Definitions

  • the invention relates, preferably as a steam-heated thickener heat exchangers intended for sugar solutions for heat exchange between two separate media with a plurality of plate pairs, each consisting of two circumferential at their edge welded individual plates and formed into a plate stack with each other sealed plate pairs are joined together, the one Medium through the channels formed by the individual plates and the other Medium through the channels formed between adjacent pairs of plates flows.
  • the object of the invention is to further develop such heat exchangers with the aim of simpler maintenance and, if necessary, repair and a modular structure for the purpose of easier adaptation to different circumstances and output sizes.
  • the solution to this problem by the invention is characterized in that the plate stack is arranged in a housing which is provided with at least one inlet connection and at least one outlet connection for the medium acting on the channels formed between adjacent plate pairs, and in that the individual plates are each provided with At least one inlet opening and at least one outlet opening are provided, which are connected in a sealed manner to the corresponding openings in the single plate of the adjacent plate pair to form inflow and outflow connections for the other medium.
  • the individual plates to form a pair of plates at their edge with each other are welded all around, it is according to further features of the Invention possible, the individual plates of the plate stack either on the edge of their Weld openings together or by only the individual Seals around the opening to seal against each other, d. H. removable to execute. Except for a fully welded plate stack thus it is also possible to manufacture a stack of plates, the individual one Plate pairs can be taken apart for maintenance, for example.
  • the heat exchanger is used as a steam-heated thickener, can each single plate according to another feature of the invention except at least one inlet opening for the steam and at least one outlet opening for the condensate at least one additional opening for the outlet of inert gases.
  • the connection of adjacent individual plates of the Plate stack here either takes place with respect to the additional openings by welding the edges of the opening or only the individual Seals surrounding the opening.
  • the single plate with their entry, exit and, if necessary, additional openings to both Plate axes are symmetrical. This has the advantage that the plate stack can be made from identical individual plates, so that only one tool is required for the production of the individual plates and only one type of plate is kept in stock for the production of heat exchangers must become.
  • each individual plate is in the designed essentially rectangular and with two arranged on their narrow sides Entry openings and in the middle of their long sides with each an opening serving as an outlet or additional opening.
  • the stack of plates arranged in the container is in a preferred embodiment of the invention in the vertical direction from that of the container Medium flows through the inlet and outlet ports.
  • a Such a configuration can be according to a further feature of the invention several stacks of plates, preferably one above the other in the container to be ordered. While with stacks lying directly on top of each other the vapors must exit laterally, at a distance from one another lying stacks also from the space between the stacks To leave the brothers.
  • the container Arrange the bulkhead on which the or the stack of plates by means of clamping elements and is attached to a pressure plate.
  • the bulkhead is not used here only the fastening of the plate stack, but divided according to another Feature of the invention, the container in a steam supply space and the vapor space or plates containing the stack of plates.
  • the inlet and outlet openings in the supporting wall and, if appropriate, additional openings in the individual plates corresponding openings are provided, there is a particularly simple arrangement of the Plate stack on the supporting wall, the one with the exit and, if necessary Additional openings corresponding openings with a condensate or Inert gas line to be connected.
  • Those used to attach the stack of panels to the bulkhead Clamping elements can be arranged outside and / or inside the plate stack will. Furthermore, it is possible according to the invention, the clamping elements to be arranged in the area of the openings in the individual plates, which makes the possibility arises, these clamping elements also as guides for the individual plates train so that their attachment to the supporting wall is facilitated.
  • the heat exchanger is designed as a steam-heated thickener for sugar solutions. It has a housing 1, which is vertical in the exemplary embodiment standing cylindrical drum is designed with an axial direction extending support wall 2 is provided, which the interior of the housing 1 according to FIG. 2 divided into a steam supply space 1a and a vapor space 1b. In the area of the steam supply chamber 1 a, the housing 1 has an inlet connection 3 provided for the steam.
  • three plate stacks are on the front of the support wall 2 4 arranged, which in the embodiment of Figures 1 and 2 each by four clamping elements 5 using a pressure plate 6 are attached.
  • the three plate stacks 4 are spaced one above the other.
  • Each plate stack 4 is formed from a plurality of individual plates 7, for example according to the embodiment of Figures 3 and 4.
  • the single plate 7 is substantially rectangular and provided with two inlet openings 7a arranged on their narrow sides.
  • each individual plate 7 has in the region of the center of its long sides an outlet opening 7b and an additional opening 7c. How in particular Fig. 3 reveals, the single plate 7 is in terms of their entry, exit and Additional opening 7a, 7b, 7c formed symmetrically to both plate axes.
  • each inlet opening is located 7a of the plate stack 4 via a corresponding opening in the supporting wall 2 with the steam supply chamber 1a of the housing 1 in connection.
  • steam supplied via the inlet connection 3 enters the channels between the individual plates 7 of each pair of plates are formed. That steam serves to thicken the sugar solution supplied to the housing 1; the residual steam or the condensate is discharged through the outlet openings 7b (see FIG. 3) deducted by a corresponding, formed in the support wall 2 Opening are connected to a condensate line 9.
  • the one in the single plates 7 formed additional openings 7c are above a corresponding opening in the support wall 2 with an inert gas line 10 in connection.
  • Fig. 1 further shows that the sugar solution the vapor space 1b of the housing 1 is fed through a feed line 11 which is in a juice distributor 12 flows.
  • the sugar solution emerges from the underside of this juice distributor 12 in the form of fine rays that hit the top of the top stack of plates 4 hit and stack this plate from top to bottom through those Flow through channels formed by adjacent plate pairs will.
  • the sugar solution is through the steam flowing inside the plate stack is thickened.
  • the one here emerging vapors emerge from the side as well as above and below Plate stack 4 out. You are at the top of the housing 1 by one Vapor connector 13 deducted.
  • the one above the other Supporting wall 2 attached plate stack 4 in particular for cleaning them with the sugar solution loaded channels removed from the support wall 2 are formed by the clamping screws in the exemplary embodiment Clamping elements 5 released and the pressure plates 6 removed, so that the plate stack 4 can be removed from the support wall 2. Since at Embodiment according to Figures 3 and 4, the individual plate pairs exclusively sealed with the help of the clamping elements 5 and the pressure plate 6 are held together is a disassembly of the individual plate stacks 4 possible in pairs of plates, so that the channels acted upon by the sugar solution can be easily cleaned.
  • FIGS. 5 and 6 thus results in a stack of plates 4 from fully welded individual plates 7, which, however, just like the plate stack 4 from the individual plates 7 shown in FIGS. 3 and 4 from the Support wall 2 removed and cleaned outside of the housing 1 can.
  • FIG. 7 shows one the first embodiment of Figures 3 and 4 similar training.
  • the openings 7a, 7b and 7c of the individual plates 7 become more adjacent Plate pairs through seals 8 compared to that of the sugar solution flowed through channels sealed when the plate pairs using the Clamping elements 5 and the pressure plate 6 releasably attached to the support wall 2 will.
  • Fig. 7 shows that it is possible in this embodiment, inside of the inlet openings 7a, guide holes 7d in the individual plates 7 to train. These guide holes 7d are used to weld the plate pairs Individual plates 7 threaded onto the clamping elements 5 so that they Clamping elements 5 also serve as guides for the individual plates 7 when these are releasably attached to the support wall 2.
