Definitions

  • the invention relates to an industrial chimney with a chimney shaft, which has at least one flue gas duct, chimney head and acid protection devices.
  • Industrial chimneys refer to tall chimneys, as are used in particular in power plants, waste incineration plants and the like.
  • the flue gases carry water vapor and such ions as well as compounds which are absorbed by the water vapor upon condensation and form disturbing acids. Condensation of the water vapor can occur depending on the temperature conditions. Depending on the wind conditions, the condensed water vapor with the substances it has absorbed is deposited on the chimney. Special acid protection devices against this so-called acid condensation are required.
  • the chimney head is a brick building and the acid protection device mostly consists of an outside coating of the chimney head made of a suitable, acid-resistant coating material, e.g. B. based on epoxy resin.
  • a suitable, acid-resistant coating material e.g. B. based on epoxy resin.
  • the protective effect achieved is often unsatisfactory because the coating can be infiltrated by the acid condensate.
  • the short service life of the acid protection device designed as a coating and thus the time-limited acid protection effect interfere.
  • the acid protection device is also known (P 40 18 917.1-25, PatG ⁇ 3 (2)) to design the acid protection device as a nozzle casing which forms an aerodynamic annular gap around the chimney head, the nozzle ring gap being open at the bottom and in the region of the mouth of the chimney.
  • the nozzle jacket can consist of single-layer or multi-layer glass panes. The measures known so far have proven their worth. The assembly of the nozzle jacket is complex, particularly when the nozzle jacket is constructed from glass panes.
  • the invention has for its object to provide an industrial chimney of the basic structure described above, which can be set up and assembled in a simple manner and is characterized by a long service life.
  • the invention teaches that the chimney head is simultaneously designed as an acid protection device and is constructed from glass elements that form an acid protection duct, and that the acid protection duct is placed on the chimney shaft as an extension of the flue gas duct.
  • the invention is based on the knowledge that it is not necessary in an industrial chimney of the structure described above to attach the acid protection device as a coating or as a special structure on the chimney head, that the chimney head itself with little effort as an acid-resistant structure can be carried out, which meets all requirements if it is constructed from glass elements in the manner described. You can work with all types of glass common in the construction industry. The structure of the chimney head glass elements can always be designed relatively easily.
  • the chimney head produced as an acid protection device in the form of an acid protection duct or in the form of several acid protection ducts in the form of adjacent tubular structures has only a relatively low height and in relation to the absorption of wind forces a favorable diameter / height ratio, so that special measures for the absorption of these wind forces are not necessary and the connection to the chimney shaft can be carried out as a simple anchoring or bracing.
  • the acid protection channel can have an outer wall made of glass elements and a heat insulation layer connected on the inside. Chimneys or flue gas ducts with a heat insulation layer are known per se (DE-OS 33 40 109), but on the outside.
  • the thermal insulation layer consists of suitable thermal insulation materials. But there is also the possibility of making the arrangement so that the acid protection channel has an outer wall made of glass elements, an inner wall made of glass elements and a thermal insulation space between the inner wall and the outer wall.
  • the thermal insulation space can be designed as a closed space, for. B. overall in the manner of a heat insulating glass unit.
  • the thermal insulation space is filled with a thermal insulation material. It is within the scope of the invention in all embodiments of insulating glass units designed as heat-insulating glass elements to use, as they are common in other areas of the construction industry, such as windows. It is also within the scope of the invention to heat the glass elements or the acid protection channel. Depending on the climatic conditions, the thermal insulation or the heating are advantageous for avoiding acid condensation inside the chimney head designed as an acid protection duct.
  • the design of the building which according to the teaching of the invention represents the acid protective jacket made of glass elements
  • a frame structure made of frame bars can be built, which has glass elements inserted into the frame or placed on the frame.
  • the acid protection channel is designed as a self-supporting structure made of glass elements. Self-supporting means that the glass elements themselves also form the supporting structure.
  • composite elements are designed statically and in terms of stability according to the rules of architecture and form a shell or shells in the static sense.
  • they are combined with the aid of composite elements only in such a way that they form a unit statically and in terms of stability.
  • the composite elements are the usual in glass construction Profiles and auxiliary elements, e.g. B. Combinations of clamping profiles and cover profiles. Of course, they consist of a suitable, acid-resistant material.
  • the glass elements can be designed as flat glass panes and, with the interposition of composite components, combined to form an acid protection channel to form a polygonal plan.
  • the glass elements are designed as segmented curved glass panes and are assembled with the interposition of composite components to form an acid protection channel with a circular plan.
  • Safety glass panes e.g. B. composite security washers or thermally or chemically prestressed security washers.
  • the acid protection channel and thus the glass elements can be mechanically prestressed in the axial direction and / or in the circumferential direction with the aid of prestressing traction means for reasons of stability and stability. It is possible to prefabricate the acid protection duct or the acid protection ducts completely or, for example, in the form of rings on the floor, so that only the final assembly takes place on the chimney.
  • the basic structure of the industrial chimney 1 shown in the figures consists of a chimney shaft 2, which has at least one flue gas duct 3, the chimney head and an acid protection device 4.
  • the chimney head is at the same time designed as an acid protection device 4 and is constructed from glass elements 5 for this purpose.
  • the glass elements 5 form an acid protection channel 6 or a plurality of acid protection channels.
  • the acid protection duct 6 or the acid protection ducts are placed on the chimney shaft 2 as an extension 7 of the flue gas duct 3 or the flue gas ducts.
  • the acid protection channel 6 has an outer wall 8 made of glass elements 5, an inner wall 9 made of glass elements 5 and between the inner wall 9 and outer wall 8 a thermal insulation intermediate space 10.
  • the thermal insulation intermediate space 10 is made of a thermal insulation material 11 filled out. It is connected on the top and bottom. - The filled in the thermal insulation space 10 thermal insulation materials 11 are selected and can be arranged so that they contribute to the statics and stability of the acid protection channel 6 or the acid protection channels.
  • the acid protection channel 6 as a whole is designed as a self-supporting structure made of the glass elements 5.
  • the glass elements 5 are segmented curved glass panes which, with the interposition of composite components 12, are assembled to form an acid protection channel 6 with a circular plan. They could also be composed of flat glass panes with a polygonal plan, as indicated by dash-dotted lines in FIG. 3.
  • Fig. 1 it can be seen that the acid protection channel 6 is connected to the chimney shaft 2 by anchoring 13, which was only indicated in Fig. 1 and can be done with the usual anchoring means.
  • the acid protection channel 6 and thus the glass elements 5 can also be mechanically prestressed in the axial direction and / or in the circumferential direction with the aid of tensioning means (not shown).
  • a comparison of FIGS. 5 and 6 shows how the glass elements 5 are connected to one another. Profiles can be seen which are designed as clamping profiles 14 and as cover profiles 15. Sealing means 16 can also be provided.
