Definitions

  • the invention relates to an apparatus for humidification with a housing having a horizontal axis, axially flowed through by the air to be humidified and with a humidifying device comprising a container for a Befeuchtungsillonkeit and a dipping into the liquid bath of the container, extending into the housing, comprising circulating carrier for the moistening liquid.
  • a trough for a liquid bath is flanged to the underside of a horizontal flow channel for the air to be humidated, which receives a frame with pulleys for an endlessly guided around these pulleys belt, which by a Opening in the bottom of the flow channel protrudes into this.
  • the porous band immersed in the liquid bath which is driven by a pulley connected to a geared motor, picks up dampening fluid from the fluid bath and delivers it to the flow channel, where the absorbed dampening fluid at least partially evaporates and is taken up as vapor from the airflow.
  • a disadvantage of this known device for humidification is especially that the running transversely to the flow direction of the air to be humidified band represents a significant flow resistance, especially since the air flow must enforce the tape both in an ascending as well as in a descending Trum. Presentation of the invention
  • the invention is therefore the object of a device for humidification of the type described with simple structural means in such a way that an effective humidification can be ensured without having to take a substantial increase in the flow resistance in purchasing.
  • the carrier is designed as a rotor with a housing coaxial axis of rotation and a plurality of distributed around the circumference of the rotor lamellae, which are parallel to the axis of rotation, form between them axial flow channels for the air to be humidified and extend over a radial region whose outer radius is greater than the distance of the axis of rotation of the rotor from the mirror of the liquid bath.
  • the wettable surface can be adapted to the respective requirements via the axial length of the lamellae, so that constructive influence on the performance of such a humidifier can be taken in several respects.
  • the individual lamellae In order to ensure the wetting of the individual lamellae distributed over the circumference of the rotor during a rotor revolution, the individual lamellae must at least partially submerge in the liquid bath. This means that the slats on a - O ⁇
  • Radial region must extend whose outer radius is greater than the distance of the axis of rotation of the rotor from the mirror of the liquid bath.
  • the lamellae can be provided with a surface structure. Particularly advantageous results are obtained in this context, when the lamellae have a blade-like cross-section, so that when immersing the lamellae in the liquid bath moistening liquid is distributed by a kind of scooping action on the lamellae.
  • the air to be humidified is removed by the evaporating humidification liquid evaporation heat, so that the air is cooled. If such air cooling is to be prevented, it is possible to provide for the humidifying liquid a heating device which can be regulated as a function of the temperature of the humidified air, via which additional influence on the air temperature can be taken if not only the heat of evaporation is replaced. However, in order to limit the absorbed moisture for higher air temperatures, it is advisable to preheat the air upstream of the rotor.
  • a UV sterilization device can be provided in the container for the moistening liquid, which can be accommodated due to the axial extent of the container over the rotor length without requiring much space.
  • the speed of the rotor can be changed.
  • particularly favorable conditions result in this context if the liquid keitsstand the liquid bath in the container in response to the humidity of the effluent from the rotor air is controlled, because in this case the wetting of the fins can be influenced. With increasing liquid level of the liquid thus the humidity is increased and lowered with decreasing level.
  • the rotor with the lamellae, between which the air to be humidified passes axially through the rotor in partial flows, is an advantageous prerequisite for cleaning the air of solid particles when these solid particles accumulate on the lamellae and are washed off the lamellae in the liquid bath .
  • the rotor may be preceded by electrodes for ionizing airborne solid particles in the direction of flow of the air to be humidified, so that the ionized solid particles are attracted to the lamellae when the potential of the lamellae is opposite to that of the ionized particles, and then with the lamellae be registered in the liquid bath.
  • with electrically non-conductive fins and the moistening liquid can be used as a counter electrode.
  • Fig. 1 shows a device according to the invention for air humidification in a simplified axial section
  • Fig. 2 shows this device in a section along the line H-II of Fig. 1 on a larger scale.
  • the device for humidification shown has a housing 1 with two connection pieces, an inlet connection 2 and an outlet connection 3, for incorporation into a flow channel which, for example, sucked in - -
  • the inlet connection 2 expands to form a cylindrical housing section 4 which receives a rotor 5 with a rotation axis coaxial with the housing section 4.
  • the shaft 6 of this rotor 5 is mounted in radially extending housing struts 7 and is driven by a geared motor 8.
  • the rotor 5 itself comprises a plurality of combined to form a ring, distributed over the rotor circumference fins 9, which extend parallel to the axis of rotation of the rotor 5 and form between them axial flow channels 10 for the air to be humidified.
  • the arrangement is made such that the slats 9 are fixed with their inner longitudinal edges on a support tube 11 and supported with their outer longitudinal edges of outer, the lamellar ring surrounding support rings 12, which, however, need not necessarily be provided.
  • the front side sealed, mounted on the shaft 6 support tube 11 is a distributor cone 13 upstream in the expanding portion of the inlet nozzle 2, so that the sucked outside air distributed over the circumference flows through the rotor 5 in the flow channels 10 between the lamellae 9 and the housing 1 through leaves the outlet 3 again.
  • the cylindrical housing portion 4 forms a container 14 for a liquid bath 15, whose mirror is denoted by 16. 2, the outer radius of the disk rim is greater than the distance of the bath mirror 16 from the axis of rotation of the rotor 5.
  • the rotor 5 therefore immersed in the region of a segment of the disk rim in the liquid bath 15, so that the slats 9 with the moistening liquid, usually water wetted. So that moistening liquid can advantageously be taken up by the lamellae 9 from the liquid bath 15, the lamellae 9 are provided with a blade-like bend 17 in the region of their outer longitudinal edge. For a better distribution of the absorbed moistening liquid over the slat surface, this can also be structured.
  • a heating device 19 is provided, which is formed in the embodiment of hot water pipes 20 which extend inside and outside of the container 14, but can also be replaced by an electrical resistance heater.
  • the heater 19 is regulated depending on the temperature of the humidified air.
  • a temperature sensor 21 is provided in the outlet port 3, which controls a control 22 with the measured actual value, for example, a mixing valve 23 between a heating flow 24 and a heater return 25 to control a target actual value comparison, that at a desired actual value difference of Actual value is returned to the setpoint.
  • a UV sterilization device 26 is also provided, which extends along the container bottom.
  • the bath level 16 can be kept substantially constant, for example, be achieved by an overflow or a level control, as both are known per se. Particularly advantageous conditions arise, however, if the filling level of the liquid bath is controlled as a function of the humidity of the air flowing out of the rotor 5 for controlling the moisture content of the air.
  • a humidity sensor 27 is provided in the region of the outlet nozzle 3, which acts on the controller 22 with the respective actual value of the air humidity.
  • a control valve 28 can be controlled for the liquid feed 29 to regulate the humidity according to a setpoint determining specification on the level height, so the mirror 16 of the bath liquid 15.
  • the air to be humidified flows through the rotor 5 in the axial direction in the flow channels 10 between the lamellae 9 wetted with wetting liquid due to the rotor rotation, wherein due to the large number of slats 9 extending in the axial direction, a comparatively large wetting area results, which is swept by the air to be humidified, so that the partial flows of the air past the wetted surfaces of the fins 9 can advantageously absorb the evaporating wetting liquid.
  • the heat of evaporation can be made available by the heater 19, which allows a constant air temperature during moisture absorption.
  • the moisture absorption can be controlled with otherwise constant parameters by the rotational speed of the rotor 5, but more advantageous is the control of the filling level of the bath liquid 15th
  • the rotor 5 also represents a good design prerequisite for the separation of solid particles from the air flow to be humidified, because these solid particles can be attracted to the fins 9 with a corresponding ionization and then washed off by the fins 9 in the liquid bath 15. For this purpose, it is only necessary to provide upstream of the rotor 5 in the housing 1 electrodes 30, which provide a sufficient electric field for the ionization of the solid particles. If the lamellar ring of the rotor 5 has a potential that is opposite to that of the ionized particles, then the solid particles are separated from the airflow in the manner described.
  • the voltage supply of the electrodes 30 is indicated in FIG. 1 by a voltage source 31 which is connected between the electrodes 30 and the housing section 4 which is electrically conductive with the rotor 5.
