Definitions

  • the present invention relates to a plate pack for the cold end layer of regenerative gas preheaters, wherein the plates are fixed in a holder by nesting, which consists of slotted carriers, wherein the carrier a plurality of extending from one edge and extending towards the opposite edge , Slots parallel to each other and spaced from each other, the plates have at least one longitudinal edge spaced apart slots and plates and carriers are inserted comb-like manner over the slots.
  • Gas preheaters have the purpose of preheating the gases required for combustion to improve the economy and to exploit the flue gas heat.
  • Regenerative gas preheaters are known in two versions: in Gasvor lockerrn with fixed storage mass rotate the supply hoods, while in Gasvor lockerrn with rotating storage mass a Schuvinenlie between fixed Gas ducts turn. The media are continuously fed without interruption of the gas flow in countercurrent.
  • the temperature of the cold gas side of the gas preheater is predominantly below the sulfuric acid dew point.
  • corrosive and erosive precipitates are formed, which form deposits to be removed in interaction with the solid cargo depositing on the clean gas side.
  • gas preheaters For constant cleaning of the heating surfaces, gas preheaters have structurally integrated blowing and flushing devices, which enable cleaning during operation.
  • incomplete cleaning results in increased pressure loss as the service life of the gas preheater increases due to solid deposits which resist cleaning with compressed air.
  • single-layer heating packages made of enamelled sheet steel with a so-called sacrificial layer are used as the cold end layer.
  • the expensive and sensitive heating elements can be protected against the high stress by installing the sacrificial layer on the cold side of the gas preheater, which consists of exchangeable plastic or enamelled steel packages.
  • the packages used as the cold end layer in this case consist, for example, of individual steel sheets or plastic sheets welded to one another at a distance from each other ( DE 103 20 462 B3 or DE 199 40 627 A1 ).
  • cracking in the area of the sheet steel or plate connections can occur due to the high chemical, thermal and mechanical material stresses in use. Such cracking is due to the embrittlement of the welds.
  • internal stresses caused by the welding heat can occur. This can ultimately lead to individual plates from the package solve, so that the protection of the heating packages is no longer guaranteed.
  • the present invention has for its object to provide a plate pack of the specified type, which has a particularly good fixation between plates and carriers in a simple structure.
  • a plate pack of the specified type in that the carrier are formed as a box-shaped slotted hollow beam, at the width of the slots of the plates are adapted to the plates below or above their slots have holes in the nested state of the Plates and hollow beams are disposed within the cavity of the hollow beams, and that the plate pack has holding rods which are inserted through the holes of the plates.
  • the hollow beams are first inserted with their slots in the slots of the plates. Thereafter, the support rods are passed through the holes of the plates and thus through the respective cavities of the hollow carrier used, so that the desired fixation or locking effect is achieved.
  • the slots of the box-shaped hollow beams preferably extend from one wall to the opposite wall thereof. In other words, they preferably extend over the entire height of the hollow beam, except for a wall thereof. As a result, the hollow carrier can be inserted relatively deep or far into the plate pack, so that a good fixation is achieved.
  • the hollow beams are curved on one side and flat on the opposite side.
  • the inserted support rod is preferably received by the curved portion, ie, the holes on the plates are arranged so that the guided through the holes holding rod comes to rest at the lowest point of the curved side of the hollow support.
  • the plates preferably have slots on both opposite longitudinal edges, wherein the slots can be arranged opposite or offset from one another at the opposite longitudinal edges.
  • the slots of the plates are preferably formed flatter than the slots of the hollow beams.
  • the depth of the slots of the plates expediently corresponds to the depth of a non-slotted wall of the hollow carrier, so that in the nested state, the hollow carrier with its outer surface flush with the edges of the plates.
  • the curved sides of the hollow carrier preferably point towards the plate interior, so that the flat sides or walls of the hollow carrier point to the outside of the plate package.
  • hollow carriers are arranged on both opposite longitudinal edges of the plates.
  • a support rod is guided by each hollow carrier in order to achieve a correspondingly good fixation.
  • the handrails are removed so that the hollow carriers can then be brought out of their slot engagement with the plates.
  • the inventively constructed plate package is preferably made of a suitable plastic, wherein the support rods may be made of metal. Without the implementation of welding operations a perfect fixation and plate carriers is achieved.
  • the support rods can be fixed in a suitable manner, for example, be attached to the two end plates of the plate pack. Such a fixation can be done for example by welding the support rods with the end plates.
  • the welding effort required for this purpose is much lower than in the above-described prior art.
  • the end plates need not be provided with holes in this embodiment, since the support rods are not through the end plates extend. If the support rods are to be guided by the end plates, the holes of the end plates are preferably laterally offset relative to the holes of the other plates and aligned in the fixing position to the holes of the other plates. By welding the end plates with the carriers in this case takes place a fix, in addition, the support rods can be fixed to prevent them from falling out.
  • the hole diameter and the diameter of the support rods may be adjusted so that the support rods are already held by frictional engagement in the plates.
  • the disk pack 1 shown in the figure is composed of a plurality of disks 2, a plurality of brackets 3, and a plurality of handrails 5. These parts are plugged together to create the plate pack, without welding joints are required.
  • the plates 2 have approximately a rectangular shape and have at their upper edge and at its lower edge a plurality of flat slots 6, which are arranged opposite one another. These slots 6 are spaced apart and serve to receive the corresponding carrier. Below the upper slots 6 and above the lower slots 6 are holes 7, wherein one hole 7 is associated with a slot.
  • the carrier 3 are formed as a box-shaped hollow carrier and have a flat wall 8 and an opposite curved wall 9. From the curved wall 9 extends from a plurality of parallel to each other and spaced apart slots 4 to the flat wall. 8
  • the carriers 3 are inserted with the curved wall 9 down from above and with the curved wall 9 upwards from below into the slots 6 of the plates 2. Since the slots 6 of the plates have a smaller depth than the slots 4 of the carrier 3, the carriers are inserted so far that their flat walls 8 come to lie in the slots 6 of the plates, the outer surfaces of the flat walls 8 flush with the upper and lower Complete the margins of the plates. It then arises the plate pack shown in the figure. In this position, the holes 7 of the plates are covered by the cavities of the supports 3, so that by pushing the holding rods 5 through the holes 7, the supports 3 are fixed in the position shown in the figure in the plate pack. By pulling the support rods 5 disassembly of the plate pack is possible.
  • the plate package 1 is held together by five carriers 3 at the upper edge of the plates 2 and five carriers 3 at the lower edge of the plates 2.
  • this number is not a limitation. Depending on the requirements, more or less carriers may also be used.
  • FIG. 2 shows an end plate 10 in the assembled state in both carriers 3.
  • the end plate 10 in FIG. 2 moved to the left so that they are in FIG. 3 illustrated position in which it is laterally offset relative to the other plates 2, as shown at 13.
  • the end plate 10 then passes into a fixing position, the in FIG. 3 and in which the holes 12 originally offset from the holes of the other plates occupy a position aligned with the holes of the other plates. In this position can now appropriate Handrails 5 are pushed through the holes.
  • the end plate 10 can be welded to the support 3 with these for fixing. An additional fixation of the support rods 5 can be done.
  • the end plate 10 need not have holes 12. If this is the case, the support rod 5 extends only through the inner plates and abuts, for example, against the end plate 10. By Versch redesignen the end plate 10 with the carrier 3 is then also achieved a fixation of the system.
  • FIG. 4 shows the end plate 10 in the welded state with the carrier 3, wherein a weld 14 is shown on the upper and lower support.
  • the end plate 10 also has laterally-widened slots, which are wider than the width of the carrier 3. It also takes place here a displacement of the end plate 10 in a fixing position in which the plate is welded to the carriers.
  • the end plate 10 closes flush with the other plates 2 with the fixing position. If handrails are to be passed through the end plate 10, the end plate is also provided with holes. Otherwise, the end plate has no holes, with the two end plates of the package supporting the handrails between them.
