Definitions

  • the invention relates to a device for the selective feeding of cleaning bodies into the tubes of heat exchangers, in particular condensers, within the inlet chamber, with a device for feeding the cleaning bodies into a partial area of the tube sheet provided with the open tube ends, which extends from partial area to partial area is movable, with a collecting device for the cleaning bodies after leaving the Pipes and with a lockable connection including a pump between the feed device and the collecting device.
  • Such a device is known for example from DE-PS 28 18 033.
  • similar devices are also known on smaller type heat exchangers, in which the cleaning bodies flow through the exchanger tubes only in one direction.
  • sieves are then present, which push the cleaning bodies out of the outgoing medium and feed them to a removal opening within the pipeline.
  • the cleaning bodies are then added to the incoming medium again via a pump, a lock and, if appropriate, further units .
  • Both types of cleaning body circulation have in common that the distribution of the individual cleaning bodies on the pipes is left to chance, although a statistically ascertainable probability for the frequency of cleaning a specific pipe can be specified according to its position. Because of these conditions, heat exchanger tubes through which cleaning bodies flow and which flow through them less frequently generally occur. In the specific individual case, the frequency of the cleaning operation or the number of cleaning bodies is selected so that the pipes cleaned with the least frequency are just adequately cleaned without a recognizable drop in the efficiency of the heat exchanger.
  • a cleaning frequency of 1 to 6 cleanings per week is aimed at with an average of e.g. For example, three runs per week, 100 pipes per facility for feeding are 10% outside the specified limit values of one run or six runs. Attempts have already been made to achieve a more uniform distribution of the cleaning bodies on the individual pipes in that the supply is no longer carried out by a general feed into the water flow, but rather several inlet pipes for the cleaning bodies are arranged in the inlet chamber, each of which then only has one Provide part of the tube sheet with cleaning elements (Japanese utility model Sho 58-15898).
  • the invention proposes that the outlet opening of the feed device covers only a single pipe end in each section and can be moved to each pipe end of the inlet chamber.
  • the collecting device can either be carried out generally with the aid of a known sieve or a plurality of sieves or by a collecting device which is essentially identical to the feeding device and which is correspondingly tracked from pipe end to pipe end.
  • each cleaning body from the outlet opening into the pipe end in the entry chamber or from the pipe end into the trailing collecting device takes place virtually automatically if the outlet opening has approximately the same nominal diameter as the pipe and reaches a degree of coverage that is up to one error May be 1/4 d. Due to the water flowing into the pipe end, the cleaning body is automatically centered and taken along.
  • the tracking device that is tracked, it is for the same purpose It is advantageous if, with the help of a pump, a somewhat higher water entry speed into the collecting device is effected at the transition point than is predetermined by the natural flow through the heat exchanger. In this case, too, an automatic suction of a cleaning body emerging from the pipe end takes place, so that a precise alignment of the pipe end and the inlet opening of the collecting device can be dispensed with.
  • the feed device consists of a length-adjustable tube which is held in the inlet chamber wall with the aid of a bushing which can be moved almost everywhere.
  • the inlet chamber does not contain any reinforcements or the like which serve to reinforce it
  • the outlet opening of the tube can be directed to any point on the tube sheet and, due to the length adjustment, a sufficiently small distance can be established between the outlet opening and a tube end; the feedthrough is arranged in the region of the perpendicular to the tube sheet.
  • the end of the tube that extends beyond the bushing is used for alignment with the individual ends of the heat exchanger tubes and for adjusting the length.
  • spindles engage at corresponding points, which are preferably moved with the aid of stepper motors.
  • a storage can be carried out for each position of the feed device in front of a pipe end, which can be called up at any time and, for example, enables the step-by-step adjustment of the feed device from one pipe end to the other.
  • a further exemplary embodiment of the feed device can consist of a mouthpiece which can be moved directly above the tube plate in polar coordinates or Cartesian coordinates and which carries the outlet opening as well as one attached to the mouthpiece Hose which starts from a passage in the inlet chamber wall.
  • a rigid, length-displaceable tube can be used, which can be moved almost on all sides in the leadthrough, in which case, for example, one coordinate can be brought about by moving the tube, while the other coordinate can be achieved by means of an indirect displacement of the mouthpiece.
  • the number of cleaning bodies in circulation is expedient to select the number of cleaning bodies in circulation to be greater than the number that can be fed in per unit of time and with the aid of a metering device within the connection from the screen or from the collecting device to the inlet feeder just allocate the feedable number.
  • the measuring probes gain and the measuring probe on the feeding device gains particular importance.
  • the egg can be supplied by hydraulic means, that is to say with wet cleaning bodies. Deviating from this, each cleaning body can be removed from the carrier medium, separated, metered and fed back into the partial stream of the carrier medium which is fed via the feed device.

Abstract

Dispositif pour introduire sélectivement des éléments nettoyants (6) dans les tubes (5) d'échangeurs de chaleur (1). Les régions partielles de la plaque tubulaire (4), dans laquelle les éléments sont introduits, sont sélectionnées de manière à être si petits qu'un seul tube (5) à la fois peut être traité par les éléments nettoyants (6). On exclut ainsi les accidents statistiques, de sorte que les tubes (5) fragiles, par exemple ceux réalisés en alliage de cuivre, sont nettoyés ni trop souvent ni trop rarement, et qu'en conséquence on obtient un bon rendement pour une faible corrosion.
