Definitions
- the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 1 1 for improving the suction e.g. with cake extractor hoods, workplace vacuuming, etc., whereby the effectiveness of the extraction is increased by blowing.
- Suction methods are known from DE patent applications 39 18 870 and 1 96 1 3 51 3.3, in which frontal blowing flows are used, i.e. through the interaction of a vortex flow or a curved shear flow with surrounding walls, a limiting or frontal flow is generated, which transports the pollutants to the suction surfaces and concentrates them there
- Blowing out from a slot represents the case of a flat, two-dimensional jet
- blowing out from a round opening represents the case of a round jet.
- a round jet with a diameter D slows down more quickly than a flat one because of increased mixing with the surroundings Beam emerging from a slot of thickness D.
- the object of the invention is to provide a method and a device for generating blow flow fields in a clearly structured manner.
- the blow-out direction can be easily adjusted.
- the range of the blowing flow generated is less than with a slot with the thickness of the hole diameter. This means that it can be blown out at a higher speed without the steam, e.g. is blown on the rear wall of an extractor hood.
- the shape of the blow-out line can be chosen freely. With the invention, the possibility is created to design the frontal generators with slot blowout, as they are the subject of DE 39 18 870 and DE 196 13 513.3, as perforated lines.
- annular blow lines can be formed, which are formed both with a purely radial flow and with a tangential flow component, which e.g. is important for island fume cupboards.
- staggered perforation lines i.e. groupings of perforation lines, can be formed. At the corners there is the possibility to improve the flow by increasing the orientation of the blow-out direction inwards.
- blow flow fields can be generated in a particularly simple manner, which use frontal flow structures or circulating blow flows.
- blow-out openings can either be designed as holes or as bores or use special blow-out nozzles, but the outlet openings can holes of any shape.
- the hole arrangements can also be arranged on surfaces of any shape.
- the structure of the blow-out flow field is determined by the orientation and the diameter of these openings.
