Definitions
- the invention relates to a film for a film constructed, especially two-course, evaporator for Transfer of a liquid media mass flow into a gaseous media mass flow according to that in the preamble Art defined by claim 1.
- a corresponding, in a comparable way from foils built-up single-line evaporator is in DE 44 26 692 C1.
- the two-stage described there Evaporator unit is used to transfer one depending a load specification adjustable liquid reactant mass flow into a gaseous reactant mass flow, where the liquid reactant mass flow with the help of a heat transfer medium in a first Stage evaporated at least partially and in a second Stage may be completely evaporated and is then overheated.
- the evaporator unit by alternating stacking of foils with heat transfer channels and of Sheets with reaction channels is formed, and that in each case at least a first and a second stage in a film are integrated, the first stage as Channel with minimized cross-sectional area on the directly connected to the inflow line and that the first stage at high heat transfer coefficients is operated, and further that the total cross section of the reaction channels in the second stage in Flow direction increases.
- the vaporized reactant mass flow from each of the Reaction or media slides in a common collecting room Exit in the exit area and from there the gaseous reactant mass flow is via an outlet line derived.
- arranged collecting room can be a Mixing the from the respective reaction foils flowing reactant mass flows come, so that on Output a comparatively evenly evaporated Reactant mass flow is present.
- the object of the invention to be ideal and therefore even distribution of the evaporated and of the vaporized medium, especially in the outlet area the foils of an evaporator constructed from foils to reach.
- this task is characterized by Features mentioned in claim 1 solved.
- the exit area in the heated Area of the media films arranged so that the exit area about the pure function of a collecting room goes beyond and a mix of the Width of the respective media film emerging gaseous Media shares in the heated outlet area can be done. This results in a very even one Distribution of the evaporating in the respective film Medium before this the film into a collection room which then leaves several such foils and connects an outlet line with one another.
- a foil package 1 is one in its entirety Evaporator not shown can be seen.
- the evaporator has a two-course design here. This means that the evaporator has at least two separate ones Has inputs for two media mass flows, accordingly here each of the foil packs 1 has one first media film 2 and a second media film 3. There is one between the two media foils 2, 3 Intermediate film 4 arranged. These three slides 2, 3, 4 are then combined into the foil package 1.
- the first media film 2 has one of the evaporation and / or overheating the first media stream Evaporation area 6, on which in the Direction of flow of the media stream an exit area 7 connects.
- the evaporation area 6 has Structures, channels, corridors or the like on the are not explicitly shown here because they are in themselves known and of minor interest for the invention are.
- the exit area 7 of the first media film 2 can, but need not, be free of such Structures.
- the second media film shows a comparable structure 3 which also has an evaporation area 8 and has an exit area 9.
- an opening 10 is arranged in the intermediate film 4. Through this opening 10 and a recess 11 in the second media film 3 there is thus a strong cross-sectional enlargement in the area of the exit area 7, compared to the evaporation area 6.
- This area of cross-sectional enlargement which in the embodiment shown here the exit area 7, the opening 10 and the depression 11 exists, in its entirety forms one Outlet area 12 for the media mass flow in the first media film 2.
- its evaporation area 8 here has a shorter barrel length than the Evaporation area 6 of the first media film 2 such an enlargement of the cross section in the area the exit area 9 due to technical Conditions that do not relate to the invention and which are not to be explained further here, not wanted. In principle, however, it would also be here conceivable, for example by introducing one dotted indicated recess 13 in the intermediate film 4, a comparable to the exit area 12 Creating area.
- the evaporator area is in the first media film 2 6 recognizable by which the first media stream according to the direction of flow indicated by arrow A. flows.
- This one in his Exit area 12 enlarging cross section corresponds with a collecting room 15, which in turn with an outlet line (not shown) for the first media stream is connected.
- the exit area 12 extends over the entire Width of the evaporation area 6 of the first media film 2, so that over the entire width of the Film package 1 the greatly reduced pressure gradient can adjust. It can thus be achieved that in this exit area 12 to a very small Pressure loss and thus to a very even Distribution of the flowing out of the evaporation area 6 Medium is coming.
- the good uniform distribution also makes a "Backflow" of the flow into the evaporator area 6 prevented, which otherwise in particular in the Collection space 15 facing away from the end of the exit area 12 or the evaporation area 6 could occur.
- This can cover the entire area of the evaporation area 6 for the intended task, namely the transfer of the liquid media mass flow in the gaseous Media mass flow, what used ultimately better power transfer per unit area enables, and which in turn becomes one smaller overall space for the evaporator.
- increased material tensions due to a very high Temperature gradients in the area of standing medium in the foil package 1 can be prevented or at least be reduced.
- the area in the exit area 12 is arranged in the manner in the foil package 1 that he, as well as the evaporation areas 6, 8 and the Exit area 9, in direct heat-conducting contact with rooms 5 for heating is achieved that the outlet area 12 is continuously heated, which also leads to the formation of "cold" dead zones in the Flow of the media mass flow prevented and the even distribution and mixing of the media mass flow before entering the collection room 15 greatly improved.
- the output areas 7, 9 only corresponding depressions incorporated and on an opening 10 in the Intermediate film 4 can be dispensed with, so that a same run length of the media mass flows in the two Media slides 2, 3 would be conceivable.
- the foils 2, 3, 4 used can be, for example to thin sheets or foils from one act high-alloy steel material in which the recesses 11 and the structures in the evaporation areas 6, 8 are etched.
