Definitions

  • the invention relates to a heat exchanger suspended in a frame with a sootblower unit with the features of the preamble of claim 1.
  • sootblowers in which cleaning elements such as blowpipes or traverses are moved by an external drive part in the boiler, changes in position occur due to the thermal expansion relative to these guides, which lead to mechanical stiffness.
  • sootblowers it is sufficient to connect the front of the drive section directly to the wall of the heat exchanger. In this way, the soot blower follows the movements of the wall and the correspondingly moving suspension points for the guides in the heat exchanger.
  • a second suspension point at the rear end is required in addition to the front attachment, which is in turn connected to the wall of the heat exchanger with the aid of a pull rod.
  • the sootblower can maintain its position relative to the wall. So that small relative strains can be absorbed between the two fastening points on the wall, these and the rear suspension point on the soot blower drive part are often designed to be rotatable.
  • this suspension has the disadvantage that there must be sufficient space for long drive parts so that the pull rod can be guided to the wall. In practice, this often encounters difficulties, since the space above the soot blower is occupied due to other components such as scaffold girders, platforms, pipelines or the like.
  • the sootblower has also been suspended at the rear end with a rope that was guided over rollers and attached to the boiler wall so that the sootblower follows the thermal expansion.
  • this construction has proven to be relatively difficult and disadvantageous to implement. The problem is that the rope cannot be prevented from being fully prevented during operation, which necessitates constant readjustment of the suspension.
  • a change in position of the soot blower cannot be prevented by the movements of the pipeline connected to the blower valve, since the cable only absorbs tensile forces.
  • the invention has for its object to hang the soot blower unit so that it maintains its vertical position relative to the heat exchanger and takes up little space.
  • the soot blower unit consists of a lance tube 2, the z. B. connected to a blast traverse guided in the boiler and guided over an inner tube 4.
  • a blower valve 5 is provided, through which the Lance tube 2 is supplied with a blowing medium, for example water vapor, via the inner tube 4.
  • the lance tube 2 is displaced in the longitudinal direction and driven into the interior of the heat exchanger through a wall box 6 fastened to the wall 1.
  • the lance tube 2 of the soot blower unit is connected to a blower carriage 7 which is driven by a motor 8.
  • a pinion mounted on the output shaft of the motor 8 engages in a toothed rack 9 which is connected to a drive carrier 10.
  • the drive bracket 10 of the sootblower unit is articulated to the wall box 6 and is also suspended from a scaffold bracket 11 of a stationary scaffold via a lever linkage.
  • the heat exchanger is suspended in the frame so that it can move relative to the frame due to thermal expansion.
  • the lever linkage consists of two two-armed levers 12, 13 which are pivotable about a lever bearing 14, 15.
  • the two lever bearings 14, 15 are suspended from the scaffold support 11 with the aid of four vertical U-irons 16, which bear in pairs on two opposite sides of the levers 12, 13.
  • the two levers 12, 13 are preferably of the same length, and the lever arms formed on the levers 12, 13 also have the same lengths.
  • the two levers 12, 13 are connected to one another by a coupling joint 17.
  • the free end of the first lever 12 is held by a joint 18 fastened to the wall 1 of the heat exchanger.
  • the carriage 10 of the soot blower unit is articulated via rods 19.
  • the lever bearing 14 contains a bolt 20 which is held in a joint plate 21 connected to the lever 12.
  • the lever bearing 14 is displaceable by a certain amount in the longitudinal direction of the lever 12.
  • two horizontal U-irons 22 are attached to two vertical U-irons 16 connected to the scaffold support 11 at a vertical distance from one another, which reach under and overlap the bolt 20.
  • the horizontal U-irons 22 form a slideway between them is limited by the vertical U-iron 16 in the manner of an elongated hole and in which the bolt 20 can move.
  • the lever bearing 15 of the second lever 13 is in the same way, and the coupling joint 17 is constructed in a similar manner and is movable in the longitudinal direction of the levers 12, 13.
  • the horizontal shift that is possible in this way can be, for example, 30 mm.
  • a cross member 23 At the rear end of the scaffold bracket 11 is a cross member 23 and two guide rods 24 are vertically attached to this. These guide rods 24 rest on the long sides of the carriage 10 of the sootblower unit and secure the sootblower unit against tilting.
  • the forces causing such tilting originate, for example, from the pipe system which is connected to the blower valve 5.
  • the articulated fastening point of the drive carrier 10 and the joint 18 of the lever linkage also move downward together with the wall 1.
  • the joint 18 takes the first lever 12 downwards, as a result of which this lever 12 is inclined.
  • the second lever 13 assumes an opposite position, as a result of which the end of the second lever 13, which is articulated to the travel carrier 10, moves downward. Due to the set geometric relationships of the lever linkage, the path length covered by the joint 18 and the attachment point of the travel carrier 10 is equal to the path length described by the rear end of the second lever 13. This will move the sootblower unit parallel to itself.
  • a horizontal displacement resulting from the lever movement is absorbed by the displaceably arranged lever bearings 14, 15 and the displaceable coupling joint 17.
  • a transverse expansion of the heat exchanger, which takes up only a small amount, is absorbed by the play in the joints and the bearings.
