Definitions
- the invention relates to a method for filtering contaminated air, in particular with which an improvement in the degree of odor reduction is achieved, and an apparatus for carrying out the method.
- the device is particularly suitable for use in commercial kitchens and in extractor hoods for the household.
- DE 31 46 537 C1 describes an odor filter with activated carbon as an adsorbent, in which relatively long flow paths are achieved within the activated carbon and the flow or suction conditions in the extractor hood are improved.
- the activated carbon is located in chambers which fill the interior of the filter frame and in which the chamber walls serving as air guiding elements are inclined in the direction of the suction axis.
- Grease filters made of metal are also known, in particular for use in commercial kitchens and in extractor hoods for the household. These consist of expanded metal layers and / or, in the case of eddy current filters, usually of a first row of profiles which are spaced apart and opened in the direction of the gas flow, and a second row of profiles which are spaced apart and opened against the direction of the gas flow, the adjacent longitudinal edges two adjacent profiles of one row each protrude into the interior of an opposite profile of the other row.
- eddy current filters are described in DE 27 20 201 C2 and US Pat. No. 3,910,782. With these separating grids, the distance between the two rows of profiles is dimensioned such that the air flowing through them undergoes a multiple reversal of direction.
- the free passage cross-section is 10 - 30% of the total grating area.
- This reduction in cross-section within the separating grille increases the air speed by 3 to 10 times.
- the separating effect of the grille is based on this increase in speed, which accelerates the liquid droplets and solid particles contained in the air, and on the multiple reversal of direction of the air flowing through.
- the accelerated liquid droplets and solid particles cannot follow the change of direction and hit the inner surface of the profiles of the second row.
- the liquid droplets form a liquid film on their surface, which gradually runs downwards and passes through special openings in the frame of the separating grid into a busbar arranged under the separating grid.
- an additional filter as a unit that can be mechanically detached from the eddy current filter.
- the additional filter consists of a knitted fabric filter and is arranged behind the bowl-shaped, elongated guide plates.
- the detachable connection to the eddy current filter means that the additional filter can be removed and can be cleaned or replaced.
- a dehumidifier in which highly effective, odorless salt crystals extract excess moisture from the room air in a safety cassette and dissolve in the process (product information: Ceresit Anti-Feucht, e-mail: . .- info@henkel.de).
- the object of the invention is to provide a device for filtering contaminated air, with which in particular an improvement in the degree of odor reduction and a reduction in air humidity is achieved. This object is achieved with the characterizing features of method claim 1 and device claim 6, advantageous embodiments are the subject of the dependent claims.
- the method according to the invention for filtering contaminated air in which the air flows through a filter and impurities are separated out, provides for the following process steps which proceed in succession:
- the air is dried by means of zeolites with a higher affinity for water than activated carbon and / or silicate gel and / or inorganic salts, which dissolve slowly in the process and / or by polymer-based absorbers.
- Activated carbon and / or zeolites are used to adsorb odors.
- a device for carrying out the method for filtering contaminated air consisting of several filter elements through which the contaminated air flows is shown in the drawing. Show it:
- Fig. 1 a section through the filter device and Fig. 2: a side view of the filter device.
- the filter device has an eddy current filter 1, expanded metal layers 2, a filter 3 for air drying and an odor filter 4 arranged in a filter housing in the flow direction.
- the filter 3 for air drying and the odor filter 4 are preferably combined in a filter cassette which is interchangeably arranged on the filter housing.
- this filter cassette also has a fill level indicator for the salt area, so that a timely change can be made.
- the filter 3 for drying the air has structures of zeolites through which the contaminated air can flow, with a higher affinity for water than activated carbon and / or silicate gel and / or inorganic salts, which slowly dissolve and / or polymer-based absorbers.
- the invention shows an advantageous embodiment that the salt crystals are not filled in as bulk material, but in an open-cell foam material such.
- B. are integrated open-cell polyurethane foam that holds the salt crystals in place by their embedding.
- the eddy current filter 1 has at least one drain opening 5 in the collecting container 6 for the fat and water separated in the eddy current filter 1.
- the salt solution obtained in the filter 3 can also be discharged via this drain opening 5.
