Definitions

  • the invention relates to cleaning bodies for the internal cleaning of the tubes of tubular heat exchangers, in particular of steam power plant condensers, the cleaning bodies being carried in the cooling water flow and automatically pressed through the tubes by the cooling water flow and consisting of spherical or cylindrical sponge rubber elements adapted to the tube diameter and associated abrasive elements.
  • DE-A-2 026 502 discloses spherical cleaning bodies for cleaning pipelines with a diameter of up to over 1 m.
  • These cleaning bodies are made of an often cellular foam plastic and can have a denser surface made of the same material in order to make this surface more resistant to abrasion.
  • the cleaning effect of such a foam plastic ball is only limited, in particular in the case of heavily soiled pipe walls.
  • these bristles are inserted directly into the molds in which the sponge rubber elements are in turn produced by a spraying and blowing process.
  • the cleaning bodies according to the invention can be spherical or cylindrical. Depending on the length of the bristle shafts protruding from the sponge rubber element, the cleaning bodies are not only suitable for cleaning tubes with a circular inner diameter, but also for tubes which are oval, for example, or have a profiled wall.
  • the cleaning bodies shown in the figures are for cleaning the inside of the tubes of tube heat exchangers, in particular of steam power plant condensers, specifically for a cleaning method with recirculating operation of the cleaning bodies, the cleaning bodies being carried in the cooling water flow and being pressed automatically by the cooling water flow through the tubes.
  • the cleaning bodies consist of a sponge rubber element 1 adapted to the tube diameter and associated abrasive elements 2 and 3.
  • These abrasive elements 2, 3 are shown in the figures for exaggerated reasons because of the exaggerated illustration. According to the exemplary embodiment, they are designed as plastic bristles with bristle shaft 2 and fastening foot 3, and are anchored with their fastening foot 3 in the sponge rubber element 1 by foaming.
  • the plastic bristles are designed as U-shaped plastic monofiament sections.
  • the U-shaped web forms the fastening foot 3, while the U-legs of each of these abrasive elements form two bristle shafts 2.
  • the plastic bristles are nail-shaped, the nail head forming the fastening foot 3, so to speak.
  • FIGS. 2 and 4 A particularly advantageous embodiment is shown in FIGS. 2 and 4.
  • the plastic bristles are connected to a bristle carrier 3a.
  • the bristle carrier 3a carries the bristle shafts 2 on the outside in one row or in several rows. This bristle carrier 3a with the bristle shafts 2 is also foamed directly into the sponge rubber element during its manufacture.
