Definitions

  • the first of these processes quite generally is the treatment with hot water for removing the acid and at the same time t he volatile substances as carbon bisulphide (CS2) and sulphurated hydrogen (I-IzS).
  • CS2 carbon bisulphide
  • I-IzS sulphurated hydrogen
  • the invention applied for avoids these disadvantages, making it possible, to get the gas under pressure and lead it away, without mixing it with air. This is achieved by closing oi hydraulically the room in which the removing of acid and gases from the threaded material is executed. The material is fed and discharged continuously throughout the hydraulic closures in and from the chamber, To avoid premature gas development on the entrance of the material into the apparatus, this point is kept cool by an influx of cold water.
  • the apparatus for this proceeding will be described by means of the drawing. They are adapted to treat the material as a continuous band or cut into sections.
  • Figs. 1-3 and 4-6 show 2 forms of construction for the treatment of the material as band.
  • Figs. 7-8 and 9-10 show 2 forms of construction for the treatment of the cut material.
  • Fig. 1 is a cross section of Fig. 2 on line 2-2.
  • Fig. 2 is a cross section through Fig. 1.
  • Fig, 3 is a plan view of Figs. 1 and 2.
  • Fig. 4 is a cross-section of Fig. 5 on line 4-4.
  • Fig. 5 is a side view of Fig. 4.
  • Fig. 6 is a plan View of Fig. 4-5.
  • Figs. 7 and 9 are longitudinal sections in direction of the flow of material
  • Figs. 8 and 10 are side views of Figs. 7 and 9 respectively.
  • the apparatus consists of the two connected containers I'I and I4 with continuous cold water inux I I through pipe I5 into container I1.
  • the water is discharged through pipe I8 to overow I9.
  • Container I4 is fed with hot water through pipe 24.
  • This entrance is provided above Water-level 21 into a chamber 28.
  • the latter is iled with Raschigrings, balls or the like, through which the Water runs into the treatment rooms.
  • the gases developed escape under pressure through chamber 28 and pipe I6and in this way get washed with the hot water.
  • the treatment room I4 may also be supplied with hot water or steam through the pipe 25 controlled by the valve 34. However, it preferably concerns an additional feeding of the room I4 while the main supply ofv hot water takes place through the pipe Z4 in counterow to the escaping gas.
  • the band of threads I3 runs continuously through pipe I5 over roller 20 through the container I1 and through the opening in the bottom or' container I4 over the rollers ZI and 22, driven by the wheel 26, winds itself around them several times, being guided by means of the leading sticks 36, then passes through a second opening in the bottom or' container I4 over guiding roller 23 and through pipe I8 for the /next treatment.
  • Container I4 is red with hot water in the manner already described or is heated by means of steam and so brought to the temperature customary for removing the acid and the volatile substances, The hot water, now containing acid passes through the outlet hole for the band in the bottom of container I4 to container Il and from here to the exterior as described. In this way the chamber I4 serves at the same time for removing acid and volatile substances as usual, so that the removing of gases if carried out in the manner described does not require any additional heat or hot water.
  • FIG. 4-6 show another form of the apparatus
  • the cylinders 2 I22 may also be arranged side by side instead of vertically, furthermore it is possible to replace the cylinder 22 which is not driven as well as the rollers 23, 23 by guiding sticks.
  • the apparatus for the continuous treatment oi' material already cut, designed in Figs. 7-8 and 9-10 are preferably a connection of two syphonlike containers, i'orming together a channel in form of the letter W.
  • 'I'he material I3 goes continuously in uniform flow from the cutter or transporter into the entrance of the ilrst syphon Il in. the direction oi the arrow I3, under addition of cold water Il for Iavoiding premature gas evolution.
  • 'I'his emulsion or watery mixture of the material now gets into the second syphon 32, according to Figs. 7-8, under the inuence of the level diierence 29, 21 and from here under the influence of the level difference 21 I, 30 to the open for further treatment.
  • FIG. 9-10 A further arrangement for the transport of the material through the apparatus is shown in Figs. 9-10.
  • the transport is effected by means of the piston 3
  • the transport also may be effected by means of any other device as for instance transporting rollers (not shown).
  • the syphonlike channel is iltted with chambers 2l of which sloping openings or slits lead into the interior oi the channel.
  • hot water or steam is supplied in direction of the ilow of material and causes the lheating up of the emulsion or watery mixture to the temperature needed for removing the acid and volatile substances.
  • Hot water is furthermore supplied in the manner already described through pipe 24 and chamber 23. The gases escape under pressure after having been washed asdescribed above through chamber 23 and pipe I6. The room for removing of the acid and gases is shut oi!
  • Apparatus for deacidifying and degassing artincial viscose fibers for recovering CS2, Hi8 and other gases in a continuous manner comprising a closed hot water illled chamber, hydraulically closed inlet and outlet means on said chamber forv the bers being treated, said means communicating with said chamber anda chamber on the top of and communicating with said first chamber, i
  • said last named chamber being provided with an inlet for hot water and an outlet for gas.
