Definitions

  • the invention relates to a cleaning device for heat exchanger trains of, especially burner-heated boilers with at least one cleaning element and with a holder for the cleaning element.
  • a cleaning device for heat exchanger trains of burner heated Kesseln is known from AT 399 385 B.
  • Boilers described are in the heat exchanger cables in the essential, but rotatable and in the axial direction oscillating cleaning elements provided over a common drive can be rotated.
  • the disadvantage of such a cleaning device is in that the cleaning elements permanently in the tubes of the Heat exchanger are arranged, making the pipe cross section is also reduced during the boiler operation and on the cleaning elements contained in the exhaust gas can deposit.
  • the invention is therefore based on the object, a generic Specify cleaning facility that the mentioned Avoids disadvantages as possible.
  • At least one cleaning element is provided, that can be inserted into the heat exchange cables.
  • the Cleaning device according to the invention can thus be preferred be used during a boiler break.
  • there is only one Cleaning element is provided, one after the other in the flue gas can be pushed in and via an adjustment mechanism is movable transversely to the longitudinal direction of the flue gas flues.
  • the adjustment mechanism is a guide for the cleaning element, which in axial Direction can be positioned in front of the heat exchanger cables.
  • the course of the cleaning process is preferred by one electronic program control that controls the leadership via the adjustment mechanism one after the other in front of the individual heat exchanger cables positioned, after which the cleaning element easily into the individual heat exchanger cables one or more times pushed in and pulled out again can to clean them.
  • Another embodiment of the invention is characterized in that that several cleaning elements are provided, the at a distance corresponding to the distance between the flue gas flues arranged from each other and parallel to each other in the flue gas flues can be introduced. In this embodiment, it can Cleaning the flue gas flues carried out much faster be cleaned since several or all flue gas flues at once can be.
  • This bracket can, for. B. from a pressure cylinder or a rack and pinion gear be driven.
  • the Flue gas duct of the heat exchanger closed by a cover is, and that openings are arranged in the cover through which the cleaning elements can be inserted into the flue gas flues and preferably that the openings in the lid by a closure device are lockable.
  • FIG. 1 shows a vertical section through one with a Boiler equipped cleaning device according to the invention
  • FIG. 2 the cleaning device of FIG. 1 in more detail
  • Fig. 3 shows an axial section through part of a heat exchanger a boiler with a second embodiment of a cleaning device according to the invention
  • Fig. 4 is a view to the arrangement of Fig. 3 from the left with the proviso that the housing of the cleaning device for the sake of a clearer representation has been omitted.
  • Fig. 1 denotes a combustion chamber of a boiler, the 7 heating material supplied from below via a feed screw becomes.
  • the from the combustion chamber 1 through an outlet opening 12 escaping flue gases are through a heat exchanger 3 passed through.
  • the combustion chamber 1 becomes secondary air via a blower 6 and a secondary air line 10, the opens into the combustion chamber 1 in the area of the outlet opening, fed.
  • a primary air supply line is designated.
  • a screw conveyor 5 is provided for Ash removal from the combustion chamber 1 into an ash container 14 .
  • combustion chamber 1 In the combustion chamber 1 is above the outlet for Fuel a control flag 8 arranged to the optimal Monitor fuel level.
  • the ceiling 11 of the combustion chamber 1 is curved and lined with fireclay parts.
  • the boiler 13 is up through a boiler cover 17 completed.
  • a dust extraction chamber 4 In the flow direction after the heat exchanger 3 is a dust extraction chamber 4, in which a tube 12 opens for the extraction of the flue gases.
  • a closing organ for the combustion chamber 1 is actuated by a pressure medium cylinder 16 operated.
  • flue gas flues 36 are provided, as in Fig. 2 can be seen.
  • cleaning elements 21 on support rods 24, which are at a distance from each other a bracket 20 are attached, the distance between the flue gas 36 corresponds.
  • the cleaning elements 21 are as Sweeping brushes trained and can in the flue gas 36 and be pushed out.
  • pressure cylinders are 18 provided on the one hand on the bracket 20 and on the other hand on a housing 2 of the cleaning device attached.
  • drive devices for the holder 20 can also be any other facilities, e.g. Rack and pinion gear, be used.
  • the heat exchanger 3 is closed by a cover 29, in which there are openings 30 through which the cleaning elements 21 can be performed.
  • the openings 30 are pivotable by means of locking devices 23 Flaps mounted on the lid 29 completed when the Cleaning elements 21 in the withdrawn shown in Fig. 2 Position, which makes it possible to use the cleaning elements 21 when the boiler is operating outside the heat exchanger 3 to be protected from heat.
  • To operate the Flaps 23 are these via push rods 26 with a cross bar 27 connected.
  • the cross bar 27 is in turn over rods 22 connected to the bracket 20. Project through the rods 22 both the bracket 20 and the bar 27 and are over Heads 28 secured against sliding out of them.
  • the holder 20 is located in that shown in FIG. 2 Position, then the flaps 23 over the rods 24, the Strip 27 and the push rods 26 folded up so that the openings 30 are closed. If the bracket 20 lowered, then the bar 27 can slide down so far, that the flaps 23 on the push rods 26 completely after be folded down so that the openings 30 for pushing through the brushes 21 are released. Because the rods 22 sliding included in the bracket 20 and in the bar 27 are, the bracket can then continue unhindered move downwards so that the brushes 21 and the flues 36 can clean.
  • the heat exchanger 115 of a boiler has a number of Flue gas flues 106.
  • a single cleaning element 105 in the form of an elongated Brush provided in its out of the flue gas 106 retracted position in a substantially cylindrical Guide or brush chamber 104 added is.
  • the guide 104 To move the brush 105 transversely to the longitudinal extent of the Flue gas flue 106 is the guide 104 with the piston 119 one Pressure cylinder 101 connected.
  • the cylinder 120 of the Pressure cylinder 101 is in turn via a pivot bearing 116 pivotable on a housing 108 of the cleaning device stored.
  • Another pressure medium cylinder 118 is provided, the one hand on the cylinder 120 at a distance from the pivot bearing 116 Bearing 121 and with its cylinder end via a bearing 122 is hinged to a housing-fixed bracket 123.
  • the pressure medium cylinders 101 and 118 By operating the pressure medium cylinders 101 and 118 can the cleaning element 105 in the guide 104 before each flue 106 can be positioned, which is preferred program or computer controlled.
  • the pressure medium cylinders 101 and 118 are measuring elements 102 and 124 provided, which is the current position of the respective Piston rods record which data are available to the control system be put.
  • the cleaning element 105 is in the guide 104 in solid lines in a so-called waiting position shown in an area 128 within the housing 108, in which this is not arranged in front of any flue gas duct 116 are.
  • the advantage of this waiting position is that on the one hand the flow of the exhaust gases from the flue gas flues 106 and is not obstructed in the flue gas flues 106 and on the other hand, the heat load on the brush 105 was kept low while the boiler is in operation.
  • the drive of the cleaning element 105 in the axial direction takes the form of a Bowden cable, i.e. that it is flexible Drive element 110 guided in a tubular sleeve 111 is.
  • One end of the sheath 111 is from the heat exchanger 115 opposite end 126 of the guide 104 attached and performs an inlet opening 127 in a closure plate 113, the opposite the heat exchanger 115 on the housing 108 by means of Screws 114 is screwed on.
  • the brush 105 is moved by means of the Bowden cable 110, 111 in the axial direction by one in the drawings Linear motor, not shown, which the drive element respectively drives the flexible shaft 110.
  • the flexible shaft 110 may also be in Direction of rotation are driven to the brush 105 in addition to give a rotational movement to their axial movement.
