Definitions

  • the invention relates to a heat exchanger with a cylindrical steel jacket and two hemispherical head pieces, with the hot medium in the longitudinal axis through the Heat exchanger flows and is cooled by a cooling medium, which laterally in the Heat exchanger is introduced and derived.
  • heat exchangers are used to recover heat or to specifically cool or heat a medium, which can be gaseous or liquid.
  • a shell-and-tube heat exchanger is used to cool hot cracked gases from partial oxidation. These cracked gases have to be cooled from 520 ° C to 350 ° C, while gaseous process feed mixture (or in other cases water vapor) has to be preheated from approx. 200 ° C to 420 ° C. These cracked gases have a high potential for " metal dusting", a process that leads to the destruction of the metallic materials if the metal temperatures on the cracked gas side become too high.
  • Metal dusting is understood to mean high-temperature corrosion, which usually takes place in strongly carburizing gas atmospheres and leads to the removal and thus destruction of the metallic material. Metal, metal oxide, carbon and metal carbides are typically found as removal products. If the heat exchanger described were carried out in a countercurrent apparatus, the heat exchanger tubes and the tube plates on the hot side would come into the temperature range of "metal dusting". The required preheating temperature cannot be achieved due to an overlap by means of a DC heat exchanger.
  • DE-A-3039787 describes a heat exchanger in which hot medium is on the side is introduced into the heat exchanger and after various deflection in the area of Cooling tubes at the head of the heat exchanger is pulled off again.
  • the cold medium is on Bottom of the heat exchanger inserted and flows through double-walled cooling tubes, being the cold medium is first passed through the inner tube to the end of the tube is then returned in the opposite direction of flow through the outer tube.
  • the hot medium is cooled in a countercurrent process. The one with this heat exchanger possible temperature compensation is not sufficient, so that several heat exchangers are required.
  • the invention is based on the object Heat exchanger to develop a high temperature balance between the media makes it possible to manufacture at the same time inexpensively and the thermal and chemical demands, as well as a high resistance against Has high temperature corrosion.
  • the object is achieved in that the heat exchanger consists of one cylindrical steel jacket and two hemispherical headers, with a first Distribution chamber by means of pipes for the flow of hot medium with a second one Distribution chamber is connected, the tubes being the inlet area of the cooling medium and penetrate an outer chamber, and that side nozzle the cooling medium in one Conduct inlet area, which is followed by an inner chamber through a sealing Plate for deflecting the flow of the cooling medium is limited to the sealing plate guides the cooling medium from the inner chamber into an outer chamber, the outer Chamber encloses the inner chamber, and this outer chamber with nozzle for Derivation of the cooling medium is provided.
  • the insulation of the dividing wall between the inner chamber and the outer chamber has the Effect that the cooling medium does not cool down on the hot side.
  • the pipes are welded to the bottom of the distribution chamber.
  • the Inlet area through a heat insulating mass thermally from the distribution chamber separated or isolated. Due to this heat-insulating mass, insertion tubes are inserted into the Bottom of the distribution chamber used to receive the cooling tubes.
  • Another embodiment of the invention provides that the heat insulating mass is catalytically active. This will cause leakage currents through cracks in the lining during the Continuous cooling is continuously converted catalytically, which means no “metal dusting "reaction can take place.
  • the inner parts of the heat exchanger are designed in a floating head construction. This means that the components that are exposed to high thermal expansion are only permanently stored on one side. The other side is freely movable in the longitudinal direction.
  • the outlet connector of the hot medium is equipped with a compensator.
  • the hot media introduced can be gases or liquids. You will be using a Temperature from 150 ° C to 550 ° C introduced into the heat exchanger and in one Temperature range from 400 ° C to 50 ° C dissipated.
  • the cooling medium usually exists from gases, vapors or liquids and is introduced at 30 ° C to 350 ° C. After Heat transfer heats the cooling medium up to 450 ° C.
  • Design options of the method are exemplary with the help of the drawing explained.
  • the heat exchanger (1) consists of a cylindrical steel jacket (13) with hemispherical head pieces (21, 15).
  • Hot medium (2) flows through an inlet connection (4) into a distribution chamber (5) and flows through a plurality of pipes (6), which are arranged parallel to the longitudinal axis of the heat exchanger (1), into a second distribution chamber (7) discharged there via the outlet connection (8).
  • Cooling medium (3) is introduced into the heat exchanger (1) through side connections (9).
  • the cooling medium (3) is introduced into an inlet area (10) to which the inner chamber (11) of the heat exchanger (1) is connected.
  • the inner chamber (11) is significantly smaller in diameter than the inlet area (10), since it is surrounded by an outer chamber (12), which is bounded on the outside by the steel jacket (13) of the heat exchanger, and on the inside by a wall (14) is separated from the inner chamber (11).
  • This wall (14) is made insulated.
  • the tubes (6) first penetrate the inlet region (10), then the outer chamber (12) and end in the second distribution chamber (7).
  • the cooling medium (3) flows through the inner chamber (11) and meets a sealing plate (16) which separates the cooling medium (3) from the medium (2) to be cooled in the distribution chamber (7).
  • the cooling medium (3) is deflected in this direction on this sealing plate (16) and in the process conducted into the outer chamber (12) of the heat exchanger (1).
  • sheets (17) deflect the cooling medium (3).
  • the cooling medium (3) flows around the pipes (6) of the hot medium in counterflow.
  • the cooling medium (3) is guided in its flow direction through sheets (17) in such a way that it flows alternately against the cylindrical steel jacket (13) and the separating wall (14) of the inner chamber (11).
  • the cooling medium leaves the heat exchanger (1) through the connector (18).
  • the sheets (17) ensure increased stability and guidance of the tubes (6).
  • the cooling medium (3) flows from the inlet area (10) to the inner chamber (11) in the same direction with the introduced hot medium (2) that flows through the pipes (6) in this area.
  • the cooling medium (3) flows against the direction of flow of the hot medium (2).
  • a compensator (19) is attached to the outlet connection (8).
  • the expansion of the steel jacket (13) can thus be compensated for.
  • the internal fittings are designed in a floating version.
  • the heat exchanger is made of heat-resistant steel. Depending on the media, a corrosion-resistant material can also be used.
  • the insulation of the wall (14) consists of ceramic or mineral fibers, which are surrounded by a protective jacket.
  • the hemispherical head pieces (21, 15) of the heat exchanger (1) are insulated with ramming compound.
