Definitions

  • the invention relates to a self-cleaning heat exchanger.
  • Heat exchangers are used to utilize residual energy in many areas of technology and, in the present configuration, are essential for the concentration of acids, lyes, saline solutions, electrolytes, alcohols, digestate and other suitable liquids.
  • liquid media which interact with other media to influence technological / process engineering processes and / or are exposed to reactions lose their initial concentration. They are then no longer suitable for a continuous circulation, which is to provide a corresponding final result in a procedure. For this purpose, these liquid media must either be replaced or prepared for reprocessing by reprocessing, which is a known concentration.
  • the concentration usually takes place by means of heat exchangers.
  • the z. B. cylindrical heat exchanger can take a lying or a standing, the latter connected to a socket, position.
  • the flow rate of the liquid medium to be concentrated deteriorates during operation of the heat exchanger by settling on its wall in the interior, on the tubes and / or at its bottom solids, whereby the heat transfer from the tubes of the heat exchanger to the flowing liquid medium, the concentrated should be uneconomical with time decreases.
  • downtime of such systems must be scheduled at regular intervals, so that a basic cleaning of the heat exchanger can be made and possibly existing in him pipes can be replaced.
  • the self-cleaning heat exchanger has a novel design of a plastic or multiple webs made of metal and the inner diameter of the heat exchanger adapted pressure plate which is arranged to be movable continuously movable on the inner wall of the heat exchanger and along the / of the tube bundle / -s.
  • the pressure plate has a defined thickness and an additional larger recess adjacent to the openings for the tubes of one or more tube bundle / -el.
  • the openings for the tubes in the thrust washer also have cylindrical bearings with a defined clearance, so that tilting of the thrust washer, which can also consist of several webs, is practically impossible.
  • a plurality of thrust washers may be present in a heat exchanger several times in succession over several sections thereof, all of these thrust washers are moved synchronously from the outside via a centrally located push rod or spindle.
  • a hydraulic or pneumatic stamp initiates the vg movement.
  • the construction of a thrust washer is provided in such a way that, owing to a plurality of webs and thus a larger bearing sliding surface, a tilting of these thrust washers does not take place.
  • the Lagergleit vom are formed by a game provided sleeves - in particular made of plastic - which are located in the openings for the tubes in the pressure plates formed.
  • the self-cleaning heat exchanger 1 consists of a jacket tube 1 a, one or more tube bundles / n 2, 5, tube plates 10 and from it on both sides closing dished ends (not further positioned) and the inventive device for continuous cleaning, which is located in its interior and to be described in more detail below.
  • FIG. 1 is in the central position of the self-cleaning heat exchanger 1 to recognize a spindle 6, which is mounted or guided in the tube sheets 10. It is offset from the outside by means of a geared motor 20 in motion, wherein a pressure plate 4, 7, 9 - shown here in 3 essential positions - is carried along and thereby along the peripheries of all tubes of the tube bundle 2, 5 slides. This sliding movement is constantly in a forward and backward movement up to the corresponding reversing positions, which is realized by a corresponding control of the geared motor 20. To minimize the expenditure of force in overcoming the internal pressure of the medium during the aforementioned movements, the webs 11 of the pressure disk 4, 7, 9 contain openings 8 through which the medium to be concentrated can pass.
  • the webs 11 are fixed by spacers 12 in their position.
  • the webs 11 further have a plurality of tube openings 13, in which plastic sleeves 14 are integrated, which are in direct sliding contact with the tubes of the tube bundle 2, 5.
  • the Kunststoffülsen 14 are defined angularly movably mounted, so that tilting of the known from 2 or more webs 11 thrust washer 4, 7, 9 is avoided during their translations and the occurrence of thermal stresses in the metallic materials.
  • FIG. 2 It can be seen that the self-cleaning heat exchanger 1 is installed vertically in a Aufstellgerüst 17. With FIG. 3 an open, without jacket tube 1a with a plastic pressure washer 18 equipped self-cleaning heat exchanger 1 is shown.
  • the plastic pressure plate 18 has a defined thickness, which prevents tilting and at least one opening 19 to minimize the media jam. You, the plastic pressure plate 18, fulfills the same function as a pressure plate 4, 7, 9, which consists of successively arranged webs 11.
