- the connection of adjacent individual plates of the plate stack takes place here also with respect to the additional openings either by welding the Opening edges or by only surrounding the individual opening Seals.
- the single plate is closed two plate axes are symmetrical. This gives 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 for the manufacture of heat exchangers only kept one type of plate in stock 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 one each provided as an outlet or additional opening.
- the plate stack arranged in the housing is in a preferred embodiment the invention in the vertical direction from that of the housing via Einund Medium flows through the outlet port.
- Plate stacks are preferably arranged one above the other at a distance. While the stacks are directly on top of each other, the vapors are on the side must emerge, with stacks lying one above the other at a distance also leave the space between the stacks of vapors.
- 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 become. Furthermore, it is possible according to the invention, the clamping elements in Arrange the area of the openings in the individual panels, creating 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.
- 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 become.
- 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 become.
- 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.
