Definitions

  • a plate heat exchanger which consists of plates and separating sheets made from polytetrafluoroethylene, the plates being provided with channels on one or both sides. The channels of adjacent plates are separated by sheets made from polytetrailuoroethylene.
  • the present invention relates to a plate heat exchanger from polytetrafluoroethylene.
  • plate heat exchangers To carry out the heat exchange, which is necessary in industry in a great number of different chemical processes, various types of apparatuses have been proposed, inter alia so-called plate heat exchangers.
  • the known plate heat exchangers are made, in the first place, of corrosion resistant metallic materials of high quality.
  • the present invention provides a plate heat exchanger which consists of plates and separating sheets from polytetrafluoroethylene or materials containing polytetrafluoroethylene, the plates being provided with ribs and channels in such a manner that the heat exchange of two mediums led in the channels formed by the ribs takes place through the separating sheets and the plates.
  • FIG. 1 is a top view of a plate of a heat exchanger and three sectional views along lines a-a, b-b and c--c,
  • FIG. 2 is a top view of a plate of another heat exchanger and three sectional views along lines dd, ee and f
  • FIG. 3 is a top view of the tube connection and
  • FIG. 4 is a cross sectional view of the tube connection.
  • the individual elements of the heat exchanger can be connected in series as can be seen by section bb of FIG. 1 or in parallel as can be seen by section e-e of FIG. 2.
  • the packs of plates and sheets is held together by means of two terminal plates of steel 4 and the corresponding tie rods 5.
  • two sparings 6, 7 are provided for the connection sockets 9/10 for the inlet and outlet of the exothermic and endothermic mediums.
  • the sectional views show that the ribs must be exactly one on top of the other so that the separating sheet may resist, it necessary, as high as possible a differential pressure of the two mediums.
  • the novel plate heat exchanger may easily be adapted to the most various conditions of quantity and operation, for example, the heat exchange of liquid mediums, the condensation of vapours, or vaporization processes.
  • connection sockets 9/10 are pressed by means of divided rings 11/12 shifted by against polytetrafiuoroethylene plates 8, which are provided with distribution channels.
  • the plate heat exchangers in accordance with the invention may be manufactured-depending on the chemical or thermal stressfrom different materials or material combinations.
  • the plates of the heat exchanger may be manufactured completely or partially from other materials, for example ceramics, in which case the separating sheets 3 may also consist of metals or carbon.
  • a plate heat exchanger comprising outer and central grooved plates of polytetrafluoroethylene, sheets of polytetrafluoroethylene, said outer plate having grooved channels in one surface, said central plate having grooved channels in both of its surfaces, said plates and said sheets being disposed in a pack with at least one central plate disposed between grooved surfaces of a pair of said outer plates and said sheets being disposed inbetween said plates, said grooved channels in said plates being algined and separated from each other by said sheets, terminal plates on the outer sides of said outer plates, tie means holding said assembled plate and sheets together, connecting conduit means on said terminal plates for supplying and discharging fluid from said plate heat exchanger, connecting passage means in said outer and central grooved plates for causing said fluid to flow into and out of said grooved channels, and said connecting conduit and passage means being constructed and arranged to cause the fluids between which heat is exchanged to separately flow in said grooved channels on opposite sides of said sheets whereby heat is exchanged through said sheets between said fluids.
