Definitions
- the present invention relates to an evaporator device for covering a flow cross-section of an air flow channel, as stated in the preamble of the independent claim 1 is defined.
- Evaporators are used especially in humidification systems used, which have an air flow channel, flows through the air in an air flow direction.
- humidification systems which have an air flow channel
- There are several ways to humidify the air For example, nozzles can be used which the atomize supplied water into the air flowing through, the nozzles both in and against the air flow direction can be directed.
- the water becomes too Aerosols, i. floating water drops, torn, the partly pass into the gaseous state and of the Be taken in air.
- the aerosols can not always do the air pick up quickly enough so that drops of water are different Size be entrained by the air flow. these can wet subsequent parts of the system, resulting in corrosion damage can lead.
- Droplet separation devices and / or post-evaporation devices used, the water drops as completely as possible Remove from the air flowing through.
- Such devices of various kinds belong to the state of the technique.
- CH-A-673 519 there is a device discloses a flow cross section of the Air flow channel completely covering Nachverdunsterelement made of a material with a sponge-like structure, like about ceramic, includes.
- the entrained in the air flow Water droplets are on impact with such Nachverdunsterlus taken up by the sponge-like structure and partially evaporated from this.
- a disadvantage of this device is their high air resistance and the associated Power loss. To compensate for this loss of power, need larger humidifiers with higher energy requirements be used.
- an evaporator device which was developed to remedy this disadvantage and has a smaller air resistance.
- At least two are the flow cross-section the air flow channel each completely covering Plates of hygroscopic material with open-pore Foam structure in the air flow direction spaced from each other arranged.
- the at least two plates each have a number of openings in the flow direction of the air on, wherein the openings of a plate opposite to Openings of an adjacent plate are offset. Thanks to this Openings, through which a part of the air flows, becomes the Pressure loss of the air flow through the evaporator device considerably reduced.
- On the back of the plates however, can water droplets are torn loose by the air flow, previously driven through the through holes are.
- DE-U-201 18 140 discloses an evaporator device with a plurality of porous plate elements arranged one above the other, which are pivotally mounted.
- the plate elements can be a Take position in which they obliquely to the air flow direction and are spaced from each other so that they Contactless in a vertical overlapping area overlap.
- the disadvantage is that every single plate element surrounded by a frame, the frames being the derivative ensure the excess water down to have.
- the invention is the following Task based.
- To create is an evaporator device of the type mentioned, the water droplets from flowing through Air is removed and evaporated, being at optimum Evaporation performance of the pressure loss of the air flow as possible should be low.
- the evaporator should with advantage in a simple way to different Flow cross sections of air flow channels adaptable be.
- An evaporator device covers a flow area of an air flow channel through, in an air flow direction Air flows containing water in droplet form.

These Evaporator plates are inclined to the air flow direction and arranged so spaced apart that they are in one Overlap vertical overlap area without contact. Horizontal adjacent to said evaporator plates at least two more evaporator plates at an angle to Air flow direction, which is also in a Overlap vertical overlap area without contact and the horizontally adjacent evaporator plates each in one overlap horizontal overlap area without contact.
- the water droplets leading air flows in the inventive Evaporator to a part through the evaporator plates, causing the water droplets from the evaporator plates be held back and remain in these. This remaining water is in the following by evaporating or flowing the evaporator plates flowing air down from.
- the air flows at the at least one in the overlap area front evaporator plate under deflection past.
- the inertia of the water droplets guided in the air stream causes them to be separated from the diverted air and at least one in the overlap area get to the rear evaporator plate where they turn evaporate or drain down.
- the inventive evaporator device allows the Cover flow cross-section of the air flow channel and so that the water droplets of the air flow from the air stream too remove and evaporate without removing the evaporator causes too large pressure losses.
- the upper evaporator plate in the direction of air flow in front of the lower evaporator plate arranged.
