides of the upper end and the angle steel grooves on the left and right sides of the lower end are symmetrically arranged.

[0012] Several parallel support plates are arranged at equal intervals.

[0013] Compared with the prior art, the utility model has a simple structure and reliable performance. When the tube bundle of the HRS steam generator is installed into or withdrawn from the shell, the rollers roll and rub, and the left and right angle steel tracks slide and rub and guide, which greatly reduces the workload of installing or withdrawing the tube bundle and avoids deformation or damage of the tube bundle due to excessive force.

[0016] Figure 3 It is a partial enlarged view of the lower end of the utility model. DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 3 As shown, mounting grooves 8 are respectively provided at the middle of the upper end and the lower end of the support plate 5, a roller 6 is provided in the mounting groove 8 at the lower end, mounting plates 9 are respectively provided on the left and right sides of the roller 6, the lower end of the roller 6 abuts the slide rail 2, angle steel grooves 11 are respectively provided on the left and right sides of the mounting groove 8, supporting angle steel 7 is provided in the angle steel groove 11, angle steel slide rails 3 are respectively provided on the left and right sides of the slide rail 2, and the supporting angle steel 7 in the angle steel groove 11 at the lower end is pressed on the angle steel slide rail 3.

[0019] Stainless steel plates 12 are welded to the upper end of the angle rail 3 and the lower end of the support angle 7 to reduce the friction coefficient of the sliding surface. This ensures smoother installation and removal of the HRS steam generator tube bundle. Furthermore, the stainless steel plates 12 cooperate with the angle rail 3 and the support angle 7 to provide guidance.

[0020] like Figure 1 As shown, the shapes of the mounting grooves 8 and the angle steel grooves 11 are both rectangular. Each support plate 5 is provided with angle steel grooves 11 symmetrically at four directions: lower left, lower right, upper left, and upper right. Support angle steels 7 are installed in the angle steel grooves 11, so that all support plates 5 are connected as one.

[0021] like Figure 3 As shown, the slide rail 2 is an I-beam slide rail.

[0022] A top plate 10 is provided on the upper end of the roller 6 to increase the contact area between the mounting plates 9 on both sides and the support plate 5 and enhance stability.

[0023] During specific use, a plurality of support plates 5 arranged in parallel are provided in the steam generator shell 1 , and the plurality of support plates 5 are arranged at equal intervals.

[0024] During use, the U-shaped tube bundle of the HRS steam generator passes through the tube bundle passage holes 4 of the support plate 5, with the outer edge of the support plate 5 abutting the steam generator shell 1. When the tube bundle is installed in or removed from the steam generator shell 1, the support plate 5 slides under the action of the rollers 6 and the angle steel rails 3. The angle steel rails 3 on both sides also serve as guides, greatly reducing the workload of installing or removing the tube bundle and preventing deformation or damage to the tube bundle due to excessive force.
