Definitions

  • the present invention relates to a liquid/water-based gas cleaning device, e.g. an air cleaning apparatus, where water constitutes the cleaning/filtering medium, i.e. an apparatus in which polluted air is forced through water in a container, and upon its forced flow through the volume of water and past internal apparatus portions, is caused to liberate and give off its contaminating particles to the replaceable water.
  • a liquid/water-based gas cleaning device e.g. an air cleaning apparatus
  • water constitutes the cleaning/filtering medium i.e. an apparatus in which polluted air is forced through water in a container, and upon its forced flow through the volume of water and past internal apparatus portions, is caused to liberate and give off its contaminating particles to the replaceable water.
  • Known water-based air cleaners are not sufficiently efficient for satisfactory cleaning of larger amounts of air, because the air follows an unsuitable air flow pattern and has a non- adjusted speed when it is in contact with the water.
  • One practical use for such water-based air cleaners is e.g. as components of air conditioners, or they may be used separately.
  • a fan preferably a suction fan disposed below a container's upwardly facing outlet opening through which cleaned air escapes into the room or is conducted further in an air conditioner.
  • Particles having a lower density than water will keep themselves floating, and particles of materials dissolvable in water, will dissolve in the water.
  • the two last-mentioned types of particles as well as dissolvable dyes from the deposited particles will gradually colour the cleaning water and, thus, indicate that it should be replaced.
  • the air cleaner may possibly be connected to a water conduit supplying water thereto.
  • the water-based air cleaner according to the invention comprises a preferably upright standing, cylindrical external container and a cylindrical internal container concentrically spaced from the external container's inner wall face and inner bottom face, the internal container having a perforated bottom wall exhibiting through-going holes.
  • the inlet sleeve for the air is orientated tangentially to the wall of the external container, and this causes a cyclone effect.
  • the air is sucked through this tangential inlet into the annulus between the inner wall face of the external container and the outer face of the internal container by means of said suction fan, from where the suction effect propagates to the lower area of the external container below the perforated bottom wall, and from there to the overlying annulus, upwards to the level of the air inlet.
  • the orientation of the holes in relation to the initial circulating movements of the air along helical paths of flow through the annulus causes a change of flow direction for the air which first is drawn downward into the water beneath the perforated bottom wall of the internal container and, thereafter, upward together with water particles brought along therewith through the vertically orientated flow holes.
  • a first obstacle e.g. in the form of a downwardly conically tapering, bowl-shaped body. Particles in the partially whirling, partially circulating air (air water mixture) hitting said first obstracle, will be prevented from being passed further upwardly and fall down into the underlying volumes of water admixed air.
  • the lowermost bowl-shaped body has uppermost as large an outer diameter as the inner diameter of the internal container and is attached to the latter.
  • the bowl body has a relatively large central aperture through which cleaned air will pass, and during this passage it may hit an upwardly tapering, conical, inverted bowl-shaped body which will stop further contamination particles which might have followed this cleaner air flow or spurts of water up to this level.
  • a filter may possibly be disposed.
  • the upright standing, external container may have an upper bell-shaped hood within which the suction fan is mounted.
  • This hood is removably disposed, so that removal of the hood creates access possibilities to the internal components.
  • Figure 1 shows a perspective view through a water-based air cleaning apparatus, in which the walls of two concentric, cylindrical containers are cut through vertically, in order to show interior accessories;
  • Figure 2 shows the cleaning apparatus in side elevation view, partially in vertical axial section, partly filled with water and with the fan out of function;
  • Figure 3 corresponds to figure 2, but here the fan is in operation and has caused water and air to be drawn up into the lower area of the internal cylindrical container;
  • Figure 4 shows a horizontal section along the line IV -IV in figure 3.
  • a water-based air cleaning apparatus comprises an upright external container 10 having a cylindrical container wall, a sealed bottom 10' and an upper bell-shaped hood 12, which is removably disposed on top of the external container's 10 upper horizontal end face.
  • the external container 10 surrounds concentrically an internal container 14 having a sealed wall and a perforated bottom 16 , the spacing being such that an annulus 18 is created between the opposed wall faces of the containers.
  • Air to be cleaned is supplied through an air inlet 22 which, according to the exemplary embodiment, extends tangentially in relation to the external container's jacket.
  • the orientation of the inlet 22 in combination with the suction effect of a fan 24 puts the air flow through the annulus 18 into a strong downward helical-shaped circulation, so that the air enters into the lower, water-filled area 20 of the external container 10 exhibiting vigorous circulating flowing movements putting the water into rotation.
  • a centrically positioned, downwardly conically tapering, bowl-shaped body 30 is disposed, said body having a lower aperture receiving an upwardly flow of air more or less freed from its contaminating particles.
  • the motor 24' of the suction fan 24 is mounted on a cross of mounting bars 40.
  • the hood 12 has an upper, centrally directed outlet for cleaned air.
  • the hood 12 including mounting bar cross 40, fan 24 and motor- 24' are removably disposed on the upper circular end edge face of the external cylindrical container 10. Subsequently to the removal of the hood with these components, an access possibility from above is created to the interior components.
  • a central column 42 extends supportedly from the perforated bottom 16 to the underside of the fan motor housing 24 ' .
  • the inverted bowl-shaped bodies 32, 36 are attached to the column 42.
  • a mechanical filter may possibly be disposed.
  • the shown water-based air cleaning apparatus can be connected to the pipe network through a device for permanent water supply/periodically replacement in a manner known per se.

Abstract

Dans ce dispositif de nettoyage d'air au moyen d'eau, on fait passer l'air pollué dans un bain d'eau situé dans le dispositif, à l'aide d'un ventilateur (24). Le dispositif peut se composer d'un contenant (10) doté d'un orifice d'entrée (22) destiné à l'air non traité et d'un orifice de sortie (12') destiné à l'air traité et pur. Le contenant (10) entoure de manière concentrique un contenant intérieur (14), formant un espace annulaire (18) entre les faces opposées des contenants (10, 14), la face intérieure du fond du contenant extérieur (10') étant espacée d'une certaine distance de la face opposée de la paroi inférieure (16) du contenant intérieur (14), laquelle paroi présente des trous d'écoulement traversants (26) servant à l'aspiration de l'air et de l'eau dans le contenant intérieur, à partir du bain d'eau placé dans la zone inférieure (20) du contenant extérieur (10). L'orifice d'entrée (22) de l'air non traité s'étend préférablement de manière tangentielle par rapport au contenant cylindrique extérieur (10), provoquant ainsi la rotation de l'air et de l'eau d'arrivée, lors du fonctionnement du dispositif.
