Definitions

  • the invention relates to a device for sealing retractable sootblower lances according to the preamble of claim 1.
  • a separate wall box is provided for each soot blower lance.
  • the labyrinth seal is usually used for sootblower lances that perform an axial or screwing movement.
  • a stuffing box seal is used instead of the labyrinth seal.
  • the invention has for its object to design the generic seal such that a wall box encloses several sootblower lances, which can also have different outer diameters.
  • the fins are arranged so that they provide the labyrinth seal, but at the same time allow each soot blower lance to move freely. Sootblower lances that are exposed to different cleaning media and have different diameters can thus be operated both independently of one another and together.
  • FIG. 1 An embodiment of the invention is shown in the drawing and is explained in more detail below.
  • the drawing shows the longitudinal section through a wall box with a seal according to the invention.
  • the only indicated wall 1 of a heat exchanger is provided with a passage opening 2.
  • the passage opening 2 is closed by a wall box 3, which is fastened tightly to the wall 1.
  • the wall box 3 is provided with a connection 4 for the supply of sealing air, which usually exits under pressure Flue gas from the heat exchanger prevented.
  • sootblower lances 5, 6 are guided into the wall box 3 and are charged with a gaseous cleaning medium such as water vapor or air or with a liquid cleaning medium such as water.
  • the sootblower lances 5, 6 are guided through the passage opening 2 into the heat exchanger for cleaning the tubes of the heat exchanger, whereby they perform an axially linear or screwing movement.
  • the sootblower lances 5, 6 are withdrawn into the wall box 3. It is also possible for one of the soot blower lances 5, 6 to protrude continuously into the heat exchanger and only perform a rotating movement during the blowing process.
  • the two sootblower lances 5, 6, which can have different outer diameters, are preferably acted upon with different cleaning media.
  • the sootblower lances 5, 6 are sealed with the aid of a labyrinth seal.
  • the labyrinth seal consists of several lamellae 7, 8, which are held on the outer edge with the aid of spacer rings 9.
  • the spacer rings 9 are guided on the outer wall of the wall box 3.
  • the slats 7, 8 are in pairs close to each other.
  • Each lamella 7 and 8 of a pair of lamellae tightly encloses one of the sootblower lances 5 and 6 and the other sootblower lance 6 and 5 with greater radial play. In this way, each sootblower lance 5, 6 with a full sealing effect by the fins 7, 8 has sufficient freedom of movement, which is required for trouble-free operation.
  • each soot blower lance 5, 6 can be sealed at the rear outlet from the wall box 3 by a gland seal.
  • This consists of a stuffing box packing 10 touching the soot blower lance 5, 6, which is surrounded by a housing 11 and can be tightened by means of screws 12 via a packing gland 13.
