Definitions

  • the process space can also be considered as a zone that repeats in the longitudinal direction of the furnace for different temperatures and air flows.
  • Object of the present invention is to provide an oxidation furnace of the type mentioned in such a way that a required distance of the oxidative treatment of the fibers housed in a smaller volume of the furnace, in particular the furnace can be built lower.
  • the furnace can be kept lower. This has a number of advantages: Since few serpentine passages of the fibers through the process space are required, pulleys for the threads and lock devices, which prevent leakage of air in the area of the entry and exit of the threads in the process space, can be saved. In addition, there is a weight saving for the entire furnace, which has a favorable effect on the costs of a steel construction on which the furnace is constructed. In addition, the quality of the product obtained increases due to the better air circulation of the threads in the process area.
  • inlet openings communicating with the process space are provided in two opposite sides of the suction boxes.
  • the proportion of the air which is not already sucked off at the inwardly directed inlet openings can be determined, but the gaps between the suction boxes are flowed through to the outside.
  • lock devices are provided in the inlet regions of the housing, which have for each between the suction boxes intermediate space communicating with this air space, which is separated from the outside atmosphere by a closure wall having only passages for the fibers, and which is acted upon with pressurized air.
  • This fresh air under overpressure reliably ensures that even the hot air coming from the process space and passing through the spaces between the extraction boxes can not escape from the furnace. What ultimately enters the outer atmosphere through the end wall is only the pressurized air in each of them Intermediate spaces that originate from the outside atmosphere.
  • the oxidation furnace 1 comprises a housing 2, which in turn is composed of two vertical longitudinal walls 2a, 2b, two vertical end walls 2c, 2d, a top wall 2e and a bottom wall 2f.
  • the housing 2 is gas-tight with the exception of two areas 3, 4 in the end walls 2c and 2d, in which the fibers to be treated 20 are executed and executed and which are provided with special lock devices 22, gas-tight.
  • FIG. 2 how the particular FIG. 2 can be seen, the interior of the housing 2 through a vertical partition 5 in the actual process chamber 6 and laterally of this lying air ducts 7, 8, 9, 10, 11, 12 divided. Overall, the interior of the oxidation furnace 1 is substantially mirror-symmetrical to that in FIG FIG. 2 indicated vertical center plane SS formed.
  • two counter-rotating air circuits are maintained: Starting, for example, from the suction devices 14, 15, the air in the sense of in FIG. 2 recognizable arrows through the air ducts 7 and 12 to a filter 16 or 17 and then passed through a heating unit 32a and 32b in the air guide 8 and 11 respectively. From the air duct 8 and 11, the heated air is sucked by a fan 31a and 31b and blown into the air ducts 9 and 10 respectively. From there, the air in each case passes into one half of the injection device 13, from there in opposite directions flowing into the process chamber 6 and from there to the suction device 14 and 15, whereby the two air circuits are closed.
  • outlets 30a, 30b are provided in the wall of the housing 2. These can be used to remove those gas or air volumes which are produced either during the oxidation process or as fresh air via the intake and exhaust air Exit areas 3, 4 enter the process space 6, so as to maintain the air balance in the oxidation furnace 1 upright.
  • the discharged gases, which may also contain toxic components are fed to a thermal afterburning. The heat thus obtained can be used at least for pre-damping the fresh air supplied to the oxidation furnace 1.
  • blow boxes 18 in each of the two stacks are arranged one above the other at a slight distance; the two stacks of blow boxes 18 are again, viewed in the longitudinal direction of the furnace or movement direction of the threads 20, also spaced from each other. Ideally (and deviating from the ones in FIG. 1 shown ratios) is the vertical distance between two blow boxes 18 in a stack the same as the distance between the two stacks 18 in the longitudinal direction of the process room 6.
  • the two suction devices 14, 15, of which in the FIGS. 1 and 2 left with the reference numeral 14 in FIG. 3 is shown, are essentially formed by a respective stack of suction boxes 19 which extend in a similar manner as the blow boxes 18 in the transverse direction through the entire process space 6 and are formed at their transversely to the longitudinal extent of the process space 6 extending narrow sides as perforated plates 19a.
  • the holes in the perforated plates 19a can have any geometric shape.
  • the suction boxes 19 in the suction devices 14, 15 have the same vertical distance from each other as the blow boxes 18 in the injection device 13.
  • the air flows in the area of the suction device 14 are in FIG. 3 represented by arrows.
  • a considerable part of the air coming from the middle region of the process chamber 6 enters the interior spaces of the suction boxes 19 via the perforated plate 19a facing the center of the process space 6 and is further circulated from there, as described above.
  • Another part of the air coming from the central region of the process chamber 6 flows through the spaces between the superimposed suction boxes 19 and is sucked through the outer perforated plate 19a of the suction boxes 19 also in the interior of the suction boxes 19 and fed from there to the further air circulation.
  • the fibers to be treated 20 are fed to the oxidation furnace 1 via a deflection roller 21 and thereby pass through a lock device 22, which in the FIGS. 1 and 3 not yet shown exactly and this serves to prevent any gas escaping from the process space 6 to the outside.
  • the fibers 20 are then passed through the interstices between superimposed suction boxes 19, through the process space 6, through the spaces between superposed Einblashimsten 18 in the Einblas observed 13, through the space between superimposing Absauglasten 19 at the opposite end of the process chamber 6 and through a further lock device 22 ,
  • the described passage of the fibers 20 through the process space 6 is repeated several times in a serpentine manner, for which purpose a plurality of deflecting rollers 24 and 25 lying parallel one above the other with their axes are provided in both end regions of the oxidation furnace 1.
  • the fibers 20 leave the oxidation furnace 1 and are thereby guided over a further deflection roller 26.
  • the serpentine passage of the fibers 20 through the process space 6 they are surrounded by hot, oxygen-containing air and thereby oxidized.
  • at least one oxidation stage is essentially completed. Further oxidation states can follow.
  • FIG. 4 is similar to in FIG. 3 a vertical section through an end portion of an oxidation furnace 101, which corresponds to that of the FIG. 3 is similar, but with respect to the lock device 123 shows more details.
  • the suction devices 115 are formed by a stack of superimposed extraction boxes 119.
  • the suction boxes 119 of the FIG. 4 only provided on the narrow side facing outward with gas inlet openings, while the opposite narrow side, which faces the center of the process space 6, is closed.
  • angle profiles 125 are attached, which extend transversely to the flow direction of the air (indicated by arrows). These angle profiles 125 have the task to increase the air resistance and to even out the suction.
  • an individually adjustable throttle valve (not shown) may be provided to keep the extracted volume flow for each suction box 119 the same.
  • the lock device 123 comprises an outer, folded, profiled sheet 126 as a closure wall to the outside atmosphere, which is provided with corresponding passage openings 127 at those points in which the threads 120 pass through.
  • an air channel 128 is attached, which can be supplied in the direction of the arrow 129 with pressurized fresh air.
  • angled air baffles 130 are integrally formed or attached to the air channel 128. As shown in the drawing and symbolized by small arrows, narrow passages for the air, which in this way in particular reach the region of the openings 127 in the sheet 126, arise between these air guide plates 130 and the sheet 126.
