Definitions

  • the invention relates to a method and a device for conditioning at least one process area.
  • conditioning systems In weaving machines for cleaning or dedusting of machine zones, in particular the supplied warps, conditioning systems are known which direct a directed air jet with relatively high flow rate to the process area to be conditioned via a slot-shaped outlet opening and dedust the machine zones, in particular the warps, by blowing off.
  • the slot-shaped outlet extends transversely to the warp over its full width and emits a directed against the warp beam conditioned air.
  • the conditioning size in these conditioning systems is the absence of dust or purity and possibly also the air humidity of the process area, in particular the warp threads.
  • a certain disadvantage is the relatively high induction by entrainment and mixing with ambient air, which is generally not or less conditioned, which reduces the conditioning performance, in particular increases the dust input to the conditioned air by induction-induced intake of dust from the ambient air.
  • Such systems are for example in EP 0 558 718 B1 described as prior art.
  • a method and a device for conditioning of looms are known in which the climate is locally influenced directly on the loom, so a space area is conditioned on the weaving machine.
  • a flow referred to as a "piston-like displacement flow” is understood to mean approximately uniform distribution over its full cross section and an approximately equal speed. Outlet speeds between 0.3 and 1.2 m / s are set for the air flow.
  • the climate air is at this known system used for wetting the warp of the loom.
  • Conditioner size is therefore the moisture content of the air.
  • the room and process air can be controlled with a climate system.
  • the invention is based on the object of specifying a method and a device for conditioning a process in at least one process area, in which the disadvantages mentioned in the prior art are at least partially reduced or completely avoided.
  • the apparatus according to claim 12 is suitable for conditioning at least one process area or process in at least one process area and / or performing a method according to the invention and comprises means for generating at least one conditioning gas stream to be fed to the or each process area; wherein at least one conditioning gas stream comprises at least one primary gas stream and at least one secondary gas stream, the secondary gas stream substantially completely enclosing the primary gas stream and the primary gas stream having at least a higher average flow rate than the secondary gas stream.
  • the invention is based on the idea of embedding or enclosing a stream of primary gas at a comparatively high flow rate in a secondary flow of gas at a lower flow rate.
  • the secondary gas flow thus surrounds the primary gas flow at a peripheral surface or outer surface enclosing the flow lines or flow direction of the primary gas flow, so that ambient air can not enter the primary gas flow directly from there.
  • the induction of ambient air in the rapidly flowing primary gas flow and thus a distortion of the conditioning of the primary gas flow through the ambient air is thus reduced or even completely prevented.
  • the primary gas stream with the high flow velocity also carries with it the secondary gas flow and aligns with it in accordance with the flow guidance of the primary gas stream.
  • a conditioning gas flow is generated, which has quite a comparable directional characteristic as a known air jet according to the aforementioned prior art, but on the other hand, less sensitive to a negative effect on the conditioning by induction of ambient air than an air jet in the prior art.
  • the primary gas stream (s) are generally at least partially turbulent, while the secondary gas stream (s) is at least partially diffused and / or at least partially laminar.
  • the average flow rate of the or each primary gas stream is preferably at least twice, in particular at least five times and preferably at least ten times higher than the mean flow velocity of the or each associated secondary gas stream.
  • the average flow rate of the or each primary gas stream at least initially, is between about 6 m / s and about 20 m / s and / or the mean flow velocity of the or each secondary gas stream, at least initially, between about 0.1 m / s and about 2 m / s.
  • At least one and preferably each primary gas flow is adjusted along a predetermined or predefinable main flow direction or in the manner of a jet. It is particularly advantageous if the primary gas stream aligns and / or stabilizes the secondary gas flow at least approximately parallel to the primary gas flow and / or along the set main flow direction.
  • the secondary gas flow in turn reduces the induction of non-conditioned ambient air through the primary gas flow, in particular practically completely.
  • At least one primary outlet opening is provided and for the or each secondary gas flow at least one secondary outlet opening surrounding the primary opening (s).
  • At least one primary gas stream is divided into an inner partial stream and at least one outer partial stream, wherein the secondary gas stream is passed together with the outer partial stream of the primary gas stream and the outer partial stream substantially completely surrounds and the inner partial stream of the primary gas stream initially within at least one Flow channel (primary flow channel) is guided separately from the outer partial flow and downstream is reunited with the outer partial flow.
  • Flow channel primary flow channel
  • At least one outer partial flow of the primary gas flow preferably flows at least partially along the outer side of the flow channel for the inner partial flow.
  • the flow direction of the inner partial flow of the primary gas flow in the flow passage generally corresponds at least at the exit from the flow passage substantially the main flow direction of the primary gas flow after union of the inner partial flow and outer partial flow.
  • the primary gas flow or the inner partial flow of the primary gas flow or the flow channel can be adjusted or moved within a predetermined solid angle range, in particular continuously or periodically and / or pivotally, oscillatingly or circling.
  • the process area to be conditioned or conditioned is then generally within the solid angle range detected by the primary gas flow or its inner partial flow.
  • the conditioning gas stream initially decreases in its flow cross-section to a constriction area in which the conditioning gas flow has the smallest flow cross-section, and then widens again.
