Definitions

  • the present invention relates to a heat with a set of tubes and tube plates and more particularly a heat exchanger suited for the treatment of highly corrosive fluids or the ones for which a high level of purity must be ensured.
  • Heat exchanger are known for processing highly corrosive fluids or fluids with special purity requirements, wherein the tube plates are of a suitable material, such as solid PTFE.
  • the tubes are sealed with the plate by means of threaded ring nuts, directly tightened in a threading provided in the PTFE.
  • This solution presents drawbacks connected with the not satisfactory mechanical resistance of the plates, especially at high temperatures, which limits the possible applications of the exchanger and renders frequent maintenance necessary.
  • a possible alternative is the use of PTFE coated steel plates; the coating is necessarily thin, which renders it not always sufficiently impermeable, and unsuitable for providing a proper sealing for the tubes passing through the plate.
  • a heat exchanger comprising a set of tubes consisting of SiC tubes mounted between two tube plates in enamelled steel by means of a pressure seal system on the outer surface of each tube, in which the tube can axially slide therein to compensate for thermal expansions.
  • Fig.1 is briefly represented a heat exchanger according to the present invention, comprising a set of tubes in silicon carbide (SiC) (11) and tube plates in enamelled steel (12) as the essential members.
  • SiC silicon carbide
  • both the central shell (14) and the end distributors (13) may be provided in enamelled steel.
  • a characteristic and original aspect of the heat exchanger according to the invention is represented by the enamelled tube plates substituting the traditional ones in PTFE (PolyTetraFluoroEthylene) see Fig. 2 reference 21 or the ones in PFTE-coated steel (see Fig.3 reference31).
  • PTFE PolyTetraFluoroEthylene
  • the tube plate may deform over time and bend under pressure, subjecting the ends of the SiC tubes (particularly the most exterior ones with respect to the set of tubes) to flexing stress beyond their ultimate stress. For this reason in practice they do not exceed ⁇ 300 mm.
  • Fig.4 shows the embodiment of the exchanger with a single tube plate (41), with enamelling on the shell side, in which the O ring seal gaskets (42) are locked by the threaded ring nut (43) by means of the intermediate bushing (44).
  • the seal on the inner (by O ring reference 51 ) and the outer (by O ring reference 52) tube plate can be simultaneously achieved by a single locking of the threaded ring nut (53) by means of the intermediate bushing (54) in steel or in PEEK (phenylpolyetherketones of Du Pont), which is fitted with holes (55) for conveying possible fluid leakages to the outside.
  • the two seals on the tube are separate.
  • the seal is implemented by means of a double O ring gasket (62) pressed by an intermediate bushing in steel or in PEEK (64) by the screwing of a steel ring nut (63) in the corresponding thread provided in the tube plate.
  • the required pressure for pressing the O ring seals has been provided by means of a special bushing in glass-filled PEEK or PTFE (66), being pressed by the tube plate.
  • This pressure is applied during the coupling step of the two single plates by the locking of the screws located on an outer peripheral circumference of the enamelled area to avoid any point of discontinuity in the coating (see fig.7 reference 74).
  • the type of seal is characterised by a high degree of elasticity in the axial direction made by means of a mechanical spring system or an adequate number of overlapping O ring gaskets (68), in addition to those provided for pressure seal.
  • An underlying L-profile ring (69) ensures support to this elastic system regardless of the position of the underlying seal ring nut on the inner plate.
