Definitions
- the invention relates to a film package for a two-course Evaporator made of foils for transfer of two media mass flows from one liquid State in a gaseous state after the in The preamble of claim 1 defined in more detail.
- evaporators constructed from foils are known and described for example in DE 44 26 692 C1.
- the two-stage described there - however not double flow - evaporator unit is used for transfer one adjustable depending on a load specification liquid reactant mass flow into one gaseous reactant mass flow, the liquid Reactant mass flow using a heat transfer medium evaporated at least partially in a first stage and in a second stage, if necessary, completely evaporated and then overheated.
- the evaporator unit by alternately stacking foils with one another Heat transfer channels and foils with reaction channels is formed, and that in each case at least a first and a second stage is integrated in a film, the first stage being a channel with a minimal cross-sectional area, directly to the inflow pipe connects, is formed, and that the first stage is operated at high heat transfer coefficients, and further that the total cross section of the reaction channels increases in the direction of flow in the second stage.
- the general state of the art knows so-called two-course evaporator.
- the Evaporator which is heated by a heat transfer medium or exposed to direct heating is, two separate rooms for the vaporization of two separate reactant mass flows or media mass flows having.
- Each of the areas has at least one separate entrance area for each medium, if the two media flows are already Mix in the exit area of the evaporator and flow out through a common exit area, you'd still get from double-flow vaporizers speak.
- the invention is therefore based on the object Foil package for a two-course film Evaporator to create that with a simple and space-saving construction as uniform as possible Distribution of the supplied thermal energy enables and thus with a small size of the evaporator a high evaporator output evenly can transmit.
- this task is characterized by Features mentioned in claim 1 solved.
- the foil package for the two-course evaporator offers especially when it comes to one evaporator heated with a gaseous heat transfer medium acts. Then there is a risk of overheating of these areas, which are not affected by the media flow can be cooled, less than one comparable to a liquid heat transfer medium heated evaporator.
- Fig. 1 shows the structure of a film package 1 for one constructed from foils, not in its entirety shown evaporator.
- This foil package is about a liquid or gaseous medium or via a for example catalytic combustion thermal Energy supplied.
- This supply of thermal energy is indicated by the arrows Q in Fig. 1.
- the film package 1 is made up of two media films 2, 3.
- the two media slides 2, 3 are in this one illustrated embodiment by an intermediate film 4 separated from each other.
- gears 5 can for example by an etching process from, for example made of a high-alloy steel material Foil can be etched out. In these in the media slides 2, 3 introduced gears 5 then flows respective medium.
- the media room which is formed by the corridors 5 the first media film 2 for one of the provided two media mass flows during the Media room in the second media film 3 for the other of the two media mass flows is provided.
- a conceivable structure for the film package would be one that in which the media film 2, 3 in at least one direction lying in the plane of the media film 2, 3 by about half the distance between each Centers of raised areas 6 between the Corridors 5 of the respective media film in this direction are shifted towards each other.
- these projection surfaces are the raised ones Areas of the two media slides shown.
- This in vertical Direction to the plane of the films 2, 3 shown Projection area of the respective raised areas shows that the raised areas 6 evenly and are arranged alternately in such a way that at least a large part of the respective gears 5 at least approximately evenly over the area of the two media films 2, 3 is distributed.
- This from the Corridors 5 and the raised areas 6 formed Structures cover a large part of the area of media foils 2, 3.
- the raised areas 6 should thereby a very large proportion of the area of each Cover media film, but at least one Third of the area of the two media films, which with the structures are provided.
