Definitions

  • the invention relates to a device for cleaning flues of a boiler system with a cleaning hose which can be inserted through an access in a flue.
  • the invention relates to a method for cleaning flues of a boiler system with a cleaning hose, wherein the cleaning hose is unrolled from a hose storage and is introduced through an opening in a flue.
  • the invention relates to a method for cleaning the Leersee a boiler.
  • the Leerman or so-called radiation trains are designed as gas-tight welded membrane wall construction and are used in boiler systems as heat exchanger surfaces.
  • the fly ash transported in the flue gas is partly fixed during operation on the membrane walls of the Leerman and can develop in the course to hard caking. The result is a reduced heat exchange across the membrane walls, which leads to the rise of the flue gas temperature and the resulting reduction in the efficiency of such a thermal power plant. Since the salts present in the adhering contaminants react corrosively with the steel, the cleaning of the membrane walls also provides increased protection against corrosion.
  • the cleaning hose is unrolled by a drum-type hose store manually or motorized and led to an opening in the ceiling of the boiler system. There, the hose is inserted into an opening through which the hose is led to the flue. This is laborious and time consuming.

  • the device has a cleaning hose delivery module, with which the cleaning hose from the hose storage into the hose guide, which extends between the ceiling of the boiler and a platform, is pushed.
  • hose guide has a vertical and a horizontal direction component, a hose can be pushed not only in the hose guide vertically down into the boiler but it can be the inputs of Hose guides are arranged on a line or a bend, while the openings in the boiler ceiling are not arranged in a line or a curve.
  • Pushing the cleaning hose makes it possible to also use bends greater than 30 ° with a bending radius of at least 500 mm for the hose guide. It is advantageous if the hose guide also has bends of less than 45 ° and preferably even less than 40 °. Thus, more acute-angled bends are possible than before.
  • hose drum is arranged horizontally. This makes it possible to arrange the hose storage above the platform even in limited space.
  • the cleaning hose delivery module allows the cleaning hose to be removed from the hose reel at a defined constant speed and inserted into the hose guide so that the hose can be conveyed automatically from the hose repository to the flue gas flue.
  • the cleaning hose delivery module is arranged immediately in front of the hose guide. This makes it possible to push the flexible cleaning hose by means of the makeschlauchtomoduls in the hose guide to thereby promote him through a long tubular hose guide to the flue. In particular, the hose can thus be pushed into the hose guide to guided in the hose guide to find the way to the opening and in the flue. This is particularly advantageous for long hose guides.
  • An advantageous embodiment provides that the cleaning hose delivery module has prestressed pressure rollers by means of spring force. Thus, the cleaning hose can be conveyed gently and effectively.
  • the speed of the cleaning hose driven by the cleaning hose delivery module is controlled by a feed drive.
  • a constructional embodiment provides a cleaning hose positioning device, which guides the cleaning hose on a defined path to a plurality of hose guides. This makes it possible with the cleaning hose positioning device to bring the cleaning hose to a hose guide and stop there, so that the hose can be unwound from the hose storage and inserted into the hose guide.
  • the path of the cleaning hose positioning device is preferably located on a circular line.
  • the cleaning hose positioning device has a cleaning hose holding arm, which is laterally displaceable or pivotable, in order to position the cleaning hose along a plurality of line guides arranged on a line.
  • An advantageous embodiment provides that the Schlautivs issued is attached to the cleaning hose delivery module and can be connected to the hose guide. This makes it possible to provide a single hose cleaning device on the cleaning hose conveying module and to clean the cleaning hose with the same hose cleaning device when pulling out the cleaning hose from different flue gas flaps.
  • the object underlying the invention is also achieved with a method for cleaning flues of a boiler plant with the features of claim 15.
  • the tubular tube guide is flushed with a lubricant before, during or after the cleaning tube is pushed into the tube guide.
  • This lubricant is water in the simplest case.
  • the slip properties of the water may also be enhanced by surfactants or other chemicals, or hydrophobic substances may be used.
  • FIGS. 1 and 2 schematically show how in a device 1 for cleaning flues of a boiler plant 2 a marketsschlauchpositionier adopted 3 a cleaning hose 4 to several hose guides 5, 6, 7, 8, 9 and 5 ', 6', 7 ', 8', 9 'leads ,
  • the tube guides 5 to 9 lie on a straight line 10, while the tube guides 5 'to 9' lie on a circular line 11.
  • the cleaning hose positioning device 3 has long since the direction of the arrow 12 of the arrow on a straight path slidable to guide the cleaning hose 4 to the hose guides 5 to 9.
  • the cleaning hose positioning device 3 ' has long been pivotable about a point 14 of the arrow 13 in order to guide the cleaning hose 4' to the hose guides 5 'to 9'.
  • FIG. 3 shows the marketsschlauchpositionier issued 3 which stands with a base 15 on a platform 16.
  • the base In a linear arrangement of the base is connected to a kind of rail system, so that the starsschlauchpositionier Anlagen 3 moves in an axis.
  • this base 15 In the case of a semicircular arrangement of the nozzle 17 of the hose guides 5 'to 9', this base 15 is rotatably mounted. The rotation of the Cleaning hose positioning device 3 'via a geared motor flanged to the frame until the position above the desired nozzle 17 is reached.
  • a hose reel 37 is arranged as a hose repository 18 and by means of the cleaning hose conveying module 19 the cleaning hose 4 is guided to a hose guide 5 to 9.
  • the cleaning hose conveying module 19 is arranged directly in front of the hose guide.
  • the cleaning hose conveying module 19 has a feed roller 20 with a circumferential groove 21, in which the hose 4 is guided.
  • the tube 4 can be held in the groove 21, so that a circumferential force of the roller 20 upon rotation of the roller 20 transmits to the tube 4. It is advantageous if several pressure rollers 22 to 25 press the tube into the groove 21.
  • FIG. 4 shows a hose cleaning device 26.
  • a nozzle 27 is arranged, which can be pushed through the hose cleaning device 26 and through the nozzle 17 in the hose guide 5. The nozzle 27 then passes into the boiler system 2 and there into the flue 28 to clean there heat exchanger surfaces and membrane walls.
  • the hose 4 When driving in and pulling out the nozzle 27, the hose 4 comes into contact with flue gases. As a result, the cleaning hose 4 with its typical metal fabric as a protective outer shell transports a considerable amount of fly ash when it is pulled out of the interior of the boiler. This can lead to contamination on the slide 29, the nozzle 17 and the hose reel 37 of the hose accumulator 18. Also, the cleaning hose delivery module 19 is through such contamination affected. Therefore, with the hose cleaning device 26, the hose 4 and possibly also the nozzle 27 are cleaned.
