Definitions

  • the invention relates to a regenerative heat exchanger with a heat-exchanging storage mass provided with a multiplicity of flow channels and on the end face of a hood which divides the storage mass into at least one part with heat-emitting and one with heat-absorbing gases by means of radial sealing strips, which part is subjected to a continuous rotary movement between the storage mass and the hoods are alternately charged with the two gases, sealing gaskets also being arranged on the circumference between the hoods and a housing receiving the storage mass and the radial sealing strips being formed with sealing legs that interact directly with the flat end face of the storage mass as gap seals.
  • Such a regenerative heat exchanger is known from US-A-39 07 310.
  • the radial sealing strips are resiliently loaded in the direction of the flat end face of the storage mass, but do not rest with their sealing element on the end face of the storage mass, but are instead with the aid of circular spacers at a predetermined, slight distance from the end face of the storage mass held so that they act as gap seals.
  • the invention is based on the object of developing a regenerative heat exchanger of the type described at the outset in such a way that, while simplifying the construction and improving the sealing effect, the periodically necessary cleaning of the storage mass is eliminated.
  • the solution to this problem by the invention is characterized in that the sealing strips are provided over their entire length with a sealing element which is in direct contact with the storage mass and causes mechanical cleaning of the leading edges of the storage mass and which is formed by a multiplicity of bristles held in a supporting body and is bordered on the longitudinal edges of the sealing strips by the sealing legs, which consist of a material that is softer in relation to the material of the storage mass.
  • This configuration according to the invention not only improves the sealing effect, since in addition to the supporting bodies acting in the manner of a labyrinth seal, bristles which interact directly with the end face of the storage mass are provided, but also a permanent cleaning of the end face of the storage mass is achieved by the large number of bristles , so that the mechanical cleaning of the leading edges of the storage mass which is required at certain intervals in the known constructions can be dispensed with.
  • the resilient pressing of the sealing strips is achieved by utilizing the elastic material properties of the bristles.
  • These form a highly elastic element for both sealing and cleaning and are also able to adapt to unevenness in the end faces of the storage mass without damaging the storage mass.
  • the sealing legs which act in the manner of gap seals and which enclose the bristles held in the supporting body, consist of a material which is softer in relation to the material of the storage mass, the sealing legs can be brought closer to the end face of the storage mass without the risk of damage the storage mass exists.
  • the bristles held in the support body and possibly the sealing legs can be replaced in a simple manner.
  • Another advantage of the configuration according to the invention is that the sealing strips according to the invention represent a negligibly small impediment to the flow for the two heat-exchanging gases.
  • the design according to the invention can be used in particular on regenerative heat exchangers for heating the clean gases behind desulfurization systems and for air preheating, and in general in regenerative heat exchangers with strongly contaminating leading edges of the storage mass.
  • the storage mass 1 provided with a large number of flow channels stands still, whereas the hood 2, which is shown at a distance from the flat end face of the storage mass 1, is driven in rotation due to the better visibility.
  • the hood 2 which is shown at a distance from the flat end face of the storage mass 1
  • the hood 2 is provided with radially extending sealing strips 3.
  • four sealing strips 3 each running over the length of the radius are provided, which are arranged in the manner of a cross and each form two channels opposite one another with respect to the center of rotation, on the one hand for the heat-emitting gas and on the other hand for the heat-absorbing gas.
  • the circular arcs present between each two radially running sealing strips 3 on the circumference of the hood 2 are also provided with seals 4, which in the exemplary embodiment are composed of individual pieces.
  • the radially extending sealing strips 3 rest directly against the respective flat end face of the storage mass 1.
  • the sealing strips 3 have an inherently elastic sealing element 6, which is formed by a plurality of bristles held in a support body 5. These bristles are bordered on the longitudinal edges of the sealing strips 3 by sealing legs 7 designed as gap seals.
  • These sealing legs 7 consist of a material that is softer in relation to the material of the storage mass 1, so that their edges facing the storage mass 1 can be brought relatively close to the storage mass 1 without the risk of damage to the storage mass 1.
  • a good sealing effect is achieved by the sealing leg 7, which is supported by the bristles of the sealing element 6.
  • the sealing legs 7 are arranged on a support profile 8 together with the support body 5 and the bristles 6.
  • This support profile 8 8 is arranged on an end profile 9, which in turn is fastened to a chamber profile 10 of the hood 2 formed from two U-profiles.
  • the seals 4 arranged on the circumference of the hood 2 are formed in the manner described with reference to FIG. 2 from a support body provided with bristles.
  • the sealing strips 3 and the seals 4 it is possible to design the sealing strips 3 and the seals 4 differently, since only the sealing strips 3 are to produce a cleaning effect in addition to their sealing function.
