Definitions

  • the invention relates to a heat exchanger with a Connector between an uncooled pipe and several cooled pipes according to the preamble of claim 1.
  • Connectors for heat exchangers are known (DE-PS 39 10 630) where the end of a hot, uncooled pipe is forked outward and thermally insulated. This Connector directs the hot gas into a single one outside z. B. tube cooled by boiling water. This Principle has proven itself. However, in some ways it is considered disadvantageous to consider that the cooled pipe, which in the Diameter corresponds approximately to the uncooled pipe, due to its large diameter must be made relatively long. This is due to thermodynamic reasons Desired cooling of the hot gas to a certain one To reach temperature.
  • the length of the cooled pipe can be considerably shorter and therefore the heat exchanger can be run more cost-effectively if that hot medium from an uncooled pipe to a plurality of cooled pipes of smaller diameter is distributed.
  • Constructions are known in which a hot medium from an entry to a plurality by means of an entry chamber of chilled pipes that are distributed in a common Tube sheet are held.
  • this is disadvantageous Turbulence of the flowing medium when it hits the Tube sheet and possible tube sheet erosion.
  • Double-tube heat exchanger In another known double tube heat exchanger, a Connection piece used, the manner of a downpipe is formed and while maintaining the cross section branched into two or three branch pipes. Any of these Branch pipes are assigned to one of the double pipes.
  • This Double-tube heat exchangers have basically the same Disadvantages such as the double tube heat exchanger according to US-PS 54 64 057.
  • the invention has for its object the generic To design heat exchangers so that a hot medium of an uncooled pipe using a connector relatively simple and inexpensive design with low turbulence a plurality of cooled pipes can be distributed at at the same time compact, space-saving design under Avoiding a tube sheet with direct flow.
  • the guide channels Due to the arrangement of the guide channels and of the corresponding cooled pipes on the smallest possible enclosable area, it is possible for the guide channels a common preferably cylindrical shell to provide. The same applies to the cooled pipes, which thereby also performed in a common outer jacket can be. This enables an inexpensive and space-saving cylindrical design of the heat exchanger.
  • the heat exchanger 1 shown only partially serves for Cooling a hot gas with the help of a cooling medium preferably boiling water.
  • the hot gas is preferably cracked gas produced in a cracking furnace was and in a short time to a lower temperature must be cooled. This hot gas emerges from the cracking furnace through one or more uncooled pipes 2.
  • Each uncooled pipe 2 is via a connector 3 with the Heat exchanger 1 connected.
  • the heat exchanger 1 consists of several z. B. four chilled Pipes 4, whose inner diameter is less than that Inside diameter of the uncooled pipe.
  • the cooled pipes 4 are arranged on a pitch circle and from one cylindrical outer shell 5 surrounded.
  • the cooled pipes 4 are welded into a tube sheet 6.
  • To the tube sheet 6 closes in the longitudinal direction of the tubes 4 Entry chamber 7 for the supply of a coolant.
  • the outer wall of the inlet chamber 7 is open in the axial direction on one side with the tube sheet 6 and on the other side welded to the outer jacket 5.
  • the end of the heat exchanger 1 shown are the cooled tubes 4 held in a second tube sheet and by one Outlet chamber for the cooling medium surrounded.
  • the connector 3 consists of a cylindrical Input section 8, the inside diameter of which the uncooled pipe corresponds. This input section 8 is e.g. B. by welding to the uncooled pipe 2 connected. The input section 8 of the connector 3 extends to a cylindrical end section 9.
  • the input section 8 of the connector 3 is Star-shaped branches into several guide channels 10, of which each is assigned to one of the cooled tubes 4.
  • the End section 9 of the connecting piece 3 encloses this Guide channels 10.
  • the guide channels 10 are coaxial to the cooled tubes 4 arranged and on the same pitch circle aligned like this.
  • the inside diameter of the chilled Pipes 4 is equal to or larger than the inside diameter of the guide channels 10.
  • This end section 9 is on the cooled pipes 4th load-bearing tube sheet 6 welded. Between each other facing end faces of the guide channels 10 and cooled tubes 4, a gap remains, the one Allows thermal expansion.
  • the space between the guide channels and the end section 9 of the connector 3 is with a heat insulating Material filled out.
  • the connector 3 can consist of one metallic, heat-resistant material inexpensive and cast in one piece or manufactured as a welded construction his.
  • the connector 3 described conducts the hot gas the cooled tubes 4 with little turbulence. By voting the inner diameter and the contour of the guide channels 10 and the cooled tubes 4 on top of each other is a swirling of the Gas excluded, and erosion of the tube sheet 6 can do not occur.
