Definitions

  • the contaminated indoor air is introduced into the filter material using a suitable fan.
  • the main pollutants that pollute the indoor air and damage health are: -non-respirable dusts and aerosols (particles below 5 ⁇ m)
  • the advantage of this system lies in the self-cleaning of the filter material by the soil bacteria, which break down the absorbed pollutants from the activated carbon surface.
  • the polluted room air is drawn in by the semi-radial fan 4. It passes through the ventilation grille 5 attached in the housing wall 1 and the behind it coarse dust pre-filter 6 in the lower housing part.
  • the fan pushes the air into the air distribution system 3, from where it passes through nozzles into the inner container 2, which contains the filter material 7.
  • the room air flows through the filter material and then exits the filter surface in a cleaned manner.
  • the cleaned room air absorbs water through the moist filter material.
  • the filter ensures adequate air humidification and thus a pleasant indoor climate, according to the recognized method of cold evaporation.
  • the housing cover 8 is mainly used for decorative purposes and to accommodate the controls. However, the controls can also be attached to the housing wall.
  • the system can be equipped with an automatic permanent irrigation, hydrometer, speed control, timer or air quality controller.
  • the inner container is flanged with a loose seal 13 on the outflow side of the fan. This makes it easy to disassemble the system.
  • the inner container is removable but is airtightly fastened in the housing.
  • the air distribution system consists of assembled and glued plastic ventilation duct elements with a rectangular cross-section.
  • the air distribution system is shown as a ring system. However, this can be variably adapted to every inner container shape.
  • On the underside of the air distribution system there are evenly distributed bores (i.e. nozzles) 15 of approx. 3 mm from which air can flow evenly into the filter material.
  • the holes are on the underside of the air distribution system to prevent irrigation water from entering.
  • the filter material consists of a mixture of open-pore clay granulate, approx. 20% activated carbon and approx. 5% garden compost. Since the open-pore clay granulate has a very high water storage capacity, there is no need for a water reservoir.
  • the introduced compost provides an additional enrichment with soil bacteria to break down the pollutants on the activated carbon.
  • the activated carbon used can consist of pellets (pressed pieces) or broken carbon (granules). The plants specially selected for this purpose are inserted into the filter material with bales of earth.
  • the shape and size of the housing as well as the individual design can be adapted to the spatial conditions and customer requirements.
  • the plant containers used as housings can be made of plastic, metal, stone or wood.
  • the design of the housing as a hexagon, as the sketches show, is only one exemplary embodiment which is mounted on rollers 10.
  • the ventilation grilles are embedded in sufficient numbers next to each other on the circumference of the housing wall.
  • the coarse dust pre-filters installed behind prevent premature compression of the filter material by particles.
  • the coarse dust pre-filters can be replaced with the removable ventilation grilles.
  • the semi-radial fan is dimensioned according to the filter size (i.e. volume, area and height of the filter material).
  • a filter surface load of max. Aimed at 250 m 3 / h per m 2 in order to achieve a laminar flow behavior in the filter material, which also guarantees optimal cleaning performance.
  • the fan must also be able to compensate for the pressure loss caused by the filter material.
  • the inner container contains the filter material and is made of a suitable plastic.
  • a tubular adapter piece 11 is installed in a watertight manner in the bottom of the inner container.
  • the adapter contains the corresponding nominal diameters and serves as a connection between the air distribution system in the inner container and the fan attached under the inner container.
  • the air distribution system fits exactly and is therefore watertightly attached to the adapter and can therefore be easily disassembled if necessary.
  • the semi-radial fan is attached to the center of the housing base with two holding brackets 9. There are rubber dampers 14 between the mounting bracket and the housing base so that vibrations are not transmitted.
  • the fan is movably mounted in the mounting axis.
  • the fan intake is located a few centimeters above the bottom of the housing.
  • the inner container is inserted in the bottom of the top planter in an airtight manner. Seals 12 are located between the individual planters.
  • FIG. 6 shows a schematic top view of a biological room air filter according to a second embodiment
  • FIG. 7 shows a schematic side view in full section of the biological room air filter from FIG. 6;
  • FIG. 8 shows a schematic top view of the biological room air filter from FIG. 7 with the upper housing part removed (section A-A in FIG. 7).
  • FIG. 9 shows a schematic, partially broken side view of a third embodiment of the biological room air filter according to the invention.
  • FIG. 10 shows a schematic side view in cross section of the biological room air filter from FIG. 9.
  • FIG. 7 shows a schematic side view in full section of a second embodiment of the present invention.
  • the biological room air filter comprises an upper housing part 1 1 and a lower housing part 2 '.
  • the upper housing part 1 ' is releasably attached to the lower housing part 2' and can be removed therefrom.
  • the lower housing part 2 ' comprises the air inlet openings 5 for air intake and a water tank 15 for permanent irrigation.
  • the upper housing part 1 ' includes the filter material 7, plants (not shown), the fan unit 4 and the air distribution system 3.
  • an electrical shaft 16 for receiving an electrical control unit for controlling the level in the water tank 15 and the moisture in Filter material 7 formed.
  • a water supply shaft 17 is also formed for filling the water tank 15.
  • the electrical shaft 16 has a panel 18 on which all operating and control devices for the functions of the room air filter are arranged.
  • the control unit is preferably designed to be automatic water supply.
  • the water supply shaft 17 is connected to the water tank 15 via a connecting line 20 and has a flap 19 in order to prevent any odors that may occur in the water tank 15.
  • a pump 21 is arranged in the water tank 15 and is automatically controlled by the electrical control unit in the electrical shaft 16 via moisture-measuring sensors in the filter material 7.
  • the pump 21 is connected to a hose system 22 (see also FIG. 6) and pumps water from the water tank 15 into the hose system 22.
  • the hose system 22 has drip points 23 through which the water can penetrate into the filter material 7.
  • the water tank 15 is preferably closed with a lid 25 (FIG. 8).
  • the filter material 7 preferably consists of several layers:
  • the filter material 7 can be inoculated with pollutant-degrading microorganisms.
  • the room air filter has a dry-running protection, such that the electrical or electronic control unit interrupts the power supply from the fan unit 4 and the pump 21 when the tank level falls below a certain level.
  • the lower housing part 2 is equipped with sound-insulating elements 24.
  • the fan unit 4 is attached directly below the upper housing part 1 'on the outflow side.
  • the air can initially be distributed evenly before it flows into the denser upper layers 7b to 7d.
  • FIGS. 9 and 10 A further embodiment of the room air filter according to the invention is shown schematically in FIGS. 9 and 10.
  • the room air filter is designed here as a wall system with external air intake 27 and water supply 28.
  • the air intake 27 and the water supply 28 are arranged together with the fan unit 4 and the water tank 15 in an external housing 29 and have the corresponding supply lines 30 to the filter module 31.
  • several wall filter modules 31 can also be connected to one another with a supply line 30.
  • the air supply can also take place via ventilation devices already in the room (ceiling or wall suction).
  • the water tank 15 can also be designed as a bubble column 32 for decorative purposes.
  • a water tank 15 can thereby be dispensed with.
  • the wall filter modules 31 can have an integrated lighting unit 33.
