Definitions
- the invention relates to a film for a film constructed, in particular apprised by an organization, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a computerized physician, a film for a film constructed, in particular impressibly, evaporator for Transfer of a liquid mass flow of media in a gaseous media mass flow according to the preamble Of claim 1 further defined type.
- a similar, in a similar way from slides constructed catchy evaporator is in DE 44 26 692 C1.
- the described there, two-stage Evaporator unit serves to transfer one in dependence a load specification adjustable liquid reactant mass flow in a gaseous reactant mass flow, wherein the liquid reactant mass flow with the aid of a heat transfer medium in a first Stage at least partially evaporated and in a second Stage if necessary completely evaporated and subsequently overheated.
- the evaporator unit by alternately stacking of films with heat transfer channels and of Foils with reaction channels is formed, and that in each case at least a first and a second stage in a foil are integrated, the first stage as Channel with minimized cross-sectional area at the itself formed directly adjacent to the inflow line is, and that the first stage at high heat transfer rates is operated, and further that the total cross section the reaction channels in the second stage in Flow direction increases.
- the vaporized reactant mass flow from each of the Reaction or media foils in a common collection space emerge in the exit area and from there is via an outlet line of the gaseous reactant mass flow derived.
- collecting space can be a Mixing of the respective reaction films flowing reactant mass flows come, so that the Output a comparatively evenly vaporized Reactant mass flow is present.
- the object of the invention an ideal and Therefore, even distribution of the vaporized and the evaporated medium, especially in the exit area the films of a built-up of films evaporator to reach.
- the exit area is heated in the Area of the media sheets arranged so that the exit area about the pure function of a collection room goes out and a mix of over the Width of the respective media sheet exiting gaseous Media shares in the heated exit area can be done.
- a film pack 1 is one in its entirety Evaporator not shown recognizable.
- the evaporator is constructed here say butter which means that the evaporator at least two separate Inputs for two media mass flows, accordingly
- each of the foil packets 1 has a first media sheet 2 and a second media sheet 3.
- Between the two media slides 2, 3 is here one Intermediate foil 4 is arranged. These three foils 2, 3, 4 are then combined to form the film package 1.
- the film package 1 On at least two sides of the film package 1 are then more rooms 5 in which a heating medium flows or in which the thermal energy is used to heat the Foil packages 1 in any other way, for example by catalytic combustion or the like, is made available.
- a heating medium flows or in which the thermal energy is used to heat the Foil packages 1 in any other way, for example by catalytic combustion or the like, is made available.
- a conceivable one Construction would be, for example, the alternating stacking of foil packets 1 and spaces 5, like this is shown here rudimentary.
- the first media sheet 2 has one of the evaporation and / or overheating the first media stream serving Evaporation area 6, at which in the Flow direction of the media stream an exit area 7 connects.
- the evaporation region 6 points Structures, channels, aisles or the like, the not explicitly shown here, as they are in themselves known and for the invention of minor interest are.
- the exit region 7 of the first media film 2 may, but need not, be free from such Be structures.
- a comparable structure shows the second media slide 3 which also has an evaporation region 8 and has an output region 9.
- an opening 10 is arranged in the intermediate foil 4. Through this opening 10 and a recess 11 in the second media film 3 thus results in 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 embodiment shown here from the exit area 7, the opening 10 and the recess 11 exists, forms one in its entirety Outlet area 12 for the media mass flow in the first media film 2. Due to the cross-sectional enlargement will be in the region of the exit region 12, set a much lower pressure gradient than this over the run length of the media stream in the evaporation zone 6 is the case.
- Fig. 2 is now a principle cut through the first media sheet 2 and a plan view of the underneath arranged intermediate foil 4 recognizable. It is the exit area 9 of the second media film 3 is hidden indicated. He flows into one with the second Media sheet 3 corresponding collecting space 14, which all second media sheets 3 of the film packages 1 connects to each other, and which with an outlet line (not shown) for the second media stream corresponds.
- the evaporator area 6 recognizable by which the first media stream according to the direction indicated by the arrow A flow direction flows.
- the exit region 7 of the first media film 2 are then the opening 10 and arranged underneath Well 11 in the second media sheet 3, so the Exit area 12, recognizable.
- This is in his Cross-section enlarging exit region 12 corresponds with a collecting space 15, which in turn with an outlet line (not shown) for the first media stream is connected.
- the exit region 12 extends over the entire Width of the evaporation region 6 of the first media film 2, so that over the entire width of the Foliepaktes 1 the greatly reduced pressure gradient can adjust. Thus, it can be achieved that it is in this exit area 12 to a very small Pressure loss and thus to a very uniform Distribution of the flowing from the evaporation region 6 Medium is coming.
- the area in the exit region 12 is arranged in the way in the film package 1, that he, as well as the evaporation areas 6, 8 and the Exit area 9, in direct heat-conducting contact is with the rooms 5 for heating is achieved that the exit area 12 is continuously heated, which also causes the formation of "cold" dead zones Prevents flow of media mass flow and the uniform distribution and mixing of the media mass flow before entering the collecting space 15th greatly improved.
- the films 2, 3, 4 used for example to thin plates or films from a high-alloy steel material in which the recesses 11 and the structures in the evaporation areas 6, 8 are etched.
