Definitions

  • This invention relates to a fluid treatment unit for fabric or cellulosic material including a manifold for such a fluid treatment unit as well as a fluid treatment method.
  • WO03/038364A1 discloses a waste heat recovering device, cleaning-water auto-filtering device, and exhaust gas regenerating device for tenters.
  • textile (TX) woven by a weaving machine is dipped in a mixture of water, resin, and chemicals in a settling tank (ST), dehydrated by a mangle (MG), and dried and heat-treated using several chambers (CH1 to CH4) so as to improve its quality.
  • Each of the chambers (CH1 to CH4) comprises a main body (CM) surrounded with an insulating material (IS), and hundreds of hot-air nozzles (HN) for jetting hot air to an upper and a lower side of the textile (TX) passing throughout the center of the main body (CM).
  • CM main body
  • IS insulating material
  • HN hot-air nozzles
  • the hot-air nozzles (HN) are set on several hot-air distribution boxes (HD) connected to a hot-air pipe (HP), and the hot air heated by a heater (HT) cycles in the hot-air pipe (HP) using a hot-air blower (HB).
  • Each of gas exhaust pipes (GP) is set on an upper side of each of the chambers (CH1 to CH4), the gas exhaust pipes (GP) communicate with one main gas exhaust pipe (GM), and an exhaust-blower (BW) is connected to the main gas exhaust pipe (GM).
  • cold air flowing into each chamber through its inlet and out through its outlet is mixed with air cycling in the chamber and heated by the heater (HT) to a predetermined temperature
  • the heated hot air flows by the hot-air blower (HB) through the hot-air pipe (HP) and hot-air distribution boxes (HD) to the hot-air nozzles (HN)
  • the textile (TX) passing between the upper and lower hot-air nozzles (HN) is dried or heated by the hot air jetted through the hot-air nozzles (HN).
  • the above said device does not enable a symmetrical and uniform air impingement to the material (fabric).
  • US Patent No. 4,586,268 teaches a horizontal heat treatment tunnel for the treatment of fibers, threads, slit film or the like fibrillary material used in the textile field, wherein the material to be heat treated is transported side-by-side along a travel path, in endless length form, through the horizontally arranged tunnel, said tunnel comprising a heat-insulated housing having a treatment chamber, an inlet means for allowing entry of the material and an outlet means for allowing withdrawal of the material from the housing; a fan chamber; fan means arranged within said fan chamber for effecting circulation of a gaseous treatment medium within said housing and through said treatment chamber; heater means disposed downstream of said fan means in the treatment chamber for heating said treatment medium before the treatment medium contacts fibrillary material moving along said travel path through said treatment chamber; fan intake connecting means positioned solely to draw the gaseous treatment medium away from the travel path; fan exhaust means positioned solely to direct the gaseous treatment medium toward the travel path through the fibrillary material and toward the fan intake connecting means; said fan intake connecting means including
  • Stenters and similar equipment like hotflues relax driers or belt driers are used for hot air treatment of fabrics, especially for drying, heat setting or the so-called finishing in relatively broad textile or paper fabric.
  • the fabric to be treated is continuously guided through the so-called fields or chambers using a suitable transport system, which chains in case of stenters which have holding fixtures for the two edges of the product and with screen belts in case of relax driers, where the fabric is subjected to hot air (also known as process air) in order to dry the fabric and to heat-set by heating to a certain temperature or to enable certain chemical reactions during the so-called finishing.
  • hot air also known as process air
  • the hot air that is typically heated up to temperatures of 220°C is applied using many nozzles to one or both sides of the fabric which is continuously guided past the nozzles.
  • the hot air is distributed using the so-called nozzles which are arranged above and / or below the fabric and to which the pre-heated hot air is supplied using at least one blower.
  • the nozzle fingers which are mirror symmetrically designed, discharge the hot air via a nozzle plate, which is facing the fabric, using a number of equidistant holes that act as hot air nozzles.
  • the cross-section and geometry of the holes can be different.
  • the hot air can also be discharged via one or several elongated slots.
  • nozzles that are restricted by using housing walls in the paper plane direction are arranged one behind the other in the transportation direction of the fabric, referred to as longitudinal direction below, i.e., at right angles to the paper plane.
  • longitudinal direction i.e., at right angles to the paper plane.
  • transverse direction The direction at right angles to the transportation direction of the fabric is referred to as transverse direction below.
  • the individual nozzles are arranged in the longitudinal direction with a space such that there are gaps through which the "used" hot air can flow back to an exhaust chamber.
  • the hot air is heated here, for e.g., using a forced-air burner, which is an example of a hot air treatment setup using a direct heating system.
  • indirect heating systems like e.g. stream or oil circulation heating systems, can be used.
  • the heated air from chamber is then mostly re-fed to the inlet of the blower.
  • a part of the process air in which substances (for e.g. water, finishing chemicals or residual solutions from the spinning process and fabric pre-treatment), that evaporate or sublimate from the fabric, get accumulated and which also contain the combustion gases of the forced-air burner in case of direct heating systems, is removed from circulation air via an exhaust pipe using an exhaust fan (s).
  • the disadvantage of this design is a flow-related effect which causes the hot air stream from the nozzle to be inclined in the (air) flow direction, i.e. nozzle end and not at right angle to the fabric plane.
  • the angle of inclination is a result of the arc cosine of the ratio-sum of the air outlet cross section area to the air-inlet cross-section area of a nozzle.
  • the result of this is that the air striking the fabric is not deflected uniformly to the right and left in the transverse direction but more air flows to the right in direction of the nozzle end than in the opposite direction.
  • This resulting difference in heat transfer results in an unacceptable different fabric wastage in the edge area, both during drying as well as during the setting and finishing processes (the so-called right/left non-uniformity).
  • the nozzles are staggered for obtaining a perpendicular air discharge, i.e., the nozzles are provided with a compensation angle with respect to the vertical plane using a zigzag-shaped design of the nozzle wall, which compensates the discharge angle as accurately as possible in case of the "straight" non-staggered nozzles.
  • This approach however is significantly more complex in terms of production and results in additional aerodynamic losses due to the slightly zigzag shaped nozzle wall that is folded.
  • the problem of the non-uniform treatment of the fabric described here can be basically prevented by supplying the air to the nozzle at the centre with respect to the transverse direction and by tapering the nozzle from the centre to both the sides, which typical resembles the dome shape of a chimney.
  • the hot air is likewise not discharged vertically from the individual nozzles everywhere. In fact, there is a slightly diverging angular distribution to both the sides.
  • the nozzles are mounted such that they can be moved in the transverse direction for maintenance purposes and can be easily removed from the side opposite to the air feed for maintenance and cleaning purposes.
  • An adequately pressure-tight connection to the feed channel can be implemented using a simple flange with gaskets in the area of plane against which the nozzles are pressed with a pre-load in the assembled condition.
  • the height of the treatment chamber would also have to be increased in general to accommodate a central hot-air feed channel.
  • the objective of this invention is to develop a fluid treatment unit of simple construction for treatment of fabric, cellulosic or other fibrous material comprising at least one manifold for blowing the fluid onto the fabric or cellulosic.

  • Yet another object of the present invention is to provide a fluid treatment unit which does not pose any disadvantages as compared to a conventional nozzle in terms of maintenance and assembly space requirements.
  • a further object of the present invention is to provide a fluid treatment method with low design cost and which is aerodynamically efficient, in which a symmetric fluid distribution can be obtained with good treatment results.
  • the central feed channel (42) of the manifold (38, 40) is designed as an integral unit.
  • the height of the two distribution channels (48, 50) tapers to the sides and that the central feed channel (42) and one of the distribution channels (48) are separated by a common wall (60) in at least a part of the area.
  • the central feed channel (42) has a taper towards the centre that is complementary to the profile of the adjacent distribution channel (48).
  • an initial flow guide (54) is provided in the first transition area between the central feed channel (42) and the distribution channels (48, 50), which divides the stream of fluid into two partial streams for the two distribution channels (48, 50) and deflects it by about 90°.
  • a second flow guide (52) is provided in a second transition area which connects to the first transition area and protrudes into the two distribution channels (48, 50), which basically guides the two partial streams symmetrically in the direction of the two distribution channels (48, 50).

  • an additional flow guide (58) is provided at one front end of the said wall (60) between the said central feed channel (42) and the adjacent distribution channel (48).
  • the nozzle plate (44) has many oval, circular, rectangular or slot-shaped outlet openings (62).
  • the walls of the said outlet openings (62) can be arranged normally to the surface of the nozzle plate (44) or longitudinally at an angle to this and wherein the outlet openings (62) can be arranged in one or several rows, with or without offset to each other.
  • the nozzle plate (44) has at least one narrow slot as outlet opening (62) which extends across a large part of the transverse length of the manifold.
  • rows of several manifolds (38, 40) are provided on both sides of the fabric or cellulosic material (12) to be treated, between which spaces are provided for discharging the fluid blown out through the outlet openings (62), wherein the respective rows of manifolds (38, 40) are staggered on both sides with respect to each other in such a manner that the spaces and outlet openings (62) are at least partially opposite to each other.
  • fluid is continuously blown onto the surface of the fabric or cellulosic material (12) which is continuously guided past at least one manifold (38, 40) having a nozzle plate (44), characterised by the steps
  • the fluid treatment unit has a port (46) for entry of fluid, especially hot air, a central feed channel (42) which guides the hot air from the port to a central area of the manifold (38, 40), as well as two distribution channels (48, 50) that extend on both sides of the central area and are fed by the central feed channel (42) and which distributes and blows the hot air on the fabric (12) via the nozzle plate (44).
  • a port (46) for entry of fluid, especially hot air a central feed channel (42) which guides the hot air from the port to a central area of the manifold (38, 40), as well as two distribution channels (48, 50) that extend on both sides of the central area and are fed by the central feed channel (42) and which distributes and blows the hot air on the fabric (12) via the nozzle plate (44).
  • centre or central area does not necessarily have to mean the exact geometric centre of the manifold (38, 40) in the transverse direction but should include certain part of the central area of the manifold (38, 40). It is rather the geometric centre of the fabric (12) guided through the system in the transverse direction which is relevant for a uniform treatment result.
  • the manifold (38, 40) design of the invention does not pose any disadvantages compared to a conventional nozzle in terms of maintenance and assembly space requirements. Since individual corrective measures for the discharge angle such as stumbling edges and staggering of the manifold (38, 40) can be avoided and the central fed channel (42) is simple in design and is aerodynamically advantageous to implement, excellent aerodynamics can be achieved with little effort, which reduces the manufacturing cost of the assembly as well as the energy consumption of the system.
  • the central feed channel (42) is shown as an integral unit with the manifold (38, 40).
  • the two distribution channels (48, 50) preferably taper towards the sides and the central feed channel (42) and at least one of the distribution channel (42) are separated by a common wall (60) at least in a partial section.
  • the central feed channel (42) preferably has a taper that is complementary to the profile of the adjacent distribution channel (48).
  • the central feed channel (42) can be implemented with minimum design effort, wherein the maximum assembly height of the manifold (38, 40) can remain unchanged.
  • the central feed channel (42) can also be designed as a separate pipe provided the central feed channel (42) and the manifold (38, 40) can be removed from the system as a common unit.
  • An initial flow guide (52) is preferably provided in the first transition area between the central feed channel (42) and the distribution channels (48, 50), which divides the hot air stream into two partial streams for the two distribution channels (48, 50) and deflects it by about 90°.
  • a second flow guide (52) is preferably provided in a second transition area which connects to the first transition area and protrudes into the two distribution channels (48, 50), which basically guides the two partial streams symmetrically in the direction of the two distribution channels (48, 50).
  • the second flow guide (52) can be provided with a passage for supplying hot air to the outlet openings (62) that are located directly in the centre and to which the flow is otherwise partly affected.
  • the nozzle plate (44) can be designed differently, it can especially include many oval, circular, rectangular or slot-shaped outlet openings (62), wherein the walls of the outlet openings (62) can be arranged normally to the surface of the fabric (12) or at an angle to this surface and wherein the outlet openings (62) can be arranged in one row or in several rows, arranged with or without offset to each other.
  • the nozzle plate (44) may also have at least one narrow slot as outlet opening (62) which extends across a large part of the transverse length of the manifold (38, 40).
  • rows of several manifolds (38, 40) are proposed on both sides of the fabric (12) to be treated, between which spaces are provided for discharging the air blown out through the outlet openings (62), wherein the respective rows of manifolds (38, 40) are staggered on both sides with respect to each other in such a manner that the spaces and air outlet openings (62) are at least opposite to each other.
  • a method for addressing the task of hot-air treatment of the fabric (12) mentioned at the beginning, in which hot air is continuously blown onto the surface of the fabric (12) which is guided past at least one manifold (38, 40) having a nozzle plate (44).
  • the method consists of the following steps:
  • a manifold (40) as per the invention has a nozzle plate (44) according to figure 1 through which the hot air is blown onto a fabric (12) (not shown in figure 1 ), above the manifold (40) in this case. This takes place using outlet openings (62) that are equidistantly arranged and which are designed in the nozzle plate (44) using circular holes. Below the flat nozzle plate (44), the manifold (40) is separated from the surrounding area by a manifold housing (64).
  • the hot air or process air is fed into the manifold (40) through a port (46).
  • the hot air that is fed is first guided to a central area of the manifold (40), with reference to the transverse section, via a central feed channel (42). From there, the air stream is basically divided into two parts which flow into two distribution channels (48, 50) that are arranged on both sides of the centre. These distribution channels (48, 50) are immediately adjacent to the nozzle plate (44) such that the hot air can be discharged through the outlet openings (62) and blown onto to the fabric (12) located above it.
  • the two distribution channels (48, 50) are closed at the end.
  • the height and thus the cross-sectional area of the distribution channels (48, 50) reduce in the outward direction. This geometry is technically calculated such that approximately the same amount of air is discharged from all the outlet openings (62), regardless of their distance from the centre.
  • Figure 2 shows a perspective view of a fluid treatment, especially hot air treatment unit according to one of the preferable embodiment of the invention with one upper manifold (38) and one lower manifold (40), in which the flow pattern to be adjusted as per the invention is also indicated by using arrows schematically and qualitatively.
  • the fabric (12) to be treated is in turn located between the two manifolds (38, 40).
  • the air is not discharged from the nozzle plates (44) of the two manifolds (38, 40) at right angles to the nozzle plate (44) but at a specific angle, which depends on the ratio of the sum of the air outlet cross-sections to the air inlet cross-section in the manifold (38, 40).
  • the flow pattern is symmetric to the centre of the manifold (38, 40) with a slightly diverging flow pattern caused by feeding the hot air at the centre of the distribution channels (48, 50), which ultimately results in a uniform treatment result.
  • the diverging angle results in a flow component from inside to the outside for a part of the hot air that is discharged from the manifolds (38, 40), which is more advantageous in terms of treating stretch fabrics (12) compared to a continuous vertical flow pattern, because it causes a certain spreading effect on the fabric(12).
  • the hot air is fed via a port (46) into the manifolds (38, 40) from one side.
  • This configuration makes it easy to remove the manifolds (38, 40) for maintenance purposes.
  • the manifolds (38, 40) can be removed (in the drawing) to the right side by using a guide rail (not shown) through a maintenance access on the side of the stenter range, wherein the port (42) is automatically separated from the hot air feed.
  • the port (42) is pressed with a pre-load against the hot air feed at the end of the displacement path such that an adequately air-tight connection is guaranteed.
  • the hot air flowing in through the port (46) is guided to the central area of the manifolds (38, 40) via the central feed channel (42).
  • This central feed channel (42) narrows down complementary to the widening of the distribution channel (48), with which the central feed channel (42) shares a wall (60).
  • This design of the central feed channel (42) saves material and the overall assembly height of the manifold (40) is also not increased. By tapering the central feed channel (42) towards the central area, the hot air is still accelerated as desired.
  • the air stream is divided into two partial streams that are approximately equal by stream divider plate (54) shortly before the end of the central feed channel (42).
  • the two parts of the stream are then deflected by approximately 90° using an approximately 90° bend in the stream divider plate (54) and a corresponding bend in the initial flow guide (56) provided on the manifold housing (64), such that the two parts of the stream initially flow onto the nozzle plate (44) more or less perpendicularly.
  • a second flow guide (52) which is connected to the first stream divider plate (54), then deflects in each case one component of the two stream parts to the left or right, such that most part of the hot air streams at least flow to the left and right distribution channel (48, 50).
  • an additional flow guide (58) is provided at one front end of the common wall (60) between the central feed channel (42) and the left distribution channel (48).
  • the said additional flow guide (58) is approximately located on the manifold housing (64).
  • Second flow guide (52) slightly affects the flow to some of the outlet openings (62) of nozzle plate (44), that is, the outlet openings (62) that are located at the centre. This is compensated by the fact that the second flow guide (52) has a passage through which the air can pass in the direction indicated by the dashed arrow and can flow into the manifold (40) area in question.
  • manifold (40) width that affects the flow needs to be adjusted to the actual width of the fabric (12), this can be easily implemented as part of this invention by using flow flaps at the desired positions in the distribution channels (48, 50) which prevent air flow in the peripheral areas of the distribution channels (48, 50), in addition to the generally known solutions where the outer manifold outlet openings (62) are closed using a slider or something similar.
