Definitions

  • the invention relates to a device for cleaning the heat-exchanging surfaces of the storage masses of regenerative heat exchangers with rotatingly driven hoods by means of a cleaning fluid which emerges from at least one nozzle essentially parallel to the planes of the heat-exchanging surfaces, the nozzle being movable relative to the storage mass.
  • Cleaning devices for the storage masses of regenerative heat exchangers are known both for rotating storage masses and fixed guide devices as well as for fixed storage masses and rotating hoods.
  • Compressed air or superheated steam is preferably used as the cleaning agent, but sometimes also water, to which anti-corrosion inhibitors and wetting agents or solvents can be added.
  • the invention has for its object to provide a cleaning device of the type described, which in addition to a simple construction and high reliability has a low weight and a small space requirement, so that they have no disruptive influence on the flow conditions within the regenerative heat exchanger Consequence.
  • the solution to this problem by the invention is characterized in that the nozzle is arranged at the end of an at least two-part, telescopic nozzle tube which is fastened to the hood of the regenerative heat exchanger and is connected by a feed line to a transfer device arranged in the center of rotation of the hood and which comprises a tube piece rotating with the hood and a includes a stationary, sealed from the pipe section.
  • a particularly light, space-saving and simple cleaning device which essentially consists only of the telescopic nozzle tube and a transfer device through which the cleaning fluid is supplied to the nozzle tube arranged on the rotating hood.
  • the nozzle tube provided with at least one nozzle is adjusted in the radial direction relative to the storage mass, so that all the heat-exchanging surfaces of the storage mass are cleaned in succession by the rotating movement of the hood.
  • the main part of the telescopic nozzle tube lies in the area of the hood that covers the storage mass, so that only the extendable end of the nozzle tube protrudes into the actual flow cross section.
  • the flow area of this extendable part of the nozzle tube is so small, however, that no disturbances in the flow occur. Due to the displaceable arrangement of the nozzle, the device according to the invention can be used for targeted cleaning, so that the advantage is further achieved that the throughput quantities of the cleaning fluid can be reduced compared to known designs.
  • the nozzle tube is formed in two parts from a base part arranged on the hood and a displacement part which can be displaced relative to the base part, the rear end of the base part on the outer circumference and the front end in the region of the rotating means point of the hood is arranged.
  • a displacement part which can be displaced relative to the base part, the rear end of the base part on the outer circumference and the front end in the region of the rotating means point of the hood is arranged.
  • the moving part is connected to an endless, flexible tension element, which is guided via two deflection rollers and whose one deflection roller is connected to a drive wheel which is driven step by step by at least one stationary stop during the rotary movement of the hood.
  • FIG. 1 The schematic plan view of a regenerative heat exchanger according to FIG. 1 shows a fixed storage mass 1, which is equipped with heat-exchanging surfaces in the direction of view, through which hot flue gases and fresh air to be warmed up alternately flow.
  • the change of these two flow media is achieved by a rotating hood 2.
  • Such a hood 2 is arranged on each of the two end faces of the cylindrical storage mass 1.
  • the direction of rotation of the hood 2 is indicated in Fig. 1 by arrows.
  • a cleaning device is arranged on the hood 2 and thus rotates together with the hood 2.
  • 1 shows a housing 3 of this cleaning device and the front end of a telescopic nozzle tube 4, in which at least one nozzle is formed.
  • a cleaning fluid emerges from this nozzle essentially parallel to the planes of the heat-exchanging surfaces of the storage mass 1.
  • An embodiment of this cleaning device is shown in Fig. 2.
  • the nozzle tube 4 is designed in two parts and can be telescoped. It consists of a base part 4a fastened to the hood 2 and of a moving part 4b which has nozzle openings 4c at its front end.
  • the tubular travel part 4b which is closed at the front end except for the nozzle openings 4c, can be displaced in the longitudinal direction on the base part 4a, as indicated by the double arrow and the dash-dotted lines in FIG.
  • Seals 4d are arranged between base part 4a and travel part 4b, which are in any position of the travel part 4b relative to the base Part 4a prevent cleaning fluid from escaping between base part 4a and travel part 4b.
  • the cleaning fluid is fed to the nozzle tube 4 through a feed line 5, which is connected to a stationary line 7 by means of a transfer line 6.
  • a housing 6a is arranged at the end of this line 7 coming from a pressure source for the cleaning fluid.
  • This housing 6a is located in the center of rotation of the hood 2 and is aligned concentrically with the axis of rotation of the hood 2.
  • the open end of a pipe section 6b which is provided with a sealing ring 6c located in the housing 6a, projects into this fixed housing 6a.
  • This pipe section 6b with sealing ring 6c rotates with the hood 2 and is - as can be seen in FIG. 2 - connected to the feed line 5.
  • the moving part 4b is designed to be displaceable on the base part 4a.
  • 3 and 4 show an exemplary embodiment of the adjustment device required for this.
  • two deflection rollers 8a and 8b are rotatably mounted in the housing 3, over which an endless flexible tension element, for example a rope 9, runs.
  • a driver 9a is attached to this rope 9.
  • the cable 9 is driven with the aid of a drive wheel 10, which is connected in a rotationally fixed manner to the deflection roller 8a via its shaft 10a.
  • Fig.l the drive wheel 10 is shown in dashed lines. It can be seen from this illustration that the drive wheel 10 protrudes slightly from the circumference of the hood 2. In this way, the drive wheel 10 provided with projections 10b can be rotated by means of stationary stops 11 when the hood 2 rotates past these stationary stops 11 with the drive wheel 10.
  • Stops 11 can be used to control the gradual rotation of the drive wheel 10, it being possible, according to the double arrows drawn in FIG.
  • the circulating movement of the cable 9 generated with the aid of the drive wheel 10 is used to adjust the moving part 4b relative to the base part 4a.
  • driving pins 4e are arranged on the moving part 4b.
  • Fig. 4 it is shown that when the driver 9a rotates, first the moving part 4b is moved radially outwards from the collapsed position of the telescopic nozzle tube 4, in which the nozzle openings 4c cover the radially innermost part of the storage mass 1 End position of the feed movement has been reached. Subsequently, the driver 9a starts the return after its rotation around the deflection roller 8b.
  • the moving part 4b is carried along via the second driving bolt 4e in the direction of the end position of the return movement.
  • the driving bolts 4e are slightly offset from one another in the longitudinal direction of the moving part 4b, as shown in particular in FIG.
