Definitions

  • the invention relates to a device for cleaning a flue of a combustion system.
  • a device for cleaning a flue in which a hose is guided from above into the flue.
  • the hose is rolled up on a hose reel.
  • the hose reel In order to guide the hose further in the vertical direction into the flue, the hose reel is rotated about its axis so that the hose unrolls from the hose reel.
  • a nozzle head At the end of the hose in the flue, there is a nozzle head with several nozzles pointing in different directions.
  • the nozzles serve to inject water, which is passed through the hose to the nozzle head, against inner walls of the flue gas duct or pipes located therein. The impingement of the water jets should clean the surfaces in question.
  • the height of the nozzle head in the flue gas duct is varied during the cleaning process.
  • the nozzle head is rotatably connected to the hose.
  • a driven by the flow of water impeller sets the nozzle head by means of a gear in rotation.
  • Impeller and gearbox are arranged in the nozzle head. The rotation of the nozzle head ensures that the inner walls of the flue are completely cleaned in a horizontal plane.
  • a failure of the impeller or the gear in the nozzle head can have serious consequences.
  • the nozzle head can not turn anymore.
  • the stationary in their direction, exiting from the nozzle head water jets apply individual areas of the inner surfaces of the flue selectively over a longer period of time with water. This can lead to major damage to the relevant points of the flue gas train or the pipes laid therein, especially as a failure of the impeller or the transmission is not recognized during the cleaning process in the rule.
  • the Umlenkdüse Due to the rotationally symmetrical structure of the Umlenkdüse enters a jet of water from the nozzle head, which is equal to or equal to all sides.
  • a non-circular flue for example in a cuboid flue, the inner surfaces are cleaned with a rotationally symmetrical water jet so different degrees.
  • the distance between the nozzle head and surface to be cleaned varies depending on the structural design of the flue gas outlet.
  • narrow flue gas trains can the Distance between the nozzle head and the longitudinal side must be much smaller than the distance between the nozzle head and the narrow side.
  • the adjustment of a water pressure on the one hand ensures sufficient cleaning and on the other hand does not damage the flue, is not possible or very difficult.
  • the flue can have pipes, viewing windows and other fixtures that require special cleaning and for an all-round cleaning with rotationally symmetrical water outlet from the nozzle head is not suitable.
  • the invention is based on the object to provide a device for cleaning a flue, which works efficiently, largely excludes damage to the flue, requires a small footprint and can be easily used in existing incinerators with flues.
  • the object is achieved by providing a device having the features of claim 1.
  • the hose reel is mounted such that it can be rotated at least about a first axis corresponding to the drum axis and about a second axis.
  • the rotation about this second axis which is not parallel to the drum axis, causes the hose or the hose part, which is located in the flue during the cleaning process, to be rotated about its longitudinal axis.
  • the nozzle head is rotatably connected to the hose, so that by rotating the hose reel about the second axis of the nozzle head in the flue is also rotated.
  • the hose drum By rotating the hose drum about the first axis, that is to say about the drum axis, the hose is unwound or rolled up so that the position or position of the nozzle head in the flue can be varied simultaneously with the rotation of the nozzle head. If the hose is guided from above into the flue, the vertical height and the angle of rotation of the nozzle head in the flue can be adjusted.
  • the rotation of the nozzle head can be specified by rotation of the hose drum about the second axis exactly. This opens up the possibility of predetermining the direction of a cleaning jet emerging from the nozzle head by rotation of the hose drum.
  • a pinpoint cleaning of individual surface elements in the interior of the flue is possible.
  • the geometry of the flue, in particular the distance between the nozzle head and surface to be cleaned, located in the flue gas internals and possibly a different degree of contamination can be considered in the cleaning such that the time and / or frequency with which a cleaning jet to a certain Surface meets, is adjusted individually.
  • water is used as the cleaning medium.
  • the hose reel is held by a drum carrier.
  • the hose reel may rotate about the first axis.
  • the drum carrier in turn is rotatably mounted about the second axis. By rotation of the drum carrier thus attached to the hose nozzle head is rotated about the longitudinal axis of the hose.
  • the first axis and the second axis are perpendicular to each other.
  • the drum axis lies in the horizontal and the second axis in the vertical.
  • the hose in the flue gas through an opening with a substantially vertical axis can be introduced, which is coaxial with the second axis of the hose drum or to the axis of rotation of the drum carrier.
  • the preferably heat-resistant tube which is flexible in the longitudinal direction, but torsionally stiff, can thus be easily guided into the flue without this must be bent unnecessarily.
  • the rotation of the hose reel is controlled about the first and second axes. Due to the given geometric conditions (eg diameter of the hose drum, distance of the hose drum to the flue), the position (with vertical hose hanging hose) and the rotation angle position of the nozzle head can be controlled by controlling the rotations of the hose drum. With known geometry of the nozzle head (eg arrangement and direction of the nozzles), it can thus be determined how long and at what frequency certain areas inside the flue gas pass are cleaned. For example, particularly heavily contaminated areas can be subjected to a water jet longer and more frequently, while other areas can be left out completely if required.
  • known geometry of the nozzle head eg arrangement and direction of the nozzles
  • the pressure of the water (the cleaning medium) in the hose or in the nozzle head can be regulated.
  • the pressure can be reduced when a jet of water strikes a surface which lies in the vicinity of the nozzle head. If, however, a surface further removed from the nozzle head is to be cleaned, the setpoint for the pressure can be increased.
  • each surface element in the flue which can be achieved by a jet of water of the nozzle head, individually cleaned in terms of pressure, time and frequency.
  • a control unit of the cleaning device may comprise a memory which stores setpoint values for the rotational movements of the hose reel and also for the pressure value of the cleaning medium. By comparing these setpoints with actual values, which are detected for example by a water pressure measurement, a hose length measurement and a rotational angle measurement for the drum carrier, an automatic operation of the device according to the invention is possible.
  • a first servomotor may be provided.
  • a second servomotor can be used to rotate the hose reel about the second axis.
  • the two servomotors can be controlled by the control unit according to the setpoint specifications.
  • the nozzle head may have a plurality of nozzles.
  • the nozzles are arranged such that the reaction forces of the exiting through the nozzle cleaning medium in a horizontal plane compensate.
  • This can for example be achieved in that the nozzle head has a plurality of circumferentially equally spaced nozzles which are directed radially outward.
  • the axis of a nozzle can also have a vertical component in the operating position of the nozzle head.
  • the hose reel can be endlessly rotatable about the second axis, that is, the hose reel can rotate around the second axis as often as desired.
  • the hose reel may be rotatable about the second axis only in a certain angular range, for example in an angular range of 180 degrees.
  • a certain angular range for example in an angular range of 180 degrees.
  • at least two nozzles are provided, which are arranged diametrically in the nozzle head. If the hose reel is rotated back and forth in the specified angular range, the two nozzles together cover an angular range of 360 degrees, so that a flue is cleaned all round in a hanging hose in a horizontal plane can.
  • Another embodiment provides an angular range of 90 degrees with the nozzle head including at least four nozzles.
  • a device for guiding or holding the nozzle head may be provided on the nozzle head or on one end of the hose.
  • the nozzle head in this case has an eye, by means of which a rope or the like can be attached to the nozzle head.
  • the hose By means of the cable which pulls the nozzle head in a predetermined direction with a preferably adjustable force, the hose can be held in a desired position and, as far as the control of the hose reel permits, be guided on a desired path. It is thus possible, for example, to hold a hose, which is led horizontally into the flue gas duct through a lateral opening, by the tension of the cable in the horizontal plane.
  • the 1 shows a device 1 for cleaning a flue 2.
  • the flue 2 is here shown schematically only as a cuboid.
  • the device 1 is arranged with a hose drum 4, on which a hose 5 is partially rolled up.
  • the hose 5 is guided through an opening 6 of the flue 1.
  • the hose is made of heat-resistant material and can not be twisted in its longitudinal direction or only insignificantly.
  • a nozzle head 8 is rotatably attached at one end 7 of the tube 5, which is located in the flue 1.
  • the task of the nozzle head 8 is to conduct a cleaning medium, preferably water, which is passed through the tube 5 in the flue 1, on internal walls 9 of the flue 1 with a certain pressure.
  • Two water jets 10 emerge from the nozzle head 8 and strike the inner walls 9 of the flue 2.
  • the hose drum 4 is held by a drum carrier 12 in the horizontal.
  • a first axis 11 which corresponds to the drum axis, the tube 5 is unrolled or rolled up, so that the vertical height of the nozzle head 8 in the flue 2 changes.
  • the device 1 hangs on an I-beam 13 which extends into the plane of drawing of FIG.
  • the device 1 may be displaced along the I-beam 13 to be positioned over a flue (not shown) which may be located adjacent the flue 1.
  • the device 1 can be used by simply moving along the I-beam 13 for the cleaning of several flues of a combustion plant.
  • rotation of the drum support 12 about the second axis 15 of the hose 5 hanging on the nozzle head 8 is also rotated within the flue 1 to the vertical with the result that the water jets 10 are rotated in the flue 2.
  • a first servo motor 16 is provided for rotating the hose drum 4 about the first axis 11, while a second servo motor 17 rotates the drum carrier 12 about the second axis 15.
  • the two servomotors 16, 17 are controlled by a control unit, not shown.
  • the servo motors are controlled so that the inner surfaces 9 of the flue 1 are cleaned according to an individual cleaning pattern. Certain areas can be left out, while other areas can be cleaned longer and more frequently.
  • the water supply includes a pressure control so that the pressure with which the water comes out of the nozzle head 8 can be adjusted.
  • the pressure can be a function of the vertical height and the angle of rotation of the nozzle head 8 in the flue 1.
  • FIG. 2 shows the hose 5, which is connected to the nozzle head 8 in a rotationally fixed manner at the hose end 7.
