    Air exhausting means, intended primarily for catering industry kitchens or equivalent. The air exhausting means (10) comprises an outer housing (11), an exhaust chamber (12) with at least one air aperture or grease filter unit (13), a collecting chamber (25) for gaseous impurities and a blow chamber (18). The blow apertures (20) of the blow chamber of the air exhausting means are disposed to produce a blow jet which induces a secondary air jet, which has on all sides of the blow apertures (20) been arranged to act on its entirety in the proximity effect area. Above the blow apertures (20) of the blow chamber (18) has been disposed a guide baffle (21), arranged to direct the blow jet (31) towards the grease filters (13) so that the maximally efficient starting impulse of the blow jet is achieved, this impulse being arranged to substantially die out before arriving at the grease filter (13).

    (54) DEVICE FOR REMOVAL OF AIR
    (57) The invention relates to an air purge device for public kitchens or other similar catering establishments. The device comprises a housing, an exhaust chamber 2 with a suction inlet and a grease filter 5, a collection chamber 3 for harmful gaseous impurities, and a purge chamber 4 with an overflow device and a guiding threshold 15. In the purge chamber there is a hole 11 to create a jet that induces a secondary stream of air spreading in all directions from the openings 11. Above the openings is a guide threshold 15, which directs the blowing stream to the grease filters 5, so that the maximum initial impulse is reached jet, which largely attenuates before you get to the grease filter. 2 hp ff, 7 ill.

    The invention relates to devices for de-airing, in particular for use in kitchens of catering establishments or similar enterprises.
    The aim of the invention is to increase the degree of air purification in kitchens to improve the microclimate in these rooms.
    Figure 1 shows a device for venting, vertical section; figure 2 - node I in figure 1; FIG. 3 shows the air flow of the air removal device; figure 4 - diagram of the air flow around the purge holes; on fig.Z - purge hole; 6 is a top view of the blowing streams directed by the blowing holes; FIG. 7 is the same vertical section.
    The air removal device includes an outer casing 1, a exhaust chamber 2, a collection chamber 3 for gaseous pollutants, and a purge chamber 4. The exhaust chamber 2 has one or more fat filters 5. The figure 6 denotes a fat channel and a collecting box . The fat filter filters 5 are provided with a valve 7, with which the flow of air through the filters 5 is regulated. In addition, the exhaust chamber 2 contains a connection 8 connected to a piping system to remove air, as well as an adjustment valve 9, with which the quantity I will air

    ha, getting into the piping system. The adjustment valve 9 may also serve as a fire damper. The differential pressure measurement points are indicated by 10. The amount of air blown and exhaust is determined by means of the differential pressure AP, measured by the differential pressure measurement points.
    The blowing chamber 4 has in its lower part a grate with blowing holes 11, which are intended to create the necessary initial impulse of blown air. The purge chamber 4 includes a connector 12, which is connected to air inlet channels (not shown), and the connector is provided with an adjustable valve 13, which operates from a drive device 14j.
    located adjacent to the purge ports 11.
      The bypass device is made in the form of blowing holes 11, and the guide threshold 15 located above the blowing holes affects the incoming air flow in such a way that the necessary initial impulse is reached, the directed blowing jet is attenuated before it reaches the fat filter 5. The guide threshold 15 serves as a fat channel from the side adjacent to the purge chamber 4.
    The process is carried out in such a way that in the immediate work zone, shown as 16, the incoming

    the air stream is formed so that its initial impulse is very high. The worker works under the immediate working zone 16. In addition, this actual main jet, or so-called carrier jet 17, creates turbulent regions 18, which create a small vacuum in region 19. This vacuum does not have any harmful effect.
    The inner surface of the purge chamber 4 is non-insulated. a surface that acts as a heat transfer surface to trap heat contained in the air being cleaned, as well as heat emitted by some other heat source, and to transfer the trapped heat to the incoming or blown air passing in the purge chamber 4.
    The purge apertures 11 are arranged in such a way that the distance between the apertures is approximately three times larger than the diameter of the apertures. Due to this, the proposed device achieves the desired effect. The openings 11 are located in such a way that the polluted kitchen air is attracted to the openings as shown in Fig. 4.
    In addition, the openings 11 located along the edges of the air removal unit direct the blowdown jets 17 to the central region of the air removal unit, while the openings 11 located in the center direct the blowdown jets 17 forward. Thus, the blowing jets 17 form
    a real carrier stream 17. The purge jets 17 and the actual carrier jet 17 are in different planes. Blow out jets 17 pass under the carrier stream 17. The holes 11 have sloping edges and may have an elliptical shape.
    Blow out jets 17 act on both edges of the device to remove air in a gap of 50 cm from the edges of the device to remove air towards the center.
