Definitions

  • the present invention relates to an evaporator device for covering a flow cross-section of an air flow channel, as defined in the preamble of independent claim 1.
  • Evaporator devices are used in particular in humidification systems which have an air flow channel through which air flows in an air flow direction.
  • humidification systems which have an air flow channel through which air flows in an air flow direction.
  • nozzles can be used which atomize the water supplied to them into the air flowing through, wherein the nozzles can be directed both in and against the air flow direction.
  • the water becomes aerosols, i. floatable water droplets, torn, which partly go into the gaseous state and are absorbed by the air.
  • the air can not always absorb the aerosols fast enough so that water droplets of different sizes are entrained by the air flow. These can wet subsequent parts of the system, which can lead to corrosion damage.
  • droplet separation devices and / or post-evaporation devices are used, which remove the water droplets as completely as possible from the air flowing through them.
  • CH-A-673 519 a device which has a flow cross section of the Air flow channel completely covering Nachverdunsterelement of a material having a spongy structure, such as ceramic.
  • the entrained in the air flow water droplets are taken on impact with such Nachverdunsterlus of the spongy structure and partially evaporated by this.
  • a disadvantage of this device is its high air resistance and the associated loss of power. To compensate for this power loss, larger humidifiers with higher energy requirements must be used.
  • an evaporator device which was developed to remedy this disadvantage and has a smaller air resistance.
  • this evaporator device at least two plates of hygroscopic material having an open-pore foam structure which are each completely covering the flow cross-section of the air flow channel are arranged spaced from each other in the air flow direction.
  • the at least two plates each have a number of openings in the flow direction of the air, wherein the openings of one plate are offset from the openings of an adjacent plate. Thanks to these openings, through which a part of the air flows, the pressure loss of the air flow through the evaporator device is considerably reduced. On the back of the plates, however, can be torn by the flow of air drops of water that have been previously driven through the through holes.
  • 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 are arranged obliquely to the air flow direction and spaced from each other so that they overlap in a vertical overlap area without contact. It is disadvantageous that each individual plate element is surrounded by a frame, wherein the frames have to ensure the discharge of the excess water downwards.
  • the invention has the following object.
  • To create is an evaporator device of the type mentioned, the water drops from air flowing through and evaporates, with optimal evaporation performance of the pressure loss of the air flow should be as low as possible.
  • the evaporator device should advantageously be adaptable in a simple manner to different flow cross sections of air flow channels.
  • An evaporator device covers a flow cross-section of an air flow passage through which air flows in an air flow direction containing water in droplet form.
  • the evaporator device has at least two porous, open-pore evaporator plates arranged one above the other. These evaporator plates are obliquely arranged to the air flow direction and spaced from each other so that they are in one Overlap vertical overlap area without contact. Horizontally adjacent to said evaporator plates at least two further Verdunsterplatten are arranged obliquely to the air flow direction, which also overlap contactless in a vertical overlap region and overlap the horizontally adjacent Verdunsterplatten each in a horizontal overlap area without contact.
  • the water droplets leading air flows in the inventive evaporator device to a part through the evaporator plates, whereby the water droplets are retained by the Verdunsterplatten and remain in these. This remaining water is evaporated in the subsequent flowing through the evaporator plates air or drains down.
  • the inventive evaporator device makes it possible to cover the flow cross-section of the air flow channel and thus removing and evaporating the water droplets of the air stream from the air stream, without causing the evaporator device too large pressure losses.
  • the vertical and horizontal overlap of the evaporator plates ensures that the water flow from one edge of a front evaporator plate in the overlap area collects water droplets from an adjacent rear evaporator plate.
  • the upper evaporator plate is arranged in the air flow direction in front of the lower evaporator plate.
  • water which is not evaporated in the air flow, flows in such a tile roof-shaped arrangement of Verdunsterplatten by gravity and the air flow in the Verdunsterplatten first to the lower rear edges, is torn off from there and meets in the overlapping area on the lower adjacent evaporator plates, so that no water droplets reach the area of the air flow channel behind the evaporator device.
  • such an arrangement ensures sufficient deflection of the portion of the air flow, which is deflected.
  • the evaporator plates are each arranged in the overlapping areas with their horizontally adjacent Verdunsterplatten either in the air flow direction in front of all these horizontally adjacent Verdunsterplatten or arranged in the air flow direction behind all these horizontally adjacent Verdunsterplatten.
  • Such an arrangement ensures on the one hand a sufficient deflection of the part of the air flow, which is deflected, and on the other hand prevents short circuits in which the air flow can penetrate the evaporator device unhindered.
  • the arrangement of the evaporator plates is rotated by 90 ° or 180 ° about the air flow direction.
  • Such arrangements are alternatives to the arrangement described above, which may be advantageous for certain geometric conditions.

  • the retained water from the evaporator plate which is not evaporated in the air flow, improved orderly get from an upper to lower Verdunsterplatten. In particular, it can thus be prevented that this water flows past the rear evaporator plates laterally.
  • At least one of the evaporator plates at its upper and / or at its lower end to an air guide.
  • the air flow which does not penetrate the evaporator plate, can be further deflected, so that the inertia of the water droplets works even better.

  • Such support bars allow easy and flexible mounting of the evaporator device on site.
  • the evaporator device has a planar air-guiding element for deflecting the air impinging next to the outermost evaporator plates onto the evaporator plates.
  • a flow-calmed zone can be created in the edge region of the evaporator device, from which the air is directed onto the evaporator plates. This ensures that no water droplets containing water flows through between the edge of the evaporator plates and the air flow passage wall.
  • the evaporator device comprises a collecting trough arranged below the lowermost evaporator plates and / or between evaporator plates.
  • a collecting channel or such collecting channels can be collected and discharged from the evaporator plates downwardly directed water, regardless of the formation of the bottom of the air flow channel.
  • a passage through the evaporator device is present between an upper evaporator plate and a lower evaporator plate, which passage is covered by at least one connecting element connecting the two evaporator plates.
  • the at least one connecting element ensures that the rear evaporator plate in the overlapping region flows better through in comparison to a variant without connecting element, since the air flow between the two evaporator plates and the connecting element arranged one above the other is stowed, whereby the air pressure is increased.
  • a further advantage of the at least one connecting element is that it conducts water which has not evaporated from an upper evaporator plate arranged directly underneath. This has the consequence that the lower evaporator plate is better moistened and no or at least less water is torn from the upper plate by the air flow.
  • the at least one connector is impermeable to water in droplet form. This ensures that any water droplets that are not separated during the diversion of the air flow are intercepted by the at least one connecting element.
  • the at least one connecting element is permeable to air, in particular porous and open-pored. This has the consequence that a part of the deflected air flows through the at least one connecting element. In this way, the pressure loss of the entire evaporator device is reduced.
  • the at least one connecting element is more permeable to air than the evaporator plates. This can be achieved, for example, by making the connecting element thinner or more or larger Is provided pores provided. This ensures that the pressure loss of the air flow through the connecting element is lower.
  • the at least one connecting element is airtight. The entire bypassed air then flows through the back of the overlap area evaporator plate, whereby it is flowed through optimally.
