Definitions

  • the invention relates to a heat exchanger, in particular for cooling cracked gas, with the features of the preamble of claim 1.
  • the gas flow supplied through the inlet nozzle spreads out in accordance with the expansion of the chamber cross-section.
  • the flow is uneven in such a way that the edge zones are flowed through less than the core zone.
  • the invention has for its object to provide a generic heat exchanger with such internals that both equalize the flow through the inlet end chamber and protect the tube plate from erosion.
  • the carbon particles carried by the gas flowing at high speed in the area of the core flow meet the rods of the insert, as a result of which their kinetic energy is destroyed.
  • the particles braked in this way are carried along by the gas and can no longer lead to erosion damage to the tube plate and the tubes.
  • the incident gas flow is partially directed radially outwards by the insert.
  • a partial flow can flow in the required amount between the ring distances to the pipes in the central area of the pipe plate.
  • Appropriate arrangement and dimensioning of the rods enables gas to be applied to all tubes of the tube bundle in a very uniform manner. The deflection of the gas flow to the outside is favored if the rods formed into rings form a cone.
  • the heat exchanger consists of a tube bundle of straight tubes 1, which are held in two tube plates 2 on both sides of the tube bundle.
  • the tube bundle is enclosed by an outer jacket 3 which, together with the tube plates 2, delimits an interior space through which boiling and high-pressure water flows.
  • the tube plate 2 is followed by an end chamber 4 on the gas inlet side and on the gas outlet side (not shown), which is provided with a nozzle 5 for supplying or discharging the gas.
  • the diameter of the nozzle 5 is significantly smaller than the diameter of the tube plate 2 , so that the end chamber 4 widens conically.
  • an insert 6 is arranged, which serves as a distribution element and as an impact protection.
  • the insert 6 is limited to that part of the tube plate 2 which is located in the area of the core flow of the gas supplied through the nozzle 5 and which is therefore most at risk from erosion.
  • the insert 6 consists of profile or round bars which are shaped into polygonal or round rings 7.
  • the insert 6 can be flat, the rings being concentric and arranged in one plane. It is advantageous to arrange the rings 7 - as shown - on a cone, the tip of which points to the socket 5.
  • the rings 7 are arranged at axial distances from one another.
  • the outside diameter of a ring 7 corresponds approximately to the inside diameter of the ring 7 following in the direction of the tube plate 2.
  • the diameter of the ring 7 adjacent to the tube plate 2 is somewhat larger than the diameter of the nozzle 5. This means that the projection area of the nozzle 5 on the tube plate 2 completely covered.
  • the rings 7 are connected to intersecting webs 8 which are fastened to the wall of the end chamber 4.
  • part of the inflowing gas is deflected into the edge zone, while another part of the gas passes between the rings 7 of the insert 6.
  • the diameter of the rods 7 formed to the rings and the mutual distance can be chosen so large that the distribution of the gas over the cross section of the tube plate 2 is uniform.
  • the arrows 10 in the left part of FIG. 1 show, the carbon particles carried along by the gas and flowing in a straight line meet the rings 7 and are braked.
  • the staggered arrangement of the rings 7 ensures that the carbon particles cannot hit the tube plate 2 at high speed.
