Definitions
- the invention relates to a plate heat exchanger with flowed in cocurrent or countercurrent flow of a first and a second medium flow channels, which are formed for the first medium between each pair of plates connected to individual plates and for the second medium between assembled to a plate stack plate pairs, wherein the individual plates and the plate pairs are connected to one another at longitudinal edges and contact surfaces extending parallel to the main flow direction, wherein each individual plate has longitudinally corresponding, diagonally arranged inflow and outflow cross sections for the first medium and transversely adjacent inflow and outflow cross sections for the second medium, wherein the Abströmqueritese for the first medium are each offset by half the height of the inflow and outflow of the second medium, wherein the single plate ver with a turbulence generating profiling is seen, wherein the profiling is formed perpendicular to the main flow direction over the entire bottom to the contact surfaces, and wherein the individual plates in the region of the contact surfaces have edge channels.
- Plate heat exchangers of this type are used industrially with plate dimensions of several meters.
- One field of application here is the use in waste incineration plants, power plants, chemical plants, refineries and / or the like in which the resulting combustion heat of the flue gas is used to heat a second medium.
- a plate heat exchanger discloses in detail the German patent DE 41 42 177 C2 ,
- guide vanes are provided, which distribute the medium entering through the inflow to the full channel width of the flow channel.
- the guide vanes are provided with extended Abströmschenkeln, which protrude beyond the longitudinal center of the single plate.
- the vanes for equalizing the flow within the flow channel in the longitudinal center of the individual plates are arranged closer to the inflow cross section than in the direction of the longitudinal edge of the single plate.
- the turbulence-generating profiling which covers the largest possible area of the individual plates, serves the same purpose.
- a plate heat exchanger according to the preamble of the main claim is proposed, in which the individual plates in the region of the contact surfaces have edge channels with a size-variable cross section over their longitudinal extent.
- the edge channels according to the invention also lead, by reducing the barrier-free bypasses, to an improved flow pattern, which in turn increases the heat output of the heat exchanger.
- the edge channels are formed like a labyrinth and are in the area of the contact surfaces, d. H. formed in the edge region of the individual plates, where otherwise the heat medium would seek a barrier-free and thus interaction-free flow path.
- the variation of the cross-section over the longitudinal extension of the edge channels ensures that the medium flowing through it can not continue to flow straightforward, but suffers a congestion effect at the narrowings of the cross section.
- an interaction-free medium flow through the edge channels of the single plate and consequently also a power loss is greatly reduced. This leads to a performance increase of up to 5% over the prior art. This power increase can also be used to reduce the necessary plate length of the heat exchanger, so that the same performance can be achieved with shorter individual plates.
- the edge channels are substantially S-shaped, i. formed several s-shaped. This results in a staggered blocking embossing on both sides of each edge channel, which leads to an increased interaction of the heat medium due to the resulting constrictions and extensions.
- the cross section of the edge channels is variable by more than 50%. This reduces the barrier-free cross-section for the medium at a constriction by half or more.
- a spatially offset flow channel is created in combination with the s-shaped design, which further enhances the interaction between the medium and the heat exchanger.
- the Randkanalsaussch invention results in combination with the inventive design of the turbulence generating profiling into the respective edge region of each individual plate the synergistic effect that free flow paths for the medium are basically avoided.
- the in the Plate heat exchanger inflowing media can thus avoid a pass-like, interaction-free flow path.
- Neither the edge near the bottom of each individual plate nor in the edge region between two individual plates forming edge channel represent according to the embodiment of the invention in contrast to the prior art such Beipass entry, since the edge channels are formed according to the invention labyrinth-like and the turbulence causing profiling into the edge region is pulled into each individual plate.
- a performance increase or with the same power a reduced plate size can be achieved. For such a configuration, there is no model in the prior art.
- the invention provides that the onflow limbs and the outflow limbs have an angle between 140 ° and 100 °, preferably 135 ° and 112 ° to each other.
- angling of up to 90 ° is thus also possible, without the risk of blockages of the inflow cross sections due to foreign substance deposits on the guide vanes.
- the individual plates within an inlet region formed by embossments, projecting into the flow channel guide vanes, wherein the guide vanes arcuately formed with a substantially parallel to the main flow direction aligned inflow leg and at an angle to the inflow leg aligned Abströmschenkel, wherein the turbulence generating Profiling of the individual plates has pronounced nubs.
- the nubs can be produced very easily and inexpensively by embossing the individual plates.
- a uniform pimple field is also ideally suited to increase the performance of the heat exchanger. Due to the turbulent flow of heat transfer is increased and thus improves the efficiency.
- nubs may be formed as spacers for adjacent individual plates.
- spacers can also be formed in the region of the guide vanes to the individual plates in the area of the inflow and Keep outflow cross sections at the specified distance from each other.
- all nubs can serve as spacers.
- the guide vanes of the inflow cross sections do not protrude beyond the longitudinal center of the individual plates, i. the vanes are formed exclusively in the plate halves assigned to the respective inflow cross sections, the inflow limbs and the outflow limbs of the vanes having substantially equal lengths, and wherein the inflow limbs of the vanes are respectively arranged directly on the transverse edges of the individual plates running essentially perpendicular to the main flow direction. Due to the shorter, steeper to the main flow direction and closer to the edge arranged vanes, the adhesion of the dirt particles is minimized. This reliably prevents clogging of the inflow cross sections, which would otherwise result in expensive cleaning.
- the turbulence-generating profiling in the region of the inflow cross-sections project up to the guide vanes and be recessed in the region of the outflow cross-sections.
- plate half creates a negative pressure relative to the gas pressure within the profiled inflow cross-section, whereby suction of the inflowing flue gas is effected in the profile-free area.
- a homogeneous distribution of the inflowing medium is effected on the entire plate width, which in turn positively affects the performance of the plate heat exchanger.
- the guide blade design according to the invention on the one hand and the inventive design of the turbulence generating profiling on the other hand provide in combination the synergistic effect that a homogenization of the incoming media in the plate heat exchanger on the entire plate width, while minimizing the risk of leading to blockages in the worst case Contamination of the vanes.
- This is in contrast to the prior art according to the aforementioned DE 41 42 177 C2 with the invention deliberately in contrast to the previous embodiment proposed to reduce the guide vanes, in particular with regard to the respective discharge limb.
- the number of vanes has been significantly reduced.
- the plate heat exchanger according to the invention in contrast to previously known plate heat exchangers, is less susceptible to soiling or even blockage, as a result of which the operational reliability is increased and / or maintenance intervals can be made larger. In this context, it has a particularly positive effect that the outflow legs of the guide vanes according to the invention, in contrast to the prior art, are much steeper and much shorter.
- the guide vanes are completely embossed, so that these rest without gaps on the adjacent individual plate.
- the guide vanes serve completely as a support or as a spacer, so that vibrations within the plate pairs and within the plate stack are reduced and thus the overall construction of the heat exchanger becomes more stable.
- the fully stamped guide vanes may rest on the guide vanes of adjacent individual plates or on the opposite wall of the flow channels.
- FIG. 1 schematically illustrated embodiment of a plate heat exchanger shows in perspective a plate stack S of a plurality of stamped individual plates 1, which are each connected to a pair of plates P.
- Each individual plate 1 comprises a bottom 11, which lies in a different plane than the longitudinal edges 12.
- each individual plate 1 is in each case formed with a contact surface 13, which is offset in height relative to the longitudinal edges 12.
- the offset between the abutment 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 floor 11 is therefore in height in the middle between the plane of the longitudinal edges 12 and the plane of the contact surfaces 13.
- transverse edges 14a and 14b, in height, ie perpendicular to the surface of the bottom 11 are offset by the same amount as the planes in which on the one hand the longitudinal edges 12 and on the other hand the contact surfaces 13 lie.
- the FIG. 1 clearly shows that in this case the transverse edges 14a and 14b are diagonally opposite each other.
- FIG. 1 Two of each in FIG. 1 As a top part illustrated individual plates 1 are shown in the lower illustration in FIG. 1 connected to plate pairs P. In FIG. 1 five complete plate pairs P are shown, wherein on the uppermost plate pair still a single plate 1 is arranged, which is also connected to the spaced top single plate 1 to a pair of plates P.
- the plate pairs P are connected in the region of the contact surfaces 13 to the plate stack S, resulting superimposed channels for the two participating in the heat exchange media. While a medium flows in the flow channels, the 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 14b of the individual plates 1 running in the plane of the abutment surfaces 13 form the inflow cross sections Z2 and the outflow cross sections A2 for the other medium, which flows between the individual plates 1 of each plate pair P either in the same or in the opposite direction to the first medium.
- the FIG. 1 which shows a countercurrent heat exchanger, can be seen that due to the diagonal arrangement of the inlet and outlet openings, the inflow Z1 or Z2 for the one medium next to the outflow sections A2 and A1 for the other medium, each by half Height of a pair of plates P offset.
- FIG. 2a shows a single plate 1 according to the invention, the Zuströmquerites Z1 extends over half the width of the single plate 1, from the longitudinal center to the longitudinal edge 12.
- the single plate has an inlet region E whose length in the main flow direction characterizes the distance which the inflowing medium requires in order to be distributed over the full width of the single plate 1.
- four guide vanes 2 are arranged to the right next to the longitudinal center of the single plate 1, which each have an inflow leg 21 and a discharge limb 22.
- the on-stream legs 21 and outflow legs 22 are approximately the same length and enclose an angle of approximately 140 ° to 100 ° between them. In this case, none of the outflow limb 22 projects beyond the longitudinal center of the single plate 1.
- the on-stream legs 21 are each mounted in the immediate vicinity of the transverse edge 14a.
- the single plate 1 has over its entire width up to the contact surfaces 13 a turbulence generating profiling 31, 32.
- This profiling 31, 32 consists of a large number of embossed nubs 31, 32 embossed in the single plate 1, which extend in the region of the inflow cross section Z1 as far as the guide vanes 2 and are recessed in the area to the left of the longitudinal center.
- S-shaped edge channels 15 formed with a size variable over its longitudinal extension cross-section.
- FIG. 2b can be seen in a perspective view one of a plurality of individual plates 1 plate stack S formed. The interaction of the individual plates 1 can be taken from this presentation well.
- FIG. 3 shows such an enlarged edge channel 15 shown in plan view.
- the Figures 4 a, 4 b and 4 c show sectional views of this edge channel 15 at different interfaces A, B and C according to FIG. 3 . It can be seen that the cross section through which the medium can flow is at maximum point A, while the cross section at points B and C is only about 50% or less of the maximum cross section, the cross section at points B and C respectively is narrowed to different sides of the edge channel 15. This results in the constrictions due to impressions 33, which with respect to the image plane after FIG. 3 are formed part-circular, resulting in the total longitudinally s-shaped channel shape.
- the invention works in such a way that the heat medium, in this case flue gas, flowing into the single plate 1 through the inflow cross section Z1, meets the on-stream leg 21 of the guide vanes 2, which adjoins the transverse edge 14a directly. From there, the flue gas is passed to the outflow legs 22, which are at an angle of about 140 ° to 100 ° to the on-stream legs 21.
- the heat medium in this case flue gas
- the inlet region E in the region of the inflow Z1 has a directly following the vanes 2 profiling 31, 32, while in the mirror-symmetrical left of the longitudinal center region of the inlet plate 1 no profiling is formed above the profiling 31, 32 within the inlet region E from a pressure distribution, which sucks the inflowing flue gas from the guide vanes 2 in the profile-free area.
- the flue gas is distributed uniformly over the plate width and ensures a homogeneous heat output over the entire inlet plate 1 of the heat exchanger. Due to the particularly short and steep design of the guide vanes 2, the adhesion of dirt particles to the guide vanes 2 is reduced, so that a blockage of the inflow Z1 is prevented. Overall, thus creating a low maintenance plate heat exchanger, which requires no loss of performance.
- the single plate 1 in addition to the measures described above edge channels 15, which has indentations 33 for the purpose of a labyrinth education. This flows into the edge area the single plate 1 reaching medium through the edge channels 15 through and strikes the constrictions and extensions of the respective channel cross-sections, which cause a congestion effect and lead to a higher interaction of the medium with the single plate 1.
- the flue gas enters the S-shaped cut edge channels 15, where it is in the section A (view FIG. 4 a) the entire channel cross-section has available.
- the flue gas In the area of section B (view FIG. 4 b) the flue gas must flow through the first bend, in which the cross-section is reduced by half. This creates the aforementioned congestion effect.
- the cross-section then expands again for a short time in order to reach the region C (FIG. FIG. 4c) again to reduce to half, but this time the s-shape of the edge channel 15 following in the region of the opposite channel side wall.
- the turbulence generating profiling 31, 32 is formed over the entire width of the individual plates 1 up to the contact surfaces 13. This helps avoid by-passes and thus improves the performance of the heat exchanger.
