  • the separator communicates with at least one nozzle which is supplied with water to produce a curtain of water. The sucked air stream flows through the water curtain for the purpose of oil separation.
  • the separated oil is in a collecting device.
  • the object of the invention is to provide a compact, simple device, which reliably eliminates a high proportion of suspended particles from the sucked air flow at a low operating and maintenance costs and low operating costs.
  • the operation of the device should be quiet, around which the cookers operating personnel are only exposed to low noise emissions.
  • the separated from the sucked air flow suspended particles should be easily removable for the operator.
  • the airflow undergoes an at least two consecutive curvilinear deflections in different directions through the inlet chamber designed in accordance with the invention, so that suspended particles guided in the airflow can at least partially deposit on the upper inner surface of the inlet chamber.

  • the advantage is exploited that the gaseous components of the sucked air flow and the air particles moved in the air flow have a different specific gravity and, consequently, a different mass moment of inertia.
  • the forced deflection of the air flow by means of the forced guidance means the fractions of the gaseous media and the suspended particles moved therein are accelerated or decelerated differently across the flow cross section, and the fractions occupy different trajectories in the area of the forced guidance means. Due to the different direction of the successive deflections based on the positive guidance means the separation effect between the fractions is enhanced.
  • the gaseous media can also move in trajectories with narrower radii in the deflection area. In the region of the first deflection, therefore, there is a segregation in such a way that the suspended particles accumulate in the outer region of the air flow.
  • the suction effect generated by the fan acts statically equal over the entire flow area of the air conveyor channel.
  • the moving in the air flow fractions in the air conveyor channel in the field of forced guidance means paths are of different lengths, depending on whether they are in the inner or outer radius of the deflection, they experience depending on their trajectory in dynamic terms, a different degree of acceleration , While the inside of the curve of the air flow is accelerated the most, the fractions moving in the outer curve area are hardly accelerated or decelerated, depending on the conditions and the concrete design.
  • the acceleration differences are all the greater, the closer the inner radius of the deflection is chosen in relation to the free height of the flow cross-section.
  • the deflection in the opposite direction causes an acceleration of the previously slowly moved in the outer radius gaseous media. Due to their inertia, the suspended particles can not participate in this acceleration. Due to the acceleration of the previously surrounding gaseous media, the slowly moving gas envelope becomes thinner, and the faster in the middle Radius range moving air currents press into the area of the accelerated by accelerating the gas envelope. Due to these currents, suspended particles still moving in the air stream receive a movement impulse towards the near outer wall. By means of this effect, also those suspended particles collide with the outer wall and adhere there, which could not be separated with the previously known devices. In the manner described, it is possible to deposit 90% and more of the airborne suspended particles in the form of fat and / or water droplets.

  • the air flow is only slightly hindered, so that only a comparatively low fan performance is required.
  • the lower fan performance reduces operating noise and operating costs due to lower power consumption.
  • the operation is simple, since the hood only needs to be switched on or off and no other operating materials, monitoring and maintenance are required. It suffices to occasionally wipe the surface of the inner wall in the area of the positive guidance means. The surface can be made easy to clean in this area. Due to the high degree of separation of airborne particles, the fan, the downstream exhaust air ducts and the recirculation mode, the room air is hardly burdened by not separated suspended particles.
  • the purified air stream is also characterized by a lower content of moisture compared to the air stream outside the inlet chamber, so that neither fungal growth nor bacterial growth can be observed in the exhaust chamber and in the air conveying channel.
  • the device remains permanently clean, there are no more hygienic loads or health hazards for the operating personnel from the presence of the hood. Also, the efficiency during long-term operation of the device according to the invention largely remains due to the sufficiently large the floating particles serving as baffle and Abscheide Scheme
  • the guidance of the air flow preferably takes place arcuately by means of correspondingly designed smooth inner surfaces of the Air duct to avoid disturbing stalls or turbulence through which also suspended particles could be thrown back into the air flow. This reduces drag and noise, and smooth surfaces are easier to maintain. It is also advantageous to keep the air delivery channel as short as possible, since the design and the production cost can be kept very small.

Other cross sections are possible as long as only the double deflection takes place along the general conveying direction AB.
  • the front section 8 explained in more detail in the preceding exemplary embodiment, viewed from the working principle, is nothing else than the lower positive guide means 60 arranged on the base plate 4 in FIG. 16.
  • the separating surface 10 explained in more detail in the preceding exemplary embodiment is a forced guiding means 60, such as it is shown in Fig. 16 in the upper region of the air conveying channel 3 at the bottom of the upper plate 5.
  • the path that the air flow through the arranged in the air conveyor channel 3 forced guidance means must be outlined by the outgoing from the point A arcuate arrow in its course.
  • the positive guidance means 60 protrude by the height H into the air conveying channel 3.
  • the free height of the flow cross-section of the air conveying channel 3 is thereby reduced to the dimension h.
  • the air flow is guided around a forced guidance means 60 in a particularly narrow radius. Due to the different ways that the air flow must travel at different heights of the flow cross-section along the respective radius, considerable differences in speed occur in the air flow.
  • Fig. 17 the bending radii, around which the air flow is guided around in the region of the positive guidance means 60, explained in more detail.
  • the forced guidance means 60 are shown in dashed lines.
  • the air conveyor channel 3 is designed by arcuate baffles so that the air flow can flow through the region of the double deflection in a laminar flow as possible.
  • the front section 8 which is also contained in the embodiment explained in more detail above, the circular arcuate surface of which is guided around a transverse axis lying on the point P1.
  • the deflection of the guided in the air conveyor duct 3 air flow corresponds a deflection angle ā‡ , which is significantly greater than 90 Ā° in the embodiment.
  • a deflection angle ā‡ which is significantly greater than 90 Ā° in the embodiment.
  • the angle ā‡ which is smaller than 90 Ā° in the embodiment.
  • the arc of the inner surfaces of the air conveyor channel 3 is guided in the region of the second deflection about a transverse axis, which is spatially approximately in the position P2.
  • the direction of rotation of the angle ā‡ deviates from that of the angle ā‡ .
  • the angles shown in the embodiment are to be understood as exemplary only, a different size and distribution of the angle ā‡ , ā‡ is possible.
  • Fig. 18 the different wind speeds of the air flow in the air conveying channel 3 are shown, in particular the different velocity distribution as a function of the position of the measuring point in the region of the respective deflections. While the wind speed over the free height h of the air conveyor channel 3 in the region of position I is still approximately the same, the air flow in the region of position II moves over the free height of the flow cross section at different speeds. While that portion of the air flow that moves along the inner surface of the first deflection must travel only a short distance and therefore undergoes additional acceleration, those components of the air flow that move in the outer region of the air flow in the region of the first deflection, a travel much larger way. In these zones, therefore, slows the air velocity.
  • the position III shows the velocity distribution after passing the air flow of the second deflection. Since the parts of the air flow moving in the outer curve region in the region of the first deflection are in the inner curve in the region of the second deflection, these air flow components must travel a shorter distance here, while the parts of the air flow previously moved in the inner curve now move outside. Due to these reverse track conditions, inverse acceleration or deceleration effects result. Since a small dead space 61 forms in the slipstream of the front section 8, in which turbulence can occur, the outside portion of the air flow becomes in the region of the second deflection slowed down more than the more central parts of the air flow.
  • a kind of "nozzle effect" can be achieved if the air delivery channel 3 is formed so that between the peak H1 shown in Figure 19 of the first positive guidance means 60 and the high point H2 of the second forced guidance means 60 in the flow direction, a height offset by the amount V in the free height (h) of the flow cross-section of the air conveyor channel 3 results.
  • a medium-flow zone may be formed in which the airflow may flow through the air delivery passage 3 at a high speed and low power loss.
  • FIG. 20 shows a preferred embodiment of the device according to the invention, in which the front region 9 of the upper plate 5 is divided into two parts.
  • the front region 9 can consist of two, for example, quarter-arc-shaped front regions, made of z. B. a front portion 9a and a rear portion 9b exist.
  • the tongue plate 15 with the front portion 9 a z. b. be pulled out parallel to the center longitudinal axis of the air conveyor channel 3 by the maximum length e.
  • the free height h in the region of the inlet opening 1 thereby increases approximately by the amount e to the height h (e).
  • Such a measure has only negligible effects on the flow conditions essential to the invention in the region of the height h shown in FIG.
  • the front region of the upper plate can be divided into two.
  • the front region may consist of two, for example, quarter-arc-shaped front areas, z. B. a front portion and a rear portion, exist.
  • the tongue plate with the front portion can z. b. parallel to the center longitudinal axis of the air conveyor channel, to be pulled out.
  • Fig. 21 the different trajectories of the air flow and the suspended particles in the course of the air conveyor channel 3 are shown. While the airflow is shown in a continuous curved line, the various possible trajectories of the suspended particles are shown in dashed lines.
  • An influence on the trajectory has first of all the density and spatial form of a suspended particle. Depending on how large and heavy a suspended particle and how its outer shape is designed, a single suspended particle is accelerated to different degrees by the surrounding air flow. In general, it can be stated that the suspended particles moving in the region of the inner curve - assuming the same shape and density - experience a stronger acceleration pulse than in the outer curve area moving suspended particles.
  • the suspended particles in the outer circle have a different mass inertia than the gaseous components of the air flow, so that inevitably results in the course of the flow through the region of the first deflection, a trajectory that differs from a beaten around the pivot point P1 circular path. Due to the interaction of the kinetic energy inherent in the suspended particles, their inertia and the gravitational forces acting on them, the suspended particles invariably reach the area of the outer air flow during the passage through the zone of the first deflection and inevitably collide with the inner surface of the latter due to the course of their trajectory upper plate 5. In this way forms on the upper plate 5 a Abscheide sequencing 10, the spatial extent is indicated by the line shown in Fig. 21. As can be seen from Fig. 21, trajectories of suspended particles may intersect.
  • Fig. 22 an example is shown in which the suspended particles occupy trajectories that do not cross. While the airborne particles moved in the curve inner area initially follow the flow direction of the air flow and are accelerated in the inner radius, they take after the acceleration an approximately straight trajectory. The suspended particles moving in the outer area follow the air flow over a longer distance, but finally collide with the inner surface of the upper plate 5. Whether the trajectories of the suspended particles intersect more as shown in Fig. 21, or rather run parallel as in Fig. 22 is ultimately dependent on the specific flow conditions in the air conveyor channel 3, the density and shape of the suspended particles, the density and speed of the air in the conveying channel 3 moving gases and the selected radii of curvature and dimensions of the air conveyor channel 3.
  • the deposition of the invention also works when the double deflection is arranged in a middle or rear portion of a conveyor channel 3.
  • the inlet opening 1 need not be rectangular, but may have any geometry.
