Definitions

  • the invention relates to a plate heat exchanger for media carried in cocurrent or countercurrent.
  • Such plate heat exchangers are known, they consist of shaped single plates which are connected to one another to form a flow channel for the plate pairs forming a medium, which in turn are joined to form a plate stack and each form a flow channel for the other medium.
  • the inflow and outflow cross-sections of each flow channel are offset diagonally to one another in the main flow direction.
  • the inflow and outflow cross sections of the channels for the two media lie next to one another, but are offset from one another by half the height of the inflow and outflow cross sections of the channels.
  • the invention has for its object to develop a plate heat exchanger of the type described above in such a way that with complete separation of the media participating in the heat exchange and with low pressure loss guidance of the media, a space-saving and compact design results, which furthermore the use of similar modules for individual adaptation of the heat exchange surfaces and the materials to the respective operating conditions and, in addition to good accessibility for maintenance purposes, creates an easy exchange option for the modules for repair purposes.
  • the solution to this problem by the invention is characterized in that a plurality of similar plate stacks are arranged directly next to one another, that the inflow and outflow cross sections of each plate stack are separated from one another by a central wall extending over the entire stack length, and that the central walls of adjacent plate stacks are each covered by a ceiling wall are connected to a common collecting duct and that these collecting ducts are connected alternately and with inclusion of the inflow or outflow cross sections of the two end-side plate stacks with a common inflow or outflow connection piece for each of the two media.
  • each plate stack consists of shaped individual plates, which are connected to each other to form pairs of plates, which in turn are assembled to form a plate stack
  • the heat exchanger according to the invention can be adapted to the operating conditions in a simple and inexpensive manner by using appropriate materials or coating the individual plates, so that the The plate heat exchanger of the invention is also used, for example, for aggressive media or media loaded with solid particles can be. Since the one medium is guided in the flow channels, which are formed by the formation of plate pairs, and the channels for the other medium are formed by the connection of the plate pairs to a plate stack, there is a slip-free separation of the media participating in the heat exchange, which in particular results in pollutant emissions leakages or solid matter transfer.
  • the plate heat exchanger according to the invention Since the media guided in cocurrent or in countercurrent to one another are fed without deflection to the plate stacks arranged next to one another, the plate heat exchanger according to the invention operates with low pressure losses and with relatively low gas velocities and without drives and moving parts, so that no additional noise emissions are generated. Even when installing a cleaning system that may be required, normal sound insulation without a complex housing for the plate heat exchanger is sufficient.
  • modules of the same type and a maximum of two different individual plates enables inexpensive production and simple assembly; in addition, it facilitates the adaptation of the heat exchange surface to the respective operating conditions, because the plate heat exchanger according to the invention can be varied particularly simply with regard to its heat exchange performance by changing the number of individual plates joined to form a plate stack and on the other hand by changing the number of plate stacks arranged side by side.
  • the collecting duct results in favorable inflow and outflow conditions of the media participating in the heat exchange to the heat exchange surface formed by the plate stack. Since the middle and ceiling walls connected to common collecting channels can be removed without problems, there is good access to the plate stacks for maintenance and repair purposes, with repair being facilitated in that complete modules can be exchanged. In addition to loss-free flow control and good accessibility, the collecting channels formed by central and ceiling walls also provide the possibility of installing any cleaning device that may be required.
  • This also has the advantage that the cleaning process can run in the direction of flow and that there is the possibility of guiding the cleaning agent, for example air, superheated steam or water, vertically from above through the stack of plates, so that no problems arise when collecting the cleaning medium contaminated with residues .
  • the cleaning agent for example air, superheated steam or water
  • the plate heat exchanger designed according to the invention leaves several options for the supply and removal of those participating in the heat exchange Media too.
  • the inlet connection and the outlet connection for each medium can either be arranged at the same end of the adjacent stack of plates or at the other end of the adjacent stack of plates. The supply and removal of each medium can thus either take place on the same side of the plate heat exchanger or lead to a crossing of the media within the plate heat exchanger, regardless of whether the two media are in cocurrent or countercurrent to each other and whether the supply is from below or above.
  • the invention proposes to design the ceiling walls of the collecting ducts to run obliquely.
  • FIG. 1 The embodiment of a plate heat exchanger shown schematically in FIG. 1 shows in perspective a plate stack S composed of a plurality of shaped individual plates 1, which are each connected to one another to form a plate pair P.
  • Each individual plate 1 comprises a floor 11 which lies in a different plane than the longitudinal edges 12.
  • each individual plate 1 is each with a Contact surface 13 formed, which is offset in height from the longitudinal edges 12.
  • the offset between the contact surface 13 and the associated longitudinal edge 12 is twice as large as the offset between the longitudinal edges 12 and the bottom 11.
  • the bottom 11 is therefore located in the middle between the plane of the longitudinal edges 12 and the plane of the contact surfaces 13.
  • transverse edges 14a and 14b are diagonally opposite one another.
  • FIG. 1 Two of the individual plates 1 shown as the uppermost part in FIG. 1 are connected to plate pairs P according to the lower representation in FIG. 1.
  • Fig. 1 five complete plate pairs P are shown, with a single plate 1 being arranged on the top pair of plates, which is also connected to the top single plate 1 shown at a distance to form a plate pair P.
  • the plate pairs P are connected in the area of the contact surfaces 13 to form the plate stack S, superimposed channels result for the two media participating in the heat exchange. While one medium flows in the flow channels, which are each formed by the plate pairs P, the other medium flows in the flow channels, which result from the joining of the plate pairs P to the plate stack S.
  • the transverse edges lying in the plane of the longitudinal edges 12 14a of the individual plates 1 here form the inflow cross section Z 1 or the outflow cross section A 1 of the flow channels for the medium flowing between the plate pairs P.
  • Fig. 1 which shows a counterflow heat exchanger, shows that due to the diagonal arrangement of the inlet and outlet openings, the inflow cross sections Z1 and Z2 for one medium next to the outflow cross sections A2 and A1 for the other medium, respectively offset by half a height of a pair of plates P.
  • the plate heat exchanger shown in perspective in FIG. 2 has two media I and II flowing through it in direct current, medium I being, for example, the heat-emitting medium and medium II the heat-absorbing medium.
  • medium I being, for example, the heat-emitting medium and medium II the heat-absorbing medium.
  • the heat exchange between the two media I and II takes place in plate stacks S which, according to FIG. 1, are formed from individual plates combined into plate pairs.
  • These plate stacks S are arranged directly next to one another in such a way that their inflow cross sections Z 1, Z 2 are perpendicularly above the outflow cross sections A 1, A 2, as the section in FIG. 2 clearly shows.
  • the inflow and outflow cross-sections belonging to one of the two media I or II are diagonally offset from one another, as can again be seen in FIG. 1.
  • the inflow and outflow cross sections Z1, Z2 and A1, A2 of each plate stack S are separated from each other by a central wall 21 which extends over the entire length of the plate stack S.
  • the middle walls 21 of adjacent plate stacks S are each connected to a common collecting duct 2 by a ceiling wall 22.
  • these collecting channels 2 represent a supply or discharge of the medium I or II to or from respectively adjacent two plate stacks S.
  • This inflow nozzle 3 1 is connected to those collecting channels 2 which open above the inflow cross sections Z 1 of the plate stack S.
  • the streams of the medium I divide and get into the collecting channels 2 formed below the plate stack S, which lead the medium I to the outflow nozzle 4 1, which is arranged in the embodiment according to FIG. 2 below the inflow nozzle 3 1.
  • the heat-absorbing medium II enters the inflow nozzle 32 from above and arrives from here into collecting channels 2, which lead to the inflow cross sections Z2 of the plate stack S.
  • the partial flows of the medium 2 are divided in the plate stacks S and arrive in collecting channels 2, which in turn lead to an outflow nozzle 42, which is formed vertically below the inflow nozzle 32.
  • the top walls 22 of the collecting channels 2 are designed to run obliquely, as can clearly be seen in the upper part of FIG. 2.
  • the in the embodiment 2 realized DC circuit of the two media I and II participating in the heat exchange enables the generation of a surface temperature on the individual plates, which avoids the caking of solids when the media I and II enter the plate stack S as well as falling below the dew point. Should deposit products of the media arise, they can be collected and discharged via the collecting channels 2 and the outlet connections 4 1 and 4 2 below.
  • the plate heat exchanger shown in Fig. 2 is accordingly particularly well suited for a recuperative heat exchange in connection with flue gas cleaning systems.
  • the plate heat exchanger in Fig. 3 is designed as a countercurrent heat exchanger, in which the heat-emitting medium I according to the dash-dotted arrows from above enters the inflow nozzle 3 1 and from this inflow nozzle 3 1 into the collecting channels 2 connected to it.
  • the heat-emitting medium I also divides in this case and emerges from the mutually spaced outflow cross sections A 1 of the plate stack S, namely in the underlying collection channels 2, which in turn are connected to the outflow nozzle 4 1 lying on the opposite side.
  • the heat-absorbing medium II enters the inflow nozzle 32 from below and passes through the corresponding collecting channels 2 to the inflow cross sections Z 2 lying on the underside of the plate stack S. After heating the medium II in the plate stacks S, it emerges from the outflow cross sections A2; it passes into the collecting channels 2 above these outflow cross-sections A2, which are connected to the outflow connection 42.
  • the inflow and outflow of the heat-absorbing medium II is indicated in Fig. 3 by solid arrows.
  • both plate heat exchangers in FIGS. 2 and 3 show that despite a very compact and space-saving design, there is good access to the plate stacks S, which not only facilitates the installation of cleaning devices that may become necessary, but also good access to repairs or Maintenance work enabled.
  • both representations show that the flow guidance of the two media I and II takes place in the shortest possible way and without any deflections causing pressure loss, so that the plate heat exchangers described, despite their compactness, are highly efficient.
